ABSTRACT:
The present invention provides a sheet process device capable of performing a sheaf discharge operation to discharge sheaves of sheets stacked on a process tray to a stack tray, without discharging a next sheet to the process tray during the sheaf discharge operation and stopping an operation on a body side of an image formation apparatus. In the sheet process device, for example, in a case where an original consisting of six sheets of paper is carried, the first to third sheets are stacked on the process tray as they are without any designation, and the following fourth sheet is designated as a sheaf discharge sheet since it is the sheet two before the final sheet of the sheaf, whereby the sheaf discharge of the first to fourth sheets is performed. The fifth sheet after the sheaf discharge is designated as a wind sheet since a value of a wind counter has been set to be “2”. Then, when the fifth sheet is stacked on the process tray together with the sixth sheet designated as the final sheet of the sheaf, the sheaf discharge is performed.
