Abstract
There is provided a prioritization circuit which selects one of a system power supply and a secondary battery unit as a selected supply source and the other as a non-selected supply source and which causes supply of electric power with a higher priority from the selected supply source to a power supply unit, wherein the non-selected supply source is connected to the power supply unit through a diode element which generates a voltage drop and the selected supply source supplies electric power to the power supply unit without passing through a diode element.
