Abstract
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.

Claim 15
Dependent Claim
149 words
An electrophotographic copying machine, comprising: numerical display means for displaying a number of copies to be made, said numerical display means including at least two numerical figures of a block-eight formation, each of said numerical figures including seven display segments; alarm display means for indicating a position within the copying machine which requires maintenance, said alarm display means including at least some display segments of said numerical display means and a plurality of additional display segments superimposed on said numerical display means; means for selectively illuminating said numerical display means or said alarm means; and control means, responsive to the detection of said maintenance requirements, for selectively illuminating at least a portion of said numerical display means to form a silhouette of said copying machine, said plurality of additional display segments being illuminated in combination with the silhouette to indicate the position within the copying machine which requires maintenance.
Claim 16
Dependent Claim
149 words
An electrophotographic copying machine, comprising: numerical display means for displaying a number of copies to be made, said numerical display means including at least two numerical figures of a block-eight formation, each of said numerical figures including seven display segments; alarm display means for indicating a position within the copying machine which requires maintenance, said alarm display means including at least some display segments of said numerical display means and a plurality of additional display segments superimposed on said numerical display means; means for selectively illuminating said numerical display means or said alarm means; and control means, responsive to the detection of said maintenance requirements, for selectively illuminating at least a portion of said numerical display means to form a silhouette of said copying machine, said plurality of additional display segments being illuminated in combination with the silhouette to indicate the position within the copying machine which requires maintenance.
Claim 17
Dependent Claim
49 words
A copying machine according to claim 13, wherein the positions within the copying machine which require maintenance include positions related to a copy paper jam along the copy paper path, a low supply of developing agent, empty paper trays, a faulty photoreceptor, and damage to copy paper path sensors.
