Abstract

PURPOSE:To display lapse of warming-up time till a copying machine reaches a stable region and to eliminate wasteful wait time, by controlling plural displays in accordance with detection of heater roller temperature. CONSTITUTION:An output issued from a thermistor 1 by detecting temperature of a heater roller is applied to calculation amplifiers 101-105 in parallel forming comparators set to different reference voltages with resistances 106-110, etc. of a display control circuit 100. As a result, the transistors of a driver 112 are caused to conduct in succession in accordance with the temperature to control lighting of corresponding LED 11-15, thus permitting wasteful wait time to be eliminated by displaying lapse of the warming-up time till reaching the stable region with these LED11-15.
