Abstract:
PROBLEM TO BE SOLVED: To align edges in the cross direction of printed paper sheets on a discharge paper sheet table regardless of the paper sheet size by providing on a discharge paper sheet side fence an inclined part which protrudes to the center in the cross direction of the paper sheet and makes both edges in the cross direction of the paper sheet warp upward.
SOLUTION: Ribs 204B to 204D and 205A to 205D are protruding to the center of a printed paper sheet S in the cross direction at the lower part of discharge paper sheet side fences 201, 202, corresponding to the paper sheet stacking curface on a discharge paper sheet table 52', in proportion to the lower part from the upper part of the discharge paper sheet fences 201, 202. Thus rids 204B to 204D and 205A to 205D include an inclined surface or an inclined ridgeline facing toward the paper sheet stacking surface on the lower part of discharge paper sheet side fences 201, 202, while both edges in the cross direction is thrusted up and the posture of the shape of the printed paper sheet S in the cross direction is corrected to be in a reverse arc shape by overlapping both edges in the cross direction of the printed paper sheet S dropped on the paper sheet stacking surface on the discharge paper sheet table 52'.
