Abstract: PURPOSE:To prevent harmful noise from being generated and to extend a substantial life of a heater by a method wherein an electrical energization of the heater is controlled by a heater control signal which is formed on the basis of a pulse signal generated every time a voltage wave form of a power supply is crossed with a zero point. CONSTITUTION:A power supply frequency synchroneous pulse generating circuit 30 may generate a pulse signal (p) having the same period and same phase as that of a voltage wave form every time a voltage wave form of an AC power supply 60 is crossed with a zero point. This pulse signal is inputted to a micro-computer 20 through an external interrupting signal input terminal 24. A heater power control circuit do may control a turning-on or turning-off of a bi-directional switching element 44 in response to a heater control signal (q) got from heater control signal output terminal 26 to cause an electrical current of the AC power supply 60 to be flowed to the heater 6 by a desired period of time. Since the heater control signal for controlling an energization of the heater 6 is formed in response to a pulse signal generated every time the voltage wave-form of the power supply is crossed with a zero point, harmful noise is not generated and high electrical shock is not applied the heater.
