Abstract
In order that the interior of a cap member, in a case where the cap member abuts to a cover member, is allowed to have improved airtightness so that the cap member can sufficiently function, a sealing member is used to seal between the cover member and first and second flow path members for retaining the cover member.
Claims17
A liquid ejection head, comprising:
- a plurality of element substrates each configured to include an ejection opening face on which an ejection opening is formed and an element for ejecting ink through the ejection opening;
- a plurality of first retention members configured to retain the element substrates;
- a second retention member configured to retain the plurality of first retention members;
- a cover member configured to be provided on an upper side of the first retention members so as to extend along a first direction along which the plurality of first retention members are arranged, the cover member including a face on which a cap member covering the ejection opening face is abutted;
- and
- a sealing member disposed in a space surrounded by the plurality of first retention members, the second retention member, and the cover member,
- wherein the sealing member contacts with opposed portions of the first retention members that are adjacent to each other in the first direction to seal between the opposed portions of the first retention members that are adjacent to each other, the opposed portions of the first retention members that are adjacent to each other opposing one another.
A liquid ejection apparatus, comprising:
- a liquid ejection head;
- and
- a cap member,
- wherein the liquid ejection head comprises:
- a plurality of element substrates each configured to include an ejection opening face on which an ejection opening is formed and an element for ejecting ink through the ejection opening;
- a plurality of first retention members configured to retain the element substrates;
- a second retention member configured to retain the plurality of first retention members;
- a cover member configured to be provided on an upper side of the first retention members so as to extend along a first direction along which the plurality of first retention members are arranged, the cover member including a face on which the cap member covering the ejection opening face is abutted;
- and
- a sealing member disposed in a space surrounded by the plurality of first retention members, the second retention member, and the cover member,
- wherein the sealing member contacts with opposed portions of the first retention members that are adjacent to each other in the first direction to seal between the opposed portions of the first retention members that are adjacent to each other, the opposed portions of the first retention members that are adjacent to each other opposing one another.
A method of manufacturing a liquid ejection head, the liquid ejection head comprising a plurality of element substrates each configured to include an ejection opening face on which an ejection opening is formed and an element for ejecting ink through the ejection opening, a plurality of first retention members configured to retain the element substrates, a second retention member configured to retain the plurality of first retention members, a cover member configured to be provided on an upper side of the first retention members so as to extend along a first direction along which the plurality of first retention members are arranged, the cover member including a face on which a cap member covering the ejection opening face is abutted, and a sealing member disposed in a space surrounded by the plurality of first retention members, the second retention member, and the cover member, wherein the sealing member contacts with opposed portions of the first retention members that are adjacent to each other in the first direction to seal between the opposed portions of the first retention members that are adjacent to each other, the opposed portions of the first retention members that are adjacent to each other opposing one another,
- the method comprising:
- a step of retaining the element substrates on the first retention members;
- a step of retaining the first retention members on the second retention member;
- a step of sealing between the first retention members adjacent to each other by the sealing member;
- and
- a step of attaching the cover member on an upper side of the first retention members after the step of sealing.
