Patent ID: 7159793

Claim:
A liquid discharging head comprising: a plurality of liquid discharging units including liquid chambers, discharge force applying means, and a nozzle member, the liquid chambers containing liquid to be discharged, the discharge force applying means being disposed proximate the liquid chambers for applying discharge force to the liquid in the liquid chambers, and the nozzle member having nozzles through which the liquid in the liquid chambers is discharged; and a common flow path for supplying the liquid to the liquid chambers of the liquid discharging units, wherein the liquid discharging units are disposed at a predetermined pitch P so that communication portions of the ink chambers with the common flow path face the same direction in relation to the common flow path, wherein the centers of the nozzles of adjacent liquid discharging units among the liquid discharging units are separated at an interval X in a direction perpendicular to a direction of arrangement of the liquid discharging units, where X is a real number greater than 0, and wherein the liquid discharging units are disposed so that the relationship between the pitch P and the interval X is: X=P/2.
