2. Description of the Related Art In a CD player, an objective lens of an optical pickup for optically reading a disk signal is always exposed, so that dust and the like in the atmosphere may adhere to the object and become dirty. If such contamination becomes remarkable, the quality of the reproduced signal is adversely affected, such as skipping of sound, noise, and deterioration of sound quality. Therefore, from the viewpoint of always maintaining the cleanliness of the surface of the objective lens at a certain level or more and maintaining the quality of the reproduced signal,
Various lens cleaners have been developed and put into practical use.

[0003] Among such lens cleaners, a disk type lens cleaner having a cleaning member such as a brush provided on one surface of a disk having the same specifications as a compact disk (hereinafter abbreviated as CD) has a simple structure. Because it is easy to use, it is widely used. FIGS. 6 and 7 are views showing a conventional example of such a lens cleaner. Among them, the lens cleaner shown in FIG. 6 has the flocking brushes 2 arranged at two locations close to each other in the radial direction of the disc 1. The lens cleaner shown in FIG. 7 has flocking brushes 2 distributed in a spiral manner at eight locations in the circumferential direction on the inner peripheral side of the disk 1 so as to gradually move away from the center of the disk 1. is there.

[0006] These lens cleaners shown in FIGS. 6 and 7, like a normal CD, insert a disc into a CD player, transport the disc to a reading position, and then perform a normal reading operation by the mechanism of the apparatus, that is, a normal reading operation. The objective lens is cleaned by using the operation of the optical pickup in the disk radial direction and the rotation of the disk 1. That is, the flocking brush 2 and the objective lens are aligned by the operation of the optical pickup in the radial direction of the disk, and the flocking brush 2 is moved in contact with the objective lens by the rotation of the disk 1 so as to adhere to the objective lens.
