Abstract

PURPOSE: To preform organic control and management and perform high speed multifunction processing rapidly and surely by providing plural microprocessors for various controls and checks and providing local memories respectively thereto and further providing a common memory.
CONSTITUTION: Various functions and chesck functions of a copying machine 1, e.g., sequence control of copying processes, various safety and abnormality checks, as well as automatic control by sensors such as of temperatures, concentrations, illumination, photoreceptor potentials, etc. are divided to plural blocks, e.g., 3 blocks. The tasks of these blocks are handled with microprocessors (CPU) 2, 3, 4. And local memories 5, 6, 7 having been stored with processing programs respectively therein are provided thereto. For these, a common memory 8 is provided and the organic control and management among the CPUs 2, 3, 4 by the control programs and common program of the common memory are performed
