Abstract
PURPOSE:To detect a defective processing device in a simple and quick way and then to perform the repair and inspection with high efficiency, by using a detector which detects the present process execution value in the form of an analog value and an analog indicator which receives the output from each detector via a selection switch. CONSTITUTION:The detectors CVT1-CVT5 detect the execution value of each of a series processes for charging, exposure, development, transcription and fixing respectively. At the same time, the outputs given from those detectors are switched to 121-125 via a selection switch 12 and displayed at an analog indicator 13. When the nondefective or defective state is detected for each of the above-mentioned process devices, the catch 128 of the selection switch 12 is switched successively. Then whether are present process execution value indicated by the indicator 13 with each switching is within a proper control range is confirmed. In such way, the simple and quick discrimination is possible.
