Therefore, according to the optical pickup cleaning mechanism of the present invention, when the optical pickup cleaning mechanism is mounted on the reproducing device and rotated,
Due to the surface pressure of the elastic member against a large amount of dust accumulated in the lens of the optical pickup, the tar of the cigarette, etc., and the rotation of the disk causes the porous elastic member such as a sponge to press and release the lens. By the suction action by the repeated operation, the surface of the pickup lens can be repeatedly pressed and wiped off sequentially. Further, since the disc does not use a special disc and the cleaning of the lens of the optical pickup is repeated at high speed at the beginning of the first reading operation of the recorded information, the cleaning is completed, so that the cleaning time can be shortened.
