<p>PROBLEM TO BE SOLVED: To suppress an increase in burden on a CPU and power consumption, while rapidly detecting step-out of a stepping motor.SOLUTION: A stepping motor control device includes comparison means (115) for comparing a detection signal from rotation detection means (104 and 105) for detecting rotation of a stepping motor (103) for driving a driven member (100) with a drive signal for driving the stepping motor, in a predetermined period, and changing means (118) for changing the predetermined period depending on a drive state of the stepping motor.</p> |
