BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk cleaner for removing dirt on the disk of a disk cartridge in which a disk as a recording medium is rotatably incorporated in a cartridge case.

[0002]

2. Description of the Related Art Conventionally, a disk cleaner having a special mechanical property for removing dirt on a board surface of a digital audio disk (product name compact disk) in which the disk is not housed in a protective cartridge case is used.
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 present applicant has previously proposed a disk cleaner having a special character that can easily and quickly remove a dirty disk in a disk cartridge (for example, Japanese Patent Application No. 60-2.
86149). There, the disc cartridge D is placed on the upper surface 9 of the main body case 8 as shown in FIG.
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, and the disk 3 is rotated to wipe off the dirt on the disk 3.

[0003]

However, in the above-mentioned disc cleaner, the disc cartridge D has the rear end portion P.
Is placed on the upper surface 9 so as to project rearward of the main body case 8, and a part of the rear end side of the disc cartridge D is pressed and supported by the opening / closing lid 10. According to this, since the protruding end portion P of the disc cartridge D can be easily grasped by hand when the disc cartridge D is taken in and out, the disc cartridge D can be easily taken in and out. However, since the upper surface 9 of the main body case 8 lacks horizontal support by the amount of the protrusion of the rear end portion P of the disc cartridge D, the parallelism for keeping the disc cartridge D horizontal during cleaning is lowered, and becomes unstable, and thus becomes horizontal. In addition to being unable to rotate, the hand may touch the protruding end P of the disc cartridge D during cleaning, which may move the disc cartridge D. Further, the upper surface of the cartridge case 1 is pressed and fixed by the entire length of the rear side wall 10a of the opening / closing lid 10 over the entire length in the left-right direction. However, if the opening / closing lid 10 is excessively pressed, the cartridge case 1 is flexibly deformed and the disc 3 is rotated. It will cause trouble. An object of the present invention has been made in view of such a point, and is to surely prevent movement and vibration of a disk cartridge during cleaning. Another object of the present invention is to enable a disk cartridge to be supported and fixed without adversely affecting the disk.

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.

As shown in FIGS. 4 and 5, the opening / closing lid 10
Is closed, the tip of the engaged piece 34 slides on the taper 36a of the engaging claw 36 of the lock lever 35 to slightly swing the lever 35 around the shaft 39, and then the engaging claw 36 is inserted into the recess 34a. 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.

In order to open the opening / closing lid 10, as shown in FIG. 9, put a finger in the recess 38 of the main body case 8 to lock the lock lever 3.
When the operating portion 37 of 5 is pushed down against the spring 40, the lever 35 swings around the shaft 39 to disengage the engaging claw 36 from the recess 34a of the engaged piece 34, and the push-up pin 43 presses the pin. By pushing up the protrusion 45, the opening / closing lid 10 is forcibly pushed open to the half-opened state (see FIG. 6).

Next, the procedure for cleaning the disk 3 of the disk cartridge D will be described. Open / close lid 1
When 0 is opened and the cleaning cartridge 14 is accommodated in the recess 15 of the main body case 8, a part of the cleaning member 16 is pushed upward by the pushing protrusion 17 from the pushing port 21 of the cartridge case 18, as shown in FIG.

Next, when the disk cartridge D is positioned and mounted on the upper surface 9, as shown in FIG. 7, the hub receiver 13 is inserted into the drive shaft insertion window 4 on the lower surface side thereof, and the lower end surface of the hub 2 of the disk 3 is inserted. It receives and supports the side, and the extruded portion of the cleaning member 16 enters the head window 5 and presses and contacts in the radial direction of the disk surface of the disk 3.

Thereafter, when the opening / closing lid 10 is closed, as shown in FIG. 7, the opening / closing lid 10 is automatically closed and locked by the lock lever 35 as described above.
As shown in FIG. 5, the rear corner portion of the disc cartridge D is pressed against the receiving portion 46 by the pressing member 32. In this state, a slight gap S is formed between the upper surface 9 of the main body case 8 and the disc cartridge D as shown in FIG. Further, the rotary shaft portion 23 on the lid 10 side enters the drive shaft insertion window 4 on the upper surface side of the disk cartridge D, and the central shaft 26 is fitted into the central hole 13b of the hub receiver 13 to connect the hub 2 to the hub. It is connected to the hub 2 by pressing it horizontally against the receiving body 13. In addition, the receiving pad 29,
Head window 5 on the top side of the disk cartridge D
When it enters the inside, the disk surface of the disk 3 is pressed and brought into pressure contact with the cleaning member 16. At this time, the rear corner of the disk cartridge D is sandwiched and supported between the pressing member 32 and the receiving portion 46, but the front side thereof is restricted by the pressing member 32 'on the front side to prevent the floating.

Thus, as shown in FIG. 10, when the fingertip is inserted into the recess 24a of the manual handle 24 and the manual handle 24 is horizontally rotated around the rotary shaft portion 23 on the lid 10, the rotary shaft portion 23 rotates. Then, when the eccentric shaft 27 reaches the drive hole 7 of the hub 2, as shown in FIG.
The disk 3 is rotated by the force of the spring 28. The dirt attached to the surface of the disk 3 as the disk 3 rotates is wiped off by the cleaning member 16.

At this time, the disc cartridge D is fixed by pressing the rear corner of the cartridge case 1 against the receiving portion 46 by the pressing member 32, so that the disc 3 rotates in the cartridge case 1 while undulating. Even if the rotating shaft 23 is vibrated or is vibrated, it does not float or dance on the upper surface 9, and the alignment of the head window 5 with the extrusion protrusion 17 and the receiving pad 29 can be secured. , Its cartridge case 1
The disk 3 can be stably rotated in the inside. In addition, even if there is a backlash between the front and rear positioning ribs 12 and the front and rear ends of the disc cartridge D, a state of being fixed at a fixed position can be secured. Further, unlike the central portion having a space for rotatably accommodating the disk 3, the rear corner portion of the cartridge case 1 is near the intersection of adjacent peripheral side walls and has a high rigidity with respect to the load. However, the cartridge case 1 can be pressed and fixed without bending, and the rotation of the disk 3 is not adversely affected. Further, since the opening / closing lid 10 is closed and locked, it does not accidentally open, and the connection state between the rotating shaft portion 23 and the hub 2 and the contact state between the disc 3 and the cleaning member 16 are reliably held. In addition, the operating portion 37 of the lock lever 35 is present in the recess 38, and
Since it is located inside the outer shell of the body, even if the open / close lid 10 and the main body case 8 are supported by the hand opposite to the hand holding the manual handle 24, the hand may accidentally touch the operating portion 37 by mistake. Even in this respect, accidental opening of the opening / closing lid 10 can be prevented, and cleaning can be safely performed.

After cleaning, the disk cartridge D
In order to take out the lock lever 35, the operation portion 37 of the lock lever 35 is pushed down by a hand which is inserted from the recess 38, the engaging claw 36 of the lever 35 is disengaged from the engaged piece 34 on the opening / closing lid 10 side, and the push-up pin 43 is used. The opening / closing lid 10 is forcibly pushed upward in a half-open state. The unlocked state can be confirmed by this half-opening, and then the opening / closing lid 10 in the half-opened state.
The disk cartridge D can be taken out by easily opening the disk.

[0028]

As described above, according to the disk cleaner of the present invention, the cartridge case 1 is in the closed state.
A portion of the outer surface outside the outer periphery of the disk 3 is pressed against the receiving portion 46 of the upper surface 9 of the main body case 8 by the pressing member 32 provided on the inner surface side of the opening / closing lid 10. Therefore, at the same time when the opening / closing lid 10 is closed, the fixed state of the disk cartridge D is obtained, and when the opening / closing lid 10 is opened, the pressing action is released, so that the opening / closing lid 10 does not require any special fixing operation and releasing operation. It is convenient to handle as it can be opened and closed. Further, the disk cartridge D does not move or vibrate during cleaning, and the disk 3 can be stably rotated in the cartridge case 1 for cleaning. Since the outer portion of the outer surface of the cartridge case 1 is pressed from the outer periphery of the disk 3, the cartridge case 1 is not deformed and the rotation of the disk 3 is not hindered. Since the portion outside the outer periphery of the cartridge 3 has a high case strength, the cartridge case 1 is not deformed by the pressing load.
