A sheet aligning device including a pair of side walls located parallel to each other and defining therebetween a space for stacking a plurality of sheets. At least one of the side walls is movable in reciprocatory movement widthwise of the sheets stacked between the side walls to force the sheets against the other side wall so as to align the sheets widthwise thereof which is perpendicular to the direction in which they are delivered. The sheet aligning device includes at least one sensor for sensing the magnitudes of displacements of the sheets widthwise thereof and producing an output for adjusting at least one of the frequency, speed and stroke of the reciprocatory movement of the at least one side wall in accordance with the magnitudes of the displacements. |
