PROBLEM TO BE SOLVED: To make it possible to continuously supply electric power only to parts needed for a function even when a power switch is turned off. SOLUTION: A power source part is provided with a 1st switch 61 which is provided in parallel to a power switch 13, 2nd switches 62 to 65 which are interposed in power supply lines L2 to L5 to input/output equipment parts 22 to 24, and a switch control signal output part 66 which outputs a 1st switch control signal S1 switching on and off the 1st switch 51 and 2nd switch control signals S2 to S5 switching on and off the 2nd switches 62 to 65. The states of the 1st switch control signals S1 and 2nd switch control signal S2 are optionally set and the electric power is continuously supplied only to the functionally needed parts when the power switch is turned off. |
