Abstract
The power supply controller serves to distribute electric power to each part of the electronic apparatus for operation, and the electric power can be fed from the AC power source, the fuel cell unit and the secondary battery unit. The power supply controller transmits the data signal indicating from which of the AC power source, the fuel cell unit and the secondary battery unit, the electricity is fed, to the CPU via the built-in register. The CPU displays the use status of the AC power source, the fuel cell unit and the secondary battery unit on the LCD via the display controller.
