PROBLEM TO BE SOLVED: To make a power source small in size, light in weight and low in cost and to facilitate the distribution of electric power to other loads by controlling first and second loads so as to evade timewise overlapping of peak currents of the first and the second loads when setting the condition of executing the specified job. SOLUTION: A current R1 for supplying to an image read out means and currents S1, S2, S3 for supplying to an image output means are described. The current S1 is the current supplying to the image output means of the conventional device and is shown for the comparison. A timing between a read out operation and an output operation is controlled so as to shift phases of peak currents each other as similarly as the current S2 in order to evade a large current. That is, by shifting the phase against to the current R1, the peak current Q of the waveform S2 of the image output means occurs at times of t3 and t7 and consequently the maximum peak current does not become P+Q and the maximum current can be reduced to P (or Q). The current S3 controls shifting a time of occurrence of the peak current Q by changing a fluctuation cycle. |
