Abstract

Mécanisme de commande d'un système optique à balayage à réduction variable de manière continue. Un premier document 20 a été représenté positionné sur un bord de référence et centré par rapport à ce bord. D'une manière similaire, un second document rectangulaire 21, de plus grand format que le document 20, a été représenté positionne sur le même bord de référence et centré par rapport à ce bord. L'objectif est déplacé dans deux directions dans un appareil à réduction à cadrage par rapport à un bord de référence, à savoir le long de l'axe de grandissement M et le long d'un axe perpendiculaire X.
