Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for measuring the amount of supply and take-up amount of fishing line, and more particularly, to the size of the diameter of the fishing line wound on the spool, the size of the winding radius of the fishing line on the spool and the fishing line The present invention relates to a fishing line payout amount and a winding amount measuring device capable of accurately measuring a fishing line payout amount and a winding amount regardless of cutting of the fishing line.

2. Description of the Related Art In a fishing reel, it is possible to set a work in progress on a desired shelf by automatically measuring the amount of fishing line or the amount of fishing line and displaying it.
Therefore, conventionally, there has been proposed a fishing line feed-out amount or take-up amount measuring device which rotatably provides a roller in contact with a spool and counts the number of rotations of the roller to calculate the amount of fishing line fed out from the spool. . However, in the contact type device, the fishing line may be entangled with the roller or the arm that rotatably supports the roller. Further, since the roller is always in contact with the spool, the rotation of the spool is resisted by the roller, which hinders the smooth rotation of the spool and prevents the smooth feeding of the fishing line. Further, if the roller slides on the spool contact surface, it is impossible to accurately count the rotation of the roller, which makes it impossible to accurately calculate the amount of fishing line feeding.

In order to overcome the above-mentioned conventional drawbacks, the invention described in Japanese Patent Laid-Open No. 60-244247 proposes a non-contact type fishing line feeding amount and winding amount measuring device.
That is, using the Hall element etc. to detect the number of rotations of the spool,
The feeding amount or winding amount of the fishing line is calculated and displayed by a calculation formula. Specifically, the memory of the microcomputer stores a cubic expression representing the relationship between the amount of fishing line delivered and the number of rotations of the spool for each diameter of the fishing line. The diameter of the fishing line used is stored and the number of rotations of the spool is stored. By detecting and selecting an expression suitable for the diameter of the line, and substituting the number of revolutions into the expression, the amount of feeding of the fishing line is calculated.

Further, in the invention described in Japanese Patent Laid-Open No. 2-107908, a fishing line length measuring device having a roller rotatably supported by an arm and having a roller capable of contacting with a spool is detachably provided on the reel unit, and the fishing line is wound on the spool. In this case, the fishing line length measuring device is attached to the reel unit and the number of rotations of the spool is detected to measure the winding length of the fishing line and store it in the memory. At the time of actual fishing, the fishing line length measuring device is detached from the reel body, and while detecting the number of rotations of the spool accompanying the release of the fishing line, the amount of fishing line feeding out is calculated from the relationship between the fishing line winding length and the number of rotations. .

Further, although the field is different from the fishing reel,
The invention disclosed in Japanese Utility Model Laid-Open No. 58-134711 proposes a detection device that detects the remaining winding amount of a magnetic tape wound concentrically around a rotation axis by using sound waves. That is, ultrasonic waves are oscillated by an ultrasonic oscillator on the wound magnetic tape surface, the sound waves reflected on the tape surface are received by a receiver, and the time difference between oscillation and reception is detected. The presence or absence of remaining tape is detected.

[0006]

However, JP-A-60-
In the invention described in Japanese Patent No. 244247, for example, when a knitted fishing line is used, the diameter of the fishing line is indefinite,
When pressure is applied to the fishing line, the cross section is easily deformed. Therefore, there is a possibility that the fishing line diameter to be stored is not set accurately and an inappropriate formula is selected. Therefore, there is a drawback that an accurate feeding amount and winding amount of the fishing line cannot be obtained. In addition, since a processing procedure of selecting a separate calculation formula for each diameter of the fishing line is required, the contents stored in the memory become complicated, and the calculation processing also takes time,
It is difficult to display the fishing line payout amount and winding amount in real time.

Further, in the invention described in Japanese Patent Application Laid-Open No. 2-107908, when the fishing line is first wound on the spool, the fishing line is still of the contact type, so that the same drawbacks as those of the conventional device described above are expected. Also, the attachment / detachment of the fishing line length measuring device is a troublesome operation. In addition, the amount of rotation when the fishing line is wound on the spool is stored and the amount of line feeding is calculated based on the amount of rotation, so if the fishing line runs out during fishing, the stored contents will no longer be used. It becomes impossible, and there is a drawback that the amount of feeding of the fishing line cannot be calculated.

Further, the invention described in Japanese Utility Model Laid-Open No. 58-1134711 is directed to a magnetic tape wound exactly in a concentric circle, and the fishing reel is a double bearing type reel and a level winding mechanism is provided. However, even if the fishing line is wound uniformly on the spool, the fishing line on the spool is wound in a spiral shape rather roughly as compared with the magnetic tape. Therefore, it is not possible to accurately calculate the amount of fishing line feeding and the amount of winding by simple reflective use of sound waves.

Therefore, the present invention has been made in view of the above problems, and does not cause entanglement of the fishing line or resistance to the rotation of the spool when detecting the number of rotations of the spool, and is accurate regardless of the size of the fishing line diameter. It is possible to measure the payout amount and the take-up amount, it is not necessary to attach and detach the measuring device, and it is possible to accurately measure the payout amount and the take-up amount even after the fishing line is cut. An object is to provide a measuring device.

[0010]

In order to achieve the above-mentioned object, the present invention provides (a) ultrasonic waves of a constant cycle on the outermost peripheral surface of a fishing line wound on a spool rotatably supported by a reel unit. To oscillate the ultrasonic wave, the ultrasonic wave oscillating means fixed at a fixed position of the reel body, and (b) the ultrasonic wave fixed at the fixed position of the reel body and reflected by the outermost peripheral surface are received, Ultrasonic receiving means for outputting, (c) signal detecting means for detecting a signal of a predetermined level or higher among the received signals,
(D) Counting means capable of counting the period from the oscillation of the ultrasonic wave at a constant cycle to the detection of the first received signal at a predetermined level or higher for each constant cycle, and outputting the count value, (e) ) Storage means for storing a coefficient value representing the outermost circumference winding radius of the fishing line corresponding to each of the count values, (f) spool rotation detection means for detecting the rotation of the spool in a non-contact manner, and (g) Each time the count value changes, the coefficient value corresponding to the changed count value is called,
A fishing line feed-out amount and take-up amount measuring device having a calculating means for calculating the feed-out amount or the take-up amount of the fishing line from the relationship with the spool rotation speed, and (h) a display means for displaying the result of the calculation. providing.

[0011]

According to the fishing line pay-out amount and take-up amount measuring apparatus of the present invention having the above-described structure, as the fishing line wound on the spool is unwound, the fishing line winding radius decreases and ultrasonic waves are received. Since the time required to do so also becomes longer, the count value also increases. Here, the count value uniquely corresponds to the winding radius of the fishing line on the spool at the time of counting, and since the storage means stores the coefficient value corresponding to each count value, the spool is set to 1 Each time it rotates, it is judged whether the count value has changed.If the count value has not changed, the current coefficient value is used for calculation, and the total value calculated up to the previous time is added. If there is a change, call the new coefficient value after the change and calculate,
Performs processing to add to the total calculated value up to the previous time. If you store the correspondence between the number of spool rotations and the total calculation amount,
It is possible to instantly display the fishing line winding amount corresponding to the rotation of the spool.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a fishing line feeding amount and winding amount measuring device according to the present invention will be described below with reference to FIGS. FIG. 1 shows a schematic configuration of a fishing line feeding amount and winding amount measuring device according to one embodiment. A fishing line 2 is layered on a spool 1 by a level wind (not shown) capable of reciprocating in the axial direction of the spool. It is wound. A magnet 16 is fixed to the outer surface of the spool 1, and two reed switches 17 and 18 for detecting the rotation of the spool are fixed at a position on the rotation path facing the magnet. The reed switches 17 and 18 are connected to the microcomputer 11.

At a position facing the fishing line wound on the spool 1, an ultrasonic oscillator 4 and an ultrasonic receiver 3 are fixed to a reel main body (not shown) at a distance L2 from the axis of the spool. Ultrasonic waves 12 oscillated from the ultrasonic oscillator 4
Is reflected at the outermost peripheral portion 15 of the fishing line wound on the spool,
The reflected sound wave 13 is configured to be received by the ultrasonic receiver 3. The ultrasonic oscillator 4 is connected to the output gate circuit 6, and the output gate circuit 6 is connected to the microcomputer 11 and the measurement period pulse generating circuit 8 and the carrier oscillator 7 are connected.
It is connected to the. As shown in FIG. 2, the measurement cycle pulse generation circuit 8 is configured to be able to output a cycle pulse waveform a having a measurement cycle width of Ta to the output gate circuit 6.
Further, the carrier oscillator 7 is configured to be able to output the square wave b shown in FIG. 2 to the output gate circuit 6. Here, the oscillation frequency of the square wave b is set near the resonance frequency of the ultrasonic oscillator 4. The output gate circuit 6 is provided so as to periodically output the square wave c for the measurement period width Ta time as shown in FIG. 2 to the ultrasonic oscillator 4. The ultrasonic oscillator 4, the output gate circuit 6, the measurement period pulse generating circuit 8 and the carrier oscillator 7 constitute an ultrasonic oscillator.

The ultrasonic wave receiver 3 serving as an ultrasonic wave receiving means is provided so as to be able to generate a sound wave reception signal, and is connected to the rectifying circuit 9 via the amplifier 5. Therefore, the received signal is output from the amplifier 5 as the amplified received signal d. Rectifier circuit 9
Is capable of outputting the rectified square wave signal e of FIG. 2 in which the negative component of the received signal d is cut. The rising portion of the rectified square wave signal e in FIG. 2 is delayed by the time T from the rising timing of the periodic pulse waveform a. This delay means the time (propagation time difference) until the ultrasonic wave 12 oscillated from the ultrasonic wave oscillator 4 is reflected by the outermost peripheral portion 15 of the fishing line on the spool 1 and reaches the ultrasonic wave receiver 3.

Further, the rectifier circuit 9 is connected to a level detector 10, and the level detector 10 is connected to the microcomputer 1.
Connected to 1. The level detector 10 has a constant level,
For example, it is configured to detect only the waveform of V1 or more in FIG. The detected rectified signal f is configured to be output to the microcomputer 11, and a pulse signal g having defined rising and falling portions is obtained. The rising timing of the pulse signal g is delayed by T ′ from the rising timing of the periodic pulse signal a. This delay is extended from T in the rectangular rectified signal f by the time when the predetermined level V1 is first reached. Such level detector 1
The detection operation by 0 delays the time delay T in the rectified square wave signal e to T ′, which theoretically lacks in accuracy, but it is a special case of the fishing line wound on the spool. Considering the nature, it is rather an essential detection method. That is, the fishing line has a small diameter and is not flat in cross section.
Further, since it is not evenly wound on the spool, the sound wave may be diffusely reflected, and noise may enter the ultrasonic receiver 3. When a sound wave is emitted to the outermost peripheral surface of the wound fishing line, the first rising signal of the rectified rectangular signal e is not always detected due to the peculiarities of the fishing line, and even if it is detected, noise is detected. It is also possible. Therefore, the level detector 10 is provided to detect a square wave of a predetermined level or higher that is not affected by such noise. The rectifier circuit 9 and the level detector 10 constitute signal detecting means.

The microcomputer 11 includes a CPU 25, a counter 20 connected to the CPU 25, a ROM 21,
It has a RAM 23. Counter 20 as counting means
Is configured to start counting when the periodic pulse signal a rises and end counting when the pulse signal g rises, and the count value corresponds to the time difference T ′. Specifically, the time difference T'can be expressed by T '= 2 (L2-L1) / C where C is the speed of sound and L1 is the fishing line winding radius on the spool at that time, and L2 and C are constants. Therefore, T '
It can be seen that the relationship between and L1 uniquely corresponds. That is, the time difference T'corresponds directly to the fishing line winding radius.
A table showing this relationship as shown in FIG. 3 is stored in the ROM 21 which is a storage means. That is, the conversion count representing the fishing line winding radius R (= L1) corresponding to the count value is stored in the ROM 21 as a table.

The ROM 21 also has the above-mentioned predetermined level V1.
Is stored in the level detector 10 and the predetermined level V
1 is output. The ROM 21 further stores the width Ta of the periodic pulse waveform, and is configured to be able to output a signal related to the width Ta to the output gate circuit 6.

The reed switches 17 and 18 are connected to the CPU 25, and the rotation speed of the spool 1 can be stored in the RAM 23. Magnet 16, reed switch 17, 1
8, the RAM 23, and the CPU 25 constitute spool rotation detecting means.

The microcomputer 11 is connected with a display 14 constituted by, for example, a liquid crystal display plate for displaying the amount of fishing line and the amount of winding, and an alarm device 24 such as a shelf mode storage button 22 and a buzzer. The shelf mode storage button 22 is provided, for example, for storing the calculated relationship between the amount of fishing line delivered and the spool rotation speed in the memory section of the RAM 23. Further, the alarm device 24 is configured to issue an alarm, for example, when the fishing line reaches the stored feeding amount.

Next, the procedure for measuring the amount of fishing line delivered in this embodiment will be described with reference to the flow chart shown in FIG. First, the fishing line is fed out in order to set the tackle at a desired water depth. First, initial setting is made in step S1. In the initial setting, the winding radius R (for example, R = R ₁ ) of the initial fishing line wound on the spool 1 is R.
It is called from the lookup table of OM21. That is, the CPU 25 outputs an operation signal to the measurement cycle pulse generation circuit 8 in a state before the spool is rotated before the fishing line payout operation, the cycle pulse waveform a having a cycle width of Ta is sent to the output gate circuit 6, and the carrier wave is generated. The output gate circuit 6 combines the square wave b from the oscillator 7 and outputs an intermittent square wave c having a period width of Ta to the ultrasonic oscillator 4. Therefore, the ultrasonic waves 12 are emitted, reflected by the outermost peripheral surface 15 of the fishing line wound on the spool 1, and received by the ultrasonic receiver 3.
The reception signal d is output. The received signal is amplified by the amplifier 5, the minus component of the received signal is cut by the rectifier circuit 9, and the rectified square signal e is output. Also CPU1
1 outputs a signal for detecting only a square wave having a predetermined level or more to the level detector 10.
In the first rising portion of the rectified square signal e, the signal whose voltage level is V1 or less is cut. The detection signal g is output to the microcomputer 11, the pulse signal g is obtained, and the time difference T ′ described above is counted by the counter 20. Then, the conversion count R ₁ corresponding to T ′ is called. This R ₁ means the radius of the outermost peripheral surface of the wound fishing line before the spool is rotated.

Next, when the fishing line 2 is paid out from the spool 1 by dropping it or the like, the magnet 16 and the reed switch 17,
18, the spool rotation signal is output to the RAM 23,
The first rotation of the spool is RAM in step S2.
23. Then, in step S3, T '
Is changed. That is, when the fishing line 2 is gradually fed out, the fishing line winding radius on the spool decreases, and as a result, the above-mentioned time delay T'changes (becomes longer), but T'by the judgment in step S3.
Is not changed from the initial value (S3: No), the process proceeds to step S4.

In step S4, the latest calculated value 2πR ₁ is added to the integrated value, which means the amount of fishing line delivered up to the previous time. In this step, the integrated value is zero in the initial measurement stage, 0 + 2πR ₁ N, (N = 1) is calculated, and the calculated value is displayed on the display 14. Then, the process proceeds to step S5, and if the fishing line has a setting such as a shelf mode, it is determined whether the fishing line has been fed to that value (whether the target value has been reached). Repeat the process. If the target value has been reached, the measurement process ends.

If it is determined in step S3 that T'changed (S3: Yes), the process proceeds to step S6. For example, if T'changes after the spool 1 has rotated N ₁ times, in step S6 the total number of revolutions (N = N ₁ ) until T'changes is stored in the RAM 23 and then cleared and changed. A process of reading a new R (R = R ₂ ) corresponding to T ′ from the lookup table is performed. After this process, the process returns to step S2 and the same control is repeated. Therefore, according to this control procedure, when the process returns from step S5 to step S2 and reaches step S4, 2πR which is the integrated value up to the previous time
A process of adding 2πR ₂ to ₁ N ₁ is performed, and the amount of fishing line fed out is displayed on the liquid crystal display plate 14 in real time. By repeating such a measurement procedure, for example, if the number of revolutions of the spool until T'changes after the number of revolutions N ₁ is cleared is N _{2 and} the total number of accumulated values is 2
πR ₁ N ₁ + 2πR ₂ N ₂ . When the spool delivery amount reaches the target value, the measurement operation is ended in step S5.

As described above, every time the spool makes one revolution, the process of adding the new feed amount to the integrated value up to the previous time is executed in step S4, and the feed amount of the fishing line is calculated and displayed. , The shelf mode storage button 22 is operated, and the relationship between the spool rotation speed and the fishing line feeding amount is R
The data can be sequentially stored in the AM 23, and the stored data can be used to easily perform fishing in the shelf mode. That is, by operating the shelf mode storage button 22, the calculation result executed in step S4 is stored every time the spool 1 makes one rotation, and the correspondence relationship between the number of rotations of the spool and the amount of line feeding is stored in the RAM 23. The spool rotation speed up to the desired shelf depth is sequentially stored by shifting to step S5 later. By such an operation, it becomes possible to easily drop the tackle to the depth of the rack in the previous fishing. For example, when the total number of revolutions of the spool 1 is detected and the desired number of revolutions is reached, that is, when the desired shelf is reached (at the time when the desired feed amount is reached).
An alarm may be issued from the alarm device 24 to stop the rotation of the spool.

When it is necessary to feed the fishing line beyond the stored amount of feeding the fishing line, the above step S is newly performed.
It is also possible to execute the processing from 1 to S6, add to the already stored integrated value, and display it. Then, by operating the shelf storage button 22, it is possible to update and store the total amount of feeding.

Further, when the fishing line is wound on the spool, the above-mentioned stored data relating to the spool rotation speed and the fishing line feeding amount corresponding to the rotation speed is used, and the corresponding fishing line feeding amount is stored each time the spool rotates in the reverse direction. Called from the data, it is possible to display the current device depth.

The present invention is not limited to the above embodiments, and various modifications and improvements can be made within the scope of the technical matters described in the claims.

[0028]

According to the present invention described in detail above, the following effects can be obtained. (1) The ultrasonic wave propagation time difference T'is detected, the fishing line winding radius R corresponding to the propagation time difference T'is stored in the table as a conversion count, and the conversion count is called to execute the calculation. Therefore, it is possible to accurately calculate the amount of feeding of the fishing line regardless of the diameter of the fishing line and the nonuniformity of the cross section of the fishing line. (2) When detecting the propagation time difference T ', since a signal of a predetermined level or higher is detected as a rising signal, noise is prevented from being detected regardless of the state of the fishing line on the spool or the winding state, and accurate T 'Can be detected. (3) Since the time delay T ′ is measured in non-contact with the fishing line using an ultrasonic oscillator and a receiver, and the rotation of the spool is also detected in the non-contact to calculate the fishing line feeding amount, Does not have the conventional drawback of being entangled with a contact type roller or a roller support member, and does not cause resistance to rotation of the spool due to the roller, so that a smooth spool rotation operation can be achieved, and the falling speed of the tackle is accelerated and fishing is improved. . (4) It is not necessary to attach the fishing line length measuring device to the reel unit when the fishing line is wound around the spool, as in the invention described in Japanese Patent Application Laid-Open No. 2-107908, and it is possible to improve the taste of fishing. . In addition, even if the fishing line is cut during fishing, the amount of fishing line delivered from the location where the line was cut is calculated using the calculation method described in (1), and the entire amount of delivery is calculated by adding it to the amount of fishing before cutting. Can be measured and displayed. (5) The ultrasonic oscillator and the receiver are used to detect not only whether the fishing line is wound on the spool or not.
Since the ultrasonic wave propagation time difference T'is detected and the fishing line winding radius R corresponding to the propagation time difference T'is stored in the table as a conversion coefficient, it is possible to accurately calculate the fishing line feeding amount.
