Abstract
A copying apparatus includes an automatic document feeding apparatus (hereinafter referred to or RADF) for automatically feeding a document onto the platen glass table for copying and for re-feeding the document onto the glass table after the document is reversed. The RADF has an upper roller with a large radius and a lower roller with a small radius. First, second, and third gates are located along the periphery of the upper roller. When feeding the document, the first and second gates define a document path from a document feed tray to the platen glass table. When reversing the document, the first, second, and third gates define a document path for reversing the document and re-feeding the reversed document onto the platen glass table. When ejecting the document, the second and third gates define a document path from the platen glass table onto a surface of the RADF.
