Abstract
A ribbon take-up drive mechanism for a universal ribbon cartridge. The cartridge is adapted to engage the ribbon drive shafts of printers of two different designs. The drive shaft positions are different, and the direction of drive shaft rotation is opposite for the two designs. The take-up mechanism is designed such that the ribbon is pinched between the teeth of a direct drive gear and a biased idler gear. The printer of one design drives the ribbon through the direct drive gear. The printer of the second design drives the ribbon through an alternate drive gear, an idler gear and the biased idler gear. In either case, the ribbon is advanced in the same direction.
