Ink-jet recording apparatus |
摘要 |
An ink-jet recording apparatus has an ink-jet head with a plurality of nozzle openings, a plurality of independent ejection chambers respectively communicating with the nozzle openings, diaphragms respectively formed in the ejection chambers partly on at least one side wall of each of the ejection chambers, a plurality of driving electrodes for respectively driving the diaphragms, and a common ink cavity for supplying ink to the plurality of ejection chambers. Upon application of electric pulses to the plurality of driving electrodes, the driving electrodes respectively distort the diaphragms by electrostatic force in a direction to increase the pressures in the respective ejection chambers to eject ink drops from the nozzle openings onto recording paper.
