ABSTRACT:
The present invention relates to a magnetic recording/reproducing apparatus. In the magnetic recording/reproducing apparatus, a shutter actuating pin and a locking claw are formed integrally with a rotating member, the rotating member is rotatably supported on a chassis, one end of a torsion coil spring wound around the rotating member is retained by the shutter actuating pin, and a bent portion of the other end of the torsion coil spring is retained by a retainer hole of a holder. Before loading of a disc cartridge, a slide plate is locked by the locking claw at a backward position, so that a holder is maintained at an unloading position, whereas, when the disc cartridge is loaded, the rotating member is rotated by the disc cartridge, so that locking by the locking claw is dismissed to allow the holder to be shifted to a loading position while enabling a shutter of the disc cartridge to be opened by the shutter actuating pin.
