Abstract

DISPOSITIVO LECTOR OPTICO PARA CODIGOS DE FRANJAS PORTADOS POR ENVASES EN MOVIMIENTO. CONPRENDE UNA CAMARA DE EXPLOTACION (18) QUE DETECTA, MEDIANTE FOTODIODOS, LAS FRANJAS BLANCAS Y NEGRAS DE UNA ETIQUETA (16) Y LAS CONVIERTE EN UNA SEÑAL ANALOGICA (24). DICHA SEÑAL ES DIGITALIZADA MEDIANTE EL DETECTOR DE UMBRAL (36). LA TENSION DE UMBRAL, OBTENIDA EN EL DETECTOR (36), Y LA SEÑAL (24) SON APLICADAS A UN COMPARADOR (42). LA SALIDA DEL CITADO COMPARADOR, COMPUESTA POR UN TREN DE CEROS Y UNOS CORRESPONDIENTES A FRANJAS BLANCAS Y NEGRAS RESPECTIVAMENTE, ES APLICADA AL FILTRO (46), QUE REQUIERE QUE AL MENOS DOS FOTODIODOS ESTEN EN EL MISMO ESTADO PARA RECONOCERLO.
