The case comprises a jacket having a space for accommodating the disc-shaped recording medium and an opening for allowing the disc-shaped recording medium to go in and out of the jacket, and a lid plate inserted through the opening of the jacket for closing the opening of the jacket. The lid plate has cutouts wherein the jacket opening enlarging member and the lid plate locking member enter. The opening of the jacket is enlarged by the jacket opening enlarging member within the cutouts of the lid plate upon insertion of the jacket inside the reproducing apparatus through the insertion opening. The lid plate is locked by the lid plate locking member within the cutouts of the lid plate upon insertion into the innermost part of the reproducing apparatus together with the jacket. The lid plate further has a ride-over part for to allowing the disc-shaped recording medium clamping member to ride over said lid plate and enter from the enlarged opening of the jacket and clamp the disc-shaped recording medium inside the jacket upon insertion of the lid plate into the innermost part of the reproducing apparatus together with the jacket. The jacket is pulled out in an empty state leaving behind the lid plate locked by the lid plate locking member and the disc-shaped recording medium clamped by the disc-shaped recording medium clamping member, when the jacket is pulled out from within the reproducing apparatus in a direction opposite to the direction of the insertion.
