Below, with reference to the description of drawings embodiments of the invention.

The 1st figure and the 2nd figure are side sectional view and the front section view of diagram according to an embodiment of apparatus for mincing file of the present invention.In the drawings,symbol 11 is housing body that the upper end is provided withcharging aperture 12, and in the inside of thishousing body 11, quadrate part forms and is provided with thechopping chamber 14 of chopping withcutter 13 thereon.

Bottom inchopping chamber 14 is provided with discharge opening 15, and will fall and spue through this discharge opening 15 with the chip P ofcutter 13 chopping through chopping, in the lower position of this discharge opening 15, thedebris box 16 of opening above being provided with.

One sidepiece of housing body 11 (being the front sidepiece in the present embodiment) is to be the center with the bottom, and its upper end can be to the switch door 11a that falls near the bodyinclination.Debris box 16 usefulness screws etc. are installed on the internal face of this switch door 11a, make when opening switch door 11a, and the upper end ofdebris box 16 can move on to the outside ofhousing body 11.

Downside at the discharge opening 15 thatshreds chamber 14 is installed with tabular overhead door plate 21, and this overhead door plate can be that open andclose discharge opening 15 is swung in the center with theswinging axle 22 that is hinged on the bottom ofshredding chamber 14.

Overhead door plate 21 among this embodiment is shown in the 3rd figure, it is installed in part bending on theswinging axle 22, make roughly as shape the mountain, the side that the broad face is wherein arranged as the overhead door 21a that closes discharge opening 15 usefulness, is had a side than leptoprosopy in addition as balanced surface 21b.In the end of this balanced surface 21b, be fixed with thecounterweight 23 that the swing position that makes overhead door 21a keeps balance.Again, for the leading section 21c that makes overhead door 21a can swing indebris box 16, overhead door plate 21a should have than the bigger size in interval between the upper end of swingingaxle 22 anddebris box 16.

Form thekink 24 of V font at an end of swingingaxle 22, and permanent magnet 25 is installed at the prolongation axle front end of this kink 24.The top ofV font kink 24 with same form the V font, be fixed on some in two facesflat spring 26, sandwich top 26a on thehousing body 11 and contact combination.For example, also can understand, when overhead door 21a is opening, contact combination, when closing, combine with the following side contacts offlat spring 26 with the upper face side offlat spring 26 from the 1st figure, the 3rd figure.In position, be provided with thereed capsule 27 that the swing position of inspection rollover door 21 is used near permanent magnet 25 again.

With the edge of opening place of chopping with the discharge opening 15 ofcutter 13 quadrature sides, the catch 31 of usefulness of preventing to be scattered hangs down indebris box 16, this catch 31 is in order to prevent in chopping midway, chip is former thereby fly out laterally, be scattering into that the outside ofdebris box 16 uses because of static etc., and its is made with the synthetic resin sheet of for example polyester etc.In the present embodiment, one side catch 31 only the hanging down of the edge of opening of discharge opening 15, but also can all be loaded onto catch 31 at the whole periphery of discharge opening 15.

Again, the symbol M among the 2nd figure is for driving the motor that chopping makes it to rotate withcutter 13.

Below the effect of the present embodiment that just as above constitutes describe.

The 1st figure represents to shred the state of file etc.The quilts such as file that drop into from charging aperture drive the chopping of rotatingcutter 13 choppings by motor M, and its chip P falls downwards by discharge opening 15.At this moment, overhead door plate 21 is shown in the 1st figure, theV font kink 24 of swingingaxle 22 is because the rotatory force thatcounterweight 23 causes and contact combination with the upper side of V fontflat spring 26, and its leading section 21c stops with the heeling condition of predetermined angular on the position in having entered debris box 16.Therefore,, drop on earlier on the overhead door 21a, on overhead door 21a, slide again, fall in thedebris box 16 by the chip P of discharge opening 15.

Like this, when overhead door plate 21 was in the state thatdischarge opening 15 is opened, the permanent magnet 25 that is installed in the prolongation shaft end of swingingaxle 22 madereed capsule 27 remain on the state of " ON ", and the running of apparatus for mincing file is proceeded.

Chip P in falling intodebris box 16 increases, its upper end P.When reaching the high position of leading section 21c than overhead door 21a, chip P is just difficult to be slipped down from overhead door 21a, and gradually near the front end 21c of overhead door 21a accumulation get up.When the weight of the chip P on being deposited in overhead door 21a and the weight sum of overhead door 21a surpassed the weight sum ofcounterweight 23 and balanced surface 21b, overhead door plate 21 was promptly swung to direction shown in the arrow (counterclockwise) in the 1st figure.Because 21 swing among this embodiment, the permanent magnet 25 that is installed in the prolongation shaft end of swingingaxle 22 also moves, and makesreed capsule 27 be in " OFF " state.So the running of apparatus for mincing file stops, sending the signal thatdebris box 16 has been filled simultaneously.

About indebris box 16, taking out the method that chip P discards, describe with reference to Fig. 4.At first, to close body layback (being the left side among the figure), making switch door 11a is that fulcrum is swung with the bottom the upper end of the switch door 11a that is in closed condition (state of the 1st figure).When switch door 11a moves on to position shown in the Y of the 4th figure, the leading section 21c of overhead door 21a is upwards pushed away by the topinboard end 16a ofdebris box 16, because this effect that upwards pushes away, promptly by makingflat spring 26 strains cross the top 26a offlat spring 26, swing turns to the downside offlat spring 26 to theV font kink 24 that forms on the prolongation axle of the swingingaxle 22 of overhead door plate 21.In asingle day kink 24 crosses the top offlat spring 26, because the effect ofcounterweight 23, monoblock overhead door plate 21 promptly further rotates to clockwise direction (with reference to the 1st figure, the 4th figure), and overhead door 21a closes discharge opening 15.Switch door 11a can reach position shown in the Z, by suitable means, and chain (not shown) for example, the position that keeps it to open by switch door 11a andhousing body 11 are coupled together.In the position of this Z, the upper opening ofdebris box 16 is in the state that can be fetched into fully outside thehousing body 11, can be discarded from taking-up chip P in the debris box 16.The taking-up of this chip P is reclaimed with bag (vinyl bag etc.) and can be carried out easily if be equipped with in advance in thedebris box 16.

Between the discarded operational period of the taking-up of carrying out this chip, because discharge opening 15 closed by overhead door 21a, so even the chips of staying in thechopping chamber 14 fall, chip can not fallen outside thechopping chamber 14 yet, can not scatter in housing body 11.In addition, taking outdebris box 16, cleaninghousing body 11 when inner,, do not injured withcutter 13 by chopping so hand can not stretch in thechopping chamber 14 mistakenly because discharge opening 15 closed by overhead door 21a.

After the discarded end of chip, close the action of switch door 11a.When switch door 11a swings to the position (the 4th figure) of X from the position of Z, the top ofdebris box 16inboard end 16a contacts with the balanced surface 21b of overhead door plate 21, if make switch door 11a further to the direction swing of closing, balanced surface 21b is promoted by the top ofdebris box 16inboard end 16a, shakes to counter clockwise direction.Because this wobbling action Yi Bian Vfont kink 24 makesflat spring 26 strains, moves on to the upper side offlat spring 26 Yi Bian cross the top 26a offlat spring 26, contact combination with upper side owing to the weight of counterweight 23.Like this, as mentioned above, overhead door plate 21 keeps tilting with discharge opening 15 opened state.

After switch door 11a closed fully, push the running switch once more, apparatus for mincing file just restarts running.

Like this,, can close the overhead door plate of discharge opening 15, so the chips that remain in thechopping chamber 14 can not be scattered in thehousing body 11 when taking out chip because be equipped with in the time of to open discharge opening 15, taking-up chip when shredding according to present embodiment.In addition, because the variation of swing position that can be by detecting overhead door plate 21 predicts the state that chip is filled,, can make this a part of designs simplification of below of choppingchamber 14 again so also can checkout gear be set specially.Have again, because predicting of this chip is to be undertaken by the leading section 21c swing of stretching into the overhead door 21a in thedebris box 16 is moved, so, can predict before the upper end-face edge ofdebris box 16 in talus accumulation, can what also leave taking-up and debris under the vacant state on the top of debris box 16.Therefore, the taking-up of chip becomes easily, meanwhile, can prevent that the part chip is scattered indebris box 16 outsides.

The 5th figure to the 8 figure illustrate other embodiment of the present invention.

In this embodiment, comparing with the device among the aforesaid embodiment, only is the shape and the mounting structure difference thereof of overhead door plate, and other all are same structures, so use identical symbol, omit its explanation simultaneously.

In this embodiment, one becomes tabularoverhead door plate 41 by hanging down on theswinging axle 42 that its upper end-face edge 41a is arranged at with being installed in horizontal direction the below of shredding chamber 14.In addition, the bottom of overhead door plate 41 (leading section) 41b is arranged to stretch in thedebris box 16, can carries out the structure that chip detects.Swingingaxle 42 is provided with rotatablely, simultaneously, forms switch motion bar 44 on the one end.In addition, near this switch motion bar 44, sense switch (for example microswitch) 45 is being set.

In the back side ofoverhead door plate 41 side, be provided with the overheaddoor pressure bar 43 that roughly becomes the L font, its method to set up is as follows: a 43a of limit portion wherein is along the upper end-face edge 41a ofoverhead door plate 41, and the 43b of its another limit portion is towards the direction that is orthogonal with upper end-face edge 41a.This overheaddoor pressure bar 43 is installed on thehousing body 11 swingably, and meanwhile, the end of the onebar limit 43a of portion is connected withextension spring 47, so that the 43b of another limit portion rotates to the direction of overhead door plate 41.The first end parts of the 43b of another limit portion bends under situation about keeping with upper end-face edge 41a orthogonal direction again, this part that is bent as with the upper end-face edge ofdebris box 16 near the debrisbox contact site 43c that contacts.

In this embodiment, in the chopping running, shown in the 5th figure,overhead door plate 41 lets droop, and its leading section 41b stretches within thedebris box 16, and meanwhile,discharge opening 15 is being opened.Under this state, switch motion bar 44 contacts withsense switch 45, and the chopping running is proceeded.

Chip P falls in thedebris box 16 by discharge opening 15 fromchopping chamber 14, whendebris box 16 is filled, because the upper end P of chip P₀Effect, the leading section 41b ofoverhead door plate 41 is pushed, in the 5th figure to swing counterclockwise.Because the swing of thisoverhead door plate 41,sense switch 45 is cut off, and the running of apparatus for mincing file stops, and meanwhile, sends the signal that chip has been filled.

On the other hand, when carrying out above-mentioned chopping running, overheaddoor pressure bar 43 forces its debrisbox contact site 43c to contact with the upper end-face edge ofdebris box 16 owing to be subjected to the pulling force of spring 47.Because the contact action of this debrisbox contact site 43c, the assigned position in the casingmain body 11 is fixed and remained in to debris box 16.Again becausedebris box 16 is mounted and fixed on the switch door 11a, so switch door 11a also keeps and closes state.

Then,, shown in the 8th figure, open switch door 11a, make the upper opening ofdebris box 16 move to the outside of casingmain body 11 take out chips and discarded occasion from debris box 16.When switch door 11a is opened to Y position among the 8th figure, the debrisbox contact site 43c of overheaddoor pressure bar 43 and the upper end-face edge ofdebris box 16 are thrown off, and contact with the upper rear (inboard portion) ofdebris box 16, on the direction in the outside ofdebris box 16 being shifted onto casingmain body 11, work.Also have, the leading section 41b ofoverhead door plate 41 then is forced to cross the upper end-face edge ofdebris box 16, and swing is moved up.

11a reaches the state that stops behind the Z position at the switch door, the debrisbox contact site 43c of overheaddoor pressure bar 43 anddebris box 16 are thrown off fully, further swing to the top position owing to the effect ofspring 47, the back side ofoverhead door plate 41 is upwards pushed away, makeoverhead door plate 41 keep closing the position of discharge opening 15.Like this, can prevent that the chip that remains in thechopping chamber 14 from falling and being scattered in the casingmain body 11 from discharge opening 15.

In the occasion of closing switch door 11a, interlock therewith also carries out the opening operation of overhead door plate 41.At first, in the time of near switch door 11a is closed to the Y position, by inboard, the upper end portion ofdebris box 16, the debrisbox contact site 43c of overheaddoor pressure bar 43 is pushed, the pulling force of overheaddoor pressure bar 43antagonistic springs 47 and to swing counterclockwise.When switch door 11a was closed the position of roughly closing, the debrisbox contact site 43c of overheaddoor pressure bar 43 contacted with the upper end-face edge ofdebris box 16 once more, by the pulling force ofspring 47 it is pushed down downwards.In addition,overhead door plate 41 is also swung in overheaddoor pressure bar 43 swing, hangs down under its leading section 41b stretches into state in the debris box 16.Meanwhile,sense switch 45 begins action.

According to present embodiment, it is simple that the structure ofoverhead door plate 41 can be done than aforesaid embodiment.Because discharge opening 15 is wide-open, so when chopping, chip collides withoverhead door plate 41 hardly, the adjustment ratio of chip detection position is easier to again.In addition, because the leading section 41b ofoverhead door plate 41 is deeper stretched in thedebris box 16, so can carry out the detection of chip with timing more early.

In addition, under switch door 11a closing state, because overheaddoor pressure bar 43 plays a part thefixing debris box 16 of pushing, so even not as in the past, the mechanism of latch switch door 11a is set in addition, blocking that also can maintained switch door 11a.

Again, in the embodiment of above explanation, as the introduction of switch door be to be the device of such mechanism of toppling over of fulcrum with its bottom, but this switch door also can be as what use in the past, use to horizontal switch.In addition, introduced debris box has been fixed on example on the switch door, but also can make this debris box and switch door independent separately, and debris box has been arranged in the housing body.

Also have, as the debris box sense switch, the above-mentioned example of having introduced with reed capsule, microswitch, but also can use other various switches, for example optoelectronic switch etc.

Again, the timing of the switch motion of overhead door plate, position that can be by changing the balanced surface 21b contact with the top edge of debris box or debrisbox contact site 43c and shape wait to be adjusted.In addition, the switch motion of overhead door plate, also can make it with the taking-up of debris box action interlock, and with the switch motion interlock of door.

The 9th figure to the 12 figure are illustrated to be a example according to the switching mechanism of the switch door 11a of apparatus for mincing file of the present invention.Switch door 11a is provided with to such an extent that can be fulcrum with the bottom, and upper portion is to swinging near the open and close of body side, anddebris box 16 is installed in the inboard of switch door 11a.Stop in the switch angle of regulation in order to get out of the way the 11a that closes the door, between switch door 11a andhousing 11, be provided withchain 51 andkeeper 52,alignment pin 53 is installed on thehousing 11.

The 11st figure is the expanded view of the 9th figure XI part, the swing fulcrum of diagram switch door 11a.Switch door 11a is fixing supporting member 54 in its bottom, and by chimeric with support rod 55 rotationally this supporting member 54, making switch door 11a can be that fulcrum carries out the switch swing with support rod 55.In addition, on supporting member 54, from the front face side of switch door 11a, towards with the direction of switch door 11a quadrature,form breach 56, utilize thisbreach 56, support rod 55 is carried out handling operation relatively.

The 12nd figure is the expanded view of part shown in the 9th figure XII of detent mechanism of release position of diagram limit switch door 11a.The front end ofchain 51 is equipped withkeeper 52, on thiskeeper 52, is respectively equipped with diameter than big installinghole 57 of the head ofalignment pin 53 and thefixing hole 58 57 that link to each other with this installing hole, that diameter is littler than the head ofalignment pin 53.

When discarding operation, be fulcrum with the bottom to opening at first, bychain 51 and be located at thekeeper 52 ofchain 51 ends, switch door 11a stopped swinging in the switch angle of regulation near the body side oscillation switch door 11a.Shown in the 13rd figure, thedebris bag 59 that vinyl is made is provided with to such an extent that tightly be attached to the inner surface ofdebris box 16, and chip P is raised by the space betweenhousing 11 and switch door 11a withdebris bag 59, moves the outside to.Then,new debris bag 59 is shut switch door 11a from putting into the inner face ofdebris box 16 betweenhousing 11 and the switch door 11a, the discarded end of job.As mentioned above, because be to be fulcrum with the bottom to opening near the body side oscillation by switch door 11a, take out of chip P with the form of debris bag one by one, discard operation, be easy to so discard operation, working space can be littler.And in discarded operation, chip can not overfill fromdebris box 16 yet, disperses to the inside ofhousing 11 and on every side.

When being necessary to clean the inside ofhousing 11, move thekeeper 52 of the 12nd figure earlier a little, installinghole 57 is aimed at alignment pin 53.Then,keeper 52 to the 13rd figure arrow T₁Direction moves, and extracts from alignment pin 53.Then, make the inboard be provided with the switch door 11a ofdebris box 16 to swinging inclination significantly near the body side.The bottom structure of switch door 11a is shown in the 11st figure, and the occasion (occasion of the solid line of the 11st figure) when the switch angle of the switch door 11a angle of inclination during for discarded operation can not be extracted supporting member 54 (the 11st figure arrow L on support rod 55₁), but, can extract (the 11st figure arrow L to supporting member 54 from support rod 55 in the occasion that tilts significantly to the body side (occasion of the 11st figure double dot dash line)₂).Therefore, if switch door 11a is tilted significantly to the body side, supporting member 54 is extracted from support rod 55,11a unloads fromhousing 11 the switch door, can easily clean the inside ofhousing 11.

In the above-described embodiment, be not described, below illustrate fordebris bag 59 being fixed in thedebris box 16 and an example of the pressure bagging apparatus that uses for the fixing means of thedebris bag 59 that is contained indebris box 16 inside.

The 14th figure is the local oblique view that diagram is contained in pressure bagging apparatus one embodiment of thedebris bag 59 in the debris box 16.What as shown in the figure, metal wire was made is roughly]framework 60 of font is installed on the debris box 16.Thisframework 60 bends respectively by top portion 61, a pair of side portion 62a and 62b and the front end of this 62a of opposite side portion and 62b and a pair of kink 63a and the 63b that form constitute.This occasion, make a pair of kink 63a offramework 60 and 63b against with the outside wall surface of the switch door 11a opposition side ofdebris box 16, under the state offramework 60 separate support, be installed in the top of the outside wall surface of thisdebris box 16 by brake component 64.Thisframework 60 can be a fulcrum with brake component 64, to direction (the 14th figure arrow T of switch door 11a₃Direction) swing can be lived debris box just like surround like thedebris box 16 embedding from the top.The length of the top portion 61 of framework 60 (the 14th figure L₃) than lateral length (the 14th figure L of debris box 16₅) long, length (the 14th figure L between a pair of kink 63a offramework 60 and the two ends of 63b₄) than lateral length (the 14th figure L of debris box 16₅) short.On the top portion 61 offramework 60 and a pair of kink 63a and the 63b, be equipped withdebris bag 59 press be attached to use on thedebris box 16 push rubber 65.The 15th figure is the side sectional view of illustratedframe 60 when being embedded on the debris box 16.Substantially be close to thedebris bag 59 that is collected indebris box 16 inboards, its upper section turns back in the outside wall surface of debris box 16.The part of turning back to the outside wall surface ofdebris box 16 in thedebris bag 59, be clamped between the outside wall surface of theframework 60 that is embedded on thedebris box 16 anddebris box 16 and push between the outside wall surface of rubber anddebris box 16,debris bag 59 is fixed on the debris box 16.The 16th figure is the side sectional view of the chimeric discharged occasion of illustratedframe 60 and debris box 16.In the 16th figure, switch door 11a stops in the switch angle of regulation owing to the effect ofchain 51 to the body side oscillation.Because length (the 14th figure L between the two ends of a pair of kink 63a offramework 60 and 63b₄) than lateral length (the 14th figure L of debris box 16₅) short, so kink 63a by makingframework 60 and 63b against the outside wall surface ofdebris box 16, are provided withframework 60 with the state of separate support.If press bagging apparatus that the operation thatdebris bag 59 is fixed indebris box 16 is described to using, then at first, under turn back the state ofdebris box 16 outside wall surface on the top ofdebris bag 59,debris bag 59 is contained in thedebris box 16, with brake component 64 is fulcrum,framework 60 to switch door 11a side (the 14th figure arrow T₃Direction) swing makes it be embedded in the top ofdebris box 16.

After doing like this, the part that is folded back the outside wall surface ofdebris box 16 in the debris bag promptly is sandwiched between the outside wall surface of pushingrubber 65 anddebris box 16 and between the outside wall surface offramework 60 anddebris box 16, is firmly fixed.After the chopping end of job, shown in the 16th figure, in case open switch door 11a, remove the chimeric of 60 pairs ofdebris box 16 of framework,framework 60 promptly can bend towards upper portion housing 11 sides and keep the separate support state, so, form very big space betweenframework 60 and the switch door 11a, can carry out loading, unloading operation easily with respect to thedebris bag 59 ofdebris box 16.

The 17th figure is that diagram is sent the side sectional view that instruction makes the structure that drives theshift knob 70 that shreds the motor M forward or reverse of usingcutter 13.

As shown in the figure,shift knob 70 can be that swing at the center with thefulcrum 71 of the substantial middle bottom that is located atshift knob 70.

In a side's of shift knob 70 a side, for example below the 71a that just changes one's position, be provided with theswitch 72 of just migrating near shift knob 71a, in the front end bottom of the 71a that just changes one's position of shift knob, be provided with thelock pawl mechanism 73 of just migrating again.In case live the front end of the 71a that just changes one's position of shift knob with theselock pawl mechanism 73 structures of just migrating, can switch 72 perseverations of just migrating down with the back side of the 71a that just changes one's position of shift knob.Like this, in the occasion that theswitch 72 of just migrating carries out work,shift knob 70 becomes just the changing one's position state of the position of the switch of maintenance.

The opposing party's of shift knob 70 a side is for example stopping and the bottom of the side 71b that reverses, near stopping and the side 71b that reverse of shift knob, being provided withcounter-rotating usefulness switch 74, again in the counter-rotating of shift knob with stop the leading section of side 71b, is provided with stationary positioned rubber 75.By compressing this stationary positionedrubber 75, can be with the stopping and the back side of the side 71b that reverses of shift knob, making counter-rotating withswitch 74 actions.In the occasion of reversing and carrying out work withswitch 74, shiftknob 70 tilts towards the state of the counter-rotating side position of the switch in this wise.Any all discontiguous occasion at the back side ofshift knob 70 with justmigrate switch 72 orreversal switch 74,shift knob 70 is in the state of the shutdown switch position of approximate horizontal.

If the surface of the 71a that just changes one's position of push switch button, the leading section of the 71a that just changes one's position of shift knob promptly hooks in thelock pawl mechanism 73 of just migrating, promptly shown in the 18th figure, in the state that becomes the position of the switch of just changing one's position, theswitch 72 of just migrating drops into action to shift knob 70.By motor M, chopping is just being changeed with cutter 13.The file that is dropped into from chargingaperture 12 etc. enters chopping with between thecutter 13, is become chip by chopping continuously, falls to be stored in thedebris box 16.

The occasion that this document shredding mechanism is stopped, stopping and the surface of the side 71b that reverses of push switch button, the leading section of the 71a that just changes one's position of shift knob is thrown off with thelock pawl mechanism 73 of just migrating,shift knob 70 is become make and justmigrate switch 72 and counter-rotating, motor M is stopped with the state of any shutdown switch position of all being failure to actuate of switch 74.As long as stopping and the power on the surface of the side 71b that reverses of this occasion push switch button is because with the power of the size that the leading section of shift knob 71a and thelock pawl mechanism 73 of just migrating are thrown off, so need not be with big power.In addition, when shift knob is in the state of shutdown switch position, because stationary positionedrubber 75 is supportingshift knob 70, so can easily makeshift knob 70 keep the state of approximate horizontal.

In the occasion that makes the counter-rotating of this document shredding mechanism owing to reasons such as paper obstructions, stopping and the surface of the side 71b that reverses of push switch button, make and be located at stopping and stationary positionedrubber 75 compressions of the front end of the side 71b that reverses of shift knob, with stopping and the reverse side of the side 71b that reverses of shift knob, making counter-rotating withswitch 74 actions (the 19th figure).Motor M counter-rotating thus, file etc. by from chopping with spuing the cutter 13.Stopping and the power on the surface of the side 71b that reverses of this occasion push switch button, requirement is the power that can compress the sort of size of stationary positionedrubber 75.

As mentioned above, in order to makeshift knob 70 become the state of the counter-rotating side position of the switch, must have and to compress stationary positionedrubber 75 such big power, so, when the state that makesshift knob 70 from the position of the switch of just changing one's position becomes the state of shutdown switch position, can not makeshift knob 70 swing to the state of the counter-rotating side position of the switch mistakenly.Therefore, motor M can not reverse and make chopping produce unnecessary abrasion or produce kinetic equation loss with cutter.In addition, become the operating physical force of the state usefulness of the counter-rotating side position of the switch, can easily adjust as long as change the elastic force of stationary positioned rubber for makingshift knob 70.

As described above, the apparatus for mincing file that the present invention is related to because be provided with the overhead door plate of the discharge opening of switch chopping chamber, so take out and during debris, can not allow remain in the indoor chip of chopping and be scattered in the housing body.Again, when the cleaning housing body was inner, it was indoor and injured to prevent that the handle mistake from stretching into chopping.

In addition,, its leading section is stretched in the debris box,, when debris box takes out, can under debris box has living space the situation in leeway, carry out chip so can detect with timing early because dual-purpose overhead door plate carries out the detection of chip.Like this, just can not allow around chip is scattered in, can be rapidly and carry out the discarded operation of chip easily.
