发明名称 Vibration type driving apparatus
摘要 A driving control apparatus of a vibration motor controls the speed of the vibration motor by simultaneously changing the frequency and the amplitude of signals applied thereto, and upon the speed control, a contribution to a rate of change of speed by a change in the driving frequency and a contribution to the rate of change of speed by a change in the amplitude are varied based on a difference between a target speed.
