<P>PROBLEM TO BE SOLVED: To provide a power supply device in which the number of components is reduced and which is simplified while having a plurality of power supply circuits. <P>SOLUTION: The power supply device includes a case 17. The power supply device is further provided with a substrate unit 18 which has two sheets of substrates 27a, 27b, on which main circuit 29a, 29b of the power supply circuits 28a, 28b are respectively mounted, and in which a common circuit 30 that is in common between the plurality of power supply circuits 28a, 28b is mounted on one of the substrate 27a out of the plurality of the substrates 27a, 27b, and that common circuit 30 is housed in the case 17 in which the plurality of substrates 27a, 27b are connected by a crossover wiring 31 in order to utilize this common circuit 30 in the other substrate 27b. <P>COPYRIGHT: (C)2012,JPO&INPIT |
