<p>PURPOSE:To reduce the consumption of an electric power at the driving starting time of a capstan by transmitting the torque fed from the motor for driving a magnetic tape drawing mechanism to a capstan in case of transferring to recording and reproducing mode from a stop state. CONSTITUTION:At the loading time of a magnetic cassette, magnetic tape drawing bodies 8, 9 start to move to a 2nd position, i.e., a dotted line position by the rotation in an arrow mark (a) direction of the motor 19 for loading, the rotational force of the motor 19 is transmitted to a wheel 38a via a belt 49, drum 50, idler 51 and roll 52 and a capstan 38 is actuated. After the magnetic tape drawing bodies 8, 9 being set to the 2nd position, the capstan 38 is subjected to rated rotation and on the other hand a small gear 53, planetary gear 56 and sector gear 57a allow an arm member 57 to be shifted by the turning force of the motor 19, so the transmission of the turning force to a wheel 38a via a roll 52 is released and the load for the capstan 38 is eliminated. The power consumption at the capstan actuation time can thus be reduced.</p> |
