The structure of Publication No. 57-54051 is disclosed. As shown in Figure 1, this measures the speed of the vehicle by converting the rotor 2 into angular movement using the eddy current action generated by the rotational movement of the magnet 1. If the speed is less than a set value, the rotor The shielding plate 3 attached to the shield plate 2 is not interposed in the gap 6 between the light emitting element 4 and the light receiving element 5 which are arranged opposite to each other. However, when the speed exceeds a set value, the shielding plate 3 intervenes in the gap 6 and blocks the irradiated light from the light emitting element 4 to the light receiving element 5, and the electric circuit 7 is activated to light the lamp 8.

is a light emitting diode which is a light emitting element in Fig. 1,
Q 1 is also a phototransistor which is a light receiving element,
8 is an indicator lamp for warning. The phototransistor Q1 is turned on or off depending on whether a shielding plate 6, which is a control member for controlling optical coupling, is interposed in the gap 6 between the light emitting diode D1 and the phototransistor Q1 . The lamp 8 is connected to a power source E, and is also connected in series with a first resistor R1 and a light emitting diode D1 to form a closed circuit. Further, a series circuit of a resistor R 1 and a light emitting diode D 1 , a series circuit of a second resistor R 3 and a chargeable/dischargeable electrolytic capacitor C are connected in parallel, and this capacitor C, a resistor R 2 and a photodiode are connected in parallel. A series circuit of transistors Q 1 is connected in parallel. 9 is a transistor circuit operated by the voltage between the terminals of the capacitor C, which includes an emitter resistor R 4 , a transistor Tr 1 , predetermined bias resistors R 5 , R 6 , R 7 , and Darlington-connected transistors Tr 2 and Tr 3 and stabilizing diodes
Consists of D 2 . One end of the emitter resistor R 4 in the transistor circuit 9 is connected to the connection point between the resistor R 3 and the capacitor C, and the resistor R 6 and the collector of the transistor Tr 3 are connected to the power source E via the lamp 8.
以上によつて構成される本考案の作用を説明す
る。 The operation of the present invention constructed as above will be explained.
先ず、車輌が所定速度以下で走行している場
合、遮蔽板３は空隙６に介在しないので、フオト
トランジスタQ1は受光状態にありONしているた
め、コンデサＣの端子間電圧は抵抗R2とR3の分
圧によつて決まる。ここで、抵抗R2，R3とR6，
R7の関係はR6／R7＜R3／R2に設定してある。 First, when the vehicle is running at a predetermined speed or lower, the shielding plate 3 is not interposed in the air gap 6, so the phototransistor Q1 is in the light receiving state and is turned on, so the voltage across the terminals of the capacitor C is equal to the resistor R2. and the partial pressure of R 3 . Here, the resistances R 2 , R 3 and R 6 ,
The relationship of R 7 is set to R 6 /R 7 <R 3 /R 2 .
この関係よりフオトトランジスタQ1がONの時
はトランジスタTr1のベース・エミツタ間は常に
逆バイアスとなり、トランジスタTr1はOFF、そ
のためトランジスタTr2とTr3にはベース電流が

の結果ランプ８は消灯する。尚、ランプ８を介し
て発光ダイオードD1とフオトトランジスタQ1に
駆動電流は流れるが、抵抗R1，R2，R3を充分大
きくしてあるのでランプ８は点灯するにいたらな
い。 From this relationship, when phototransistor Q 1 is ON, there is always a reverse bias between the base and emitter of transistor Tr 1 , and transistor Tr 1 is OFF, so no base current flows through transistors Tr 2 and Tr 3 , and transistor Tr 2 and Tr 3 is also turned off, and as a result, lamp 8 is turned off. Although a driving current flows through the lamp 8 to the light emitting diode D 1 and the phototransistor Q 1 , the lamp 8 does not turn on because the resistors R 1 , R 2 , and R 3 are made sufficiently large.

する。 Next, when the vehicle exceeds a predetermined speed, the shielding plate 3 is interposed in the gap 6 and blocks the radiation from the light emitting diode D1 , and the phototransistor Q1 does not receive light and is turned off. And phototransistor Q1 changes from ON to OFF.
Therefore, the capacitor C is charged via the resistor R3 , and when the voltage becomes higher than the base voltage of the transistor Tr1 , the transistor Tr1 becomes forward biased and turns on. And transistors Tr 2 and Tr 3
Base current flows and transistors Tr 2 and Tr 3 are also turned on.
While the transistor Tr 3 is ON, the current from the power source E flows through the lamp 8 to the collector of the transistor Tr 3 , and the lamp 8 lights up. Then capacitor C is discharged and its voltage is transferred to transistor
When the voltage becomes lower than the base voltage of Tr 1 , the transistor
Tr 1 becomes reverse biased and turns OFF. Therefore, no base current flows through the transistors Tr 2 and Tr 3 , and the transistors Tr 2 and Tr 3 are also turned off. and,
Power supply E flowing to the collector of transistor Tr 3
The current flows through the resistor R3 again to the capacitor C, and the capacitor C is charged. As a result, the lamp 8 is almost turned off. Thus, while capacitor C is being charged, the current from source E is R 3
While the capacitor C is being discharged, the current from the power source E flows through the collector of the transistor Tr3 to ground, so the lamp 8 is turned on. Therefore, the lamp 8 blinks at the timing of charging and discharging the capacitor C.
以上のように、車輌が所定速度を越えると、従

である。 As mentioned above, when a vehicle exceeds a certain speed, conventionally the lamp would remain on and it would be difficult for the driver to notice, but by displaying a flashing lamp, the driver will be more alert and the driver will notice immediately and reduce the speed. , the danger is reduced and the practical effect on traffic safety is great.
