Abstract

Machine de production de copies comportant une répétition de la prise de feuille. Elle comporte un détecteur, afin de détecter qu'une feuille qui vient d'être prise est prête à entrer au poste de transfert. Un dispositif de synchronisation associé de façon fonctionnelle avec le poste de transfert indique le fonctionnement synchrone, ainsi que le moment où le poste de transfert doit recevoir une feuille. Un dispositif de coïncidence réagit conjointement au détecteur et au dispositif de synchronisation pour indiquer que la prise de feuille est réussie ou non. Une commande réagit à une indication de défaillance de prise de feuille pour inhiber le transfert d'image pendant un cycle machine dans le poste de transfert d'image. Un compteur indique un certain nombre de défaillances de prise de feuille successives. D'autres commandes réagissent aux indications du compteur pour arrêter la machine de production de copies après un nombre prédéterminé de défaillances de prise de feuille.
