DEVICE AND METHOD FOR EJECTION OF LIQUID

摘要

PROBLEM TO BE SOLVED: To generate an accurate drive signal that is strong in disturbance in a liquid ejection device.

SOLUTION: A liquid ejection device includes: (A) a control part that generates an analog voltage signal based on the digital signal that defines the waveform shape of the signal; (B) a head part which includes a voltage waveform signal generation part that amplifies the voltage and amplifies the current of the analog voltage signal and generates the voltage waveform signal and an element that jets the liquid from a nozzle and that is driven according to the potential difference of the voltage waveform signal and the ground; and (C) a transmission part that transmits the analog voltage signal from the control part to the head part. The transmission part has: a twisted-pair cable in which a transmission line that transmits the analog voltage signal and a ground line are twisted; or a coaxial cable in which the transmission line is enclosed concentrically by the ground line.
