ABSTRACT:
A vibration type motor device in which a travelling wave is formed by applying a cyclic signal to a piezoelectric member so as to vibrate a vibration member, thereby driving a moving member. When a cyclic signal actually applied to the piezoelectric member has a frequency near the resonance frequency, it is determined whether the moving member can be properly driven.
