Title: Double-sided original high speed copying device
Inventor: HOSHI AKIMITSU
IPC: G03G21/00
Filed: 1989-05-25
Abstract: PURPOSE:To carry out paper ejecting and reversing of an original processing device simultaneously and to eliminate waste of time when an original is reversed by providing a reversing part which selectively reverses a copying paper to a paper ejecting part in the down stream of a fixing device. CONSTITUTION:When there is no reversing part for ejected paper in a main body, it is always necessary to copy an even numbered page first and then an odd numbered page next. For that reason, from the view of a circulatory original feeding device 1, the reversing should be carried out to have the even numbered page come to a platen side, not at the paper ejecting time but at the time of original setting. Therefore, since there is little chance to carry out reversing and original ejecting simultaneously, the copying speed is not improved. So, by providing the ejected paper reversing part in the main body 2 as shown in the diagram to reverse paper at the time of paper ejection then paper ejecting and reversing can be simultaneously performed to greatly speed up the process.
