Abstract:
A liquid ejection head includes: a first head unit; a second head unit disposed adjacent to the first head unit in a first direction and located on a first side of the first head unit in a second direction; and a heat uniforming unit shared by the first head unit and the second head unit. Each of the first head unit and the second head unit includes: a unit body including an actuator; and a first driver integrated circuit disposed on the first side of the unit body in the second direction. The heat uniforming unit includes a first heat uniforming member disposed on the first side of the first head unit and the second head unit in the second direction. The first heat uniforming member includes a first protrusion located next to the second head unit in the first direction and protruding toward the first head unit.

Claim (Index 1):
A liquid ejection head, comprising:\n a first head unit; a second head unit disposed adjacent to the first head unit in a first direction; and a heat uniforming unit shared by the first head unit and the second head unit, the first head unit and the second head unit each comprising:\n a unit body comprising an actuator configured to cause ejection of liquid from a plurality of nozzles; and \n a first driver integrated circuit disposed on a first side of the unit body in a second direction orthogonal to the first direction, the first driver integrated circuit being configured to drive the actuator, the first side and a second side being opposite sides of the first head unit in the second direction, \n the heat uniforming unit comprising a first heat uniforming member disposed on the first side of the first head unit and the second head unit in the second direction, wherein the first heat uniforming member comprises a first-side outer surface and a second-side outer surface, and the first-side outer surface is located on the first side of the second-side outer surface in the second direction, wherein a heat dissipating fin and a rib are formed on the first-side outer surface of the first heat uniforming member, wherein the heat dissipating fin protrudes toward the first side in the second direction and extends in a third direction orthogonal to each of the first direction and the second direction, wherein the rib protrudes toward the first side in the second direction and extends in the first direction, and wherein the rib and the first driver integrated circuit are located at an identical position in the third direction.
