Abstract
Provided is a liquid ejecting head which includes head bodies aligned in a direction of liquid ejection surface thereof, a flow-path member in which distribution flow path is provided to supply liquid to the head bodies, and flexible wiring substrates connected to the head bodies. The distribution flow path extends in the first direction. In addition, the flexible wiring substrates adjacent in the first direction overlap when viewed from the first direction. The distribution flow path is disposed in an area on one side with respect to the flexible wiring substrates, in a direction perpendicular to the first direction in the liquid ejection surface.
Claims20
A liquid ejecting head comprising:
- a plurality of head main bodies which have liquid ejection surfaces from which liquid is ejected and are aligned in a first direction of the liquid ejection surface;
- a flow-path member in which flow path is provided to supply liquid to the plurality of head main bodies;
- and
- a plurality of flexible wiring substrates which are connected to the head main bodies, each flexible wiring substrate is a flexible circuit board or a chip on flexible film,
- wherein the flow path includes a plurality of connection portions which are connected to the head main bodies and a distribution flow path which communicates with the plurality of connection portions and extends in the first direction,
- wherein a second direction in which the flexible wiring substrate extends from the head main body side to the flow-path member side intersects the first direction,
- wherein the flexible wiring substrates which are adjacent in the first direction overlap when viewed from the first direction, and
- wherein the distribution flow path is disposed in an area on one side with respect to the flexible wiring substrates, in a direction perpendicular to the first direction in the liquid ejection surface.
