Abstract: PURPOSE:To reduce the capacity rating of a power source and to avoid cost increase by starting the supply of current to another unit module when current which is supplied to one unit module becomes lower than a specified value. CONSTITUTION:A control part 6 is operated, and a switch part 4a is turned ON for the constant temperature oven 5a among four constant temperature ovens 5a-5d. Thus, a power source is turned ON. At this time, a heater current which is supplied to the constant temperature oven is detected with a current detecting part 3a. When the heater current is decreased to a preset value or less from the initial maximum value, the control part 6 controls a switching part 4b so as to make the switching part 4b ON for the next constant temperature oven 5b. Then, the heater current is supplied to the constant temperature bath 5b in the same way described above. When the heater current is decreased to a preset value or less, the control part 6 controls a switching part 4c so as to make it ON for the next constant temperature bath 5c. In this way, the power source is sequentially inputted into each unit module with a set time interval. Thus, the capacity rating of the current can be reduced.
