Abstract:
1. A liquid ejecting head unit comprising: a liquid ejecting head having a nozzle forming surface in which a nozzle row made up of a plurality of nozzles that eject liquid is formed; and a head fixing member on which the liquid ejecting head is fixed with intermediate members provided therebetween, wherein the liquid ejecting head includes intermediate member fixing portions to which the intermediate members are anchored and abutted thereto by tightening members, the intermediate member fixing portions being positioned at both ends of the liquid ejecting head with the intermediate members mounted thereto such that a head body of the liquid ejecting head is in between the intermediate member fixing portions, the intermediate member fixing portion and the intermediate member fixed thereto is formed with a plurality of abutting protrusions projecting to a side where the intermediate member abuts the intermediate member fixing portion, at least two of the plurality of abutting protrusions on one side of the liquid ejecting head are provided on the outside of a tightening point, tightened by the tightening members, in the width direction orthogonal to an imaginary line connecting the tightening points on both sides of the liquid ejecting head through the liquid ejecting head, and a gap is formed between the intermediate member fixing portion and the intermediate member at the tightening point before being tightened by the tightening member, while the intermediate member fixing portion and the intermediate member come into abutment with each other at the tightening point after having tightened by the tightening member in a state in which the respective abutting protrusions abut against the other, wherein the intermediate member fixing portion and the intermediate member are anchored by the tightening member, and the intermediate member and the head fixing member are anchored by a head tightening member disposed outside the tightening member in the width direction orthogonal to the imaginary line, the tightening member and the head tightening member extending parallel to each other.
