PURPOSE:To display the number of copied sheets and its charge on a position separated from a copying machine by arranging an oscillator for oscillating a count-up signal every counting-up time on each copied number counter part. CONSTITUTION:The oscillators 4-6 are arranged on the copied number counter parts of respective copying machines 1-3 and count-up signals are oscillated from the oscillators 4-6 every counting-up time. A copy center is provided with a receiver 8 and each count-up signal is received by the receiver 8. A control part 7 counts up the number of copied sheets and calculates its charge on the basis of the received signal. |
