PROBLEM TO BE SOLVED: To provide a sheet post-processing device capable of miniaturization of the device and simplification of a drive mechanism.SOLUTION: A sheet post-processing device includes: a fixed tray 21; a swing tray 22; a CD reference plate 29 capable of moving on the fixed tray 21 in an alignment direction from a back surface side of the device to a front surface side; and a CD reference plate 12 capable of moving on the swing tray 22 in the alignment direction and having a projection 12a engaged with the CD reference plate 29. When aligning a sheet on the fixed tray 21, the swing tray 22 becomes an inclined posture and the CD reference plates 12 and 29 are engaged, and the CD reference plate 29 moves to the device front surface side together with the CD reference plate 12 according to the movement of the CD reference plate 12. After the completion of alignment, the sheet on the fixed tray 21 is conveyed onto the swing tray 22, and as the swing tray 22 transits to a horizontal posture raised with respect to the inclined posture, the engagement is released, and the sheet on the swing tray 22 is pushed to the device front surface side only by the CD reference plate 12 moving to the device front surface side and accommodated in a front surface tray 51. |
