Abstract

Appareil de validation de billets de banque comprenant un système optique, un système électrique, un terminal d’application et un dispositif d’alimentation, pouvant créer des informations image du billet de banque détecté exposé au signal, qui se transforment deux fois avec des énergies variées. Le signal optique est transformé en un signal électrique par le capteur d’image dans le récepteur d’image et le signal électrique est re-transformé en signal optique par l’affichage électrique. Le premier degré est que l’amplification optique est obtenue par le système optique. Le deuxième degré est une amplification électrique obtenue par le processeur vidéo et une autre amplification électrique obtenue par l’affichage électrique du récepteur d’image, respectivement. Le micrographe du point d’échantillonnage de billet de banque détecté peut apparaître simultanément sur les deux affichages de la présente invention et il peut en même temps être enregistré par l’enregistreur de surveillance. Ainsi, l’appareil de validation de billets de banque peut détecter la validité d’un billet de banque.
