Pre-recorded cartridge video/audio disk

A case for a disc-shaped recording medium is used in a disc-shaped recording medium reproducing apparatus provided with an insertion opening through which the case is inserted, a turntable for rotating the disc-shaped recording medium, a lid plate locking member and a disc-shaped recording medium clamping member provided at the innermost part of the disc-shaped recording medium reproducing apparatus opposite to the inserting opening with respect to the turntable, and a jacket opening enlarging member provided in the vicinity of the insertion opening, capable of moving between the position in the vicinity of the insertion opening and the innermost part of the disc-shaped recording medium reproducing apparatus above the turntable. 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.

Case for a disc-shaped recording medium

A reproducing apparatus reproduces a disc-shaped recording medium which is accommodated within a case comprising jacket which has 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 reproducing apparatus comprises an inserting opening through which the case is inserted a lid plate locking mechanism and disc-shaped recording medium clamping mechanism respectively provided at the innermost part of the reproducing apparatus opposite to the inserting opening with respect to a turntable, for rotating the disc-shaped recording medium, and a jacket opening enlarging mechanism provided in the vicinity of the inserting opening, capable of moving over the turntable between the position in the vicinity of the inserting opening and the innermost part of the reproducing apparatus. The jacket opening enlarging mechanism has an enlarging member for enlarging the opening of the jacket by entering inside the cutouts of the lid plate, upon insertion of the jacket into the reproducing apparatus through the inserting opening. The lid plate locking mechanism has a locking member for locking the lid plate by entering inside the cutouts of the lid plate, upon insertion of the lid plate into the innermost part of the reproducing apparatus together with the jacket. The disc-shaped recording medium clamping mechanism has a clamping member for clamping the disc-shaped recording medium within the jacket by riding over the ride-over part of the lid plate and entering through the enlarged opening of the jacket, upon insertion of the lid plate into the innermost part of the reproducing apparatus together with the jacket.
