Description

  The present invention relates to a tension display device, and more particularly, to a tension display device for a dual-bearing reel that displays a tension acting on a fishing line wound around a spool of the dual-bearing reel.

  2. Description of the Related Art A dual-bearing reel having a water depth display device called a counter is conventionally known. In the dual-bearing reel having the water depth display device, the length of the fishing line fed out from the spool is displayed and the water depth of the device is displayed. The yarn length is related to the number of rotations of the spool. When the thickness of the fishing line is different, the relationship between the line length and the rotational speed changes. For this reason, conventionally, an electric reel, which is a dual-bearing reel with a water depth display device, is provided with a function for obtaining a relationship of a fishing line whose relationship between the yarn length and the rotational speed is unknown (see, for example, Patent Document 1). At this time, for example, the angler winds the fishing line around the spool while picking the fishing line with a fingertip and applying tension to the fishing line. If the tension varies when the fishing line is wound around the spool, the rate of increase in the bobbin diameter varies, and the relationship between the thread length and the rotational speed cannot be obtained with high accuracy. For this reason, conventionally, the tension is measured by the load current of the motor, and the measurement result is displayed (for example, see Patent Document 2).

JP 2005-204525 A Japanese Patent No. 2885356

  In the conventional configuration, when the relationship between the yarn length and the number of rotations of the spool is obtained, the tension is detected by the load current of the motor, that is, the torque. For this reason, when the winding diameter increases, the torque (load current) increases according to the winding diameter even if the tension is the same. For this reason, a value larger than the actual tension is displayed, and the tension cannot be displayed with high accuracy. In particular, in the case of a deep groove spool in which the difference between the yarn winding diameter at the start of winding and the yarn winding diameter at the end of winding is large, the rate of change in the yarn winding diameter with respect to the rotational speed is large, so the tension cannot be accurately displayed.

  An object of the present invention is to display a tension with high accuracy when determining the relationship between the yarn length and the number of rotations of a spool.

  The dual bearing reel tension display device according to the first aspect of the present invention is a device that displays the tension acting on the fishing line wound around the spool of the dual bearing reel. The tension display device includes a display, torque detection means, rotation speed detection means, storage means, relationship storage means, readout means, pincushion diameter calculation means, and tension calculation means. The torque detection means detects torque acting on the spool. The rotation speed detection means detects the rotation speed of the spool. The storage means stores in advance the relationship between the reference line length of the reference fishing line and the rotational speed. The relationship storage means obtains the relationship between the line length of the fishing line and the rotation speed of the spool detected by the rotation speed detection means, and stores it in the storage means. The reading means sequentially reads out the reference yarn length corresponding to the number of rotations detected by the number-of-rotations detecting means from the storage means when obtaining the relationship by the relation storing means. The bobbin diameter calculating means sequentially calculates the bobbin diameter from the rotational speed and reference yarn length read by the reading means, and the rotational speed and reference yarn length read previously. The tension calculating means calculates the tension based on the torque detected by the torque detecting means and the calculated bobbin diameter. The tension display device displays tension information corresponding to the tension calculated by the tension calculator on the display.

  In this tension display device, when a fishing line whose relationship between the yarn length and the number of rotations is unknown is wound around the spool, the relationship between the yarn length and the number of rotations can be obtained by the relationship storage means. At this time, the reference line length of the reference fishing line stored in the storage unit is read by the reading unit according to the detected number of rotations. The bobbin diameter calculating means calculates the bobbin diameter from the rotation speed and reference yarn length when read, and the rotation speed and reference yarn length when read before. For example, the yarn length per one rotation of the spool can be calculated by dividing the difference between the reference yarn lengths at the time of reading and the previous reading by the difference in the number of rotations. The bobbin diameter can be calculated by dividing the yarn length per rotation by the circumference ratio. Then, the tension can be calculated by dividing the detected torque by the calculated bobbin diameter. The calculated tension is displayed on the display by the display means. Here, the bobbin diameter corresponding to the number of rotations is calculated using the relationship of the reference fishing line, and the tension that changes according to the bobbin diameter with respect to the torque is calculated and displayed. For this reason, the tension can be accurately displayed when the relationship between the yarn length and the number of rotations of the spool is obtained. If the angler winds the fishing line around the spool with a constant tension by looking at this display, the relationship between the thread length and the number of rotations of the spool can be obtained with high accuracy.

  A tension display device for a dual-bearing reel according to a second aspect of the present invention is the device according to the first aspect, wherein the dual-bearing reel is an electric reel capable of driving a spool by a motor. In this case, the tension can be accurately displayed on the electric reel.

  The dual-bearing reel tension display device according to a third aspect of the present invention is the device according to the second aspect, wherein the torque detecting means detects the torque acting on the spool by the torque acting on the motor. In this case, since the torque acting on the spool is detected by detecting the torque acting on the motor that rotates integrally with the spool, for example, the magnetostrictive element or the like is determined based on data such as the current value flowing through the motor and the duty ratio. The torque acting on the spool can be detected without providing a dedicated torque detecting means.

  A tension display device for a dual-bearing reel according to a fourth aspect is the device according to the second or third aspect, wherein the motor is mounted on the front side of the spool of the electric reel. In this case, the spool can be made deeper than an electric reel in which a motor is disposed in the spool. Even in the case of such a deep groove spool, the thread winding diameter is calculated sequentially, so that the tension can be accurately displayed from the beginning of the winding to the end of the winding.

  The tension display device for a dual-bearing reel according to a fifth aspect of the present invention is the device according to the third or fourth aspect, wherein the torque detecting means detects the torque based on the current value flowing through the motor, and the value of the current flowing through the motor acts on the motor. Since it changes according to the load, it changes according to the torque acting on the motor, and consequently the torque acting on the spool. Here, the torque acting on the spool can be easily detected without providing a separate means for detecting the torque.

  A tension display device for a dual-bearing reel according to a sixth aspect of the present invention is the device according to the fifth aspect, wherein when the relationship is obtained by the relationship storing means, the tension calculated by the tension calculating means is corrected to be low for a predetermined time from the start of acquisition. Correction means are further provided. In the case of an electric reel, a reduction mechanism such as a planetary gear mechanism that reduces the rotation of the motor is usually provided. This deceleration mechanism is filled with a lubricant such as grease. Until the lubricant is warmed, the fluidity of the lubricant is low and the resistance of the lubricant is large. Therefore, the value of the current flowing through the motor for a predetermined time from the start of rotation increases. For this reason, when the torque is detected by the current value, the tension can be displayed with higher accuracy by correcting the tension to be low and eliminating the influence of the lubricant.

  The tension display device for a dual-bearing reel according to a seventh aspect of the present invention is the device according to the first or second aspect, wherein the torque detecting means has a magnetostrictive element provided on the rotating shaft of the spool. In this case, since the torque acting on the spool can be detected with higher accuracy, the tension can be displayed with higher accuracy. In addition, since the torque can be detected regardless of the presence or absence of a motor, even when the relationship between the spool thread length and the number of rotations is obtained by manual winding with a manually wound double-bearing reel and an electric reel having a water depth display device, The tension can be displayed with high accuracy.

  A tension display device for a dual-bearing reel according to an eighth aspect of the invention is the device according to any one of the first to seventh aspects, wherein a line type setting means for setting the type of fishing line, a tension information changing means, Are further provided. The tension information changing means changes the relationship between the tension calculated by the tension calculating means and the tension information according to the type of fishing line set by the thread type setting means. In this case, for example, a multi-line fishing line such as a fishing line (hereinafter referred to as a PE line) knitted with a plurality of polyethylene fibers and a single-line fishing line such as a fluorocarbon fishing line (hereinafter referred to as a fluoro line). Different tensions can be displayed with the same tension information. In the case of PE line, since multiple fibers are knitted, it winds tighter than a single line fishing line, that is, if it does not wind with a large tension, the entire amount of fishing line of a predetermined thickness (number) and a predetermined length is spooled. There is a possibility that it cannot be wound. Even in such a case, by changing the relationship between the tension information and the tension depending on the type of fishing line as described above, the angler only needs to learn one piece of tension information regardless of the type of fishing line. For this reason, the angler can wind the fishing line around the spool with a constant tension only by matching with the displayed single tension information.

  According to the present invention, the bobbin diameter corresponding to the rotational speed is calculated using the relationship of the reference fishing line, and the tension that changes according to the bobbin diameter with respect to the torque is calculated and displayed. For this reason, the tension can be accurately displayed when the relationship between the yarn length and the number of rotations of the spool is obtained. If the angler wraps the fishing line with a constant tension by looking at this display, the relationship between the thread length and the number of rotations of the spool can be obtained with high accuracy.

<Configuration of counter case>
As shown in FIGS. 1 and 2, the counter case 4 is placed on top of the first side plate 7a and the second side plate 7b, and is fixed to the outer side surfaces of the first side plate 7a and the second side plate 7b with screws. . Inside the counter case 4 is housed a display 61 composed of a water depth display liquid crystal display.

The opening 4a is covered with a transparent cover member 4b made of synthetic resin. The display screen of the display 61 has a water depth display area 61a, a stage number display area 61b arranged behind the water depth display area 61a, and a tension display area 61c arranged to the right of the stage number display area 61b. ing.

The In the learning mode and in the speed mode or the tension mode, different tensions are displayed even at the same stage. In the speed mode or the tension mode, the numerical value of the stage is a value close to the tension acting on the fishing line at that time. Further, even in the learning mode, the tension varies depending on the type of fishing line even at the same stage. In this embodiment, normal learning and lower volume learning are described as examples of the learning mode. Normal learning is a learning mode in which the relationship between the number of rotations of one fishing line and the line length is learned.

The operation key unit 62 includes a motor control selection switch SW1, a 0-set switch SW2, and a high-cut switch SW3 arranged side by side. The motor control selection switch SW1 is a switch for selecting either a tension mode for controlling the motor 12 in the constant tension mode or a speed mode for controlling in the constant speed mode. The 0 set switch SW2 is a switch for setting a water depth display value to 0 by arranging a device on the water surface before fishing. The high cut switch SW3 is a switch for setting the water depth display value to 0 by arranging a device on the water surface when the fishing line is cut off in the middle.

<Reel control system configuration>
As shown in FIG. 5, the reel control unit 60 includes, for example, a microcomputer including a CPU, a RAM, a ROM, an I / O interface, and a liquid crystal driving circuit.

  The reel control unit 60 includes an adjustment lever 5, an operation key unit 62, a spool sensor 63, a spool counter 64, a buzzer 65, a motor drive circuit 66, a display 61, a storage unit 67, and other units. The input / output unit is connected. The operation key section 62 has three switches as described above. The spool sensor 63 is provided to detect the rotation speed, rotation direction, and rotation speed of the spool 10. The spool sensor 63 has two magnet detection elements made of, for example, a hall element or a reed switch, which can detect the magnetic force of a magnet (not shown). The rotation direction of the spool 10 can be detected depending on which magnet detection element detects the magnet first. The magnet rotates in conjunction with the rotation of the spool 10. The spool counter 64 counts pulses output from the spool sensor 63. From the output of the spool counter 64, it is possible to detect the number of rotations X of the spool 10 from the beginning of winding and the rotation speed of the spool 10.

  The buzzer 65 is provided for various notifications by a water depth display or the like. The motor driving circuit 66 is provided to drive the motor 12 at a constant speed or a constant tension by pulse width modulation control. The motor drive circuit 66 includes a current detection unit 66 a that detects a current flowing through the motor 12. The current detection unit 66a is an example of a torque sensor. The storage unit 67 is configured by a rewritable nonvolatile memory such as an EEPROM (Electrically Erasable Programmable Read-Only Memory) and a flash memory, for example. As shown in FIG. 6, the storage unit 67 includes a shelf position data storage area 67a, a learning data storage area 67b, a predetermined yarn data storage area 67c, a speed data storage area 67d, a torque data storage area 67e, A tension information storage area 67f and other data storage area 67g are provided.

  The shelf position data storage area 67a stores display data such as the shelf position set when fishing. The learning data storage area 67b stores learning data indicating the relationship between the actual yarn length obtained in the learning mode and the number of rotations of the spool 10. In the predetermined line data storage area 67c, for example, the relationship between the reference line length of a fishing line having a predetermined thickness and length such as No. 6 300m of the PE line and the rotation speed of the spool 10 is stored in advance. This relationship is used when calculating the tension in the learning mode. The upper limit value of the winding speed (rpm) of the spool 10 for each stage number SC is stored in advance in the speed data storage area 67d. In the torque data storage area 67e, an upper limit value of the winding torque (ampere) of the motor 12 for each stage number SC is stored in advance.

  In the speed data storage area 67d, for example, when the stage number SC is 1st speed, the upper limit speed data SS = 257rpm, when 2nd speed is SS = 369rpm, when 3rd speed is SS = 503rpm, when SS is 4th speed, SS When SS = 665 rpm and 5th speed, SS = 1000 rpm is stored. In the torque data storage area 67e, for example, the upper limit torque data TS = 2A when the stage number SC is 1 stage, TS = 3.5A when 2 stages, TS = 5A when 4 stages, 4 stages In the case of TS = 6.5A, TS = 8A is stored in the case of 5 stages. The torque is corrected to the tension according to the bobbin diameter.

  The tension information storage area 67f stores nine levels of tension information 1-9 displayed in the tension display area 61c in the learning mode and ten levels of tension information 0-9 displayed in the speed mode or the tension mode. The The nine-stage tension information displayed in the speed mode or the tension mode is generally the tension actually acting on the fishing line. For example, when the tension information is “1”, the tension is 0.3 kg-1.5 kg, and when the tension information is “9”, the tension is 8.5 kg or more.

  FIG. 12 shows the tension at each stage in the learning mode. In the learning mode, the angler preferably winds the fishing line with a constant tension. At this time, the PE line that is difficult to stretch and the fluoroline that is easy to stretch are not wound with the same tension, but the PE line that is difficult to stretch must be wound with a larger tension than the easily stretchable fluoroline. Therefore, as shown in FIG. 12, even if the tension information is the same depending on the type of fishing line, the tension is different. For example, the tension in the tension information “3” of the PE line is 1.0 kg to 1.4 kg, and the tension of the fluoroline (FL) is 0.5 kg to 0.8 kg. Thus, the angler may wrap the fishing line around the spool 10 so that the tension information becomes “3”, for example, regardless of the type of fishing line during normal learning.

  The other data storage area 67g stores duty ratio data for PWM control and various temporary data. Further, data on the maximum duty ratio and the minimum duty ratio of each torque stage number SC is also stored.

  The reel control unit 60 includes a motor control unit 70 that controls the motor 12 and a display control unit 71 that controls the display 61 as functional configurations realized by software. The display control unit 71 includes a water depth display unit 72 that displays water depth in the water depth display region 61a, and a tension display unit 73 that displays tension in the tension display region 61c. The tension display unit 73 includes a relationship storage unit 74, a reading unit 75, a bobbin diameter calculation unit 76, a tension calculation unit 77, a correction unit 78, a thread type setting unit 79, and a tension information change unit 80. Have. The relationship storage unit 74 obtains the relationship between the line length of the fishing line whose relationship between the line length and the spool rotation speed is unknown and the rotation speed of the spool 10 detected by the spool sensor 63 during normal learning. The yarn length is stored in the learning data storage area 67b of the storage unit 67 in association with the rotational speed.

  When the reading unit 75 obtains the above relationship by the relationship storage unit 74, the reference yarn length (for example, PE line 6 300m) stored in the predetermined yarn data storage area 67c according to the number of rotations detected by the spool sensor 63 is obtained. Are sequentially read from the storage unit 67. The bobbin diameter calculating unit 76 sequentially calculates the bobbin diameter SD1 from the spool rotation speed X1 and the reference yarn length LN1 read by the reading unit 75 and the spool rotation speed X2 and the reference yarn length LN2 read immediately before. . Specifically, by dividing the yarn length (LX1-LX2) obtained by subtracting the previous yarn length LN2 from the yarn length LN1 at the time of reading by the difference in spool rotation speed (X1-X2), The yarn length L is calculated. The yarn winding diameter SD can be calculated by dividing the yarn length L by π.

  The tension calculator 77 calculates the tension T by dividing the torque data TR obtained by the current detector 66a by the obtained bobbin diameter SD. The correcting unit 78 corrects the calculated tension for a predetermined time (for example, 30 seconds) at the beginning of winding. This is because at the start of winding, the viscosity of the grease filled in the planetary gear mechanism 26 (described later) of the spool drive mechanism 13 is high, so that the resistance of the grease is large. For this reason, the correction amount of the calculated tension T is reduced according to the elapsed time t until the influence of the grease decreases after a predetermined time has elapsed since the start of winding. For example, for the first 5 seconds, the tension T is multiplied by the correction coefficient 0.5, and the correction coefficient is increased by 0.1 every 5 seconds. Thereby, the tension T immediately after the start of winding can be suppressed in the display. Note that, immediately after the start of winding, whatever tension T is calculated, for example, tension information “3” may be displayed regardless of the calculated tension T.

  The tension display unit 73 displays tension information corresponding to the calculated or corrected tension T in the tension display area 61 c of the display 61.

  The thread type setting unit 79 is for setting the type of fishing line to be wound around the spool 10 during normal learning. In this embodiment, two types of fishing lines, a PE line and a fluoroline, can be set. The tension information changing unit 80 changes the relationship between the tension calculated by the tension calculating unit 77 and the tension information according to the type of fishing line set by the line type setting unit 79.

  In the normal learning, the relationship between the tension information and the tension is set so that the fishing line may be wound around the spool 10 so that the tension information indicates “3” regardless of the type of the fishing line. In the normal tension learning, the tension information changing unit 80 changes the tension T for the tension information to be displayed according to the relationship shown in FIG. 12, for example, according to the type of fishing line to be wound. Therefore, the PE line has a larger tension than the fluoroline even if the tension information is the same.

  The tension display unit 73 displays tension information corresponding to the calculated or corrected tension T in the tension display area 61 c of the display device 61.

  The display 61, the current detection unit 66a, the spool sensor 63, the storage unit 67, and the tension display unit 73 constitute the dual-bearing reel tension display device 6 of the present invention.

<Spool configuration>
The spool 10 is attached to the spool shaft 14 so as to be integrally rotatable. The spool 10 includes a tubular bobbin trunk 10a, and a large-diameter first flange 10b and a second flange 10c that are integrally formed on both sides of the bobbin trunk 10a. The spool 10 is of a deep groove type in which the diameter of the bobbin trunk 10a is considerably smaller than the diameters of the first flange 10b and the second flange 10c (for example, less than half the diameter). The spool shaft 14 is fixed to the inner peripheral portion of the bobbin trunk 10a by appropriate fixing means such as press fitting.

  The first end of the spool shaft 14 is supported by the first bearing 18a by the spool support portion 17 as described above. The second end (the right end in FIG. 3) of the spool shaft 14 is supported by the second bearing 18b on the second boss portion 8d of the second side cover 8b.

  The spool shaft 14 includes a large diameter portion 14a to which the spool 10 is fixed, a first small diameter portion 14b on the first end side of the large diameter portion 14a, and a second small diameter portion 14c on the second end side of the large diameter portion 14a. ,have. A clutch pin 16a constituting the clutch mechanism 16 is attached through the radial direction on the second small diameter portion 14c side from the spool fixing portion of the large diameter portion 14a.

<Configuration of clutch mechanism and clutch control mechanism>
The clutch mechanism 16 includes a clutch pin 16a and a clutch recess 16b formed in a cross shape along the radial direction on the left end surface of the pinion gear 32 described later in FIG. The pinion gear 32 constitutes the clutch mechanism 16 and the first rotation transmission mechanism 24 described later. The pinion gear 32 moves along the direction of the spool shaft 14 between the clutch-on position shown in FIG. 3 and the clutch-off position on the right side of FIG. 3 from the clutch-on position. At the clutch-on position, the clutch pin 16a engages with the clutch recess 16b, and the rotation of the pinion gear 32 is transmitted to the spool shaft 14, and the clutch mechanism 16 enters the clutch-on state. In this clutch-on state, the pinion gear 32 and the spool shaft 14 can rotate together. In the clutch-off position, the clutch recess 16b is separated from the clutch pin 16a, and the rotation of the pinion gear 32 is not transmitted to the spool shaft 14. For this reason, the clutch mechanism 16 is in a clutch-off state, and the spool 10 can freely rotate.

  The clutch control mechanism 20 swings the clutch mechanism 16 between the clutch-on position indicated by the solid line in FIG. 2 and the clutch-off position indicated by the two-dot chain line in FIG. Switch to.

<Configuration of spool drive mechanism>
The spool drive mechanism 13 drives the spool 10 in the yarn winding direction. Further, a drag force is generated on the spool 10 during winding to prevent the fishing line from being cut. As shown in FIGS. 2 to 4, the spool drive mechanism 13 includes a motor 12, a reverse rotation prohibiting unit 23 that prohibits rotation of the motor 12 in the yarn winding direction, a first rotation transmission mechanism 24, and a second rotation transmission mechanism. 25. The first rotation transmission mechanism 24 decelerates the rotation of the motor 12 and transmits it to the spool 10. The second rotation transmission mechanism 25 increases the rotation of the handle 2 through the first rotation transmission mechanism 24 and transmits it to the spool 10.

  The motor 12 is accommodated in the second connecting member 7d described above. The motor 12 is prohibited from rotating in the yarn feeding direction by a reverse rotation prohibiting portion 23 in the form of a roller clutch.

  The first rotation transmission mechanism 24 has a planetary gear mechanism 26 connected to the output shaft 12 a of the motor 12. The planetary gear mechanism 26 decelerates the rotation of the motor 12 with a reduction ratio in the range of 1/20 to 1/30, and transmits it to the spool 10. The planetary gear mechanism 26 has a first planetary speed reduction mechanism 27 connected to the output shaft 12 a of the motor 12 and a second planetary speed reduction mechanism 28 connected to the first planetary speed reduction mechanism 27. The planetary gear mechanism 26 is housed in a case 40 that is rotatably supported at both ends by the second side plate 7b and the mechanism mounting plate 19. Internal gears of the first planetary speed reduction mechanism 27 and the second planetary speed reduction mechanism 28 are formed on the inner peripheral surface of the case 40. The sun gear of the first planetary reduction mechanism 27 is coupled to the output shaft 12a so as to be integrally rotatable. The sun gear of the second planetary speed reduction mechanism 28 is coupled to the carrier of the first planetary speed reduction mechanism 27 so as to be integrally rotatable. The output of the internal gear formed in the case 40 is transmitted to the spool 10.

  As shown in FIGS. 2 and 3, the first rotation transmission mechanism 24 includes a first gear member 81, a second gear member 82 that meshes with the first gear member 81, and a pinion gear 32 that meshes with the second gear member 82. , Further. The first gear member 81 is formed on the outer periphery of the case 40 of the planetary gear mechanism 26. Therefore, the first gear member 81 can rotate integrally with the internal gear. The first gear member 81 is also meshed with the driven gear 55 of the level wind mechanism 22. The second gear member 82 is disposed between the mechanism mounting plate 19 and the outer surface of the second side plate 7b. The second gear member 82 is an intermediate gear for transmitting the rotation of the first gear member 81 to the pinion gear 32 with its rotational direction aligned. The second gear member 82 is rotatably supported by the mechanism mounting plate 19. The pinion gear 32 is mounted on the second side plate 7b so as to be rotatable around the spool shaft 14 and movable in the axial direction. The pinion gear 32 is controlled by the clutch control mechanism 20 and moves in the axial direction between the clutch-on position and the clutch-off position.

  As shown in FIGS. 2, 3, 4, and 5, the second rotation transmission mechanism 25 includes a handle shaft 30, a drive gear 31, and a third gear member 83. And a drag mechanism 29.

As shown in FIG. 3, the handle shaft 30 is rotatably supported by the second side plate 7b and the first boss portion 8c of the second side cover 8b. A drag washer 37 of a drag mechanism 29 is attached to the handle shaft 30 so as to be integrally rotatable. The handle 2 is coupled to the tip of the handle shaft 30 so as to be integrally rotatable. Further, a ratchet wheel 35 of the first one-way clutch 34 is attached to the handle shaft 30 so as to be integrally rotatable. The ratchet wheel 35 is mounted in a state where movement in the axially inward direction (left side in FIG. 3 ) is restricted. The ratchet wheel 35 is prohibited from rotating in the yarn feeding direction by a ratchet claw (not shown). The base end of the handle shaft 30 is rotatably supported by a bearing (not shown) on the second side plate 7b. The handle shaft 30 is supported by the first boss 8c of the second side cover 8b by a roller-type second one-way clutch 36. The handle shaft 30 is prohibited from rotating in the yarn feeding direction by the first one-way clutch 34. The drag mechanism 29 can be operated by prohibiting the rotation of the handle shaft 30 in the yarn feeding direction. The second one-way clutch 36 quickly prohibits the rotation of the handle shaft 30 in the yarn unwinding direction.

  The drive gear 31 is rotatably mounted on the handle shaft 30. The drive gear 31 is pressed by the drag washer 37. The drive gear 31 is braked for rotation in the yarn feeding direction by the drag mechanism 29. As a result, the rotation of the spool 10 in the yarn unwinding direction is braked.

  The third gear member 83 is provided to transmit the rotation of the handle 2 to the spool 10. The third gear member 83 is coupled to the carrier of the second planetary reduction mechanism 28 so as to be integrally rotatable. The third gear member 83 meshes with the drive gear 31 and transmits the rotation of the handle 2 to the carrier of the second planetary reduction mechanism 28. The rotation transmitted to the carrier is transmitted to the pinion gear 32 via the first gear member 81 and the second gear member 82. The reduction ratio from the third gear member 83 to the second gear member 82 is generally “1”.

  The drag mechanism 29 has a drag washer 37 and a star drag 3 for adjusting the drag force. The drag mechanism 29 is provided to brake the rotation of the spool in the line feeding direction and prevent the fishing line from being cut. The drag mechanism 29 causes the spool 10 to idle in the yarn feeding direction when a force greater than the set drag force acts on the spool 10.

<Configuration of other mechanisms>
As shown in FIG. 3, the casting control mechanism 21 is a mechanism that presses both ends of the spool shaft 14 to brake the spool 10. The casting control mechanism 21 includes a braking cap 51 that is screwed onto the outer peripheral surface of the second boss portion 8d, a first braking plate 52a, and a second braking plate 52b. The second brake plate 52 b is disposed in the spool support portion 17 and contacts the first end of the spool shaft 14. The first brake plate 52 a is disposed in the brake cap 51 and contacts the second end of the spool shaft 14.

  The level wind mechanism 22 includes a screw shaft 53 whose both ends are rotatably supported by the first side plate 7 a and the second side plate 7 b, and a fishing line guide 54 that engages with the screw shaft 53. An intersecting spiral groove 53 a is formed on the outer peripheral surface of the screw shaft 53. A driven gear 55 connected to the spool drive mechanism 13 is attached to the right end of the screw shaft 53 in FIG. The fishing line guide 54 is guided along the axial direction of the screw shaft 53. The fishing line guide 54 engages with the spiral groove 53 a of the screw shaft 53, and reciprocates along the screw shaft 53 by the rotation of the screw shaft 53. As a result, the fishing line is wound on the spool 10 substantially uniformly in conjunction with the rotation of the spool 10 in the line winding direction.

<Control operation of reel control unit>
The control operation of the reel control unit 60 will be described based on the flowcharts shown in FIGS. Note that the flowcharts shown in FIGS. 7 to 11 are examples of the control procedure, and the control procedure of the present invention is not limited to this.

  In the present invention, the yarn length L is calculated utilizing the fact that the relationship between the yarn length Y per spool rotation and the spool rotation speed X can be approximated to a linear line.

  It is assumed that the fishing line whose thickness and total length are unknown is wound around the spool 10 in a layered manner from the bobbin diameter Bmm, and all the fishing lines have been wound by c rotation. Next, when the Smm fishing line is unwound from that state, it is assumed that the spool 10 has rotated d times.

  Now, since the relationship between the spool rotation speed X and the yarn length Y per spool rotation can be defined by a linear line when the spool rotation speed X is taken on the horizontal axis and the thread length per spool rotation is taken on the vertical axis, If the slope is A, it can be expressed by the following formula.

Y = AX + Bπ (1)
The yarn length Y is calculated by obtaining the slope A and the intercept Bπ in the above equation (1).

Specifically, the slope A of the linear straight line can be obtained from the following formula using four data, that is, the feeding length S, the body diameter B, the total spool rotation speed c, and the feeding rotation speed d.

A = 2 (S−Bπd) / d (2c−d)
For example, when the spool 10 has finished winding at 2000 revolutions from the beginning of winding, and when the spool has been rotated 10 m from that, and the spool has rotated 60 revolutions, if the spool diameter of the spool 10 is 30 mm, the slope A of the linear straight line Is as follows.

A = 2 (10000-94.2 * 60) / 60 (2 * 2000-60) (2)
= 0.0368
Then, if an approximated straight line with an inclination A and an intercept Bπ can be determined, the primary line is integrated for each rotation of the spool (area calculation process), for example, the yarn length L1 for each rotation of the spool from the beginning of winding to the end of winding. Find ~ LN. Then, the water depth LX at the spool rotation speed r at the end of winding is set to “0”, and the relationship between the water depth LX (= LN) from the start of winding to the spool rotation speed X and the spool rotation speed X is calculated. For example, it is stored in the learning data storage area 67b in a map format (LX = MAP (X)).

  When the spool 10 is rotated during actual fishing, the thread length LN is read from the map of the storage unit 67 based on the spool rotational speed X detected by the spool sensor 63 at that time, and the water depth (fishing line) is set based on the read thread length LN. The water depth at the tip is displayed on the display 61.

Next, a specific control process performed by the reel controller 60 will be described with reference to the control flowchart of FIG. 7 or later.

When the electric reel is connected to an external power source via the power cord, initialization is performed in step S1 in FIG. 7. In this initial setting, the count value of the spool counter 64 is reset, various variables and flags are reset, the motor control mode is set to the speed mode, and the display mode is set from the top. The mode from the top is a mode for displaying the water depth from the water surface in the water depth display area 61a.

  Next, in step S2, display processing is performed. In the display process, various display processes such as water depth display are performed. Here, in the speed mode, the speed step number operated by the adjustment lever 5 is displayed in the step number display area 61b, and in the tension mode, the tension step number is displayed. In addition, either the speed mode or the tension mode is displayed.

  In step S3, it is determined whether any switch or adjustment lever of the operation key unit 62 has been operated. In step S4, it is determined whether or not the spool 10 is rotating. This determination is made based on the output of the spool sensor 63. In step S5, it is determined whether any other command or input has been made.

  If any switch of the operation key unit 62 or the adjustment lever 5 is operated, the process proceeds from step S3 to step S6 to execute switch input processing. If the rotation of the spool 10 is detected, the process proceeds from step S4 to step S7. In step S7, each operation mode process is executed. If any other command or input is made, the process proceeds from step S5 to step S8 to execute other processes.

In the switch input process of step S6, it is determined whether or not the adjustment lever 5 is pressed in step S11 of FIG. In step S12, it is determined whether or not the motor control selection switch SW1 has been pressed. In step S13, it is determined whether or not the 0 set switch SW2 and the high cut switch SW3 are simultaneously pressed for 2 seconds or longer. In step S14, the multi-switch operation (e.g., 0 set switch SW2 and the short press operation and long press operation of the high breakage switch SW 3, etc.) is equal to or has been made. This long pressing operation enters a learning mode in which the relationship between the length LN of the fishing line wound around the spool 10 and the spool rotation speed X is acquired and stored in the storage unit 67 in the map format (LX = MAP (X)). Operation.

  If it is determined that the adjustment lever 5 has been operated, the process proceeds from step S11 to step S15. In step S15, the step number SC of the adjustment lever 5 is fetched. In step S16, it is determined whether or not the stage number SC of the adjustment lever 5 is “0”. When the number of steps SC of the adjusting lever 5 is “0”, the motor 12 is turned off. When the number SC of the adjustment lever 5 is not “0”, the process proceeds from step S16 to step S18. In step S18, it is determined whether or not the motor control mode is a constant speed mode. When in the constant speed mode, the process proceeds to step S19, the motor 12 is controlled so as to achieve a speed corresponding to the number of stages SC of the adjustment lever 5, and the process proceeds to step S12. When the mode is not the constant speed mode, the process proceeds from step S18 to step S20, the motor 12 is controlled so that the tension acting on the fishing line becomes the tension corresponding to the step number SC of the adjustment lever 5, and the process proceeds to step S12.

  If it is determined that the motor control selection switch SW1 has been operated, the process proceeds from step S12 to step S21. In step S21, it is determined whether or not the constant speed mode is set. If the constant speed mode is set, the process proceeds to step S22 to set the motor control mode to the constant tension mode. This is because the angler attempts to enter the constant tension mode when the motor control selection switch SW1 is pressed during the constant speed mode. Thereby, tension control is performed according to the operation of the adjustment lever 5. When the constant tension mode is set instead of the constant speed mode, the process proceeds from step S21 to step S23, and the motor control mode is set to the constant speed mode. When the processes of step S22 and step S23 are completed, the process proceeds to step S13.

If it is determined that the 0-set switch SW2 and the high-cut switch SW3 are simultaneously pressed for 2 seconds or longer, the process proceeds from step S13 to step S24 where the learning mode is performed. In step S24, it is determined whether the learning mode is normal learning or lower learning according to the angler's switch operation. When the learner enters the learning mode and operates the 0-set switch SW2, the normal learning of step S25 is set. When the angler in place to operate the 0 set switch SW2 at this time operates the motor control selection switch SW1, to operate the 0 set switch SW2, it is set to a lower volume study of the step S26. When these settings are completed, the process proceeds to step S14.

  When another switch input is made, the process proceeds from step S14 to step S27, and another switch input process corresponding to the operated switch input such as setting the current water depth on the shelf is performed, as shown in FIG. Return to the main routine.

  In the normal learning process in step S25, it is determined whether or not a winding start operation has been performed in step S31 in FIG. In the normal learning process, the zero set switch SW2 is used when starting the winding of the fishing line in the normal learning or when ending the winding. If winding has not been started, the process proceeds to step S32, and the type of fishing line is displayed as shown in FIG. As for the type of fishing line, “PE (PE line)” or “FL (fluoro line)” indicating the type of fishing line blinks in the stage number display area 61b. In the water depth display area 61a, “E1 (PE line learning process)” or “E2 (fluoro line learning process)” indicating which type of fishing line is being learned is displayed.

  In step S33, it is determined whether or not the motor control selection switch SW1 has been operated. In the normal learning process, the motor control selection switch SW1 is used to select the type of fishing line. When the motor control selection switch SW1 is operated, the process proceeds from step S33 to step S34. In step S34, if the PE line is displayed in step S32, that is, if the PE line is already set, the process proceeds to step S35. In step S35, the type of fishing line is switched to the fluoroline. If the fluoroline is displayed in step S32, the process proceeds from step S34 to step S36, and the type of fishing line is switched to the PE line. As a result of these switchings, nine levels of tension information during normal learning are set to the tension information of the selected fishing line. When these processes are completed, the process returns to step S31. In step S33, the process returns to step S31 until the motor control selection switch SW1 is operated.

Anglers and selection of the type of fishing line is completed is, by operating the 0 set switch SW 2 to start the winding of the fishing line to the spool 10. When winding of the fishing line is started, the process proceeds from step S31 to step S41. In step S41, a timer for measuring the passage of a predetermined time from the start of learning (for example, 20 seconds to 40 seconds, 30 seconds in this embodiment) is started. This timer is for correcting the tension display at the start of learning to eliminate the influence of the grease charged in the planetary gear mechanism 26. When fishing line winding is started, tension information corresponding to the detected tension is displayed in the tension display area 61c, as shown in FIGS. 13 (b) to 13 (d). A numerical value corresponding to the rotation speed (rotation position) of the spool 10 is displayed in the water depth display area 61a. Here, for example, a numerical value of 1/6 of the actual rotational speed is displayed. Therefore, in FIG. 13C, since the display is 20, it indicates that the spool 10 is actually rotating 120 times. Further, information indicating which type of fishing line is normal learning is displayed in the step number display area 61b. The angler can learn with high accuracy by winding the fishing line with the tension information displayed in the tension display area 61c set to “3”.

In step S42, the spool rotational speed X is increased according to the value of the spool counter 64. For example, when the spool sensor 63 outputs 10 pulses per spool rotation and the spool counter 64 increases by 10 per spool rotation, the spool rotation speed X increases by 1 when the spool counter 64 increases by 10. In step S43, the current value i detected by the current detector 66a is captured. In step S44, the spool rotational speed X is captured. In step S45, the length of the reference fishing line stored in the predetermined thread data storage area 67c of the storage unit 67 at the spool rotation speed X taken in step S44 is read. In step S46, the spool diameter SD1 and the reference yarn length LN1 at the time of reading, and the spool rotation speed X2 and the reference yarn length LN2 that have been read out immediately before, as shown in the processing in the reading unit 75 described above, as shown in the winding diameter SD. Is calculated. At step S47, the calculating the tension T (T = i / S D ) from the calculated line winding diameter SD and the detected current value i. In step S48, it is determined whether or not the timer has expired, that is, whether or not 30 seconds have passed since the fishing line was wound. If the time is not up, the process moves from step S48 to step S49. In step S49, the tension T corresponding to the detected current value is corrected to the corrected tension Tam, and the process proceeds to step S50. For example, for the first 5 seconds, the correction tension Tam is obtained by multiplying the tension T by the correction coefficient 0.5 and increasing the correction coefficient by 0.1 every 5 seconds. As a result, the tension immediately after the start of winding can be suppressed in the display.

If the timer is up, step S49 is skipped and the process proceeds to step S50. At step S50, it is determined whether P E line is selected. When the PE line is set, the process proceeds from step S50 to step S51. In step S51, the tension information corresponding to the tension calculated using the relationship between the tension for the PE line and the tension information among the tension information and the tension shown in FIG. 12 is displayed in the tension display area as shown in FIG. 61c. If the fluoroline is set, the process proceeds from step S50 to step S52. In step S52, the tension information corresponding to the tension calculated using the relation between the tension for the fluoroline and the tension information among the tension information and the tension shown in FIG. 12 is displayed in the tension display area 61c. In this display, the relationship between the tension information and the tension is set so that the optimum tension for normal learning is obtained when the tension information is “3” in any fishing line. For this reason, the angler only needs to wind the fishing line around the spool 10 so that the tension information is always “3” regardless of the type of fishing line in normal learning. When the process of step S51 or step S52 ends, the process proceeds to step S61 of FIG.

  In step S61, it is determined whether or not the winding of the predetermined length of fishing line has been completed. This determination is made by the operation of the 0-set switch SW2 after the angler has finished winding the fishing line. After the winding of the line is completed, for example, a 10m fishing line is fed out to learn the relationship between the spool rotation speed and the thread length per one rotation of the spool. In step S62, it is determined whether or not the 10m feeding has been completed. To do. This determination is also made based on whether or not the 0-set switch SW2 has been operated. When the fishing line is colored differently, for example, every 10 m, the feeding operation can be performed, but depending on the fishing line, the coloring may not be performed. In such a case, a 10-m fishing line may be wound up by tying a 10-m fishing line to the tip. If the fishing line has not been fed out for 10 m, the process returns to step S31 in FIG.

When the yarn winding is completed and the rotation of the spool 10 is stopped, the process proceeds from step S61 to step S63. In step S63, the spool rotational speed X when winding is completed is set to the total spool rotational speed c. In step S64, the spool rotational speed X is decreased in accordance with the fishing line feed. Similarly to step S43, for example, when the spool counter 64 is decremented by 10, the spool rotational speed X is decreased by one.

When the yarn feeding is completed, the process proceeds from step S62 to step S65. In step S65, the spool rotational speed X reduced by the feeding is subtracted from the total spool rotational speed c, and the subtraction value is set to the feeding rotational speed d. This delivery speed d is the number of revolutions of the spool 10 when the 10m fishing line is delivered. In step S 66, the bobbin diameter (= intercept Bπ) and the feeding length S are read from the storage unit 67. These two data are written in the learning data storage area 67b of the storage unit 67 in advance.

  In step S67, the inclination A of the approximate primary line is obtained from the obtained four data c, d, Bπ, S by the above-described equation (2), and the approximate primary line is calculated. Thereby, the relationship between the spool rotation length Y and the spool rotation speed X over the entire length of the fishing line whose diameter and length are unknown is determined. The spool winding diameter SD (Y / π) is obtained by using the spool rotation length Y, and the set torque in the tension mode is corrected by the spool diameter SD so that the tension becomes constant.

  In step S68, the obtained linear straight line is integrated to calculate the relationship between the spool rotational speed X from the beginning of winding to the end of winding and the yarn length LN. Then, the winding end is set to a water depth of 0, and the yarn length LN is converted to the water depth LX. Thereby, the relationship between the spool rotational speed X and the water depth LX is determined.

In step S69 , the obtained relationship between the spool rotational speed X and the water depth LX is stored in the storage unit 67 in a map format, and the process returns to the main routine. As a result, the above-described learning process is executed, and the relationship between the spool rotation speed and the yarn length, which changes depending on the spool diameter, can be corrected by learning only the final portion without learning the entire fishing line. When these processes are completed, the process returns to the switch input routine.

Although detailed explanation is omitted in the lower winding learning process in step S26 of FIG. 8, the same operation as the normal learning process is performed twice for the lower winding thread and the upper winding thread wound around the lower winding thread. At this time, in the lower wound yarn, the tension level is displayed based on the fluoroline, and in the upper wound yarn, the tension level is displayed based on the type of the upper wound yarn. For example, when the PE line is wound on top, the display is changed to a tension level based on the PE line.

The transition of the display screen of the display 61 in this case will be described with reference to FIG. When the angler enters the learning mode and selects the lower volume learning, as shown in FIG. 14A, “-” indicating that the lower volume learning is performed flashes in the stage number display area 61b. Further, information “E3” indicating lower volume learning is displayed in the water depth display area 61a. When the 0 set switch SW2 is operated in this state, the angler starts winding the lower spool. Then, as shown in FIGS. 14B to 14D, tension information corresponding to the detected tension is displayed in the tension display area 61c. The tension information at this time is displayed at a stage based on the fluoroline. Further, “E3” indicating lower volume learning is displayed in the stage number display area 61b. When the fishing people to start winding, tension stage is displayed in the tension display area 6 1c. In addition, a value corresponding to the number of rotations of the spool is displayed in the water depth display area 61a. Also here, a numerical value of 1/6 of the actual rotation speed of the spool 10 is displayed as in the normal learning. When the winding of the lower winding thread is completed, the angler operates the 0 set switch SW2 again to start the operation of winding the upper winding thread to the lower winding thread and winding the fishing line by 10 m. Then, as shown in FIG. 14E, the display of the tension display area 61c disappears and the numerical value of the water depth display area 61a becomes “0”. When the display of the tension display area 61c disappears, the driving of the motor 12 by the adjustment lever 5 is invalid. This point is the same although the screen is not displayed in the normal learning mode. FIG. 14F shows a screen when the angler winds up 10 m of the upper wound thread. Here, the display of the tension display area 61c remains off. When the winding operation of the upper winding thread of 10 m is finished, the angler operates the 0 set switch SW2 again. Then, as shown in FIG. 14 (g) and FIG. 14 (h), the letter “U” indicating the winding operation of the upper winding yarn is displayed in the step number display area 61b, and the tension display area 61c is not a fluoroline but a PE. Tension information is displayed at the stage based on the line. In addition, since the tension information is displayed in this winding operation, the motor 12 can be used. Upon completion of the winding of the first volume yarn, angler, to operate the 0 set switch SW 2 again. This completes the lower volume learning.

  Here, by changing the tension between the lower winding thread and the upper winding thread, the lower winding thread using the easily stretchable nylon line can be wound with a weak tension. For this reason, the malfunction which arises when winding with the same tension | tensile_strength as a PE line can be made hard to produce. That is, when the lower winding yarn that is easy to stretch is wound with the same tension as the upper winding yarn of the PE line that is difficult to stretch, there is a problem that the lower winding diameter becomes small if the length of the lower winding yarn is predetermined. Further, when the lower winding diameter is set in advance, a problem that the yarn length of the lower winding yarn becomes longer occurs. Furthermore, when the lower winding thread is wound with the strong tension of the PE line, the spool may be deformed.

In each operation mode process in step S7 in FIG. 7, it is determined in step S71 in FIG. 11 whether or not the rotation direction of the spool 10 is the yarn feeding direction. This determination is made based on which magnet detection element of the spool sensor 63 has emitted a pulse first. If it is determined that the rotation direction of the spool 10 is the yarn feeding direction, the process proceeds from step S71 to step S72. In step S72, every time the spool rotational speed X decreases, the data stored in the storage unit 67 is read from the spool rotational speed X and the water depth LX is calculated. This water depth LX is displayed in the display process of step S2. In step S73, it is determined whether or not the obtained water depth LX coincides with the bottom position or the shelf position, that is, whether the device has reached the bottom or the shelf. Bottom position or rack position is set in the storage unit 67 by pushing long zero set switch SW 2 when it reaches the tackle injury bottom or shelf. In step S74, it is determined whether or not another mode is selected. If it is not in another mode, each operation mode process is terminated and the process returns to the main routine.

Water depth shifts from step S73 to match the bottom position in Step S 7 5, tackle the buzzer 65 to notify that it has reached the bottom or shelf. In the case of another mode, the process proceeds from step S74 to step S76, and the designated other mode is executed.

When the rotation of the spool 10 is determined to the line winding direction shifts from step S71 to step S 77. In step S77, the data stored in the storage unit 67 is read from the spool rotational speed X, and the water depth LX is calculated. This water depth LX is displayed in the display process of step S2. In step S78, it is determined whether the water depth matches the boat edge stop position. If it has not been wound up to the ship edge stop position, it returns to the main routine. When the ship edge stop position is reached, the process proceeds from step S78 to step S79. In step S79, the buzzer 65 is sounded to notify that the device is on the shore. In step S80, the motor 12 is turned off. As a result, the fish is arranged at a position where it can be easily taken when the fish is caught. This ship edge stop position is set when, for example, the spool 10 is stopped for a predetermined time or less within a water depth of 6 m.

  In the present embodiment having such a configuration, the spool diameter SD corresponding to the spool rotation speed X is calculated using the relationship of the reference fishing line in which the relationship between the spool rotation speed and the thread length is known, and the spool diameter with respect to the torque is calculated. The tension that changes accordingly is calculated and displayed. Therefore, the tension can be accurately displayed when the relationship between the yarn length LN and the spool rotational speed X is obtained. If the angler winds the fishing line with a constant tension by looking at this display, the relationship between the thread length and the spool rotation speed can be obtained with high accuracy.

<Features>
The above embodiment can be expressed as follows.

  (A) The tension display device 6 is a device that displays the tension acting on the fishing line wound around the spool 10 of the dual-bearing reel. The tension display device 6 includes a display 61, a current detection unit 66a serving as torque detection means, a spool sensor 63, a storage unit 67, and a tension display unit 73. The tension display unit 73 includes a relationship storage unit 74, a reading unit 75, a bobbin diameter calculation unit 76, and a tension calculation unit 77. The current detection unit 66 a detects torque that acts on the spool 10. The spool sensor 63 detects the number of rotations of the spool 10. The storage unit 67 stores in advance the relationship between the reference line length of the reference fishing line and the rotational speed. The relationship storage unit 74 obtains the relationship between the line length LN of the fishing line and the spool rotational speed X detected by the rotational speed detection means, and stores it in the storage unit 67. When the relationship storage unit 74 obtains the relationship, the reading unit 75 sequentially reads the reference yarn length corresponding to the spool rotational speed X detected by the spool sensor 63 from the storage unit 67. The bobbin diameter calculation unit 76 sequentially calculates the bobbin diameter SD from the spool rotation speed X1 and the reference yarn length LN1 read by the reading unit 75, and the spool rotation speed X2 and the reference yarn length LN2 read previously. . The tension calculator 77 calculates the tension T from the torque detected by the current detector 66a and the calculated bobbin diameter SD. The tension display device 6 displays tension information corresponding to the tension calculated by the tension calculator 77 on the display 61.

  In the tension display device 6, when a fishing line with an unknown relationship between the yarn length LN and the spool rotation speed X is wound around the spool 10, the relationship storage unit 74 can obtain the relationship between the yarn length LN and the spool rotation speed X. . At this time, the reference section length of the reference fishing line stored in the storage section 67 is read out by the reading section 75 according to the detected spool rotation speed. The spool diameter calculating unit 76 calculates the spool diameter SD from the spool rotation speed X1 and the reference thread length LN1 when read and the spool rotation speed X2 and the reference thread length LN2 when read previously. For example, the difference (LN1−LN2) in the reference yarn length between when read and when read before is divided by the difference (X1−X2) in the spool speed ((LN1−LN2) / (X1−X2)). Thus, the yarn length per one rotation of the spool can be calculated. The spool diameter SD can be calculated by dividing the yarn length per one rotation by the circumference ratio. Then, the tension T can be calculated by dividing the detected torque by the calculated bobbin diameter. Tension information corresponding to the calculated tension is displayed on the display by the display means. Here, the spool diameter corresponding to the spool rotation speed is calculated using the relationship of the reference fishing line whose relation between the spool rotation speed and the thread length is known, and the tension that changes according to the spool diameter is calculated with respect to the torque. Is displayed. For this reason, the tension can be accurately displayed when the relationship between the yarn length and the number of rotations of the spool is obtained. If the angler winds the fishing line around the spool with a constant tension by looking at this display, the relationship between the thread length and the number of rotations of the spool can be obtained with high accuracy.

  (B) In the tension display device 6 for the dual-bearing reel, the dual-bearing reel is an electric reel that can drive the spool by the motor 12. In this case, the tension can be accurately displayed on the electric reel.

(C) In the tension display device 6, the current detector 66 a detects the torque acting on the spool 10 by the torque acting on the motor 12. In this case, since the torque acting on the spool 10 is detected by detecting the torque acting on the motor 12 rotating integrally with the spool 10 , for example, based on data such as the current value flowing through the motor 12 and the duty ratio. The torque acting on the spool can be detected without providing a dedicated torque detecting means such as a magnetostrictive element.

  (D) In the tension display device 6, the motor 12 is mounted on the front side of the spool of the electric reel. In this case, the spool 10 can be made deeper than an electric reel in which a motor is disposed in the spool. Even in the case of such a deep groove spool 10, the thread winding diameter is sequentially calculated, so that the tension can be displayed with high accuracy from the start of the spool winding to the end of the spool winding.

  (E) In the tension display device 6, torque is detected from the value of the current flowing through the motor 12. Since the value of the current flowing through the motor 12 changes according to the load acting on the motor 12, it changes according to the torque acting on the motor 12 and thus the torque acting on the spool 10. Here, the torque acting on the spool 10 can be easily detected without providing a means for detecting the torque separately.

  (F) In the tension display device 6, when the tension display unit 73 obtains a relationship by the relationship storage unit 74, a correction unit that corrects the tension calculated by the tension calculation unit 77 for a predetermined time from the start of acquiring the relationship. 78 is further provided. In the case of an electric reel, a reduction mechanism such as a planetary gear mechanism that reduces the rotation of the motor 12 is usually provided. This deceleration mechanism is filled with a lubricant such as grease. Until the lubricant is warmed, the fluidity of the lubricant is low and the resistance of the lubricant is large. Therefore, the current value flowing through the motor 12 for a predetermined time from the start of rotation increases. For this reason, when the torque is detected by the current value, the tension can be displayed with higher accuracy by correcting the tension to be low and eliminating the influence of the lubricant.

  (G) In the tension display device 6, the torque detecting means has a magnetostrictive element provided on the rotating shaft of the spool. In this case, since the torque acting on the spool can be detected with higher accuracy, the tension can be displayed with higher accuracy. In addition, since the torque can be detected regardless of the presence or absence of a motor, even when the relationship between the spool thread length and the number of rotations is obtained by manual winding with a manually wound double-bearing reel and an electric reel having a water depth display device, The tension can be displayed with high accuracy.

  (H) The tension display device 6 further includes a line type setting unit 79 for setting the type of fishing line and a tension information changing unit 80. The tension information changing unit 80 changes the relationship between the tension calculated by the tension calculating unit 77 and the tension information according to the type of fishing line set by the line type setting unit 79. In this case, for example, different tensions can be displayed with the same tension information for a plurality of fishing lines such as a PE line woven from a plurality of polyethylene fibers and a single fishing line such as a fluorocarbon-made fluoroline. In the case of PE line, since multiple fibers are knitted, it winds tighter than a single line fishing line, that is, if it does not wind with a large tension, the entire amount of fishing line of a predetermined thickness (number) and a predetermined length is spooled. There is a possibility that it cannot be wound. Even in such a case, by changing the relationship between the tension information and the tension depending on the type of fishing line as described above, the angler only needs to learn one piece of tension information regardless of the type of fishing line. For this reason, the angler can wind the fishing line around the spool with a constant tension only by matching with the displayed single tension information.

  (A) In the above embodiment, the present invention has been described by taking an electric reel as an example of a dual-bearing reel, but the present invention is not limited to this. For example, the present invention can be applied to a manually wound double-bearing reel having no motor. In this case, since the torque cannot be detected by the value of the current flowing through the motor, it is necessary to provide a dedicated torque sensor. As the torque sensor, a magnetostrictive element attached to the spool shaft and a coil for reading the output of the magnetostrictive element may be used. The coil is attached to the reel body, for example. Further, torque acting on the spool may be detected by a strain gauge or the like.

  (B) In the above-described embodiment, the relationship between the yarn length and the spool rotational speed is learned by paying attention to the fact that the relationship between the thread length per one spool rotation and the spool rotational speed is a linear function. A yarn length detector may be mounted, or the relationship between the yarn length and the spool rotational speed may be obtained by a quadratic function.

  (C) In the above embodiment, the tension information “3” is set to the optimum value of the tension during normal learning, but the present invention is not limited to this.

  (D) Although the fishing line previously stored in the storage unit 67 is used as the reference fishing line in the embodiment, the present invention is not limited to this. For example, a fishing line in which the relationship between the thread length and the spool rotation speed is determined by normal learning first may be used as the reference fishing line.

  (E) In the above embodiment, the speed or tension step number is set by the adjustment lever, but the speed or tension step number may be set by an operation switch. In this case, the number of steps may be increased or decreased according to the operation time or the number of operations.

  (F) In the above embodiment, the present invention has been described by taking the electric reel in which the motor 12 is disposed in front of the spool 10 as an example, but the present invention is not limited to this.
