20100071211LIQUID EJECTING HEAD MANUFACTURING METHOD - A method of manufacturing a liquid ejecting head that ejects a liquid supplied from a liquid storing member through a liquid supply path. The method includes positioning a filter to a first or second supply member by using positioning pins upon disposing the filter between first and second liquid supply paths. The first supply member has the first liquid supply path. The second supply member has the second liquid supply path on the side of one surface of the first supply member to communicate with the first liquid supply path. At least the first supply member and the second supply member are integrated such that a fixed portion is molded by injecting a resin material from an injection portion of a mold at a position where the first and second liquid supply paths are interposed between the positioning pins.03-25-2010
20100214379MANUFACTURING METHOD OF LIQUID EJECTING HEAD, LIQUID EJECTING HEAD, AND LIQUID EJECTING APPARATUS - A manufacturing method produces a liquid ejecting head including first and second flow path members having liquid flow paths that communicate with each other. An integrally-molded member is surrounds the second flow path member on the second flow path member side of the first flow path member to join the first and second flow path members together. A holding process defines a space portion for forming the integrally-molded member in a frame section. The frame section is brought into contact with a contact surface of a recessed portion in the face of the second flow path member opposite the first flow path member, with the first and second flow path members contacting each other such that the liquid flow paths communicate with each other. A molding process fills the space portion with resin, thereby molding the integrally-molded member, and joins the first and second flow path members together.08-26-2010
20110030216METHOD OF MANUFACTURING LIQUID EJECTING HEAD - There is provided a method of manufacturing a liquid ejecting head which includes a head main body having nozzles ejecting a liquid supplied via a liquid supply passage, a first supply member having a first liquid supply passage forming a part of the liquid supply passage, a second supply member disposed on a downstream side of the first supply member and having a second liquid supply passage communicating with the first liquid supply passage and forming a part of the liquid supply passage, a filter disposed between the first and second supply members so as to cross the liquid supply passage, and an integrally molded member fixing the first and second supply members by a resin in a state where the filter is nipped between the first and second supply members. The method includes: disposing the filter in one of the first and second supply members; nipping the filter by the first and second supply members in a state where the filter is sucked, adsorbed, and positioned via a suction hole of the first or second supply member; and forming the integrally molded member in the state where the filter is nipped between the first and second supply members.02-10-2011
20110031641METHOD OF MANUFACTURING LIQUID EJECTING HEAD - There is provided a method of manufacturing a liquid ejecting head which includes a head main body having nozzles ejecting a liquid supplied via a liquid supply passage, a first supply member having a first liquid supply passage forming a part of the liquid supply passage, a second supply member disposed on a downstream side of the first supply member and having a second liquid supply passage communicating with the first liquid supply passage and forming a part of the liquid supply passage, a filter disposed between the first and second supply members so as to cross the liquid supply passage, and an integrally molded member fixing the first and second supply members by a resin in a state where the filter is nipped between the first and second supply members. The method includes: forming a supporting protrusion protruding toward the filter and supporting the filter on an inner wall surface of at least one of the first and second supply members; and forming the integrally molded member in the state where the filter is nipped between the first and second supply members and a pressure difference is caused between the first and second supply members on both sides of the filter so that a pressure is lower on the side of the supporting protrusion.02-10-2011
20110050821LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS - A liquid ejecting head includes a head body that has a nozzle opening for ejecting liquid supplied via a liquid supply path. A first supply member for the liquid supply path has an introduction port for introducing the liquid. A second supply member is positioned on a downstream side of the first supply member. A filter between the first and second supply members crosses the liquid supply path. An integrated molding portion fixes the first and second supply members by resin in a state where the filter is pinched between the first and second supply members. The first and second supply members have pinching portions for pinching the filter therebetween. A wall surface is positioned on one of the first and second supply members and between the filter and the resin to surround an outer periphery of the filter.03-03-2011
20110228021LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS - A liquid ejecting head includes: a head body which ejects a liquid supplied from a liquid storing member via a liquid supply path; a first supply member which is provided with a first liquid supply path forming a part of the liquid supply path; a second supply member which is provided with a second liquid supply path communicating with the first liquid supply path and forming a part of the liquid supply path, and which supplies the liquid to the head body; and a filter which is sandwiched between the first and second liquid supply paths, wherein a sandwiching portion including the first and second supply members and sandwiching the filter includes an inclination portion that is inclined to the downstream side so as to face the outside of the liquid supply path. A liquid ejecting apparatus includes the liquid ejecting head.09-22-2011
20110234700LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS - A liquid ejecting head includes a plurality of head bodies each having a nozzle plate, a flow channel forming substrate having a plurality of pressure generating chambers that communicate with the plurality of nozzles and a manifold that communicates with the plurality of pressure generating chambers, and pressure generating, and a fixation plate having an exposure aperture formed so that the plurality of nozzles are exposed therethrough and on which the plurality of head bodies are fixedly positioned, wherein the edges of the exposure aperture formed on the fixation plate are located in a region opposite the manifold, and a depression is formed on a side of the fixation plate facing the nozzle plate by depressing the edges of the exposure aperture in the region opposite the manifold.09-29-2011
20110316943LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS - The flow path unit includes a flow path unit main body to which the liquid supply needle is attached on the upstream side and including a flow path portion with the liquid flow path formed therein, the flow path portion projecting from a lower face of the flow path unit main body, and a cover member fixed to the flow path unit main body and including a wall portion formed so as to surround the flow path portion, the wall portion having a height that reaches the case member.12-29-2011
