ABSTRACT:
Each of liquid ejection units has a casing body having a first pair of faces extending in a first direction, and a second pair of faces connecting the first pair of faces and extending obliquely relative to the first direction, and a plurality of nozzles arranged in the first direction to form a first nozzle array and a second nozzle array. The liquid ejection units are arranged such that one of the second pair of faces in one of the liquid ejection units and one of the second pair of faces in another one of the liquid ejection units are confronted with each other, so that the liquid ejection units are overlapped in both of the first direction and a second direction which is perpendicular to the first direction. Accordingly, the first nozzle array in one of the liquid ejection units and the first nozzle array in another one of the liquid ejection units constitute a first nozzle group, which is continuous as viewed from the second direction, for ejecting a first kind of liquid.
