<p><P>PROBLEM TO BE SOLVED: To provide an information processor for receiving the supply of a power from an external device connected to a connector by using a power source line for supplying a power to the external device connected to the connector even during operation. <P>SOLUTION: When an external device 2 is connected to a USB connector 15, a computer 1 recognizes that the external device 2 is a normal USB device, and sets a power source line in an input/output control circuit 16 so as to start power supply by a USB power source supply circuit 17. Afterwards, when the external device 2 connected to the USB connector 15 is a solar battery unit 2, the computer 1 performs the switching of a power source line in the input/output control circuit 16, and starts the charging of the battery 18 by a charging circuit 19 using a power to be input from the solar battery unit 2. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
