ABSTRACT:
In a stepping motor drive control mechanism, a step drive command is applied sequentially at irregular intervals to drive a stepping motor. When the step drive command is to the stepping motor the stepping motor is driven by one step angle. According to the response characteristic of the stepping motor, an inhibited period when the reception of the next step drive command is inhibited and a reception period when the reception is enabled are set up. If the next step drive command is applied during the inhibited period, the system waits until the reception period. Then, the stepping motor is driven by one step angle.
