Abstract

PURPOSE: To enhance operation efficiency by detecting temperature of a fixing device of a copying machine or the like, and estimating and indicating a waiting time in accordance with the detected temperature.
CONSTITUTION: A signal of thermistor 2 of the fixing device of a copier or the like is converted into a voltage signal, applied to A/D converter 5, and converted into a digital signal of 8 bits. It is further converted into a 10-bit BCD signal in binary- decimal converter 6, applied to decimal backward counter 7 as a preset input, and the value of counter 7 is displayed as a number via multiplexer 14 with display driver 8 on LED11 of 7 segments. When counter 7 comes to zero, flip-flop 16 is reset, wait lamp 13 is turned off, and copying data are displayed with driver 8, thus permitting estimation of a waiting time and facilitation of operation.
