Abstract

In a ribbon cartridge 10, a ribbon 11 is drawn from a ribbon supply (not shown) and passes around a f1oating'~type idler ring 12; through the nip formed between ring 12 and a drive roller 13, around the drive roller and thence to ribbon take'~up spool 15. The drive roller 13 is caused to rotate clockwise, placing a first force on the ribbon. A ribbon tensioning means (not shown) located near the ribbon supply places a force on the ribbon in the opposite direction. As the ribbon advances, these forces create a tension in the ribbon which pulls ring 12 into a wedging position between support post 14 (about which the ring rotates) and the co~' operating portion of the drive roller 13. Ribbon 11 is pinched by serrations on both ring 12 and roller 13 in the nip area and is advanced toward take~~upspool 15. The take" up action is accomplished by an 0-ring (not shown) which transfers the rotational movement of drive roller 13 to take-up spool 15 thereby winding ribbon 11 onto spool 15.
