Abstract
A copying machine has exposure lamps for scanning an original, line sensors for recognizing an original pattern, an imaging lens, a blank exposure lamp to eliminate a black frame and a central black stripe of a reproduced image if the original is thick (i.e., book), and a controller with an MCU. The set condition and shape of the original are recognized and displayed to allow optimal image formation.
