Abstract
Abstract A display device according to the present invention is incorporated into a machine in order to display the operating condition of the machine. The machine has at least one movable part, such as a door, to be opened by an operator when the machine stops operating due to a malfunction. This display device schematically shows, by means of display elements, the positions of the movable parts before and after the operator moves them, and displays the elements in accordance with the condition of the machine. Upon the occurrence of a malfunction in the machine, the display elements on the schematic display corresponding to the faulty machine part can be displayed so as to be understood by the operator.

Claim 1
Independent Claim
109 words
For use with a machine having a plurality of component parts, at least one of which is movable to permit access to be made to other component parts of the machine, a display device comprising a plurality of display segments formed to schematically illustrate at least some of said component parts, including said movable part, and display control means coupled to said display segments for activating selected ones of said display segments in response to the occurrence of a malfunction characterised in that said display control means activates said display segment(s) corresponding to the or each movable part which must be moved to enable the malfunction to be corrected.
Claim 2
Dependent Claim
109 words
For use with a machine having a plurality of component parts, at least one of which is movable to permit access to be made to other component parts of the machine, a display device comprising a plurality of display segments formed to schematically illustrate at least some of said component parts, including said movable part, and display control means coupled to said display segments for activating selected ones of said display segments in response to the occurrence of a malfunction characterised in that said display control means activates said display segment(s) corresponding to the or each movable part which must be moved to enable the malfunction to be corrected.
Claim 3
Dependent Claim
23 words
A display device as claimed in claim 1, characterised in that said display segments schematically illustrate said movable part in its moved position.
Claim 4
Dependent Claim
47 words
A display device as claimed in claim 1 or 2, wherein the machine is an electrophotographic copying machine and characterised in that said movable part which must be moved is an upper cover which, when moved, separates said machine into two parts along a paper transportation path.
Claim 5
Dependent Claim
39 words
