Abstract
A copy machine (10) of the type for producing enlargements or reductions of an original material includes mirrors (14) for reflecting an image of the original material to a lens (16) and from the lens (16) to an image fixing system (18), and a lens (16) for enlarging or reducing the image reflected thereto by the mirrors (14). The lens (16) is fixed relative to the machine (10). The image fixing system (18) fixes the reflected image on a substrate. The mirrors (38,40,44,46) are moveable for enlarging or reducing the image reflected to and from the lens (16). The machine (10) includes a control system (20) for controlling the movement of the mirrors (38,40,44,46) and simultaneously reducing or enlarging and focusing the image reflected to the image fixing system (18).
