PROBLEM TO BE SOLVED: To make control capable efficiently in a short time of rotation of a shaft of a plurality of stepper motors with a step position different of each shaft. SOLUTION: In a CPU 1, a pattern data of an excitation current corresponding to each stop position from in the first to in the n-th is output successively clockwise and counter clockwise. In the case of outputting the pattern data successively corresponding to each stop position of a shaft clockwise, of each stepper motor 7-k , corresponding to each stepping motor changing a stop position of the shaft clockwise, in a period leading to a stop position which must be changed from the present stop position of each stepper motor 7-k storing an order of the pattern data in a RAM3, a respectively corresponding clock signal CKk is output. |
