Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a cleaner for compact disks, etc.

Conventional Technology Conventional analog records have sound grooves on the surface, and dust adheres to these grooves, causing noise. Therefore, the contact portion for cleaning was designed to remove dust along the groove and was rotated along the groove.

Problems that the invention aims to solve: In order to remove dust attached to a disk with a smooth surface such as a compact disk, it is not possible to simply rotate the contact part for cleaning on the surface of the disk. It can only be removed. Further, dust that simply moves without adhering remains on the surface of the disk when the contact portion is removed. Furthermore, dust attached to the contact area has the risk of causing concentric scratches on the disk surface, and especially on digitally recorded optical discs, these concentric scratches can exceed the signal reading error correction range and cause errors. There is a drawback that it occurs and cannot be reproduced.

Means for solving the problem: A self-propelled device that rotates around the circumference of the disk by providing a fulcrum at approximately the center of the disk, and a self-propelled device that rotates around the circumference of the disk around the fulcrum, and a self-propelled device that rotates around the disk around the fulcrum, and a self-propelled device that rotates the disk around the center of the disk. The cleaning device includes a contact portion for cleaning toward the outer periphery and a drive device for moving the contact portion.

Function: The self-propelled device rotates around the disk while the contact portion removes dust toward the outer circumference of the disk.

Example An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of the present invention, and FIG. 2 is a sectional view of the main parts.

A disk 1 is placed on a flat plate, and a fixing device 3 having a center spindle 2 is placed in the center hole 1a of the disk 1. A cleaner 4 that rotates by itself around a center spindle 2 receives electric power from a battery 5 as a power source to rotate a motor 6. The motor 6 drives the self-propelled idler 7 to rotate it approximately in the tangential direction of the disk 1. A belt 10 is attached to an inner belt pulley 8 and an outer belt pulley 9 with flocked hair 10a so as to cover a portion corresponding to the recording signal section 1b of the disk 1.
are coupled to be driven by a motor 6.

The belt 10 connects the pulleys 8 and 9 while contacting the surface of the disk 1 from the center to the outer circumference.
Pause. Rotate in the direction of arrow A.

Operation When the cleaner 4 of the present invention is placed on the disk and the switch 11 is turned on, the motor 6 rotates to rotate the self-propelled idler 7 and the belt pulley 9.

The self-propelled idler 7 moves along the outer periphery of the disk 1, while the belt pulley 9 moves the belt 10 from the center of the disk 1 in the direction of the outer periphery arrow A while contacting the belt 10. Dust attached to the surface of the disk 1 is pushed out toward the outer circumference of the disk 1 by the flocks 10a of the belt 10. The cleaner 4 rotates the surface of the disk 1 around the center spindle 2 by a self-propelled idler. The center spindle 2 may be provided in advance on a flat plate on which the disk is placed. Further, in the above embodiment, the cleaner 4 is self-propelled, but the disk may be rotated.

Effects of the Invention According to the present invention, since the cleaning is performed from the center of the disk toward the outer circumference, dust is sent outside the recording area, and no concentric scratches are created on the recording area, thereby reducing the generation of noise.
