Abstract
A display for a copying apparatus includes a display element for indicating the operating conditions of the copying apparatus. The display has a number of detectors for detecting each of a group of operating conditions and an energizer for energizing the display element in response to the outputs from the detectors. The display element operates with a predetermined on-period and a predetermined off-period for each corresponding detector. The display is capable of displaying a group of operating conditions by a single display element through a group of display conditions such as being on, being off and blinking.
