When the coating object area is positioned on the suction table, the film is stopped and is mounted on the suction table, and is further provided with tension in the longitudinal direction to eliminate slacks or the like, but, curl is caused in the both side end regions in the coating object area. Therefore, the coating object area is mounted on the suction table, and at the same time, the curl correction bars disposed on the both sides of the suction table are moved to the curled portions of the coating object area, and then the curled portions are pressed against the suction surface of the suction table to thereby perform the curl correction. Further, in the coating process with the UV-curing coating material, the UV light from the UV light source formed integrally with the coating head is applied to cure the material. In the vacuum suction section, as the destination, the bubbles or the like in the coating head are sucked. When the suction of the coating head is not performed, the UV shutter is moved by the suction section air cylinder to block the suction port of the vacuum suction section. Thus, the inside of the vacuum suction section is shielded from the UV light.

Inkjet coating device and inkjet coating method

A film paid out from a feed side film roll is conveyed so that an application target area of the film is located on a suction table in an application portion. Image-capturing cameras are disposed so as to be adjacent to ink-jet application heads so that one application head and one image-capturing camera are integrated with each other in terms of position of installation to form one application head unit portion. Each application head unit portion is moved above the suction table by a three-dimensionally movable XYZ-direction driving unit. A position where application will be performed next is image-captured by each of the image-capturing cameras in advance during the applying operation due to each of the application heads. A result of image capturing by each of the image-capturing cameras is processed by an image processing unit.
