<p>PURPOSE:To move down a cassette holder held under its horizontal state by a holding plate into a play state by making the holding plate horizontally turnable against its restoring spring in accordance with the intrusion of a cassette. CONSTITUTION:An operating piece 15 traversing a guide groove 7 is pressed against the cassette P by the intrusion of the cassette, so that the holding plate 14 is horizontally turned anticlockwise against the restoring spring 34, and consequently since a projecting part 16 is deviated from an upper edge of a side panel 1a of a case frame 1, a slantwise moving member 5a of the cassette holder 5 held horizontally by the holding plate 14 under the nonplay state is allowed for its downward slantwise movement. Therefore, an operating segment 17 is turned anticlockwise by a spring 23 to release a stopping piece 18 and a restraining piece 20 from their restraint, so that an ejection lever 4 is retreated by a spring 19 into an ejecting operatable position, while the slantwise moving member 5a is moved downward and slatwise via a restraining pin 22 and a notched groove 5a' under their restraint, and also a holding frame 5b is lowered under its horizontal state to effect the play state.</p> |
