Abstract
There is provided an ink-jet head including: first and second head chips each formed with two first nozzle arrays extending in a first direction, each of the first nozzle arrays including first nozzles corresponding to a first ink, second nozzles corresponding to a second ink, and third nozzles corresponding to a third ink; third and fourth head chips each formed with two third nozzle arrays extending in the first direction, each of the third nozzle arrays including fourth nozzles corresponding to the fourth ink. The first head chip to the fourth head chip are arranged in parallel in a second direction orthogonal to the first direction.
Claims8
A head chip comprising:
- nozzles A arranged along a first direction;
- nozzles B arranged along the first direction;
- an electrical terminal located at a position between the nozzles A and nozzles B in a second direction orthogonal to the first direction;
- and
- a reservoir formation member formed with a reservoir A communicating with the nozzles A, a reservoir B communicating with the nozzles B, a first communication port communicating with the reservoir A, and a first connection channel connecting the reservoir A and the reservoir B,
- wherein the reservoir formation member defines a through hole through which the electrical terminal is exposed, and
- wherein the first connection channel connects the reservoir A and the reservoir B to run around the electrical terminal at on a first end side of the head chip in the first direction.
