<p>PURPOSE:To reduce the size of a device by achieving constant-speed drive, and rewind and fast-forward drive by one motor, by restricting the motion range of an idler plate according to a loading and an unloading state. CONSTITUTION:A tape is drawn out of a cassette 15 by tape drawing-out members 7 and 8 during playback operation and after the drawing-out operation, a motor 35 is turned as shown by an arrow (a) to turn a capstan 11 as shown by an arrow (b) through a pulley 25, a belt 27 and a flywheel 21. The idler plate 24, on the other hand, is rotated around a fulcrum 26 of rotation as shown by (c), but a control member 16 is rotated by a spring 17 as shown by an arrow (d), stopping power transmission from an idler gear 23 to a T reel turntable 3. During fast-forward and rewind operation, the tape drawing-out members 7 and 8 are contained in the cassette 15, so the idler plate 24 is released from being stopped by the control member 16 to rotate as shown by the arrow (c), performing fast-forward operation.</p> |
