<P>PROBLEM TO BE SOLVED: To accurately correct a hit position in an object to which liquid jetted from a nozzle is jetted, by correctly determining the displacement amount of the nozzle when a head unit is expanded/shrunk due to temperature change. <P>SOLUTION: Two regulating members 26a, 26b are arranged to sandwich a head holding plate 11 from a paper feeding direction in parallel with a nozzle array 32. The head holding plate 11 holds four black heads 12 and four color heads 13. A positioning pin 27 disposed to the regulating member 26a and an eccentric cam 28 disposed to the regulating member 26b are respectively engaged with cutouts 24a, 24b formed to both end faces with respect to the paper feeding direction of the head holding plate 11 to catch and hold the holding plate 11 with the positioning pin 27 and the eccentric cam 28. Therefore, a portion between the cutout 24a and the cutout 24b of the head holding plate 11 is restricted not to be displaced in temperature change. <P>COPYRIGHT: (C)2013,JPO&INPIT |
