Abstract

PURPOSE:To use a compact single electromagnetic coil for always effectively heating an iron body with simple constitution by providing a shift means for shifting the electromagnetic coil below the iron body on the basis of positional information obtained by a position detecting means. CONSTITUTION:When the temperature of an iron body 1 reaches a set temperature, an indicating lamp provided on an operating panel 17 is lit to inform a user of the iron body 1 reaching the set temperature, and then a position of the iron body 1 is detected. Positional data Pa of a temperature sensitive element 14a are stored in an accumulator M5. Since the positional data of the temperature sensitive element having the largest deviation temperature are thus stored in the accumulator M5, a shift device 11 is driven on the basis of the positional data stored in the accumulator M5, so that an electromagnetic coil 10 can be shifted below the iron body 1.
