Patent ID: 7365474

Claim:
A driving system for a vibrating type actuator comprising a driving circuit of the vibrating type actuator for driving a member to be driven by vibrating a vibrating body, comprising: a vibrating body comprising an electrical/mechanical energy transformation element having at least two electrodes and an elastic body to which the electrical/mechanical energy transformation element is fixed, the vibrating body being vibrated in a first vibration mode when alternate current signals with an identical frequency in phase are applied to the two electrodes and being vibrated in a second vibration mode when alternate current signals with an identical frequency in reversed phase are applied to the two electrodes; an alternate current signal generating circuit for generating an alternate current signal as a drive signal to be applied to one of the two electrodes; and an electrode selecting circuit for selecting one of the two electrodes as an electrode to be supplied with the alternate current signal generated by the alternate signal generator.
