PURPOSE:To obtain not only a copy of a usual original picture, but a copy image which is enlarged from a small-sized transmission original, by inserting a projecting optical system into a part of a mirror scanning optical system. CONSTITUTION:When a copying device is set to a projection mode, the first shutter 17 is closed, an optical path from an image exposing part 10 is cut off, and the device goes to a state that only image information from a projecting device 60 is made to reach an image forming position 37. When a housing 71 for covering a light source part of the projecting device 60 is raised, and a transmission original is positioned on a moving table 66, and the projecting device is operated by closing an opening part, a light beam from a light source 61 transmits through a heat ray absorbing filter 63, condensed by a condenser lens 64, receives a correction of a color filter 65 and goes into a diffusion box 70. Such a light beam goes to a uniform light beam which generates no uneven color nor uneven illumination in the box, and radiated to the transmission original on the moving table 66. The light beam which is transmitted through the transmission original goes to a luminous flux containing image information of the original, passes through a lens 67 and brought to an image inversion by a mirror 68, made incident on the surface of a sensitized material, brought to an image formation, and a latent image is formed.
