FLUID EJECTION DEVICE

摘要

A fluid ejection device includes a fluid ejection unit including a plurality of nozzles and configured to eject fluid from at least any one of the nozzles in a pulse-like manner according to a drive signal, a fluid supplying unit configured to supply the fluid to the fluid ejection unit, an ejecting-instruction input unit configured to receive an ejecting instruction input, a mode-selection input unit configured to receive an input of selection information for selecting any one of a first mode for ejecting the fluid using a first nozzle unit including at least one nozzle and a second mode for ejecting the fluid using a second nozzle unit including at least one nozzle, and a fluid-ejecting control unit configured to output, when receiving the ejecting instruction input, according to the selection information, the drive signal such that the fluid is ejected from the first nozzle unit or second nozzle unit.

1. A fluid ejection device comprising:
a fluid ejection unit including a plurality of nozzles for ejecting fluid and configured to eject the fluid from at least any one of the nozzles in a pulse-like manner according to a drive signal; a fluid supplying unit configured to supply the fluid to the fluid ejection unit; an ejecting-instruction input unit configured to receive an ejecting instruction input for ejecting the fluid from the fluid ejection unit; a mode-selection input unit configured to receive an input of selection information for selecting, when the fluid is ejected from the fluid ejection unit, any one of a first mode for ejecting the fluid using a first nozzle unit including at least one of the plurality of nozzles and a second mode for ejecting the fluid using a second nozzle unit including at least one of the plurality of nozzles; and a fluid-ejecting control unit configured to output, when receiving the ejecting instruction input, according to the selection information, the drive signal to the fluid ejection unit such that the fluid is ejected from the first nozzle unit or the second nozzle unit, wherein a total area of cross sections of ejection ports of the nozzles belonging to the second nozzle unit is larger than a total area of cross sections of ejection ports of the nozzles belonging to the first nozzle unit.
