Abstract: In the invention, pipes and the like are guided in parallel to a second horizontal direction according to collective movements of printing bar units while being stored and protected by a protecting/guiding member arranged outside and adjacent to a body frame. In this way, breakage of the pipes and the like during the collective movements of printing bar units is reliably prevented. Moreover, the pipes and the like stored in the protecting/guiding member move outside the body frame and are not present inside the body frame. As a result, a work space can be secured without being limited by the collective movements of the printing bar units to the maintenance space.

Abstract: In order to provide an illumination technique capable of illuminating an object in a plurality of illumination modes with a reduced size and at low cost, an illumination device comprises: a light emitter including first light emitting elements and second light emitting elements configured to emit light toward the object; an optical system including a first optical element configured to change a light distribution of light emitted from the first light emitting elements to a first light distribution, the optical system introducing light emitted from the second light emitting elements with a second light distribution different from the first light distribution to the object; and an illumination controller configured to mutually independently control the light emission of the first light emitting elements and the second light emitting elements.

Abstract: A reference original having a reference image is prepared and photoelectrically read with an image reader. The image thus obtained includes a true image and a false image which is called as a ghost or a flare. The relationship between the true image and the false image is detected. Then, an objective image to be reproduced is photoelectrically read with the image reader. The image thus obtained has a true image and a false image of an objective. The false image is eliminated using the relationship detected for the reference original.
