PROBLEM TO BE SOLVED: To set the output of a heating section interlockingly with the absolute position of an operation section, to display the present output setting, to set the on/off and the increase/decrease of the output setting of the heating section by a single operation method by providing encoders outputting digital signals based on the displacement of the operation section and switches opened or closed near the end of the displacement of the operation section. SOLUTION: First and second operation means 61, 62 are provided with cylindrical operation knobs 616, 626. Encoders SW614, SW624 are arranged at the center sections of the operation knobs 616, 626 to detect the rotations of the operation knobs 616, 626. Lugs 617, 627 are provided on the peripheral sections of the operation knobs 616, 626, and microswitches SW615, SW625 are pushed by the CCW rotation ends of the operation knobs 616, 626. The on/off and output setting of weak and strong can be set by one kind of operation method to rotate the operation knobs 616, 626 CW or CCW. |
