The control unit (16) includes a first A/D converter (16a) to which a first reference voltage (Vref1) and a first output outputted from the system voltage detection circuit (31) are inputted, a second A/D converter (16b) to which a second reference voltage (Vref2) and a second output outputted from the system voltage detection circuit (31) are inputted, a comparison portion (16c) comparing an output from the first A/D converter (16a) with an output from the second A/D converter (16b), and a detection accuracy determination portion (16d) determining a detection accuracy of the voltage of the system power supply (20) based on a comparison result.",
