PURPOSE:To provide a power source controller in which a voltage drop need not be considered when a DC current is supplied from DC current supply means to a load. CONSTITUTION:When a load 12 is ON, a DC current is supplied from DC current supply means 13 to a load 12 through first switch means 18, while when the load 12 is OFF, the means 18 is turned OFF, and the DC current is supplied to the load 12 through a diode 14. Further, when an external DC current is input from external DC current supply means 10, second switch means 19, 20 are opened irrespective of ON/OFF of the load 12, and an external DC current is supplied to the load 12. |
