发明名称 LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS
摘要 A liquid ejecting head includes: a first pressure generation chamber communicating with a first nozzle opening via a first communication path, and a second pressure generation chamber communicating with a second nozzle opening via a second communication path. The first and second pressure generation chambers are aligned in a first direction. The first communication path includes, on one side of a second direction, a first oblique portion with a section area changing from a side of the first pressure generation chamber toward the first nozzle opening. The second communication path includes, on the other side of the second direction, a second oblique portion with a section area changing from a side of the second pressure generation chamber toward the second nozzle opening.

主权项 1. A liquid ejecting head comprising: a pressure chamber substrate that includes a plurality of pressure generation chambers; a nozzle plate that includes a plurality of nozzle openings; and a plurality of communication paths connecting the respective pressure generation chambers and the respective nozzle openings and have oblique portions with section areas changing from inlets on a side of the pressure generation chambers toward outlets on a side of the nozzle openings, wherein the oblique portions are arranged in the communication paths on the side of the pressure generation chambers or the side of the nozzle openings in a third direction, wherein the plurality of pressure generation chambers are aligned in a first direction and include a first pressure generation chamber and a second pressure generation chamber that are adjacent to each other in the first direction, wherein the first pressure generation chamber communicates with a first nozzle opening from among the nozzle openings via a first communication path from among the plurality of communication paths, wherein the second pressure generation chamber communicates with a second nozzle opening from among the nozzle openings via a second communication path from among the plurality of communication paths, wherein the first communication path includes, on one side of a second direction, a first oblique portion with a section area changing from a side of the first pressure generation chamber toward the first nozzle opening, wherein the second communication path includes, on the other side of the second direction, a second oblique portion with a section area changing from a side of the second pressure generation chamber toward the second nozzle opening, wherein the first direction is orthogonal to the second direction on the nozzle plate, and wherein the third direction is a direction orthogonal to both the first direction and the second direction.
