PURPOSE:To improve the stack performance of paper to be folded onto a stacker table by reducing the friction factor of a pressboard in a vane of a stopper wheel and providing the paper pressing force to said pressboard through a resilient member. CONSTITUTION:When folding a paper 7, a positioning member 37 is rotated by predetermined amount in predetermined direction to position a stopper wheel 21 and a guideboard 22 at the position corresponding with the paper width and to rotate a rotary shaft 23 under this state thus to function a printer. Consequently, even if there is an inflated portion at the folding section (opposite upper end sections) of paper 7 to be discharged to the lower section upon completion of printing, said inflated portion is pressed and corrected by a pressboard to be energized through a resilient board provided on a vane 24 of the stopper wheel 21. Since the pressboard is made of low friction factor material, the paper 7 will never slip when pressing to perform folding reliably resulting in good stack performance. |
