Abstract
A stepping motor control device is a device for controlling a stepping motor to be driven by an input of a drive signal and includes a control signal generator and a drive signal generator. The control signal generator generates a predetermined control signal. The drive signal generator generates a drive signal for rotation by a predetermined step angle every time the control signal is input. The control signal generator sets a time interval between a first control signal for starting the stepping motor from a stopped state and a second control signal at one-third of a natural vibration frequency of the stepping motor.
