members 11 on the respective sides of the horizontally disposed two conveying rollers 9 the restriction member 14 is pivotably attached to the horizontal shaft 12 in the same way as the claw member 11 also the restriction member 14 extends to nearly the same level as the lowermost portion of the conveying roller 9 attached to the next under horizontal shaft 12 and has such a form that when pivoted to a predetermined position in the counterclockwise direction in fig2 the outer surface of the restriction member 14 comes in substantially agreement with a right lower surface of the conveying roller 9 accordingly a paper sheet in the process of being transferred to the bin 7 is kept from rising by the conveying rollers 9 and the restriction members 14 and consequently eliminated from being waved next operation of the sorter will be described a paper sheet is supplied from the discharge portion of the main body a or from the right upper portion in fig1 and transferred to the guide plate 5 when the sorter is set in the non sort state the guide plate 5 is held in a position shown by imaginary lines in fig1 and the paper sheet is transferred directly to an uppermost bin 7 through the discharge roller.
