Abstract
(EN)
The invention relates to a method and a device for validating and characterizing coins, comprising partial illumination of the edge of the coin (1) using a collimated light beam (6) with a rectangular section that hits the edge of the coin as a string running parallel to the axis of said coin and having a width that is the same or smaller than the thickness of the alterations to be detected. A sensor (9) to analyze the reflected light is disposed in such a way that only the diffused reflection (11) generated by the relief or alterations in the surface of the edge of the coin reaches said sensor and not the specular reflection (12) caused by the smooth areas of said edge.
(ES)
Método y aparato para la validación y caracterización de monedas, que comprende la iluminación parcial del canto de la moneda (1) mediante un haz de luz colimada (6) de sección rectangular, que alcanza el canto de la moneda según una franja paralela al eje de dicha moneda, de anchura igual o inferior al grueso de las alteraciones que se pretenden detectar. Un sensor (9) para analizar la luz reflejada se dispone de modo que sea alcanzado solo por la reflexión difusa (11) que origina el relieve o alteraciones de la superficie del canto de la moneda, pero no por la reflexión especular (12) producida por las zonas lisas de dicho canto.
(FR)
Le procédé selon l'invention consiste à éclairer partiellement la tranche de la pièce de monnaie (1) à l'aide d'un faisceau lumineux collimaté (6) de section rectangulaire. Ce faisceau atteint la tranche de la pièce en formant une frange parallèle à l'axe de ladite pièce, et dont la largeur est inférieure ou égale à l'épaisseur des altérations devant être détectées. Un capteur (9) est prévu pour détecter la lumière reflétée de telle sorte qu'il ne capte que la lumière diffusée (11) émise par le relief ou les altérations de la surface de la tranche de la pièce, mais ne capte pas la réflexion spéculaire (12) générée par les zones lisses de cette tranche.
