<p>PROBLEM TO BE SOLVED: To prevent damage to sheets and the interruption of a process by releasing a stitching process when the number of sheets recognized by a number of sheet recognizing means exceeds the stackable number of sheets, and distributively stacking the sheets to another sheet stacking means. SOLUTION: When a counter T judges that the number of bin stacked sheets is equal to the number of bin stackable sheets (n) or that M copies are completed (S710), an event flag (f) is set to 1 (S711). Sheet bundles stacked on the bins of an upper bin module are bundle-conveyed to a stack unit, all sheet bundles of the upper bin module are bundle-conveyed, and the sheet bundles are stacked on a stack tray (S712). The sheet bundles stacked on the bins of a lower bin module are bundle-conveyed to the stack unit, all sheet bundles of the lower bin module are bundle-conveyed, and the sheet bundles are stacked on the stack tray (S713).</p> |
