とが多い。However, this German spatial propagation network is constructed by using a transmitting/receiving device installed on the ceiling as a repeater, and installing multiple terminals each with a transmitting/receiving device that communicates data with this transmitting/receiving device by spatial propagation. . In this case, as shown in FIG. 1, the transmitting/receiving device 2 installed on the ceiling 1 generally has a wide spread angle θ to enable data communication with, for example, all the terminals installed in the room.
It is set to have a directivity of l. On the other hand, the transmitting/receiving devices 6a and 6b installed in the terminals 5a and 5b installed on the floor 4 are directed only towards the transmitting/receiving device 2 in order to prevent multinoise interference and interference with other transmitting/receiving devices. The directivity is often set at a narrow angle θ2 that is sufficient for .
ところで、このようにしてネットワークを構成する場合
、端末５ａ、５ｂの送受信ＭＵ ６ ａ 。By the way, when configuring the network in this way, the transmitting and receiving MU 6 a of the terminals 5a and 5b.
６ｂの指向方向をそれぞれ精度良く、天井１に設けられ

方向を合せることがめんどうであった。Data communication between 6b and 6b is performed using radio waves and infrared light, so to know whether the above alignment has been performed accurately, it is necessary to actually perform data communication, which is inconvenient. Ta. In addition, this type of terminals 5a, 5b are often portable and moved, and it is troublesome to align the pointing directions of the transmitting/receiving devices 6a, 6b each time.
本発明はこのような事情を考慮してなされたもので、そ

供することにある。The present invention has been made in consideration of these circumstances, and its purpose is to provide a highly practical space in which the pointing direction of a transmitter/receiver installed in a terminal can be easily and accurately aligned with a desired direction. An object of the present invention is to provide a transmitting and receiving device for a propagation network.
本発明は所定の指向性を有する送受信機に一体的に、そ
の指向方向に、指向幅より狭い広がり角の可視光線を発
生する光源を設け、上記可視光線を用いて送受信機の指
向方向調整を可能としたものである。The present invention provides a transmitter/receiver having a predetermined directivity with a light source that generates visible light with a spread angle narrower than the directivity width in the directivity direction of the transmitter/receiver, and uses the visible light to adjust the directivity of the transmitter/receiver. This made it possible.
従って本発明によれば、送受信機と同一方向に指向する
可視光線を利用してその指向方向を容易に設定すること
ができるので、従来の煩わしい調整が全く不要となる。Therefore, according to the present invention, the directivity direction can be easily set using visible light rays directed in the same direction as the transmitter/receiver, so that the conventional troublesome adjustment is completely unnecessary.
しかもその調整が簡単であるから、端末の移動に十分対
処することができ、実用上絶大なる効果が奏せられる。Moreover, since the adjustment is simple, it can sufficiently cope with the movement of the terminal, and has a great practical effect.
以下、図面を参照して本発明の一実施例につき説明する

１に光送信機１２および光受信機１３を内蔵している。This transmitting/receiving device is connected to a terminal 5 installed on the floor and performs data communication by spatial propagation with a transmitting/receiving device fixed to the ceiling or the like of the room where the terminal 5 is installed. However, this transmitting/receiving device performs data communication using, for example, infrared light as a propagation medium, and the device main body 1
1 contains an optical transmitter 12 and an optical receiver 13.
この光送信機１２および光受信機１３は指向角θ２で共

定されるようになっている。The optical transmitter 12 and the optical receiver 13 are incorporated into the device main body 11 so that they are both directed in the same direction at a directivity angle θ2. The device main body 11 is mounted on a base 14 via a universal joint mechanism 15, and can be oriented in any direction.
また、上記装置本体１１には、本装置の特徴とする光源

軸方向に指向する如く定められている。Further, the device main body 11 is provided with a light source 16, which is a feature of this device. This light component 16 emits visible light with a predetermined spread of υ angle θ3 by turning on a switch 17 provided on the top surface of the device main body 11, for example, from a semiconductor laser element that emits a visible light laser or a flashlight. It consists of a light source device, etc. The visible light emitted by the light source 16 is set to be narrower than the spread of the transmitted and received light in the relationship (θ2>θ3), and is directed in the same optical axis direction as the transmitted and received light.
