PCT No. PCT/JP80/00304 Sec. 371 Date Jul. 31, 1981 Sec. 102(e) Date Jul. 31, 1981 PCT Filed Dec. 11, 1980 PCT Pub. No. WO81/01685 PCT Pub. Date Jun. 25, 1981.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 relative roughness of the surface (12) of the ink ribbon which is subjected to collision with the type compared to the relative smoothness of the other surface (13), the contact point (17) of the feed rollers is located in a biased position with respect to the center (18) of the ribbon case so that the contact point is closer to the side wall (6b) of the ribbon case that faces the smooth surface of the ink ribbon than to the side wall (6a) of the ribbon case that faces the rough surface of the ink ribbon, 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 that faces the smooth side of the ink ribbon.
