Abstract

A paper handling apparatus having a plurality of bins and a chuck unit and a stapler which are movable along the bins and causing the stapler to bind an end portion of a stack of paper sheets which have been received from a copier or similar image forming apparatus, sorted, and then loaded on any one of the bins. The chuck unit has an upper and a lower chuck. After the stapler has bound a stack of paper sheets a push bar independent of the chucks of the chuck unit pushes the end of the stack to return it into the bin. Both the upper and lower chucks are movable up and down. The force which the chucks exert on a stack of paper sheets is controlled in matching relation to the thickness of the stack.
