Abstract

PURPOSE: To enable data exchange to be readily accomplished by providing the buffer region for performing data exchange between respective microprocessors with each other in the common memory which modules the programs for various controls and check functions and stores the same.
CONSTITUTION: This is the system of dispersing various controls and check functions or other of the copying machine to a plurality of microprocessors CPU 9W11 and processing the same, wherein all the programs thereof are moduled and stored in a common memory 8. The necessary programs are fetched from the common memory 8 according to the condition of the copying machine and are temporarily stored in reference memories 9aW11a. Of these necessary ones are transferred to process execution memories 9bW11b and are executed. The common memory 8 and the respective CPUs are disconnected and connected by pass-line changeover devices 15W17 and the buffer region for performing data exchange between the respective CPUs 9W11 with each other is provided in the common memory 8.
