<p>PURPOSE: To provide an information processor which has a simplified interface between a power unit and a system device. CONSTITUTION: The information processor 1 has the power unit 2 which converts an alternating current supplied from a power source into a direct current, an output line 60 which is connected to the power unit 2, and the system device 3 which receives the direct current through the output line 60. The system device 3 is provided with a secondary battery 33 which is charged with the direct current. The power unit 2 has a switching circuit 26 which controls whether or not the direct current is outputted to the output line 60 according to a given instruction and a control circuit 22 which communicates with the system device 3 by using the output line 60 when the direct current is not outputted to the output line 60. The system device 3 has a CPU part 30 which is supplied with electric power from the secondary battery 33 and communicates with the power unit 2 by using the output line 60 when the direct current is not outputted to the output line 60.</p> |
