Abstract
A first printed circuit board on which a heatsink having a discrete semiconductor device attached to it and first capacitors for smoothing an electric current after a conversion from AC to DC are mounted is arranged in the horizontal direction of a bottom portion of a device casing. On the first printed circuit board, various electronic components such as a resistor, a diode, a capacitor, a coil, etc. are mounted in addition to the heatsink and the first capacitors. Further, in an in-device-casing vacant space in an upper portion of the heatsink mounted on the first printed circuit board, a second printed circuit board on which second capacitors for performing smoothing upon a conversion from AC to DC are mounted is arranged orthogonally to the first printed circuit board in the device spacing.
