Claims

[Scope of Claim for Utility Model Registration] In a disk player equipped with a disk clamp mechanism in which a clamp arm having a disk clamper is moved between a clamp position and a clamp release position by a motor via a gear mechanism, the clamp arm is released from the clamp. a spring member that biases the disc to the desired position; a clutch mechanism provided in the gear mechanism; and a clamp release operation mechanism that is operated when attempting to unclamp the disc when the disc player is in a non-energized state. The disc player has a clutch release mechanism that releases the clutch mechanism when the clamp release operation mechanism is operated, and a mechanism that locks the clamp release operation mechanism so that it cannot be operated when the disc player is energized. When the clamp release operation mechanism is operated when the disk player is in a non-energized state, the clutch release mechanism is operated, the clutch mechanism is released, and the clamp arm is moved to the clamp release position by the spring member. Configuration disk player.
