摘要： A method for coupling a liquid jet head unit is to couple a liquid jet head unit for recording by discharging liquid to a recording medium with a head installation member capable of installing the head unit through an elastic member. This method comprises the steps of preparing a liquid jet head unit structured integrally with two orifice arrays substantially paralleled and a first supply opening group for supplying liquid to the orifice arrays, and a head installation member provided with a second supply opening group corresponding to the first supply opening group for supplying liquid to the liquid jet head unit, and also, an elastic member having holes corresponding to each of the supply opening groups, providing first and second coupling units for one end side and the other end side of the two orifice arrays for coupling the liquid jet head unit and the head unit installation member, respectively and coupling only one face of the liquid jet head unit and the head unit installation member using the first and second coupling units. With the adoption of this method, it is possible to implement stabilized recording on a recording medium by a stabilized ink supply, at the same time, preventing any erroneous installation in the coupling mode.

摘要： An ink jet recording head comprises a grooved ceiling plate provided with a plurality of discharge openings for discharging ink, and a plurality of ink flow path grooves to form ink flow paths conductively connected with the discharge openings, a plurality of elemental substrates provided with a plurality of electrothermal transducing devices to generate thermal energy used for discharging ink, and a metallic pressure member for pressing the plurality of elemental substrates to be in contact with the grooved ceiling plate. The grooved ceiling plate and the elemental substrates are coupled to enable the ink flow path grooves and the electrothermal transducing devices to correspond to each other for the formation of ink flow paths. Here, the pressure member presses the reverse side of the surface of the elemental substrates having the electrothermal transducing devices provided therefor in order to couple the elemental substrates with the grooved ceiling plate. With the structure thus arranged, heat generated by the elemental substrates is efficiently transferred to the pressure member for radiation even for an ink jet recording head having no base plate or having a smaller base plate than the conventional one, while coupling the substrates and ceiling plate closely and reliably for the attainment of high quality recording.
