PURPOSE:To obtain easily a much advanced image processing function by connecting plural image processors which can be independently used, and starting copying operation from the image processors positioned on the down stream side by the signal from a means for detecting a recording medium. CONSTITUTION:When the connection of plural image processors (for example, copying devices) is perfect and a processing for detecting the connection ends, whether the copying is feasible or not is then discriminated by the presence or absence of, for example, a toner (developer) or recording paper. More specifically, whether the copying is feasible or not is discriminated in accordance with the detection signal C2 of various sensors Q3 in a sub-routine for diagnosig said copy and if the copying is infeasible, a copying prohibition signal C11 is transmitted in the same way as in the diagnosis for connection and thereafter the copying operation is stopped and what is a fault is displayed. The supervising is continued further and if the fault is eliminated and the copying is made feasible, the main routine is returned and the succeeding steps are started. The operation for copying is started if the copiable state is diagnosed in the above-mentioned way. |
