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.

[0003]

Therefore, the present invention is intended to propose a novel disk cleaner for a disk cartridge which has not existed in the past. At this time, as the basic configuration of the disc cleaner, like the former disc cleaner, the main body case for accommodating and mounting the disc cartridge to be cleaned, the opening / closing lid for covering the main body case, and the disc surface of the disc cartridge are mounted. The basic configuration is to use a cleaning member to wipe off the dirt on the top. In this case, do not place the disc cartridge on the upper surface of the main body case with its front-back direction reversed. Various design considerations are required. If the disk cartridge is loaded upside down, the head window of the disk cartridge cannot be aligned with the cleaning member, and if this is driven without noticing, the disk cartridge and cleaner will be damaged. This is because the dirt attached to the outer surface of the cartridge is transferred to the cleaning member and easily adheres to the cleaning member, which causes a problem. Also, in such an erroneous loading, the front side having the head window of the disc cartridge is grasped by hand,
There is also a problem that fingerprints and hand marks are easily attached to the disk facing the head window. The present invention has been made in view of this point, and an object thereof is to prevent erroneous loading of a disk cartridge and to prevent contamination of a cleaning member and a disk.

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. 7), and after the half-opening, the opening / closing lid 10 is fully opened by hand.

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, as shown in FIG. 4, 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. Such a cleaning member 16 is located in the inner depth position further in front of the hub receiver 13 at the substantially center on the upper surface 9,
This position is near the pivot joint with the opening / closing lid 10 and the opening / closing lid 1
Since the distance between the lid 10 and the lid 10 is narrowed even when 0 is opened, the cleaning member 16 is relatively hard to reach by hands or other objects than other areas on the upper surface 9, and the cleaning member 16 can be removed by those hands or other objects. You can avoid getting polluted as much as possible. That is,
The opening / closing lid 10 exerts a function as an obstacle for the touch of the cleaning member 16 with a hand or another object.

Next, the disk cartridge D is positioned and mounted on the upper surface 9, and at the time of this mounting, the rear end of the cartridge case 1 (the side without the head window 5) so that the head window 5 corresponds to the cleaning member 16. Since it holds the disc, it is less likely that the disc 3 facing the head window 5 is soiled by the hand. When the disc cartridge D is thus positioned and mounted on the upper surface 9,
As shown in FIG. 1, a hub receiver 13 is inserted into the drive shaft insertion window 4 on the lower surface thereof to receive and support the lower end surface side of the hub 2 of the disk 3, and the cleaning member 16 is pushed into the head window 5. The disc-shaped portion enters and comes into pressure contact with the disc surface of the disc 3 in the radial direction.

Then, when the opening / closing lid 10 is closed, as shown in FIG. 1, the opening / closing lid 10 is automatically closed and locked by the lock lever 35 as shown in FIG.
The disc cartridge D is pressed onto the upper surface 9 by the pressing pin 32 as shown in FIG. Further, the rotary shaft portion 23 on the lid 10 side enters into the drive shaft insertion window 4 on the upper surface side of the disc cartridge D, and the central shaft 26 is fitted into the central hole 13b of the hub receiver 13 to receive the hub 2 from the hub. It is connected to the hub 2 by pressing it horizontally against the body 13. Further, the receiving pad 29 enters the head window 5 on the upper surface side of the disk cartridge D and presses the disk surface of the disk 3 to press and contact the cleaning member 16.

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

[0026]

According to the disk cleaner of the present invention,
Positioning ribs 12, 12 facing each other in the front-rear direction are arranged at front-rear positions on the upper surface 9 with an interval matching the length of the disk cartridge D in the front-rear direction, and a space between the front-side positioning rib 12 and the hub receiver 13 is set. Front end a of disk cartridge D
To the distance L ₁ between the drive shaft insertion window 4 and the rear positioning rib 12 and the hub receiver 13 to the distance L ₂ between the rear end b of the disk cartridge D and the drive shaft insertion window 4. The cleaning members 16 are set together, and the cleaning member 16 is arranged between the positioning rib 12 on the front side and the hub receiver 13. Therefore, it is possible to load the disc cartridge D with the front-back direction correct, and it is possible to prevent damage to the disc cartridge D and the cleaner due to erroneous loading. Also, the disc 3 produced by holding the disc cartridge D in the front-rear direction is reversed. It is also advantageous because it is possible to prevent stains by hands.
