Abstract: A sheet processing device in the form of an offset stacker, a sheet fence (103, 104) is provided on a side of sheets (S) to be processed stacked on a stack tray (3) opposite from a jogger (101, 102) so that the sheet fence accurately defines a final offset position of the sheets. When a transient offset position at which the sheets are stacked on the stack tray varies from one sheet to another, the side edges of sheets selected for offset stacking can be lined up without fail owing to the jogging action of the jogger and the supporting action of the sheet fence. A pair of joggers may be arranged on either side of the sheets, along with a pair of corresponding sheets fences on the opposing sides. The jogger and sheet fence on a same side may be supported by a common moveable frame (107, 108).

Abstract: A bookbinding device includes a plurality of annular binders corresponding to binding holes. A part of an annular binder is inserted into a binding hole to be engaged, and by virtue of the insertion of the annular binder into the corresponding binding hole, the sheet bundle is bound to be provided as a booklet. Respective ends of binding members engage with each other, whereby the binding members are unified. The binding members are disposed so as to be aligned and constitute respectively binding member units which can be separated one by one. The pairs of the binding members are located in sequence so as to correspond to the binding holes to be pushed and moved and, thus, to be inserted through the binding holes. The respective ends of the binding members then engage with each other, whereby the binding members are unified.

Abstract: A sheet sorter delivers sheets introduced seriatim from a host unit such as a copier onto a plurality of removable stationary sheet receiving trays through its pivotable sheet guide and discharge mechanism having four pivotal axes. The sheet guide and discharge mechanism is pivotably supported at its one end on two fixed pivotal axes so that the mechanism can be pivotally swung up and down about the two fixed pivotal axes. At the other end of the sheet guide and discharge mechanism, which is unsupported, are disposed the other two pivotal axes and sheet discharge rollers. The swinging motion of the mechanism is achieved by a Geneva drive mechanism including a first driving motor so that the level of the sheet discharge roller is sequentially shifted to be aligned with each of the tray levels and the sheets are seriatim sorted onto the respective trays. The sorter has a second driving motor for driving the sheet discharge rollers.
