ABSTRACT:
In a disc playback device in which a disc cartridge case housing a disc is loaded in a disc cartridge case holder of a main body of the device and this holder is moved from a disc non-playback position to a disc playback position for playing back of the disc, a loading system for a disc cartridge case comprises a curved surface portion formed in a corner portion on the side of the disc cartridge case from which the case is inserted into the holder and an uncurved surface portion formed in a corner portion on the side opposite to the side from which the case is inserted into the holder. A case erroneous insertion blocking member having an engaging portion is provided on the holder. If the case in its correct insertion posture is inserted into the holder, the engaging portion of the blocking member cooperates with the curved surface portion of the case to permit the case to be inserted into the holder. If the case in an incorrect insertion posture is about to be inserted into the holder, the engaging portion of the blocking member cooperates with the uncurved portion of the case to prevent the case from being inserted into the inside of the holder.
