The antenna 22 is attached to the antenna support plate 34 by the screws inserted through the four screw insertion holes 3406 of the antenna support plate 34 being screwed into the female screws 2206.

In this embodiment, rail plate 26, slide member 28, holding member 30, connecting member 32, antenna support plate 34, screw for attaching rail plate 26 to rear surface 18, screw for attaching holding member 30 to slide member 28, The screw for attaching the holding member 30B to the main body 30A and the screw for attaching the antenna 22 to the antenna support plate 34 are all formed of a non-conductive material such as synthetic resin, so that the radio wave is guided to the antenna 22 without being disturbed. It has been.
In the present embodiment, as shown in FIG. 3, with the antenna 22 positioned at the second position (b), the interval ΔL formed between the reflector 19 and the antenna 22 is to be received. Where λ is the wavelength of the radio wave, the radio wave reflected by the reflector 19 is efficiently reflected and guided to the antenna 22, thereby The gain of the antenna 22 is improved.

In this embodiment, as shown in FIGS. 1 and 3, the lower edge of the slide member 28 is brought into contact with the stopper 2610 of the rail 26, so that the antenna 22 is positioned inside the contour of the front surface 16 of the housing 14. The second position (b).
Further, the slide member 28 located at the second position (b) is moved upward as shown in FIG. 4, and the engagement recess 2810 of the slide member 28 is clicked of the click mechanism 36 as shown in FIGS. By engaging with the engaging claws 3602, the antenna 22 becomes the first position (A) located outside the outline of the front surface of the housing 14.
Therefore, for example, the television apparatus 10 is installed indoors, and there is a window opened outdoors behind the television apparatus 10 so that radio waves travel from the rear of the housing 14 toward the antenna 22 through the window. In such an installation environment, the antenna 22 may be set to the first position (A) or the second position (B). At any of the first and second positions (A) and (B) of the antenna 22, radio waves can be efficiently guided to the antenna 22, which is advantageous for improving the gain of the antenna 22.
In this case, when the antenna 22 is set to the second position (b), most of the antenna 22 is located inside the outline of the front surface 16 of the housing 14, so that the antenna 22 can be made inconspicuous. This is also advantageous for improving.
In particular, in the present embodiment, since the interval ΔL formed between the reflector 19 provided in the housing 14 and the antenna 22 is about λ / 4, the antenna 22 is moved to the second position (b). Then, the radio wave can be efficiently reflected and guided to the antenna 22 by the reflection plate 19, which is more advantageous in securing the gain of the antenna 22. In addition, by separating the antenna 22 from the housing 14 in this manner, it is advantageous for suppressing the influence of unnecessary radiation generated from an electronic circuit or the like inside the housing 14 on the antenna 22.
In an installation environment where there is a window in front of the television apparatus 10 and radio waves travel from the front of the housing 14 toward the antenna 22 through the window, the antenna 22 is set to the first position (A). As a result, the antenna 22 is located outside the outline of the front surface 16 of the housing 14, so that radio waves are blocked by the display panel 12, the printed circuit board, the electronic component, the frame made of a conductive material, etc. disposed inside the housing 14. Thus, the antenna 22 is efficiently guided to the antenna 22, which is advantageous in improving the gain of the antenna 22.

In this embodiment, since the spherical portion 3202 of the connecting member 32 is sandwiched between the spherical concave portions 3002 and 3010 of the holding member 30, the antenna 22 is in the first position (A) or the second position ( B) the antenna 22 can be tilted in any direction and the rear surface 2204 (radiation surface) of the antenna 22 can be directed in the traveling direction of the radio wave, so that the radio wave is efficiently guided to the antenna 22. This is advantageous in improving the gain of the antenna 22.
Further, since the spherical portion 3202 of the connecting member 32 is rotatably supported by the spherical bearing 30C of the holding member 30, the antenna 22 passes through the center of the spherical portion 3202 and the direction in which the antenna 22 is directed (antenna 22 And an axis extending in the direction perpendicular to the rear surface 2204 (radiation surface).
Therefore, the radio wave is efficiently transmitted by rotating the attitude of the antenna 22 by 90 degrees around the axis depending on whether the radio wave of television broadcasting is transmitted with horizontal polarization or when transmitted with vertical polarization. It can be guided to the antenna 22 well, which is advantageous in improving the gain of the antenna 22.

Although the case where the antenna 22 has a rectangular plate shape has been described in the present embodiment, the shape of the antenna 22 may be, for example, a disk shape, and various conventionally known shapes can be employed.
In this embodiment, the rear surface 2204 (radiation surface) of the antenna 22 extends on a plane. However, the rear surface 2204 (radiation surface) of the antenna 22 is a cylindrical surface, spherical surface, or It may have a curved surface. In other words, in the present invention, the “plate shape” of the “plate-like” antenna includes a plane and a curved surface.
However, if the rear surface 2204 (radiation surface) of the antenna 22 extends on the plane as in the present embodiment, a large projected area of the rear surface 2204 (radiation surface) viewed from the traveling direction of the radio wave can be secured. This is advantageous in improving the gain of the antenna 22.
