PURPOSE:To easily execute variable magnification, by providing a pair of connecting parts positioned at both sides of a moving pulley, on a setting member, fixing each of both ends of a rope to each of one pair of connecting part, and providing a setting cam and the setting member on a conventional unmagnification copying machine. CONSTITUTION:On a pair of suspension rods 20, the first reflector assembly 3 is placed so as to be in parallel with an original loaded on a static transparent plate 2 and also so as to be movable horizontally. Also, on a pair of suspension rods 22, the second reflector assembly 32 is installed so as to be in parallel with the original and so as to be movable horizontally in parallel with the moving direction of the first moving reflector 4. The first reflector assembly 30 is provided by an inclination of 45 deg. against a light source 34 and the original, the second reflector assembly 32 is provided by an inclination of 45 deg. against the original, and the second moving reflector 6 for reflecting a reflected light from the first moving reflector 4 in the vertical direction, and the third moving reflector 8 provided at a right angle with this reflector 6 are equipped. |
