Abstract
A recording and/or reproducing apparatus includes a cartridge receiving holder, a cartridge shutter opening device for opening a laterally slideable shutter of a disc cartridge along with insertion thereof into the holder, a mount base displaceable between a retracted position away from the holder and an operative position in which a head and spindle motor mounted on the base will be made operative with respect to a disc contained in the full-loaded disc cartridge in the holder. The disc cartridge is retained in the full-loaded position in the holder through engagement between a lock lever rotatably mounted on the holder and a notch formed on the side periphery of the disc cartridge. The lock lever is normally biased by a spring to direct outwardly so that the disc cartridge is free from contract with the lock lever during insertion into the holder. When the disc cartridge has reached the full-loaded position, a sliding plate is sprung back toward a direction opposite to the cartridge inserting direction, upon which the lock lever is actuated and then the mount base is shifted to the operative position.
