PROBLEM TO BE SOLVED: To maintain the temperature of a device body adequately, by exhausting the air flow by the heating of the device main body adequately, when a sheet processing device is connected to the picture image forming device main body. SOLUTION: When a sorter 1 as a sheet processing device is connected to a device main body 100, a conveying unit 22 to deliver the sheet is provided between a main body exhaust roller 106 and a carrying-in port 3 to carry in the sheet to the sorter. By providing an exhaust gas fan 25 to exhaust the heated air flow in the direction crossing to the conveying direction of the sheet, in this conveying unit 22, the temperature in the device main body is maintained constant, in the condition blocking the heat exhaust side in the device body. |
