LIQUID JET HEAD AND RECORDER EMPLOYING IT

摘要

PROBLEM TO BE SOLVED: To provide an easy-to-manufacture liquid jet head which can generate a high ejection force without deteriorating ejection efficiency by introducing the bubble generating pressure in a bubble generating region in the direction of ejection opening. SOLUTION: A substrate 110 arranged with heating elements 2, a thin film supporting member 131 having lower surface bonded with a movable separation film 5, and a grooved member 132 are laminated sequentially and tightly onto a support 136 and a orifice plate 9 is bonded tightly to the front face of the grooved member 132. Ejection liquid in a first liquid channel (ejection liquid channel) is separated completely from bubbling liquid in a second liquid channel (bubbling liquid channel) by the movable separation film 5.
