<p>PURPOSE:To improve considerably the economic efficiency and the operability, by using the power of a motor driving a cassette tape to take in and out a driving part automatically to and from a device body horizontally and taking it in and out in the state of the forward rotation of the motor. CONSTITUTION:When a button 4 which controls taking-in and out of the driving part is depressed, a trigger arm 29 is rotated, and a main gear 23 becomes free. Simultaneously, a switch 34 is turned on to rotate a motor 11. By rotation of the main gear 23, a pinion gear 26 is moved backward on a rack A28. Simultaneously, the whole of the driving part of the cassette tape is slid on a guide rail 16 in the direction of an arrow B and is pulled out because the pinion gear 26 meshes with a rack B28 also. At this time, a detaining part 23c of the main gear 23 is stopped by a detaining pin 31 to stop the rotation of the main gear 23, and the driving part of the cassette tape is stopped in a prescribed position because an intermittent part 23f comes to the part of a pinion 21a of a stepped gear 21, and simultaneously, the switch 34 is turned off.</p> |
