Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric float containing a battery and a light emitting body such as a light emitting diode.

[0002]

2. Description of the Related Art Conventionally, as an electric float for night fishing, a light emitting diode such as a light emitting diode is provided in the upper part of a float body, and the light emitter is provided by a battery built in the float body. It was common to light it to inform the position of the float. However, according to this, although it was possible to confirm the position of the float, it was not easy to confirm that the fish was present.

Further, as a means for notifying a fish-batch by a light-emitting body, there has been one using a total reflection prism as is known in Japanese Patent Publication No. 58-35051. In this, a total reflection prism is provided at the upper end of the float body, and the light from the light emitting element is usually reflected by the total reflection prism and received by the light receiving element, and the visible light source is turned on. When there is a fish spread and the total reflection prism is submerged in water, the light from the light emitting element is not reflected by the total reflection prism but passes through it and escapes into the water, so the light receiving element is turned off and the visible light source is turned off. To inform Uoshin.

[0004]

However, this has the following problems. The optical axes of the light emitting element and the light receiving element and the reflecting surface of the total reflection prism must be accurately aligned, which makes it difficult to set their positions. When the total reflection prism is damaged by water and the reflected light does not enter the light receiving element, the visible light source is turned off to notify the fishnet. After it gets wet, even if the total reflection prism does not submerge in water, the attached water impairs the reflectivity of the total reflection prism (light is scattered) and the operation of the light receiving element becomes unstable. It is conceivable that the visible light source goes out without it. When the float floats on the surface of the water, the float falls sideways until it receives gravity from the weight, but if the total reflection prism is once submerged in the water, the visible light source may not turn on even after the float rises.

It is a first object of the present invention to provide an electric float which can accurately detect the presence of a fish-belt and notify the fisherman in an easy-to-understand manner by lighting or blinking a light-emitting body.

A second object of the present invention is to provide an electric float that can inform a fisherman of the presence of a fish signal by radio transmission.

A third object of the present invention is to electrically notify the presence of a fish-batch by lighting or blinking a light-emitting body, and also by notifying the position of the float by lighting another light-emitting body. To provide a float.

[0008]

In order to achieve the above-mentioned first object, an electric float according to the present invention is provided with a pair of conductive parts which are electrically conducted by liquid at predetermined locations on the outer surface of a float body.
Further, a battery, a fish credit light emitter, and a fish credit light emitter drive circuit for operating the fish credit light emitter to turn on or blink by using the battery as a power source are provided in the body of the float. .

Further, in order to achieve the second object, a small radio transmitter which oscillates by using a battery as a power source to generate a radio wave when the pair of conductive parts is electrically connected is built in the float body.

Further, in order to achieve the third object, in addition to the fish credit luminous body and its drive circuit, in the body of the float,
A position display light emitter and a position display light emitter drive circuit that lights and operates the position display light emitter using a battery as a power source when the pair of conductive parts are in a non-conductive state, and turns off the light when the pair of conductive parts is conductive. It is provided.

[0011]

When the main body of the float stands upright on the surface of the water, both or one of the pair of conductive parts is positioned above the surface of the water. It is off and the fish credit illuminator is off. When the body of the float is pulled down by the fish shin and the pair of conducting parts are submerged in water to conduct electricity, the fish credit light emitter drive circuit is turned on and the fish credit light emitter is turned on or blinks.

When a small radio transmitter is built in the float body, a fisherman may carry a radio receiver with a buzzer, for example, so that the float body does not necessarily need to be monitored.
The buzzer sound can be used to confirm that there was a fishery.

When the position indicator light emitter is provided in addition to the fish credit light emitter in the float body, the position indicator light emitter is turned on when the float body is standing on the water surface. The illuminator can be turned off, and when there is a fish meal, the fish credit illuminator can be turned on or blinked to turn off the position indicating illuminator.
