【考案の詳細な説明】 本考案は夜釣りに最適な電気浮子に関するものである。[Detailed explanation of the idea] The present invention relates to an electric float that is ideal for night fishing.
夜釣りにおける代表的な対象魚としては黒鯛があるが、
この魚は光に対する警戒心が強いため、これらの魚釣り

人が魚のあたりを明確に認知できるように、浮子が水中
に沈み込んだ時に光源を消灯させたり、点滅させたり、
あるいは変色させたりするようにしたものが種々提案さ
れている。Black sea bream is a typical target fish for night fishing.
These fish are very wary of light, so when fishing for these fish, you can turn off the light source when the float sinks into the water to prevent other fish gathered by the bait from escaping. There are electric floats on the market that are designed to turn off the light underwater.1 Also, in general night fishing, the light source turns off or flashes when the float sinks into the water, so that anglers can clearly see the area around the fish. or
Alternatively, various methods have been proposed that change color.
このように光源を消灯、点滅、変色させる方法として、
従来は魚のあたりによる引張り力で浮子内部の光源スイ
ッチを動作させる機械的な方法、あるいは魚のあたりに
よって浮子が水中に沈み込んだ時に、浮子の表面に露出
させた電極に、水や海水を導体として電流を流しかつ半
導体回路により光源を制御する電気的な方法を採用して
いた。In this way, the light source can be turned off, blinked, or changed color.
Conventionally, there has been a mechanical method in which a light source switch inside the float is operated by the pulling force caused by a fish, or when the float sinks into the water due to a fish, water or seawater is used as a conductor to connect electrodes exposed on the surface of the float. An electrical method was used in which the light source was controlled by a semiconductor circuit and a current was passed through it.
しかしながら、これらの方法は次のような欠点を有して
いた。However, these methods had the following drawbacks.
まず前者の機械的な方法はスイッチの動作圧と浮子の浮
力の関係から微妙なスイッチの感度調節が必要であり、
動作が不確実である。First, the former mechanical method requires delicate adjustment of the sensitivity of the switch due to the relationship between the operating pressure of the switch and the buoyancy of the float.
Operation is uncertain.
また後者の電気的な方法は電極が海水等に触れるため、
錆の発生が問題となる。In addition, the latter electrical method has electrodes that come into contact with seawater, etc.
Rust formation becomes a problem.
さらに前記した2つの方法ともスイッチ操作のための部
品を浮子本体の内部から外部へ出したり、あるいは合成
樹脂製の浮子本体に金属の電極を露出させたりしなげれ
ばならず、その結果、防水に難点を有するものであった
。Furthermore, in both of the above methods, parts for switch operation must be brought out from inside the float body, or metal electrodes must be exposed on the float body made of synthetic resin, resulting in waterproofing. It had some drawbacks.
本考案は、プリズムによる光の屈折、反射の原理を利用

形成している。Reference numeral 11 denotes a semiconductor control circuit, to which lead wires of the visible light source 5, light emitting element 9, and light emitting element 10 are connected, and a holding section 13 for holding a power battery 12 is provided below the semiconductor control circuit 11. A power supply battery 12 is provided to form an electric circuit with the power supply battery 12.
第2図は電気回路を示したもので、前記半導体制御回路
11は2個の抵抗R1,R2と、2個のトランジスタ’
l’r 1. Tr 2 を有している。FIG. 2 shows an electric circuit, and the semiconductor control circuit 11 includes two resistors R1 and R2 and two transistors.
l'r 1. It has Tr 2 .
その接続関係は、抵抗R1と発光素子9とを直列に接続

上記構成に6いて動作を説明する。The operation of the above configuration will be explained.
まず浮子が大気中の陸上にある時の動作状態を説明する
と、発光素子9には抵抗R1を通じて電流が電源電池1
2より流れて、発光素子9は常時発光している。First, to explain the operating state when the float is on land in the atmosphere, current flows through the light emitting element 9 through the resistor R1 to the power source battery 1.
2, the light emitting element 9 constantly emits light.
そしてこの光は発光素子9の直下にあるプリズムT内を
第1図の実線の矢印で示すように直進し、プリズム7の
一方の反射面7aに当たる。This light then travels straight through the prism T located directly below the light emitting element 9 as shown by the solid arrow in FIG. 1, and hits one reflective surface 7a of the prism 7.
ここでプリズムTを直角プリズムとすると\一方の反射
面7aは入射光に対し45度の角度となる。Here, if the prism T is a right-angle prism, one of the reflecting surfaces 7a forms an angle of 45 degrees with respect to the incident light.
この一方の反射面raの外表面側は大気中であるため、
光の屈折、反射の原理から光は全反射合れるもので、一
方の反射面7aで90度の角度で反射されて他方の反射
面1bに当たり、そしてこの他方の反射面7bで一方の
反射面7aと同様90度の角度で反射され、かつそのま
まプリズム7内を透過し受光素子10で受光される。Since the outer surface side of this one reflecting surface ra is in the atmosphere,
Due to the principle of refraction and reflection of light, light undergoes total internal reflection; it is reflected at an angle of 90 degrees from one reflective surface 7a and hits the other reflective surface 1b, and then from this other reflective surface 7b, it is reflected by one reflective surface. Similar to 7a, the light is reflected at an angle of 90 degrees, passes through the prism 7 as it is, and is received by the light receiving element 10.
受光素子10はホトトランジスタ等により構成されてお
り、受光するとオンとなるため、初段のNPN)ランジ
スタ’l” r 1はオフとなる。The light-receiving element 10 is constituted by a phototransistor, etc., and turns on when it receives light, so that the first-stage NPN transistor 'l''r1 turns off.
これにより次段のNPN)ランジスタTr1もオフとな
る。As a result, the next stage NPN) transistor Tr1 is also turned off.
したがって発光ダイ万一ドからなる可視光源5は消灯し
ている。Therefore, the visible light source 5 consisting of a light emitting diode is turned off.
次に浮子を水面に投下して浮かべた場合の動作状態を説
明する。Next, the operating state when the float is dropped onto the water surface and floated will be explained.
発光素子9から出た光は第1図に示すようにプリズム1
内を直進し一方の反射面7aに到達する。The light emitted from the light emitting element 9 passes through the prism 1 as shown in FIG.
It goes straight inside and reaches one of the reflective surfaces 7a.
この場合、一方の反射面7aの外表面は下ケース3の孔
8a、8bより侵入した水または海水と接しているため
、プリズム7と水との屈折率に差がなくなり、光は第1
図の点線矢印で示すように、そのまま一方の反射面7a
を通過して水中に逃げてしまう。In this case, since the outer surface of one reflective surface 7a is in contact with the water or seawater that has entered through the holes 8a and 8b of the lower case 3, there is no difference in the refractive index between the prism 7 and the water, and the light is transmitted to the first
As shown by the dotted arrow in the figure, one of the reflecting surfaces 7a remains as it is.
It passes through and escapes into the water.
その結果、ホトトランジスタよりなる受光素子10には
光が入らないため、受光素子10はオフとなる。As a result, no light enters the light receiving element 10 made of a phototransistor, so the light receiving element 10 is turned off.
これにより、初段のNPN)ランジスタTr1はオンに
なるとともに、次段のNPN トランジスタTr2もオ
ンとなる。As a result, the first-stage NPN transistor Tr1 is turned on, and the next-stage NPN transistor Tr2 is also turned on.
したがって発光ダイオードからなる可視光源5は点灯す
る。Therefore, the visible light source 5 consisting of a light emitting diode is turned on.
このように浮子が大気中の陸上において釣り仕掛けや針
に餌をつげている時は可視光源5は消灯しており、そし
て浮子を水面に投下して浮がべろと、可視光源5は点灯
するものであるため、電源電池12の無駄な消費をなく
す、つまり電源電池12の節約を期すことができる。In this way, when the float is on land in the atmosphere and bait is attached to a fishing tackle or hook, the visible light source 5 is off, and when the float is dropped onto the water surface and floats, the visible light source 5 turns on. Therefore, it is possible to eliminate wasteful consumption of the power source battery 12, that is, to save the power source battery 12.
また可視光源5を水中で点灯させる方法は、集魚の役目
をする水中発光おもりや発光イカ針に応用すれば最適と
なるものである。Furthermore, the method of lighting up the visible light source 5 underwater will be optimal if applied to an underwater light-emitting weight or a light-emitting squid needle that serves to attract fish.
以上のように本考案によれば、プリズムによる光の屈折

子とほとんど変らない形状に形成できるとともに、防水
が確実となるものである。As described above, according to the present invention, one light source is turned on and one is turned off by an optical detection means that utilizes the principle of refraction and reflection of light by a prism. It is no longer necessary to expose metal electrodes from the inside of the float body to the outside, or to expose metal electrodes on the pole or synthetic resin float body.As a result, the float can be formed into a shape that is almost the same as a conventional float, and is guaranteed to be waterproof. It is what it is.
また半導体制御回路はへ受光素子を検知部として大気中
において光源を消灯させ、かつ浮子の水面への投下時に
光源を点灯させるように構成しているため、電源電池の
無駄な消費をなくすることができるという実用的効果も
奏するものである。In addition, the semiconductor control circuit is configured to turn off the light source in the atmosphere using the light-receiving element as a detection part, and turn on the light source when the float is dropped onto the water surface, thereby eliminating wasteful consumption of power batteries. It also has the practical effect of being able to.
