（例えば、実開昭６０−３７０４０号公報）。(Prior art) When joining the butt parts of two (or more) carpets laid on a floor surface, conventionally, a heat-sensitive adhesive tape is used, which is a layered hot-melt adhesive on the surface of a conductive base material. Place it on the butt part of the carpet on the floor,
The butt parts of the two carpets are placed on this heat-sensitive adhesive tape, and then an electric current is passed through the conductive base material to heat the conductive base material, melting the adhesive and sealing the butt parts of the carpets. A method of joining has been used (for example, Japanese Utility Model Application No. 60-37040).

Incorporate an output adjustment circuit to control the oscillation frequency of the oscillation circuit. As a result, the heating effect on the conductive base material, which varies depending on the thickness of the carpet, is made approximately equal by keeping the output power constant. In addition to this output adjustment circuit, an indicator light circuit is provided that lights up based on the current consumption of the output circuit. As a result, if the carpet comes off the joint, the indicator light goes out, allowing you to check whether the ends of the carpet are properly joined.
