PROBLEM TO BE SOLVED: To prevent a miscopy and improve reliability by moving a sheet delivery aperture from a current bin position to a proof tray, and calculating a bin travel time from the current bin position to the proof tray for comparison with a time for a sheet to arrive at a bin tray inlet after receipt of a sheet delivery signal. SOLUTION: A bin lift mechanism is controlled with a bin home sensor 48 so as to position a proof tray 40 at a sheet delivery position. Furthermore, the travel time of a bin from a bin tray 41 currently at a sheet delivery aperture to the proof tray 40 is calculated so that the proof tray 40 is positioned at the sheet delivery aperture for the bin tray 41, when a transcribed sheet as fed is invalid. At the same time, a time tB for the leading end of the transcribed sheet to arrive at a sensor at a bin tray inlet after the confirmation of the invalid sheet is calculated. When tA is shorter than tB, the bin is made to travel to the proof tray 40. When the relationship of tA<tB is not satisfied, a warning is displayed on an operation part. According to this construction, the mixed loading of the invalid sheet onto the bin tray 41 can be properly prevented. |
