【発明の名称】印刷機の熱源に対する電力供給制御方法及びその電力供給制御装置
Document Type and Number:
Japanese Patent JP3088421
Kind Code:
B2
Abstract:
A method of controlling the power supply to heat sources of a printer and an apparatus therefor are disclosed. The apparatus for controlling power supply to heat sources of a printer comprising: a heat generating portion (60) having a plurality of heat sources; a power supply unit (70); a switching portion (80) having a plurality of switches installed so as to connect or disconnect the power supply from the power supply unit to the individual heat sources; thermal sensors (91-94) for sensing the temperatures of heat-supplied objects corresponding to the heat sources and generating corresponding temperature signals; and a power supply controller (100) for adjusting the on times of the heat sources so that all periods of power supply to the heat sources do not overlap while reading the output signals from the thermal sensors paired with the respective heat sources, and controlling the switching portion so that the temperatures of the heat-supplied objects are maintained within the respective preset temperature ranges. According to the method of controlling the power supply to heat sources of a printer and the apparatus therefor, the maximum consumed power of employed heaters can be reduced. Therefore, the required power capacity of the power supply unit and the allowable amount of current of the power supply lines can be lowered.
