Abstract: The present invention provides a medium-holding device capable of setting a suction pressure for each of various areas within a suction-holding surface, a medium-conveying device, and an inkjet recording device. In an embodiment of the invention, a cover is attached to a main body formed into a drum shape such that a surface of the cover functions as the suction-holding surface for a paper sheet. The cover has a plurality of suction apertures formed thereon from which suction apertures the paper sheet on the suction-holding surface is sucked. The suction apertures are arranged at a certain pitch. A specific suction aperture of them has a narrowing member attached thereto. The suction aperture having the narrowing member attached thereto has the suction pressure lowered. Therefore, by adjusting an arrangement of the specific suction aperture having the narrowing member attached thereto, the suction pressure can be partially controlled within the suction-holding surface.

Abstract: Mirror sequential data supplied from an RIP are temporarily stored as divided data in memory banks of an intermediate memory. Thereafter, the stored mirror sequential data are read in blocks. Then, a transposition processor transposes a matrix of the mirror sequential data into frame sequential data, and supplies the frame sequential data to a DMD controller.

Abstract: A photosensitive material (for example, a glass substrate coated with a photoresist) is exposed to light in a predetermined pattern by illuminating the photosensitive material with exposure light by an exposure head which emits light that has been modulated by a spatial light modulation device. The exposure head and the photosensitive material are moved in a sub-scan direction at least twice for each photosensitive material. The operation of the spatial light modulation device is controlled in each of sub-scan movements to form an exposed area, of which the exposure amount is at least at two different levels, in the photosensitive material.
