<p>PURPOSE:To switch slippage torque corresponding to a mode and to reduce the loss of rotational energy, by engaging a rotation transmitting component which constitutes a second slippage mechanism with a first slippage mechanism by linking the pressurizing operation of a pinch roller on a capstan. CONSTITUTION:In a mode of fast feed or rewinding, the first slippage mechanisms 18-24 engage with the rotation transmitting component 33 having the second slippage mechanism, and a torque driving force transmitted from a driving source to an allied gear 17 and a gear 19 is transmitted to a gear 18 via felts 23 and 33C. Meanwhile, in a state where a pinch roller 6 for recording, reproduction, and fast feed reproduction, etc., is abutted with a capstan shaft 43, the torque driving force transmitted to the gear 19 is transmitted to the gear 18 with prescribed slippage torque via the felt 23. In such a way, it is possible to control the slippage torque at need, and to reduce the loss of the rotational energy of the driving source.</p> |
