ABSTRACT:
A sector is provided on a rotary shaft of a stepping motor. Two end edges of this sector define two reference positions. When a sensor detects one of the end edges, a reset signal generator generates a reset signal to reset a counter which counts driving pulses for the stepping motor or fractions thereof. The reset signal generator also generates a distinguishing signal representing which end edge of the sector is detected. The rotary position of the stepping motor is determined based on the content of the counter and the distinguishing signal.
