发明名称 Liquid ejecting head and liquid ejecting apparatus
摘要 A cover member is fixed to a head chip in an area in the vicinity of a nozzle plate but does not constitute a communication path, and thus causes no liquid leakage. The head chip discharges droplets of a discharge liquid that is supplied via the communication path which is formed from nozzles thereof without depending on the cover member. A surface of the nozzle plate is positioned on a side further apart from a printing medium than from a surface of the cover member and is surrounded. As a result, abutting of the printing medium against a side surface of the nozzle plate is avoided.

主权项 1. A liquid ejecting head comprising: a lower case member that includes a wall-shaped enclosure surrounding a space; a head chip that discharges a discharge liquid in a communication path through nozzles and that holds a surface of the head chip where the nozzles are formed in such a manner that the surface is exposed to an outside, wherein the head chip includes a plate-shaped nozzle plate that includes the nozzles and that is arranged in a predetermined manner on a side that faces a printing medium, the head chip, including the plate-shape nozzle plate, being disposed within the space of the lower case member within which the head chip is mounted; and a cover member that includes an opening that is capable of exposing the nozzle plate to the outside, wherein the cover member does not constitute the communication path, and wherein the nozzle plate is positioned in an inside area of the opening and the cover member is set to the head chip in an area in a vicinity of the nozzle plate of the head chip.
