LIQUID DROP EJECTION HEAD, METHOD FOR MANUFACTURING THE SAME, AND LIQUID DROP EJECTOR

摘要

PROBLEM TO BE SOLVED: To improve the positioning accuracy of a liquid drop ejection head to a liquid drop ejector to improve image quality and to reduce the manufacturing cost of the liquid drop ejection head.

SOLUTION: The liquid drop ejection head includes: a nozzle plate that has a plurality of nozzle ejection ports; an individual passage substrate formed with a plurality of individual liquid chambers for supplying liquid drops to the nozzle ejection ports and having electromechanical conversion elements for pressurizing liquid drops in the individual liquid chambers; common passage substrates for supplying liquid drops to the individual passage substrate; a base plate 30 engaged with a predetermined position of an ink jet recorder, and having metallic position reference surfaces 30a, 30b for positioning the direction along the opening surfaces of the nozzle ejection ports to the inkjet recorder; and a resin housing 40 having position reference surfaces 40a for positioning the direction to intersect the opening surfaces of the nozzle ejection ports to the inkjet recorder.
