For example, Japanese Utility Model Publication No. 59-168878 and 59-1.
It is publicly known in the publication such as 73192. However, there is no disc cleaner having a special mechanical characteristic for removing dirt on a disc, for example, in a disc cartridge for computer games, that is, a disc cartridge in which a disc is housed in a protective cartridge case. Therefore, the applicant of the present invention has previously proposed a disk cleaner having a special mechanical property that can easily and quickly remove a dirty disk in a disk cartridge (for example, Japanese Patent Application No. 60-
286149). There, as shown in FIG. 13, the disk cartridge D is placed on the upper surface 9 of the main body case 8, and the cleaning member 16 provided on the main body case 8 side is pressed against the disk 3 facing the head window 5 of the disk cartridge D. The disk 3 is brought into contact with the disk 3 and is rotated to wipe off dirt on the disk 3.

を目的とする。However, in the above-mentioned disc cleaner, the disc cartridge D is placed on the upper surface 9 so that the rear end portion of the disc cartridge D projects from the main body case 8 toward the front rear side, and the cartridge case is opened and closed by the opening / closing lid 10. The upper surface of the rear end portion of 1 is pressed and supported. However, at the front end of the disk cartridge D, the upper and lower surfaces of the disk 3 facing the head window 5 are sandwiched by the pressing pad 29 and the cleaning member 16, but the front end of the cartridge case 1 is simply placed on the upper surface 9. I just put it. Therefore, when rotating the disk 3 during cleaning, the front end of the cartridge case 1 is likely to vertically vibrate, which hinders horizontal rotation of the disk 3 and uneven cleaning by the cleaning member 16 is likely to occur. In particular, if the plastic opening / closing lid 10 or the cartridge case 1 is deformed such as warped or twisted, especially in a high temperature environment, even if the dimension is slightly varied, the front end portion of the cartridge case 1 is cleaned at the time of cleaning as described above. There is a problem that rattling is likely to occur. The present invention has been made paying attention to such a point, and the vibration of the disk cartridge D during cleaning does not adversely affect the rotation of the disk 3.
The purpose is to prevent it surely. Another object of the present invention is to effectively suppress vertical vibration of the cartridge case 1 even when the opening / closing lid 10 and the cartridge case 1 are slightly deformed.

2 is just above the receiving portion 12a, that is, the pressing member 3
When 2 and the receiving portion 12a are arranged so as to face each other on the same line of action, when the forces F1 and F2 are applied to the front and rear of the receiving portion 12a of the cartridge case 1, the cartridge case 1 alternates up and down from the receiving portion 12a. Since the movement is allowed, the effect of suppressing the vertical vibration of the cartridge case 1 is small. However, as described above, the pressing member 32 and the receiving portion 12a are
Are displaced from each other in the front-rear direction, the movement of the cartridge case 1 alternately moving up and down in the front-rear direction relative to the receiving portion 12a can be well regulated by the cooperation of the pressing member 32 and the receiving portion 12a. Vibration can be effectively suppressed.

The opening means is provided with an opening 47 in a part of the upper surface of the rear positioning rib 12 on the upper surface 9 of the main body case 8 and the push-up pin 43 is incorporated in the opening 47 by a spring 44 so as to constantly push the push-up pin 43 upward. On the other hand, a pin pressing protrusion 45 is provided on the inner surface of the opening / closing lid 10 so as to face the push-up pin 43. When the opening / closing lid 10 is completely closed, the pin pressing protrusion 45 causes the push-up pin 43 to spring 44.
I try to push it down against. Push-up pin 4 above
3 has a collar 43a at its intermediate portion, and this collar 43a abuts against the lower end of the opening 47 to prevent the push-up pin 43 from being pushed further up by the spring 44, so that the tip of the push-up pin 43 is fixed. The positioning rib 12 does not protrude from the upper surface. This prevents the disk 3 from touching the tip of the push-up pin 43 and being damaged when the disk 3 is attached or detached.

At the same time as obtaining the closed lock state to engage, the pin pressing protrusion 45 on the side of the opening / closing lid 10 causes the push-up pin 43 to spring 44.
The push-up pin 43 opens and closes the lid 1
The state where 0 is pushed open and biased is obtained.

クリーニングを行える。At this time, in the disk cartridge D, the four corners of the cartridge case 1 are attached to the upper surface 9 by the pressing member 32.
Since the disk 3 is pressed against and fixed to the upper side, the disk 3 may float or dance on the upper surface 9 even if the disk 3 rotates in a swelling manner in the cartridge case 1 or receives vibration of the rotating shaft portion 23. In this case, the disk 3 can be stably rotated in the cartridge case 1. In particular, the front pressing member 32 and the receiving portion 12a
Since the cartridge is displaced from the front and the rear, it is possible to effectively prevent the cartridge case 1 from moving up and down due to vibration. The four corners of the cartridge case 1 are also highly rigid with respect to the load, so that the cartridge case 1 can be pressed and fixed without bending, and the rotation of the disk 3 is not adversely affected. Also, the opening / closing lid 1
Since 0 is closed and locked, it does not open accidentally,
The state where the rotary shaft portion 23 and the hub 2 are connected, and the disc 3
The contact state between the cleaning member 16 and the cleaning member 16 is reliably maintained, and the operating portion 37 of the lock lever 35 is located inside the recess 38 and inside the outer casing of the main body case 8. Even if the open / close lid 10 and the main body case 8 are supported by the hand opposite to the holding hand, the hand will not accidentally touch the operating portion 37 accidentally.
Also in this respect, it is possible to prevent the opening / closing lid 10 from being opened accidentally and to perform cleaning safely.

A receiving portion 12a for receiving and a pressing member 3 for pressing the upper surface side of the above-mentioned portion of the cartridge case 1.
The two are provided so as to be displaced from each other in the front-rear direction. Therefore,
Since the movement of the cartridge case 1 alternately moving up and down in front of and behind the receiving portion 12a can be well regulated by the cooperative action of the pressing member 32 and the receiving portion 12a, the vertical vibration of the cartridge case 1 can be effectively suppressed, and the cartridge case 1 The disk 3 can be stably rotated in the inside for cleaning.
