Abstract

L'objet de la présente invention est d'améliorer la visibilité d'un dispositif d'affichage d'opération à un faible coût. Un panneau d'affichage d'opération comprend une unité d'exploitation servant à faire fonctionner un équipement et une unité d'affichage servant à afficher des informations concernant l'équipement. Une plaque de guidage de lumière est formée d'un matériau laissant passer la lumière et est stratifiée sur le panneau d'affichage d'opération. Une source de lumière émet de la lumière depuis la face d'extrémité de la plaque de guidage de lumière vers l'intérieur de la plaque de guidage de lumière. Une unité de commande commande la source de lumière. La plaque de guidage de lumière comprend une pluralité de prismes. La pluralité de prismes présente un motif donné sur la surface de la plaque de guidage de lumière par réflexion de la lumière provenant de la source de lumière. L'unité de commande commande la source de lumière pour modifier la présentation du motif donné.
