ABSTRACT:
A heating apparatus that utilizes a heating member for heating a desired subject detects the temperature of the subject being heated. This apparatus further generates a plurality of preset reference set points, compares these reference signals with the detected temperature. An energizing control circuit controls the supply of electricity to the heating member in accordance with the comparison result. The apparatus retains the signal generated from the comparison result, and as a result of this signal, changes the reference set point to cause the apparatus to heat at a new temperature setting.
