Abstract

PURPOSE:To let the conditions of inputting and outputting in the respective inspection sections of the copying machine by readily displayed and save labor and time by so constituting the apparatus that the write information of the addresses selected by selectors may be discretely checked by a display device. CONSTITUTION:When the arbitrary addresses of the input buffer area or output buffer area of a RAM are selected by select switches SW1, SW2 and a select switch SW3 is selected to the operation side of a display device, the selected code signals is input to an input port and a CPU writes the inputs of the code signals in the address of the RAM corresponding to the code signals. For example, if the content of the address is 0, a lighting signal is output to the circuit of an LED1 and if the content of the address is 1, a lighting signal is output to the circuit of an LED2 to let these be lighted. Hence, whether the driving signal of each copying operation member is output may be readily checked by the LED1, LED2.
