MEDIUM-HOLDING DEVICE, MEDIUM-CONVEYING DEVICE, AND INKJET RECORDING DEVICE

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 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.

主权项

1. A medium-holding device holding a sheet-shaped medium by suction, comprising:
a main body having a sucking part; a sucking device which sucks an inner side of the sucking part; a sheet-shaped cover which is attached to the main body and covers the sucking part to configure a suction-holding surface of the medium; a plurality of suction apertures formed to have the same diameter on the cover; and a narrowing member individually provided to a specific suction aperture of the plurality of suction apertures and for narrowing the specific suction aperture, the narrowing member including a narrowing flow path which is provided on a back surface of the cover and in communication with the specific suction aperture to narrow the specific suction aperture, wherein the narrowing member abuts on the main body when the cover is attached to the main body.
