Description

Detailed Description of the Invention (a) Technical Field of the Invention The present invention relates to a fishing reel such as a casting reel, and more specifically, the present invention relates to a fishing reel such as a casting reel, and more particularly, to a fishing reel that improves the accuracy of measuring the amount of fishing line let out and the amount of reeling, and that improves the accuracy of the fishing line. This relates to a fishing reel that allows adjustment of the total length of the line being turned.

(0) Prior Art and Problems In recent years, fishing reels such as casting reels have been equipped with digital displays that measure the length of the fishing line that is let out from the spool, or the length of the line that is wound onto the spool. Products with added mechanisms are emerging, and
These functions are controlled by a microcomputer.

However, as a method of measuring the amount of fishing line let out and the amount of winding, as shown in Japanese Patent 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 for each 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. Therefore, simply counting the number of pulses per unit length (for example, per 1 m) obtained from the rotation of the spool cannot accurately measure the yarn length, and if the wire diameter of the yarn used changes, the unwinding and winding Since the rate of change in the winding diameter of the thread varies over time, the measuring method described above has the disadvantage that it is not possible to measure the amount of thread unwinding and winding with high precision according to the thread diameter. If the fishing line that has been let out is cut off midway due to it becoming entangled in a rocky reef zone, the numerical value on the display will not be zero even if the remaining line is wound up, and the amount of line that will be let out next time will be incorrect. The value displayed is the sum of the amount of yarn being cut and the amount of yarn being let out, and there is a problem in that it is impossible to accurately grasp and display the amount of yarn being let out.

(C) Purpose of the Invention The present invention solves the above-mentioned conventional problems.The purpose of the present invention is to improve the accuracy of measuring the length of the fishing line and the amount of winding, and to prevent the fishing line from being cut midway. To provide a fishing reel which automatically corrects the total length of the line to a value obtained by subtracting the length of the line to be cut, and can accurately grasp and display the amount of line let out.

B) Structure of the Invention For this purpose, the fishing reel of the present invention includes a reel body, a spool rotatably supported by the reel body and around which a fishing line is wound, a sensor for detecting the rotation of the spool, and a spool rotatably supported by the reel body and around which a fishing line is wound. The signal from the sensor is counted and amplified to count the number of revolutions of the spool when the yarn is paid out.The up/down counter counts down based on the signal from the sensor, and the length of the yarn to be paid out is determined based on the count value of this up/down counter. and a means for calculating the winding line length, a display section for displaying the measured and calculated line length, and various line length calculation formulas stored in memory corresponding to the diameter of the fishing line wound on the spool. means for forcibly resetting the display section and the up/down counter to zero at the end of the winding of the unreeled fishing line; and a means for automatically correcting the total length of the fishing line to a value obtained by subtracting the cut length.

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 arithmetic processing results in the CPU II are stored in the RAM 13, or output port 1
5 and is output to the display unit 5.

The input port 14 of the microcomputer 10 has
The microcomputer 10 is set to thread diameter input mode,
A mode changeover switch 18 for switching between the total yarn length input mode and measurement mode, and a cent switch 1 for inputting the yarn diameter and total yarn length, and correcting the total yarn length.
9 is connected to an on/off mode switch 21 that resets the yarn length display to zero in the total yarn length input mode and measurement mode, and controls the center switch 20 and the internal circuits of the microcomputer 10 on and off. Switches 18 to 21 are arranged on the keyboard 6. Additionally, the output port 15 has an alarm drive circuit 2.
2 is connected to the drive circuit 22, and an alarm 23 is connected to the drive circuit 22.

The above-mentioned alarm 23 is used as a reference sound for counting down after landing on the water and timing the pulling of the device after sinking. 24 is a power source.

FIG. 4 shows the procedure of the mode switching means by operating the mode selection switch 18, FIG. 5 shows the procedure of the yarn diameter input means, and FIG. 6 shows the procedure of the total yarn length input means. Further, FIG. 7 shows the procedure of the yarn length measuring means, and FIG. 8 shows the procedure of the total yarn length correcting means, and programs corresponding to these procedures are stored in the ROM 12 of the microcomputer 10. .

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 selector switch 18 is operated intermittently and sequentially in this state, the microcomputer 10 is activated in step S in FIG.
The mode is sequentially switched to a yarn diameter input mode indicated by 1, a total yarn length input mode indicated by step S2, and a yarn length measurement mode indicated by step S3.

Steps S1 to S3, which are not 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. Then turn it on again.
When the off-mode switch 21 is pressed, the mode is returned to one of the normal modes before the off-mode.

When the microcomputer 10 is set to the thread diameter input mode, the rLINE on the display section 5
J5a lights up or flashes to indicate that it is the thread diameter input mode. At the same time, it is enabled to specify the thread diameter, and Sesothos Isochi 19
The thread diameter input processing routine shown in FIG. 5 can be executed by repeating the ON operation.

In the yarn diameter input processing routine shown in FIG.
When the cent switch 19 is repeatedly turned on, step 5IO-312 and step S13 to
315 and steps 316 to 318 are executed cyclically, for example, with three types of thread diameters of 0.28 mm and 0.30 mm.
The display of mm and 0.35 mm and the corresponding thread length calculation formula are set.

First, when the cent switch 19 is turned on for the first time, the display section 5a and the selected yarn length calculation formula are reset in step 510, and then the yarn diameter of 0°28 mm shown in step Sll is reset. Display processing is executed. That is, the data of thread diameter 0.2B+wm is stored in ROM1.
2 and the data is read from output port 1.
5 to the display section 5, and the thread diameter display section 5bC
Display the numerical value r, 28J. And the next step S
12, a calculation formula y = a1 x' + b1 suitable for measuring the length of the yarn for unwinding and winding with a yarn diameter of 0.28n + m
x2+cIX (y: yarn length, X varnish spool rotation speed)
and at the same time set the constants al+ b1 of the first to third order terms.
Set +C7. This constant a1 + bl + "4
is suitable for yarn length measurement according to the diameter of one roll of tension with a yarn diameter of 0.2 El + lle, and these constants and cubic equations are RO
Stored in MI2. And set switch 19
If the ON operation is completed in one go, the thread diameter of 0.28 mm and its thread length calculation formula will be selected.

Further, if the set switch 19 is pressed once more, the process advances to step 513, where the display of ", 28" on the display section 5b that was set when the cent switch 19 was operated for the first time is reset, and the corresponding The yarn length calculation formula will also be reset. Then, proceed to the next step S14,
Display processing for a thread diameter of 0.30o++m is executed. That is, by reading the data of the thread diameter 0.30+am from the ROM 12 and outputting it to the display unit 5 through the output port 15, the numerical value r, 30J is displayed on the sheep thread diameter display unit 5b.

Next, proceed to step 81.5, and thread diameter 0.30+w
Set the calculation formula y=a2
At the same time, the constant 22 of the first to third order terms, ')2 + 02
Set.

Furthermore, if you press the set switch 19 again, step 3
Proceeding to step 16, the display and calculation formula set at the second time are reset in the same manner as above, and the process proceeds to the next step 317, where a thread diameter of 0.35 mm is displayed. When this thread diameter display process is completed, the process proceeds to step 31B, where the thread diameter is 0.3.
Set the calculation formula y=a2
At the same time, constant 83 for the first to third order terms. b2. Set C3.

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 cent switch 19, the formula for calculating the line diameter displayed on the display section 5b changes to the cent. 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 full thread length input mode by operating the mode changeover switch 18, rCAP and J5d on the display section 5 are lit to indicate that the full thread length input mode is selected.
A process of storing 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 320 in the figure is executed. That is, the maximum display value of the yarn length display section 5C in this embodiment is r199J (unit: meters), and corresponding data previously written in the ROM 12 is written to the RAM 13 by the CPU II. The enlarged numerical data is output port 15
is output to the thread length display section 5c through the thread length display section 5c, and r 1"99 J is displayed on the thread length display section 5c.Next, the process proceeds to step 321, and it is determined whether or not the cent switch 19 has been pressed.The result of this determination is rYEsJ, i.e. cent switch 19
When is pressed once, the process moves to step 322, the switch signal is taken into the CP'U11 through the input port 14, and subtraction of 199-1 is executed. This allows R.A.
The numerical content stored in M13 is counted down by 11, and at the same time, 199-1=198 is displayed on the yarn length display section 5C (step 523).

Thereafter, if the cent switch 19 is intermittently turned on in the same manner, the contents in the RAM 13 will be counted down one by one, and the contents displayed on the yarn length display section 5c will also be changed from 198 to 197-.
-... It will change in decrements to -0.

Therefore, the value displayed on the thread length display section 5C is a value corresponding to the actual length of the gold thread wound around the spool 2, for example r 130 J.
'm, if the on/off operation of the set switch 19 is stopped, 130 m will be set in the RAMI 3 as the actual gold thread length data. Then, when the reset switch 20 is turned on, the yarn length value being displayed becomes zero.

Note that if you set it so that when 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, then this free-running pulse and one pulse of the cent switch 19 will be generated. In combination with the 1 pulse signal for each time, the total yarn length can be set more quickly.

Ru.

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.

During actual fishing, step Sl in FIG.

After passing through S2, the mode changeover switch 1B is operated to set the microcomputer 10 to the yarn length measurement mode. As a result, r'DIST and J5e on the display section 5 are lit to indicate that the yarn length measurement mode is in effect.

In this state, by swinging down the fishing rod (not shown) on which the reel body 1 is attached, a device (not shown) connected to the fishing line at the tip of the rod is thrown into the point, and the device flies to the point. At the same time, the fishing line 3 wound around the spool 2 is let out one after another, and at the same time the spool 2
is rotated in the yarn unwinding direction. This direction of rotation is defined as forward rotation.

When the measurement processing program is thereby started, first, in step S3'0, it is determined whether or not the yarn is being let out. This is magnet 16 fixed to spool 2
This is determined by which of the pair of Hall elements 16a the magnetic field b crosses first, and if it is determined that the thread is being fed out, the process proceeds to the next step 531, where the up/down
The down counter 17 is set to perform an up-count operation, and the voltage signal generated from the sensor 16 every rotation of the spool 201 is converted into a pulse signal by the waveform shaping circuit 16C, and this is added to the up/down counter 17 to generate an amplifier. Count. And next step 3
32, the count contents of the up/down counter 17 are fetched, and based on the fetched count values, y=a, x
3+bl x2+cIX calculates the length of the let-out yarn. It is assumed that the diameter of the fishing line used at this time is 0.28n+m.

The yarn length calculated in step S32 is latched in a register (not shown) built into the CPU 11 (step 533).
). The latched yarn length is outputted to the yarn length display section 5G in the next step 534, and the calculated yarn length is thereby digitally displayed on the yarn length display section 5C. When the process of step S34 is completed, step S34 is completed again.
Returning to step 30, the processes after step 331 are executed, and the display contents of the yarn length display section 5C are changed each time in the upward direction according to the length of the unreeled yarn. At this time, the numerical value displayed on the yarn length display section 5G changes in units of 1 m.

Then, 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, and this display value is, for example, "50".
If so, it means that the fishing line has been let out for 50 m, and at the same time, it means that the bait casting point is approximately 50 m from the shore.

On the other hand, when 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 sequentially wound onto the spool 2, and at the same time, the computer 10 starts the winding processing routine. will be executed.

That is, when the spool 2 is rotated in the winding direction, the rotation and direction are detected by the sensor 16, and by taking in the signal into the microcomputer 10, step 530 in FIG. Proceeding to S35, the up/down counter 17 is set to function as a down counter. and,
By inputting a pulse signal for each revolution of the spool 2 to 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 contents of the up/down force unc 17 are taken in, and based on this count contents, y=a1 x3
By executing the calculation +b1 x2 +c1 x, the winding yarn length d is calculated. Step S'37 is to subtract the winding yarn length d from the unwinding yarn length,
This subtraction result is sent to the next step 538, where the CPU
The yarn length 1)-d is launched into the built-in register of II, and the process proceeds to the next step S39, where the latched yarn length 1)-d is stored in the yarn length table.
The process of outputting to the receiving section 5c is executed, and thereby the calculated yarn length D-d is displayed on the yarn length display section 5C.

When the process of step S39 is completed, step S4
0, and the subtracted value of D-d at step 538 is D-d.
=2m.

That is, it is determined whether the length of the thread from the rod tip to the tackle is approximately 2 m, and if rNOJ, the process returns to step S3.
Returning to step 6, the winding yarn length d is calculated. When it is determined that the determination result in step S40 is D-d=2, the process proceeds to step S41, and an alarm drive command is sent to cause the alarm 23 to repeatedly sound like "pi-hapiso". , alerts the angler 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. In other words, the rod tip is protected. When the thread that has been let out is completely wound up, the process proceeds to step S42, and a reset process is executed for the thread length display section 5C. As a result, the winding force on the spool 2 changes due to a change in the gravitational force of the line, such as when a fish tips it, and the winding diameter of the line changes, causing an error between the amount of line let out and the winding display value. However, this problem can be eliminated, and the yarn length can always be measured from the zero display state when the yarn is let out. Note that when the latched yarn length is D-d<1, D-d=
0, and the process proceeds to step S42.

In other words, even if the fishing line 3 is completely wound up, a (+) or (-) calculation result is output on the line length display section 5C due to an error in the amount of reeling out, it must be reset. Therefore, the above-mentioned display error can be reduced for each casting operation. This means that the length of the line to be fed out can always be displayed with high accuracy.

Next, referring to FIG. 8, the operation for correcting the total yarn length when the yarn that has been let out is cut midway will be described.

In FIG. 8, step S50 is a processing routine for winding up the thread that has been let out, and steps S3.5 to S3.5 in FIG.
This corresponds to S39.

Here, when the thread to be paid out is wound by the winding rotation of the spool 2 by operating the handle 9, and the processing routine of step S50 is being executed, the tackle gets caught on a rocky reef zone or the like and becomes entangled. Suppose that when the fishing line was forcibly pulled in an attempt to remove it, the line was cut in the middle, and when the remaining line was wound up, r 20 J and m were displayed on the line length display section 5C. .

Next, the winding rotation of the spool 2 is stopped, and the center switch 19 is turned on. Then, step S5
1, it is determined whether the set switch 19 has been turned on. If the determination result is YES, the process moves to the next step 352, where the cut yarn is cut from the total yarn length L (130 m) already stored in the memory (RAM) to the value displayed on the display section 5c. Execute the process of subtracting the length l.

For example, if the payout yarn length L1 is 50 m and the value on the display unit 5c of the cut yarn at the end of winding is "20", the cut yarn length β is 20 m, and therefore, in step S52, L-7! The calculation of =130-20=110 is executed and the process proceeds to step S53. In step S53, the data of the total yarn length r130Jm already written in the RAM 13 is
The data is rewritten and corrected as Llolm, and the process proceeds to the next step 354 to display the corrected total yarn length. That is, rl l OJ is displayed on the line length display section 5c, and it blinks to notify the angler that the total line length has been corrected, and after about 2 seconds, the blinking and display are automatically reset. , return to measurement mode and prepare for the next fishing.

In Figure 9, the horizontal axis shows the amount of yarn being let out (or the amount of yarn winding).
This is a characteristic diagram showing the spool rotation on the vertical axis, where the curve ■ is for thread diameters of 0 and 28 mm, the curve ■ is for thread diameters of 0 and 30 mm, and the curve ■ is for thread diameters of 0 and 30 mm. 0.3
The characteristics of these curves are obtained from actual measurement results, and the above-mentioned y=ax3+bx
2+cx was derived so that the above-described characteristic curve can be obtained depending on the yarn diameter.

Although the yarn 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. Moreover, the input data of the thread diameter is not limited to three types.

(f) As described in detail, according to the present 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. , the measurement accuracy of the length of the reeled out and reeled line can be improved, and at the end of the winding of the reeled out fishing line, the amount of reeling is subtracted from the amount of reeling out and the displayed value is automatically multiplied by zero cents. Therefore, even if the unwinding and the winding are repeated, no display error occurs between the two, and the yarn length, especially the unwinding yarn length, can be accurately displayed.

Furthermore, even if the thread is cut in the middle, the total length of the thread can be automatically corrected to a value obtained by subtracting the cut bone, making it possible for the birds to grasp and display the exact amount of thread being drawn out.
