Abstract: There are provided an image reading device and a printing apparatus that can reduce an influence of the shadows of suction holes. Suction holes, which are used to suck a sheet, are arranged on the peripheral surface of a drum that transports the sheet. The suction holes are arranged in grooves that are formed along a direction orthogonal to a transport direction. Accordingly, since an influence of the shadows of the suction holes can be reduced even in a case in which density unevenness is inspected on the basis of a read image, the false detection of density unevenness can be prevented.

Abstract: A paper conveyance apparatus includes: a drum that conveys a paper by winding the paper around an outer peripheral surface thereof and being rotated; a press roller that presses a surface of the paper at a predetermined position on the outer peripheral surface of the drum and brings a reverse surface of the paper into contact with the outer peripheral surface of the drum; and a back tension providing unit having an adsorption surface by which the surface or the reverse surface of the paper is absorbed, the back tension providing unit being configured so that provides the paper with a back tension by causing the adsorption surface to adsorb the surface or the reverse surface of the paper with an adsorption force which decreases from the center in a width direction of the paper toward both ends in the width direction of the paper.

Abstract: When a distal end of a paper is gripped by a gripper of a chain gripper and transported, the paper is transported while being in sliding contact with a guide surface of a guide plate. On the guide surface of the guide plate, a groove is formed along a traveling route of the gripper, and by a claw member entering the groove, a height of the distal end of the paper gripped by the gripper and a height of the guide surface are matched.

Abstract: An aspect of the present invention provides an inkjet recording apparatus, including: a conveyance device which has a moving suctioning surface and which conveys a cut sheet medium by suctioning the medium on the suctioning surface, a concavoconvex pattern being formed in the suctioning surface by arranging recess sections regularly in the suctioning surface, and suction holes each having an opening smaller than a size of openings of the recess sections being formed inside the recess sections; and a recording head which forms an image by ejecting ink by an inkjet method onto a surface of the medium which is conveyed by the conveyance device. According to the aspect, it is possible to prevent floating and wrinkling of the medium during conveyance, and an image of high quality can be recorded.
