ABSTRACT OF THE DISCLOSURE A case for a disc-shaped recording medium operates together with a disc-shaped recording medium reproducing appa- ratus 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 releas- ing mechanism provided at the innermost part of the disc-shaped recording medium reproducing apparatus opposite to the insert- ing 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 repro- ducing apparatus together with 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 pre- determined position within the jacket. The engagement releas- ing 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 inser- tion 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.
