An object of the invention is to provide a power supply controller for stopping an output of a power supply portion without adding a new circuit in the combined electronic equipment, and dispensing with ON/OFF operation of a power supply each time for every electronic equipment. The supply of power is controlled by supplying a control signal from a body CPU 10 to voltage conversion circuits (31, 32, 33) for supplying voltages having different levels to corresponding functional blocks (1, 2, 3), and the voltage conversion circuit for supplying a voltage having a level corresponding to a non-used functional block is controlled to be turned OFF, thereby reducing power consumption. <IMAGE>
