<p><P>PROBLEM TO BE SOLVED: To provide a sheet processing device where the operation rate of a device main body A is raised and work man-hour accompanying the rearrangement of full stacking of sheets is reduced by delaying time to decide the full stacking without making a stacking state unstable or tumbledown when stacking the sheets P having different size in the same stack tray 18. <P>SOLUTION: When the sheet P having larger size than the sheet P stacked in the stack tray 18 is ejected and stacked or when the number of ejected sheets is small even though the size of the sheets is different, it is not decided as a mixed stacking state even though it is practically mixed stacking, and stacking target height is set to be equal to height obtained when the sheets having the same size are stacked. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
