ABSTRACT:
A memory for storing an information which relates to a plurality of different line-segmented-waveforms which correspond to address, a control IC which reads out the information which relates to the inclination of the line-segmented-waveforms from a corresponding memory according to a predetermined readout timing when the address is designated and forms the line-segmented-waveform according to the information which relates to the inclination and generates a driving waveform by combining the line-segmented waveforms, and a driving section which drives the piezoelectric transducer according to the driving waveform so as to eject a liquid drop from an ejecting section are provided. The line-segmented-waveform is formed by waveforms of which a variation amount of voltage becomes smaller nearer an end section of the driving waveform.
