Liquid ejecting head and liquid ejecting apparatus

Abstract

A liquid ejecting head includes a plurality of nozzle groups each including a plurality of nozzle openings; and a plurality of pressure generating chambers that cause liquid to be ejected from the nozzle openings. A plurality of recessed portions are formed at a nozzle forming member, the recessed portions each having a thickness smaller than a thickness of the nozzle forming member, the nozzle openings being formed at the recessed portions. A set of at least one of the plurality of nozzle openings included in each single nozzle group defines a nozzle set, the nozzle set being arranged to correspond to each of the pressure generating chambers. The nozzle groups each have a plurality of nozzle sets in an array, the nozzle sets of one of the nozzle groups being relatively shifted from the nozzle sets of another one of the nozzle groups in a nozzle-set-array direction.

Description

Liquid ejection head and liquid ejection device technical field The present invention relates to a liquid ejection head such as an inkjet recording head and a liquid ejection device, and more particularly to a liquid ejection device having a plurality of nozzle groups with nozzle openings arranged in a row and a pressure generating chamber communicating with the nozzle openings, wherein the pressure generating chamber is changed to a pressure generating chamber. A liquid ejection head that ejects liquid from a nozzle opening corresponding to the pressure generating chamber, and a liquid ejection device including the ejection head. Background technique A liquid ejecting device is a device that includes a liquid ejecting head capable of ejecting a liquid, and ejects various liquids from the liquid ejecting head. As a representative device of this liquid ejecting device, for example, there is an ink jet type recording head (hereinafter simply referred to as a recording head) ...

AI Technical Summary

Problems solved by technology

In addition, if the ink in the ink cartridge is consumed quickly, the ink cartridge needs to be replaced frequently, thereby increasing the burden on the user in terms of running costs, and there are also problems from the viewpoint of environmental protection.
