Abstract
A sub-carriage includes a housing unit that houses at least part of each of multiple recording heads, and a head passage opening and an upper opening serving as opening portions through which the housing unit passes. A flow channel anchoring member for anchoring a flow channel member is attached to the sub-carriage so as to span across the aforementioned opening portions, and each of the recording heads is sequentially anchored to the sub-carriage to which the flow channel anchoring member has been attached.
Claims6
A liquid ejecting head unit comprising:
- a liquid ejecting head having a nozzle through which a liquid is ejected;
- a flow channel member inside of which is formed a flow channel for the liquid supplied to the liquid ejecting head;
- a flow channel anchoring member that is manufactured using a material having a higher rigidity than at least the flow channel member and to which the flow channel member is anchored;
- and
- a head anchoring member to which multiple liquid ejecting heads are anchored in a positioned state, wherein the head anchoring member includes a housing portion that houses at least part of each of the liquid ejecting heads and an opening portion that communicates with the housing portion;
- wherein the flow channel anchoring member is attached to the head anchoring member so as to span across the opening portion;
- and
- wherein each of the liquid ejecting heads is anchored to the head anchoring member to which the flow channel anchoring member is attached.
A manufacturing method for a liquid ejecting head unit that includes a liquid ejecting head having a nozzle through which a liquid is ejected, a flow channel member inside of which is formed a flow channel for the liquid supplied to the liquid ejecting head, a flow channel anchoring member that is manufactured using a material having a higher rigidity than at least the flow channel member and to which the flow channel member is anchored, and a head anchoring member to which multiple liquid ejecting heads are anchored in a positioned state, the head anchoring member including a housing portion that houses at least part of each of the liquid ejecting heads and an opening portion that communicates with the housing portion, and the method comprising:
- attaching the flow channel anchoring member to the head anchoring member so as to span across the opening portion;
- and
- anchoring each of the liquid ejecting heads to the head anchoring member to which the flow channel anchoring member is attached.
A liquid ejecting apparatus comprising a liquid ejecting head unit that includes:
