<p>PURPOSE:To absorb the overstroke at the positions of loading and unloading the cassette by connecting the first rotary lever and the second rotary lever that move a cassette holder to the said two positions, with a coil spring. CONSTITUTION:When the cassette 7 is inserted in the cassette holder 13, a guide pin 16a pushes the second lever part 22 and lets only the second rotary lever turn, then a protruding part 23d lets a limit switch 29 close, and a driving motor 8 is started up. Only the first rotary lever 18 turns through s stepped gear 11 and overtakes to the second rotary lever 21. The first gear part 20 and the gear 10 are disengaged, while the second gear part 23 is engaged with the gear 10, and the second rotary lever 21 is turned. Then first rotary lever 18 is turned via the coil spring 24, and the pin 16a is pushed by a first lever part 19. Consequently, the cassette holder 13 reaches the cassette-loading position and the motor 8 stops. In such way, the overstroke is absorbed by means of the coil spring 24.</p> |
