Abstract: A case for a disc-shaped recording medium operates together with a disc-shaped recording medium reproducing apparatus provided with an inserting opening through which the case is inserted, a turntable for rotating the disc-shaped recording medium, and locking mechanism and engagement releasing mechanism provided at the innermost part of the disc-shaped recording medium reproducing apparatus opposite to the inserting opening with respect to 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 closing member inserted through the opening of the jacket for closing the opening of said jacket. The closing member unitarily has a pair of engaging arms on both sides thereof which can elastically bend. The closing member is locked by the locking mechanism upon insertion into the innermost part of the reproducing apparatus together wtih the jacket.

Abstract: A rotary recording medium reproducing apparatus reproduces a rotary recording medium accommodated within a case where the case comprises a jacket provided with a space for accommodating the rotary recording medium and an opening for allowing the rotary recording medium to go in and out of the jacket, and a lid member inserted through the opening of the jacket for closing the opening of the jacket.

Abstract: A reproducing apparatus reproduces a loaded disc-shaped recording medium derived from a case. The case comprises a jacket which has a space for accomodating 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 member inserted through the opening of the jacket for closing the opening of the jacket.

Abstract: 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.
