Abstract
PURPOSE: To perform various kinds of fault diagnosis and controlling with a simple constitution by counting the reference clocks according to the operation signals of the copying machine.
CONSTITUTION: The machine signal A from the copying machine unit 6 is supplied to a CPU10 through an input signal control part 9 to start the counter in the CPU10 so that counting of reference clocks 5 is started. When the machine normally operates after this and the machine signal B is supplied, the counting is stopped and the counter is reset, at the same instant of which the signal X or Y for driving or stopping driving means such as motor is supplied to the copying machine 6 through an output control part 11. Hence, if there are no faults in the sensor and machine, the contents of the counter are reset when the signal B arrives while the counter is counting the reference clocks 5 for the specified value N1 after the arrival of the signal A and when no signal B is generated, the counter decides it a fault upon reaching of the specified value N2, then a fault state display device 7 is operated and the driving of the machine is released so that the machine is retreated from the fault state.
