<p>PURPOSE:To switch operation modes smoothly with a slight load, by allowing a body of revolution and a tape driving means which are driven by a motor to engage with each other and to interlock themselves only when tape leading-out means reciprocate between specific positions. CONSTITUTION:When a playback button is pressed in a stop mode and a cam 162 rotate by 40 degrees, a partial gear 43 and a sector gear 45 engage with each other to move tape leading-out members 182 and 183. When the cam rotates by 160 degrees, sector gears 29 and 57 disengage from each other and on rotation by 180 degrees, guide pins 23 and 27 are pressed against fixed members 184 and 185. At 200 degrees, a main rod 48 moves to finish pressing of a pinch roll 192 against a capstan 72. At this time, the partial gear 43 and sector gear 45 disengage from each other and the cam 162 rotates without receiving the force of the press contacting. Then, the cam 162 stops at 205 degrees. When a stop button is pressed, a motor reverses to separate the pinch roll 192 from the capstan 72 and the leading-out members 182 and 183 are moved toward a cassette. Further, an idler gear engages with a feeding reel idler gear to wind the tape around a feeding reel without any sag. Then, the cam stops at a 0-degree angle of rotation.</p> |
