Abstract

Système d'impression pour positionner un élément porte-caractères d'une imprimante à percussion en série. Le système comprend une roue d'impression en forme de marguerite avec des éléments de caractères portés aux extrémités à l'extérieur radialement de rayons formant un ensemble circulaire. La position de rotation de l'ensemble est détectée directement et optiquement par un ensemble de sources de lumière dirigée vers les rayons et, à travers les intervalles entre ceux-ci, vers un ensemble de détecteurs de lumière Différents caractères de l'élément d'impression qui forme le rotor d'un moteur pas-à-pas sont immobilisés à la position d'impression en réponse à une réaction fournie par les détecteurs de lumière. Application à l'impression automatique et à grande vitesse de caractères.
