PURPOSE:To always recognize and control power source load capacity by a system itself by allowing a CPU to detect the attached state and the operated state of an optional part at that time by referring to a ROM table and controling the power source load capacity of the system according to the detected result. CONSTITUTION:The operated state of a main body and the attached state and the operated state of the optional part are detected by the CPU 13 so as to control the power source load capacity of the entire system. Thus, the power source load capacity of the system is calculated from the data on the power source load capacity incorporated in a ROM 14 on a control substrate 10, so that the power source load capacity is always recognized and controlled by the system itself. By detecting the state of the system according to the temperature of each part of the system by using a temperature detecting circuit such as a thermistor 20, the power source load capacity of the system is controlled. Since the temperature of each part of the system is detected, the power source load capacity in each state of the system is recognized and controlled by the system itself. |
