PURPOSE:To form a copied picture obtained by moving a part of an original image up to a required position by delaying or advancing an irradiating end part and a photodetecting end part each other by a phase controlling means controlling the phase of the scanning starting position of a photosensitive body. CONSTITUTION:In case of normal copying, a fluorescent lamp 20 is turned on when the right end surface 26 of the original surface 18 is located on an exposure position opposed to an optical fiber 22, and driving motors 2, 4 drive the original board 30 and the photosensitive body 10 at an equal speed while synchronizing the board 30 and the photosensitive body 10. Consequently, a copied image corresponding to the image of the original surface in the ratio of 1 to 1 is obtained. In order to move a picture 40 on the final position of the original surface 18 to a position close to the center of the copying surface, the fluorescent lamp 20 is turned on, the original is irradiated from the right end part 26 and only a driving motor 2 is driven by a phase controlling circuit 5 to start the scanning of the original surface. After scanning the original surface by a distance l1, a driving motor 4 is driven. In order to move a picture 36 on the starting position of the original surface 18 to a position close to the center of the copying surface, the driving motor 4 drives only the photosensitive body 10 at first, and after moving the photosensitive body 10 by a distance l2, the driving motor 2 is driven. |
