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.

Abstract: A printed circuit board is fixed to a resin insulation plate by using a first metal screw, and a metal casing is fixed to the resin insulation plate by using a second metal screw. The cuboid insulation plate is arranged to match the shapes of the long sides of the printed circuit board and the metal casing necessary for screw fixation. The first and second metal screws are attached to the resin insulation plate with a lateral shift. This makes it possible to reduce the insulation distance around the first metal screw on the printed circuit board and to increase the wiring pattern area and the component mounting space, realizing a reduction in the size of an electronic device.

Abstract: A sliding member that is provided in a front panel of a case so as to be movable in the vertical direction and is placed at a down position due to the own weight is provided with a window portion which covers and hides a screw insertion hole for fixing a unit when the sliding member is located at the down position and exposes the screw insertion hole when the sliding member is lifted to an up position. Further, the front panel is provided with an interlocking switch that controls the operation of the case unit in a manner such that the interlocking switch is turned on while being pressed by the sliding member lifted to the up position and is turned off while the pressing operation is released when the sliding member is located at the down position.
Abstract translation: 设置在壳体的前面板中以便能够在垂直方向上移动并且由于自重而被放置在下部位置的滑动构件设置有窗口部分，其覆盖并且隐藏用于固定的螺钉插入孔 当滑动构件位于向下位置时，当滑动构件被提升到向上位置时，单元暴露螺钉插入孔。 此外，前面板设置有互锁开关，该互锁开关以使得互锁开关在滑动构件被提升到向上位置的同时被打开的同时进行控制，并且在按压操作时被关闭 当滑动构件位于向下位置时被释放。

Abstract: A transformer is configured to include a pair of cores and that each have an inner leg, wherein a primary winding that is wound around a bobbin having a hollow into which the inner legs of the cores and are inserted, and a secondary winding that has a hollow into which the inner legs of the cores and are inserted and that is constituted of a conductor formed by die-cutting a metal plate into a ring, are dispersedly arranged over the inner legs of the cores and. The bobbin has bobbin support portions that come into contact with a surface of a printed circuit board on which the transformer is implemented.
