Abstract

PURPOSE:To obtain the necessary torque even in the time of low speed driving by differentiating the driving current of a stepping motor in the time of high feed from that in the time of low feed. CONSTITUTION:A clock is supplied to a CPU 40 from a pulse oscillator 31 which is also functioned for the drive of a stepping motor. A phase control signal necessary for driving the stepping motor 33 is formed by the CPU 40. And, a control signal for a timer circuit 41 is outputted from the CPU 40, a current switching circuit 60 operates by the output S of the timer, and the necessary torque is obtained even in the time of low speed driving by differentiating the driving current in the time of high feed from that in the time of low feed.
