A printer ribbon cartridge (10) containing an internal re-inking mechanism (12) for re-inking the ribbon (14) housed in the cartridge is provided. The internal re-inking mechanism (12) comprises a drive assembly (30), pump (24), an eccentric (26), an ink reservoir (22), an ink feeding tube (34), a re- inking ring (36) and a transfer roller (38). As the ribbon (14) is threaded and propelled through the drive assembly (30), the drive assembly drives the pump (24) via the eccentric (26). The pump (24) pumps ink from the ink reservoir (22) to the re-inking ring (36) through the ink feeding tube (34). The ink is transferred from the re-inking ring (36) to the ribbon (14) via the transfer roller (38).

Cartouche d'imprimante à ruban (10) comprenant un mécanisme interne de réencrage (12) pour le réencrage du ruban (14) logé dans la cartouche. Ce mécanisme de réencrage interne (12) comporte un dispositif d'entraînement (30), une pompe (24), un excentrique (26), un réservoir d'encre (22), une conduite d'amenée d'encre (34), un anneau de réencrage (30) et un rouleau de transfert (38). Au fur et à mesure que le ruban (14) est embobiné et propulsé par le dispositif d'entraînement (30), ce dernier dispositif entraîne la pompe (24) par l'intermédiaire de l'excentrique (26). La pompe (24) envoie de l'encre à partir du réservoir d'encre (22) à l'anneau de réencrage (36) en passant par la conduite d'amenée d'encre (34). L'encre est transférée de l'anneau de réencrage (36) au ruban (14) par l'intermédiaire du rouleau de transfert (38).
