<p>PURPOSE:To provide compactness in total height of a sorter by forming a collision surface into a step-differenced shape having a plurality of recessed/ protruded parts, and relieving air in an air layer between sheets, loaded straightened on a bin, to the outside from a void in the recessed part. CONSTITUTION:A stopper wall is vertically provided into an integral unit in one side surface of a bin 41, and an internal side surface 41DA of the stopper wall is a collision surface which properly arranges paper with its side end edge in collision. This collision surface is formed into a step-differenced shape, having a plurality of recessed/protruded parts, to bring the protrusive part into contact with a one side end edge of paper and taking refuge of the recessed part from the side end edge of the paper to form a void. Since air in an air layer, formed between the fellow surfaces of a paper bundle loaded straightened sheet by sheet on the bin 41 by swiveling a straightening bar, escapes to the outside from the void of the recessed part, the following paper is prevented from riding over the collision surface to escape in disorder outside the bin by increasing a stack thickness swollen of paper loaded on the bin 41.</p> |
