PURPOSE:To take a variable power copying through inexpensive constitution, by projecting light upon a copy object through a standstill optical system for desired magnfication and picking up its image when the copy object is photographed with variable magnification. CONSTITUTION:A life-size copy is taken through the rod lens 70 of the 1st standstill optical system 62 for unmagnification copying, but the 2nd standstill optical system 64 is further provided. In this 2nd standstill optical system 64, reflected light from an original irradiated with light from an original illumination lamp 66 is projected on the 1st reflecting mirror 76 through an opening 88 formed in a housing 74, reflected successively by the 2nd reflecting mirror 78, the 3rd reflecting mirror 80, an in-mirror lens 82, the 4th reflecting mirror 84, and the 5th reflecting mirror 86, and then rojected on the photoreceptor 14 of a rotating drum 1 through an opening 90 formed in the housing 74, taking a variable power copying. |
