摘要： It is an object of the present invention to ensure a desired precision in positioning an orifice plate with respect to liquid flow paths of a head main body, so as to prevent a failure liquid discharge which will possibly be caused due to a problem involved in a process of forming the orifice holes. In detail, a head main body is formed on the lower wall thereof a plurality of heating elements, has a plurality of liquid flow paths formed by dividing an internal space with a plurality of liquid flow path walls and arranged in parallel relationship with one another. On either side of the plurality of the liquid flow paths there are formed two dummy liquid flow paths. An orifice plate is formed with a plurality of orifice holes arranged in parallel with one another for discharging ink. Further, on either side of the plurality of the orifice holes there are formed two projected portions so shaped that they are capable of engaging with the opening ends of the dummy liquid flow paths. Each of the projected portions is formed with a dummy orifice hole which is not used for discharging ink during recording operation. A desired positioning can be effected by engaging the projected portions of the orifice plate with the dummy liquid flow paths.

摘要： A method for manufacturing a liquid discharge head comprises the steps of providing a head main body having liquid flow paths, and an aperture surface having flow path openings communicated with the flow paths; providing a discharge port plate having extrusions each on the circumference of an inside opening communicated with each of the discharge ports, being on the inner face on the side opposite to the discharge port surface provided with discharge ports for discharging liquid, and a base having a substantially flat surface. For this method, the discharge port plate is arranged in a state of these surfaces formed integrally to be in contact; bonding the aperture surface and the inner face to fit the extrusions into the flow path openings by pressing the head main body and the base in the direction of the head main body and the base approaching each other with the discharge port plate between them; and separating the base from other members. With the method of manufacture thus structure, the liquid discharge head presents an excellent discharge efficiency by the provision of the extrusions that enter the flow paths from the orifice plate. It also becomes possible to manufacture a highly reliable liquid discharge head by a simpler manufacturing apparatus in a shorter period of time at lower costs.

摘要： A liquid jet recording head comprises a first substrate having a plurality of discharge energy generating devices formed thereon, and a second substrate having a discharge opening plate provided with a plurality of discharge openings for discharging ink, and recessed portions becoming ink flow paths conductively connected with said discharge openings, and a common liquid chamber for retaining ink to be supplied to each of said discharge openings, respectively. The ink flow paths and common liquid chamber are formed by joining the first substrate and second substrate with the discharge energy generating devices of the first substrate facing the recessed portions becoming ink flow paths of the second substrate, at the same time, the joint between the first substrate and second substrate being sealed by sealing compound, and fine grains inclusively residing on the joint between the first substrate and second substrate. With the liquid jet recording head thus structured, there is no possibility that sealing compound flows into the ink flow paths and discharge openings even if the joint between the first and second substrates are sealed by sealing compound, and that any defective prints take place. The production yield in the sealing step of manufacture is increased, at the same time, the controlling burden is lightened.
