Abstract
The invention provides a liquid ejecting head alignment apparatus that is used for positional determination and adhesion of nozzle plates and a fixation member, each of the nozzle plates having nozzle openings through which each of a plurality of liquid ejecting heads ejects liquid and further having alignment marks for positional alignment, the fixation member holding the nozzle-plate side of the plurality of liquid ejecting heads. The liquid ejecting head alignment apparatus according to the invention includes: a mask made of a transparent material, the mask having reference marks each of which is aligned with the corresponding alignment mark; a spacer jig that is provided between the fixation member and the mask in such a manner that the reference marks and the alignment marks are opposed to each other with a space being left therebetween, one surface of the spacer jig being in contact with the fixation member; and a bifocal microscope having an optical axis and two optical systems that shares the optical axis, the optical axis being oriented from a face of the mask that is opposite to the spacer jig side thereof toward the alignment mark via the reference mark and the space, on…
