<p>PURPOSE:To realize high-speed and stable arrangement even if size of paper is different by taking the time from the completion of paper discharge to the contact of arrangement member with end face of paper above a fixed period of time even if moving distance of the arrangement member is changed. CONSTITUTION:In a certain period of time TA after a pin paper discharge sensor 14 detects discharge of paper P, an arrangement bar 4 starts to move from the home position H.P and contacts end of paper P and moves until paper P contacts a fence 2. After that, the arrangement bar 4 reciprocates in the width of 3 to 10mm once or twice at the position and returns to the home position H.P. Since travel distance of the arrangement bar 4 differs depending on size of paper P, time TA is depending on size of paper. When the size of paper P is large, time TA is prolonged, and when the size of paper P is small, time TA is shortened. Time TB from the completion of discharge of paper to the time when the arrangement bar 4 contacts paper P is made constant.</p> |
