PURPOSE:To perform side erasing and destaticization of a photosensitive body with one lamp to simplify the constitution of a copying device by dividing a reflecting plate facing the exposure lamp by transfer paper sizes and providing divided plates freely movably independently of one another and displacing them with a reflecting plate driving device. CONSTITUTION:An exposure lamp 2 is provided under an original surface 1 on a copying device, and a reflecting plate 3 is arranged to face the lamp 2. This reflecting plate 3 is freely turned and displaced around a fulcrum 4 in the lower end side, and this reflecting plate 3 is divided into reflecting plates 3a-3d by transfer paper sizes. This reflecting plate 3 is displaced between stoppers 5a and 5b by the reflecting plate driving device consisting or a CPU 8 and solenoids 7a-7d. Individual reflecting plates 3a-3d divided by transfer paper sizes are displaced by the reflecting plate driving device, and one lamp 2 is used to perform erasing of front and rear ends and sides of an image and exposure of the photosensitive body, thus simplifying the constitution of the copying machine. |
