Abstract
A driving device includes a storage unit configured to store waveform data of driving signals for stopping excitation of an actuator at a sinusoidal wave of a resonance frequency of the actuator, at portions other than a center point of an amplitude of the sinusoidal wave; and a processor programmed to execute a process including reading the waveform data stored in the storage unit and outputting, to the actuator, the driving signals corresponding to the waveform data that has been read.
