BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel equipped with a line length measuring device for measuring the line length (feed amount) of a fishing line.

[0002]

2. Description of the Related Art In recent years, many fishing reels have been equipped with a thread length measuring device for measuring the length of a fishing line based on the number of rotations of a spool. It is possible to display the device's flying distance up to the point for fishing and throwing fishing.

The applicant of the present invention has previously disclosed the Japanese Patent Laid-Open No. 5-10.
In Japanese Patent No. 3567 and Japanese Utility Model Laid-Open No. 7-7435, a yarn length measuring device capable of measuring the yarn length regardless of the type of fishing line used is disclosed. Thus, JP-A-5-10356
The yarn length measuring device disclosed in Japanese Patent Publication No. 7 sets a specified winding diameter level at a position smaller than the maximum winding diameter of the spool, and determines the rotation speed of the spool when the fishing line is wound up to the specified winding diameter level. The total number of rotations of the spool when the fishing line is wound up to the full length of winding is detected by the number of rotations detection means, and the basic data such as the number of rotations of these spools and the diameter of the line up to the specified winding diameter level and the spool shape are used. After the thread length calculation formula is determined, the thread length calculation formula is calculated and executed based on the actual number of revolutions of the spool during actual fishing. This calculated value is displayed on the display as the thread length. There is.

The yarn length measuring device disclosed in Japanese Utility Model Laid-Open No. 7-7435 measures the yarn length by using an ultrasonic sensor, and includes a rotational speed detecting means for detecting the rotational speed of a spool and a transmitting device. The time until the ultrasonic wave emitted from the ultrasonic sensor on the fishing line winding surface of the spool is received by the ultrasonic sensor for receiving is measured by the time measuring means, and the diameter of the spool is calculated and measured based on the measured value. And a display for displaying the thread length calculated by this calculating means, a means for calculating the thread length based on the diameter of the thread obtained by the diameter measuring means for the thread winding and the value detected by the rotation speed detecting means. This yarn length measuring device does not require a troublesome input operation of basic data as compared with the yarn length measuring device disclosed in Japanese Patent Laid-Open No. 5-103567, and the yarn length can be increased. It has the advantage that it can be measured accurately.

[0005]

However, in the yarn length measuring device using the ultrasonic sensor as described above, 200 mA (milliampere) is required when the ultrasonic sensor is used.

In comparison with the starting current value of 300 μA (microampere) required by the yarn length measuring device disclosed in Japanese Patent Publication, the power consumption is remarkably large.

Therefore, conventionally, a yarn length measuring device using an ultrasonic sensor is generally used for an electric reel which uses an external battery having a large capacity as a power source, and is used for a manual reel incorporating a power source having a small capacity. When used, the power consumption was significant. On the other hand, the yarn length measuring device disclosed in Japanese Patent Application Laid-Open No. 5-103567 consumes less power than the yarn length measuring device using an ultrasonic sensor, and thus is widely used mainly for small manual reels. It has been pointed out that the user has to enter various basic data before using it for fishing.

Further, according to this line length measuring device, a slight error occurs between the actual feeding amount (actual length) and the measured value due to the influence of the elongation of the fishing line, etc. It has been pointed out that it is necessary to re-enter the data, and further, the basic data must be re-entered when an error occurs due to yarn breakage. The present invention has been devised in view of such circumstances, and has advantages of both yarn length measuring devices while compensating for the defects of both the yarn length measuring device using an ultrasonic sensor and the yarn length measuring device not using an ultrasonic sensor. An object of the present invention is to provide a fishing reel that exhibits the above advantages.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings.

The first yarn length measuring device of each embodiment described below is similar to the yarn length measuring device disclosed in the above-mentioned Japanese Utility Model Laid-Open No. 7-7435, and it has a transmitting ultrasonic sensor and a receiving ultrasonic wave sensor. An ultrasonic sensor is used, and its configuration and its yarn length measuring operation are the same as those of the conventional example. Further, the configuration of the second yarn length measuring device and its yarn length measuring operation are as described above. 5
Since it is the same as the yarn length measuring device disclosed in Japanese Patent Laid-Open No. -103567, detailed description thereof will be omitted here, and only the invented portion will be described.

1 to 3 show a first embodiment of a fishing reel according to a first aspect of the present invention. In FIG. 1, reference numeral 1 denotes a spool shaft 3 between side plates 7 and 9 of a reel body 5. A spool rotatably supported, 11 is a handle, and the handle 1
When the winding operation of 1 is performed, the rotational force is changed to the handle shaft 13,
The fishing line 19 is wound around the spool 1 by being transmitted from the drive gear 15 and the pinion gear 17 mounted on the spool shaft 3 to the spool shaft 3. The pinion gear 17 is configured to be rotatable on the spool shaft 3, slidable in the axial direction thereof, and engageable with and disengageable from a clutch portion 21 provided on the spool shaft 3. As shown in FIG. 5 operates the clutch lever 23 also serving as a thumb rest provided on the rear side of the clutch 5 to release the clutch engagement between the clutch portion 21 and the pinion gear 17 with the clutch plate 25, the spool 1 is in a spool free state, that is, the clutch mechanism 26 is clutch off. Then, the fishing line 19 is fed from the spool 1 by the casting operation.

In FIG. 2, 27 is a fishing rod mounting leg that is attached to the lower portion of the reel body 5, and 29 is a level wind mechanism mounted on the upper portion of the reel body 5 in front of the spool 1. 1, the traverse cam shaft 33 coupled to the pinion 31 that meshes with the drive gear 15 rotates, and the fishing line guide member 35 traverses in the axial direction of the spool 1, whereby the fishing line 19 is evenly distributed on the spool 1. The fishing line 19 wound around the spool 1 is wound evenly as the fishing line 19 is unwound.

As shown in FIGS. 1 and 2, a box-shaped electronic control mechanism housing 37 is mounted in front of the upper portion of the spool 1 between the side plates 7 and 9 of the reel unit 5 and inside the spool 1. A control means for controlling the first and second yarn length measuring devices described later is incorporated. Also, in FIG. 1, 39
Is a rotation speed detecting means for detecting the rotation speed of the spool 1 and its rotation direction. As shown in FIGS. 2 and 3, the rotation speed detecting means 39 is a pair of reed switches mounted in the electronic control mechanism housing 37. 41 and 43, and a magnet 45 that is fixed to the peripheral edge portion of the spool 43 on one end side so as to face the magnets 41 and 43.

The control means is the reed switch 4
Magnets 45 turn ON / OFF either 1,43 first
The forward / reverse rotation determination signal of the spool 1 obtained by FF is taken in, the rotational direction of the spool 43 is detected, the rotational speed is measured, and it is used for the calculation of the yarn length measurement described later. The calculation result is displayed as the line length of the fishing line 19 on the digital display 49 mounted on the operation panel 47 above the electronic control mechanism housing 37.

By the way, as shown in FIGS. 1 and 2, the clutch lever 23 is formed thicker in the vertical direction than the conventional clutch lever, and the spool facing surface 5 thereof is formed.
In the two sensor mounting holes 53 and 55 provided in 1, respectively,
Ultrasonic sensors 57 and 59 are attached so as to face the spool 1. Thus, the ultrasonic sensor 57 functions as transmitting means for emitting ultrasonic waves to the fishing line winding surface of the fishing line 19 wound on the spool 1, and the ultrasonic sensor 59 is reflected by the fishing line winding surface. As shown in FIG. 1, the center of the spool facing surface 51 of the clutch lever 23 that supports the reflected waves of the ultrasonic waves is formed in a V shape. Then, the sensor mounting holes 53 and 55 are provided in the corresponding portions, and the sensor mounting holes 5
By mounting the ultrasonic sensors 57 and 59 in 3, 55, respectively, the ultrasonic sensors 57 and 59 are arranged in a V shape with respect to the fishing line winding surface of the fishing line 19 and fired from the ultrasonic sensor 57. The reflected wave of the ultrasonic wave can be satisfactorily received by the ultrasonic sensor 59.

Since the clutch lever 23 is moved by the ON / OFF operation of the clutch mechanism 26, the distance between the ultrasonic sensors 57 and 59 mounted in the clutch lever 23 and the fishing line winding surface is changed by the clutch operation. If this happens, accurate yarn length measurement cannot be performed. Therefore, in the present embodiment, the clutch lever 23 is configured to move in the vertical direction of the reel body 5 with the spool shaft 3 as the center of rotation, as shown by the chain double-dashed line in FIG. 2. With such a configuration, The distance between the ultrasonic sensors 57 and 59 and the fishing line winding surface is always kept constant.

As shown in FIGS. 1 and 3, the frame frame 60 of the reel unit 5 has terminals 65, which can contact terminals 61, 63 of the ultrasonic sensors 57, 59 provided on the clutch lever 23 side. 67 are attached on the movement loci of the terminals 61 and 63, and the terminals 65 and 67 are connected to the control means in the electronic control mechanism housing 37. or,
As shown in FIG. 1, a button battery 69 is provided in one side plate 7.
A power supply case 71 in which is attached is provided, and the button battery 69 functions as a power supply for the yarn length measuring device and the like.

Then, in the electronic control mechanism housing 37,
The same yarn length measuring device as the yarn length measuring device disclosed in Japanese Utility Model Laid-Open No. 7-7435 is incorporated as a first yarn length measuring device.

As described above, this first yarn length measuring device is based on the time until the ultrasonic sensor 59 receives the reflected wave of the ultrasonic wave emitted from the ultrasonic sensor 57 to the fishing line winding surface. The thread winding diameter measuring means measures the thread winding diameter, and the thread length calculating means calculates the thread length based on the measured value and the detection value of the rotation speed detecting means 39, and the calculated value is digitally used as the thread length of the fishing line 19. The ultrasonic sensors 57, 5 are to be displayed on the display 49.
This type of yarn length measuring device using 9 can measure the yarn length with high accuracy.

However, in the manual reel in which an external battery having a large capacity is not used as the power source as in the present embodiment, the yarn length measurement by the ultrasonic sensors 57 and 59 consumes a large amount of power, so that the button battery 69 is significantly consumed. Therefore, in the present embodiment, in addition to the first yarn length measuring device, a yarn length measuring device which is the same as the yarn length measuring device disclosed in JP-A-5-103567 is used as a second yarn length measuring device. It is built into the control means.

This second yarn length measuring device is shown in FIGS.
As shown in, the specified winding diameter level 73 is set at a position smaller than the maximum winding diameter of the spool 1, and the spool 1 rotates when the fishing line 19 is wound up to the specified winding diameter level 73 in actual fishing. The number of rotations and the total number of rotations of the spool 1 when the fishing line 19 is wound up to the entire winding length are detected in advance by the number-of-rotations detecting means 39, and the number of rotations of these spools 1 and the diameter of the line wound up to the specified winding diameter level 73 are determined. After determining the thread length calculation formula based on the basic data and spool shape, spool 1 at the time of actual fishing
The yarn length calculation formula is calculated and executed based on the actual number of revolutions, and the calculated value is displayed as the yarn length on the digital display 49.
It consumes much less power than the first yarn length measuring device.

Then, as shown in FIG.
On the upper side, a yarn length measuring device changeover switch (hereinafter, referred to as a switch for alternately switching the first yarn length measuring device and the second yarn length measuring device).
A "changeover switch" 75 is attached, and the operation of the changeover switch 75 causes the first yarn length measuring device and the second yarn length measuring device to switch alternately. An indicator lamp 77 is mounted on the operation panel 47, and when the changeover switch 75 is operated to switch to the first yarn length measuring device, the control means causes the indicator lamp 7 to operate.
7 is turned on to inform the fisherman that the first yarn length measuring device operates.

In addition, in FIG. 1, 79 is an ON / OFF switch, 81 is a reset switch, and the control means and the digital display 49 are operated by turning on the ON / OFF switch 79.
When the reset switch 81 is operated, the display value of the digital display 49 is reset to "0". Since the fishing reel 83 according to the present embodiment is configured in this way, as before, the fisherman first rotates the spool 1 when the fishing line 19 is wound up to the specified winding diameter level 73 prior to actual fishing. Number and fishing line 1
The total number of rotations of the spool 1 when the spool 9 is wound up is detected by the number-of-rotations detecting means 39 in advance, and the basic data of the number of rotations of the spool 1 and the thread winding diameter up to the specified winding diameter level 73 and the spool shape are used. Determine the long calculation formula.

Then, at the time of actual fishing, the fisherman selects the changeover switch 7
When 5 is selected and the first yarn length measuring device is selected, the control means turns on the indicator lamp 77 to inform the fisherman that the first yarn length measuring device operates. Then, in such a state, the clutch lever 23 is operated to set the spool 1 in the spool free state, that is, the clutch mechanism 26 is set to the clutch OF.
When set to F, the fishing line 19 is paid out from the spool 1, the yarn length is measured by the first yarn length measuring device, and the reflected wave of the ultrasonic wave emitted from the ultrasonic sensor 57 is the ultrasonic sensor as described above. The time until it is received at 59 is measured by the bobbin diameter measuring means, and the bobbin diameter is measured based on the measured value. Then, the yarn length is calculated by the yarn length calculating means based on the yarn winding diameter and the detected value of the rotation speed detecting means 39, and the calculation result is displayed on the digital display 49.

By the way, compared to the case of shelving, it is not necessary to accurately measure the line length when the fishing line 19 is wound by a fish. Therefore, when the fisherman operates the clutch lever 23 to turn on the clutch when the fishing line 19 is fed to a predetermined shelf position based on the display value of the digital display 49, and then operates the changeover switch 75, the control means is operated. Means switching from the first yarn length measuring device to the second yarn length measuring device.

Therefore, the yarn length is measured by the second yarn length measuring device along with the winding operation, and the yarn length calculation formula is calculated based on the actual number of revolutions of the spool 1, and the calculated value is the yarn length. Is displayed on the digital display 49. When the fisherman operates the reset switch 81 after taking in the fish, the display value of the digital display 49 is reset to "0", and when the changeover switch 75 is operated again, the control means measures the second yarn length. The device is switched to the first yarn length measuring device. Then, when the fisherman again turns off the clutch mechanism 26 to feed the fishing line 19, the first yarn length measuring device again measures the yarn length.

As described above, the present embodiment is provided with the first yarn length measuring device using the ultrasonic sensors 57 and 59 and the second yarn length measuring device not using the ultrasonic sensor, and either one of them is used. By providing a changeover switch 75 for appropriately selecting, the fisherman can arbitrarily select both yarn length measuring devices.
As described above, in the winding operation of the fishing line 19 which does not require accurate measurement of the line length as compared with the shelving, the second power consumption is small.
By using the above-described thread length measuring device, it is possible to prevent the button battery 69 having a small capacity from being significantly consumed, and by operating the highly accurate first thread length measuring device at the time of feeding the fishing line 19, it is possible to obtain an accurate result. Shelving is possible, and therefore, while compensating for the defects of both the first yarn length measuring device using the ultrasonic sensors 57 and 59 and the second yarn length measuring device not using the ultrasonic sensors, both yarn lengths It has become possible to bring out the advantages of the measuring device.

[0039] Figures 4 and 5 show the fishing reel according to a second embodiment of claim 1, the present embodiment, instead of the changeover switch 75, ON / OFF operation of the clutch mechanism 26 by the clutch lever 23 The first yarn length measuring device and the second yarn length measuring device are switched in tandem with the above. The magnet 85 is attached to the side plate 9 side end of the clutch lever 21 as shown in the figure. Reed switches 87 and 8 that are turned on / off by this magnet 85
9 are arranged on the frame body 60 in correspondence with ON / OFF of the clutch mechanism 26.

When the clutch lever 23 is at the position shown in FIG. 5, the clutch mechanism 26 is in the clutch ON state. At this time, the reed switch 87 is turned ON by the magnet 85 and the clutch is turned ON. A signal is input to the control means, and the control means that has input the clutch ON signal selects the second yarn length measuring device.

When the clutch lever 23 is moved downward from the position shown in FIG. 5 to turn off the clutch mechanism 26, the reed switch 89 causes the magnet 85 to move.
The clutch OFF signal is input to the control means.
The control means to which the F signal is input is switched from the second yarn length measuring device to the first yarn length measuring device.

Since the other structures are the same as those of the first embodiment, the same components are designated by the same reference numerals and the description thereof will be omitted. Fishing reel 91 according to the present embodiment
Since this is configured as described above, when the clutch lever 23 is operated to turn off the clutch mechanism 26 as described above, the reed switch 89 causes the magnet 85 to move.
The control means, which has been turned on by inputting the clutch off signal, switches from the second yarn length measuring device to the first yarn length measuring device. Therefore, when the fishing line 19 is fed out, the first yarn length measuring device is turned on. The yarn length is measured by.

When the clutch lever 26 is operated to turn on the clutch mechanism 26, the reed switch 87 is turned on by the magnet 85, and the control means which has input the clutch ON signal causes the first yarn length measurement. Since the device is switched to the second line length measuring device, the fishing line 19
The yarn length is measured by the second yarn length measuring device in accordance with the winding operation.

Therefore, according to the present embodiment as well, the capacity can be reduced by using the second line length measuring device which consumes less power during the winding operation of the fishing line 19 which does not require accurate line length measurement as compared with shelving. It is possible to prevent the small button battery 69 from being significantly consumed, and by operating the highly accurate first line length measuring device when the fishing line 19 is fed out, accurate shelving is possible, and the ultrasonic sensors 57, 59 are provided. It has become possible to make full use of the advantages of both the yarn length measuring devices while compensating for the drawbacks of both the first yarn length measuring device using the and the second yarn length measuring device not using the ultrasonic sensor.

In addition, according to the present embodiment, the yarn length measuring device is switched in conjunction with the ON / OFF operation of the clutch mechanism 26, which is more practical than the fishing reel 83 described above. Have advantages. In the first embodiment shown in FIG. 1, the changeover switch 75 provided on the operation panel 47 is operated to switch between the first yarn length measuring device and the second yarn length measuring device. Alternatively, a switching lever may be provided on the reel unit 5 and the two yarn length measuring devices may be switched by operating the switching lever.

Conventionally, in the electric reel, in addition to the spool motor that drives the spool, the clutch mechanism is
Clutch ON / OF for operating the clutch motor by incorporating the clutch motor for N / OFF in the reel unit.
It is well known that the F switch is provided on the operation panel, but it goes without saying that the present invention can be applied to such an electric reel, and even in such an electric reel, operation of the clutch ON / OFF switch The first yarn length measuring device and the second yarn length measuring device may be switched in conjunction with.

Further, although not shown, a predetermined "condition" for switching the first yarn length measuring device to the second yarn length measuring device is set in advance in the control means as in the embodiment of the invention according to claim 2. It may be stored and the control means may automatically switch the first yarn length measuring device to the second yarn length measuring device when the condition is satisfied during actual fishing.

The "conditions" include the operating time of the first yarn length measuring device, the number of revolutions of the spool 1, the diameter (winding amount) of the fishing line 19, and the first yarn length measurement, for example. The time for measuring the yarn length by the device is detected by a timer, and when the yarn length measurement by the yarn length measuring device elapses for a certain time, the control means switches the first yarn length measuring device to the second yarn length measuring device. Alternatively, based on the diameter of the fishing line 19 measured by the diameter of the fishing line measuring means, when the diameter of the fishing line reaches a predetermined diameter, the control means causes the first thread length measuring device to operate as the second thread length measuring device. The button battery 69 can be prevented from being significantly consumed by these embodiments as well.

6 to 8 show an embodiment of claim 3 , and this embodiment has a second priority over the first yarn length measuring device.
The power consumption is prevented by measuring the yarn length by the yarn length measuring device, and the control means activates the first yarn length measuring device based on the predetermined condition so that the second yarn length measuring device operates. By correcting the measured value with the measured value of the first yarn length measuring device, it is possible to accurately measure the yarn length.

The present embodiment will be described below. The same parts as those in the above-mentioned embodiments are indicated by the same reference numerals. Also in this embodiment, the magnet 85 shown in FIG. 5 is attached to the clutch lever 23, and the reed switches 87 and 89 are attached to the frame body 60.

The signals of the reed switches 87 and 89 are input to the control means, and the control means first operates the second yarn length measuring device by turning off the clutch lever 23. Also, the control means,
After the operation of the second yarn length measuring device, as a predetermined condition for operating the first yarn length measuring device, the yarn length measuring time (for example, 5 to 10 minutes) by the second yarn length measuring device is preset, It is stored, and this measurement time is measured by a timer and input to the control means.

Then, when the yarn length is measured by the second yarn length measuring device over the set predetermined time, the control means displays the measured value of the second yarn length measuring device on the digital display 4.
While displaying it on 9, the first yarn length measuring device is operated together with the second yarn length measuring device to measure the yarn length with both yarn length measuring devices, and the measured values of both yarn length measuring devices are compared. Has become.

As described above, the ultrasonic sensor 5
The first yarn length measuring device using 7, 59 can measure the yarn length with higher accuracy than the second yarn length measuring device that does not use the ultrasonic sensor. Therefore, the control means compares the measured values of the two yarn length measuring devices, and when there is a difference of a predetermined value or more between the two measured values, it is determined that an error has occurred in the second yarn length measuring device and the measured value is the first. In accordance with the measured value of the yarn length measuring device, the basic data of the yarn length calculation formula is automatically corrected, and hereinafter, the second yarn length measuring device performs the yarn length measurement by the corrected yarn length calculation formula. It has become.

Now, a method of correcting the basic data of the yarn length calculation formula will be described. FIG. 6 shows an explanatory view of a yarn length measuring method by the first yarn length measuring device. This yarn length measuring device is emitted from the ultrasonic sensor 57 for transmission as disclosed in Japanese Utility Model Laid-Open No. 7-7435. The bobbin diameter measuring means measures a time t until the generated ultrasonic wave is reflected by the fishing line winding surface 93 of the spool 1 and reaches the ultrasonic wave sensor 59 for reception, and the ultrasonic wave velocity V (331 m) in the air is measured. / Sec.) And the measurement time t, the distance a from the ultrasonic sensors 57, 59 to the fishing line winding surface 93 is calculated by the equation a = t × V / 2, and then the ultrasonic sensors 57, 59 are calculated. From the distance c (constant) between the shaft center b of the spool shaft 3 and the spool b, the diameter D of the fishing line 19 is obtained by the formula D = (c−a) × 2, and the actual fishing number detected by the rotation speed detecting means 39. On the basis of the actual rotational speed Na of the spool 1 at this time and the diameter D of this line, the line length L of the fishing line 19 is calculated by the formula L = πDNa. It is what you want.

Therefore, the unit rotational speed (for example, Na = 1)
The yarn length L ′ per hit is L ′ = πD. On the other hand, FIG. 7 shows an explanatory view of a yarn length measuring method by the second yarn length measuring device, wherein D _0, D _1, D ₂ and H are respectively D ₀ : bottom diameter D _{1 of} spool _1. : fishing line 19 to the end wound up during the winding yarn total diameter D _2: the fishing line 19 is specified winding level 73 until the wound when winding yarn diameter H of: groove of the spool 1 to the specified winding level 73 Depth is shown respectively.

As disclosed in Japanese Unexamined Patent Publication No. 5-103567, the yarn length measuring device has the rotation speed detecting means 3
On the basis of the number of revolutions N of the spool 1 up to the winding diameter level 73 measured in 9 and the total number of revolutions Ne of the spool 1 with respect to the winding full length diameter D ₁ , the yarn length calculation formula L = dNa stored in the control means. ² + eNa ... However, Na : Actual rotation speed of the spool 1 at the time of actual fishing d = -πH / N: Constant ... e = π (D ₀ + 2HNe / N): Constant ... Ne : Total number of rotations N of spool ₁ up to winding full length diameter D ₁ : Spool 1 at actual fishing after determining the constants d and e of the number of rotations of spool 1 up to winding diameter level 73 The control means calculates the equation based on the actual number of revolutions Na and obtains the yarn length L.

Then, by substituting the values determined by the formula for the constants d and e of the formula, L = dNa ² + eNa = −πH / N · Na ² + π (D ₀ + 2HNe / N) · N
Since it is a, the yarn length L ′ per unit number of rotations (Na = 1)
Is L ′ = − πH / N + π (D ₀ + 2HNe / N).

The yarn length L'per unit number of rotations is
Since both the first and second yarn length measuring devices should be the same, from the equation, πD = −πH / N + π (D ₀ + 2HNe / N) D = −H / N + D ₀ + 2HNe / N = (− H + D ₀ N + 2HNe) / N, where H, D ₀ , N, and Ne are constants that have already been input in determining the formula, and therefore −H + D
_{0 When} replaced with N + 2HNe = A, D = A / N.

As a result, N = A / D, and since "N" obtained here is obtained by the first yarn length measuring device, the control means sets this "N" to the second yarn. By substituting "N" for the yarn length measurement by the length measuring device, the constants d and e can be calculated from the equations d'and e '
Then, based on the corrected constants d ′ and e ′, the equation is calculated as L = d′ Na ² + e′Na. , Based on the thread winding diameter D obtained by the first thread length measuring device,
The rotation speed "N" of the spool 1, which is the basic data of the yarn length calculation formula of the second yarn length measuring device, and the constants d and e are corrected, and thereafter the formula based on the corrected constants d'and e'is calculated. It is designed to be executed to measure the yarn length.

After that, the control means stops the operation of the first yarn length measuring device and again performs the yarn length measurement by the second yarn length measuring device by the formula, and inputs the signal from the timer. Then, the same steps are repeated thereafter. Since the present embodiment is configured in this way, FIG.
As shown in the flow chart of
When 3 is operated to turn off the clutch, the yarn length is measured by the second yarn length measuring device, and the measured value is displayed on the digital display 49 as the yarn length (step S1).

At the same time, the control means inputs a signal from the timer to determine whether or not the time measured by the second yarn length measuring device has reached a preset predetermined time (step S2). When it is determined that the predetermined time has elapsed, the control means operates the first yarn length measuring device together with the second yarn length measuring device, and as a result, the yarn length measurement is performed by both yarn length measuring devices. (Step S3).

As described above, the value measured by the second yarn length measuring device is displayed on the digital display 49 at this time. Then, the control means compares the measured values of the two yarn length measuring devices (step S4), and when the two measured values have a certain difference or more, the measured value by the second yarn length measuring device is compared with the first yarn length. The measured value of the measuring device is corrected and displayed on the digital display 49 (steps S5 and S6), and the basic data of the yarn length calculation formula in the second yarn length measuring device is automatically calculated as described above. Correction, and the operation of the first yarn length measuring device is stopped (step S7). Then, returning to step S1, the corrected yarn length calculation formula (the above formula)
Thus, the yarn length measurement by the second yarn length measuring device is repeated again.

When the measured values of both yarn length measuring devices do not differ by more than a certain value in step S4, the first yarn length measuring device is stopped because the measured value of the second yarn length measuring device is accurate. At the same time (step S7), the process returns to step S1 without correcting the yarn length calculation formula of the second yarn length measuring device.

As described above, in the present embodiment, the second yarn length measuring device which operates the first yarn length measuring device under the predetermined condition set in advance and operates in priority to the yarn length measuring device. Since the measured value and the basic data are corrected appropriately, according to the present embodiment, the power consumption of the power source can be reduced and the yarn length can be accurately measured. In addition, according to the present embodiment, the basic data of the second yarn length measuring device is automatically corrected, so that the actual length and the measured value are affected by the elongation of the fishing line 19 due to long-term use. Even if there is a slight error in, there is no need for the fisherman to re-enter the basic data one by one.

Up to 100 to less than 500 revolutions and the number of revolutions of the spool 1. When the number of rotations is 500 or more, the first yarn length measuring device is activated every 200 rotations (500, 700, 900 ...), and various settings can be made in consideration of the practical range of the fishing reel. Is.

Further, the total number of revolutions of the spool 1 (the total number of revolutions of the spool 1 up to the winding full length diameter D ₁ at the time of inputting the basic data of the second yarn length measuring device) was divided into X equal parts (previously stored). The rotation speed of the spool 1 at this time can be set as a predetermined condition. In this case, if it is stored as X = 20, for example, if the total number of rotations of the spool 1 up to the winding yarn full length diameter D ₁ at the time of inputting the basic data is 3000, then every 150 rotations. The first yarn length measuring device operates.

In the second embodiment, the "work amount (total use time or total winding amount)" by the second yarn length measuring device is set as a predetermined condition. For example, the total use time is 8 hours / One day (6 hours of actual fishing, 2 hours of movement) Total winding amount 7200 m / 1 day (when 6 hours of actual fishing is performed once every 5 minutes for fishing at a water depth of 50 m) When the condition is satisfied, the first yarn length measuring device may be activated.

Therefore, the fisherman can easily determine the current tension of the fishing line 111 by looking at the display on the display unit 141a. Therefore, as described above, the high tension (3 to 5 kg) applied to the fishing line 19 is set and stored in the control unit in advance, and the above-described line tension measuring device is mounted on the fishing reel to operate the second line length measuring device. After that, when the thread tension measuring device detects a predetermined high tension,
The control means may operate the first yarn tension measuring device.

Therefore, the predetermined purpose according to each of these embodiments can achieve the intended purpose as in the embodiments described with reference to FIGS. 6 to 8. 16 and 17 are flowcharts showing a method of controlling a fishing reel according to another embodiment of claim 3 , and in this embodiment, the second yarn length measurement is prioritized over the first yarn length measuring device. By measuring the yarn length by the device, consumption of the power source is prevented, and the control means operates the first yarn length measuring device by the manual operation of the fisherman to make the first measured value of the second yarn length measuring device. It is characterized in that it is corrected by the measured value of the yarn length measuring device.

That is, in actual fishing, when the fisherman operates the reset switch 81 provided on the operation panel 47 of FIG. 1 to feed the fishing line 19, the digital display 49 displays "0". The control means which input the signal is the first
The yarn length measuring device and the second yarn length measuring device are simultaneously operated to measure the yarn lengths by the two yarn length measuring devices. The digital display 49 displays the measurement value of the second yarn length measuring device.

Thus, the control means has a predetermined time (for example,
After measuring the yarn length by the both yarn length measuring devices for 5 to 10 minutes), the measured values of the two yarn length measuring devices are compared, and when the measured values have a difference of a predetermined value or more, the second Assuming that an error has occurred in the yarn length measuring device, the measured value is adjusted to the measured value of the first yarn length measuring device to display the corrected measured value on the digital display 49, and the same as in the above-described embodiment. The basic data of the yarn length calculation formula of the second yarn tension measuring device is automatically corrected, and the yarn length is measured by the corrected yarn length calculation formula.

After that, the control means stops the operation of the first yarn length measuring device, and thereafter, the yarn length measurement by the second yarn length measuring device is continued, and the angler thereafter resets the reset switch again. When 81 is operated, the control means which has input the signal repeats the above steps. or,
As described above, the control unit is configured to perform the predetermined time (for example, 5 to 1).
After measuring the yarn length by the both yarn length measuring devices for 0 minutes), the measured values of the both yarn length measuring devices are compared, but when the measured values do not differ by more than a predetermined value, the second yarn Assuming that the value measured by the length measuring device is accurate, the first yarn length measuring device is stopped and the yarn length measurement by the second yarn length measuring device is continued without correction. Then, when the fisherman operates the reset switch 81, the control means which has input the signal repeats the above-mentioned steps.

Since the present embodiment is configured in this way, the fisherman operates the reset switch 81 in order to feed the fishing line 19 as shown in the flow charts of FIGS. 16 and 17, and the display of the digital display 49 is displayed. When it is set to "0" (step S8), the control means that receives this signal operates the first yarn length measuring device and the second yarn length measuring device at the same time to perform the yarn length measurement by both yarn length measuring devices. (Step S9), the digital display 49 displays the measurement value of the second yarn length measuring device.

Then, the control means measures the yarn lengths by the two yarn length measuring devices for a predetermined time, compares the measured values of the two yarn length measuring devices (step S10), and sets both measured values at the predetermined values. If it is determined that there is no difference, the value measured by the second yarn length measuring device is determined to be accurate, and the first yarn length measuring device is stopped (step S11), and the second yarn length is corrected without correction. The yarn length measurement by the length measuring device is continued (step S12), and the process returns to step S8.

On the other hand, when it is determined in step S10 that the two measured values have a difference of a predetermined value or more, the control means sets the second value.
It is assumed that an error has occurred in the yarn length measuring device, and the measured value is corrected to the measured value of the first yarn length measuring device, and the basic data of the yarn length calculation formula is automatically corrected (step S1).
3) Then, the corrected measured value is displayed on the digital display 49 (step S14).

After that, the control means stops the operation of the first yarn length measuring device (step S15), and thereafter, the yarn length measurement by the second yarn length measuring device is performed by the corrected yarn length calculation formula. Continuing (step S16), the process returns to step S8. As described above, in the present embodiment, the first and second yarn length measuring devices are operated by the operation of the reset switch 81 by the fisherman, and the measurement value and the basic data of the second yarn length measuring device are appropriately corrected. After that, the second yarn length measuring device is preferentially operated, so that according to the present embodiment as well,
The power consumption of the power source can be reduced and the yarn length can be accurately measured.

Also in the embodiment, since the basic data of the second yarn length measuring device is automatically corrected, the actual length and the measured value are affected by the elongation of the fishing line 19 due to long-term use. It has the advantage that the angler does not have to re-enter the basic data, even if some error occurs between the two. In each of the above embodiments, the ultrasonic sensor 5 of the first yarn length measuring device is used.
7, 59 were mounted on the clutch lever 23 which also serves as a thumb rest, but the applicant of the present invention, as in the yarn length measuring device disclosed in Japanese Patent Laid-Open No. 5-23082, has an ultrasonic sensor facing the fishing line winding surface. The one mounted on the electronic control mechanism housing,
As disclosed in Japanese Utility Model Laid-Open No. 7-7435, it goes without saying that a yarn length measuring device having a structure in which a sensor support is attached to the lower portion of a thumb rest and an ultrasonic sensor is attached to this can be used as the first yarn length measuring device. Is.
