Description

  The present invention relates to a fishing reel provided with a yarn length measuring device for measuring the amount of fishing line fed and the amount of winding from the number of rotations of a spool.

  Many fishing reels have been equipped with a thread length measuring device so that the amount of fishing line fed and wound can be measured and accurate shelves can be taken. In place of the method in which the roller type thread length measuring device is brought into contact with the outer peripheral surface (fishing line winding surface) of the fishing line wound around the spool, a method of measuring the feeding amount and winding amount of the fishing line from the number of rotations of the spool is provided. It has become mainstream.

As such a yarn length measuring device, one disclosed in Patent Document 1 is known.
This thread length measuring device sets a specified winding diameter level below the maximum fishing line diameter of the fishing line on the spool, the spool rotation speed when the fishing line is wound up to the specified winding diameter level, and the winding of the fishing line on the spool. The total number of rotations of the spool from the beginning to the entire length of the spool is counted by an up / down counter, and the constant of the formula for calculating the thread length is determined based on these counted values, and then rotated by feeding and winding the fishing line. Based on the actual rotation speed of the spool, the yarn length is calculated and measured by the yarn length calculation formula, and this is displayed on the display.

Thus, according to the yarn length measuring device, it is possible to measure the feeding amount and the winding amount with high accuracy irrespective of the yarn type (the diameter and material of the fishing line) and the length.
However, since the number of rotations of the spool up to the specified winding diameter level and the total number of rotations of the spool corresponding to the total length of the winding yarn vary depending on the yarn type, the yarn length measuring device of Patent Document 1 changes the yarn type each time. In addition, the fishing line is actually wound around the spool up to the specified winding diameter level and the entire winding length, and the rotation speed and total rotation speed of each spool must be input again. Problems such as the need for a member that recognizes the diameter have been pointed out.

On the other hand, in Patent Document 2, when calculating and measuring the yarn length using the above-described yarn length calculation formula, the number of spool rotations up to a specified winding diameter level and the total number of rotations up to the entire length of the winding yarn are calculated. Prepare a separate table that has been mapped in advance, and each time the thread type is changed, the thread length can be measured by inputting the number of rotations by operating the keys on the operation panel. A measurement device is disclosed.
Japanese Patent No. 2580087 Japanese Patent No. 2601562

  However, in the conventional example of this Patent Document 2, the spool rotational speed up to the specified winding diameter level and the total rotational speed of the spool up to the full length of the winding thread by operating the keys on the operation panel based on the table. Since the number of rotations (numerical values) must be entered, the operation is cumbersome and cumbersome, and it is necessary to carry a table when entering it. If you forget to carry the table, you may not be able to enter accurate data. It was pointed out.

  The present invention has been devised in view of such circumstances, and provides a fishing reel in which the yarn length measurement method based on the above-described yarn length calculation formula is improved and data input associated with yarn length measurement is simplified. With the goal.

  In order to achieve such an object, a fishing reel according to claim 1 includes a spool rotatably supported by the reel body, a rotation detecting means for detecting the rotation speed and rotation direction of the spool, and a yarn length. The thread length calculation formula to be calculated and the spool rotation speed when the fishing line is wound up to the specified winding diameter level set below the maximum fishing line diameter of the fishing line are stored in advance as the thread type, and from the start of winding the fishing line to the spool. Storage means for taking in the total number of rotations of the spool up to the full length of the winding thread, operating means for selecting the spool rotation speed up to the specified winding diameter level related to the thread type mounted on the reel body and stored in the storage means, and the operation means The thread length is calculated from the actual rotation speed of the spool during actual fishing detected by the rotation detecting means based on the thread length calculation formula determined by the spool rotation speed determined in step 1 and the total spool rotation speed up to the entire winding thread length. Operate And calculation means, characterized by comprising a display for displaying the yarn length calculated by the calculating means.

According to the first aspect of the present invention, after selecting the line type of the fishing line to be used by the operating means, the input of the total number of rotations of the spool when all the fishing line is wound on the spool is performed. The basic data input of the yarn length calculation formula accompanying measurement can be performed easily, and there is an advantage that the input operation can be simplified as compared with the conventional case.
In addition, a member for automatically recognizing the specified winding diameter level is not necessary, and it can be configured at low cost.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a fishing reel according to an embodiment of the present invention. In the figure, 1 is a frame, 3 and 5 are side plates attached to the left and right of the frame 1, and the frame 1 and both side plates 3 and 5 A reel body 9 of the fishing reel 7 is formed. A spool shaft is supported between both side plates 3 and 5 via a bearing, and the spool 11 is rotatably supported on the spool shaft.

The spool 11 is rotated by driving a spool drive motor (reference numeral 13 in FIG. 2) or a winding operation of the handle 15 to wind a fishing line. The spool drive motor 13 is a frame in front of the spool 11. 1 is housed in a motor case formed integrally with the motor 1.
A lever-shaped motor output adjuster (hereinafter referred to as a lever-shaped motor output adjuster) that adjusts the motor output of the spool drive motor 13 is provided in front of the upper portion of the side plate 7 on the handle 15 side in the same manner as the electric fishing reel disclosed in Japanese Patent No. 297978. 2 is mounted so as to be rotatable in the same direction as the handle 15, and the microcomputer 21 of FIG. 2 mounted in the control box 19 by the operation of the power lever (operation means) 17 is provided. The motor output of the spool drive motor 13 is continuously increased or decreased from the motor stop state to a high output value via the motor drive circuit 23 to control the winding speed of the spool 11.

Further, as shown in FIG. 1, a clutch lever 25 for operating a clutch mechanism mounted in the side plate 5 is attached between the side plates 3 and 5 behind the spool 11 so as to be pressed downward. With the pressing operation 25, the clutch mechanism is switched from the clutch ON to the clutch OFF.
When the handle 15 is rotated in the winding direction in this clutch OFF state, the clutch mechanism is configured to return to the clutch ON via a known return mechanism, and the clutch ON / OFF switching of this clutch mechanism is configured. Thus, the spool 11 is switched between a winding-up state and a spool-free state so that the power of the spool driving motor 13 and the handle 15 to the spool 11 is transmitted / cut off.

  In FIG. 1, reference numeral 27 denotes a rotation detecting means for detecting the number of rotations of the spool 11 and its rotating direction. The rotation detecting means 27 includes a pair of hall elements 29 mounted on the frame 1 and facing them. The hall element 29 is connected to an input interface 33 of the microcomputer 21 as shown in FIG. Then, the microcomputer 21 takes the rotation pulse signal output from the hall element 29 into the CPU 35 (calculation means), sets the built-in up / down counter 37 to the up-count or down-count state, and takes in the spool Eleven rotation pulse signals are counted.

Then, the CPU 35 calculates the yarn length (feed amount and winding amount) of the fishing line 39 with the yarn length measurement program described below on the basis of the counted value, and the calculation result is used as the operation of the control box 19. A display 43 provided on the panel 41 is displayed via a display drive circuit 45.
As shown in FIG. 1, the control box 19 is attached to the upper part of the reel body 9 with water tightness. A reset switch (operation means) 45, a mode changeover switch (operation means) 47, and a selection input switch (operation means) 49 are provided on the operation panel 41 on the upper surface adjacent to the display device 43. These are connected to a microcomputer 21 as shown in FIG.

  Thus, FIG. 2 shows a configuration diagram of the yarn length measuring device. The microcomputer 21 controls and manages the program memory, the data memory and the input / output device, and calculates and transfers necessary to process a given job. CPU 35 that executes processing, ROM (storage means) 51 that stores an arithmetic processing program and yarn length calculation formulas [1] to [3] described later, and RAM (storage means) that stores data such as calculation results in CPU 35 ) 53, an input interface 33 and an output interface 55, which are connected to the CPU 35 via the bus 57.

As described above, the power lever 17, the Hall element 29, the reset switch 45, the mode changeover switch 47, the selection input switch 49, and the like are connected to the input interface 33. Further, the spool drive motor 13 and the display device 43 are connected to the output interface 55 via the motor drive circuit 23 and the display drive circuit 45.
Thus, in the conventional example of Patent Document 1, as shown in FIG. 3, the relationship between the rotational speed of the spool a and the winding diameter and length of the fishing line b wound around the spool a is set. ,
D: Winding diameter (mm) when the fishing line b is wound up to the specified winding diameter level c
Do: Bottom diameter of spool a (mm)
D1: Total length of the winding line when the fishing line b is wound up to the end (mm)
H: Height from the bottom diameter to the specified winding diameter level c (mm)
Is shown.

In this conventional example, first, the angler winds the fishing line b to the specified winding diameter level c, and inputs the rotation speed N of the spool a up to the winding diameter level c detected by the rotation detecting means to the CPU. When the fishing line b is wound around the spool a to the end, and the total rotation speed Ne of the spool a up to the full length diameter D1 detected by the rotation detecting means is input, the CPU is stored in the ROM of the microcomputer. Yarn length calculation formula L = dNa ² + eNa [1]
L: Yarn length (mm)
Na: Actual number of revolutions of spool a during actual fishing d = −πH / N: constant (2)
e = π (Do + 2HNe / N): constant (3)
Ne: Total number of revolutions of spool a with respect to the total length of the winding thread N: Constants d and e of the number of revolutions of spool a when the fishing line b is wound up to the specified winding diameter level c are calculated by the formula [2], [3] Thereafter, the thread length L is calculated and measured by the thread length calculation formula [1] from the actual rotation speed Na of the spool a during actual fishing detected by the rotation detection means.

However, as described above, every time the thread type is changed, the conventional example is that the fisherman actually winds the fishing line around the spool to the specified winding diameter level and the entire winding length, and the rotation speed and total rotation of each spool. The number had to be entered again, which was very time-consuming.
Further, in the conventional example of the cited document 2, the spool rotational speed up to the specified winding diameter level and the total rotational speed up to the full length of the winding thread according to the thread type are previously mapped in the table, but every time the thread type is changed. In addition, since the number of rotations must be input by key operation based on this table, the operation is cumbersome and troublesome, and it is necessary to carry the table when inputting, and if you forget to carry the table There was a problem that correct data could not be entered.

Therefore, in the present embodiment, in view of such a situation, as shown in FIG. 2, the specified winding diameter level 59 is set to be equal to or less than the maximum winding diameter of the fishing line 39 and the ROM 51 has, for example,
No. 6 nylon thread
No bottom winding (H = 15.0, Do = 20.0) N = 3000
With bottom winding (H1 = 8.0, Ds = 30.0) N1 = 1200
Like
[1] When there is no bottom winding, the spool rotation speed (N) when the fishing line 39 is wound from the bottom diameter (Do) to the specified winding diameter level 59;
[2] When the lower line is wound to the bottom diameter (Ds), the spool rotation speed (N1) when the fishing line 39 is wound from the bottom diameter (Ds) to the specified winding diameter level 59 is
[3] Preset and stored at the factory shipment stage according to the type of yarn to be wound (type: nylon yarn “L” and monochromatic yarn “PE”, number: No. 4, No. 6, No. 8) .

The ROM 51 stores and stores the above-described yarn length calculation formulas [1] to [3].
Then, as shown in FIG. 4, the CPU 35 is configured to sequentially switch to “actual fishing mode”, “thread type selection mode”, and “total rotation speed input mode” by pressing the mode changeover switch 47. In the “actual fishing mode”, the microcomputer 21 counts the rotation pulse signal of the spool 11 taken in from the hall element 29, and calculates and executes the yarn length calculation formula [1] based on the counted value. Is displayed on the display 43. As a precondition for such yarn length measurement, in this embodiment, the constants d and e of the yarn length calculation equation [1] are calculated from the yarn length calculation equations [2] and [3]. Need to be determined.

Therefore, in the present embodiment, when switching to the “thread type selection mode”, as shown in FIG.
・ Displays “Normal (no lower winding)” and “Lower winding (with lower winding)” on the lower winding display 61 of the display unit 43 in two upper and lower stages.
-Display “L” of nylon thread on the type display 63,
・ The number display unit 65 displays the number “6”,
-The cursor 67 of the lower winding display part 61 is made to blink.

Thus, when the angler operates the power lever 17 in the forward / backward direction in such a display state, the cursor 67 is switched alternately between “normal” and “bottom winding”. When the selection input switch 49 is pressed shortly after moving to “normal”, “normal” is selected and determined, and then “L” in the type display section 63 blinks.
When the angler operates the power lever 17 in this state, the display on the type display section 63 is alternately switched between “L” and “PE”, and “L” is blinking. When the selection input switch 49 is pressed briefly, “L” is displayed on the type display section 63 as shown in FIG. 5, the nylon thread to be used is selected and determined, and “PE” is blinking. When the selection input switch 49 is pressed shortly, “PE” is displayed on the type display section 63 as shown in FIG. 6 so that the monochromatic thread to be used is selected and determined.

  Thus, when the type of fishing line is determined in this way, the number “6” of the number display portion 65 blinks. When the angler operates the power lever 17 in this state, The display of the number display section 65 is alternately switched from “6” → “8” → “4”. For example, when the selection input switch 49 is pressed briefly while “6” is flashing, As shown in FIG. 5, “6” is displayed on the number display portion 65, and the number of the fishing line to be used is selected and determined.

In these selections and determinations, the reset switch 45 may be operated when resetting.
When the mode changeover switch 47 is operated after finishing the above operation, the CPU 35 shifts to the “total rotation speed input mode”, and from the basic data stored in the ROM 51,
“The number of revolutions of the spool when the nylon thread 6 is wound from the bottom diameter (Do) to the specified winding diameter level 59 without bottom winding (N)” and “H = 15.0, Do = 20.0” The constant d of the yarn length calculation formula [1] is determined by taking in the yarn length calculation formula [2].

Thereafter, when the fisherman winds up all the fishing lines 39 and operates the selection input switch 49 in the “total number of revolutions input mode”, the CPU 35 calculates the total number of revolutions Ne detected by the rotation detecting means 27 as a thread length calculation formula. After taking in [3] and determining the constant e of the yarn length calculation formula [1], the determined yarn length calculation formula [1] is stored in the RAM 53.
When the thread length calculation formula [1] determined in this way is taken into the RAM 53, the CPU 35 automatically shifts to the “actual fishing mode”, and thereafter, in the “actual fishing mode”, the rotation detecting means 27 The thread length calculation formula [1] is calculated and executed from the actual rotational speed Na of the spool 11 to be detected, and the thread length is displayed on the display unit 43.

When lower bobbin is wound around the spool 11, a gauge or a roller (not shown) is mounted on the reel body 9, and the bobbin is wound until a predetermined bottom diameter (Ds) set and stored in advance is reached. Then, data may be input in the same manner as described above.
Further, as described above, in this embodiment, when the bottom diameter (Ds) in the case of “with underwinding” is set and stored in the ROM 51 in advance, “underwinding” is selected in the “thread type selection mode”. 2, the spool rotation speed (N1) when the fishing line 39 is wound from the bottom diameter (Ds) to the specified winding diameter level 59, and “H1” and “Ds” are the thread length calculation formulas [2], [ 3], for example, a plurality of bottom diameters (Ds1), (Ds2), (Ds3) in the case of “with underwinding”, and spool rotation up to a specified winding diameter level 59 corresponding thereto The numbers (N2), (N3), and (N4) are set and stored in the ROM 51 in advance, and a plurality of bottom diameters (Ds1), (Ds2), and (Ds3) are selected and designated in the reel body. Depending on this selection, selection of selection means, and specification in the case of “with underwinding” Any one of the diameters (Ds1), (Ds2), (Ds3) and the corresponding spool rotational speed (N2), (N3), (N4) are configured to be incorporated into the yarn length calculation formula. Also good.

Since the fishing reel 7 according to the present embodiment is configured in this way, for example, when fishing using No. 6 nylon thread as the fishing line 39 without under winding, the above-described “thread type selection mode”. By following the procedure in, the rotation speed (N) of the spool up to the specified winding diameter level 59 is automatically taken into the yarn length calculation formula [2], and the constant d of the yarn length calculation formula [1] is determined. Is done.
Thereafter, in the “total rotation speed input mode” as described above, if the angler winds up all the fishing lines 39 and operates the selection input switch 49, the CPU 35 determines the total rotation speed Ne up to the entire winding length as the thread length. After taking in the calculation formula [3] and determining the constant e of the yarn length calculation formula [1], the determined yarn length calculation formula [1] is taken into the RAM 53.

When the thread length calculation formula [1] is taken into the RAM 53 in this way, the CPU 35 automatically shifts to the “actual fishing mode”, and thereafter the CPU 35 detects the rotation detecting means in the “actual fishing mode”. The thread length calculation formula [1] is calculated from the actual rotation speed Na of the spool 11 detected at 27 and the thread length is displayed on the display 43.
In addition, although explanation is omitted, for example, when fishing is performed using No. 8 monochromatic thread for the fishing line 39 without under winding, or when fishing is performed using No. 4 nylon thread for the fishing line 39 with under winding, etc. In addition, by following the procedure in the “yarn type selection mode” described above, the rotation speed (N) of the thread type spool up to the specified winding diameter level 59 is automatically taken into the yarn length calculation formula [2]. Thus, the constant d of the yarn length calculation formula [1] is determined.

  As described above, in the present embodiment, the selection of the type of thread to be used and the fishing line 39 on the spool 11 are performed by operating means such as the power lever 17 provided on the reel unit 9, the reset switch 45, the mode changeover switch 47, and the selection input switch 49. By simply inputting the total rotation speed Ne when all the windings are performed, the basic data of the yarn length calculation formula [1] associated with the yarn length measurement can be easily input. Compared to, the input operation can be simplified.
