Abstract

A driving circuit section generates a voltage waveform for forming a transition period wherein a voltage is not applied between first and second voltage level periods different from each other, and a voltage applied to a piezoelectric element by the voltage waveform is controlled. Since power is not consumed by the piezoelectric element during the transition period, power consumption can be reduced.
