<p>PROBLEM TO BE SOLVED: To favourably discharge and load sheets to a sheet loading means as well as to prevent bending of deformed parts of the sheets. SOLUTION: A control device lowers a stack tray first until input of a detection signal stops in the case when input of the detection signal does not stop even if a stack tray 200 is lowered by specified quantity after there is input of the detection signal from a paper surface detection sensor S205. Constinuously, it raises it until the detection signal is input. Continuously, a series of correction control to lower the stack tray 200 until the detection signal stops is carried out. Consequently, it is possible to improve consistency of sheets P on the stack tray 200 by eliminating a deformed part Pa of the sheets P.</p> |
