Abstract
A recording/reproducing device including a cam which permits a cartridge holder to descend and assume a loaded state, a lock for locking the cam so as to hold the cartridge holder in the lock state before loading, and a detector for detecting that a disc cartridge has been inserted up to a predetermined position in the cartridge holder. The locked state of the cam is released upon detection of proper insertion of the cartridge, thereby allowing the cartridge holder to descend until it assumes the loaded state. Unless the disc cartridge is inserted in the predetermined position in the cartridge holder, the cartridge holder cannot assume the loaded state, thus permitting the recording/reproducing device to be used always in a normal condition.
