Patent ID: 6964464

Claim:
A device which is provided with a piezoelectric transducer for driving a liquid drop ejecting head for ejecting a functional liquid by using the piezoelectric transducer comprising: a memory with corresponding address spaces; a controlling section for memorizing an information which relates to an inclination value of a plurality of different line-segmented-waveforms in the memory, reading out the information which relates to the inclination value of line-segmented-waveform from the corresponding memory according to a predetermined readout timing, forming the line-segmented-waveform according to the information which relates to the inclination value, and generating a driving waveform by combining the line-segmented-waveforms; and a driving section for driving the piezoelectric transducer by the driving waveform and ejecting a liquid drop from an ejecting section on the liquid drop ejecting head, wherein the information which relates to the inclination value contains information for a variation amount of voltage of the line-segmented-waveform per a unit interval, a plurality of different information for the variation amount of voltage correspond to the line-segmented-waveform, and a plurality of the different information for the variation amount of voltage are stored in the memory.
