    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 producing a liquid discharge head provided with a head main body including plural energy generating elements for generating energy for discharging liquid as a flying liquid droplet, and plural liquid paths in which the energy generating elements are respectively provided, and an orifice plate adjoined to the head main body and provided with plural discharge ports respectively communicating with the liquid paths and plural independent projections formed around the discharge ports and respectively corresponding to the discharge ports so as to enter into the liquid paths and to engage therewith. The method includes steps of forming the plural projections and the discharge ports while a continuous resinous film is transported; separating the film in a continuous manner in a predetermined size including the portion on which the discharge ports are formed, thereby preparing the orifice plate; and adjoining the orifice plate to the head main body.

    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.
