<p>PURPOSE:To simplify the constitution and also to facilitate the easy distribution of parts with a drive mechanism of the reel turntable, by rotating the 1st rotary shaft with the revolving power of a driving motor with the 2nd rotary shaft revolved in a body with the 1st rotary shaft and securing the selective switch and engagement with a gear having a different revolution transmitting speed by the displaced position of the 2nd rotary shaft. CONSTITUTION:A rotary shaft 42 slides toward an arrow X1 and has a displacement there shown by a solid line, and a worm 43 engages a gear 50 with revolutions. Thus the counterclockwise revolving power of a driving motor 33 is transmitted to a drive gear 54 which engages a gear 51. The gear 51 is decelerated down to a speed ratio against the gear 54 and therefore a reel drive disk gear 57 is driven clockwise at the tape-up side. A record/reproduction mode is set and a tape is taken up a reel 58 at the take-up side. Then a fast forward mode is set to actuate a plunger 48 of a switch mechanism 49. Thus an arm 48a is slided toward an arrow mark Y1. While a lever 46 is turned counterclockwise. Therefore, the worm 43 engages a gear 53 for rapid traverse/ rewind mode. As a result, the revolving power of the motor 33 is transmitted to the gear 54 unified with the gear 53.</p> |
