ービス性が悪いという欠点を有していた。Conventional configurations and their problems In recent years, electronic devices such as tuners and receivers have become more multi-functional, and the area of printed circuit boards has been forced to expand in order to accommodate additional functional circuits. On the other hand, there is a tendency for electronic devices to have smaller external dimensions. For this reason, electronic devices have conventionally been constructed by storing printed circuit boards in two layers in the device body to secure the board area without increasing the size of the device body. However, in conventional electronic devices, printed circuit boards are held in two layers on the chassis structure that constitutes the main body of the device, so the chassis structure has a mounting section for the upper printed circuit board in addition to the mounting section for the lower printed circuit board. The problem was that it was difficult to assemble because each printed circuit board had to be fixed with mounting screws. Additionally, the components on the lower printed circuit board are covered by the upper printed circuit board, resulting in poor serviceability.

According to this configuration, it is possible to attach the other ends of the printed circuit boards of each layer attached to the independent rear panels to the inner surface of the front panel constituting the device body, and then to connect the independent rear panels. This has the advantage of improving ease of assembly and service.

is a sub-rear plate, which is attached by mounting screws 11 so as to cover the cutout 2a of the main rear plate 2. A first terminal plate 7 is attached to the sub-rear plate 1 with mounting screws 8, and a second printed circuit board 3 is attached to this terminal plate 7. On the other hand, a second terminal plate 9 is attached to the main rear plate 2 with mounting screws 10, and a first printed circuit board 4 is attached to this terminal plate 9. The first and second printed circuit boards 4 and 3 are attached to the inner surface of the front panel 5 with mounting screws 12 and 13, and are attached to the bottom surfaces of the front panel 5 and the main rear panel 2 with mounting screws 14 and 15. A bottom plate 6 is attached.
