ABSTRACT:
A magnification enlargement type copying machine in which the image of a picture on a film is projected onto a screen or a photo-sensitive drum by an image enlarging lens to be observed and copied. The size of a picture on a film to be copied and a size of a copying sheet on which an enlarged image of said picture are inputted to the system. An enlargement magnification is then observed and following correct placement on the proposed sheet, the film is moved from the observation position to a scanning start position according to the size of the picture on the film. The film is then scanned at a speed corresponding to a set magnification thereby to form the image of the picture on a photosensitive drum. An arithmetic control unit is used for calculating a distance between an observation position and a scanning start position from a size of a picture on the film and calculates the film scanning speed from a set magnification.
