<p>PROBLEM TO BE SOLVED: To provide a paper sheet post-processing device including a configuration that can correct an attitude of an extra thin paper sheet as an object having been sucked to be subjected to skew correction and improve alignment in stacked paper sheets.SOLUTION: A post-processing device comprises: conveying means 102 and 105 that convey paper P toward a position for performing air suction of the paper sheet; air suction means 106 that is provided at a position for performing air suction of the paper sheet P and performs air suction of a part of the paper sheet P and air suction conveying means 109 that conveys the paper sheet P of which the suction is being performed; skew amount detecting means 103 and 104 that detect skew amounts in a conveyance direction of the paper sheet P conveyed toward the air suction conveying means 109; a rotational driving portion that rotates the air suction means 106 by making a direction perpendicular to a surface of the paper sheet P as a rotary axis; and a control portion 200, whose input side and output side are connected to the skew amount detecting means 103 and 104 and the rotational driving portion, respectively. The control portion 200 calculates a direction for correcting the skew amounts detected by the skew amount detecting means 103 and 104 and a rotation amounts so as to control driving of the rotational driving means.</p> |
