Abstract
An electrophotographic copying machine includes a control circuit, a combined display responsive to the control circuit for showing the number of one or more copied papers, and the position of any paper jam or the operation condition. The combined display utilizes figure segments illuminated to form any figure, silhouette segments of the figure segments illuminated to provide a silhouette of the copying machine, and position marks illuminated to indicate the position of trouble in the machine and its operation conditions.
