ABSTRACT:
A paper processing apparatus is provided which includes a sorter for sorting paper discharged from an image forming apparatus into a plurality of bins, each being arranged so that the paper is fed from an upper end of the bin and falls from a lower end of the bin when discharged. A stopper positioned at the lower end of each bin for preventing the paper in the bin from falling, and a stack box for housing the paper dropped from the bin are also provided. A controlling device is provided for controlling the stopper to drop the paper into the stack box by opening the stoppers at substantially the same time after the paper is sorted into the plurality of bins.
