PURPOSE:To make the efficient processing possible by carrying an original document to another tray after the first reading and leading the original document from this tray to a reading part for following reading when the original document is read plural times. CONSTITUTION:A sheet in the bottom of a set of original documents placed on a tray 1 of an original document feeder A is separated and carried and goes to sheet paths (a) (b) (c) (d) and is inserted between the belt 25 of a circulating original document feeder B and a platen 26. Then, an optical system is operated to perform the exposure copy process for the original document. After exposure, the original document is carried to a tray 27 through sheet paths (h) (i) (j). After the processing of a prescribed number of original documents is terminated, original documents on the tray 27 are separated and carried in order from the bottom sheet, and each original document is sent to paths (j) (i) (h) (f) and is subjected to the exposure copy process. The original document is ejected onto a tray 24 through paths (f) (d) (b) (c) (e). Hereafter, originals documents on the tray 27 are processed similarly. |
