Abstract
A control method for a piezoelectric drive device includes a piezoelectric vibrator having a vibrating portion and a distal end portion coupled to the vibrating portion, in which the distal end portion makes elliptic motion by a stretching vibration and a flexural vibration of the vibrating portion, a driven member driven by the elliptic motion of the distal end portion, and a drive signal generation circuit outputting a stretching vibration drive signal that generates the stretching vibration and a flexural vibration drive signal that generates the flexural vibration in the piezoelectric vibrator, and the method includes, when the driven member is stopped, superimposing and outputting a modulation signal for amplitude modification on the stretching vibration drive signal by the drive signal generation circuit.
