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. The rotary recording medium reproducing apparatus comprises an inserting opening through which the case is inserted, a turntable for rotating the rotary recording medium, a lid member locking mechanism and rotary recording medium clamping mechanism respectively provided at an innermost part of the reproducing apparatus opposite to the inserting opening with respect to the turntable, a jacket opening enlarging mechanism provided in the vicinity of the inserting opening, capable of moving over the turntable between a position in the vicinity of the inserting opening and the innermost part of the reproducing apparatus, in response to an operation in which the case is inserted into and pulled out from the reproducing apparatus, an elevator mechanism for raising and lowering a rotary recording medium supporting member for supporting the rotary recording medium, independently from the turntable, an elevator motor for operating the elevator mechanism, when the elevator motor operates so that the support member is at a raised position due to the operation of the elevator mechanism upon insertion of the case into the reproducing apparatus, and an elevator lever member provided respective of the elevator mechanism, for operating the elevator mechanism by operating independently from the elevator motor. The elevator lever member is positioned within a moving passage of a locking guiding part which is a part of the jacket opening enlarging means. Further, the elevator lever member is locked and guided by the locking guiding part and displaced towards a direction so as to operate the elevator means to lower the supporting member so that the supporting member retreats from a case inserting path upon insertion of the case into the reproducing apparatus, and is released of the locking operation by the locking guiding part and displaced towards an opposite direction so as to operate the elevator means to raise the supporting member upon extraction of the case from the reproducing apparatus.
