A post-processing device includes: a loading section that has a loading surface directed obliquely upward and in which a recording medium is loaded on the loading surface in a state where one end of the recording medium is directed downward; a supporting section that supports the one end of the recording medium loaded on the loading surface; and a correcting section that has a facing surface facing toward the loading surface and that corrects deflection of the recording medium by coming into contact with the recording medium in a posture in which a lower end portion of the facing surface approaches closer to the loading surface than an upper end portion from a side of the recording medium, which is loaded on the loading surface, opposite to the loading surface and by thereafter coming into contact with the recording medium while moving such that the upper end portion approaches the loading surface in a state where the lower end portion is in contact with the recording medium.

A post-processing device includes: a loading section that has a loading surface directed obliquely upward and in which a recording medium is loaded on the loading surface in a state where one end of the recording medium is directed downward; a supporting section that supports the one end of the recording medium loaded on the loading surface; a transporting mechanism that transports a plurality of recording media transported one by one toward the loading section by shifting and stacking the recording media in a transport direction, and sets an amount of shift of the recording media on the basis of a predetermined condition; and a transporting section that bends each of the plurality of recording media transported from the transporting mechanism by applying a transport force to an upper end of each of the recording media opposite to the one end in a state where the one end is in contact with the supporting section, and separates one by one the recording media and loads the recording media on the loading surface.

In accordance with an embodiment, a sheet processing apparatus comprises a processing tray, a longitudinal alignment mechanism, a horizontal alignment mechanism and an interlocking mechanism. The processing tray can stack a sheet. The longitudinal alignment mechanism includes a rotatable paddle. The longitudinal alignment mechanism can align the sheets stacked on the processing tray in a sheet conveyance direction. The horizontal alignment mechanism includes a horizontal alignment plate movable in a sheet width direction orthogonal to the sheet conveyance direction. The horizontal alignment mechanism can align the sheets placed on the processing tray in the sheet width direction. The interlocking mechanism interlocks the paddle in the sheet width direction in synchronization with the movement of the horizontal alignment plate in the sheet width direction.

A paper delivery device includes a shift frame movable in a second direction perpendicular or substantially perpendicular to a first direction along which paper is delivered to outside, a driver that moves the shift frame in the second direction, a drive roller with a first outer peripheral surface extending in the second direction and supported by the shift frame such that the drive roller is rotatable about a first shaft parallel or substantially parallel to the second direction, a first driven roller with a second outer peripheral surface extending in the second direction and contactable with the first outer peripheral surface at a first contact position, the first driven roller supported by the shift frame such that the first driven roller is rotatable about a second shaft parallel or substantially parallel to the second direction following the rotation of the drive roller, the first driven roller being rotated in a state where the paper is nipped between the first outer peripheral surface and the second outer peripheral surface thus transporting the paper in the first direction, and a second driven roller with a third outer peripheral surface extending in the second direction and contactable with the first outer peripheral surface at a second contact position downstream of the first contact position in the first direction, the second driven roller being supported by the shift frame such that the second driven roller is rotated about a third shaft disposed parallel or substantially parallel to the second direction following the rotation of the drive roller, the second driven roller being rotated in a state where the paper which is nipped between the first outer peripheral surface and the second outer peripheral surface is nipped by the first outer peripheral surface and the third outer peripheral surface thus transporting the paper in the first direction.

A sheet processing apparatus includes a controller configured to control operations of the pair of aligning members such that a sheet bundle disposed on a first stacking portion is aligned by the pair of aligning members of the pair of aligning members at a position shifted to a side of one aligning member in a width direction perpendicular to the discharge direction of a sheet with respect to a sheet discharge range in which a sheet is discharged at the time of discharging the sheet from a discharge portion, and, before the aligned sheet bundle is discharged to a second stacking portion by a bundle discharge portion, the other aligning member of the pair of aligning members is moved to the outside of the sheet discharge range in the width direction.
