A liquid ejecting head comprising:
- a first head chip including a first nozzle plate formed with nozzles configured to eject liquid in an ejection direction, and having a first direction as a longitudinal direction when viewed in the ejection direction;
- a second head chip including a second nozzle plate formed with nozzles configure to eject liquid in the ejection direction, and having the first direction as a longitudinal direction when viewed in the ejection direction;
- a fixing plate which has a first opening portion exposing at least a part of the first nozzle plate and a second opening portion exposing at least a part of the second nozzle plate, and to which the first head chip and the second head chip are fixed;
- and
- a protection section protruding in the ejection direction from a surface of the fixing plate formed with the first opening portion, wherein
- the first head chip and the second head chip are shifted from each other regarding the first direction and a second direction orthogonal to both the ejection direction and the first direction, and partially overlap each other when viewed in the second direction, and
- the protection section is arranged between the first head chip and the second head chip regarding the second direction.
A liquid ejecting head configured to eject liquid to a medium moving in a transport direction, comprising:
- a first head chip including a first nozzle plate formed with nozzles configured to eject liquid in an ejection direction;
- a second head chip including a second nozzle plate formed with nozzles configured to eject liquid in the ejection direction;
- a fixing plate which has a first opening portion exposing at least a part of the first nozzle plate and a second opening portion exposing at least a part of the second nozzle plate, and to which the first head chip and the second head chip are fixed;
- and
- a protection section protruding in the ejection direction from a surface of the fixing plate formed with the first opening portion, wherein
- the protection section is arranged between the first head chip and the second head chip regarding the transport direction.
A liquid ejecting head unit comprising:
- a liquid ejecting head configured to eject liquid to a medium moving in a transport direction, and includes a first head chip including a first nozzle plate formed with nozzles configured to eject liquid in an ejection direction, a second head chip including a second nozzle plate formed with nozzles configured to eject liquid in the ejection direction, and a fixing plate which has a first opening portion exposing at least a part of the first nozzle plate and a second opening portion exposing at least a part of the second nozzle plate, and to which the first head chip and the second head chip are fixed;
- a protection section protruding in the ejection direction from a surface of the fixing plate formed with the first opening portion;
- and
- a support member for supporting the liquid ejecting head, wherein
- the protection section is detachably attached to the fixing plate by being interposed between the liquid ejecting head and the support member, and is arranged between the first head chip and the second head chip in the transport direction.
