Abstract

L'APPAREIL FOURNISSANT DES IMPULSIONS COMMANDEES PAR LA ROTATION D'UN ARBRE 40 COMPREND UN DISQUE OPTIQUE INTERNE 56 PORTE PAR UN MOYEU 44 AVEC UNE PORTEE CHANFREINEE 68 COOPERANT AVEC UNE SURFACE COMPLEMENTAIRE 66 DU BOITIER 22, ET DES MOYENS DE RAPPEL 72 SOLLICITANT L'ENSEMBLE MOYEU 44 VERS CETTE PORTEE DE FACON A COMPENSER L'USURE MECANIQUE ET MINIMISER LES MOUVEMENTS ERRATIQUES DU DISQUE OPTIQUE 56. UNE DIODE ELECTROLUMINESCENTE 98 ET UN PHOTOTRANSISTOR 102 PRODUISENT DES SIGNAUX ELECTRIQUES EN REPONSE AU BLOCAGE ET LA TRANSMISSION DE LA LUMIERE PAR DES SEGMENTS OPAQUES D'ORIENTATION RADIALE DU DISQUE TOURNANT. UNE SECONDE COMBINAISON DE DIODE-PHOTOTRANSISTOR COOPERANT AVEC UN SECOND DISQUE STATIONNAIRE 112 PROCURE DES SIGNAUX CORRECTEURS.
