摘要： A fluid jet device including a fluid chamber with variable capacity and a capacity varying section adapted to vary the capacity of the fluid chamber in response to supply of a drive signal. A drive waveform section making the capacity varying section operate so as to compress the capacity of the fluid chamber and a restoring drive waveform section making the capacity varying section operate to restore the capacity of the fluid chamber before compressing the capacity in a signal waveform. The drive signal supply section controls supply content of the drive signal to provide a restoring period adapted to restore a steady state of the fluid flowing toward an inside of the fluid chamber in a period from when the compressing drive waveform section in the drive signal is supplied to when a subsequent compressing drive waveform section is supplied.
