Abstract

A piezoelectric driving device includes a piezoelectric vibrating body and a driving circuit. The piezoelectric vibrating body includes a contact which comes into contact with a driven member, and a piezoelectric element which generates vibration in accordance with a driving voltage. The driving circuit sets a driving frequency of the driving voltage to a first frequency and starts the driving at the time of initiation from a stopped state, and sets the driving frequency of the driving voltage to a second frequency lower than the first frequency in a driving state after the initiation.
