Definitions

  • the invention relates to a ribbon cassette, and, in particular, to a self-regulating re-inking mechanism included therein.
  • Fig. 2 is a top plan view of the body of a ribbon cassette having the cover removed to show the interior structure
  • the roller 82 is preferably the drive roller and is con ⁇ nected to a drive member (not shown) while the idler roller 80 is maintained in a biased position against • such roller 82 by means of a spring 88 wrapped around a stud or pin 90 and having one end thereof engageable against one end of a support arm 92 pivoted on a spin ⁇ dle or a shaft 94.

Abstract

Une cassette à ruban comprend une enceinte (50), un ruban sans fin (84) contenu dans l'enceinte (50), et des organes d'entraînement (81, 82) pour l'avance du ruban (84) à l'intérieur et à l'extérieur de l'enceinte (50) pour une utilisation dans des opérations d'impression. L'enceinte contient un mécanisme de réencrage du ruban comprenant un rouleau poreux d'alimentation en encre (100) supporté de manière rotative à un emplacement fixe, et un rouleau de transfert d'encre (110) monté de manière pivotante de manière à rentrer en contact rotatif avec le rouleau d'alimentation en encre (100) pour le transfert d'encre du rouleau au ruban, le ruban (84) appliquant la force nécessaire à solliciter le rouleau de transfert d'encre (110) en contact avec le rouleau d'alimentation en encre (100). Le mécanisme de réencrage est auto-réglable puisqu'une augmentation de la tension du ruban (84) indiquant son appauvrissement en encre provoque un accroissement de la pression sur le rouleau d'alimentation en encre (100) pour accroître le transfert d'encre au ruban (84), et une diminution dans le ruban (84) indiquant une condition de saturation d'encre dans le ruban (84) provoque une diminution de la pression sur le rouleau d'alimentation en encre (100) pour limiter le transfert d'encre au ruban (84).
