Abstract: <P>PROBLEM TO BE SOLVED: To discharge a paper sheet by determining a state where discharged paper sheets do not scatter and automatically releasing a paper discharge suppressing state.  <P>SOLUTION: When a paper discharge suppressing button is pushed while a job for discharging to a paper discharge tray is being executed, pushing information of the paper discharge suppressing button is transmitted to a controller controlling part from a finisher, and execution of the job is interrupted by the controller. When the paper sheet is eliminated from the paper discharge tray after the job stops, a level difference is generated between a paper discharge port and a top surface position of the paper sheet of the paper discharge tray. Therefore, the paper discharge tray starts rising movement in order to make up for the difference. At that time, paper discharge tray position information obtained from a paper discharge tray position detecting sensor is transmitted to the controller controlling part. The controller controlling part checks a difference between a position of the paper discharge tray and a position of the paper discharge port, and when the difference is not more than a predetermined value H, the execution of the interrupted job is restarted.  <P>COPYRIGHT: (C)2004,JPO
