Abstract
The liquid discharge device includes a plurality of volume changing portions and at least one blocking portion. The plurality of volume changing portions are in combination with a plurality of pressure chambers which communicate with nozzles for discharging a liquid and which have inlets through which the liquid flows into the plurality of pressure chambers. The at least one blocking portion blocks communication at the inlets. The plurality of volume changing portions are arranged in a plurality of rows spaced from one another. In a direction along the plurality of rows, the plurality of rows of volume changing portions are staggered from one another. The liquid is discharged from the nozzles by using the plurality of volume changing portions in a state in which the inlets are blocked by the at least one blocking portion.
Claims6
A liquid discharge device comprising:
- a plurality of volume changing portions that are in combination with a plurality of pressure chambers which communicate with nozzles for discharging a liquid and which have inlets through which the liquid flows into the plurality of pressure chambers and
- that change volumes of the plurality of pressure chambers so as to apply pressure to insides of the plurality of pressure chambers, thereby discharging the liquid from the nozzles;
- and
- at least one blocking portion that blocks communication at the inlets, the at least one blocking portion being configured to slide transversely to a direction in which the plurality of volume changing portions change volumes of the plurality of pressure chambers,
- wherein the plurality of volume changing portions are arranged in a plurality of rows spaced from one another,
- wherein, in a direction along the plurality of rows, the plurality of rows of volume changing portions are staggered from one another, and
- wherein the liquid is discharged from the nozzles by using the plurality of volume changing portions in a state in which the inlets are blocked by the at least one blocking portion.
