<p>PURPOSE:To improve durability, to smooth lock operation and to make a cassette loading mechanism compact and thin by composing the mechanism, which locks a cassette holding part in a loading completing position, of a lock arm, a kick arm and a slide plate. CONSTITUTION:A cassette holding part 10 is moved to the loading completing position and a pin 223 of an arm 22 is contacted to a projecting piece 441 of a kick arm 44, the arm 44 is turned in a counter-clock-wise direction and a locking part 442 of the arm 44 creeps into the lower side of a claw part 432a in a slide plate 43. Then, the lock of the plate 43 is canceled and the plate 43 is slided by a spring 45. Simultaneously, the arm 41 is turned in a clock-wise direction with being interlocked to the turning of the arm 44 in the counter- clock-wise direction. When the holding part 10 is locked in the loading completing position, the arm 41 is turned in the clock-wise direction and the pin 223 of the arm 22 is locked in a circular arc part 412.</p> |
