<p>PURPOSE:To simplify the constitution, by carrying out an auto-reverse with the inversion of a cassette holder. CONSTITUTION:In a reproduction mode, a support device 5 slides on the main body in the horizontal direction and a switch 19 opens to stop the operation of a motor 16. When the tape end is detected, the motor 16 turns counterclockwise to close the switch 19. Then the device 5 is ejected with a half turn of a gear 17. The motor 16 stops with a contact between a protruded part 5a and a switch 20, and at the same time an electromagnet plunger 15 has an electric conduction. Thus a lever 14 comes out of a hollow part 7a to close a switch 21 and thus to turn a motor 13. As a result, a rotary wheel 7 turns by a half to give a half turn to a holder 2. On the other hand, the switch 21 opens with a half turn of the wheel 7. Thus the motor 16 turns to reset the device 5. In such way, the switch 19 opens when the reproduction position is held steady, and a reproduction mode is obtained by a switch interlocking the switch 19.</p> |
