ABSTRACT:
A symmetrical printer ribbon cartridge which is refillable. An internal, continuous drive belt (15) provides tension to push studs (33, 35) of the supply spool (23) and of a take-up spool (29) to the ends of notches (31, 32) in cartridge wall 1. When the original supply spool is emptied, a new spool need only be moved into place and the free end of the ribbon pulled from the new spool, directed through the ribbon path in the cartridge, and attached to the remaining spool.
