Abstract

L'invention porte sur un agrandisseur double face (100), qui comprend un mécanisme d'entrée de papier (110), une station d'exposition (120), un dispositif d'exposition (130), un mécanisme de transfert de papier (140), un mécanisme d'inversion (150) et un mécanisme de sélection (160). Le mécanisme d'entrée de papier (110) fait entrer le papier en vue d'une exposition. La station d'exposition (120) est positionnée derrière le mécanisme d'entrée de papier (110) pour supporter le papier. Le mécanisme de transfert de papier (140) a une courroie de transfert (141) qui s'étend autour de la station d'exposition (120) pour transférer le papier vers la station d'exposition (120). Le dispositif d'exposition (130) émet de la lumière pour exposer le côté du papier qui fait face à la lumière sur la station d'exposition (120). Le mécanisme d'inversion (150) inverse le papier entré et le transfère vers la station d'exposition (120) pour amener un autre côté du papier qui n'a pas été exposé à faire face à la lumière. Le mécanisme de sélection (160) est disposé entre la station d'exposition (120) et le mécanisme d'inversion (150) pour déterminer si le papier est transféré dans le mécanisme d'inversion (150) ou directement délivré en sortie. L'agrandisseur double face a uniquement besoin d'un dispositif d'exposition et peut utiliser l'agrandisseur de face unique classique de manière efficace.
