Beschreibung
Zusammenfassung:	A sheet treatment device comprises an unit for counting the number of sheets conveyed piece by piece from an image forming device, an unit for binding a plurality of sheets counted by the counting unit, an unit for conveying a set of sheets bound by the binding unit, an unit for setting a time period associated with the number of sheets counted by the counting unit, an unit, which is disposed at a specified position, for detecting passage of the set of sheets conveyed by the conveying unit, and an unit for judging that sheet jamming has occurred in the event that the passage is not detected by the detecting unit within the time period from the time when the set of sheets begins to be conveyed by the conveying unit.
