分案申请说明Instructions for Divisional Application

本申请是申请号为02120693.7，申请日为2002年4月3日，发明名称为“墨盒”的专利申请的分案申请。This application is a divisional application of the patent application whose application number is 02120693.7, the application date is April 3, 2002, and the invention name is "ink cartridge".

技术领域technical field

本发明涉及一种墨盒，其在适当的负压状态下响应于打印信号向喷射墨滴的记录头供墨。The present invention relates to an ink cartridge that supplies ink to a recording head that ejects ink droplets in response to a print signal in an appropriate negative pressure state.

背景技术Background technique

一记录装置具有一锁定装置，在该记录装置中一墨水容器可拆卸地安装在具有一个喷墨记录头的滑架上，该锁定装置可防止由于打印操作时滑架的运动而导致的墨盒的移动，并能借助外部操作轻易地卸下墨盒。A recording device having a locking device in which an ink container is detachably mounted on a carriage having an inkjet recording head, the locking device preventing the ink cartridge from being locked due to movement of the carriage during printing operation. mobile, and the ink cartridge can be easily removed by external operation.

例如，如JP-A-10-44451中公开的，构造了这样一种锁定装置，即，与一墨盒支架相接合的一突出部分形成在墨槽相对侧表面的一表面上，而一棘爪形成在另一表面的一枢转杆上。在突出部分与墨盒支架相接合的状态下，棘爪通过将突出部分作为旋转支轴移动另一表面与墨盒支架相接合。For example, as disclosed in JP-A-10-44451, such a locking device is constructed in that a protrusion engaged with an ink cartridge holder is formed on a surface of the opposite side surface of the ink tank, and a pawl Formed on a pivot lever on the other surface. In a state where the protruding portion is engaged with the ink cartridge holder, the pawl engages with the ink cartridge holder by moving the other surface of the protruding portion as a rotation fulcrum.

但，要把适合于靠墨盒旋转而安装墨盒的锁定机构施加给一墨水容器是很困难的，该墨水容器利用与一记录头相连通的供墨针形成墨流通道。However, it is difficult to apply a locking mechanism suitable for mounting the ink cartridge by rotation of the ink cartridge to an ink container forming an ink flow path by means of an ink supply needle communicating with a recording head.

也就是说，因为供墨针具有一预定的长度以确保与墨水容器的可靠连通，当供墨针受到沿非轴向方向的一外力时其就有被弯曲或损坏的危险。因此，墨水容器只能平行于供墨针的纵向方向移动。That is, since the ink supply needle has a predetermined length to ensure reliable communication with the ink container, there is a risk of the ink supply needle being bent or damaged when it is subjected to an external force in a non-axial direction. Therefore, the ink container can only move parallel to the longitudinal direction of the ink supply needle.

而且，如JP-A-9-11500中公开的，其提出这样一种墨盒，即，在其内存储有墨的一容器的相对表面上形成有弹性可变形杆，每个弹性可变形杆都具有一与墨盒支架相接合的棘爪，从而能将墨盒插到供墨针上。Also, as disclosed in JP-A-9-11500, it proposes an ink cartridge in which elastically deformable rods are formed on opposite surfaces of a container in which ink is stored, each elastically deformable rod There is a detent that engages with the ink cartridge holder so that the ink cartridge can be inserted onto the ink supply needle.

此外，如JP-A-2001-105587中公开的，其提出这样一种墨盒，即，一用于存储墨的细长、矩形平行六面体容器沿纵向在一正面侧壁上具有一闩部件，并在正面侧壁附近的相对壁上具有用于导引墨盒插入的突出部分。Furthermore, as disclosed in JP-A-2001-105587, it proposes an ink cartridge in which an elongated, rectangular parallelepiped container for storing ink has a latch member on a front side wall in the longitudinal direction, and A protruding portion for guiding the insertion of the ink cartridge is provided on the opposite wall near the front side wall.

但是，一具有储存墨盒相关信息或类似信息的存储装置的墨盒要求要与微电极可靠连接，且因此要求有可靠的定位。However, an ink cartridge having a storage means for storing information about the ink cartridge or the like requires a reliable connection to the microelectrode and thus requires a reliable positioning.

优选实施例的说明Description of the preferred embodiment

下面将参照附图描述本发明的优选实施例。Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

图1A和1B及图2A至2D表示了根据本发明第一实施例的墨盒外观。图3和图4为表示墨盒装配的透视图。墨盒1主要由一细长的、具有一个开口表面的盒状矩形容器壳体2和用来封闭该开口表面的盖元件3组成。在墨盒1插入方向的前端侧(该实施例中，在容器壳体2纵方向上偏置位置处容器壳体2的底表面上)形成有一供墨口4。在插入或抽出墨盒1时分别作为前侧和后侧的相对壁上部中的容器壳体2上一体形成有锁紧件5和6。1A and 1B and FIGS. 2A to 2D show the appearance of an ink cartridge according to a first embodiment of the present invention. 3 and 4 are perspective views showing the assembly of the ink cartridge. Theink cartridge 1 is mainly composed of an elongated, box-likerectangular container case 2 having an opening surface and acover member 3 for closing the opening surface. Anink supply port 4 is formed on the front end side in the insertion direction of the ink cartridge 1 (in this embodiment, on the bottom surface of thecontainer case 2 at a position offset in the longitudinal direction of the container case 2). Lockingmembers 5 and 6 are integrally formed on thecontainer case 2 in the upper portion of the opposite wall which is the front side and the rear side, respectively, when theink cartridge 1 is inserted or drawn out.

所形成的位于供墨口附近的锁紧件5在插入方向的前端部分(在该实施例中，位于稍高于墨盒下端的部分)具有一转动支轴和一能向外打开的可打开上部。所形成的另一相对的锁紧件6与锁紧件5配合以协助墨盒的固定。The formedlocking member 5 near the ink supply port has a front end portion in the insertion direction (in this embodiment, a portion slightly higher than the lower end of the ink cartridge) having a pivot shaft and an openable upper portion that can be opened outwards. . Anotheropposite locking member 6 is formed to cooperate with thelocking member 5 to assist the fixing of the ink cartridge.

该锁紧件5和6中的每一个都具有一相应于滑架上插入口宽度的宽度，这样每个锁紧件5、6的侧表面就作为导引部分以在宽度方向限定墨盒的位置。Each of thelocking members 5 and 6 has a width corresponding to the width of the insertion opening on the carriage, so that the side surface of each lockingmember 5, 6 is used as a guide to limit the position of the ink cartridge in the width direction. .

此外，在位于供墨口附近的锁紧件5下方设有一存储装置7。存储装置7在一板的外露表面上具有电极7a，其排列成上下两行，同时一半导体存储元件安装在板的背面上并与电极7a相连。另一方面，在另一锁紧件6的下方形成有一阀存储腔8。In addition, astorage device 7 is provided below the lockingmember 5 located near the ink supply port. Thememory device 7 has electrodes 7a on the exposed surface of a board, which are arranged in two rows above and below, while a semiconductor memory element is mounted on the back of the board and connected to the electrodes 7a. On the other hand, avalve storage cavity 8 is formed under the other lockingmember 6 .

在供墨口4附近、容器的中央区域形成有一槽部分9，这样槽部分9至少在墨盒的前端开口并沿墨盒插入/抽出方向延伸。槽部分9具有这样的长度和宽度，即，使至少在供墨口4的前端到达滑架的供墨针之前调节墨盒使供墨口4的开口表面垂直于供墨针。In the vicinity of theink supply port 4, agroove portion 9 is formed in the central area of the container such that thegroove portion 9 opens at least at the front end of the ink cartridge and extends in the ink cartridge insertion/extraction direction. Thegroove portion 9 has such a length and width that the ink cartridge is adjusted so that the opening surface of theink supply port 4 is perpendicular to the ink supply needle at least before the front end of theink supply port 4 reaches the ink supply needle of the carriage.

另一方面，其上安装有墨盒的滑架100在其底部具有一记录头101，以及与记录头101连通的一供墨针(多个供墨针)102，如图5所示。一墨盒紧压件(该实施例中为一片簧103)位于与供墨针102所处区域相分离的一区域内，同时在供墨针102和片簧103之间形成有一定位突起104并沿墨盒插入/抽出方向延伸。并且，电极106位于供墨针102侧的一侧壁105上，以及一凹槽107位于侧壁105的上部以与锁紧件5的一突起5a相接合。On the other hand, thecarriage 100 on which the ink cartridge is mounted has arecording head 101 at its bottom, and an ink supply needle(s) 102 communicating with therecording head 101, as shown in FIG. An ink cartridge pressing member (aleaf spring 103 in this embodiment) is located in an area separated from the area where theink supply needle 102 is located, while apositioning protrusion 104 is formed between theink supply needle 102 and theleaf spring 103 and along the The cartridge insertion/extraction direction extends. Also, anelectrode 106 is located on aside wall 105 on the side of theink supply needle 102 , and agroove 107 is located on an upper portion of theside wall 105 to engage with aprotrusion 5 a of the lockingmember 5 .

通过采用上述结构，如图6A所示，若墨盒1插入滑架时与供墨口4位于后侧且墨盒1压在片簧103上，槽部分9就受到突起104的限制。因此，尽管力图通过位于偏置位置的片簧103将一转动力施加给墨盒1(图6A中箭头A的方向)以使供墨口4一侧向下移动，但墨盒的位置被限定在基本上平行于规定的插入/抽出方向(该实施例中为垂直方向)。By adopting the above structure, as shown in FIG. 6A, if theink cartridge 1 is inserted into the carriage on the rear side with theink supply port 4 and theink cartridge 1 is pressed against theleaf spring 103, thegroove portion 9 is restricted by theprotrusion 104. Therefore, although trying to apply a rotational force to the ink cartridge 1 (in the direction of arrow A in FIG. 6A ) by theleaf spring 103 at the biased position to move the side of theink supply port 4 downward, the position of the ink cartridge is limited to substantially Parallel to the prescribed insertion/extraction direction (vertical direction in this embodiment).

用一放在容器壳体2顶面2b上的手指进一步将墨盒1压向片簧103时，墨盒1产生一分力以将具有存储装置7的墨盒1表面压向滑架100的电极106，因为容器壳体2的顶面2b形成为一具有θ角的斜坡，其中墨盒1的后侧(即锁紧件5一侧)较高。因此，当存储装置7的电极7a与电极106紧密接触时，墨盒就受压并插入供墨针102。在这个压力插入过程中，如图6B所示，锁紧件5的突起5a抵抗锁紧件5的整体弹力，然后陷入凹槽107，这样突起5a就与凹槽107相接合。因此，一明显的咔嗒声传递给手指，使用户感觉到墨盒已牢固地安装在滑架100上。When theink cartridge 1 is further pressed against theleaf spring 103 with a finger placed on thetop surface 2b of thecontainer housing 2, theink cartridge 1 generates a component force to press the surface of theink cartridge 1 with thestorage device 7 to theelectrode 106 of thecarriage 100, Because thetop surface 2b of thecontainer case 2 is formed as a slope with an angle of θ, wherein the rear side of the ink cartridge 1 (ie, the lockingmember 5 side) is higher. Therefore, when the electrode 7a of thememory device 7 comes into close contact with theelectrode 106, the ink cartridge is pressed and inserted into theink supply needle 102. During this pressure insertion process, as shown in FIG. 6B , theprotrusion 5 a of the lockingmember 5 resists the overall elastic force of the lockingmember 5 and then sinks into thegroove 107 , so that theprotrusion 5 a engages with thegroove 107 . Therefore, a distinct click sound is transmitted to the fingers, allowing the user to feel that the ink cartridge is firmly mounted on thecarriage 100 .

尽管锁紧件6也可具有与锁紧件5的突起5a相类似的一突起，但仅在存储装置7一侧的锁紧件5上设置的突起5a可防止墨盒安装错误。这是因为，若没有存储装置7一侧的锁紧件6产生一咔嗒声，用户会错误地断定墨盒已被正确地安装了，尽管存储装置7一侧的锁紧件5还没有位于正确的位置，即，锁紧件5位于还没有产生咔嗒声的位置。Although the lockingmember 6 may also have a protrusion similar to theprotrusion 5a of the lockingmember 5, theprotrusion 5a provided on the lockingmember 5 only on the side of thestorage device 7 prevents incorrect installation of the ink cartridge. This is because, if there is no click sound from the lockingmember 6 on one side of thestorage device 7, the user may mistakenly conclude that the ink cartridge has been installed correctly even though the lockingmember 5 on the side of thestorage device 7 is not in the correct position. The position, that is, the lockingmember 5 is located in the position where no click sound has been produced.

在已经安装墨盒的状态下，因为墨盒1在插入/抽出方向上的位置受到锁紧件5的突起5a的限制，并且具有存储装置7的墨盒1表面受片簧103的推动力(图6A中朝箭头A方向的力)被压向滑架100的电极106，所以无论打印期间产生什么振动，墨盒1与滑架100之间的接触都得以牢固地保持。In the state of having installed the ink cartridge, because the position of theink cartridge 1 in the insertion/extraction direction is limited by theprotrusion 5a of the lockingmember 5, and the surface of theink cartridge 1 with thestorage device 7 is pushed by the leaf spring 103 (in FIG. 6A The force in the direction of arrow A) is pressed against theelectrode 106 of thecarriage 100, so the contact between theink cartridge 1 and thecarriage 100 is firmly maintained regardless of any vibration generated during printing.

另一方面，当要自滑架100中移去墨盒1以更换或出于类似目的时，将锁紧件5弹性地压向容器壳体2，这样锁紧件5就绕着稍高于下端且作为转动支轴的部分转动。结果，锁紧件5的突起5a自凹槽107中释放。当墨盒1在该状态下抽出时，墨盒1在突起(导件)104的导引下靠片簧103的推动力的影响下平行于供墨针102移动。因此，墨盒1能在没有任何弯曲力或类似力作用于供墨针102的情况下自滑架100中移下。On the other hand, when theink cartridge 1 is to be removed from thecarriage 100 for replacement or for similar purposes, the lockingmember 5 is elastically pressed toward thecontainer housing 2 so that the lockingmember 5 is wound around a slightly higher than the lower end. And as part of the rotation fulcrum rotates. As a result, theprotrusion 5 a of the lockingmember 5 is released from thegroove 107 . When theink cartridge 1 is drawn out in this state, theink cartridge 1 moves parallel to theink supply needle 102 under the influence of the urging force of theleaf spring 103 under the guidance of the protrusion (guide) 104 . Therefore, theink cartridge 1 can be removed from thecarriage 100 without any bending force or the like acting on theink supply needle 102 .

图7和图8表示了在组成上述墨盒的容器壳体2内形成的一个流道的例子。容器壳体2由基本水平伸展的壁10分割为上下部。7 and 8 show an example of a flow path formed in thecontainer case 2 constituting the above ink cartridge. Thecontainer case 2 is divided into upper and lower parts by awall 10 extending substantially horizontally.

下部包括第一墨室11。框架14限定了上部，壁10在其底部连续延伸。容器壳体2的壁12与框架14相分离而形成一预定间隙，这样该间隙就形成了一空气连通通道13。框架14进一步由一垂直壁15分割为两部分，而形成在框架14底部上的一连通孔15a位于左边。两部分之一形成为第二墨室16，另一部分则形成为第三墨室17。The lower part includes thefirst ink chamber 11 . Theframe 14 defines an upper part, at the bottom of which thewall 10 extends continuously. Thewall 12 of thecontainer case 2 is separated from theframe 14 to form a predetermined gap, so that the gap forms anair communication passage 13 . Theframe 14 is further divided into two by avertical wall 15, and a communication hole 15a formed on the bottom of theframe 14 is located on the left. One of the two parts is formed as thesecond ink chamber 16 and the other part is formed as thethird ink chamber 17 .

第一墨室11内、第二墨室16下部形成有一吸入通道18，同时吸入通道18连接着第二墨室16的底部16a与容器壳体2的底部2a。在本实施例中，吸入通道18进一步构造为在容器壳体2的正面形成有一凹进部分18c(图9A)，同时用一不透气膜57密封凹进部分18c。Asuction passage 18 is formed in thefirst ink chamber 11 and the lower part of thesecond ink chamber 16 , and thesuction passage 18 connects the bottom 16 a of thesecond ink chamber 16 and the bottom 2 a of thecontainer housing 2 . In this embodiment, thesuction passage 18 is further configured to form a recessed portion 18c ( FIG. 9A ) on the front surface of thecontainer case 2 while sealing the recessed portion 18c with an air-impermeable film 57 .

在吸入通道18的下部形成有一具有连通孔19a和19b的壁19。在吸入通道18一端相对的部分处形成有一喷孔20以由外部向容器壳体2内喷墨，而另一与第一墨室11相连通的孔21平行于喷孔20而形成。In the lower portion of thesuction passage 18 is formed awall 19 having communicatingholes 19a and 19b. Anorifice 20 is formed at a portion opposite to one end of thesuction passage 18 to eject ink from the outside into thecontainer housing 2 , and anotherorifice 21 communicating with thefirst ink chamber 11 is formed parallel to theorifice 20 .

距框架14的上表面14a一预定间隙的壁22、24和26分割了第三墨室17。在第三墨室17内，壁10、24、26和27限定了第四墨室23，并且壁24限定了与压差阀存储腔33的背面相连通的一流道(图10)。Thewalls 22 , 24 and 26 at a predetermined gap from the upper surface 14 a of theframe 14 divide thethird ink chamber 17 . Within thethird ink chamber 17, thewalls 10, 24, 26 and 27 define thefourth ink chamber 23, and thewall 24 defines a flow channel communicating with the back of the differential pressure valve storage chamber 33 (FIG. 10).

壁24的下部与壁10之间设有具有一连通孔26a的分割壁26。这样设置下部具有一连通孔27a的分割壁27，即，在分割壁27和框架14之间形成一墨水通道28。通过作为过滤室的一通孔29，墨水通道28的上部与墨盒1的正面侧连通。在通孔29内插入一由多孔材料制成的过滤器55(图3)。图8中，参考数字2c表示一凹部，用于储存存储装置7。Between the lower portion of thewall 24 and thewall 10, apartition wall 26 having a communication hole 26a is provided. Thepartition wall 27 having a communication hole 27a at the lower portion is provided such that anink passage 28 is formed between thepartition wall 27 and theframe 14. As shown in FIG. The upper part of theink passage 28 communicates with the front side of theink cartridge 1 through a throughhole 29 as a filter chamber. A filter 55 made of a porous material is inserted into the through hole 29 (FIG. 3). In FIG. 8, reference numeral 2c denotes a recess for storing thememory device 7. In FIG.

如图8所示，与壁27相连接的壁30限定了通孔29，其通过一凹部29a与墨水通道28的上端连通，同时还通过容器壳体2正面上的一水滴型凹部30a(图9A)与位于流道上部的一凹部24a相连通，流道被分割在位于压差阀存储腔33背面的壁34与壁24之间。As shown in Figure 8, thewall 30 that is connected withwall 27 has defined throughhole 29, and it is communicated with the upper end ofink channel 28 by a recess 29a, also passes through a drop-shaped recess 30a on the front ofcontainer housing 2 simultaneously (Fig. 9A) communicates with a recess 24a located on the upper part of the flow channel, and the flow channel is divided between thewall 34 and thewall 24 located at the back of the differential pressurevalve storage cavity 33 .

压差阀存储腔33的下部通过一流道与供墨口4互相连接，该流道由容器壳体2正面的凹槽35(图9A)组成，同时不透气膜57(图10)覆盖凹槽35。The lower part of the differential pressurevalve storage chamber 33 is interconnected with theink supply port 4 through a flow channel, which is formed by a groove 35 ( FIG. 9A ) on the front side of thecontainer housing 2 , while an air-tight film 57 ( FIG. 10 ) covers the groove 35.

如图9A所示，容器壳体2的正面上形成有一窄槽36、一宽槽37及一凹槽38。窄槽36迂回曲折以提供尽可能大的流阻。宽槽37绕窄槽36排列。凹槽38为矩形且位于第二墨室16的相对区域。框架39和肋40形成在矩形凹槽38内，以在高度上略低于矩形凹槽38的开口表面。一具有斥墨性和透气性的可透气膜(未示出)伸展并粘结在框架39和肋40上，这样就限定了一空气连通室。凹槽38的底部形成有一通孔41，其与第二墨室16的壁42所限定的一细长区域43(图7)相连通。窄槽36在相对于透气膜更接近正面侧的位置与凹槽38连通。区域43的另一端通过一通孔44、一连通槽45及一通孔46(图9B)与阀存储腔8连通。As shown in FIG. 9A , a narrow groove 36 , a wide groove 37 and a groove 38 are formed on the front surface of thecontainer housing 2 . The narrow slots 36 meander to provide as much flow resistance as possible. Wide grooves 37 are arranged around narrow grooves 36 . The groove 38 is rectangular and located in the opposite area of thesecond ink chamber 16 . The frame 39 and the rib 40 are formed in the rectangular groove 38 to be slightly lower than the opening surface of the rectangular groove 38 in height. A gas-permeable film (not shown) having ink repellency and gas permeability is stretched and adhered to the frame 39 and the ribs 40, thus defining an air communication chamber. A through hole 41 is formed at the bottom of the groove 38 , which communicates with an elongated region 43 ( FIG. 7 ) defined by thewall 42 of thesecond ink chamber 16 . The narrow groove 36 communicates with the groove 38 at a position closer to the front side with respect to the gas permeable membrane. The other end of theregion 43 communicates with thevalve storage chamber 8 through a throughhole 44 , acommunication groove 45 and a through hole 46 ( FIG. 9B ).

在墨盒插入方向上阀存储腔8的前端(本实施例中阀存储腔8的下部，如图8所示)形成并开有一窗口8a，这样能如后面所述安装一墨盒识别块70(如图3、图4和图12所示)。墨盒识别块70允许在记录装置壳体的滑架100上的一阀操作杆和许多识别件110，111和112(如图5中所示)插入。The front end of thevalve storage chamber 8 in the ink cartridge insertion direction (the bottom of thevalve storage chamber 8 in the present embodiment, as shown in Figure 8) is formed and has a window 8a, so that an ink cartridge identification block 70 (as shown in Figure 8) can be installed as described later Figure 3, Figure 4 and Figure 12). Thecartridge identification block 70 allows insertion of a valve operating lever and a plurality ofidentification members 110, 111 and 112 (shown in FIG. 5) on thecarriage 100 of the recording device housing.

图10为一剖视图，表示了压差阀存储腔33附近的结构。一弹簧50和一隔膜阀52存储在压差阀存储室33内。隔膜阀52由一种可弹性变形的材料形成，例如人造橡胶，并在其中央具有一通孔51。隔膜阀52包括一位于圆周的环形厚部52a及与厚部52a形成为整体的一框架54。隔膜阀52经由框架54固定在容器壳体2上。弹簧50的一端依靠隔膜阀52的一弹簧接纳部分52b支承，另一端依靠一盖元件53的一弹簧接纳部分53a支承，盖元件固定在存储腔33的开口上。FIG. 10 is a sectional view showing the structure near thestorage chamber 33 of the differential pressure valve. Aspring 50 and adiaphragm valve 52 are stored in the differential pressurevalve storage chamber 33 . Thediaphragm valve 52 is formed of an elastically deformable material such as elastomer, and has a throughhole 51 at its center. Thediaphragm valve 52 includes a circumferentially annular thick portion 52a and aframe 54 integrally formed with the thick portion 52a. Thediaphragm valve 52 is fastened to thecontainer housing 2 via aframe 54 . One end of thespring 50 is supported by a spring receiving portion 52b of thediaphragm valve 52, and the other end is supported by a spring receiving portion 53a of acover member 53 fixed to the opening of thestorage chamber 33.

参考数字56和57代表粘结在容器壳体2的正面侧和开口表面侧的不透气膜。不透气膜56通过焊接或类似方法粘结在壁10，框架14以及壁15、22、24、26、27、30和42上(图7和8)。这样形成在容器壳体2正面上的窄槽36和压差阀存储腔33被不透气膜57覆盖。Reference numerals 56 and 57 denote air-impermeable films bonded to the front side and the opening surface side of thecontainer body 2 . Gasimpermeable membrane 56 is bonded to wall 10,frame 14 andwalls 15, 22, 24, 26, 27, 30 and 42 by welding or the like (Figs. 7 and 8). The narrow groove 36 thus formed on the front surface of thecontainer housing 2 and the differential pressurevalve storage chamber 33 are covered with an air-impermeable membrane 57 .

在这种结构中，流过墨流孔34a的墨水被隔膜阀52阻塞。在这种状态下当供墨口4处的压力降低时，隔膜阀52克服弹簧50的推动力远离阀座34b移动，这样墨水流过通孔51并经由凹槽35形成的流道流向供墨口4。In this structure, the ink flowing through the ink flow hole 34 a is blocked by thediaphragm valve 52 . In this state, when the pressure at theink supply port 4 decreases, thediaphragm valve 52 moves away from thevalve seat 34b against the urging force of thespring 50, so that the ink flows through the throughhole 51 and flows to the ink supply via the flow path formed by the groove 35.Mouth 4.

当供墨口4处的墨压增加至一预定值时，隔膜阀52在弹簧50的推动力下开始与阀座34b弹性接触。结果，墨水的流动被中断。通过重复该操作，墨水被排放给供墨口，而维持一恒定的负压。When the ink pressure at theink supply port 4 increases to a predetermined value, thediaphragm valve 52 comes into elastic contact with thevalve seat 34b under the urging force of thespring 50 . As a result, the flow of ink is interrupted. By repeating this operation, ink is discharged to the ink supply port while maintaining a constant negative pressure.

图11为一剖视图，表示了用以与空气相连通的阀存储腔8的结构。限定阀存储腔8的壁上钻有一通孔60。一由弹性材料例如橡胶形成的挤压件61可移动地插入通孔60中，从而挤压件61的圆周处于由容器壳体2支承的状态。一阀体65位于插入方向上挤压件61的前端，这样阀体65就由一下端靠突起63固定且中心部分受突起64限制的弹性件62支承，比如一片簧。阀体65一直被推向通孔60。Fig. 11 is a sectional view showing the structure of thevalve storage chamber 8 for communication with air. A throughhole 60 is drilled in the wall defining thevalve storage chamber 8 . A pressingmember 61 formed of an elastic material such as rubber is movably inserted into the throughhole 60 so that the circumference of the pressingmember 61 is in a state supported by thecontainer body 2 . Avalve body 65 is located at the front end of the extrudingpart 61 in the insertion direction, so that thevalve body 65 is supported by anelastic member 62 whose lower end is fixed by theprotrusion 63 and whose central part is limited by theprotrusion 64, such as a leaf spring. Thevalve body 65 is always pushed toward the throughhole 60 .

图12中所示墨盒识别块70安装在挤压件61的另一表面上。Thecartridge identification block 70 shown in FIG. 12 is mounted on the other surface of the extrudedmember 61 .

墨盒识别块70由一通过棘爪70a和70b而固定在墨盒的一凹槽80(图9A)上的底座组成。底座由许多槽(本实施例中有三个槽71、72和73)和一臂74形成。三个槽71、72和73中的每一个都平行于墨盒插入方向延伸并在墨盒的横向方向上具有预定的宽度。在本实施例中，在墨盒插入方向侧上的槽72内(本实施例中插入方向的后端)设有臂74以压迫挤压件61。这些槽71、72和73的深度是这样设定的，即使这些槽71、72和73能接收各自的识别件。The inkcartridge identification block 70 consists of a base secured to a groove 80 (FIG. 9A) of the ink cartridge bydetents 70a and 70b. The base is formed by a number of slots (in this embodiment threeslots 71 , 72 and 73 ) and anarm 74 . Each of the threegrooves 71, 72 and 73 extends parallel to the ink cartridge insertion direction and has a predetermined width in the transverse direction of the ink cartridge. In this embodiment, anarm 74 is provided in thegroove 72 on the cartridge insertion direction side (rear end in the insertion direction in this embodiment) to press the pressingmember 61 . The depths of thesegrooves 71, 72 and 73 are set such that thesegrooves 71, 72 and 73 can receive the respective identification members.

臂74绕一支轴74a枢转从而进一步向内设置，并具有一拉出端(本实施例中臂74在插入方向上的前端部分)，其斜向伸入操作杆113(图14)的插入通路内。Thearm 74 is pivoted around a shaft 74a so as to be further inwardly disposed, and has a pull-out end (the front end portion of thearm 74 in the insertion direction in this embodiment) that obliquely extends into the end of the operation lever 113 (FIG. 14). inserted into the pathway.

此外，在槽71、72和73内分别形成有突起部件71a、72a和73a，以分别面对滑架100的识别件110、111和112的上端。In addition, protrudingparts 71a, 72a and 73a are respectively formed in thegrooves 71, 72 and 73 to face the upper ends of theidentification pieces 110, 111 and 112 of thecarriage 100, respectively.

在上述结构中，当臂74的位置被固定时，用以接合的突起部件71a、72a和73a的位置和相应识别件110、111和112的位置也依照墨盒内容纳的墨水种类被设定。因此，这就可防止错误地安装墨盒。若用以接合的突起部件71a、72a和73a的位置既能在墨盒插入方向又能在墨盒宽度方向变化，则用以接合的突起部件71a、72a和73a就可采用一立体排列结构。因此，这就可识别相当多种类的墨水而不增加识别区域的形成面积。In the above structure, when the position of thearm 74 is fixed, the positions of the protrudingparts 71a, 72a and 73a for engagement and the positions of thecorresponding identification members 110, 111 and 112 are also set according to the kind of ink contained in the ink cartridge. Therefore, this prevents the ink cartridges from being installed by mistake. If the positions of the protrudingparts 71a, 72a and 73a used for engagement can be changed both in the ink cartridge insertion direction and in the width direction of the ink cartridge, then the protrudingparts 71a, 72a and 73a for engaging can adopt a three-dimensional arrangement structure. Therefore, it is possible to recognize a considerable variety of inks without increasing the formation area of the recognition area.

图13和图14表示滑架上已安装有墨盒的一个实施例。滑架是这样构造的，即，使许多墨盒(本实施例中有一个黑色墨盒和三种彩色墨盒)可安装在滑架上。Figures 13 and 14 show an embodiment in which ink cartridges have been installed on the carriage. The carriage is constructed such that a plurality of ink cartridges (one black ink cartridge and three color ink cartridges in this embodiment) can be mounted on the carriage.

也就是说，宽度比其它稍大的第一安装区120位于一侧上，宽度相互相等的第二、三和四安装区121、122和123由滑架相对侧穿过126的肋124和穿过129的肋127限定，从而与第一安装区120相邻。That is to say, the first mountingarea 120 having a slightly larger width than the others is located on one side, and the second, third, and fourth mountingareas 121, 122, and 123 having widths equal to each other are formed by therib 124 and therib 124 passing through 126 on the opposite side of the carriage. Therib 127 is defined by thepassage 129 so as to be adjacent to thefirst installation area 120 .

如参照图5的说明，每个墨盒安装区具有与记录头101相连通的供墨针102，与供墨针102所处区域相分离区域内的挤压件(该实施例中为片簧103)，以及位于片簧103与供墨针102间沿墨盒插入/抽出方向伸展的定位突起104。此外，形成有一凹槽107’以导引锁紧件5侧上墨盒的侧端部分。As explained with reference to FIG. 5, each ink cartridge installation area has anink supply needle 102 communicated with therecording head 101, and an extruding member (in this embodiment, a leaf spring 103) in an area separated from the area where theink supply needle 102 is located. ), and apositioning protrusion 104 extending between theleaf spring 103 and theink supply needle 102 along the ink cartridge insertion/extraction direction. In addition, a groove 107' is formed to guide the side end portion of the ink cartridge on the lockingmember 5 side.

此外，电极106位于接近供墨针102的一侧壁105上。在侧壁105的上部，形成有凹槽107以与锁紧件5的突起5a相接合。在凹槽107附近，形成有一凹槽107a，以与自锁紧件5侧端部分上突出的锁紧件5的突起5b(图1和2)相接合。In addition, theelectrode 106 is located on theside wall 105 close to theink supply needle 102 . On the upper portion of theside wall 105 , agroove 107 is formed to engage with theprotrusion 5 a of the lockingmember 5 . In the vicinity of thegroove 107, agroove 107a is formed to engage with theprotrusion 5b (FIGS. 1 and 2) of the lockingmember 5 protruding from the side end portion of the lockingmember 5. As shown in FIG.

同样，如图5和14所示，与锁紧件6相接触的滑架区域形成有一凹槽109以导引锁紧件6的侧端部分，以及一与自锁紧件6侧端部分突出的锁紧件6的突起6b(图1和2)相接合的凹槽109a。Equally, as shown in Figure 5 and 14, the carriage region that contacts with lockingmember 6 is formed with agroove 109 to guide the side end portion of lockingmember 6, and a protruding from lockingmember 6 side end portion. The groove 109a that theprotrusion 6b (Figures 1 and 2) of the lockingmember 6 engages.

在本实施例中，定位突起104是这样构造的，即，如图15A所示，形成有一平行于墨盒正面伸展的侧端部分104a以确保细长突起104的定位可靠性和强度。对应于定位突起104，如图15B所示，墨盒的槽部分9被这样构造，即，至少墨盒插入方向的前端形成有一对着侧端部分104a的凹槽9a，凹槽9a对着墨盒的正面侧开口。In this embodiment, thepositioning protrusion 104 is constructed such that, as shown in FIG. 15A, a side end portion 104a extending parallel to the front surface of the ink cartridge is formed to ensure positioning reliability and strength of theelongated protrusion 104. Corresponding to thepositioning protrusion 104, as shown in FIG. 15B, thegroove portion 9 of the ink cartridge is constructed such that at least the front end in the insertion direction of the ink cartridge is formed with a pair of grooves 9a facing the side end portion 104a, the groove 9a facing the front of the ink cartridge Side opening.

在供墨针102周围形成有与肋4a相啮合的肋102a，每个肋4a的截面为U形且墨盒的供墨口4被夹入其间。通过这些肋，就可将墨盒维持在供墨针102插入到供墨口4内的状态下。Around theink supply needle 102 are formed ribs 102a engaging withribs 4a each having a U-shape in section with theink supply port 4 of the ink cartridge being sandwiched therebetween. With these ribs, the ink cartridge can be maintained in a state where theink supply needle 102 is inserted into theink supply port 4 .

安装到宽度较大的第一安装区120上的大容量型墨盒基本上具有与上述实施例中墨盒(图1和2中所示的小容量型墨盒)相同的结构，如图16A至16C所示。一容器壳体2’构造为具有与容器壳体2相同形状的开口表面，但其深度W被设置为比容器壳体2的深度大。因此，仅通过改变容器壳体2’的深度W，就可增加容器壳体2’内容纳的墨量。顺便提及的是，在图16A和16B中，与图1和图2中具有相同功能的部件用一致的但以一单引号标注的附图标记。The large-capacity ink cartridge mounted on the first mountingarea 120 having a larger width basically has the same structure as that of the ink cartridge (the small-capacity ink cartridge shown in FIGS. 1 and 2) in the above-described embodiment, as shown in FIGS. 16A to 16C. Show. A container case 2' is configured to have an opening surface of the same shape as thecontainer case 2, but its depth W is set to be larger than that of thecontainer case 2. Therefore, only by changing the depth W of the container case 2', the amount of ink accommodated in the container case 2' can be increased. Incidentally, in FIGS. 16A and 16B, components having the same functions as those in FIGS. 1 and 2 are given the same reference numerals but denoted by a single quotation mark.

供墨口4’和存储装置7’的排列中心，尤其是存储装置7’的电极7a’被设置在距离容器壳体2’表面一预定位置W1的地方即底部，方式与其它墨盒中的一样。也就是说，大容量墨盒1’上供墨口4’的排列中心与容器壳体2’表面的距离W1被设置为等于小容量墨盒1上供墨口4的排列中心与容器壳体2表面的距离W1。同样，大容量墨盒1’上电极7a’的排列中心与容器壳体2’表面的距离W1被设置为等于小容量墨盒1上电极7a的排列中心与容器壳体2表面的距离W1。另外，在表面侧的容器壳体2’上安装有一墨盒识别块70’。因此，墨盒识别块70’位于与其它墨盒相同的位置。The arrangement center of the ink supply port 4' and the storage device 7', especially the electrode 7a' of the storage device 7' is arranged at a predetermined position W1 from the surface of the container casing 2', i.e. the bottom, in the same manner as in other ink cartridges . That is to say, the distance W1 between the arrangement center of the ink supply port 4 ' on the large-capacity ink cartridge 1 ' and the surface of the container casing 2 ' is set to be equal to the arrangement center of theink supply port 4 on the small-capacity ink cartridge 1 and the surface of thecontainer casing 2 The distance W1. Equally, the distance W1 between the arrangement center of the electrodes 7a ' on the large-capacity ink cartridge 1' and the surface of the container housing 2' is set to be equal to the distance W1 between the arrangement center of the electrodes 7a on the small-capacity ink cartridge 1 and the surface of thecontainer housing 2. In addition, an ink cartridge identification block 70' is attached to the container case 2' on the surface side. Therefore, the ink cartridge identification block 70' is located at the same position as the other ink cartridges.

锁紧件5’和6’以与供墨口4’相同的方式位于朝向容器壳体2’表面的一偏置位置以在安装墨盒时确保施加一压力于供墨口4’上。In the same manner as the ink supply port 4', the locking members 5' and 6' are located in a biased position towards the surface of the container housing 2' to ensure that a pressure is applied to the ink supply port 4' when the ink cartridge is installed.

此外，如图16A所示，考虑到可操作性，当用户自滑架上安装或移下墨盒1’时较靠近用户的锁紧件6’的宽度W2优选比锁紧件5’的宽度W3大。即，用户拇指置于其上的锁紧件6’的宽度W2优选比用户食指置于其上的锁紧件5’的宽度W3大。In addition, as shown in FIG. 16A, considering operability, when the user installs or removes the ink cartridge 1' from the carriage, the width W2 of the locking member 6' closer to the user is preferably wider than the width W3 of the lockingmember 5'. big. That is, the width W2 of the locking member 6' on which the user's thumb is placed is preferably larger than the width W3 of the locking member 5' on which the user's index finger is placed.

如图17B所示，一舌部分130a可与一粘结在容器壳体2’上膜57’表面的装饰膜130一起形成，这样舌部分130a就对应于喷墨孔20’和21’的位置(图17A)并封住了喷墨孔20’和21’。As shown in Figure 17B, a tongue portion 130a can be formed with adecorative film 130 bonded to the surface of the film 57' on the container housing 2', so that the tongue portion 130a corresponds to the positions of the ink ejection holes 20' and 21' (FIG. 17A) and seal the ink ejection holes 20' and 21'.

图18表示了如上所述的小容量型墨盒1和大容量型墨盒1’安装到滑架100上的状态。Fig. 18 shows a state where the small-capacity ink cartridge 1 and the large-capacity ink cartridge 1' are mounted on thecarriage 100 as described above.

在上述实施例中，已就一压差阀用作负压产生装置的情形作了说明。但，显然使用一种多孔材料例如一浸渍墨的海绵以通过孔的毛细管力维持负压也能产生相同的效果。In the above embodiments, the description has been made on the case where a differential pressure valve is used as the negative pressure generating means. However, it is evident that the use of a porous material such as an ink-impregnated sponge to maintain a negative pressure through capillary forces through the pores can produce the same effect.

同时，在上述实施例中，构造是这样的，即，使许多墨盒安装于滑架内。或者，可这样构造，即，设置许多滑架并将一个或多个墨盒安装于许多滑架的每一个上。Meanwhile, in the above-described embodiments, the configuration is such that many ink cartridges are mounted in the carriage. Alternatively, it may be constructed such that a plurality of carriages are provided and one or more ink cartridges are mounted on each of the plurality of carriages.

如上所述，根据本发明，可提供一种墨盒，其可拆卸地插入到供墨针内、并安装到可确保与墨盒内存储装置连通的精确位置中。同时，还提供一种墨盒，使用普通的组成部件就能轻易地改变其容量。As described above, according to the present invention, it is possible to provide an ink cartridge which is detachably inserted into an ink supply needle and installed in a precise position ensuring communication with a storage device in the ink cartridge. At the same time, there is also provided an ink cartridge whose capacity can be easily changed using common constituent parts.

如上所述，本发明至少提供如下方案：As mentioned above, the present invention at least provides the following solutions:

(1)一种墨盒包括：具有第一壁的一容器壳体；至少与存储装置相连的至少一电极，该至少一电极相对于壁固定；以及相对于壁可移动的且在Y轴方向高于至少一电极的一接合部分。(1) An ink cartridge includes: a container housing having a first wall; at least one electrode connected to at least the storage device, the at least one electrode being fixed relative to the wall; on a junction portion of at least one electrode.

通过非限制性的实施例，如图2C中所示，一可移动的接合突起5a在Y轴方向高于电极7a。在图2A至2C中所示的实施例中，可移动接合部分是以突起5a为形式的，突起5a形成在以枢转杆为形式的锁紧件5上并与滑架100的凹槽107相接合，但本发明并不限制于此。通过非限制性的实施例，接合部分可形成为锁紧件5内的一凹槽。在这种情况下，滑架100上的配合接合部分优选形成为与凹槽相配合的一突起。By way of non-limiting example, as shown in FIG. 2C, amovable engagement protrusion 5a is higher than the electrode 7a in the Y-axis direction. In the embodiment shown in FIGS. 2A to 2C , the movable engagement portion is in the form of aprotrusion 5 a formed on the lockingmember 5 in the form of a pivot lever and in contact with thegroove 107 of thecarriage 100 . connected, but the present invention is not limited thereto. By way of non-limiting example, the engaging portion can be formed as a groove in the lockingmember 5 . In this case, the fitting engaging portion on thecarriage 100 is preferably formed as a protrusion fitting into the groove.

此外，接合部分可直接形成在容器壳体2的壁上，并不通过锁紧件5。例如，一弹性突起可附着在容器壳体2的壁上作为接合部分。更优选的是，可在容器壳体2的壁上提供一具有圆形末端的弹簧偏压件。在这种情况下，圆形末端依靠弹簧的偏压力自容器壳体2的壁内伸出，这样当与凹槽107相接合时弹簧偏压件提供了一预定的锁紧力将墨盒1固定在滑架100上。在自滑架100插入或移下墨盒1的过程中，由于末端为圆形，圆形末端在弹簧的偏压力的作用下可向容器壳体2内收缩而与凹槽107解除接合。In addition, the engaging portion may be formed directly on the wall of thecontainer body 2 without passing through the lockingmember 5 . For example, an elastic protrusion may be attached to the wall of thecontainer body 2 as the engaging portion. More preferably, a spring bias with rounded ends may be provided on the wall of thecontainer housing 2 . In this case, the rounded end protrudes from the wall of thecontainer housing 2 by means of the biasing force of the spring, so that the spring biasing member provides a predetermined locking force to fix theink cartridge 1 when engaged with thegroove 107. on thecarriage 100 . During the process of inserting or removing theink cartridge 1 from thecarriage 100 , due to the rounded end, the rounded end can shrink into thecontainer housing 2 under the biasing force of the spring to disengage from thegroove 107 .

此外，如图22A和22B所示，一突起131可形成于容器壳体2的一相对坚硬部分上，这样利用至少限定凹槽107的滑架100部分的弹性能将突起131固定到滑架100的凹槽107内。即，利用限定凹槽107的滑架100部分的弹性，使具有突起131的墨盒1能插入、固定到滑架100上以及自滑架100上移下。In addition, as shown in FIGS. 22A and 22B, aprotrusion 131 may be formed on a relatively rigid portion of thecontainer housing 2, such that theprotrusion 131 is fixed to thecarriage 100 by elastic energy of at least the portion of thecarriage 100 defining thegroove 107. In thegroove 107. That is, theink cartridge 1 having theprotrusion 131 can be inserted, fixed to, and removed from thecarriage 100 by utilizing the elasticity of the portion of thecarriage 100 defining thegroove 107 .

(2)在根据(1)构造的一种墨盒内，接合部分与Y轴方向上的至少一电极基本对齐。通过非限制性的实施例，如图2C中所示，接合突起5a与Y轴方向上的电极7a对齐。这种设置明显有助于墨盒1的电极7a与滑架100的电极106之间的可靠接触。(2) In an ink cartridge constructed according to (1), the engagement portion is substantially aligned with at least one electrode in the Y-axis direction.
