くなつていた。[Problems that the invention attempts to solve] The conventional positioning of printed circuit boards as described above,
In the fixing device, the lower part of the column 21 is usually screwed to one of the printed circuit boards 25 in advance, and then
This is fixed to the chassis of the case by other means, and then the other printed circuit board 24 is attached to the upper end of the column 21.
The screws are placed on top and screwed in from above, but not only is the assembly process cumbersome and requires a lot of man-hours, but the screws must be removed each time inspection or repair is required, which is extremely troublesome. In addition, since brass rods are generally used for the supports, the above-mentioned increase in man-hours and other costs have been a factor. Such problems become even more serious when the number of printed circuit boards increases or when a shield plate is attached.
