Abstract
A recording head unit includes a first line head and a second line head in which nozzles are provided in an X-axis direction. The first line head is arranged on one side of the second line head in a Y-axis direction intersecting the X-axis direction. The first line head includes a first windbreak member. The second line head includes a second windbreak member. A length by which the first windbreak member protrudes is smaller than a length by which the second windbreak member protrudes.
Claims11
A recording head unit, comprising:
- a first line head and a second line head in which a plurality of nozzles for ejecting liquid are provided in a nozzle row direction, wherein
- the first line head is arranged on one side of the second line head in a head row direction intersecting the nozzle row direction,
- the first line head includes a first windbreak member, on the one side in the head row direction, along a width of the first line head in the nozzle row direction, the first windbreak member protruding, in a liquid ejection direction in which the liquid is ejected, with respect to a nozzle opening surface at which the plurality of nozzles included in the first line head are open,
- the second line head includes a second windbreak member between the second line head and the first line head along a width of the second line head in the nozzle row direction, the second windbreak member protruding, in the liquid ejection direction in which the liquid is ejected, with respect to a nozzle opening surface at which the plurality of nozzles included in the second line head are open, and
- a length by which the second windbreak member protrudes is smaller than a length by which the first windbreak member protrudes.
