MANUFACTURE OF INK JET HEAD, INK JET HEAD, AND INK JET PRINTER

摘要

PROBLEM TO BE SOLVED: To readily manufacture a full-line type ink jet head having a predetermined resolution with a high yield. SOLUTION: Unit heads 10a, 10b in this ink jet head 1 are connected with each other such that a straight line passing through an ink ejection nozzle 11a at one end of the unit head 10a and an ink ejection nozzle 11b at the other end of the unit head 10b which is to be adjacent to the unit head 10a and a straight line passing through ink ejection nozzles 11 on the unit head 10a or 10b are perpendicular to each other. The ink jet head 1 is disposed such that an angleθbetween the straight line passing through the ink ejection nozzles 11 on each of the connected unit head and a line perpendicular to a conveying direction of a recording paper 12 is satisfied with cosθ=D/P.
