Abstract
PURPOSE:To eliminate a limit switch by providing a friction idle running means in a part of the precise driving structure of a pickup. CONSTITUTION:At the time of the shift of the optical pickup 100, the friction idle running means 60 in the precise driving structure 400 is in a frictional state, and driving force from a driving source is securely transmitted to the optical pickup 100. If the optical pickup 100 shifts to a prescribed position on the other hand, the friction idle running means 60 starts idle running, and the shift of the optical pickup 100 stops even if the driving source of the precise driving structure 400 drives. Thus, the optical pickup 100 can precisely be stopped in the prescribed position and the elimination of the limit switch for positioning and the like is attained.
