When a predetermined tension is applied to the fishing line, the fishing line is wound around a spool, and when the basic data is obtained from the number of revolutions of the spool, the tension determination means measures the tension applied to the fishing line.
Then, the measurement result is replaced with a previously stored index serving as a tension guideline for winding the fishing line, and the index is displayed on the index display means as a guideline.

According to the second aspect of the invention, when the basic data is obtained from the rotation speed of the spool, the current measuring means measures the drive current value of the spool drive motor, and the measurement result is the index replacing means.

The built-in up / down counter 81 is set to the up-count or down-count state, and the rotation pulse signal of the spool 1 fetched from the sensor 61 is up-counted or down-counted.

Further, as described above, from the sensor 53,

A current measuring circuit 83 for measuring the motor load current value of the motor 7 is connected.

The output interface 77 is also connected to the digital display 17 and the motor drive circuit 87 of the spool drive motor 7 via the decoder 85, and the digital display 17 digitally displays the yarn length. A display unit 17a and a display unit 17b for digitally displaying an index serving as a tension indicator of the fishing line 11 when basic data is input are provided. In addition, reference numeral 89 in the figure denotes a power source arranged on the ship.

Next, FIG. 5 will be described. Figure 5 shows the spool 1 of straight used in the present embodiment, in FIG., D: the fishing line 11 is specified winding level 13 until the wound winding yarn diameter D _o when: bottom diameter of the spool 1 D ₁ : Maximum winding thread diameter of spool 1 H: Groove depth of spool 1 up to specified winding diameter level 13 H _MAX : Groove depth of spool 1 up to maximum winding thread diameter D ₁ These are stored in the ROM 71 in advance. It is stored.

In this embodiment, when the fishing line 11 is wound up to the specified winding diameter level 13, first, as will be described later, the number of revolutions N of the spool 1 up to the winding diameter level 13 is input, and then the fishing line is reached. The winding limit rotational speed N _MAX until 11 reaches the maximum winding thread diameter D ₁ is calculated and regarded as the total rotational speed N _e of the spool 1, and then the microcomputer 6
7 ROM 71 in the stored line length formula ^{_{L = dN a 2 + eN a}} ··· (2) where the, N _a: the actual rotational speed of the spool 1 at the time of feeding or winding of the fishing line 11 d = -πH / N : Constant e = π (D _o + 2HN _e / N): constant N _e : total number of revolutions of the spool 1 up to the maximum winding diameter D ₁ N: spool 1 when the fishing line 11 is wound up to the specified winding diameter level 13 from the rotational speed, feeding yarn length L corresponding to the actual rotational speed N _a of the spool 1
Is calculated. The number of revolutions N and the actual number of revolutions N _a of the spool 1 up to the winding diameter level 13 are respectively counted by the up / down counter 81, and each count value is stored in the RAM 73 of the microcomputer 67. ing.

However, when the number of revolutions N of the spool 1 up to the specified winding diameter level 13 is input as basic data, the angler picks the fishing line 11 with his finger to apply a predetermined tension as described above. When the fishing line 11 is wound around the spool 1, the tension is not stable and the rotation speed N of the spool 1 varies, which impairs the input accuracy of basic data.

Therefore, in this embodiment, in order to eliminate the variation in the rotation speed N of the spool 1, a tension determination means is provided to improve the input accuracy of the basic data. The tension determining means in the present embodiment is a current measuring circuit 83 for measuring the motor load current value of the spool drive motor 7 when the rotation speed N of the spool 1 up to the specified winding diameter level 13 is input.
And a microcomputer 67, which is an index replacing unit that replaces the measurement result of the current measuring circuit 83 with an index that serves as a tension guide when the fishing line is wound, and the index is stored in advance in the microcomputer 67.

That is, the ideal tension when the fishing line 11 is wound around the spool 1 is about 0.5 kg, and as shown in FIG. 6, the spool drive motor when a tension of 0.5 kg is applied to the fishing line 11. The motor load current value I (A; ampere) of No. 7 is in the range of 2A and 3A. Then, as shown in FIG.
The motor load current value I (A) increases as the tension applied to the fishing line 13 increases, and the motor load current value I (A) decreases as the tension applied to the fishing line 13 decreases. Are known.

Therefore, in the present embodiment, as shown in FIG. 4, the current measuring circuit 83 for measuring the motor load current value I (A) is connected to the spool drive motor 7, and the measurement result is input to the input interface 75. It is adapted to be input to the microcomputer 67 via the.

Then, the RO of the microcomputer 67
In M71, the relationship between the index serving as the tension indicator of the fishing line 11 at the time of inputting the basic data and the motor load current value I (A) measured by the current measuring circuit 83, Is stored as data such as
Motor load current value I measured by the current measuring circuit 83
(A) is selected from the above data as an index and replaced, and the index is displayed on the display unit 17b of the digital display 17.

Therefore, when inputting the number of revolutions N of the spool 1 up to the specified winding diameter level 13, for example, a fisherman uses the fishing line 1.
When 1 is strongly pinched and a large tension is applied to the fishing line 11, the motor load current value of the spool drive motor 7 increases, so a large index having a value corresponding to this measurement result is selected and displayed on the display unit 17b. When the angler weakens the force of pinching the fishing line 11, the index displayed on the display unit 17b decreases.

Since the tension is preferably higher than lower, the angler adjusts the force of pinching the fishing line 11 so that the index displayed on the display portion 17b of the digital display 17 indicates 3 to 4 as a guide. If the tension is applied to the fishing line 11, the fishing line 11 is always wound with an ideal tension of about 0.5 kg,
Variations in the spool rotation speed will be eliminated.

This embodiment is configured in this way, and hereinafter, when the fishing line 11 is wound up to the specified winding diameter level 13 and the rotation speed N and the total rotation speed N _e of the spool 1 are input as basic data. Will be described with reference to the flowcharts of FIGS. 7 and 8.

First, the power source 89 is connected and the microcomputer 67 is initialized and placed in the start state. Then, when the mode switch 19 is pressed in such a state (step S1), the microcomputer 67 is set to the spool rotation speed input mode.

Next, one end of the fishing line 11 is tied to the bottom diameter portion of the spool 1, and the fishing line 11 is picked up to apply tension to the fishing line 11, and the spool driving motor is operated by operating the auto switch 25 or the manual switch 27. 7 is operated and the fishing line 11 is sequentially wound up (step S2).

At this time, the motor load current value I (A) of the spool drive motor 7 is measured by the current measuring circuit 83,
The measurement result is sent to the CP via the input interface 75.
It is input to U69 (step S3). And CPU
At 69, the measurement result measured by the current measuring circuit 83 is selected and replaced as an index based on the data stored in the ROM 71, and the index is displayed on the display unit 17b of the digital display 17 (step S4).

Therefore, when the angler exerts a tension on the fishing line 11 by adjusting the force for pinching the fishing line 11 so that the index displayed on the display unit 17b indicates 3 to 4, the fishing line 11 has an ideal tension. It will be wound up on the spool 1 at about 0.5 kg. Since the line guide of the level winder mechanism (not shown) traverses in the width direction of the spool 1 in synchronization with the rotation of the spool 1, the fishing line 11 is
Is evenly wound.

On the other hand, when the spool 1 rotates, the sensor 6
The pulse signal for each rotation of the spool 1 output from the No. 1 is taken into the up / down counter 81 via the input interface 75 and sequentially counted (step S
5).

When the fishing line 11 is wound up to the specified winding diameter level 13, the roller 49 of the specified winding amount detecting device 47 contacts the outer peripheral surface 57 of the winding diameter as shown in FIG. After several turns to the sensor 53
ON signal from the CP via the input interface 75
It is taken in by U69 (step S6). When the ON signal from the sensor 53 is input, the CPU 69 immediately sends a drive stop command for the spool drive motor 7 to the motor drive circuit 87 to stop the spool drive motor 7, so that the winding of the fishing line 11 is stopped. This is the case (step S7).

In this state, when the angler presses the prescribed winding diameter level data write switch 21 (step S8), the count value of the up / down counter 81 is equal to the prescribed winding diameter level 1.
Since the rotation speed N of the spool 1 up to 3 is stored in the RAM 73 (step S9), the constant d is first determined by the expression d = −πH / N by the rotation speed N.

Thus, if the constant d is determined in this way,
H stored in ROM 71 _MAXBased on
= N obtained by modifying the formula of -πH / N_MAX= -ΠH_MAX/ D
From the formula, the fishing line 11 has the maximum winding diameter D₁Winding up to
Limit speed N_MAXIs calculated (step S10).
Then, when the final data writing switch 23 is pressed (step
Up S11), this winding limit speed N_MAXIs spool
Total speed N of 1_eIs stored in the RAM 73,
As a result, the constant e becomes e = π (D_o+ 2HN_e/ N) formula
And the writing of the constants d and e of the yarn length calculation formula (2)
Completed and input of basic data required for yarn length measurement completed
This is the case (step S12).

After that, since the roller 49 is an obstacle in winding the fishing line 11 over the specified winding diameter level 13 onto the spool 1, the screw 55 is loosened and the specified line winding amount detecting device 45 is removed from the control box 15. Then, the mode selector switch 19 is pressed again to set the microcomputer 67 in the spool rotation speed input mode (step S13),
The auto switch 25 or the manual switch 27 is pressed to rewind the fishing line 11 (step S14).

When the spool 1 rotates again in the yarn winding direction, the pulse signal for each rotation of the spool 1 output from the sensor 61 is updated via the input interface 75.
It is taken into the down counter 81 and counting is continued again (step S15). When the fishing line 11 is rewound and the count value N _a of the up / down counter 81 reaches the winding limit rotation speed N _MAX of the spool 1 (step S16), the spool is issued by a command from the CPU 69 which inputs the signal. The drive of the drive motor 7 is stopped and the fishing line 11
The winding of is automatically ended (step S17).

Next, the yarn length measuring operation will be described with reference to the flowchart of FIG. This yarn length measuring operation is described in Japanese Patent Laid-Open No.
This is the same as the yarn length measuring operation in Japanese Patent No. 118839. When the program starts, first, step S1
At 8, it is determined whether or not the fishing line 11 has been delivered. Here, when it is determined that the fishing line 11 is being fed, the spool 1 is rotated in the forward rotation direction along with the feeding of the fishing line 11, so that a signal in the forward rotation direction is output from the sensor 61 via the input interface 75. It is taken in by the CPU 69. As a result, the up / down counter 81 is set in the up direction, and the pulse signal for each rotation of the spool 1 output from the sensor 61 as the spool 1 rotates,
It is taken into the up / down counter 81 via the input interface 75 and sequentially up-counted (step S19).

At the next step S20, the up / down counter 81 is operated at every operation cycle of the microcomputer 67.
Captures the count contents N _a the CPU 69, executes the yarn length calculating the line length formula (2), and outputs the digital display 17 via the output interface 77 and the decoder 85 the result of the calculation, the fishing line 11 The fed-out yarn length L of is displayed digitally on the display unit 17a (step S21).

On the other hand, if it is determined in step S18 that the fishing line 11 has been wound up, the spool 1 is rotated in the reverse rotation direction as the fishing line 11 is wound up, so that a signal in the reverse rotation direction is output from the sensor 61. At the same time as the up / down counter 81 is set to the down direction by being taken in by the CPU 69 via the input interface 75, the pulse signal output from the sensor 61 due to the reverse rotation of the spool 1 is taken in by the up / down counter 81. The down-count operation subtracts from the contents counted at the time of feeding (step S22).

Then, in the next step S23, the count content N _a of the up / down counter 81 is fetched into the CPU 69 at every calculation cycle of the microcomputer 67, and the yarn length calculation formula (2) is calculated to execute the winding yarn. Long, that is,
The yarn length L obtained by subtracting the winding yarn length from the delivered yarn length is calculated, and this is output to the digital display 17 so that the yarn length L is digitally displayed on the display unit 17a (step S23). ).

As described above, in this embodiment, the current measuring circuit 83 for measuring the motor load current value I (A) is connected to the spool drive motor 7, and the microcomputer 67 which inputs the measurement result is connected to the ROM 71. Remembered From such data, the index corresponding to the measurement result is selected and replaced, and the index is displayed on the display unit 17b of the digital display unit 17.
The angler is displayed on the display unit 17b.
If the force for pinching the fishing line 11 is adjusted and tension is applied to the fishing line 11 so that the index displayed in 3 indicates 4, the fishing line 11 can always be wound with an ideal tension of about 0.5 kg. Becomes

Therefore, according to this embodiment, when a predetermined tension is applied to the fishing line 11 and the basic data of the line length measuring device is input, the index of the winding tension is used as a guide for the display unit 17b.
Therefore, the winding tension of the fishing line 11 becomes constant, and the variation in the spool rotation speed is eliminated. As a result, the measurement accuracy of the yarn length measuring device is improved as compared with the conventional case.

Of course, in the present embodiment, the digital display 17
Since the back surface of the display cover 29 is subjected to the antifogging treatment, the display cover 29 is prevented from being fogged, and the angler can surely confirm the display of the liquid crystal 33.

In the above embodiment, in order to eliminate the fogging of the display cover 29, the back surface of the display cover 29 is coated with the anti-fogging coating agent 31 to perform the anti-fogging treatment. However, instead of such a structure, As shown in FIG. 10, the display cover 29 and the liquid crystal 3
The display cover 29 may be subjected to anti-fogging treatment by interposing a transparent plastic plate 91 in the gap between the display cover 29 and the liquid crystal 3, and a moisture-proof material such as silica gel may be provided in the sealed space between the display cover 29 and the liquid crystal 33. It is also possible to enclose the agent or to enclose an inert gas or dry air to perform the antifogging treatment of the display cover 29.

Furthermore, the present applicant previously filed Japanese Patent Application No. 5-701.
No. 73, a bearing in which at least one of the bearings that supports both ends of the spool shaft is integrated with the reel body and is formed to be distorted in accordance with the load force applied to the spool shaft when tension is applied to the fishing line. Disclosed is a fishing line tension measuring device for a fishing reel, which is supported by a supporting member and is equipped with a strain gauge for measuring the tension applied to the fishing line on the bearing supporting member.

Thus, according to such a tension measuring device, when tension is applied to the fishing line, the bearing support member is distorted according to the load force applied to the spool shaft, so the strain gauge attached to this is connected to the bridge. As a result, the resistance value changes and the equilibrium state of the bridge is broken, resulting in a potential difference proportional to the tension of the fishing line between the contacts.

Therefore, on the basis of this potential difference, the data of the index serving as the tension guideline of the fishing line 11 at the time of inputting the basic data and the potential difference are stored in the ROM 71 to input the basic data of the line length measuring device. , The tension applied to the fishing line 11 is measured, and based on the stored data, C
The PU 69 may replace this measurement result with an index serving as a tension indicator and display this on the display unit 17b.

Therefore, according to such an embodiment, the fishing line 1
When a predetermined tension is applied to 1 and the basic data of the line length measuring device is input, the winding tension of the fishing line 11 becomes constant and the variation in the spool rotation speed is eliminated. It is possible to improve the measurement accuracy of the yarn length measuring device.

The present invention is not limited to the yarn length measuring device of the above-described embodiment, and the yarn length measuring device disclosed in Japanese Unexamined Patent Publication (Kokai) No. 2-107908 can be used as a starting point before fishing. Can be applied to all line length measuring devices that wind the line around a spool and measure the line length of the line based on the basic data obtained from the number of revolutions of the spool. It is also possible to apply the present invention to a fishing reel.

In addition, although the tension index is digitally displayed on the display unit 17b in the above embodiment, the display means is not limited to such a structure, and the index display may be an analog type.
