摘要
A control device for a stepper motor drives in a 1-2-phase excitation method in response to an input of a drive signal. The control device includes a control signal generating unit and a drive signal generating unit. The control signal generating unit generates a pulsed control signal. The drive signal generating unit generates the drive signal for rotating by a predetermined step angle every time the control signal is input. The predetermined step angle is a half of a step angle of a 2-phase excitation method. The control signal generating unit configures a higher pulse rate of a first to an n-th (n is an integer equal to or more than 2 and equal to or less than 3) control signals in an activation period of the stepper motor than a pulse rate of the control signals following the n-th control signal.
