Patent ID: 8235506

Claim:
An electrostatic suction type fluid discharge device which discharges by electrostatic suction a fluid, which is electrically charged by voltage application, from a fluid discharge hole of a nozzle of a discharge head onto a substrate opposite to the nozzle, wherein: the electrostatic suction type fluid discharge device comprises line-drawing means for applying a voltage between the nozzle and the substrate while relatively moving the nozzle and the substrate so as to carry out line-drawing, the voltage being equal to or greater than a minimum voltage to induce discharge, that is a voltage required to start discharge of the fluid, the line-drawing means controlling a speed of the relative movement so that adjacent ones of discharge pattern are partly overlaid with each other, in accordance with a period of intermittent discharge which is performed when applying a direct current bias voltage equal to or greater than the minimum voltage to induce discharge and which is performed at a frequency depending on the direct current bias voltage and an electric conductivity of the fluid, and the fluid discharge hole of the nozzle having a diameter ranging from 0.01 μm to 15 μm, and the discharge head discharging the fluid from the nozzle not by a piezo element and/or a thermal element, but by electrostatic suction.
