Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk cleaner having a special mechanical characteristic for removing dirt on a disk of a disk cartridge.

[0002]

2. Description of the Related Art Heretofore, there is no disk cleaner having such a special mechanical character.

[0003]

In recent years, this type of disk cartridge has a disk, which is a recording medium such as a magnetic disk or an optical disk, rotatably built in a cartridge case. For example, in a cartridge case for a magnetic recording disk, A cleaning liner made of non-woven fabric or the like is attached to the inner surface of the disc to remove dirt such as dust adhering to the disc.

However, since the cartridge case has a head window, and a part of the disc surface is exposed from this window, fingers of the hand touch the disc through the head window during handling, and fingerprints and stains are left on the disc. It adheres strongly to the board surface and is easy to get dirty. When the head window has a dedicated shutter for opening and closing the head window like a 3 inch or 3.5 inch disk cartridge, the dirt is prevented by the shutter, but it is simplified because the shutter is not provided. Also, in the case of disc cartridges, such as those for computer games, stains such as hand marks tend to adhere strongly when not in use.

Even if the disc cartridge is equipped with a shutter, although it is not directly contaminated by fingertips, etc., it is a dust trap in the contaminated air that enters when the shutter is opened while the disc drive is being driven, in particular, the shape of a cigarette tar. There is a case where the disc surface of the disc is fogged due to being soiled by the sticky substance.

The dirt strongly adhered to the surface of the disc is loaded by loading the disc cartridge into the disc drive, rotating the disc by the motor on the drive side, and slidingly contacting the cleaning liner in the cartridge case. Although it is possible to drop the minutes, it is difficult to remove them sufficiently, which causes dropouts and the like. Further, when the head on the disk drive side is a contact type, dirt on the disk is transferred to and adheres to the head on the drive side and stains the head, which causes dropout and the like. In addition, it is almost impossible to clean a disk cartridge of a type that does not have a cleaning liner.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a disk cleaner capable of simply and quickly removing dirt on the disk before and after loading the disk cartridge into the disk drive. Is. Another object of the present invention is to prevent dust and the like in the air from entering through the head window of the disk cartridge and adhering to the disk during cleaning.

The push-out pad 29 is incorporated in the boss portion 30 of the lower side wall 23b so as to be freely movable in the vertical direction orthogonal to the longitudinal direction of the cleaning material 20. In addition, the upper and lower side walls 23a and 23b are provided with a receiving portion 31 that elastically abuts a part of the upper surface of the cleaning material 20, and a roller insertion port 33 that a part of the circumference of a feed roller 32, which will be described later, faces. They are provided so as to face each other between the outlets 25.

As the cleaning material 20, for example, a product name PALPAS manufactured by Fuji Bow Ehime Co., Ltd., which is made of a porous urethane film, has a strong surface and is worn away.
It is particularly recommended in that it has a napped portion that withstands hair loss, etc., and exerts the effect of adsorbing fine particles.

(Cleaning Material Feeding Roller) In FIG. 3, a feed roller 32 is supported by a roller shaft 46 in the recess 22 of the main body case 8, and a dial 47 is attached to one end of the shaft 46. When the cleaning cartridge 21 is accommodated in the recess 22, the feed roller 32 faces the roller loading port 33 as shown in FIG. 7, and sandwiches the cleaning material 20 with the receiving portion 31 in the cartridge case 23. It is like this. Feed roller 32 with dial 47
Is rotated by a predetermined angle, the cleaning material 20 is sequentially sent out toward the outlet 25 by a predetermined length.

(Cleaning Material Pushing Mechanism) In FIGS. 1 to 4, inside the main body case 8, the pushing pad 29 of the cleaning cartridge 21 is operated to move the cleaning material 20 into the head window 5 of the disk cartridge D. A cleaning material pushing mechanism 34 for pushing in the direction is incorporated. The cleaning material push-out mechanism 34 is used for the cleaning material 20 during cleaning.
Faces the head window 5 through the extrusion pad 29 and presses against the disk 3 so that the cleaning material 20 is separated from the disk 3 when not in use and not used for cleaning.

Specifically, it is assumed that the push-out pad 29 moves up and down in association with the opening / closing operation of the lid 10. That is,
As shown in FIGS. 1 and 3, the base portion of the pad lever 35 is pivotally attached to the inside of the main body case 8 by a shaft 36 so that the pad lever 35 can swing up and down around the shaft 36. The upward pin 37 provided at the tip is located below the recess 38 provided at the lower end of the extrusion pad 29. Between the pad lever 35 and the inner bottom surface of the main body case 8, a push-up spring 3 for biasing the pad lever 35 to swing upward is provided.

On the shaft 41 of the pad lever cam 40, a cam spring 44 is mounted which urges the cam 40 to rotate in the direction of arrow A so that the operation pin 42 projects from the hole 43. A cam follower 45 protruding from the pad lever 35 is brought into contact with the peripheral surface of the pad lever cam 40. A receiving pad 48 is mounted on the lid body 10 side so as to face above the push-out pad 29.

Thus, as shown in FIGS. 4 and 6,
When the lid 10 is opened, the cam spring 44 causes the arrow A
The cam follower 45 is pushed down by the pad lever cam 40 that is urged to rotate in the direction, and the pad lever 35 swings downward around the shaft 36 against the push-up spring 39, so that the pin 37 at the tip of the push pad 29 is pushed. The push-up force of the push-out pad 29 is released by removing it downward from the recess 38. Therefore, the push pad 29 is lowered by its own weight, and the pushing action of the cleaning material 20 is released. With this release, the cleaning material 20 is retained in the extrusion port 28 by the tension or the feeding by the feeding roller 32, and retracts into the mounting surface 9.

As shown in FIG. 5, when the disk cartridge D is mounted on the mounting surface 9 and the lid 10 is closed, the operating pin 42 is pushed down by the lid 10 and the pad lever cam 40 is rotated. Around 41, the cam follower 45 is rotated in the direction opposite to the direction of arrow A, the pushing force of the cam follower 45 is released, the cam follower 45 rolls upward on the circumferential surface of the cam 40, and the pad lever 35 rotates around the shaft 36. It swings upward, the pin 37 at the tip is put in the recess 38 of the push pad 29, and the pad 29 is pushed up. With this pad 29,
As shown in FIG. 1, the cleaning material 20 projects from the extrusion port 28 onto the mounting surface 9, enters the head window 5 of the disk cartridge D, and contacts the disk 3.

[0025]

According to the present invention, the disk 3 of the disk cartridge D mounted on the mounting surface 9 of the main body case 8 is rotated by the driving means 14 and the cleaning material 20 removes the dirt attached thereto. Therefore, before loading the disc cartridge D into the disc drive or after use, the disc 3 can be cleaned easily and quickly, and the head on the drive side can be prevented from being contaminated. There is an advantage. In particular, according to the present invention, by covering the head window 5 of the disk cartridge D mounted and mounted on the mounting surface 9 of the main body case 8 with the lid 10, dust in the air can be removed even during cleaning. Since it is possible to prevent the disk 3 from being rotationally exposed from the window 5 in sequence, the cleaning effect can be further enhanced.
