PURPOSE:To easily recognize a pulling-back quantity when the pulling-back of a CF is carried out by continuing the action of a CFF completely regardless of a jam when the jam occurs and stopping the action when a copy region is completely set. CONSTITUTION:The CF (computer form) detecting sensor S1, and the detection states of various types of sensors such as a jam sensor are inputted into a CPU 21, and a mode setting signal, a printing start command signal, etc., are inputted into an operating part 22. When the jam is detected by the jam sensor, the state is displayed on the display panel of the operating part 22. When the jam of a copy paper occurs on a copying machine main body side and the CFF (computer form feeder) is operated, the CFF is operated till the next copy region is set on an original platen regardless of the jam of the copy paper, and is stopped after the copy region is set. The next copy region is completely set in such a manner,a nd then, the feeding of the CF is stopped. Thus, a region is easily classified and the pulling-back working of the original is easily carried out. |
