号８，点灯信号９，点灯信号１０が入力され、それらの
信号により各発光部１〜３が点灯する。なお、このと
き、各発光部１〜３が同時に点灯しないようにする。FIG. 1 is a block diagram showing an embodiment of the present invention. A lighting signal 8, a lighting signal 9, and a lighting signal 10 are input to the light emitting unit 1, the light emitting unit 2, and the light emitting unit 3, respectively, and the respective light emitting units 1 to 3 are turned on by these signals. At this time, the light emitting units 1 to 3 are prevented from lighting at the same time.
【０００７】各発光部１〜３からの光は受光部４によっ
て検知される。受光部４からの出力はアンプ部１５によ
って増幅され、フリップフロップ５，６，７のそれぞれ
のデータ入力端子に入力される。Light from each of the light emitting units 1 to 3 is detected by the light receiving unit 4. The output from the light receiving section 4 is amplified by the amplifier section 15 and input to the respective data input terminals of the flip-flops 5, 6, 7.
【０００８】また、点灯信号８はフリップフロップ５の
クロック端子に、点灯信号９はフリップフロップ６のク
ロック端子に、点灯信号１０はフリップフロップ７のク
ロック端子に入力されることにより、出力信号１１には
発光部１からの受光情報が、出力信号１２には発光部２
からの受光情報が、出力信号１３には発光部３からの受
光情報がそれぞれ出力する。Further, the lighting signal 8 is input to the clock terminal of the flip-flop 5, the lighting signal 9 is input to the clock terminal of the flip-flop 6, and the lighting signal 10 is input to the clock terminal of the flip-flop 7, so that the output signal 11 is output. Is the received light information from the light emitting unit 1, and the output signal 12 is the light emitting unit 2
The light reception information from the light emitting unit 3 is output to the output signal 13 as the light reception information from the light receiving unit.
【０００９】そのため、媒体１４が発光部１からの出力
光を遮った場合は、出力信号１１がハイからロウに、発
光部２からの出力光を遮った場合は、出力信号１２がハ
イからロウに、発光部３からの出力光を遮った場合は、
出力信号１３がハイからロウに変化する。Therefore, when the medium 14 blocks the output light from the light emitting section 1, the output signal 11 changes from high to low, and when the medium 14 blocks the output light from the light emitting section 2, the output signal 12 changes from high to low. When the output light from the light emitting unit 3 is blocked,
The output signal 13 changes from high to low.
【００１０】このようにして出力信号１１，１２，１３
を監視することにより、媒体１４の有無検知を行なう。In this way, the output signals 11, 12, 13
The presence or absence of the medium 14 is detected by monitoring.

【発明の効果】以上説明したように、本発明は、媒体検
知における発光部を１つにしたので、受光素子の削減，
検出回路の削減，ケーブル類の削減ができるという効果
を奏する。As described above, according to the present invention, since the number of light emitting portions in the medium detection is one, the number of light receiving elements can be reduced.
This has the effect of reducing the number of detection circuits and cables.
