ABSTRACT:
A cartridge-holder locking device for a magnetooptical disk player includes a biasing device for elastically biasing a cartridge holder in the open, cartridge insertion/withdrawal position, a locking pin fixed to the cartridge holder, and a locking/releasing device installed at a position of the deck corresponding to the locking pin for locking and releasing the locking pin. The locking device includes a slide plate with locking piece, a solenoid, and a spring. The spring biases the slide plate and locking piece to engage the locking pin and hold the cartridge holder in the loaded, ready to play, position. Upon actuation, the solenoid overcomes the bias of the spring to move the slide plate and locking piece away from the locked position to permit the cartridge holder to move to the open position.
