<P>PROBLEM TO BE SOLVED: To provide a power supply adapter device that dispenses with an output cord corresponding to each voltage, and is singly adaptable to electronic apparatuses of a variety of voltages. <P>SOLUTION: The power supply adapter device comprises: a voltage sweep means 1 that applies voltage sweeping to the connected electronic apparatus E; a detection means 13 that detects the change of current in the voltage sweeping; and a voltage setting means 14 that monitors the change of the detected current and sets a voltage value obtained when the change of the current satisfies prescribed conditions to a voltage fed to the connected electronic apparatus E. When a variety of the electronic apparatuses E are connected, the voltage sweeping is applied to the connected electronic apparatus E, and a value of a voltage fed to each of a variety of the electronic apparatuses E is automatically set in accordance with the change of the current in the voltage sweeping. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
