[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel line length measuring device for measuring the amount of reeling out and winding of fishing line from the number of rotations of a spool.

[0002]

2. Description of the Related Art In recent years, many fishing reels have been equipped with a line length measuring device for measuring and displaying a fishing line payout amount and a winding amount in order to improve fishing results. The device allows the device to be accurately fed to a predetermined shelf. Then, the applicant of the present invention has previously described Japanese Patent Application Laid-Open No. 1-276011 or Japanese Patent Application Laid-Open No. 5-103567.
In Japanese Patent Application Publication No. JP-A-2005-115, a fishing reel line length measuring device capable of measuring a feeding amount and a winding amount of a fishing line from a rotation speed of a spool is disclosed.

[0003] In the yarn length measuring device disclosed in Japanese Patent Application Laid-Open No. 1-276011, the microcomputer has stored in advance in a microcomputer the bottom diameter of the spool and the groove depth up to a specified winding diameter level as a constant corresponding to the spool shape. The basic data corresponding to the thread type is obtained based on the total number of rotations of the spool and the constant when the fishing line is wound up to the specified winding diameter level, and this basic data is stored in the microcomputer together with the actual number of rotations of the spool. The thread length is calculated by inputting the calculated thread length calculation formula and executing the calculation.

In the latter line length measuring device disclosed in Japanese Patent Application Laid-Open No. 5-103567, the groove depth up to a specified winding diameter level set during the winding of the fishing line on the spool and the bottom diameter of the spool is also known. It is stored in the microcomputer in advance as a constant corresponding to the spool shape. Then, the basic data corresponding to the thread type based on the total number of rotations 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 to the end, and the above constants are obtained. Asked,
This basic data is input to a line length calculation formula stored in a microcomputer together with the actual number of rotations of the spool, and the line length is calculated by executing the calculation. The line length measuring device is used to measure the line type of the fishing line. It is now possible to measure the fishing line length regardless of the line diameter).

[0005]

However, in actual fishing, the angler changes the fishing line to a different line type according to the conditions of the fishing spot or the target fish, etc. They may be replaced with spools of different capacities. And if you use different fishing line types,
Usually, a spool in which a fishing line is wound in accordance with a line type is prepared in advance, and these are often replaced by appropriately replacing them.

However, in the above-described conventional yarn length measuring device, the previously stored bottom diameter of the spool and the groove depth up to the specified winding diameter level are constants inherent to the spool incorporated in the reel body. For this reason, it has been pointed out that if the angler replaces the spool with another spool having a different thread winding capacity, a constant unique to the spool differs for each spool, so that accurate measurement of the thread length cannot be performed. .

[0007] Even if a fishing line of a different type is wound on the same spool, each time the type of the line is changed, the total number of rotations of the spool when the fishing line is wound to a specified winding diameter level each time From the constants specific to the spool described above, a constant for each changed fishing line must be newly obtained as basic data and re-inputted to the microcomputer again, and this operation is extremely troublesome.

The present invention has been devised in view of the above circumstances, and has been improved in a line length measuring device of a fishing reel for measuring the amount of reeling out and winding of a fishing line from the number of rotations of a spool. When the angler changes the thread type or replaces with a spool with a different winding capacity according to the situation or target fish, etc., it is only necessary to replace the spool prepared in advance without re-entering the basic data It is an object of the present invention to provide a fishing reel line length measuring device capable of automatically measuring a line length in a fishing reel.

[0009]

In order to achieve the above object, the invention according to claim 1 provides a total rotation of a spool when a fishing line is wound to a certain level and a constant set according to the shape of the spool. The basic data corresponding to the line type determined by the number and the actual number of spool rotations are input to a line length calculation formula stored in a microcomputer, and the calculation is executed. A yarn length measuring device, each spool corresponding to a combination of a spool shape and a yarn type.

The thread length calculation formula is calculated and executed based on the basic data.

[0010]

[0011]

According to the first aspect of the present invention, a fishing line having a different thread type or a spool having a different winding capacity is installed in a reel body in accordance with the condition of a fishing spot or a target fish. When replacing the spool, if the prepared spool is replaced , the discriminating means will be
Which spool corresponding to the basic data you have
Since it is automatically determined whether or not the device is mounted, the basic data corresponding to this is selected from the storage means, and the yarn length calculation formula is calculated based on the basic data.

As described above, in the yarn length measuring apparatus according to the present embodiment, the spool-specific constant and the constant corresponding to the yarn type are used as basic data corresponding to the combination of the spool shape and the yarn type.
OM27 stored in it, the reel body 5, the spool 1,53 ₁ described above, 53 _2, 53 of the _three, the determination means 55 which spool determine mounted on the reel body 5 is mounted ing.

The discriminating means 55 comprises a magnet 57 buried on one side of the spool 1 as shown in FIG. 1, and one magnetic sensor 59 mounted on the frame 21 so as to face the magnet 57. FIGS. 5, 7, 9, and 1
1, the number of the magnets 57 is changed for each of the spools ₁ , 53 ₁ , 53 ₂ and 53 ₃ as shown in FIGS.
It is buried on the same circumference around the spool shaft 3.

The magnetic sensor 59 is connected to the input interface 31 of the microcomputer 23. When the mode changeover switch 38 is operated to set the microcomputer 23 to the discrimination mode, the microcomputer 23 outputs from the magnetic sensor 49. By detecting a detection signal per unit time into the CPU 25, it is possible to quickly determine which of the spools ₁ , 53 ₁ , 53 ₂ , 53 ₃ is mounted on the reel body 5, and to determine the spool shape and the thread according to the spool. The basic data corresponding to the kind combination is read out, and the basic data is inputted to a yarn length calculation formula L = dNa ² + eNa (1) stored in the ROM 27. When the mode is switched to the thread length measurement mode by operating the mode changeover switch 38, the microcomputer 23 determines the forward / reverse rotation of the spool 1 from the above-described equation (1) based on the forward / reverse determination signal output from the magnetic sensor 49. The feeding yarn length L corresponding to the actual rotation speed Na is calculated and measured.

The yarn length measuring device according to the present embodiment is configured as described above. Next, the yarn length measuring operation will be described with reference to the flowchart of FIG. When the angler starts fishing, one of the spools shown in FIGS. 4 to 15 is mounted on the reel body 5 and the microcomputer 23 is set to the discrimination mode by operating the mode changeover switch 38.
When the spool is rotated by operating the manual handle 11,
In step S1, the microcomputer 23 takes in the detection signal from the determination means 55 to quickly determine which spool ₁ , 53 ₁ , 53 ₂ , 53 ₃ is mounted on the reel body 5, The basic data corresponding to the combination of the spool shape and the thread type according to the spool is read, and the basic data is input to the above equation (1).

Therefore, in this discrimination mode, for example, when it is determined that the spool 1 shown in FIG. 4 is mounted on the reel body 5, the bottom diameter D of the spool 1 and the groove depth H up to the specified winding diameter level 17, and The constants d and e corresponding to the fishing line 15 wound on the spool 1 are input to the above equation (1).

Thereafter, the angler switches the mode switch 38.
Is operated to switch to the line length measurement mode, the microcomputer 23 proceeds to step 2 and determines whether or not the fishing line 15 is fed. Here, when it is determined that the fishing line 15 is paid out, the spool 1 is rotated in the normal rotation direction with the feeding of the fishing line 15, and a signal in the normal rotation direction is sent from the magnetic sensor 49 via the input interface 31. Is taken into the CPU 25. Then, while setting the up / down counter 51 in the up direction,
A pulse signal for each rotation of the spool, which is output from the magnetic sensor 49 with the rotation of the spool 1, is taken into the up / down counter 51 via the input interface 31, and is sequentially counted up (step S3).

In the next step S4, the measured value Na of the up / down counter 51 is taken into the CPU 25 at every calculation cycle of the microcomputer 23, and the line length calculation of the above equation (1) is executed. The output interface 33 and the decoder 41
Is displayed on the digital display 39 via (step S5).

In step 6, it is determined whether or not the mode changeover switch 38 has been operated. If it is determined that the mode changeover switch 38 has been operated, the process returns to step 1. If the mode changeover switch 38 has not been operated, step 2 has been performed. And the yarn length measurement is continued. On the other hand, if it is determined in step S2 that the fishing line 15 has been wound, the spool 1
Is rotated in the reverse direction, so that a signal in the reverse direction is output from the magnetic sensor 49 via the input interface 31 to the CP.
U25, thereby setting the up / down counter 51 in the down direction. At the same time, the pulse signal output from the magnetic sensor 49 with the reverse rotation of the spool 1 is taken into the up / down counter 51, and the down-counting operation is performed. Is subtracted from the content counted at the time of feeding (step S7).

Then, in the next step S8, the count value Na of the up / down counter 51 is taken into the CPU 25 at each calculation cycle of the microcomputer 23, and the above equation (1) is calculated and executed. Is calculated by subtracting the winding thread length from the above, and the calculated value is displayed on the digital display 39 (step S9). Then, it is determined in step 10 whether or not the mode switch 38 has been operated. If it is determined that the mode switch 38 has been operated, the process returns to step 1. If the mode switch 38 has not been operated, the process returns to step 2. The yarn length measurement will be continued.

As described above, in the yarn length measuring device according to the present embodiment, the spools ₁ , 53 ₁ , 5 corresponding to the combination of the spool shape and the yarn type are stored in the ROM 27 of the microcomputer 23.
