摘要: A liquid discharge head includes a nozzle plate having a nozzle from which a liquid is discharged, a housing holding the nozzle plate, a valve that opens and closes the nozzle, an expandable driver disposed inside the housing, and a restraint. The expandable driver has a first end that supports a rear end of the valve and a second end fixed to the housing. The expendable driver moves the valve in a longitudinal direction to push a leading end of the valve against the nozzle to close the nozzle. The restraint positions the second end with respect to the housing in the longitudinal direction. A difference between ΔL1 and ΔL2 is equal to or less than a predetermined value, where ΔL1 represents a thermal deformation amount of a first length due to temperature change, and ΔL2 represents a thermal deformation amount of a second length due to the temperature change.

摘要: A discharge head includes a nozzle, a valve body, a piezoelectric element, and a first biasing unit. The nozzle is configured to discharge liquid. The valve body is configured to open and close the nozzle. The piezoelectric element is configured to drive the valve body. The first biasing unit is disposed in parallel with the piezoelectric element. The piezoelectric element is configured to drive the valve body in a direction to open the nozzle when a voltage is applied to the piezoelectric element. The first biasing unit is configured to bias the valve body in the direction to open the nozzle.

摘要: A liquid discharger includes a head to discharge liquid droplets, a cap to cover a nozzle face of the head; a cap mover to move the cap to a capping position at which the cap faces the nozzle face of the head or to move the cap to an evacuation position at which the cap does not face the nozzle face of the head. Further, there is a belt arranged to face and clean the cap at the evacuation position, the belt having a width and length enough to cover whole area of a rim of the cap; a conveyer to drive the belt, and a belt cleaner which faces the belt to clean the belt.
