る。Description: TECHNICAL FIELD The present invention relates to a structure of a transceiver of a portable wireless device, and in particular, the transceiver is separated into a transmitter and a receiver, and the whole transmitter / receiver is used as a controller. The present invention relates to a shield structure isolated from a circuit.
移動無線機では、送信部，受信部及び制御部をそれぞれ
隔離し、お互いの高周波結合を抑えることが好ましい。
（第３図参照）しかしながら従来の携帯無線機では実装

形状のばらつきを反映した複雑なシールド構造となって
いる。（第４図参照）。In the mobile wireless device, it is preferable to separate the transmission unit, the reception unit, and the control unit from each other to suppress high frequency coupling with each other.
(Refer to Fig. 3) However, it is difficult to obtain a sufficient shield effect in the conventional portable wireless device due to restrictions such as mounting volume, weight or component shape. Even if it is possible, a complicated shield structure that reflects variations in component shape is possible. Has become. (See FIG. 4).

な構造（第３図参照）では、シールド性は十分であるが
重量や実装体積の点で携帯用無線には不向きである。A structure that is often used in in-vehicle radios, that is, a structure in which the inside of an aluminum die-cast housing is partitioned by walls, and when the housing is assembled, spaces are created that are separated from each other by metal plates (see Fig. 3). ), The shield property is sufficient, but it is not suitable for portable radio in terms of weight and mounting volume.

うという欠点がある。（第４図参照）。Therefore, in order to overcome the drawbacks, it is necessary to replace the aluminum die-cast with a thin metal plate, but still try to shield between the transmitter, receiver and controller arranged so that the mounting efficiency is high. There is a drawback that it becomes a complicated shape. (See FIG. 4).

ゆえに容易には実現できない。In addition, there is generally an interaction between the transmitter and the receiver, and it is preferable that the transmitter and the receiver are integrated into one unit including the shield even when performing the respective tests.
The conventional portable wireless device cannot be easily realized due to its shield shape and complicated structure.

する。In order to solve the above-mentioned problems, the present invention provides a transmission panel and a reception panel having a printed circuit board on which only surface mounting components are mounted only on one side, and the non-mounting surfaces are opposed to each other, and a shield plate is provided between them. Place them in contact,
A configuration is adopted in which the transmission panel is surrounded by a frame that fixes the transmission panel and the reception panel, the shield and the transmission cover, and the reception panel is surrounded by the frame, the shield, and the reception cover.

金属板でできている。Next, the present invention will be described with reference to the drawings. FIG. 1 is a sectional view of an embodiment of the present invention. The transmitting panel 1 and the receiving panel 2 are mounted with surface mount components on only one side of the printed boards 10 and 20, and the surface mount components 11 to 14 and 21 to 24 are of low profile type so that the height of the mount components can be made uniform. It is being measured. Unmounted surface (flat surface) of transmission panel 1 and reception panel 2
The shield plate 3 is brought into contact with that of the transmission panel 1
And the receiving panel 2 are separated. The transmission panel 1, the reception panel 2 and the shield plate 3 are fixed to the frame 4 by means such as screwing and the shield plate 3 is in contact with the frame 4 so as to have the same potential. Transmission cover 5
Covers the mounting surface side of the transmission panel 1 and makes four contacts with the frame, and surrounds the transmission panel 1 together with the shield plate 3 and the frame 4. The reception cover 6 covers the mounting surface side of the reception panel 2 and is in contact with the frame 4, and surrounds the reception panel 2 together with the shield plate 3 and the frame 4. The shield plate 3, the frame 4, the transmission cover 5 and the reception cover 6 are all made of metal plates.

果がある。As described above, according to the present invention, the heights of mounted components are made uniform, and the transmitting panel and the receiving panel mounted on only one side are arranged so that their flat surfaces face each other, thereby transmitting with a simple shield structure. There is an effect that the panel and the receiving panel can be shielded, and the transmission / reception unit and other control units can be easily shielded. Further, since the transmission / reception unit is unitized including the shield, there is an effect that the transmission / reception unit including the interaction between the transmission unit and the reception unit can be easily tested with high reliability.
