INK RIBBON FOLDING MECHANISM FOR A PRINTING APPARATUS ABSTRACT OF THE DISCLOSURE An ink ribbon folding mechanism for a printing apparatus is adapted for folding an endless ribbon (3) in a ribbon case (6) by means of a pair of feed rollers (4, 4': 4A, 4A'). For achieving a smooth folding of the ink ribbon, in spite of the roughness of a surface (12) of the ink ribbon which is subjected to the type, a contact point (17) of the feed rollers is located in a biased position with respect to the center (18) of the ribbon case on the side of a smooth surface (13) of the ink ribbon which is not subjected to the type, whereby, even though when being folded on the side of the smooth surface, the ink ribbon can reach a side wall (6b) of the ribbon case.
