a pair of cutouts upstream from the leading end support in the feeding direction; and
a pair of sheet restrictors configured to slide in the pair of cutouts in a width direction orthogonal to the feeding direction to regulate a position of the bundle of sheets on the sheet stacker in the width direction; and
