Abstract:
1. An ultraviolet irradiation unit which is mounted on an inkjet printer for performing desired printing on a printing medium by sticking ink to the printing medium and irradiating ultraviolet rays to the ink so as to cure the ink, the ultraviolet irradiation unit comprising: an ultraviolet irradiation means for irradiating ultraviolet rays to the ink which is stuck to the printing medium; an ink mist sucking and removing device for sucking and removing ink mist floating in an upper vicinity of the printing medium; wherein the ink mist sucking and removing device comprises; wherein air in the upper vicinity of the printing medium is sucked through the suction port by the blower fan so that the air is passed through the air filter and the ink mist included in the air is removed by the air filter and becomes a cleaned air, the cleaned air discharged from the discharge port is blown to the ultraviolet irradiation means, and forms airflow which is passed through surroundings of the ultraviolet irradiation means and is directed toward the printing medium, and a movement control device for controlling an inkjet head and the printing medium, wherein ink ejection from the inkjet head and rotation of the printing medium are synchronously controlled and ultraviolet rays are irradiated from the ultraviolet irradiation device, wherein the printing medium has a surface in a three-dimensional shape.
