摘要： A reference voltage waveform reciprocating between a first voltage and a second voltage is supplied to a piezoelectric element via a switch. If a switch is set to a connected state (ON), the reference voltage waveform is applied to the piezoelectric element, and if the switch is set to a disconnected state (OFF), the voltage when the switch is set to OFF continues to be applied. Therefore, it becomes possible to apply a variety of drive signals only by switching the switch in accordance with increase and decrease of the reference voltage waveform, and there is no need to store a plurality of types of drive signals. Further, it is possible to start to apply the drive signal immediately when the voltage of the reference voltage waveform reaches the target voltage.
