Disc-shaped recording medium reproducing apparatus

A reproducing apparatus for reproducing a disc-shaped recording medium which is accommodated within a case, said case comprising a jacket which has a space for accommodating said disc-shaped recording medium and an opening for allowing said disc-shaped recording medium to go in and out of said jacket, and a lid member inserted through said opening of said jacket for closing said opening of said jacket, said reproducing apparatus comprising:

• an inserting opening part through which said case is inserted into said reproducing apparatus;
• a turntable for rotating said disc-shaped recording medium;
• lid member locking means and disc-shaped recording medium clamping means respectively provided at the innermost part of said reproducing apparatus opposite to said inserting opening with respect to said turntable;
• jacket opening enlarging means provided in the vicinity of said inserting opening, moving over said turntable between the position in the vicinity of said inserting opening and said innermost part of said reproducing apparatus, accompanied by operation of inserting said case into and pulling the same from said reproducing apparatus;
• elevating means for moving a member for supporting said disc-shaped recording medium upwards and downwards independent of said turntable, said elevating means assuming a state of elevating said supporting member upon inserting said case into said reproducing apparatus;
• an elevating lever member, provided in conjunction with said elevating means to assume a position entering into a passage of an engagement guide port which constitutes a part of said jacket opening enlarging means upon inserting said case into said reproducing apparatus, and engaged and pushed by said engagement guide part moving accompanied by the insertion of said case to undergo displacement in one direction, causing said elevating means to operate so as to move said supporting member downwards to retreat from an insertion passage of said case;
• and
• locking means, responsive to an insertion operation of said case, for locking said elevating lever member at the position displaced in the one direction so as not allow return displacement thereof, and, responsive to a pulling-out operation of said case, for making said elevating lever member free from locked state to allow said elevating lever to return to the original position thereof.
