Abstract
L'invention concerne un processeur de présence de caractères destiné à un dispositif de reconnaissance de caractères. Il reçoit d'une matrice d'analyse des signaux numériques destinés à localiser un intervalle entre des segments de caractère. Par comparaison avec une liste mémorisée dans une mémoire permanente de caractères spéciaux et de caractères comportant fréquemment des jambages affaiblis, il émet s'il y a lieu un signal de blocage pour interdire qu'un caractère séparé par un intervalle soit considéré comme deux caractères séparés. L'invention s'applique aux dispositifs optiques et magnétiques de reconnaissance des caractères.
