複写機。[Scope of Claim for Utility Model Registration] An exposure light source that provides light for exposure, an original moving mechanism that moves an original at a set speed relative to the exposure light source, and an original that is moved by the original moving mechanism according to the copying magnification of the original image. A copying machine is provided with a speed control means for changing the moving speed of the exposure light source, and a control means for moving the position of the exposure light source according to the copying magnification and controlling the travel time from the leading edge of the document to the exposure start point to be constant. A copying machine characterized by:
