Abstract

PURPOSE:To obtain a small-size, light-weight, and cheap circuit, by detecting the change of a current, which is flowed to a motor which rotates a capstan, to supply power to a motor, which rotates a reel, and drive this motor. CONSTITUTION:A motor for reel drive discs 12 and 13 and a motor 41 for driving a capstan are provided separately. When an H-level signal is supplied to an input terminal 63, an enough current to drive a solenoid plunger 48 is flowed to a point E after a prescribed time to drive the plunger 48; and at this time, since the motor 41 is operated previously, the peak current is flowed to the motor 41 when a pinch roller 28 is pressed to the capstan, and the potential at a point D becomes L-level temporarily by a capacitor C1, and the potential at a point C is restored to the H- level again, and the potential at a point F becomes H-level also. This output is supplied to an LSI for control and etc. through an output terminal 64 to rotate and drive the motor for tape running. Thus, timings of both motors coincide with each other.
