を採っている。なお１はプリント基板であり、２は回路
素子金示す。Conventionally, when assembling a transmitter/receiver circuit on a printed circuit board, if part or all of the circuit must be electrostatically shielded from other circuits in order to eliminate crosstalk, for example, the circuit must be shielded as shown in Figure 1. In the circuit part that is engraved with
The method is to cover it with a shield case 3 made of metal. Note that 1 is a printed circuit board, and 2 is a circuit element.
ところがこのような手段によるときは場所を占めること
になるし、また生産上それだけ取付けに手間を要するな
ど問題であった。However, when using such a method, it takes up a lot of space, and there are problems in terms of production, such as the fact that it takes more time and effort to install.

る生産性の面で大きな改善を施したものである。In contrast, in the present invention, a tongue piece made of a thin metal plate or a laminated layer of a thin metal plate and a glass plate is integrally connected to a flexible printed circuit board on which a circuit is assembled, and the tongue piece is connected to a low impedance potential. This optical communication transmitter/receiver is characterized in that the circuit to be shielded is covered with this tongue piece, and the shield case has greatly improved the space occupied by the shield case and the productivity in assembly.
以下図面に示す実施例について説明する。The embodiments shown in the drawings will be described below.

がれる。In FIGS. 2A and 2H, a 4Fi flexible printed circuit board is shown, and 5 is a tongue piece formed integrally with the flexible printed circuit board 4. For example, the tongue piece 5 is entirely made of a laminate of a thin metal plate and a thin resin sheet, or a flexible printed base. 4, the thin synthetic resin sheet portion is integrally connected to the flexible printed circuit board 4.

もできる。In another embodiment, as shown in FIGS. 3A and 3B, the circuit part of the receiver 6 and the circuit part of the transmitter 7 are separated and placed and connected on the flexible printed circuit board 4, and the circuit part of the receiver 60 is separated. It is also possible to have a configuration in which the tongue piece 5 is folded upward and the circuit part of the transmitter 7 is further overlapped on the folded tongue piece 5.
そして、舌片５は低インピーダンス（アース電位）の電

とはなく、全体をコンパクトにまとめることができる。According to the present invention, it is well understood that productivity is significantly improved because the flexible shielding tongue integrally formed with the flexible printed circuit board simply covers the area to be shielded. Due to the flexibility of the tongue piece, as shown in the embodiment in FIG. Arrangement If the flexible printed circuit board parts are all overlapped in one position, the whole structure can be made compact without being bulky.
