Abstract

PURPOSE:To make controlling more efficient and multifunctional by performing controlling by suitable combining static controlling and dynamic controlling according to the detection outputs of various sensors in a copying machine of a microcomputer control system. CONSTITUTION:When, for example, a thermosensor operates and its detecting contacts SW4, are closed, the power supply to a heater H, a main motor M, etc. is cut off by the command from a CPU. At the same time, the CPU makes the drive signal RD1 of the heater H zero to turn a control element 2 OFF and also causes a pilot lamp indicating the operation of the thermosensor to light. Further the CPU sends drive signals as to lower the temperature of the heater H and increase the speed of the main motor M by performing program changing through combination of the digit signals R1DR1-R1DG4 of that time to the control elements 2, 3, respectively, so that the operation of the copying machine is continued. The controlling is accomplished more efficiently and multifunctionally by combining the static controlling and dynamic controlling in this way.
