摘要： 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.

摘要： There is provided a liquid discharge apparatus including: a liquid-chamber that communicates with a nozzle and a flow-chapel; a liquid chamber driving unit that changes a volume of the liquid-chamber; and a valve that changes a volume of the flow-channel. At least one of first control of increasing the volume of the liquid-chamber, such that a change amount of the volume of the liquid-chamber is equal to or larger than a volume of the liquid flowing from the flow-channel into the liquid-chamber due to the decrease in volume of the flow-channel by the valve, and second control of decreasing the volume of the liquid-chamber, such that a change amount of the volume of the liquid-chamber is equal to or larger than a volume of the liquid flowing from the liquid-chamber out to the flow-channel due to the increase in volume of the flow-channel by the valve, is executed.

摘要： In a droplet discharge head, in an initial state in which a tip of the actuator has contact with the vibrating plate, and the actuator pushes the vibrating plate toward the first direction, based on a drive signal from the control section, the tip of the actuator displaces the vibrating plate toward the second direction in a state of having contact with the vibrating plate to thereby pull in a meniscus in the nozzle toward the liquid chamber, then, the tip of the actuator is separated from the vibrating plate to further displace the vibrating plate toward the second direction, and then, the tip of the actuator collides with the vibrating plate to thereby displace the vibrating plate toward the first direction to discharge the liquid from the nozzle.

摘要： A fluid discharge apparatus includes a storage chamber, a moving body, a drive mechanism, and a coupling member. The storage chamber includes a discharge port to discharge the fluid. The moving body includes a leading end portion facing the discharge port inside the storage chamber. The drive mechanism is positioned on the opposite side of the moving body to the discharge port, and performs an operation to reciprocate the moving body. The coupling member couples the moving body to the drive mechanism such that the moving body is attachable and detachable. The coupling member includes a biasing section to apply an elastic force in a direction to move the moving body toward the drive mechanism, and, while pressing the moving body against the coupling member, to support the moving body in a state in which the moving body is capable of elastic displacement in a direction toward the discharge port.
