Abstract

PURPOSE:To make small the size of device by omitting flywheels, by enabling to switch the run of magnetic tape and the mode selection with one direct drive motor. CONSTITUTION:The capstan shaft is directly coupled with the output shaft of a direct drive motor (hereinafter D motor) 5, and the pinch roller 3C receiving the torque of the D motor 5 via the control of a controller is provided on the chassis 1. Further, the pinch roller 3C is provided with FF shift cam 29A sliding forward and reverse the subchassis 7, and REW shift cam 30A operating the transmission means transmitting the torque of the D motor 5 to the winding reel stand. With the rotation of the pinch roller 3C accompanied with the control of the controller, the subchassis 7 is in forward and reverse slide location, allowing the torque of the D motor 5 to be delivered to the winding reel stand or not.
