ABSTRACT:
When a DC motor is restarted, a drive signal for the DC motor serves as a pulse signal. Even when a printer is stopped under a maximum load, the DC motor may be restarted a plurality of times, thus vibrating the DC motor and reducing the degree to which the printer is locked. This makes it possible to easily restart the DC motor.
