PURPOSE:To make duplex and composite copying both performable, by installing such a device that selects from a face-down passage turning a copying surface of copying paper for a paper refeed cassette downward, to a face-up passage keeping it turned up intact, and vice versa. CONSTITUTION:A paper refeeder 30 is detachably installed in a paper discharge part 25 of a copying machine body 1, and here at, there is provided with a first selector claw 60 which guides the copying paper copied at the copying machine body 1 and to be discharged out of a pair of paper discharge rollers 21 to both sides of a paper discharge tray 45 and a paper refeed cassette 50. And, if a second selector claw 65 is set to a lower step position when being selected to the paper refeed cassette 50 side, the copying paper is guided to each of guide plates 75 and 78 by rollers 71-74, and its copying surface is turned down by a turnover roller 76, thus it is housed in the paper refeed cassette 50. On the other hand, when the selector claw 65 is selected to the lower step position, the paper is housed in leaving the copying surface turned up intact. Thus, the paper refeed cassette is doubly utilizable as a copying paper receiving device for both duplex and composite copying cases and, what is more, as a paper feeding device. |
