Abstract

L'invention concerne l'impression de caractères par des moyens magnétiques. L'invention consiste en une tête magnétique 12 destinée à enregistrer sur une bande magnétique 18 des images magnétiques correspondant aux caractères que l'on désire imprimer sur une feuille de papier 16. Les images magnétiques sont transformées en images optiques puis transférées et fixées sur la feuille 16. Application aux imprimantes par ligne.
