Abstract

EL DISPOSITIVO DE ANALISIS CONSTA DE UNOS ESPEJOS (11,12) PARA REFLEJAR LA RADIACION LUMINOSA PROVENIENTE DEL DOCUMENTO A ANALIZAR, UN OBJETIVO (21) PARA ENFOCAR DICHA RADIACION EN UNA BARRITA FOTOSENSIBLE (22), UN PRIMER SOPORTE (1) PARA SOSTENER LOS ESPEJOS (11,12), Y UN SEGUNDO SOPORTE (2) PARA SOSTENER EL OBJETIVO (21) Y LA BARRITA FOTOSENSIBLE (22). EL SEGUNDO SOPORTE (2) ESTA MONTADO MOVIL EN EL PRIMER SOPORTE (1) Y LA POSICION DE LA BARRITA FOTOSENSIBLE (22) PUEDE REGULARSE EN RELACION AL SEGUNDO SOPORTE (2). DICHO DISPOSITIVO SE UTILIZA EN APARATOS DE COPIADO, AL QUE CONFIERE UNA BUENA ADAPTABILIDAD.
