Abstract
It is an object of the present invention to provide an improved disc changer adapted to exactly detect whether a magazine storing a plurality of discs has been attached in the disc changer. When a magazine storing a plurality of discs is inserted into the disc changer, a detection arm and a lock arm both serving as moving members are moved by such an insertion. The lock arm, by virtue of the movement of itself, engages into an insertion groove provided on the backside of the inserted magazine and locks the magazine on the disc changer. The detection arm, by virtue of the movement of itself, actuates a lock detection switch. Here, since the detection arm and the lock arm are both urged by an urging spring, it becomes possible to exactly detect the attachment of the magazine by allowing the moving members locking the magazine on the disc changer to actuate the lock detection switch.
