2. Description of the Related Art In recent years, many fishing reels have been equipped with a line length measuring device as disclosed in Japanese Patent Application Laid-Open No. 1-276011 or Japanese Patent Publication No. Hei 4-2211 in order to improve fishing results. The fishing line length measuring device measures the amount of fishing line fed from the spool and the amount wound on the spool, and allows the user to drop the device on a predetermined shelf.

A fishing reel length measuring device disclosed in Japanese Patent Application Laid-Open No. 1-276011 discloses a fishing line length measuring device which stores the following information stored in a ROM of a microcomputer based on the actual number of rotations of a spool at the time of line feeding / winding. The yarn length calculation formula (1) is executed and the yarn length is measured. That is, FIG. 6 shows the rotational speed and the spool 1, the winding outside diameter and yarn length relationship of the fishing line 3 wound to those 該Su pool 1, in FIG, d _1: the fishing line 3 in specified winding level 5 in winding yarn diameter d _O: bottom diameter of the spool 1 d _m: fishing line 3 of the feeding, the outside diameter of the winding yarn which varies with the winding h: husband groove depth of the spool 1 to the specified winding level 5 s Is shown.

In the above conventional example, the spool 1 is n
and _a rotating and winding yarn diameter With this changes from d ₁ to d _m, the yarn length calculation formula stored in the microcomputer ROM L '= a / n · n a 2 + bn a ··· (1) Here, n: spool 1 of fishing line 3 up to specified winding diameter level 5

Incidentally, the total number of rotations n of the spool 1 and the actual number of rotations n
_a is counted by an up / down counter, respectively, and each count value is stored in the RAM of the microcomputer. On the other hand, the fishing line length measuring device for fishing reels disclosed in Japanese Patent Publication No. Hei 4-2211 stores a line length calculation formula having a line length-dependent constant determined by the line type in a ROM of a microcomputer. Before performing the yarn length measurement, a yarn length calculation formula is set according to the used yarn, and the set yarn length calculation formula is calculated and executed based on the number of rotations of the spool during yarn feeding / winding. It measures the yarn length.

[0006]

However, since the fishing line is used under various conditions, the diameter of the fishing line changes due to expansion and contraction due to changes in the temperature and water temperature of the fishing spot, and the fishing line may grow due to long-term use. The diameter of the thread becomes thinner, and the thread diameter of the spool changes slightly depending on the thread tension.

However, the conventional line length measuring apparatus described above cannot cope with such a change in the line diameter of the fishing line and the line winding diameter of the spool in accordance with the use condition, and can accurately measure the line length of the fishing line. It was not possible to do so. The present invention has been devised in view of such a situation, and is capable of coping with a change in a fishing line diameter and a spool winding diameter in accordance with a use condition, thereby providing a fishing reel capable of accurately measuring a line length. It is an object to provide a yarn length measuring device.

[0008]

In order to achieve the above object, a fishing reel line length measuring device according to the present invention comprises a sensor for detecting rotation of a spool supported by a reel body, and a sensor for detecting rotation of the spool. An up / down counter for counting up / down the output signal; calculating means for calculating the yarn length based on the yarn length calculation formula stored in the storage means based on the count value of the up / down counter; in a display for displaying the calculated line length, it is calculated by the calculating means the display in the displayed yarn length value itself external
Changed by switch operation, and the changed thread length value changed
And a correction means for correcting the constant determined by the yarn type of the above-described yarn length calculation formula by the arithmetic means on the basis of the above formula.

[0009]

According to the present invention, when the spool rotates due to the feeding and winding of the fishing line, the sensor detects the rotation of the spool and the up / down counter measures the rotation. Then, based on the count value of the up-down counter, and calculating means based on the line length formula stored in the storage means calculates the yarn length, and that the calculated value is displayed on the display unit as the line length Become.

[0010] Also, since fishing line is used under various conditions, the line diameter changes due to expansion and contraction due to changes in the temperature and water temperature of the fishing spot, and the line length increases and the line diameter becomes thin after long-term use. The diameter of the wound yarn of the spool also slightly changes according to the yarn tension.

[0011] Therefore, the present invention is calculated yarn length value is displayed in the display unit by itself by the arithmetic means to change by an external switch <br/> operation, changed the change yarn length value based on Zu
Come, and correct inverse calculation by the calculation means constant yarn length calculation formula to calculate the yarn length value, thereafter, calculates a basis yarn length calculating formula this constant, displayed on the display the calculated value as a yarn length I do.

Revolution N_aAre counted by the up / down counter 59, respectively.
Each count value is calculated by the RA of the microcomputer 27.
It is stored in M49.

[0020] Here, the case of inputting the rotational speed N and the total speed N _e of the spool 7 when the wound fishing line 19 from the bottom diameter D _O of the spool 7 to the end. First, when the power supply 43 is connected, the microcomputer 27 is initialized and placed in a start state. When the changeover switch 29 is pressed in such a state, the microcomputer 27 is set to the data input mode.

Next, one end of the fishing line 19 is tied to the bottom diameter of the spool 7, and the spool 7 is rotated by rotating the manual handle 13 to wind the fishing line 19 sequentially. At this time, since the level winder mechanism 63 shown in FIG. 1 traverses in the width direction of the spool 7 in synchronization with the rotation of the spool 7, the fishing line 19 is uniformly wound around the spool 7. Thus, when the spool 7 rotates in the winding direction, the up / down counter 59 is set to an up-counting state, and the pulse signal output from the sensor 57 for each rotation of the spool 7 is input. The data is taken into the up / down counter 59 through the interface 51 and is sequentially counted up.

When it is visually confirmed that the fishing line 19 has been wound up to the winding line diameter D of the specified winding diameter level 21, the winding operation of the fishing line 19 is stopped, and the specified winding diameter level data write switch is turned on. Press 31. Then, the count value of the up / down counter 59 is stored in the RAM 49 as the rotational speed N of the spool 7 up to the winding diameter level 21. Therefore, based on the basic data, first, the constant d = -πH with respect to the specified winding diameter level 21. / N will be determined.

Thereafter, the changeover switch 29 is pressed to set the microcomputer 27 to the data input mode again, and then the manual handle 133 is further rotated to operate the fishing line 19.
To the end. When the spool 7 rotates again in the line winding direction, the pulse signal output from the sensor 57 is taken into the up / down counter 59 via the input interface 51, and the up-counting is continued again.

After winding the fishing line 19 to the specified winding diameter level 21 and pressing the specified winding diameter level data write switch 31 to input a constant of d = -πH / N, data input is continued without pressing the changeover switch 29. Of course, the mode may be set. When the fishing line 19 is wound up to the specified winding diameter level 21 and the specified winding diameter level data write switch 31 is pressed, the digital display 3
5 may display the spool rotation speed N up to the specified winding diameter level 21 or perform thread length calculation processing with N = N _e ′.
The winding length up to the specified winding diameter level 21 may be displayed.
Further, the length of the winding line until the fishing line 19 is wound up to the end by further rotating the manual handle 13 is determined based on the number of spool rotations ( _Ne ′, _Ne ″,...). The thread length may be calculated up to the length and displayed on the digital display 35.

[0025] In Thus, fishing line 19 until the end, that is, if you press the final data write switch 33 where it was wound on the spool 7 to the winding yarn all major axis D _1, the count value of the up-down counter 59, wound stored in the RAM49 as the total speed N _e of the spool 7 to the yarn total diameter D _1, is determined constant for winding yarn full length _{e = π (D o + 2HN} e / N) is determined by the type of weft thread yarn length The writing of the constants d and e in equation (2) is completed.

Next, the yarn length measuring operation of the yarn length measuring device according to the present embodiment will be described with reference to the flowchart of FIG. 4, which is the same as the yarn length measuring device disclosed in Japanese Patent Laid-Open No. 1-276011. Are identical. When the program of FIG. 4 is started, first, in step S1, it is determined whether or not the fishing line 19 is extended.

If it is determined that the fishing line 19 is being fed out, the spool 7 is rotated in the forward direction with the feeding out of the fishing line 19, so that a signal in the forward direction is input from the sensor 57. The data is captured by the CPU 45 via the interface 51. Then, the up / down counter 59 is set to the up-counting state, and the spool 7
The pulse signal output from the sensor 57 in accordance with the rotation of is taken into the up / down counter 59 via the input interface 51, and is sequentially counted up (step S2).

[0028] In the next step S3, fetches the count contents N _a of the up-down counter 59 at every operation cycle of the microcomputer 27 to the CPU 45, the line length formula to constant d as described above, writing of e are completed The line length calculation of (2) is executed, and the calculation result is displayed on the digital display 35 as the payout line length L of the fishing line 19 (step S).
4).

On the other hand, if it is determined in step S1 that the fishing line 19 has been wound, the spool 7 is rotated in the reverse direction with the winding of the fishing line 19, so that the sensor 57 outputs a signal in the reverse direction. The data is fetched by the CPU 45 via the input interface 51, whereby the up / down counter 59 is set to the down count state. Then, the pulse signal output from the sensor 57 in accordance with the reverse rotation of the spool 7 is taken into the up / down counter 59, and subtracted from the content counted at the time of feeding by the down-counting operation (step S5).

[0030] Then, in the next step S6, the count content N _a of the up-down counter 59 at every operation cycle of the microcomputer 27 takes in the CPU 45, the winding yarn by calculating running yarn length calculation formula (2) The length, that is, the yarn length L obtained by subtracting the wound yarn length from the fed yarn length is calculated, and this is displayed on the digital display 35 as the fed yarn length (step S7).

As described above, according to the yarn length measuring device of this embodiment, similarly to the yarn length measuring device disclosed in Japanese Patent Application Laid-Open No. 1-276011, regardless of the thickness of the fishing line 19, the feed line length and winding length can be set. Although the yarn length can be measured with high accuracy, this embodiment has the following features in addition to the above configuration.
As described above, since the fishing line 19 is used under various conditions, the fishing line 19 expands and contracts due to a change in the temperature and water temperature of the fishing spot, and the fishing line 19 changes in length. The winding diameter D up to the specified winding diameter level 21 also slightly changes according to the yarn tension.

[0032] Therefore, the present embodiment is calculated in CPU45 displayed displayed value on the digital display 35 (yarn length L) itself is changed outside the switch operation is the change
Based on the changed yarn length value, the constants d and e of the above yarn length calculation formula (2) for calculating the initial yarn length value are back calculated by the CPU 45 and corrected, and thereafter the yarn length is calculated based on the constants d and e. The calculation formula (2) is calculated.

That is, as described in the flowchart of FIG. 4, the thread length calculation formula (2) in which the writing of the constants d and e is completed.
Is displayed on the digital display 35 as the feeding line length L of the fishing line 19, for example, when the feeding of the tackle is stopped, this display value becomes "63" as shown in FIG. (Meters). "

However, for example, the water depth value of a fish finder provided on a ship is “65 meters”,
When the value measured by the yarn length measuring device of the present embodiment has an error of 2 meters, when the one-shot correction mode changeover switch 37 on the operation panel 25 is operated, the microcomputer 2
7 is set to the correction mode, and the display value “63” on the digital display 35 blinks.

Each time the yarn length display value increase switch 39 is operated in this state, the display value "63" is changed to "64", "6".
When the display value adjustment is completed and the one-shot correction mode changeover switch 37 is operated again, the CP
In U45, based on the actual rotational speed N _a spool 7 at the time of calculating the "63 m" in the original yarn length formula L = dN _a ² + eN _a constant d, an e calculated back as yarn length L = 65 The modified constants d and e are stored in the RAM 49.

Thereafter, the corrected constants d, e
, The line length calculation formula (2) is calculated according to the flowchart described with reference to FIG. 4, and the calculated value is displayed on the digital display 35 as the line length of the fishing line 19. When the water depth value of the fish finder is “65 meters” and the display value of the digital display 35 is, for example, “68 (meters)”, the display value is set to “by operating the thread length display value decrease switch 41”. From "68" to "65", and thereafter, similarly, constants d and e of the yarn length calculation formula (2)
Can be corrected by back calculation.

As described above, in this embodiment, the CPU 45
In is calculated display value itself is displayed on the digital display 35
Change the body with an external switch operation and the changed changes
Based on the yarn length value, the constants d and e of the above yarn length calculation formula (2) for which the initial yarn length value was calculated are back calculated by the CPU 45 and corrected, and thereafter, the yarn length calculation formula (2) is based on this. Since the calculation is performed, the fishing line 19 expands and contracts due to a change in the temperature and water temperature of the fishing spot, and the line diameter changes. Even if the winding thread diameter D up to the specified winding diameter level 21 changes according to the thread tension, the thread length can be measured more accurately than the conventional thread length measuring device, and the practicality of the fishing reel is further improved. It was decided to improve.

In the above embodiment, it is visually determined that the fishing line 19 has been wound up to the specified winding diameter level 21 of the spool 7, and the specified winding diameter level data write switch 31 is operated after the determination. The applicant of the present invention has previously disclosed a fishing line reel detecting device which can automatically and reliably detect that the fishing line has reached a specified winding amount.
No. 9566.

In this fishing line detecting device, a spool for winding a fishing line is wound around the spool on the reel body in a fishing reel in which the spool is rotatably supported on the reel body. When the fishing line reaches a specified winding amount, a specified line winding amount detector that contacts the fishing line and indicates an appropriate winding amount of the fishing line is arranged. If such a specified thread amount detection device is mounted, it is possible to improve the accuracy without the need for visual judgment.

Further, for example, when the weight attached to the fishing line is dragged on the seabed by the tidal current or hits the fish, the vibration is transmitted to the reel body via the fishing line. Therefore, as shown by a two-dot chain line in FIG. 5, an earphone 65 is connected to the reel body 11 so that the vibration can be heard directly, or a piezoelectric sensor is attached to the reel body 11 and transmitted to the reel body 11. The vibration is converted into an electric signal, the vibration waveform is displayed on the display device 67 mounted on the operation panel 25, and the signal sound is wirelessly transmitted from the antenna 69 mounted on the reel body 11 to the headphone 71. You may do so.

According to such a fishing reel, the state of the seabed can be sensed and the point can be confirmed, and the predation sound of the fish can be sensed to increase the enjoyment of fishing.

[0042]

As described above, according to the line length measuring device of the first aspect, the fishing line expands and contracts due to changes in the temperature and water temperature of the fishing spot, and the line diameter changes, or the fishing line can be used for a long time. Even if the fishing line stretches and the line diameter becomes thin, or the winding line diameter changes in accordance with the line tension, the line length can be measured more accurately than with a conventional line length measuring device. The practicality has been further improved.
