<P>PROBLEM TO BE SOLVED: To provide a graphic display device capable of contributing to an energy saving measure, relating to power supply from a power generation plant. <P>SOLUTION: In a present embodiment, the graphic display device includes a power source switching part, a power source control part, and a switch part. The power source switching part switches between a first power source part in which a DC power source used for operating a device is supplied from a commercial power source and a second power source part in which the DC power source is supplied from inside. The power source control part, during the period in which the second power source part is selected for operation by the power source switching part, the power source capacity required for the operation for accepting the input of an operation signal is supplied from the first power source part. The switch part provides the power source capacity required for the operation for accepting the input of the operation signal from the first power source part, independent of the power source supply from the second power source part having been switched by the power source switching part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
