ABSTRACT:
The feeding of typewriter ribbons is improved by utilizing a cartridge carried driving element engaging the periphery of a translatable take-up spool where the driving element is driven by an interface connection with a driving member connected either directly or through a gear reduction train to a stepper motor. The simplified ribbon feed mechanism provides control over the increment of feed electronically as well as each ribbon cartridge carrying the appropriate gear reductions, if necessary, for different types of ribbons.
