摘要：Provided is a driving system for a vibrating type actuator capable of simplifyinga driving circuit. A vibrating body of the vibrating type actuator can generate a first mode

and a second mode which are different in a vibration form, in accordance with an alternatecurrent signal to be supplied. An alternate current signal having a frequency close to aresonance frequency in the first mode or the second mode is applied either between anelectrode Va and a common electrode Vc or between an electrode Vb and the commonelectrode Vc of the vibrating body of the vibrating type actuator. One of the electrodesto be supplied with the alternate current signal is selected by a switching elementoperated based on a signal from a driving direction switch.
