<p>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 back tension providing means having an adsorption surface by which the surface or the reverse surface of the paper to be wound around the drum is absorbed, the back tension providing means being configured for providing 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.</p> |
