PURPOSE:To correct the forming position of an original image on paper automatically by selecting the setting reference of an original and moving a variable power lens block in accordance with the selected setting reference. CONSTITUTION:The original setting reference can be selected to the center part of a fixing scale 2x of an original board 2 or one side of the fixing scale 2x using a fixing scale 2y by setting reference setting keys 30a, 30b. When the key 30b is depressed for instance, the original setting reference is set up to the fixing scale 2y. Since paper feeding coincides with feeding reference Ps2, the center of the original does not coincide with the center of paper P even if the copying magnification is unmagnification, reduction or enlargement. Thereby, the variable power lens block 8 is moved in the optical axis direction and the direction rectangular to the optical axis direction in accordance with the copying magnification set up by the key 30b. Consequently, an image can be correctly formed on paper. |
