A load drive apparatus includes a drive signal control circuit for generating multiple drive signals, each of which is provided to each of the loads. The drive signal control circuit changes a phase of the drive signals in accordance with the number of the loads to equalize a phase difference between each of the drive signals. Therefore, it is less likely that all the loads are simultaneously driven. A concentrated increase in a load current can be prevented so that an increase in peak values of noise and heat production can be prevented.
