Based on the above, the length of the delivered yarn is calculated and digitally displayed on the display.

[Problems to be solved by the device]

In the conventional fishing reel yarn length measuring device as described above,
Since the winding diameter detection bar member must be constantly in pressure contact with the outer circumference of the fishing line when measuring the length of the delivered line, this pressure contact force restrains the free rotation of the spool when the line is delivered,
In addition to slowing the falling speed of the mechanism, there was a problem that the fishing result was deteriorated.

The present invention solves the above problems,
An object of the present invention is to provide a fishing reel yarn length measuring device capable of measuring the length of fishing line delivered without giving a restraining force to the line delivering rotation of the spool and increasing the tack drop speed.

[Means for Solving the Problems]

A fishing reel line length measuring device according to the present invention is capable of detecting and detecting the rotation of a spool rotatably supported by a reel frame, and detachable from the outer peripheral surface of the fishing line wound on the spool. A bar member that is supported by the reel frame and that detects the winding diameter of the fishing line; and a conversion unit that converts a variation amount corresponding to a change in the winding diameter of the fishing line of the bar member into an electric signal as the fishing line winding diameter. Calculating the reeled-out yarn length based on the spool rotation speed from the rotation detection means and the thread winding diameter data from the conversion means, and calculating coefficients related to the reeled-out thread length based on the reeled-out thread length and the spool rotation speed. No. 1 calculation means, a memory for storing the coefficient calculated by the first calculation means, and the feeding line length of the fishing line is calculated based on the coefficient stored in the memory and the spool rotation speed from the rotation detection means. Second Calculation means, but comprising a display device for displaying a feeding yarn length calculated by the first and second arithmetic means.

[Action]

When the fishing line is fed while the detection bar member is in pressure contact with the outer circumferential surface of the fishing line, the number of rotations of the spool and the line diameter data detected by the detection bar member and the conversion means are taken into the first computing means. The fed-out yarn length is calculated, and these related coefficients are calculated based on the fed-out yarn length and the number of rotations of the spool, and are stored in the memory.

Then, in the actual fishing after the above-mentioned coefficient is calculated, the detection bar member is held away from the outer peripheral surface of the fishing line,
In this state, the fishing line is paid out to lower the tackle, and the length of the fishing line paid out at this time is calculated by the second calculating means based on the number of rotations of the spool and the coefficient.

Therefore, in the present invention, it is not necessary to press the detection bar member against the outer peripheral surface of the fishing line during actual fishing, and the restraint force against the reeling rotation of the spool is lost accordingly. It will be faster and the fishing result can be improved.

And a control circuit for controlling the display drive circuit 35. The control circuit 36 includes a reset switch 22 and a mode switch.
23 is connected.

Next, the operation of this embodiment configured as described above will be described.

When measuring the delivered yarn length L, first, reset switch
22 is pushed to initialize the counter 30, the memory 33, the control circuit 36, and the like. Next, the mode selector switch 23 is pushed to put the control circuit 36 into the line data input mode.

In such a state, the line winding diameter detecting bar 12 is rotated toward the spool 2 side, and its swinging tip end is brought into pressure contact with the outer peripheral edge of the fishing line 4 wound around the spool 2 as shown in FIG. After that, the clutch 5 is released to put the spool 2 in a free state. Then, the fishing line 4 is paid out in the arrow A direction in FIG. 1 by a tackle weight (not shown) connected to the tip of the fishing line 4, and the spool 2 is freely rotated in the arrow B direction. When the spool 2 rotates, the rotation is detected by the magnet 10 and the Hall element 11, and a pulse signal is generated from the Hall element 11 every rotation of the spool, and the pulse signal is counted up by the counter 30. The count value of the counter 30 is fetched by the first arithmetic circuit 32 in every arithmetic cycle of the first arithmetic circuit 32.

On the other hand, the fishing line diameter detection bar 12, which is in pressure contact with the outer peripheral surface of the fishing line 4 wound on the spool 2, rotates clockwise in FIG. Be moved. The change amount of the bobbin diameter due to this rotation is converted into an electric signal by the conversion means 19, and further AD
It is converted into a digital quantity by the converter 31 and input to the first arithmetic circuit 32. In the first arithmetic circuit 32, the counter 30
The fed-out yarn length L is calculated by multiplying the count value taken in from the yarn winding diameter data from the converting means 19. The calculation result of the delivered yarn length L is output to the display device 21 through the display drive circuit 35, and the progressively varied delivered yarn length L is digitally displayed.

Further, in the first arithmetic circuit 32, k = L / N is calculated in a predetermined cycle (this cycle) based on the payout yarn length L calculated by the calculation and the number of revolutions of the spool 2 (count value of the counter 30). Is performed every time the unwinding yarn length L is unwound by 10 m.), And the coefficient k obtained for each calculation is
The average count obtained previously is averaged and stored in the memory 33. That is, the coefficient k is updated every calculation cycle, and this operation is performed until the device is lowered to the predetermined rack position.

When it is visually recognized from the display content of the display device 21 that the device has been lowered to the predetermined shelf position, the clutch 5 is immediately put in and the feeding rotation of the spool 2 is stopped. Then, the mode selector switch 23 is pushed again to bring the control circuit 36 into the normal fishing line length measuring mode.

When the first fishing line payout operation is completed as described above, the bobbin diameter detection bar 12 is rotated in the direction away from the spool 2 and held in a state where it is not in pressure contact with the bobbin winding outer peripheral surface of the spool 2. As a result, the length of the delivered yarn at the time of the lowering operation of the tackle after the second time is measured using the coefficient k and the spool rotation speed N stored in the memory 33 without using the spool diameter data.

That is, the number of rotations of the spool 2 accompanying the feeding of the fishing line 4 is counted by the counter 30 in the same manner as the first time, and
The second arithmetic circuit 34 is operated, and the count value N of the counter 30 is multiplied by the coefficient k of the memory 33 that has taken in each arithmetic cycle to calculate the pay-out yarn length. The calculated yarn length data is output to the display 21 through the display drive circuit 35, and the fed yarn length L is digitally displayed.

Therefore, in the present embodiment, since the line winding diameter detection bar 12 is not pressed against the outer peripheral surface of the line around which the fishing line 5 is wound during the second and subsequent fishing line feeding operations, the free rotation of the spool 2 is restricted by the line winding diameter detection bar 12. Therefore, the falling speed of the device can be made faster than before. Along with this, the fisherman's feeling of frustration due to the slow falling speed as in the past is eliminated, and the fishing result can be improved.

FIG. 3 is a sectional view of an essential part showing another embodiment of the bobbin diameter detecting bar mechanism in the present invention.

In the embodiment of FIG. 3, an operating member 24, one end of which is connected to the converting means 19, is rotatably mounted by being fitted in the support 1a from the outer plate 1c side along the axial direction thereof.
The base of the bobbin diameter detection bar 12 is removably attached to the other end of the operating member 24 with a mounting screw 25.

In such an embodiment, the same effect as in the above embodiment can be obtained, and since the bobbin diameter detection bar 12 can be removed from the reel frame 1, it does not interfere with the reel operation and the reel operation becomes easy. effective.

The method of calculating the coefficient k in the present invention is not limited to the above embodiment.

Further, in the above-described embodiment, the case where the line feeding operation for calculating the coefficient is performed in the fishing ground has been described, but the method of sequentially feeding the fishing line 4 by hand can be similarly performed.

Further, in addition to the coefficient calculation at the time of the yarn feeding operation, the coefficient may be obtained at the time of the yarn winding operation of winding the spool for the yarn length required for fishing.

[Effect of device]

As described above, according to the present invention, the number of revolutions of the spool at the time of delivering the yarn, the length of the delivered yarn calculated from the spool winding diameter data at that time, and the number of revolutions of the spool relate to the number of revolutions of the spool and the length of the delivered yarn. Since the coefficient is obtained in advance, and the actual reeled-out yarn length can be measured from this coefficient and the number of rotations of the spool, the fishing bar member is pressed against the outer peripheral surface of the spool when the fish is caught at a fishing place. There is no need, and the restraining force of the detection bar member with respect to spool free rotation at the time of fishing line operation is eliminated, so that the falling speed of the tackle can be increased and the fishing result can be improved.
