Claims

[Scope of Claim for Utility Model Registration] A turntable is arranged downward above a tray on which a disk is placed, a clamper moves upward, the disk is pushed up from the tray and clamped to the turntable, and an optical pick-up is performed. The disc player is configured such that the disc is moved under the disc to play the disc, a clamper moves down, the disc is unclamped, and the disc is lowered and placed on the tray, the optical pick-up a mover movable between a first position corresponding to the standby position of the optical pickup and a second position beyond the inner circumferential position of the disk within the movement range of the optical pickup; a spring member that biases the slider in the direction of the second position; a mechanism that moves the slider to the second position against the spring member prior to playback of the disk; When the disc is locked in position and the disc clamped to the turntable is removed from the disc player, or when the power to the disc player is cut off, the lock mechanism is activated to release the lock. When released, the mover returns to the first position by the spring member, and during the return, the mover locks the optical pick-up and pushes the optical pick-up back to the standby position. player.
