Abstract
A finisher for use with a copier, printer or similar image forming apparatus for stapling or otherwise finishing paper sheets sequentially driven out of the apparatus. A paper sheet is introduced in a stapling section of a stapling device by being switched back, while being accurately guided by a guide member having a sufficient length. The stapling device is movable, independently of jogger fences which position paper sheets, to a particular position which is optimal for the size of stacked paper sheets and the position in which they are used. When a staple error detector detects a stapling error, a discharge path in use is switched over to another path. When a stapled paper stack is discharged, it is deformed in a wave-like configuration in a direction perpendicular to an intended direction of transport to be provided with a certain degree of rigidity. This allows the stapled paper stack to be driven out stably, epecially without being loosened at the discharge side. A jam detector detects a failure in the discharge of paper sheets in a discharging device with accuracy. A stapled paper stack is directly driven out of the stapling device without the intermediary of an exclusive path.
