ABSTRACT:
A paper sheet material conveying device has a feed roller assembly and a temporary hampering assembly disposed downstream thereof. The sheet material conveying device includes a driven shaft to be rotated by a driving source and a driven roller mounted thereon. The driven roller has an inside diameter larger than the outside diameter of the driven shaft and is mounted rotatably on the driven shaft. When the forward movement of the sheet material fed by the feed roller assembly is hampered by the temporary hampering assembly, the rotation of the driven roller is stopped by the resistance of the sheet material exerted on the driven roller in spite of the rotation of the driven shaft.
