  • Patent number: 8246154
    Abstract: A liquid injecting head includes a first supply member and a second supply member in which the liquid supplying path is formed and a filter that is pinched by the first supply member and the second supply member and is disposed in correspondence with the liquid supplying path. In areas that surround the liquid supplying path of the first supply member and the second supply member on the filter side and face each other, filter pinching parts that are brought into contact with the filter are included and concave parts that surround the filter pinching parts are included on the outer side of the filter pinching parts. In addition, the first supply member, the filter, and the second supply member are bonded together by a bonding resin that is formed by flowing into the concave parts of the first supply member and the second supply member.

  • Patent number: 8240833
    Abstract: A liquid ejecting head includes: a first supply member and a second supply member, each of which has a liquid supply passage formed therein; a filter that is held between the first supply member and the second supply member in correspondence with the liquid supply passage; a thermally welded portion that is welded to the filter so that the first supply member melts and soaks into the filter in a region that surrounds the liquid supply passage; a bonded portion at which the second supply member is bonded to the filter by the thermally welded portion; and a bonding resin that is formed by being poured into an outer region between the first supply member and the second supply member and outside the thermally welded portion and bonded portion with respect to the liquid supply passage.

  • Patent number: 7862759
    Abstract: A method of manufacturing a liquid ejecting head and a supply member having a plurality of liquid supply passages is provided. The supply member includes first and second supply members in which liquid supply passages are provided and filters provided between the first supply member and the second supply member. The method includes: preparing a connected filter formed of a plurality of filter element portions corresponding to the plurality of liquid supply passages and a connecting portion that connects the plurality of filter element portions; in a state where the filter element portions of the connected filter are held between the first supply member and the second supply member, charging molten resin from a position corresponding to the connecting portion of the connected filter to separate the connecting portion; and, during the charging, molding.

  • Publication number: 20090225142
    Abstract: A liquid ejection head ejecting a liquid contained in a liquid reservoir from nozzle apertures through a plurality of liquid supply channels includes a first liquid supply member and a second liquid supply member that define the plurality of liquid supply channels. A filter is disposed between the first supply member and the second supply member. The filter includes a plurality of filter portions corresponding to the respective liquid supply channels and at least one joining portion disposed across the region between the filter portions to join the filter portions to each other. The first supply member and the second supply member are bonded together at the region corresponding to the joining portion of the filter with a resin joint that is made of a resin penetrating the joining portion.
