Abstract

PURPOSE:To make it unnecessary to provide a special front arranging mechanism to copy information on the surface and the reverse face of a copy paper, by not ejecting the copy paper, where the copy on the surface is completed, to the outside of a machine but leading it a transfer device again for the copy on the reverse face. CONSTITUTION:In a copying machine, a copy paper which passes through a fixer 20 at a surface copy time and is carried by an ejecting roller 22 and advances while having extra charge discharged by a discharger 23 has the trailing edge detected by a photodetector 24 and is led to a passage 25 for the reverse face copy by inversion of the ejecting roller 22. A guide plate 26 is displaced to a position for guiding the copy paper to the passage 25 simultaneously with inversion of the ejecting roller 22, and the copy paper is led to a paper supplying device for reverse face, and many copies are piled up there. By this constitution, the copy paper is carried without providing a special front arranging mechanism, and information is copied on the surface and the reverse face with a simple constitution.
