The sorter is provided with a plurality of bins arrayed in an upright direction for stacking the sorted sheets, and is provided also with a stapler to staple each sheet stack. The bin is adapted to swing horizontally between a first angular position to stack the sorted sheets and a second angular position to undergo the stapling of the sheet stack by the stapler. The stapler is adapted to move along the upright direction through a plurality of stapling positions, and staples each sheet set at each stapling position.

An aligner aligns the accommodated sheets by pushing the sides of the sheets toward a reference stop wall on each of the bins, and a casing to house the bins is integrated into a unit. The casing is movable in a direction at right angles to a feeding direction of the sheets, and is moved to correspond with the width of the sheets. The home position of the casing is set to a position where the minimum width of sheets are accommodated.
