装置。 It consists of a locking part that is fixed to the laser pick-up, and an operating member that is fixed to the body. a pair of articulated arms extending inward through the spring pieces, and a free end of the articulated arms positioned midway between the spring pieces and connected via each hinge part and engaged with the locking part. The operating rod is provided with an engaging portion that engages with the lever, and the operating rod is constantly subjected to the elasticity of the spring piece via the articulated arm to select either an extended posture or a contracted posture, and the engaging portion is engaged with the operating rod. A locking device for a laser pickup in a compact disc player, which is configured to be freely engaged with a locking portion, thereby restraining the movement of the laser pickup, and releasing the laser pickup.
