Abstract
La présente invention est relative à un appareil d'éclairage de documents. L'appareil comprend une première et une deuxième sources lumineuses fixes, un premier et un deuxième réflecteurs tournants servant à réflechir sur le document la lumière venant respectivement des première et deuxième sources, et un dispositif d'entraînement servant à faire tourner de façon couplée les premier et deuxième réflecteurs, de sorte que la lumière est réfléchie de ceux-ci sur le document avec une relation de superposition dans toutes les positions des premier et deuxième reflecteurs.
