Abstract

PURPOSE:To make it possible to obtain a copying picture from the transparent original besides the ordinary original simply, by providing the second exposure optical system besides the first exposure optical system, which irradiates the ordinary picture original, to make it possible to form the copying picture even from the transparent original. CONSTITUTION:In overall exposure optical system B to focus the transparent original onto photoreceptor 3, heat prevention glass 33 is provided between light source lamp (a) and condenser lens 10 for preventing heat from lamp 9 from being transferred to transparent original 8, and mirror 34 is provided which constitutes a part of the monitor optical system D which monitors the copying picture of original 8 before copying. Heat prevention glass 33 is provided with a correction mask to correct illumination unevenness of the transparent original. Further, monitor optical system D is constituted the first mirror 34, which is arranged on the light path of original 8, and the second and the third mirrors 37 and 38 which receive the reflection light from the first mirror to lead it to monitor window 36.
