ようにしたことを特徴とする用紙搬送装置。 A vacuum-type transport that has a suction belt that attracts and transports paper using negative pressure, and a roller that grips and transports the paper conveyed from the vacuum-type transport between a drive roller and a pinch roller that are arranged opposite to each other. In the paper conveying device, the diameter of the drive roller is set to be higher than the circumferential speed of the vacuum transport and the roller. The drive roller is formed so that the circumferential speed of the drive roller is gradually decreased from the center of the paper transport path that connects the paper transport path to both ends in the width direction, and the circumferential speed of the drive roller is gradually decreased from the center of the paper transport path to both ends in the width direction. A paper conveyance device characterized in that the paper conveyance device is configured to reduce the amount of paper.
