JPS63298763A - Cleaner for disk carrier roller - Google Patents

Abstract

PURPOSE:To attain sure cleaning onto the surface of a loading roller through having only to apply the loading operation by forming the titled cleaner with a shape in response to the shape of the loading roller and making it of a material at least having the surface elasticity and softness. CONSTITUTION:A cleaning disk 20 having a shape and size able to be interposed between loading rollers 11 and 12, with a center hole 22 similar to that of a disk provided at the center, is formed. The loading rollers 11, 12 are cleaned by loading the cleaning disk 20 made of a soft material at least whose surface has an elasticity. Thus, a foreign material or dust adhered to the loading roller is removed by simple operation.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a cleaner for disk transport rollers, and more particularly to a cleaning device suitable for a loading device equipped with a pair of loading rollers.

[Conventional technology]

A disc player, typically a CD player, is equipped with a loading device that automatically loads discs.
In this loading device, a pair of loading rollers sandwich a disk and the loading rollers are driven and rotated to load the disk into a player.

[Problems to be solved by the invention]

The above-mentioned loading device for a disc player uses a pair of loading rollers to sandwich and feed the disc with a constant pressure, so if there is hard dust on the loading roller, it may cause the disc to be pressed against the disc during loading. There was a problem that it would leave marks. Particularly, in in-vehicle CD players, etc., not only dirt and dust but also foreign matter from the outside often adhere to the loading roller, which may cause the disc to drop out.

[Means to solve the problem]

Therefore, this invention aims to eliminate foreign matter and dust attached to the loading roller in the loading device of a disc player.
Furthermore, it is intended to be able to remove static electricity with a simple operation, and for this purpose, it is a disk of a shape and size that can be introduced between loading rollers, and the center hole is similar to the center hole of the disk. The present invention is characterized in that a cleaning disk provided with holes is formed, and the loading roller is cleaned by loading this cleaning disk, which has at least an elastic and soft surface.

【Example】

Examples of this invention are attached below. In Figure 0, which will be explained along with the drawings, reference numerals 11.12 indicate a pair of loading rollers, and both loading rollers 11.12 are symmetrically tapered with a minimum diameter at the center and a maximum diameter at both ends. It has a disc feeding function and is located inside the player's loading slot. A cleaning disk 20 that can pass between the loading rollers 11 and 12 is prepared. (the shape of an abacus bead), and a circular stepped portion 21 larger than the diameter of the player's mochi clamper 1 is provided on both sides at the center. A center hole 22 having the same diameter is formed. At least the surface of the cleaning disk 20 is made of an elastic and soft material such as cloth or foam, and can be impregnated with a cleaning liquid. Therefore, when cleaning the loading roller 11.12, the cleaning disc 20 can simply be pushed into the loading slot and comes into contact with the loading roller 11.12 of a player with an automatic loading function. During this loading process, foreign matter and dust are removed from the surfaces of the rotating rollers 11 and 12. In addition, by forming it from a conductive material, it may be used as a static electricity removing device for the loading rollers 11 and 12. The player itself clamps the cleaning disc 20 and enters the play mode, but since it cannot pick up the signal, it determines that the disc is a dropout disc and ejects the cleaning disc. In the case of the loading rollers 11 and 12, a disk-shaped cleaning disk of equal thickness is used. Further, by making a window hole 23 in the cleaning disk 20 and providing a blade 24 therein and rotating it after loading, it is possible to blow away and remove dust from the inside of the mechanism and the pickup unit. Effects of the Invention 1 As is clear from the above description, the disk transport roller cleaner of the present invention has a shape corresponding to the shape of the loading roller, and at least the surface is made of an elastic and soft material. By simply performing a loading operation on the player, the surface of the loading roller can be reliably cleaned, and marks on the disc can be prevented.
