PROBLEM TO BE SOLVED: To provide a paper sheet post-processing device properly stacking paper, while reduced in cost. SOLUTION: The paper stacking device includes: a first and a second guide plates 54a and 54b, having inclined guide surfaces to a vertical plane, taking an open state having a gap of a first interval perpendicularly to their inclination, and a closed state having a second interval that is narrower than the first interval; a stacker 80 provided stand-by below the first and the second guide plates 54a and 54b to receive the end of the paper sheet in the carrying direction; and a carrying guide member 78b to support the lower surface of the paper sheet for holding a paper sheet bundle in a vertical position. Another paper sheet carried subsequently to the paper sheet received by the stopper 80 is guided with the first and the second guide plates 54a and 54b taking the closed state. Then they take the open state to drop the stacked paper sheet from the gap between the guide plates onto the preceding paper sheets. COPYRIGHT: (C)2009,JPO&INPIT
