Abstract: A paper handing apparatus having a plurality of bins, a chuck unit and a stapler unit movable up and down along the bins, and a sorting unit. The sorting unit distributes a number of paper sheets received from a copier or similar image forming apparatus to the bins, while the stapler unit binds an end portion of each of the stacks of paper sheets loaded in the individual bins. The stapler is movable between and lockable at a position for binding a paper stack and a position for supplying staples. The stapler unit is removable from the sorting unit. Doors such as a stapler door are provided on the housing of the apparatus. When a door other than the stapler door is opened when the stapler is performing a stapling operation, the stapling operation is continued until it completes.

Abstract: A paper handling apparatus having a plurality of bins, a paper positioning device for positioning paper sheets which are sequentially distributed to the bins, and a stapler for stapling the paper sheets stacked on the bins. A controller causes the paper positioning device to position the paper sheets even after the latter has been stapled by the stapler.

Abstract: A paper positioning device having a paper positioning member which is pivotable in abutment against one edge of a paper sheet loaded on a receptacle for moving the paper sheet to a positioning position for thereby positioning the paper sheet. By a simple mechanism and control, the movement of the paper positioning member is slowed down at the positioning position and accelerated until the positioning member reachines it. The paper positioning member performs a pivoting movement twice while a drive shaft associated therewith performs a reciprocating movement once. The device is, therefore, no only durable but also positions paper sheets efficiently and positively without damaging the paper sheets.

Abstract: A paper handling apparatus for use with a copier, printer or similar equipment for sorting a number of paper sheets sequentially driven out of the equipment to prepare paper stacks and binding the paper stacks. The apparatus has a plurality of bins, a sorter for sequentially distributing the paper sheets to the individual bins, a mechanism for positioning the paper sheets distributed to the bins, and a stapler for stapling the paper sheets positioned on the bins. The sorter and the stapler are operable simultaneously with each other. The stapler acts on only those bins which are loaded with paper sheets associated with the last document without exception, while not acting on those bins which are loaded with paper sheets associated with the last document but are loaded with only a single paper sheet. The bin on which the stapler is to act is located at least two bins above the bin where the paper sheets are to be positioned.

Abstract: An electronic copier having an automatic document feeder and a sorter and selectively operable in a multi-job mode for continuously copying a plurality of groups of documents which differ in copying condition from each other. Single display means displays any desired job data. In response to a copy start signal, single display means displays job data associated with one group of documents which are to be copied.
