PURPOSE:To faciitate the maintenance and inspection of a copying machine by detecting currents, flowing through electronic parts constituting respective loads corresponding to respective functions of the copying machine, successively, by comparing the detected currents with a set current, and by displaying the results. CONSTITUTION:With a switch 9 closed, its switch output is inverted to a low level, and a load selecting device 8 generates pulses to control a comparing means 6 and a switch selecting means 4 with the successive pulses. Consequently, switches 1a-3a which correspond to loads 1-3 corresponding to respective functions of a copying machine are closed selectively, and currents flowing through electronic parts constituting the loads 1-3 are detected successively by a detecting means 5 and compared with a reference current to display the propriety of each function on a display device 4 through the means 6. This automatic operation facilitates the maintenance and inspection of the copying machine. |
