Abstract
A print head that discharges a liquid includes: a nozzle plate in which a nozzle aperture through which the liquid is to be discharged in an ejection direction is formed, the nozzle plate being mounted on a liquid ejection surface; a housing that accommodates at least a portion of the nozzle plate; and a handle positioned opposite the nozzle plate in the ejection direction. The handle has a greater strength than that of the housing. At least a portion of the handle is aligned with the nozzle plate in a normal direction of the nozzle plate.
Claims8
A print head that discharges a liquid, the print head comprising:
- a nozzle plate in which a nozzle aperture which extends through the nozzle plate along a penetrating direction and through which the liquid is to be discharged in an ejection direction is formed, the nozzle plate being mounted on a liquid ejection surface;
- an ejection control substrate on which an ejection control circuit that generates an ejection timing signal of the liquid from the nozzle aperture is mounted;
- a housing that accommodates at least a portion of the nozzle plate and the ejection control substrate, the housing having a housing aperture opening along the penetrating direction of the nozzle aperture;
- a handle positioned opposite the nozzle plate in the penetrating direction;
- and
- a connector which is mounted on the ejection control substrate, is attachable to a cable, and to which a control signal for controlling an operation of the print head is to be input via the cable, the connector being exposed via the housing aperture to an outside of the print head,
- the handle having a greater strength than that of the housing,
- at least a portion of the handle being aligned with the nozzle plate in a normal direction of the nozzle plate, which is along the penetrating direction, and
- the connector being misaligned from the handle in the normal direction.
