Abstract:
1. A liquid ejecting print head, comprising: a plurality of print head units configured to create an image, and mounted on one surface of a substrate of the liquid ejecting print head, arranged across a longitudinal direction of the liquid ejecting print head, and aligned in a zigzag manner in a direction perpendicular to the longitudinal direction of the liquid ejecting print head; a plurality of nozzle arrays mounted on each of the plurality of print head units, each nozzle array including a plurality of nozzle orifices configured to eject a droplet of ink; an energy generating element mounted on each of the plurality of print head units and provided for each of the plurality of nozzle orifices, the energy generating element configured to generate energy for ejecting the droplet of ink; and a wiring member including for each print head unit of the plurality of print head units, a plurality of wirings corresponding to the print head unit and transmitting respective signals to the energy generating element corresponding to the print head unit, each of the pluralities of wirings for the plurality of print head units being formed to run in an identical wiring direction that is a lateral direction of the plurality of print head units from each print head unit to a given side of the substrate, wherein the plurality of print head units include plural distal print head units located distal in the wiring direction, and include plural proximal print head units located proximal in the wiring direction, and wherein for two adjacent ones of the plural proximal print head units, one of the plural distal print head units is located between the wirings for one of the adjacent proximal print head units and the wirings for the other of the adjacent proximal print head units, and for at least one of the proximal print head units, the wirings for the proximal print head unit passes between two adjacent ones of the plural distal print head units.
