[Industrial applications]

 The present invention relates to a cleaning device for cleaning a disc contained in a cartridge or the like.

[0002]

[Prior art]

 Generally, a magneto-optical disk has been used as a recording medium used in OA equipment and the like because of its large storage capacity. This magneto-optical disk is housed in a box-shaped cartridge like a floppy disk. A type has been developed in which only a part of the magnetic disk is exposed through the window only when recording / reproducing information. By the way, this type of magneto-optical disc (MD: Magneto-Optical Disc) has a relatively large diameter, unlike a floppy disc or the like, and regularly or irregularly removes dust and the like from the disc surface. I need to do some cleaning. In this type of cleaning device, the playback device itself has a cleaning mode, and by turning on this cleaning mode, the cleaner head is brought into contact with the disc surface from below, instead of the playback pick-up. It is conceivable to perform a cleaning operation.

[0003]

[Problems to be solved by the device]

 However, the provision of the cleaning mechanism in the reproducing apparatus set as described above has a problem that the apparatus itself becomes large and complicated, resulting in high cost. In order to solve this, it is possible to insert a finger into the window of the cartridge and rotate the magneto-optical disk with this finger to clean the disk surface with a cloth, but unlike the floppy disk, the magneto-optical disk itself. Since the disk has a relatively large diameter and a large weight, it is not easy to rotate the disk itself, and it takes a relatively long time to clean the entire surface of the disk, which is not realistic. The present invention has been made in view of the above problems and was devised in order to solve them effectively. The purpose of the present invention is to perform a cleaning device for a magneto-optical disk that can easily perform a cleaning operation manually. To provide.

【Example】

 Hereinafter, an embodiment of a cleaning device for a disk according to the present invention will be described in detail with reference to the accompanying drawings. 1 is a perspective view showing an embodiment of a cleaning device for a disk according to the present invention, FIG. 2 is an exploded perspective view of the cleaning device shown in FIG. 1, and FIG. 3 is a perspective view showing the disk. First, a disk device to be cleaned by the cleaning device of the present invention will be described with reference to FIG. In this embodiment, an optical disc device will be described as an example of the disc device. The magneto-optical disk device 1 has a general structure similar to that of an ordinary floppy disk, but the magneto-optical disk 2 itself is hard and has a large diameter, and the opening / closing shutter 3 is provided with an opening / closing spring or the like. This is different from the floppy disk in that this opening / closing operation is performed manually. That is, the magneto-optical disc 2 is formed by vapor-depositing a recording layer or the like on a transparent substrate made of a hard resin or the like having a relatively large diameter, and its central portion has a motor shaft or the like when it is rotated. A metal boss 4 is provided to be engaged with. The magneto-optical disk 2 is housed in a box-shaped cartridge 5 made of plastic or the like, and a pickup (not shown) is provided on one side of the cartridge 5 for recording / reproducing information. Is formed with a window portion 6 for approaching the disk 2, and an opening / closing shutter 3 for manually opening and closing the window portion 6 is slidably provided in the window portion 6.

A central hole 7 is formed in the center of the cartridge 5 so that the metal boss 4 faces the outside. In order to clean the recording surface of the magneto-optical disk 2 of the magneto-optical disk device 1 thus constructed, the disk cleaning device of the present invention is used. As shown in FIGS. 1 and 2, the cleaning device 8 has a disc-shaped dummy turntable 9 slightly larger than the diameter of the metal boss 4 of the disc 2, and at the center lower end thereof. Is formed by slightly advancing downward in the drawing, for example, a magnet or the like, so that the metal boss 4 of the disk 2 can be adsorbed and temporarily fixed.

The dummy turntable 9 is integrally connected to a thick knob portion 12 via a connecting shaft 11, and the outer peripheral surface of the knob portion 12 is prevented from falling off so that it can be easily grasped. The uneven portion 13 is formed. Therefore, by gripping the knob portion 12 and rotating it while the metal boss 4 of the disc is adsorbed to the adsorption portion 10, only the disc 2 in the cartridge 5 can be rotated. On the other hand, the connecting shaft 11 is provided with an arm portion 14 having a length such that its tip reaches the window portion 6. Specifically, the arm portion 14 is made of, for example, a metal plate or the like having a certain degree of elasticity, and an insertion hole 15 slightly larger than the diameter of the connecting shaft 11 is formed at the base end thereof. By inserting the connecting shaft 11 into the insertion hole 15, the arm portion 14 is rotatably and loosely supported by the connecting shaft 11.

The arm portion 14 is tilted slightly downward in the figure, and its tip is horizontal so as to be parallel to the disk surface. A cleaning pad 16 made of, for example, a sea line member or having flocked is formed on the lower surface of the tip of the arm portion 14, that is, the surface facing the disk, and this portion contacts the disk surface. Configured to get. The length L 1 of the cleaning pad 16 in the disc radial direction is preferably set to be equal to the length L2 of the recording portion of the disc 1 exposed in the window 6 in the radial direction so that the entire circumference of the recording portion can be cleaned. Constitute.

Next, the operation of this embodiment configured as described above will be described. First, as shown in FIG. 4, the cleaning device 8 is turned upside down by gripping the knob portion 12 by hand, and when the cleaning pad 16 provided at the tip of the arm portion 14 is subjected to wet cleaning, for example, alcohol or the like is used. The cleaning liquid 17 containing a volatile liquid, an antistatic liquid, etc. is absorbed in an appropriate amount, or no cleaning liquid is absorbed when performing dry cleaning, and the cleaning operation is performed. At this time, the opening / closing shutter 3 provided in the cartridge 5 of the magneto-optical disk device 1 is slid to expose the disk 2 to the window 6 in advance (see FIG. 3).

In this state, the cleaning device 8 is turned upside down and attached to the magneto-optical disk device 1 as shown in FIG. At this time, the attracting portion 10 composed of the magnet of the cleaning device 8 attracts the metal boss 4 of the disc 2 to temporarily fix the entire disc. The cleaning pad 16 at the tip of the arm portion 14 elastically abuts the recording surface of the disk 2 exposed in the window portion 6 by the action of the arm portion 14. At this time, since the length of the cleaning pad 16 is sufficiently long, the cleaning pad 16 crosses the ring-shaped recording surface of the disk 2 and comes into contact with the entire area. By rotating the knob portion 12 with the disk 2 sucked and held in this manner, the disk 2 is integrally rotated in the cartridge 5, while the cleaning pad 16 provided on the arm portion 14 has a window portion. Since it remains at 6, the disk 2 rotates relative to the cleaning pad 16, and the dust and the like adhering to the surface thereof is wiped off for cleaning.

As described above, according to this embodiment, the entire circumference of the disk can be cleaned by the cleaning pad 16 by adsorbing the metal boss 4 at the center of the disk 2 and rotating the entire disk. Further, since the dummy turntable 9 functions to regulate the suction angle of the cleaning device so that the dummy turntable 9 becomes parallel to the disc 2 when the disc is attracted, no surface wobbling occurs when the disc rotates. Further, since the arm portion 14 is elastically bendable, it is possible to perform cleaning without damaging the disc without fear of applying excessive stress to the disc surface during cleaning. In the above embodiment, a permanent magnet is used for the attraction unit 10, but the present invention is not limited to this, and a vacuum attraction disk or the like may be used instead of this. Further, although the magneto-optical disk has been described in the above embodiments, the present invention is not limited to this, and it goes without saying that the invention can be applied to other disks such as an optical disk and a magnetic disk.
