Abstract

L'invention concerne un télécopieur-récepteur. Dans la phase préliminaire de préparation, les circuits de réception et de traitement 5, reliés à l'unité centrale de commande 1, permettent à celle-ci de définir des signaux de secteur 1 mort extérieur SME. Un circuit de filtrage numérique 10 sélectionne l'un d'entre eux pour élaborer un signal RSME, qui est à son tour appliqué à un circuit 11. Celui-ci conserve la phase du signal SME, puis détecte l'écart temporel entre le signal RSME et le secteur mort local SM, puis agit sur l'entraînement du cylindre porte-papier pour annuler l'écart. Les deux fonctions sont articulées autour d'un même compteur-décompteur, en utilisant des fréquences d'horloge différentes. En correction, le moteur d'entraînement, peut être commuté immédiatement à deux vitesses qui s'écartent sensiblement d'un même pourcentage de sa vitesse normale. Application notamment en télécopie analogique.
