Claims

[Claims for Utility Model Registration] An optical disc player that uses one pick-up device to read signals embedded on both sides of the disc, wherein both ends of the pick-up device are rotatably connected to a movable piece, and the pick-up device is connected to the movable piece. A feeding mechanism is installed to move the lens in the radial direction of the disk, and when the objective lens of the pick-up device is located on the outer circumferential side of the disk, the pick-up device is reversed and the objective lens is directed from one surface of the disk to the other surface. An optical disc player characterized in that a means is provided.
