Abstract

A liquid ejecting head unit includes a liquid ejecting head that ejects liquid through a nozzle formed in a nozzle surface, and a holding member to which the liquid ejecting head is attached. Further, in the liquid ejecting head unit, the holding member includes a holder that supports the liquid ejecting head in a predetermine direction which is different from a direction of the nozzle surface of the liquid ejecting head, and a base portion that sticks out from the holder to a side which is parallel to the predetermined direction.

Claims

1. A liquid ejecting head unit comprising:

a liquid ejecting head that ejects liquid through a nozzle formed in a nozzle surface; and

a holding member to which the liquid ejecting head is attached,

wherein the holding member includes;

a holder that supports the liquid ejecting head in a predetermine direction which is different from a direction of the nozzle surface of the liquid ejecting head; and

a base portion that sticks out from the holder to a side which is parallel to the predetermined direction.

2. The liquid ejecting head unit according to claim 1,

wherein the base portion is so provided as to stick out from a position on the holder at an opposite side to the nozzle surface side of the liquid ejecting head.

3. The liquid ejecting head unit according to claim 1,

wherein the holding member is made of a metal.

4. The liquid ejecting head unit according to claim 1,

wherein the base portion includes a first liquid channel which penetrates through in a thickness direction of the base portion and in which liquid is made to flow,

the liquid ejecting head includes a second liquid channel that supplies liquid to the nozzle,

the liquid ejecting head is fixed to the holder with an opening of the second liquid channel facing to the base portion, and

the second liquid channel is connected with the first liquid channel.

5. The liquid ejecting head unit according to claim 4,

wherein a tube member for flowing liquid is inserted into the first liquid channel, and

the tube member is connected with the liquid ejecting head so as to flow the liquid.

6. The liquid ejecting head unit according to claim 5,

wherein the liquid ejecting head includes an insertion portion in which the second liquid channel is open and which sticks out toward the first liquid channel side, and

the second liquid channel communicates with the tube member either by inserting the insertion portion into the inside of the tube member which is inserted into the first liquid channel or by inserting the tube member into the inside of the insertion portion.

7. The liquid ejecting head unit according to claim 5,

wherein a leading portion of the tube member is bent outward centered at the insertion portion and is sandwiched between the liquid ejecting head and the base portion.

8. A liquid ejecting apparatus comprising:

the liquid ejecting head unit according to claim 1.
