<p>PURPOSE: To unnecessitate periodical maintenance or exchange by executing the connection of a heating coil to a current transformer in a non-contact state. CONSTITUTION: One set of the current transformer 200 and two pieces of heating coils 100A, 100B for supplying electric current from the current transformer 200 are provided, and each of heating coils 100A, 100B heats a work W in order. A shifting mechanism 300 for shifting a loop-like terminal part 220 of output terminal 210 of the current transformer 200 relatively to loop-like conducting parts 141A, 141B respectively of current supplying conductors 140A, 140B of respective heating coils 100A, 100B, is provided. The shifting mechanism 300 is the one to face the loop-like terminal part 220 to the loop-like conducting parts 141A, 141B of the two heating coils 100A, 100B in order at a prescribed interval. The current is passed to each of the heating coils 100A, 100B with a secondary induction between the faced loop-like terminal part 220 and each of the loop-like conducting parts 141A, 141B.</p> |
