PROBLEM TO BE SOLVED: To improve the reliability of an apparatus by reducing interruption processes of a microprocessor when a plurality of stepping motors are controlled simultaneously. SOLUTION: Stepping motors are sorted to those requiring the interruption process and those not requiring the interruption process. The former is subjected to a process of switching phases of stepping motors by data stored in a RAM in a control circuit. COPYRIGHT: (C)2003,JPO |
