Patent ID: 8591017

Claim:
A liquid ejecting head comprising: a structure defining a liquid-flow space through which a liquid flows from a liquid supply source toward a plurality of liquid-drop ejecting nozzles; a generally planar partition portion formed so as to extend along a vertical direction and a first direction each intersecting a second direction and configured to partially define the liquid-flow space; the partition portion partially defining a first chamber and a second chamber such that the first and second chamber are arranged in the second direction on respective opposite sides of the partition portion, the first and second chambers having a larger dimension in the vertical direction than that in the second direction, in cross section taken in a plane parallel to the vertical direction and the second direction of arrangement of the first and second chambers; and a planar filter fixed to the partition portion so as to extend along the vertical direction and the first direction, along a surface of the partition portion, and configured to capture foreign matters contained in the liquid in the first chamber, wherein the structure defines a filter chamber with the filter positioned between the first chamber and the filter chamber in the second direction, wherein the filter chamber does not directly communicate with the second chamber, wherein the structure defines a first opening through which the liquid flows into the first chamber during a circulation purging operation, and further defines a second opening through which the liquid flows out of the first chamber during the circulation purging operation, the first opening being located at one side of the filter in the first direction and the second opening being located at the other side of the filter in the first direction, wherein the liquid flows along the filter in the first chamber during the circulation purging operation and, wherein, during the printing operation of the liquid ejecting head to eject droplets of the liquid from the liquid-drop ejecting nozzles, the liquid flows into the first chamber through the second opening and flows to the filter chamber through the filter.
