Abstract

PURPOSE: To perform use for both high and low voltages and to miniaturize a heater part by forming the heater of the low voltage system of an input power supply voltage by waveform heater constitution, forming the heater of a high voltage system by coil heater constitution and switching them corresponding to the low voltage system and high voltage system of the input power supply voltage. CONSTITUTION: The heater H3 used in a low power supply voltage system is formed in a waveform heater shape and the heaters H1 and H2 used in a high power supply voltage system are formed in a coil heater shape. In the case of performing use at the voltage of the low power supply voltage system of 100V, a switch S is short-circuited and the voltage is applied only to the heater H3 . In the case of performing use at the voltage of the high power supply voltage system of 200V, the switch S is opened and the voltage is applied to the heaters H1 , H2 and H3 . In such a manner, since the waveform heater constitution capable of efficiently taking the surface area of the heater is used at the time of using the low power supply voltage system requiring the heater of a large capacity with the large amount of a flowing current and the coil heater constitution capable of securing a required resistance value with a short length is used at the time of using the high power supply voltage system for which the heater of a small capacity is sufficient, a heater constitution part is efficiently miniaturized.
