An apparatus comprising a projection lens, a first reflector and a second reflector wherein a frame of desired information of a microfilm or microfiche placed on a predetermined projection position in the apparatus, has its picture projected through the projection lens and first and second reflectors on a screen of the light transmission type to form an enlarged image of the information on it which can be observed from outside the apparatus. When it is desired to make a duplicate of the information on an enlarged scale, the second reflector is withdrawn from the path of light projection and an optical image of the information is transmitted through the projection lens and first reflector to the surface of an electrophotographic photosensitive sheet electrically charged uniformly beforehand to form an electrostatic latent image which is then developed into a visible image to provide a duplicate of the information. |
