<p>PROBLEM TO BE SOLVED: To prevent plastic deformation and early insertion of a holder by stopping a cassette as it is until the cassette is lowered to a play back position or lifted from a drive mechanism. SOLUTION: When a cassette 15 is inserted, a holder supporting wall surface 10f slides along the inclining surface 16b of a spring 16 which thereby presses a holder by means of an upper chip 16a. Under that state, not a lower chip 16c but the upper chip 16a acts on the holder to reduce the force being applied thereto. In this regard, a discharge lever presses the holder reversely to the inserting direction and the holder turns upward on an insertion inclining surface 10e abutting against the upper edge 15c of cassette. Since the holder turns about a rear edge support 10ab, the holder is not deformed. Since a holder stop part 10g comes in front of a bridge 3b as a result of turning operation, further operation of the bridge 3b is blocked and the holder can not turn under that state.</p> |
