Abstract

PURPOSE:To stabilize the operation of a magnetic recording/reproducing device, by driving a capstan and a reel driving disk and driving the reel driving disk by gears with a slip torque in a record/reproduction mode and with a synchronous torque in a fast forward/rewind mode respectively. CONSTITUTION:The slip torque of a motor is extracted by a pinion 12 and with forward revolutions of the motor in a record/reproduction mode. Then a reel driving disk 30b of the take-up side is revolved toward an arrow E. On the other hand, the synchronous torque is extracted by a pulley 8, and a capstan 15 is revolved toward an arrow F. Then a pinch roll 34 moves away from the capstan 15 in a fast forward/rewind mode, and a cam follower 45 hits an expanded part 46a of a cam 46. Therefore a gear 41 engages with pinions 12 and 40 at a time. Thus the synchronous torque is extracted from the pinion 12, and an idler 36 engages with a gear 37b. As a result, a satisfactory take-up torque is obtained. If such a way, a stable operation is secured for a magnetic recording/reproducing device.
