Abstract
The liquid ejection head comprises: a nozzle plate including a nozzle surface in which a plurality of nozzles from which liquid is ejected are formed, the nozzles being arranged two-dimensionally; a pressure chamber forming plate in which a plurality of pressure chambers connected to the nozzles are formed; an elastic member interposed between the nozzle plate and the pressure chamber forming plate; and a deflection device causing the nozzle plate to move in a direction parallel to the nozzle surface so that a direction of ejection of the liquid ejected from each of the nozzles is deflected.
Claims6
A liquid ejection head, comprising:
- a nozzle plate including a plurality of nozzles which are arranged two-dimensionally and from which liquid is ejected;
- a pressure chamber forming plate in which a plurality of pressure chambers connected to the nozzles are formed;
- an elastic member interposed between the nozzle plate and the pressure chamber forming plate;
- and
- a deflection device causing the nozzle plate to move parallel to the nozzle surface creating a deflected direction of ejection, wherein piezoelectric actuators change a volume in the plurality of pressure chambers, in proportion to a voltage applied to the piezoelectric actuators, to eject liquid from the plurality of nozzles.
A liquid ejection head, comprising:
- a nozzle plate including a plurality of nozzles which are arranged two-dimensionally and from which liquid is ejected;
- and
- a deflection device in a form of a plate, is affixed to one surface of the nozzle plate, and causes the nozzle plate to bend creating a deflected direction of ejection, wherein piezoelectric actuators change a volume in the plurality of pressure chambers, in proportion to a voltage applied to the piezoelectric actuators, to eject liquid from the plurality of nozzles.
