Liquid ejecting head, liquid ejecting head unit and liquid ejecting apparatus

摘要

A liquid ejecting head includes a pressure generation chamber which fluidly communicates with a nozzle opening through which liquid is discharged, a pressure generation unit which causes pressure change on liquid in the pressure generation chamber, a manifold which serves as a liquid chamber common to a plurality of the pressure generation chambers, a flexible film which is configured to cover the manifold so as to absorb a pressure change generated in the manifold, and a heat generation unit which is formed on the flexible film at a region opposed to the manifold and is made of a pattered metal.

1. A liquid ejecting head comprising:
a pressure generation chamber which fluidly communicates with a nozzle opening through which liquid is discharged; a pressure generation unit which causes pressure change on liquid in the pressure generation chamber; a manifold which serves as a liquid chamber common to a plurality of the pressure generation chambers; a flexible film which is configured to cover at least a portion of the manifold so as to absorb a pressure change generated in the manifold; a vibration plate formed in part by the flexible film and a supporting plate; and a heat generation unit which is formed on the flexible film at a region opposed to the manifold, is a part of the vibration plate formed discontinuously relative to the supporting plate, and is made of a patterned metal.
