にタツピンねじ２３で固定して構成されていた。 An example of a conventional thin radio receiver will be described with reference to FIG. That is, the thin radio receiver 20 is equipped with a battery 5, non-moving electric parts P1 to P3 , a variable capacitor 6 and its knob 7, which are movable electric parts, a volume not shown and its knob, etc.
The adjusted flexible circuit board 3 was sandwiched between a front side part 21 and a back side part 22 of the cabinet and fixed with tassel pin screws 23.

With the above-mentioned cabinet structure, there is a space between each component and the inner surface of the cabinet so that even if the front part 21 and the back part 22 of the cabinet are pushed and bent, they do not come into contact with the components on the circuit board 3. The need to provide gaps A and B has been a major obstacle in making the radio receiver even thinner. Furthermore, since the cabinet is composed of a front side part 21 and a back side part 22, two sets of molds are required for molding. Conventional cabinet structures, such as the need for tassel pin screws 23, were not necessarily satisfactory in terms of productivity and cost.

According to the cabinet structure of the present invention, it is no longer necessary to provide a gap between the electrical components and the inner surface of the cabinet, which was a drawback of the conventional example, and it is possible to eliminate obstacles when making the radio receiver thinner. Additionally, the metal substrate prevents the cabinet from buckling due to mechanical bending. Furthermore, since the flexible circuit board is supported on the metal substrate, deformation of the flexible circuit board during the cabinet molding operation can be prevented, and high precision cabinet structures can be obtained in high yields.
