Irradiation light LA and irradiation light LB, which are to be projected toward an irradiation target object 10 from a plurality of irradiation light projection units 4A and 4B, respectively, are corrected so as to be ached with outlines of the irradiation target object 10, which are viewed individually from the irradiation light projection units 4A and 4B. In such a way, a surface of the irradiation target object 10 is coated with irradiation light LA' and irradiation light LB', which are narrower in range than the irradiation light LA and the irradiation light LA. In such a way, the irradiation target object having an arbitrary shape is coated with the plural pieces of irradiation light with high accuracy. |
