Abstract
A holding member provided in a liquid ejection apparatus is attached to a receiving member and includes a capturing portion capturing a supply member so as to hold the supply member. The capturing portion is displaceable while the holding member is attached to the receiving member.
Claims14
A liquid ejection apparatus comprising:
- a supply member that includes a supply opening and is constructed to supply a liquid from the supply opening;
- a liquid ejection head that is constructed to eject a liquid;
- a receiving member having first and second ends, the receiving member being connected to the liquid ejection head at the first end, the receiving member being constructed to receive the supply member at the second end, and the receiving member further being constructed to supply the liquid supplied from the supply member to the liquid ejection head in a case where the second end of the receiving member receives the supply member;
- and
- an elastic holding member that is attached to the second end of the receiving member, wherein one end of the elastic holding member is provided with a first insertion opening into which the supply member is inserted and is provided with a film member for blocking the first insertion opening, and wherein another end of the elastic holding member is provided with a second insertion opening communicating with the first insertion opening and into which the second end of the receiving member is inserted,
- wherein an inner diameter of the second insertion opening is smaller than an outer diameter of the second end of the receiving member at a position where the second end of the receiving member is inserted to the second insertion opening of the elastic holding member, so as to urge the film member in a direction in which the first insertion opening is blocked by deformation of the elastic holding member in a case where the second end of the receiving member is inserted to the second insertion opening of the elastic holding member.
