Abstract

1383101 Ink ribbon mechanisms NIXDORF COMPUTER AG 20 April 1972 [21 April 1971] 18337/72 Heading B6F Ink ribbon feed mechanism in a printer wherein ink ribbon spools are mounted on a print head carriage comprises wheels 48, 48a engaging a stationary element 50, the wheels 48, 48a acting through unidirectional clutches acting in opposite senses to rotate cog 46 or 46a respectively as the carriage is displaced, the cogs 46, 46a meshing with mutually meshing gears 29, 29a respectively, one of the gears 29, 28a meshing with a gear 28 or 28a coupled to the take-up spool, the gears 29, 29a being displaceable on a slide 31 to reverse ribbon feed direction. Feelers 40, 40a detect the diameter of the ribbon on the unwinding spool and reverse ribbon feed through a spring-biased arm 43 or 43a whereby a latch 35 or 35a is released to permit the gear train to displace the slide 31. The stationary element 50 may be a cable as shown, a rack, a plate or a rod. Ink ribbon guides (57, Fig. 4, not shown), displace the ribbon transversely for maximum wear through eccentrics 26, 26a on the gears 28, 28a. The eccentrics 26, 26a act on levers whose mean position may be electromagnetically adjusted for multicolour selection or to expose a line of print.
