で不利である。(B) Prior Art As shown in FIG. 1, a conventional tuner device has a main printed board 2 for the tuner circuit disposed inside a metal casing 1, and a sub-board installed in the VHF tuner section 3 at right angles to the main printed board 2. A printed circuit board 4 is arranged. In addition, the external connection terminal 6 of the tuner device is 1
One end of the lead is connected to the tuner circuit by passing through the main printed board 2 and fixing it by soldering to the copper foil part on the back of the main printed board 2, as shown in Fig. 2. be done. In addition, in Figure 1, 3a is
The RF stage 3b of the VHF tuner section 3 includes a local oscillation stage and an IF stage. Reference numeral 7 denotes a UHF tuner section, which includes an RF stage 7a, an interstage primary sequential circuit 7b, an interstage secondary circuit 7c, and a local oscillation stage 7d. 8 is
This is a UHF input terminal. Incidentally, in recent years, tuner devices have been required to be downsized. On the other hand, when configured for wideband reception compatible with CATV, it is inevitable that the number of circuits and components will increase as the reception band expands, so a problem arises in that conventional tuner devices cannot cope with miniaturization. Further, in the conventional tuner device, the external connection terminal 6
This is disadvantageous in terms of improving the efficiency of manufacturing work because it must be bent or inserted into the main printed board 2.

ので機械的な強度が弱いという欠点を有する。 Another conventional technique has been proposed in which the secondary printed board is also used as a part of the tuner housing, as described in Japanese Utility Model Publication No. 43-817. However, the sub-printed board proposed in this prior art only forms an inductance coil with the copper foil, and is not designed to attach components of a tuner circuit. Furthermore, this prior art has the disadvantage that mechanical strength is weak because the sub-printed board is used as the housing wall.

A patterned copper foil 10 is provided at , and one end of the external connection terminal 6 is fixed by soldering. Chip components 11 such as resistors and capacitors are also soldered. As shown in FIG. 4, the external connection terminal 6 is formed as a feedthrough capacitor having a soldering portion 6a to the housing wall 5 and a fitting portion 6b at the center of a terminal pin 6c. In this case, if the thickness of the casing wall 5 is thin, the remaining portion 6b' of the fitting part 6b protrudes toward the inner surface of the casing wall 5, so that the casing wall 5 and the sub-printed board are connected to each other as shown in FIG. There is a gap of 1 between 9 and 9.
2, resulting in an unstable structure. In contrast, the tuner device of the present invention has a housing wall 5 as shown in FIG.
When external connection terminals are inserted into the ribs 13 which protrude outward and are fixed by soldering, the housing wall 5 and the sub-printed board 9 are brought into close contact with each other, and no gaps are formed between them, resulting in a stable structure. The connection between the sub printed board 9 and the main printed board 2 is achieved by bonding the connecting copper foils 14 and 15 of the two with solder 16, as shown in FIG.

る。(f) Effects of the invention According to the invention, the sub-printed board 9 is arranged so as to overlap the side of the housing wall 5, and furthermore, the sub-printed board 9 incorporates circuit components to play a part of the tuner circuit. This has the effect of making it possible to reduce the size of a tuner that requires many parts, such as a tuner compatible with CATV reception. In addition, since it is arranged so as to overlap the housing wall 5, when the housing wall 5 is used for attaching an external connection terminal, the tip of the terminal can be directly attached to the sub-printed board 9 without being bent.
Workability is good because it can be inserted and fixed into the first
Since it is not necessary to insert and fix the main printed board 2 as shown in the figure, it is possible to eliminate the inconvenience of wasting the effective space of the main printed board 2 by connecting the terminals.
更に、本考案のチユーナ装置では副プリント板

分である。 Furthermore, in the tuner device of the present invention, the sub-printed board does not also serve as a housing wall, so the mechanical strength is sufficient.
