Description

[Detailed explanation of the invention] (a) Technical field of the invention The invention relates to a fishing reel, and more specifically, the invention relates to a fishing reel that is capable of measuring fishing line reeling and winding with high accuracy during fishing, and that protects the rod tip. This relates to a fishing reel that has made this possible.

(b) Prior art and problems In recent years, fishing reels such as casting reels have been equipped with mechanisms that measure the length of the fishing line let out from the spool or the length of the line wound onto the spool, and display these digitally. Additions are emerging and these functions are being controlled by microcomputers.

However, as a method of measuring the amount of fishing line let out and the amount of winding, as shown in Japanese Patent Application Laid-Open No. 57-155931, etc., the rotation of the spool is detected by a sensor, and the sensor detects the rotation of the spool. This is carried out by counting the pulse signals that occur, importing this counted value into a microcomputer every calculation cycle, calculating it, and outputting the calculation result to a display section.

However, the winding diameter of the fishing line on the spool decreases when the line is paid out and increases when the line is wound up, so the amount of line paid out or wound up per revolution of the spool changes depending on the winding diameter of the line. do. Therefore, simply counting the number of pulses per unit length (for example, per 1 m) obtained from the rotation of the spool does not allow highly accurate yarn length measurement.
If the wire diameter of the thread used changes, the rate of change in the winding diameter of the thread during unwinding and winding will also differ, so the measurement method described above allows for highly accurate thread measurement according to the thread diameter. It is not possible to measure the amount of unwinding and winding. In addition, due to repeated thread unwinding and winding, an error occurs between the actual amount of thread unwinding and the value displayed on the display. did not reach zero, and therefore there was a problem in which the device could accidentally hit the tip of the rod, causing the tip to break.

(c) Purpose of the invention The present invention is a solution to the conventional problems as described above.The purpose of this invention is to improve the measurement accuracy of the length of the yarn being let out and the length of the winding yarn after being let out, and to improve the accuracy of the measurement of the yarn length at the tip of the rod. To provide a fishing reel with guaranteed protection.

(d) Structure of the invention For this purpose, the fishing reel of the invention includes a reel body, a spool rotatably supported on the reel body around which a fishing line is wound, and a sensor for detecting the rotation of the spool. , the signal from this sensor is counted up to calculate the number of rotations of the spool at the time of yarn payout, and the up/down counter is counted down by the signal from the sensor, and the yarn is fed out based on the counted value of this up/down counter. means for calculating the line length and winding line length; a display section for displaying the measured and calculated line length; a thread diameter input means for selecting various thread length calculation formulas created to approximate curves obtained by actual measurements for each diameter in accordance with the diameter of the fishing line wound on the spool; and a thread length calculation means. This device consists of a means for determining that the length of the fishing line from the rod tip to the hook reached when measuring the length of the wound line, and a warning alarm that sounds in response to a command from the determining means. It is.

and a power switch 7 are provided in a watertight manner. Additionally, the storage body 4 has built-in sensors that detect the rotation and direction of the spool, and a microcomputer (both of which will be described later) that calculates the length of the unwinding and winding yarn based on the rotational speed of this sensor. , the storage body 4 further includes a small battery storage section 8

Figure 3 shows how to set the thread diameter and total thread length in the casting reel of the present invention, measure the length of the thread to be paid out and wound up, and reset the thread length display to zero before the given length of the thread is completely wound up. This is a diagram showing the configuration of the internal circuit, and 10 is a microcomputer that controls and manages the program memory, data memory, and input/output devices, and executes the calculations and transfer processing necessary to process a given job. It is composed of a CPU 11, a ROM 12 that stores arithmetic processing programs, etc. for the CPU 11, a RAM 13 that stores arithmetic results, etc., an input port 14, and an output port 15.

A sensor 16 detects the rotation and direction of the spool 2, and is composed of a pair of Hall elements 16a and a magnet 16b fixed to the spool 2, and the magnetic field of the magnet 16b is applied to the Hall element 16a, 16a, the Hall effect causes the Hall elements 16a, 16a to
A voltage with a predetermined phase is generated from the spool 2, and depending on which of the two generated voltages is generated first, it is determined whether the spool 2 rotates in the normal or reverse direction, and both generated voltages are sent to the waveform shaping circuit 16c. By adding it, it is converted into a pulse signal proportional to the rotation of the spool 2, and this pulse signal is taken into the CPU 11 via the input port 14, and is added or subtracted by the built-in up/down counter 17. Based on the counted values, the length of the yarn to be let out and the length to be wound up are calculated for each calculation cycle. The results of the arithmetic processing performed by the CPU 11 are stored in the RAM 13 or output to the display section 5 through the output port 15.

Further, an alarm drive circuit 22 is connected to the output port 15, and an alarm 23 is connected to this drive circuit 22. The alarm 23 is used as a reference sound for timing the countdown after landing on the water and when pulling the bait after settling. 24 is a power source.

FIG. 4 shows the procedure of the mode switching means by operating the mode switching switch 18, and FIG. 5 shows the procedure of the thread diameter input means.
The figures each show the procedure of the yarn total length input means, and FIG.
is stored in

Next, the operation of the embodiment of the present invention configured as described above will be explained.

First, when the power switch 7 is turned on, the microcomputer 10 is initialized. When the mode changeover switch 18 is pressed intermittently and sequentially in this state, the microcomputer 10 selects the yarn diameter input mode shown in step S1 in FIG. 4, the total yarn length input mode shown in step S2, and the total yarn length input mode shown in step S3 in FIG. The mode is sequentially switched to yarn length measurement mode.

Steps S1 to S3 shown in FIG. 4 are performed cyclically by operating the switch 18, and this is called the normal mode. In this normal mode, when the on/off mode switch 21 is pressed once, the mode becomes an off mode, that is, a state in which all inputs are not accepted. When the on/off mode switch 21 is pressed again, the mode returns to one of the normal modes before the off mode.

When the microcomputer 10 is set to the thread diameter input mode, the "LINE" 5a of the display section 5 lights up or flashes, indicating that the mode is the thread diameter input mode. At the same time, the thread diameter is enabled to be specified, and the thread diameter input processing routine shown in FIG. 5 can be executed by repeatedly turning on the set switch 19.

In the thread diameter input processing routine shown in FIG.
Steps S13 to S15 and steps S16 to S18 are executed cyclically, for example, three types of thread diameters of 0.28
The display of mm, 0.30mm, and 0.35mm and the corresponding thread length calculation formula will be set.

First, when the set switch 19 is turned on for the first time, in step S10, the display section 5
a and the selected thread length calculation formula are reset, and then the thread diameter is set to 0.28 mm as shown in step S11.
Display processing is executed. That is, the data of the thread diameter of 0.28 mm is read from the ROM 12, and the data is outputted to the display section 5 through the output port 15, and the numerical value ".28" is displayed on the thread diameter display section 5b. Then, the process moves to the next step S12, and a calculation formula y = a ₁ x ³ + b ₁ x ² + c ₁ x (where y: thread length, x : spool rotation speed), and at the same time set the constants a ₁ , b ₁ , and c ₁ of the primary to tertiary terms. These constants a ₁ , b ₁ , c ₁ are suitable for yarn length measurement with a yarn diameter of 0.28 mm, and these constants and cubic equations are ROM1
It is stored in 2.

Then, if the ON operation of the set switch 19 is completed once, the thread diameter of 0.28 mm and its thread length calculation formula will be selected.

If the set switch 19 is pressed once more, the process advances to step S13, where the display of ".28" on the display section 5b that was set when the set switch 19 was operated for the first time is reset, and the corresponding thread is reset. Long formulas are also reset. Then, the process advances to the next step S14, where processing for displaying the thread diameter of 0.30 mm is executed. In other words, read the data of thread diameter 0.30mm from ROM12 and send it to output port 1.
5 to the display section 5, the numerical value ".30" is displayed on the thread diameter display section 5b. Next, proceed to step S15, and calculate the calculation formula
=a ₂ x ³ +b ₂ x ² +c ₂ x is set, and at the same time constants a ₂ , b ₂ , and c ₂ of the first to third order terms are set.

Furthermore, when the set switch 19 is pressed, the process proceeds to step S16, where the display and calculation formula set for the second time are reset in the same manner as described above, and the process proceeds to the next step S17, where the thread diameter of 0.35 mm is displayed. When this thread diameter display process is completed, the step
Proceed to S18, and use the calculation formula suitable for measuring the length of yarn for unwinding and winding with a yarn diameter of 0.35 mm, y = a ₃ x ³ + b ₃ x ² +
Set c ₃ x and at the same time set the constants a ₃ ,
Set b ₃ and c ₃ .

Therefore, when the line diameter of the fishing line 3 wound around the spool 2 is displayed on the display section 5b, if you stop turning on the set switch 19, the formula for calculating the line diameter displayed on the display section 5b will be set. Based on this calculation formula, the length of the unwinding yarn and the length of the winding yarn are calculated.

Next, the processing procedure for inputting the actual total length of the thread wound around the spool 2 will be described with reference to FIG.

When the microcomputer 10 is set to the total yarn length input mode by operating the mode changeover switch 18, "CAP." 5d on the display section 5 is lit to indicate that the mode is the total yarn length input mode, and at the same time, A process of setting data corresponding to the maximum display value of the yarn length display section 5c of the display section 5 in the RAM 13 as shown in step S20 in FIG. 6 is executed. That is, the yarn length display section 5c in this embodiment
The maximum display value is "199" (unit: meters), and the corresponding data previously written in the ROM 12 is written to the RAM 13 by the CPU 11, and the maximum numerical data is sent through the output port 15. It is output to the yarn length display section 5c,
"199" is displayed on the yarn length display section 5c. Next, the process advances to step S21, and it is determined whether the set switch 19 has been pressed. If the result of this judgment is "YES", that is, the set switch 19 is pressed once, the step
Shifts to S22, and the switch signal is input port 1
4 to the CPU 11, and subtracts 199-1. As a result, the numerical contents stored in RAM13 are counted down by -1, and at the same time
199-1=198 is displayed on the yarn length display section 5c (step S23).

Thereafter, if the set switch 19 is turned on intermittently in the same way, the contents in the RAM 13 will be counted down one by one, and the displayed contents on the thread length display section 5c will also change from 198→197→...→0. Become. Therefore, when the value displayed on the thread length display section 5c reaches a value corresponding to the substantially total length of thread wound around the spool 2, for example "130", the set switch 19 is turned off.
If the on/off operation is stopped, 130 m will be set in the RAM 13 as the actual total yarn length data. Then, when the reset switch 20 is turned on, the yarn length value being displayed becomes zero.

Note that if the set switch 19 is pressed continuously for about 1 to 2 seconds, a predetermined number of free-running pulses, for example, 8 Hz, will be generated. In combination with this, the total yarn length can be set more quickly.

Next, the operation of measuring the length of the fishing line 3 let out and the length of the wound line during cast fishing will be explained according to the processing procedure shown in FIG. 7.

When actually fishing, step S1 in Figure 4,
After passing through S2, the mode changeover switch 18 is operated to set the microcomputer 10 to yarn length measurement mode. As a result, "DIST." 5e on the display section 5 is lit, indicating that the yarn length measurement mode is in effect.

In this state, when a fishing rod (not shown) with the reel body 1 attached is swung down, a tackle (not shown) connected to the fishing line at the tip of the rod is thrown toward a point, and as the tackle flies to the point, The fishing line 3 wound around the spool 2 is sequentially let out, and at the same time, the spool 2 is rotated in the line payout direction. This direction of rotation is defined as forward rotation.

When the measurement processing program is thereby started, first, in step S30, it is determined whether or not the yarn is being let out. This is because the magnetic field of the magnet 16b fixed to the spool 2 causes the pair of Hall elements 16a to
If it is determined that the thread is being fed out, the process proceeds to the next step S31, where the up/down counter 17 is
The voltage signal generated from the sensor 16 every rotation of the spool 2 is converted into a pulse signal by the waveform shaping circuit 16c, and this is added to the up/down counter 17 to perform up counting. do. Then, proceeding to the next step S32, the count contents of the up/down counter 17 are taken in, and based on this taken-in count value, the payout yarn length D is calculated by y = a ₁ x ³ + b ₁ x ² + c ₁ x. Execute. In this case, the diameter of the fishing line used is 0.28 mm.

The yarn length D calculated in step S32 is latched in a register (not shown) built into the CPU 11 (step S33). The latched yarn length D is outputted to the yarn length display section 5c in the next step S34, and the calculated yarn length D is thereby digitally displayed on the yarn length display section 5c. When the processing of step S34 is completed, the process returns to step S30 again, and the processing after step S31 is executed, and the display contents of the yarn length display section 5c are changed in the upward direction in accordance with the length of the yarn being let out each time. At this time, the yarn length display section 5
The displayed value of c changes in units of 1 m. When the device lands on the water and the thread payout stops, the thread length display section 5c displays the thread length at the time when the thread payout stops.If this display value is, for example, "50", This indicates that the fishing line has been let out for 50 meters, and at the same time the fishing line has been let out almost from the shore.
It means that it is at 50m.

On the other hand, once the tackle sinks (counts down) to a predetermined water depth after landing on the water, the rod and reel are operated to move the tackle towards the shore. That is, when the handle 9 is rotated to rotate the spool 2 in the winding direction (reverse rotation), the fishing line 3 is moved from the spool 2.
The microcomputer 10 executes a winding processing routine at the same time as the film is sequentially wound.

That is, when the spool 2 is rotated in the winding direction, the rotation and direction are detected by the sensor 16, and by inputting the signal to the microcomputer 10, it is determined that the spool 2 is not being fed out in step S30 of FIG. Then, the process proceeds to step S35, where the up/down counter 17 is set to function as a down counter. And spool 2
By inputting a pulse signal for each rotation into the up/down counter 17, the count value counted when the thread is let out is counted down by -1. In the next step S36, the count content of the up/down counter 17 is taken in, and based on this count content, the calculation y=a ₁ x ³ +b ₁ x ² +c ₁ x is executed to determine the winding yarn length d. Calculate. step
S37 subtracts the winding yarn length d from the unwinding yarn length D, and the result of this subtraction is used in the next step.
In S38, the yarn length D-d is latched in the built-in register of the CPU 11, and the process proceeds to the next step S39 to output the latched yarn length D-d to the yarn length display section 5c. d is digitally displayed on the yarn length display section 5c.

When the process of step S39 is completed, the process proceeds to step S40, and it is determined whether the subtracted value of D−d in step S38 is D−d=2m. That is,
It is determined whether the length of the thread from the tip of the rod to the hook has reached approximately 2 m, and if "NO", the process returns to step S36 and the calculation of the winding thread length d is executed.
When it is determined that the judgment result in step S40 is D-d=2, the process proceeds to step S41, where an alarm drive command is sent to cause the alarm 23 to repeatedly sound "pitsu, pitsu". The angler is alerted that the fishing line 3 that has been let out is reaching its end. At the same time, this prevents the tackle from colliding with the rod tip and breaking the rod tip due to excessive winding of the fishing line 3. That is, the rod tip is protected. When the thread that has been let out is completely wound up, the process proceeds to step S42, where a reset process is executed for the thread length display section 5c. As a result, even if the winding force on the spool 2 changes due to changes in the attractive force of the line, such as when a fish hits the line, the winding diameter of the line changes and an error occurs between the line payout amount and the winding display value. This is eliminated, and the yarn length can always be measured from the zero display state when the yarn is let out. Incidentally, when the latched yarn length is D-d<1, D-d=0 is forcibly set and the process proceeds to step S42.

That is, even if the fishing line 3 is completely wound up, even if the calculation result of (+) or (-) is output to the line length display section 5c due to an error in the amount of reeling out.
By resetting this, the above-mentioned display error can be eliminated for each casting operation.
This means that the length of the unreeled yarn can always be displayed with high accuracy.

In Figure 8, the horizontal axis shows the amount of yarn that is actually wound on the spool (or the amount of yarn that is wound up).
The vertical axis is the spool rotation speed at that time, and it is a characteristic diagram showing the relationship between the thread payout amount and the spool rotation speed as an actual value.The curve is for a thread diameter of 0.28 mm, and the curve is for a thread diameter of 0.30 mm. The curves show those with a thread diameter of 0.35 mm, and constants are set for each thread diameter using the approximate formula for calculating the thread length of y = ax ³ + bx ² + cx (a ₁ ~ a ₃ , b ₁ to _{b 3} ,
c ₁ to c ₃ ) so that the yarn length can be calculated with high accuracy. Here, the constant changes depending on the type of yarn, the diameter (thickness) of the yarn, the elongation rate of the yarn, etc., and is determined by the specifications of the reel. Then, repeated data on unwinding and winding is collected for each thread diameter, and the average value is calculated by taking into account variations in thread tension, thread thickness, etc.

Although the thread length calculation formula based on the spool rotation speed in the above embodiment is determined by a cubic formula, it may be determined by a quadratic formula. In this case, the calculation load on the microcomputer can be reduced. In addition, the input data for the thread diameter is 3
Not limited to types.

(F) Effect of the invention As explained above, according to the invention, a calculation formula suitable for the fishing line diameter is selected for each fishing line diameter, and the line length can be measured and calculated based on this calculation formula. This system improves the accuracy of measuring the length of the yarn being fed out and wound up, allows the same reel to be used for yarns with different diameters, and also issues an alarm when it is determined that the end of the yarn has reached a predetermined amount when winding the yarn. Since this alarm sound can be used to notify the angler that the end of the line is approaching, even if there is an error between the amount of line fed out and the value displayed on the display and the display does not show zero, the angler can still catch the hook. It is possible to prevent the rod tip from breaking due to
