PROBLEM TO BE SOLVED: To form a ON/OFF sequence of power supply and signal only with the hardware. SOLUTION: A power supply controller 210 generates a control signal S1 for instructing the timing for supply of power source and power supply OFF to a control object unit 100. A delay circuit 220 generates a delay control signal S2 of which supply timing of power source is delayed from the control signal S1. A control signal selection circuit 230 generates a timing control signal S3 for controlling ON/OFF of the power switch 250 from the control signal S1 and the delay control signal S2. The power switch 250 turns ON and OFF the supply of power source to the control object unit 100 in the timing of the timing control signal S3. A signal system ON/OFF controller 260 receives the delay control signal S2 to delay the start of supply of signal to the control object unit 100 from the start of supply of power source, and mere quickly starts the OFF condition of signal than the start of OFF condition of power supply. |
