Abstract
A drive control apparatus includes a storage configured to store waveform data representing a drive signal constituted of a sine wave satisfying a frequency f=(m/n)×f(m and n are mutually different positive odd numbers), the drive signal applying vibration (m/2)×Q times (Q is a natural number other than 0) to an actuator, the frepresenting a resonant frequency of the actuator, and a drive controller configured to read the waveform data stored in the storage, and output the drive signal corresponding to the read waveform data to the actuator.
