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. The engaging arms and the jacket have a slipping out preventing engaging part for preventing the closing member from slipping out the jacket in a state where the closing member is inserted into a predetermined position within the jacket. The engagement releasing mechanism has engagement releasing members which relatively make contact with and push against sloping surfaces of the engaging arms for bending the engaging arms inwards, upon insertion of the closing member into the innermost part of the reproducing apparatus together with the jacket. The engaging arms and the engagement releasing members have a deviation preventing engaging part at least at a part where the engaging arms and the engagement releasing members respectively make contact, for preventing deviation within a plane perpendicular to a plane in which the closing member extends.
