Abstract
A ribbon cartridge for use in impact printers, typewriters or the like in which a supply spool and a take-up spool are enclosed in a housing with the center of each spool being supported for rotation and for floating movement along a guide path. A fixed center drive capstan imparts surface movement to the take-up spool which in turn imparts surface movement to the supply spool. A spring urges the surfaces of the spools together and the take-up spool against the drive capstan to effect the serial drive train.
