しない。Ｂより入射した光はB1とＡに出力しA1
には出力しない。又、互いの光は干渉することが
ない。 First, the principle will be explained with reference to FIGS. 1 and 2. FIG. 1 shows a directional coupler. This is a structure in which optical fibers are bent at a predetermined radius of curvature, a portion of which is polished, and then butted together. The light incident from A is branched at C and output to A1 and B, but not to B1 . The light incident from B is output to B 1 and A and A 1
It is not output to. Also, the lights do not interfere with each other.

射、無反射を判別できる。 FIG. 2 shows an explanation of the principle of constructing a switch using this directional coupler. 1 is an optical fiber, 2 is a directional coupler, 3 is a light emitting element attached to one end of the main trunk of optical fiber 1, 4 is a light emitting circuit for making this light emitting element 3 emit light, 5 is a trunk of optical fiber 1 A light-receiving element attached to one end; 6 a light-receiving circuit including a switch circuit operated by the output of the light-receiving element 5; 7 a reflection mechanism disposed opposite the other end of the optical fiber 1; It consists of a completely reflective surface 7a and a non-reflective surface 7b. This is because when the light from the light emitting element 3 reaches the other end of the optical fiber 1, if there is a perfect reflection surface 7a there, it is reflected and reaches the light receiving element 5 via the directional coupler 2. On the other hand, when there is a non-reflective surface 7b, the light is transmitted to the light receiving element 5.
It does not reach. In this way, the light receiving circuit can determine whether light is reflected or not.

ンジスタ、１５はランプである。 The circuit configuration will be explained with reference to FIG. 3, where 8 is a power supply, 9 is a first variable resistor, 10 is a first differential amplifier circuit, and 11 is a negative feedback resistor. The light receiving element 5 is connected between the input terminals of the first differential amplifier circuit 10. A movable terminal of the first variable resistor 9 is connected to one input terminal of the first differential amplifier circuit 10. A second differential amplifier circuit 12 is connected downstream of the first differential amplifier circuit 10 . A second variable resistor 13 is connected to one input terminal of the second differential amplifier circuit 12 so that a desired voltage is applied. 14 is a transistor, and 15 is a lamp.

しない。 This sets the terminal, which is one input terminal of the first differential amplifier circuit 10, to a predetermined voltage V1 using the first variable resistor 9. When the light receiving element 5 receives light, the leakage current changes, and this change is amplified at a ratio corresponding to the resistance value of the negative feedback resistor 11 and appears at the output of the first differential amplifier circuit 10 as V 1 +△V. . The voltage at the terminal is adjusted by the second variable resistor 13 so that the output voltage of the second differential amplifier circuit 12 changes from a value close to the power supply voltage to a voltage close to zero by this voltage change △V. Set it. Therefore, when the light receiving element 9 receives light, the transistor 14 is turned on and the lamp 15 is turned on, and when no light is received, the transistor 14 is turned off and the lamp 15 is not turned on.

ーである。 FIG. 4 shows the inside of the timer setting section. A plunger 17 made of a substance attracted by a magnet is arranged in a cylinder 16. A mirror surface 18 is attached to one end of the plunger 17. One end of the optical fiber 1 is guided into the cylinder 16 and is opposed to the mirror surface 18 . A viscous substance having a predetermined viscosity is housed within the cylinder 16 . 19 is a stopper for the plunger 17.

When the plunger 17 is located at the right end of
As shown by the chain line, the N and S poles move toward the opposing right end and remain stationary. Even if the plunger 17 moves too far to the right due to some kind of shock when it is in this rest position, the S pole comrades will repel the force and return to the original rest position again to remain stable.
次に、上述した本発明の一実施例についてその

受光素子５で受光される光は少なく第３図のトラ
ンジスタ１４はオンとならない。 In a steady state in which the magnet 20 is located at the right end of the cylinder 16, the plunger 17 is located to the right of the cylinder 16, and the distance between the end of the optical fiber 1 and the mirror surface 18 is large. The light from the light emitting element 3 is transmitted to the optical fiber 1. Therefore, the light from the end of the optical fiber 1 is diverged, reflected by the mirror surface 18, and the amount of reflected light that enters the optical fiber 1 from the end is small. Therefore, the amount of light received by the light receiving element 5 is small and the transistor 14 shown in FIG. 3 is not turned on.

燈するタイマー機能が得られる。 Then, the magnet 20 is positioned at the left end position indicated by the chain line in FIG. At that time, the plunger 17 is sucked to move to the left, but the cylinder 1
The viscous substance within 6 moves it over a predetermined period of time. When this movement is completed, the plunger 17
is located at the left end and stops. At this position, the mirror surface 18 comes into contact with the end of the optical fiber 1. Therefore, the light is totally reflected by the mirror surface 18, enters the optical fiber 1 again, and reaches the light receiving element 5 via the directional coupler 2. When the light receiving element 5 receives this light, the first,
Amplification is detected by the second differential amplifier circuits 10 and 12, the transistor 14 is turned on, and the lamp 15
is lit. This provides a timer function in which the lamp 15 turns on after a predetermined period of time after the magnet 20 is moved from the right end to the left end.
