ABSTRACT:
A rotary recording medium reproducing apparatus for reproduces a rotary recording medium accommodated within a case. 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 has a rotary recording medium clamping mechanism provided at an innermost part of the reproducing apparatus, for clamping an outer peripheral groove guard of the rotary recording medium when the case is inserted into the reproducing apparatus and then the jacket is pulled out from the reproducing apparatus. The rotary recording medium clamping mechanism comprises a rotatable lower clamp member, a mechanism for holding the lower clamp member to assume a substantially horizontal position upon clamping, an upper clamp member provided rotatable to oppose the lower clamp member and having projection projected downwards at a tip end thereof, and a mechanism for locking the upper clamp arm, after the outer peripheral groove guard of the rotary recording medium enters between the upper and lower clamp members, in a state where the projection faces the inner side of the outer peripheral groove guard.
