Title: Temperature control circuit for heat fixing device
Inventor: HASHIZUME HIROSHI
IPC: G03G15/20
Filed: 1988-03-09
Abstract: PURPOSE:To perform efficient temperature control by providing three high, intermediate, and low stages of reference temperature, and selecting the high or intermediate reference temperature according to whether the detected temperature of a temperature sensor is high or not and then driving the heat fixing device. CONSTITUTION:Comparators 6a-6c input reference voltages corresponding to the three stages Ta-Tc of reference temperature (Ta>Tb>Tc). A FF 13 opens a gate 12b when a comparison result indicating that the detected temperature of the thermistor 1 is lower than the temperature Tc from the comparator 6c is obtained. A SSR 8, therefore, inputs the outputs of the comparator 6c through the gate 12b and performs on-off control at the temperature Tb. When a comparison result of the comparator 6a which indicates that the detected temperature of the thermistor 1 reaches the temperature Ta is obtained, the FF 13 opens the gate 12a and performs on-off control at the temperature Ta. Consequently, temperature control which has an extremely small overshoot at the time of a temperature rise is realized.
