Abstract
In 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. Thereby, even 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) so that the jogging action and sheet fence adjustment can be achieved by a common structure and a common drive unit.
