<p>PROBLEM TO BE SOLVED: To reduce the extent of operating noise as securing sufficient operational force to be enough for such an extent that a flapper is made into a state of being opened within the appointed time, and a sheet is surely sortable to the specified tray. SOLUTION: As for driving control to two operating means 36 and 37 for four flappers 81 to 84, first of all, operations of two connecting members 38 and 39 lying between these plural flappers and operating means are detected, and on the basis of the detection signals, this control for slowing down an operating speed is carried out. Further, in order to make it into such an operating force as different by a tray position specified for paper discharging, this driving control whose operating force is made larger as far as at the time of its discharge to a tray on the downstream side is carried out in this way.</p> |
