  • Patent number: 4585338
    Abstract: In a photographic copying apparatus, in which the plane of the original and the plane of the copying material are positioned at the stable distance from each other, an objective has two optical elements which are adjustable relative to a reference position by means of the associated step motors in the axial direction so as to thereby adjust an image scale and a focus distance. A computer for controlling the step motors and two memory devices, connected to the computer, are provided in the apparatus. The data of the objective characteristics are stored in the first memory and specific apparatus data, as well as individual user's data, are programmed by a user and stored in the second memory. The computer controls the step motors in accordance with the capacities of the two memory devices.
