    • A heater controller performs on/off control of a plurality of heaters and includes a storage unit that stores therein a plurality of pattern sets. Each of the pattern sets includes a plurality of heater-on/off patterns for respectively controlling the heaters. The heater controller calculates a reference value representing an average of values of electric power supplied to the heater controller over a predetermined period of time; calculates, for each of the pattern sets, an output power value to be supplied to the heaters when the heaters are turned-on according to the heater-on/off patterns included in the pattern set; calculates, for each of the pattern sets, a difference between the reference value and the output power value; selects, from the pattern sets, one pattern set having a smallest difference; and performs on/off control of the heaters according to the heater-on/off patterns included in the pattern set thus selected.
    • 加热器控制器执行多个加热器的开/关控制,并且包括其中存储有多个图案组的存储单元。 每个图案组包括用于分别控制加热器的多个加热器开/关模式。 加热器控制器计算表示在预定时间段内提供给加热器控制器的电力值的平均值的参考值; 针对每个图案组计算当加热器根据包括在图案组中的加热器开/关模式接通时提供给加热器的输出功率值; 对于每个图案集合,计算参考值和输出功率值之间的差; 从图案集中选择具有最小差异的一个图案组; 并且根据包括在所选择的图案集中的加热器开/关模式来执行加热器的开/关控制。
