PURPOSE:To stack in page order even when plural sets of documents of plural pages are formed by repeatedly recording, on the front surfaces of papers, plural sets of odd pages in ascending order or plural sets of even pages in descending order, and then repeatedly recording, on the back surfaces of papers, unselected ones out of plural sets of odd pages in ascending order and plural sets of even pages in descending order. CONSTITUTION:Either plural sets of odd pages in ascending order or plural sets of even pages in descending order are repeatedly copied on the front surfaces of the papers 28. After that the papers 28 are stacked on an intermediate tray 71 in order from the top to down, and then the stacked papers 28 are sent out in order from the top; subsequently, out of plural sets of odd pages in ascending order and plural sets of even pages in descending order, unselected ones are repeatedly copied on the back surfaces of the papers 28. Afterwards they are ejected with the copied side facing down, and thus, plural sets of documents of plural pages are formed. |
