[0016] In the sixth aspect, the fish bill is detected by the strain sensor integrally provided on the connecting fitting or the fishing hook.

In the present invention, a strain sensor is provided at or near the fishing hook, and the strain due to fish biting is detected by the strain sensor and transmitted by a signal line. This has the effect of being able to detect a fishery without using it.

Here, the signal line is not particularly limited as long as it can transmit an electric signal, and the signal line and the fishing line may be twisted and used. If a conductive fishing line as described below is used, the signal line itself can also be used as the fishing line.

Here, the conductive fishing line is, for example, a conductor wire made of an in-situ fiber-reinforced copper alloy, and the conductor wire itself can realize a tensile strength of 980 N / mm ² or more and has high conductivity. Since it can be realized, the electric signal can be transmitted at the same time as it functions as a fishing line.

Here, the in-situ fiber-reinforced copper alloy conductor is a fiber-reinforced copper matrix, in particular:
It refers to a wire formed by forming fibers on the spot, that is, in the step of forming the wire. For example, it refers to a wire or the like containing in-situ formed fibrous chromium having a maximum diameter of 2.5 μm or less and an average diameter of 1.0 μm or less in a copper matrix.

The in-situ fiber-reinforced copper alloy conducting wire is, for example, swaged from an alloy material having a chromium content of 1 to 25% by weight and a balance of substantially copper, and then the first alloy material. By cold drawing, then solution treatment, and then second cold drawing, fibrous chromium is formed in situ in a copper matrix to obtain a wire, and at least the wire is obtained. It is obtained by forming a conductive wire using one piece. The alloy material used as the material is not limited to those described above, and for example, the chromium content is 1 to 25% by weight, the silver or zirconium content is 0.01 to 8% by weight, and the balance is substantially the same. An alloy material made of copper can also be used.

In the wire rod made of such a composite material, high conductivity can be ensured by the flow of an electric current through the copper matrix, and mechanical strength can be secured by the fiber reinforcement, so that high mechanical strength and high conductivity are conflicting with each other. It also has the property of Therefore,
It has a high tensile strength that can be used as a fishing line by itself, is excellent in characteristics such as bending resistance, and can secure high conductivity by itself.

In order to secure the characteristics as a conductive fishing line, the conductivity is 50% IACS or more, preferably 70%.
IACS or more and tensile strength of 980 N / mm ² ,
Preferably, it is necessary to use a conductor wire of 1274 N / mm ² or more. Further, the breaking elongation of such a conductive fishing line is 4
% Or less, preferably 2% or less. This is accomplished by using an in situ fiber reinforced copper alloy with high conductivity and high tensile strength.

The conductive wire included in such a conductive fishing line is
The present invention requires two systems, and each may have a single wire having a predetermined diameter, for example, a wire having a diameter of about 50 μm to 0.8 mm may be used alone, or a multi-core wire, for example,
A plurality of ultrafine wires having a diameter of about 12 to 80 μm may be collected, but it is preferable to use a multifilamentary wire in order to secure flexibility as a fishing line and reduce curls and kinks.

Further, as the structure of the conductor wire provided with the insulating coating layer, a structure in which a single wire or a multi-core wire is covered with an insulating coating,
A coaxial line may be used, and as the coaxial line, a single wire or a multi-core wire may be used at the center. In the present invention, it is preferable that two conducting wires each having an insulating coating layer are twisted and an outer coating layer is applied if necessary, or a coaxial wire structure is provided, and a structure including two lines of conducting wires is preferable.

Such a conductive fishing line has the following uses.
It has a water-resistant insulating coating layer, for example, a coating layer made of polyester resin, fluorine resin, polystyrene resin, polyvinyl chloride resin, etc., and enamel coating, etc. You can

Further, in the present invention, a fishing line may be formed by twisting a normal conductive wire as a signal line with a high-strength fishing line such as polyethylene or polyamide, without using a conductive fishing line. In this case, a normal conductor may be used as the signal wire, or among the conductors made of in-situ fiber-reinforced copper alloy,
You may use a comparatively thin thing.

On the other hand, the strain sensor used in the present invention is
It measures the change in strain as a change in resistance value. A semiconductor gauge or the like can be used.

Such a strain sensor may be provided so that strain is generated in the strain sensor when the fish is eaten by the bait attached to the fishing hook or pulled by the fish, and the method of providing the strain sensor is not particularly limited. However, for example, if a fish hook is connected between the hook and the fishing line, the hook will be elastically deformed and strain will be generated when the fish is pulled, and the strain sensor will be fixed to this hook. Good. As a result, strain is generated in the strain sensor together with the connection fitting, and the resistance value is changed. Of course, a strain sensor may be provided integrally with the connection fitting.

A strain sensor may be integrally provided on the fishing hook itself. In this case, it is possible to detect the strain that occurs when the fish just eats, and it is possible to further improve the sensitivity.

Further, the fish-fish detecting section connected to such a strain sensor by a signal line and receiving a signal includes a resistance value detection circuit for detecting a change in the resistance value of the strain sensor. The resistance value detection circuit is not particularly limited as long as it can measure the change in resistance value of the strain sensor, but generally, a Wheatstone bridge circuit may be used.

Further, the fish-spot detecting section is provided with an informing means for making a predetermined informing based on a change in the resistance value of the strain sensor detected by the resistance value detecting circuit. Here, the notification means is not particularly limited as long as it can notify that the change in the resistance value of the strain sensor is detected. For example, the fact that the change in the resistance value has become equal to or higher than a predetermined level is notified by light, sound, vibration, or the like, and the degree of the change may be notified in two stages or in three or more stages.
Also, it may be done by displaying numbers on the LED, or L
You may make it display on a screen, such as a CD, by numbers or graphs.

It should be noted that the fish-spot detecting section is equipped with a power source for driving the resistance detecting circuit and the notifying means, if necessary.

The output of the resistance detection circuit may be output to the notification means via various driver ICs. For example, the output of the resistance detection circuit may be output to the notification means via a microcomputer such as a one-chip microcomputer. Good.

Here, in the case where a microcomputer is installed, for example, analysis data obtained by classifying changes in the signal from the strain sensor for each fish species is stored in a memory, and the actually detected data and the analysis data are compared. By doing so, it is possible to predict the type of fish that is causing the fish-belt.

As shown in the figure, the fish-belt detecting device according to the present embodiment is provided with a fish-belt detecting section 10 provided in the vicinity of a grip of a fishing rod 1, and a fish-belt detecting section 10 extending from the fish-belt detecting section 10 via a reel 2 to a tip thereof. The fishing line 20 having the fishing hook 3 and the strain detecting section 30 provided near the fishing hook 3 are provided.

Here, the fish-fish detecting section 10 has a display section 11, an LED lamp 12 and a speaker 13 as an informing means, and has a fish-fish detecting circuit inside. The fish-spot detection circuit will be described later.

In the present embodiment, the fishing line 20 is a signal line 2 of two or more lines connected to the fish-fish detecting circuit of the fish-fish detecting section 10.
1 and the fishing line main body 22 are twisted together. Here, as the fishing line body 22, a commercially available thread can be used, but it is preferable to use a thread having a relatively high tensile strength such as a polyethylene thread or a polyamide thread. In addition, the signal line 21
Used a general conducting wire.

On the other hand, the strain detecting section 30 has a strain sensor 31, and in this embodiment, is fixed to a connecting fitting 32 provided between the Harris 4 holding the fishing hook 3 and the fishing line 20. That is, the connecting fitting 32 is connected to the fishing line connecting portion 32a connected to the fishing line 20 and the Harris connecting portion 32b connecting the Harris 4 via the bent portion 32c bent substantially at a right angle, and the bent portion 32c is strained. Sensor 3
1 is fixed. Further, a weight connecting portion 32d is provided at a place extending from the fishing line connecting portion 32a to a position beyond the bent portion 32c.

What is important here is that even if the weight 5 is connected to the weight connecting portion 32d, the bent portion 32c is not deformed and no strain is generated, but the fishing hook 3 connected to the Harris connecting portion 32b.
When is pulled, the bent portion 32c is deformed, and strain is generated. This allows
When a fish bites the fishhook 3 and pulls it, the bent portion 3
The strain generated in 2c can be detected by the strain sensor 31. In the fishing line 20, two or more signal lines 21 are connected to the strain sensor 31, and the fishing line main body 22 is connected to the fishing line connecting portion 32a. The strain sensor 31 is generally temperature-compensated as described later, and in this case, the number of signal lines 21 is three.

Such a connecting fitting is not limited to this,
The connection fitting 33 as shown in FIG. 3 may be used. In this case, the fishing line connecting portion 33a and the Harris connecting portion 33b extend linearly with the bent portion 33c bent in an arc shape interposed therebetween, and the strain sensor 31 is fixed to the bent portion 33c. Also in this case, when a fish bites the fishing hook 3 and pulls it, a strain is generated in the bent portion 33c, so that the strain sensor 31 can detect the strain generated in the bent portion 33c.

Here, an example of a concrete configuration of the fish-belt detecting section 10 will be described in detail with reference to FIG.

That is, the Wheatstone bridge circuit 41 includes an input terminal 42 for inputting a change in the resistance value of the strain sensor 31 and a resistor 4 having a known resistance value.
3a to 43c are connected in series in a ring shape, two power supply terminals 45 are connected as voltage application terminals 44 to two opposing connection terminals, and the other two output terminals are input to the amplifier 47 as voltage measuring terminals 46. The output of the amplifier 47 to each driver 4
8a to 48c are input. In addition,
The drivers 48a to 48c respectively correspond to the display unit 11, the LED lamp 12, and the speaker 13 as the notification means.

In such a fish-spot detecting circuit, a change in the resistance value of the unknown strain sensor 31 occurs between the input terminals 42, which appears as a change in the voltage between the voltage measuring terminals 46. By utilizing this, a change in the resistance value of the strain sensor 31 can be detected.

According to such a circuit, it is possible to detect a change in the resistance value without considering the attenuation of the electric signal by the signal line 21. In addition, it is not necessary to measure the change in the resistance value of the strain sensor 31 as an absolute value, and it is sufficient to detect it as a relative value. Therefore, the change in the resistance value from the zero point can be detected by setting the state without bite to zero. do it. Of course, for example, the zero point may be adjusted before using any of the resistors 43a to 43c as a variable resistor. In order to improve the accuracy, the signal line 21
It is preferable to change the length and temperature compensation. That is, the temperature effect of the signal line 21 can be removed by adopting the three-wire connection method. In this case, there are three signal lines 21. Of course, it goes without saying that temperature compensation or the like can be performed by software.

Here, an example of the operation of the notification means will be described with reference to FIG. FIG. 5A shows a strain sensor 31.
It is an example of the measurement result of the voltage detected based on the change of the resistance value of, and it is assumed that it becomes a mountain shape that rises and falls with the passage of time. The peak voltage is 10V.

The display unit 11 as the notifying means is a 7-segment LED and displays the voltage change as a two-digit number as shown in FIG. 5B. For example, the peak voltage is "99". , 2.5V may be displayed as "25".

Further, as shown in FIG. 5C, the LED lamp 12 is displayed in two stages depending on the magnitude of the detected voltage, and the voltage generated by the change of the resistance value is 2.5V.
In the following area 51, the light may be turned on and off, and in the area 52 having a higher voltage, the light may be turned on.

Further, as shown in FIG. 5D, the speaker 13 has, for example, a magnitude of the detected voltage, for example, 2.
It suffices that the area 51 up to 5 V and the area 52 larger than 5 V provide two types of sounds, for example, high and low sounds, or sounds of different melody.

As described above, in the present invention, the strain caused by the fish biting is detected in the vicinity of the fishing hook and transmitted as an electric signal. Therefore, the fish line is not affected by the elongation of the fishing line and the tidal current. You can make an accurate judgment.

In the above-mentioned embodiment, the fishing line main body has two or more signal lines twisted together. However, if the conductive fishing line as described above is used as the signal line, the One obtained by twisting more than one signal line can be used as a fishing line.

As such a conductive fishing line, an in-situ chromium fiber reinforced copper alloy (chromium content of about 10%) having an outer diameter of 0.2 mm (cross-sectional area of 0.0308 mm ² ) and an insulating coating layer of a fluorine resin is used. An example is one in which two or more pieces provided with are twisted.
