Abstract: A liquid ejection head includes a recording element substrate, a flow path member having a common supply flow path and a common collection flow path through which a liquid having a temperature higher than a temperature of the common supply flow path flows, and a support member supporting the flow path member. The common supply flow path and the common collection flow path are formed to extend along a longitudinal direction of the flow path member and be arranged side by side with each other in a lateral direction of the flow path member. The positions of the flow path member in the longitudinal direction and in the lateral direction are defined at a center portion in the longitudinal direction, and at a side surface located on the common supply flow path side in the lateral direction, among side surfaces extending in the longitudinal direction, respectively.

Abstract: A resin molding method includes a first molding step, a sliding step, a second molding step and a mold opening step. In the first molding step, first molded part supported in a fixed mold and a second molded part supported in a die slide mold are molded in different positions in a second direction. In the sliding step, the movable mold is removed in a first direction and the first molded part and the second molded part are aligned by the die slide mold is moved in the second direction. In the second molding step, the movable mold is clamped again with the fixed mold and resin is injected into engaged portions. Each of the first molded part and the second molded part includes at least one wall extending in the first direction, and in the second molding step, the first molded part and the second molded part are engaged with each other at sides of the walls extending in the first direction.

Abstract: A method of manufacturing a liquid ejecting method includes: a first step of injection molding passage members collectively constituting a passage for a liquid in the liquid ejecting head; a second step of moving the passage members to bring the passage members into contact with each other; and a third step of injecting a sealing material into a space between the passage members held in contact with each other, and filling the space with the sealing material. The sealing material is injected and filled, from a gate on a longitudinal side of the passage members, in a direction intersecting with a longitudinal direction of the passage members.

Abstract: A configuration of a liquid ejecting head enables a stable, continuous ink supply with the off-carriage method, even if a force operates in the direction of joint needle insertion and removal. To this end, a joint opening that accepts insertion of a joint needle on a printing apparatus side is placed at a position closer to a joint face between an ejecting head and a sub tank unit than a positioning opening that engages with a positioning member on the printing apparatus side. Consequently, even if external force is produced due to coupling, the force exerted on the joint face that is a weak portion of an inkjet head may be minimized.

Abstract: A liquid ejection head unit is formed by arranging a plurality of recording element substrates in a first direction. The recording element substrate has an ejection orifice from which a liquid is ejected. The liquid ejection head unit includes: rail portions extending in the first direction and a protective member which is detachably fitted on the rail portions. The protective member is movable along the rail portions between a first position and a second position. The first position allows the protective member to cover whole surfaces of the plurality of recording element substrates. The second position allows the plurality of recording element substrates to be exposed so as to allow a liquid to be ejected from the ejection orifice.

Abstract: A resin molding method includes a first molding step of molding a first molded part and a second molded part in a mold and a second molding step of joining the first molded part and the second molded part. In the first molding step, the second molded part is formed by injecting resin into an area where a first core movable in the first direction and a second core movable in a second direction are engaged. In the second molding step, the second molded part is joined to the first molded part by injecting the resin while the first core is in contact with the second molded part and the second core is removed from the second molded part. Areas where the first core and the second core are located in the first molding step become hollow areas connected to each other and part of ends of the first core in the first direction is not in contact with the second core.
