また、それらを同時に動作（発光）させることがないの
で、受信側で混信を生じることも防止できる。Further, since they are not operated (emitted light) at the same time, it is possible to prevent interference from occurring on the receiving side.
〔実施例］
以下、図面を参照して、本発明の実施例について説明す
る。[Examples] Examples of the present invention will be described below with reference to the drawings.
第１は本発明を実施例を示す説明図である。送信装置に
は二個の発光器１１．１２を具えており、所定の間隔を
置いて配置されている。受信装置も二つの受光器１６．
１７を具えている。The first is an explanatory diagram showing an embodiment of the present invention. The transmitting device includes two light emitters 11, 12, which are arranged at a predetermined distance. The receiving device also has two light receivers 16.
It has 17.
二つの発光器１１．１２から異なる信号をそれぞれ受光
器１６．１７に送信する場合、受光器１６．１７が二個
の発光２Ｓｔｔ、 １２の発生する赤外線のいずれもが
到達する範囲に設置されたとき、発光器１１．１２の双
方を同時に動作させて赤外線による信号を発生させると
、受光器１６および１７では混信が生じてしまう。When transmitting different signals from the two light emitters 11.12 to the light receivers 16.17, the light receivers 16.17 are installed in a range where both of the infrared rays generated by the two light emitters 2Stt and 12 can reach. If both the light emitters 11 and 12 are operated simultaneously to generate infrared signals, interference will occur in the light receivers 16 and 17.
そこで、本発明においては、発光器１Ｌ１２を同時に動
作させるのではなく、交互に動作させる。Therefore, in the present invention, the light emitters 1L12 are not operated simultaneously, but are operated alternately.
それによって、発光器１１．１２から交互に赤外線によ
る信号が受光器１６．１７にそれぞれ伝送される。As a result, infrared signals are alternately transmitted from the emitters 11, 12 to the receivers 16, 17, respectively.
同時に二つの信号が受信されることはないので、混信は
防止できる。Since two signals are never received at the same time, interference can be prevented.
第２図は、本発明の他の実施例を示す説明図である。こ
の例では、発光部と受光部が四個ずつ配置されている。FIG. 2 is an explanatory diagram showing another embodiment of the present invention. In this example, four light emitting sections and four light receiving sections are arranged.

してしまう虞がある。Receiver 26.27.28.29 has four emitters 21.2
When installed in a range where two or more of the infrared rays generated by 2.23.24 can reach, if multiple of the emitters 21, 22, 23, and 24 are operated simultaneously to generate infrared signals, the receiver There is a risk that interference may occur on 26.27.28.29.
そこで、本発明においては、発光器２１〜２４を同時に
動作させるのではなく、順次にスキャンして動作させる
。それによって、発光器２１〜２４から順次に赤外線に
よる信号が受光器２６〜２９に伝送される。受光器２６
は発光器２１の信号を受信し、同様にそれぞれ対応する
発光器の信号を受信する。一つの受光部に同時に二つの
信号が受信されることはないので、混信は防止できる。Therefore, in the present invention, the light emitters 21 to 24 are not operated simultaneously, but are sequentially scanned and operated. Thereby, infrared signals are sequentially transmitted from the light emitters 21 to 24 to the light receivers 26 to 29. Light receiver 26
receive the signal of the light emitter 21, and similarly receive the signals of the respective light emitters. Since two signals are never received by one light receiving section at the same time, interference can be prevented.
