PROBLEM TO BE SOLVED: To provide a compact liquid droplet ejection apparatus in which ejection variance between ejection ports is suppressed without using a dedicated circuit structure. SOLUTION: In the liquid droplet ejection apparatus that selects one nozzle among a plurality of nozzles for ejecting liquid droplets and ejects the liquid droplets, a voltage parameter acquisition part 603 reads out the parameter of an applied voltage of the selected nozzle by searching a voltage table 627, transmitting the read-out parameter to an ejection control part, and the ejection control part forms a voltage signal based on the parameter to apply it to the electrode of the selected nozzle, making the nozzle eject droplets. A voltage control circuit for individual nozzles is not necessary in the liquid droplet ejection apparatus, enabling the equipment to be made compact. COPYRIGHT: (C)2011,JPO&INPIT |
