<p>A cartridge body (10) storing an optical disc (12) has a disc inlet/outlet port (14) for taking in and out the disc. A lid member (11) is mounted on the cartridge body to be rotatable between a closed position and an opened position. The lid member has a pair of guide rails (18, 19) extending from the lid member into the cartridge body and facing the surfaces of the disc. Each guide rail has a guide hole (18a, 19a). The cartridge body has guide grooves (34a, 34b) in which the guide rails slid, and a guide pin (20) slidably inserted into the guide holes of the guide rails. During the opening and closing operation of the lid member, the guide grooves and guide pin guides the guide rails. <IMAGE></p> |
