PURPOSE:To make it possible to efficiently output power corresponding to a required operation and required output power information by control signals supplied from the outside. CONSTITUTION:When outputting 4.8 V as power outputs 71 and 72 from the power supply portion, a terminal a and a terminal c of a switch 1 are connected by a control signal A, further, switch SW2 is turned on by a control signal B; and the power of 4.8 V can be output by serial connection of batteries D1 to D4 by connecting a terminal a and a terminal c of a switch SW3 by means of control signal C. Also, power of 2.4 V can be output by the serial connection of batteries D1 and D2 by connecting the terminal b and the terminal c of the SW1, by releasing the switch SW2 with the control signal B and by connecting the terminal b and the terminal c of the twitch SW3 by the control signal C. |
