PURPOSE:To provide a heating temperature controller for shortening the rise time of a heating device having the slowest temperature rise time and shortening the whole rise time of the device by controlling a previously set current supply rate for the heating device so as to increase it. CONSTITUTION:The heating temperature controller is provided with plural heating devices 20, 40 respectively having heating means 13, 33 for heating respective targets 11, 31 by current supply, temperature detecting means 17, 37 for detecting the temperature of the targets 11, 31 and lower current supply ratio controlling means 15, 35 for controlling the current supply rates of respective heating means 13, 33 based upon detected temperature, plural current supply rate detecting means 21, 41 for detecting the current supply rates of the means 13, 33 of plural heating devices 20, 40, a current supply rate comparing means 23 for comparing respective current supply rates detected by respective means 21, 41 and discriminating the heating device having the most delayed temperature rise, and an upper current supply rate controlling means 44 for controlling the heating device discriminated by the means 23 as a device whose temperature rise is most delayed so as to change the current supply rate of the heating means in the discriminated heating device. |
