Abstract: A sorting apparatus which has a nest of a plurality of sheet receiving bins supported on a sorting support frame, each bin with a sheet output end and a sheet input end, the plurality of bins being pivotally mounted at their output end about the same pivot point on the support frame such that the output end of each bin is at a level higher than its input end so that the bins slope upwardly for uphill stacking of sheets as they are inserted. The bins are spaced relatively close together at the input end and relatively far apart at the output end. The apparatus is also provided with a rotary shifting member to sequentially pivot the bins about their pivoting mount to index the bins past the fixed feed throat for sheet insertion and as the bins are indexed past the fixed feed throat the rotary shifting member widely spaces adjacent bins to provide sheet entry for successive bins when positioned opposite the feed throat while the input ends of the bins are nested close together on either side of the sheet entry.
