摘要： 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 (304) is attached to a main body (302) formed into a drum shape such that a surface of the cover (304) functions as the suction-holding surface for a paper sheet P. The cover (304) has a plurality of suction apertures (320) formed thereon from which suction apertures (320) the paper sheet P on the suction-holding surface is sucked. The suction apertures (320) are arranged at a certain pitch. A specific suction aperture (320) of them has a narrowing member (322) attached thereto. The suction aperture (320) having the narrowing member (322) attached thereto has the suction pressure lowered. Therefore, by adjusting an arrangement of the specific suction aperture (320) having the narrowing member (322) attached thereto, the suction pressure can be partially controlled within the suction-holding surface.

摘要： A vacuum drum assembly for a printing machine comprises a drum having an array of passageways (40) distributed along its length and around its periphery to permit air to flow from outside the drum to inside the drum in response to reduced air pressure inside the drum, and an array of valve members (52), each valve member being movable between a closed position in which that valve member restricts at least one of the passageways and an open position in which the restriction of that passageway or those passageways is reduced. The arrangement is such that, when a partial area of the drum is wrapped with a sheet of material, at least some of the valves for the passageways adjacent the edges of that area are open, and the valves for the passageways which are not covered by the sheet and are not adjacent the edges of that area are closed. The open area of the drum is regulated such that it is small in regions where there is no paper. Accordingly, the open area of the drum is adapted to the shape and size of the paper and the position of the paper on the drum, whilst minimizing the required suction flow. A duplex printing machine comprises two such vacuum drum assemblies with their drums parallel. The air pressure inside the drums is reduced and the drums are counter-rotated. Material to be printed on is fed to the first drum so that the material can be held on the first drum by vacuum and rotated therewith, and a first print head prints on one side of the material. The material is then released from the first drum in a direction towards the second drum so that the material can be held on the second drum by vacuum and rotated therewith. A second print head then prints on the material on the second drum. The material is then released from the second drum.
