<P>PROBLEM TO BE SOLVED: To perform ultraviolet irradiation in both outward and return movement of a print head while suppressing increases in an installation space and a loaded weight at minimum in arranging an ultraviolet irradiation source on a print head conveying means. <P>SOLUTION: The recorder 1 includes: a mounting table 2; a print head 3 which discharges ink cured by exposure of an ultraviolet ray; a carriage 4 which reciprocates the print head 3 to one side and the other side of a scan direction; a plurality of nozzle holes 9 arrayed on an end surface of the print head 3 on a mounting table 2 side along an orthogonal direction orthogonal to the scan direction; a plurality of light emitting elements 11 which are arrayed over the orthogonal direction opposite to the end surface of the print head 3 and generates the ultraviolet ray; and an optical path switching mechanism 20 which is arranged opposite to the print head 3, and switches a terminal part of an optical path 30 of the ultraviolet ray between a first optical path 31 passing through the one side of the scan direction of the print head 3 and a second optical path 32 passing through the other side of the scan direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
