A temperature rising part heater 32 and a heat reserving part heater 33 are installed below the heating plate 30, and a power supply 122 is connected to the heaters 32, 33 to heat the heating plate 30. A power regulating unit 138 is interposed between the heat reserving part heater 33 and the power supply 122, and a control circuit 140 is connected to the power regulating unit 138 to control the operation of the power regulating unit 138. At the time of starting the device, power larger than that in the case of heat reserving by the heat reserving part heater 33 is supplied from the power regulating unit 138 controlled by the control circuit 140. |
