<p>PURPOSE:To improve the reliability of power supply making/breaking operations of a power supply device, by starting the making/breaking operations when control signals from plural power supply controlling devices arrive by changing their arrival times. CONSTITUTION:Each of power supply controlling mechanisms SPC1 and SPC2 is equipped with A and B connector groups and each connector group has two output terminals. The priority of the A connector group of the SPC1 is higher than that of the B group and, on the contrary, the B connector group of the SPC2 has the higher priority. The power supply making signal of the SPC1 is supplied from one A1 of its output terminals to a power supply section PW1 at a time T1 and the power supply making signal of the SPC2 is supplied from one A1 of its output terminals at another time T3. When arrival of at least one of the signals supplied at a time interval 2t between the times T1 and T3 is detected at a logical operation circuit LG, the power supply section PW1 is actuated.</p> |
