<p>PROBLEM TO BE SOLVED: To prevent a lowering of productivity caused by erroneous recognition by preventing erroneous recognition in detecting a full stack of sheets. SOLUTION: A sheet handling device has a sheet stacking tray 18 that can be elevated, a lower reaches discharge roller pair 17 for discharging sheets to the stacking tray 18, and a distance measuring sensor 54 for detecting the uppermost face of the sheets stacked on the stacking tray 18. The stacking tray 18 is put in elevating action plural times, and the uppermost face of the stacked sheets is detected every elevating action or after the completion of elevating action. Only after detecting the uppermost face of the stacked sheets to be the specified height or higher continuously plural times, it is judged that the sheets are stacked to the full, and the device is stopped.</p> |
