STEPPING MOTOR CONTROL DEVICE

PROBLEM TO BE SOLVED: To provide a stepping motor control device which can commonly transmit motor drive signals from a CPU to a plurality of stepping motors, and can drive only the selected stepping motor by using a drive motor selection signal. SOLUTION: The stepping motor control device includes the plurality of stepping motors 1; a switching circuit 2 for each of the stepping motors 1; the CPU 3, having a drive motor selection function and a motor signal generating function; and a connecting part 4 commonly connected to phase windings of the plurality of stepping motors 1. Thus, there can be provided the stepping motor control device which has the effect of making the drive signals common to the plurality of stepping motors 1, optimizing cost, and reducing the device in size.
