PURPOSE:To implement the quick control of a motor effectively by giving a control signal reverse to the previous one immediately after the main control signal has disappeared. CONSTITUTION:When a pulse a is inputted, it is inputted to a transistor A through a diode I1, switching it to 'ON' to rotate a motor. When the pulse a disappears, a preset time pulse is outputted through NOT element G2 and one-shot element G2 and is inputted to a transistor B through a diode I3. Thus the transistor B is switched to 'ON' and the reverse current is supplied to the motor for a fixed time, which is the other way around when the pulse a is inputted. Similarly, when a pulse b is supplied, the reverse current to the current by the pulse b is supplied to the motor for a fixed time.
