ABSTRACT:
A pulse motor driving apparatus is comprised of a timer circuit generating a slue-up pulse and a normal operation pulse, latch circuits latching a phase designating signal in synchronization with the slue-up pulse and normal operation pulse of the timer circuit, and driving circuits driving pulse motors in response to the latched, phase designating signal of the latch circuits. The timer circuit is comprised of first and second counters for generating the slue-up pulse and normal operation pulse. In the slue-up operation mode, two of the pulse motors are driven in synchronization with the output pulses of the first and second counters. Upon completion of the slue-up operation, the two pulse motors are driven in a normal operation mode, in synchronization with the output pulse of the first counter.
