<p>PURPOSE:To reduce necessary operating force to an eject lever and to eject a cassette without waiting for the return of lever by providing an operating member which operates associatively with the pressing operation of the eject lever and is released from the association when the inversion of an inverting spring is completed. CONSTITUTION:When the eject lever 23 is pressed in, the operating member 34 associated with it presses a link 5 through an operating rod 9 and the link 5 moves inward while compressing the inverting spring 6. As a guide roller 30 is elevated on a tapered cam 32 according to the pressing operation, a link 29 turns and an engaging pin 39 comes out of the engaging hole of the operating member 34. Then, the operating member 34 is pressed back to the front side by the force of a resetting spring 36, so the link 5 also turns by the operating rod 9 and a pack stopper 4 is pressed back by the repulsive force of the inverting spring 6 at the same time, ejecting the cassette by both the inverting spring 6 and resetting spring 36. Therefore, the force of the spring 36 may be small. Further, the cassette is ejected immediately by the resetting of the operating member after the pressing operation is completed.</p> |
