ABSTRACT:
A loading unit for a disc cartridge includes a cartridge holder movably supported relative to a chassis. The cartridge holder is moved towards a recording and/or reproducing device for recording and/or reproducing information signals on or from a recording medium housed within the disc cartridge. The cartridge holder is configured to hold the disc cartridge inserted therein and has an engaging recess and an insertion detector. The insertion detector is moved in response to the disc cartridge being inserted into the cartridge holder. A stop mounted on the cartridge holder has a retention portion for retention by the chassis and an engaging protrusion for engagement with the engaging recess of the disc cartridge. The stop is slidingly contacted with the chassis in conjunction with movement of the cartridge holder towards the recording and/or reproducing device. The stop is inhibited from movement by the insertion detector when a disc cartridge is not inserted into the cartridge holder and the retention portion is engaged by the chassis. The stop is released from inhibition of movement when the disc cartridge is inserted into the cartridge holder and the insertion detector is moved, thereby disengaging the retention portion from the chassis, whereby the stop engages the engaging protrusion with the engaging recess in the disc cartridge.
