Abstract
A copying apparatus equipped with an original document circulation feeding arrangement for feeding to an original document platform. A plurality of original document sheets are stacked on an original document tray and sequentially feed from the original document sheet located at the lowermost position of the stack. The original document sheets are discharged from said original document platform, onto the uppermost position of the original document sheets stacked on said original document tray. The original document circulation feeding arrangement includes an original document size detecting member for detecting the sheet size of the original document during feeding thereof from said original document tray. An original document size memory member subjects the original document sheets stacked on the original document tray to one circulation before starting of copying function. During the time of circulation, the apparatus sequentially stores all the sheet sizes detected by the original document size detecting member in a memory of a control section.
