SCANNING METHOD AND APPARATUS APPLICABLE TO VARIABLE MAGNIFICATION COPYING MACHINES ABSTRACT In a variable magnification copying machines capable of performing slit exposure of the image of original document to the surface of a photoconductor with a desired magnification by moving a contact glass on which the original document is placed or an optical system in synchronization with the photoconductor which is moved at a predetermined con- stant speed, a scanning method and apparatus in which the moving speed of the optical system or of the contact glass at the exposure step and the moving speed of the same at the re- turning step to the original position thereof are made vari- able depending upon a selected magnification of the copy of the original document, and the moving speed of the optical system or of the contact glass is set in such a manner that the sum of the time required for the optical system or the con tact glass to move for exposure scanning and the time required for the optical system or the contact glass to return to the home position thereof is constant regardless of the selected magnification of the copy of the original document.
