<p><P>PROBLEM TO BE SOLVED: To provide a method to accumulate sheets while making conflicting requirements of productivity and consistency compatible appropriately. <P>SOLUTION: A post-processing device 2 is disposed in the third conveyance path R3 on the upstream of the second paper discharge roller 26 and includes an overlapping part 40. The overlapping part 40 is configured to supply a plurality of sheets P to the second paper discharge roller 26 in the state that they are overlapped. A post-processing control part determines the necessity of performing an overlapping operation by the overlapping part 40 based on the weight of the sheets P introduced into the device. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
