<p>PURPOSE:To decrease the number of parts by detecting the arrival of a cassette holder at the positions of loading completion and unloading by means of one detecting means and controlling a driving motor. CONSTITUTION:When a cassette 7 is inserted in the cassette holder 13, a guide pin 16a pushes the second lever part 22 and only the second rotary lever turns, and a protruding part 23d turns along an arc-shaped protruded piece 20b, so that a limit switch 29 moves upward in order to provide the closed state. At this point, the pushing of the cassette is at its completing point, and thereafter, the driving motor is started up, and the first and second turning levers 18 and 21 turn until the cassette reaches the position of cassette. When ejecting, the motor 8 turns in the reverse direction, and the levers 18 and 21 turn to let the guide pin 16a be pushed by the second lever part 22. When the cassette holder 13 reaches the cassette unloading position, the limit switch 29 falls between the arc-shaped protruded piece 20b and an opening part 23b to provide the open state, and the motor 8 is stopped.</p> |
