[0002]

2. Description of the Related Art Conventionally, fishing lines used for fishing have been
It is sufficient to inform the fisherman that the fish has been caught by a change in tension and the movement of the thread, and to have the mechanical strength functions of withstanding the pulling of the fishing fish, pulling the fish up, and lifting up. It has been considered, and in such demand,
Only thin and strong threads were developed and improved.

However, since fishing is a method in which a fishing line is stretched between the hook side where a fish is likely to be present and a fisherman, and a fisherman catches a fish with a signal of the fisherman as a clue, the fisherman has more information about the fisherman. If information can be obtained, it is possible to increase fishing results and further increase interest in fishing.

On the other hand, in recent years, an optical fiber for optical transmission has been developed and is widely used mainly for communication. The optical fiber is used as a fishing line to convert useful information into an optical signal, and the optical fiber is used. If the information is transmitted through the inside, detailed information can be obtained, and the fishing technique should be further advanced. The present invention is
It provides such a fishing method, and in the history of fishing,
Expected to be revolutionary, the present invention
It is possible to open up all the possibilities for an increasingly interesting fishing method.

As described above, fishing lines have conventionally been required to have only mechanical strength, and have been improved to have a high breaking strength, a large breaking elongation, a supple and thin shape. Also in optical fiber,
Although it has a short history of about 20 years since its practical application, it can be said that mechanical strength as a fishing line has been sufficiently provided because of the remarkable increase in strength in recent years. Therefore, if an optical fiber is used as a fishing line, a new function of optical signal transmission can be added to the fishing world in addition to mechanical strength. Optical fibers include silica-based fibers, multi-component glass-based fibers, plastic-based fibers, etc., but due to recent advances in coating technology, both breaking strength and breaking elongation have significantly increased. It can be used.

1 is a schematic configuration diagram for explaining a first embodiment of a fishing method according to the present invention together with a fishing apparatus. In the drawing, 1 is a yarn, 2 is a light emitting device, 3 is Harris, 4 is fishing hook, 5 bait, 6 is tackle, 7 is a rod, 7a is a thread guide, 7b is a guide wheel, 8 is a reel, 8a is a spool, 9 is a fish.

The yarn 1 is provided with an optical fiber. The light emitting device 2 is tied to the tip of the thread 1 on the side which is fed from the spool 8a of the reel 8 and enters the water. At the tip of the light emitting device 2, a device 6
Are tied together. The device 6 shown in the figure is Harris 3,
This is the simplest example consisting of a hook 4 and a bait 5,
Any suitable device may be attached to the target fish.

The light emitting device 2 is a light emitting element such as LE.
It has D, and the light emitting state is changed according to slight distortion and movement. For this purpose, a micro battery is installed if necessary, and a switch for turning on / off by a slight deformation or change in tension is installed in the power circuit, and the device 6 is pulled to turn the switch on or off to turn on or off the light emitting element. Turn it off. The electric resistance may be changed by changing the tension, and the electric resistance may be incorporated in the light emitting circuit to change the light emission amount in an analog manner. The light emitted from the light emitting device 2 is small in attenuation during optical fiber transmission even if it is a weak optical signal, and can be captured even by a minute light amount change by the highly sensitive light receiving element. Further, as another example of the light emitting device 2, a piezoelectric element may be used to convert strain into an electric signal and drive the light emitting element to generate an optical signal. In this case, the power supply can be omitted. As described above, according to the recent technology, the light emitting device 2 can easily realize devices having all functions.

While the fish 9 bites the bait 5 and then hooks on the fishhook 4, the light emitting device 2 is swung by the fish 9 and therefore undergoes various deformations and distortions. The light emitting state of the light emitting device 2 changes according to this deformation or distortion, and the optical signal from the light emitting device 2 is transmitted through the optical fiber of the path yarn 1 and reaches the angler side. Since the end of the road thread 1 is fixed to the spool 8a of the spinning reel 8, it is very easy to attach a light receiving element to this end to capture light and convert it into an electric signal. An angler can be made to recognize the relationship between the fish 9 and the tackle 6 by providing an actuator that makes a sound or vibrates the spinning reel 8 or the rod 7 in response to the detected electric signal.

According to the conventional fishing method, when the tackle is thrown away and the line is extended for a long time, the mechanical fish-belt is not transmitted because it is attenuated in the water. Since a fish signal is transmitted as an optical signal to a hand and is converted into a signal that can be easily recognized by a fisherman and the fisherman can be notified of it, an accurate and detailed fish carrier can be obtained even from a distant device. By learning what kind of signal the fish catches the needle, the fisherman can skillfully determine the "matching", that is, the timing of starting the reel winding with the rod.

Further, there is a possibility that it is possible to identify the difference in the signals that appear depending on the type of fish, not only improving the fishing results, but
You can also enjoy the gameplay of hitting the expectations. The game nature, which is an element of fishing enjoyment, is not impaired by the present invention, but rather the variety of game nature is enriched.

In this embodiment, a spinning reel is used as the reel 8. In the spinning reel, since the spool 8a does not rotate, the end of the optical fiber wound around the spool 8a does not move and does not rotate. Therefore, it is easy to directly connect the end of the optical fiber to the light receiving element and house them in the housing of the spinning reel 8 including the signal converter at the subsequent stage.

Even if a single-axis reel or a twin-axis reel in which the spool itself rotates is used, if an optical fiber end is arranged at the center of the rotation axis, an optical signal is sent to a light receiving element provided close to that position. Since it can be guided, a configuration similar to that of the spinning reel can be implemented. Further, in the case of boat fishing, hand fishing may be performed without using the reel.

"Matching" is appropriate, and it is easy to worry that the optical fiber will be damaged because the line 1 bends sharply at the tip of the rod 7 until the fish caught by the needle is pulled up and caught. In fact, as the tension of the line thread 1 increases, the line thread 1 takes the shortest curve that balances the rigidity of the rod 7, so that the tip of the rod 7 draws a smooth curve and the optical fiber of the line thread 1 bends. Is almost never damaged. However, in some cases, it may be effective to provide a guide wheel 7b shown by a dotted line in FIG. 1 at the tip of the rod 7 or to reduce the interval between the ring-shaped thread guides 7a. It is also effective to use the "middle threading type" in which the thread 1 is passed through the rod 7.

FIG. 2 is a schematic configuration diagram of a main part for explaining a second embodiment of the fishing method according to the present invention together with a fishing device. In the figure, the same parts as those in FIG. Reference numeral 10 is a top bin, 11 is a weight, 12 is a power supply battery, and 13 is a power supply lead wire.

In a top bin type device using the top bin 10, a power source battery 12 for the light emitting element of the light emitting device 2 is built in the weight 11 and power is supplied to the light emitting device 2 by a power supply lead wire 13. Power battery 1 for weight 11
When 2 is built in, a relatively large battery can be used. Of course, the power supply battery may be built in the light emitting device 2 as shown in FIG.

In the first and second embodiments, the fish show an interest in food, and the deformation and distortion of the light-emitting device portion resulting from a series of motions of sticking and biting it are converted into an optical signal, and the optical fiber is used. Is transmitted to the angler side, and converted to a shape that can be easily recognized by the angler side to obtain fish-string information. The light emission may be on or off, or the amount of light emission may be changed by changing the electric resistance. In addition, the analog amount may be changed.

Since the latest optoelectronics does not miss the slight change in light and allows the person to recognize it by enlarging the change, it is possible to obtain sufficient fish information from delicate to rough ones. You can tell the angler.

The third embodiment is another example in which an optical signal is detected as a change in analog amount, and the main part is shown in FIG. In the figure, those parts that are the same as those corresponding parts in FIG. 1 are designated by the same reference numerals, and a description thereof will be omitted. 14 is a meandering part.

In this embodiment, a meandering portion 14 is formed by shrinking a part of the path 1 near the end on the fishing hook side. The meandering portion 14 is contracted when no tension is applied, and when tension is applied, the meandering portion 14 tends to become straight according to the tension. When the applied tension is released, it returns to a contracted state. The light emitting device 2 does not turn on / off, and continuously emits an optical signal in a continuously constant light emitting state, a light emitting state in which an intermittent state is continuous, or the like.
Since the optical signal transmitted through the meandering portion 14 has a large amount of leaked light, it is not transmitted or is slightly transmitted to the angler side.

In FIG. 3A, the fish is not eating,
As shown in FIG. 3 (B), when the fish 9 bites, the tension applied to the path yarn 1 increases, the crimped state of the meandering portion 14 becomes loose, and the leak light at the meandering portion 14 decreases, The amount of light transmitted to the angler increases. There is also a moment when the tension is reduced even after the fish is caught, and in this case, the contraction of the meandering portion 14 is restored and the amount of transmitted light is reduced. On the fisherman side, such a change amount of light is taken out from the reel to the outside,
It can be fishery information. It is also possible to record and record the change pattern on a recorder, or to guide it to a computer for recording, analysis and research.

FIG. 4 is a schematic configuration diagram of a main part for explaining a fourth embodiment of the fishing method according to the present invention together with a fishing device. In the figure, the same parts as those in FIGS. 1 and 2 are designated by the same reference numerals and the description thereof will be omitted.

In the third embodiment, the optical fiber is bent, and the fish is pulled to extend the bending. However, in this embodiment, the fish is drawn with respect to the unbent optical fiber. It is designed to give a bend. To the light emitting device 2, the yarn 1 having an optical fiber is attached through the ring at the upper end of the top bin 10, and the lower end of the top bin 10 is attached. The weight 11 is attached to the light emitting device 2 directly or at a short interval.

In FIG. 4A, no fish are eating. In this state, the bending is not applied to the road yarn 1,
The emitted light from the light emitting device 2 is transmitted to the angler side by the optical fiber of the line thread 1. As shown in FIG. 4 (B), when the fish 9 bites, the path line 1 is bent, leak light increases, and the amount of light transmitted to the angler side decreases. By detecting such an amount of change in light on the angler side, the third
It is also possible to recognize a fish pattern and record it by changing patterns drawn on a recorder, or to guide it to a computer to record it for analysis and research as in the case of the above embodiment.

The above-described method of converting the fishnet into an optical signal and transmitting it through an optical fiber to extract it can be directly applied to fishing using pseudo food such as lure fishing and fly fishing. Fishing without using reels includes, for example, hebruna fishing and mountain stream fishing. In these cases, too, light was released to the outside by tying a light emitting device, etc., with a line thread having an optical fiber. The light may be detected visually by the angler's eyes. In this case, the light transmitted through the optical fiber must be light in the visible range.

FIG. 5 is a schematic configuration diagram for explaining a fifth embodiment of the fishing method of the present invention together with a fishing apparatus, in which an optical signal transmitted through an optical fiber is visually detected. This is an example. In the figure, the same parts as those in FIG. 1a and 1b are yarns, 15
Is a luminous ball.

This embodiment is an example suitable for mountain stream fishing. The yarn 1a has an optical fiber, and the yarn 1b does not need to have an optical fiber. The light emitting device 2 is attached to the fishing hook side of the road thread 1a, and the light emitting ball 15 is attached to the opposite side.
Is attached, and the yarn 1b is tied to the light emitting ball 15. The road thread 1b is tied to the tip of the rod 7. The light emitted from the light emitting device 2 is transmitted through the optical fiber of the relatively short path yarn 1a in accordance with the fish pattern, is released to the external space as light at the light emitting ball 15 in the air, and is visually recognized. It The fisherman can see the light emitting ball 15 and add information on how the light is emitted along with how the light is emitted in the same manner as when fishing by looking at the conventional landmarks, and the situation can be determined, making it easier to hit. The light-emitting ball 15 may diffuse the light transmitted by the optical fiber. For example, a spherical glass ball is used, and the light from the optical fiber is made incident and diffused.

FIG. 6 is a schematic configuration diagram for explaining a sixth embodiment of the fishing method of the present invention together with a fishing apparatus, in which an optical signal transmitted through an optical fiber is visually detected. It is another example. In the figure, the same parts as those in FIG. 1 and FIG. 16 is Uki.

This embodiment is an example suitable for the fishing of the hellebuna. Also in this example, the optical fiber of the path yarn 1a connects the light emitting device 2 and the light emitting ball 15, and the position of the hollow 16 between the light emitting device 2 and the light emitting ball 15 can be adjusted by the rubber tube on the path yarn 1a. It is locked. The fisherman will judge the condition of the fish by superimposing two pieces of information, that is, the movement of the bow 16 and the light emitting state of the light emitting ball 15. Uki 13 and luminous ball 1
Since it is close to 5, the two can be easily observed at the same time.

In the above-mentioned embodiment, it was explained that the information of the fish communication is transmitted by the optical fiber, but the present invention is
Information other than Uoshinobu can be transmitted to be useful for fishing.

As seen in recent CCD cameras, ultra-compact video cameras have appeared, and if this video signal is used as an optical signal and transmitted through an optical fiber, it is possible to fish while watching the condition of the fishing fish. Become.

FIG. 7 is a schematic block diagram for explaining a seventh embodiment of the fishing method of the present invention together with a fishing device, and is an example of an embodiment using a video camera. In the figure, the same parts as those in FIG. Reference numeral 17 is a micro video camera, 18 is a monitor display, and 19 is a protective tube.

The micro video camera 17 has a built-in power supply battery and outputs a video signal as an optical signal. This optical signal is transmitted by the optical fiber of the path yarn 1, taken out to the outside through the fiber end of the reel 8, and the monitor display 18
To play the image. By setting the orientation of the tackle so that the entire tackle 6 falls within the shooting range of the micro video camera 17, the relationship of the fish to the tackle can be constantly monitored and the hit can be made while watching. Although the micro video camera 17 is very small, it is heavy as an element for fishing, and thus it also plays a role like a weight in a tackle bin. Therefore, the road yarn 1 around the branch point where the tackle 6 is attached is
It is also effective to cover the protective tube with the micro video camera 17 by integrating them with.
