Abstract

PURPOSE:To prevent malufunctions of the unit and achieve higher reliability and maintenance characteristic by time serially processing the operations of the respective parts of the unit through the use of a microcomputer in a copying machine or the like. CONSTITUTION:The signals corresponding to the operations of respective magnetism detecting elements, microswitches, etc. of the copying apparatus are supplied from a matrix circuit to the inputs I1, I2, I4, I8 of a microcomputer and the signals for driving a pulse transformer, miniature lamps, solenoids, electromagnetic clutches, etc. are obtainable in its outputs O1 thru O15. In this time serial processing, a part of the output signals is supplied as a probe signal to the matrix circuit in order to read one signal from the input signal group. The specified output signals from the computer are supplied to an output control circuit, whereby specified logic processing is accomplished, after which driving of the specified load is accomplished.
