PROBLEM TO BE SOLVED: To provide a sheet post-processing device in a device configuration where a processing tray and a stack tray are disposed on the upper and lower sides, capable of aligning a sheet carried in on both trays in correct attitudes at correct positions, and simple in structure for alignment.SOLUTION: A paper discharge port of a paper discharge passage, a processing tray and a stack tray are formed in order with a vertical level difference. Aligning means for aligning a sheet guided from the paper discharge port to the processing tray and a sheet transferred from the processing tray to the stack tray includes: a pair of aligning members; width direction shift means for moving the position thereof in the sheet width direction; and height direction shift means for moving the position thereof in the sheet loading direction. By the height direction shift means, the aligning members are selectively positioned at a first height position for regulating the width direction position of the sheet supported on the processing tray and a second height position for regulating the width direction position of the sheet supported on the stack tray. |
