Tension display device for double bearing reel

The present invention relates to a tension display device, and more particularly to a tension display device for a dual-bearing reel. The fishing line is a reel attached to a dual-bearing reel, and the tension display device can display the tension acting on the fishing line.

A double-bearing reel is known as a water depth display device having a meter. In the double-bearing reel having a water depth display device, the water depth of the fishing group is displayed by displaying the line length of the fishing line discharged from the reel. The length of the line is related to the number of revolutions of the reel. If the thickness of the fishing line is different, the relationship between the length of the line and the number of rotations will change. Therefore, it is known that the two-bearing reel attached to the water depth display device, that is, the electric reel, has a function of providing a relationship between the line length and the line of the fishing line whose rotation number is unknown (for example, refer to Patent Document 1). At this time, for example, the fisherman grasps the fishing line by the tip of the finger and applies tension to the fishing line, and attaches the fishing line to the reel. When the tension is changed when the fishing line is attached to the reel, the increase ratio of the winding diameter changes, and the relationship between the length of the line and the number of rotations cannot be accurately obtained. Therefore, it is conventionally known that the tension is measured by the negative current of the motor, and the measurement result is displayed (for example, refer to Patent Document 2).

In the conventional configuration, when the relationship between the length of the wire and the number of rotations of the reel is obtained, the tension is detected by the negative current of the motor, that is, the torque. Therefore, if the winding diameter is increased, even if the tension is the same, the torque (negative current) becomes larger corresponding to the winding diameter. Therefore, a value larger than the actual tension is displayed, and the tension cannot be accurately displayed. In particular, in the case of a reel of a deep groove having a large difference between the winding diameter at the start of winding and the winding diameter at the end of winding, since the ratio of the change in the winding diameter is larger than the number of rotations, accuracy cannot be accurately performed. Show tension.

An object of the present invention is to accurately display the tension when the relationship between the length of the wire and the number of rotations of the reel is desired.

The tension display device of the double-bearing reel of Invention 1 is a device that displays the tension acting on the fishing line wound in the reel of the dual-bearing reel. The tension display device includes a display, a torque detecting means, a rotation number detecting means, a memory means, a relationship accommodating means, a reading means, a wire winding diameter calculating means, and a tension calculating means. The torque detecting means detects the torque acting on the spool. The rotation number detecting means detects the number of rotations of the reel. The memory means is a relationship in which the reference line length and the number of rotations of the reference fish line are memorized in advance. The relationship accommodation means is the line length at which the fishing line can be obtained, and the number of rotations of the reel detected by the rotation number detecting means. Department, and accommodated in memory means. In the reading means, when the relationship is obtained by the relationship accommodating means, the reference line length corresponding to the number of rotations detected by the rotation number detecting means is sequentially read from the memory means. The coil diameter calculation means calculates the coil diameter in order from the number of rotations and the reference line length at the time of reading the reading means, the number of rotations at the time of reading, and the reference line length. The tension calculation means calculates the tension by the torque detected by the torque detecting means and the calculated winding diameter. The tension display device displays the tension information corresponding to the tension calculated by the tension calculating means on the display.

In the tension display device, when the fishing line coil having an unknown relationship between the length of the wire and the number of rotations is attached to the reel, the relationship between the length of the wire and the number of rotations can be obtained by the relationship accommodating means. At this time, the reference line length of the reference fishline stored in the memory means by the reading means is read in accordance with the number of rotations detected. The coil diameter calculation means calculates the coil diameter from the number of rotations at the time of reading, the length of the reference line, the number of rotations at the time of reading, and the length of the reference line. For example, by dividing the difference in the reference line length at the time of reading and before reading by the difference in the number of rotations, the line length per one rotation of the reel can be calculated. The line diameter can be calculated by dividing the line length per rotation by the circumference ratio. Further, the tension can be calculated by dividing the detected torque from the calculated coil diameter. This calculated tension is displayed on the display by means of display means. Here, the line diameter corresponding to the number of rotations is calculated using the relationship of the reference line, and the tension corresponding to the torque corresponding to the line diameter is calculated and displayed. Therefore, the tension can be accurately displayed in order to obtain the relationship between the length of the wire and the number of rotations of the reel. When the fisherman sees this display and attaches a certain tension line to the reel, the relationship between the length of the wire and the number of rotations of the reel can be accurately obtained.

The tension display device of the double-bearing reel of Invention 2 is the device of Invention 1, and the double-bearing reel is an electric reel that can drive the reel by a motor. In this case, the electric reel can display the tension with high precision.

The tension display device of the double-bearing reel according to the third aspect of the invention is the device according to the second aspect of the invention, 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 reel is detected by detecting the torque acting on the motor that rotates integrally with the reel, for example, data such as the current value flowing through the motor and the duty ratio of the load are not It is necessary to provide a dedicated torque detecting means such as a magnetostrictive element to detect the torque acting on the spool.

A tension display device for a double-bearing reel according to Invention 4 is the device according to Invention 2 or 3, and the electric reel is provided with a motor in front of the reel. In this case, the reel can be formed into a deep groove as compared with an electric reel in which a motor is disposed in the reel. Even in such a deep groove reel, since the winding diameter can be calculated in order, the tension can be accurately displayed from the start of the winding to the end of the winding.

The tension display device of the double-bearing reel of Invention 5 is the device according to Invention 3 or 4, because the torque detecting means detects the torque by the current value flowing through the motor, and the value of the current flowing to the motor corresponds to Since the load acting on the motor changes, the torque acting on the motor can be further applied to the torque change of the spool. Here, the torque acting on the spool can be easily detected without separately providing a means for detecting the torque.

The tension display device of the double bearing reel of Invention 6 is as inventive 5 Further, the apparatus further includes correction means for correcting the tension calculated by the tension calculation means from the start of the acquisition to the predetermined time when the relationship is obtained by the relationship accommodation means. In the case of the electric reel, a speed reduction mechanism such as a planetary gear mechanism that decelerates the rotation of the motor is usually provided. In this speed reduction mechanism, a lubricant such as lubricating oil is filled. Until the lubricant is warmed up, since the fluidity of the lubricant is low and the resistance of the lubricant is large, the value of the current flowing to the motor from the start of the rotation to the predetermined time becomes large. Therefore, when the torque is detected from the current value, the tension can be corrected and the influence by the lubricant can be corrected, and the tension can be displayed more accurately.

A tension display device for a double-bearing reel according to Invention 7 is the device according to Invention 1 or 2, and the torque detecting means is a magnetostrictive element provided on a rotating shaft of the reel. In this case, since the torque acting on the reel can be detected more accurately, the tension can be displayed more accurately. Moreover, since the torque can be detected irrespective of the presence or absence of the motor, even if the two-bearing reel having the manual winding of the water depth display device and the manual winding of the electric reel obtain the relationship between the length of the reel and the number of rotations, It is also possible to display the tension with high precision.

The tension display device of the double-bearing reel according to any one of the first to seventh aspects of the invention, further comprising: a line type setting means for setting a type of the fishing line, and a tension information changing means. The tension information changing means changes the relationship between the tension and the tension information calculated by the tension calculating means in accordance with the type of the fishing line set by the line type setting means. In this case, for example, a fishing line in which a plurality of polyethylene fibers are combined and braided ( A fishing line of a plurality of lines such as a PE line or a fishing line of a fluorocarbon (fluorocarbon) fishing line (hereinafter referred to as a carbon fluoride line) can display different tensions from the same tension information. In the case of the PE wire, since the plurality of fibers are incorporated, it is wound more tightly than the single-line fishing line, that is, if the large tension is not taken up, the predetermined thickness (number) may not be obtained. A full length of fishing line of a predetermined length is attached to the reel. Even in this case, as described above, by changing the relationship between the tension information and the tension depending on the type of the fishing line, the fisherman can remember only one tension information regardless of the type of the fishing line. Therefore, as long as the single tension information displayed is matched, the fisherman can attach the fishing line to the reel with a certain tension.

According to the present invention, the line diameter corresponding to the number of rotations is calculated using the relationship of the reference line, and the tension corresponding to the torque corresponding to the line diameter is calculated and displayed. Therefore, the tension can be accurately displayed in order to obtain the relationship between the length of the wire and the number of rotations of the reel. When the fisherman sees this display and attaches the fishing line by a certain tension, the relationship between the length of the wire and the number of rotations of the reel can be accurately obtained.

<Composition of the meter housing shell>

The meter housing 4 is placed on the upper portions of the first side plate 7a and the second side plate 7b as shown in Figs. 1 and 2, and is screwed to the outside of the first side plate 7a and the second side plate 7b. side.

Also, in the learning mode and the speed mode or the tension mode, different tensions are displayed even in the same stage. In the speed mode or the tension mode, the value of the phase is approximately close to the tension value acting on the fishing line at that time. Moreover, even if the learning mode is at the same stage, there is a different tension due to the type of the fishing line. Moreover, in this embodiment, the learning mode is exemplified by ordinary learning and volume learning. Ordinary learning is a learning mode for learning the relationship between the number of rotations and the length of one line.

<Configuration of Control System of Reeler>

As shown in Fig. 5, the cord reel control unit 60 is constituted by, for example, a microcomputer including a CPU, a RAM, a ROM, an I/O interface, and the like, and a liquid crystal driving circuit.

The reel control unit 60 is connected to an adjustment operation lever 5, an operation button unit 62, a reel sensor 63, a reel counter 64, a buzzer 65, and a motor drive circuit 66, And a display 61, a memory unit 67, and other input and output units. The operation button portion 62 has three switches as described above. The spool sensor 63 is provided to detect the number of rotations, the direction of rotation, and the rotational speed of the spool 10. The reel sensor (rotation number detecting means) 63 is a magnetic force capable of detecting a magnet (not shown), and has, for example, two magnet detecting elements including a Hall element or a reed switch. The rotation direction of the spool 10 can be detected by detecting the magnet by any of the magnet detecting elements. The magnet rotates in conjunction with the rotation of the spool 10. The reel counter 64 is a pulse that counts from the reel sensor 63. By the output of the reel counter 64, it is possible to detect the number of reels X of the reel and the rotational speed of the reel 10 which are rotated several times from the reel 10 to be wound.

The buzzer 65 is provided for various notifications such as water depth display. The motor drive circuit 66 is for controlling the motor 12 to have a constant speed or by pulse width modulation (PWM) (Pulse Width Modulation). It is set by the tension being driven by a certain amount. The motor drive circuit 66 is a current detecting portion 66a that detects a current flowing through the motor 12. The current detecting unit 66a is an example of a torque sensor. The memory unit 67 is composed of, for example, a rewritable nonvolatile memory such as an EEPROM (Electrically Erasable Programmable Read-Only Memory) or a flash memory. In the memory unit 67, as shown in Fig. 6, a shed (fish migration layer depth) position data memory area 67a, a learning material memory area 67b, a predetermined line data memory area 67c, and a velocity data memory area 67d are provided. And a torque data storage area 67e, a tension information memory area 67f, and other data storage areas 67g.

In the shed (fish migration layer depth) position data memory area 67a, display information such as the position of the shed (fish migration layer depth) set when fishing is performed is stored. In the learning material memory area 67b, learning materials showing the relationship between the actual line length obtained by the learning mode and the number of rotations of the reel 10 are memorized. In the predetermined line data storage area 67c, the relationship between the reference line length of the fishing line of the predetermined thickness and length of the predetermined number and 300 mm of the PE line, such as the PE line, and the number of rotations of the reel 10 is stored in advance. This relationship is used to calculate the tension in the learning mode. In the speed data memory area 67d, the upper limit value of the winding speed (rpm) of the reel 10 of each of the number of stages SC is stored in advance. In the torque data storage area 67e, the upper limit value of the winding torque (amperes) of the motor 12 of each of the number of stages SC is stored in advance.

In the speed data memory area 67d, the speed data SS= 257 rpm, the speed of the second speed when the number of segments SC is 1 speed is stored. When SS=369rpm, SS=503rpm in the case of 3rd speed, SS=665rpm in the case of 4th speed, and SS=1000rpm in the case of 5th speed. In the torque data storage area 67e, for example, when the number of segments SC is one segment, the torque data of the upper limit is TS=2A, the case of two segments is TS=3.5A, and the case of three segments is TS=5A. In the case of 4 segments, TS=6.5A and 5 segments are TS=8A. The relevant torque is corrected to the tension of the corresponding coil diameter.

In the tension information memory area 67f, 9-stage tension information of 1-9 displayed by the tension display field 61c in the learning mode, and 10-stage tension information of 0-9 displayed by the speed mode or the tension mode are stored. . The 9-stage tension information displayed by the speed mode or the tension mode is roughly the tension actually applied to the fishing line. For example, when the tension information is "1", the tension is 0.3 kg to 1.5 kg, and when the tension information is "9", the tension is 8.5 kg or more.

The tension in each stage of the learning mode is as shown in Fig. 12. In the learning mode, the angler is better to take the fishing line from a certain tension. At this time, the PE line which is difficult to extend and the fluorocarbon line which is easy to extend are not wound up by the same tension, and it is necessary to wind up the PE line with a tension which is larger than the easy extension of the fluorocarbon line. Here, as shown in Fig. 12, the same tension information may be different depending on the type of the fishing line. 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 fluorocarbon line (FL) is 0.5 kg to 0.8 kg. Therefore, the angle of the fisherman is not related to the type of the fishing line during normal learning. For example, the line of the fishing line is attached to the reel 10 so as to be the tension information "3".

In other data memory areas 67g, PWM control is accommodated. The load works better than the information and all kinds of temporary information. Moreover, the data of the maximum load ratio and the minimum load ratio of each torque segment number SC are also accommodated.

The reel control unit 60 is configured by a software realized function, and includes a motor control unit 70 that controls the motor 12 and a display control unit 71 that controls the display 61. The display control unit 71 includes a water depth display unit 72 that displays a water depth in the water depth display area 61a, and a tension display unit 73 that displays tension in the tension display area 61c. The tension display unit 73 includes a relationship housing unit 74, a reading unit 75, a coil diameter calculating unit 76, a tension calculating unit 77, a correcting unit 78, a line type setting unit 79, and a tension information changing unit. 80. The relationship housing portion 74 obtains the line length of the fishing line whose relationship between the line length and the number of reel rotations is unknown, and the number of rotations of the reel 10 detected by the reel sensor 63 during normal learning. The relationship is such that the number of rotations of the reel 10 is related and the line length is accommodated in the learning material memory area 67b of the memory unit 67.

When the above-described relationship is obtained by the relationship accommodating portion 74, the reading unit 75 sequentially reads out the number of rotations detected by the reel sensor 63 from the storage unit 67 in order to be accommodated in the predetermined line data storage area. The reference line length of 67c (for example, the line length of the PE line 6 and 300 m). The wire winding diameter calculation unit 76 is the winding diameter of the reel X1 and the reference line length LN1 when reading from the reading unit 75, and the number of reeling rotations X2 and the reference line length LN2 at the time of reading. SD1 is calculated in order. Specifically, by dividing the line length (LX1-LX2) subtracted from the previous line length LN2 from the line length LN1 at the time of reading by the difference (X1-X2) of the number of revolutions of the reel, it is possible to calculate the reel each time. Rotating a line length L. The line diameter SD can be calculated by dividing the line length L by π.

The tension calculation unit 77 calculates the tension T by dividing the coil diameter SD obtained by the torque data TR obtained by the current detecting unit 66a. The correction unit 78 corrects the calculated tension for a predetermined time (for example, 30 seconds) at the time of starting the winding. This is because the viscosity of the lubricating oil filled in the planetary gear mechanism 26, which will be described later, of the reel driving mechanism 13 is high at the start of the winding, and the resistance of the lubricating oil is large. Therefore, the calculated tension T is decreased by the elapsed time t from the start of the winding up to the predetermined time until the influence of the lubricating oil is reduced. For example, in the first 5 seconds, the correction coefficient 0.5 is multiplied for the tension T, and the correction coefficient is increased by 0.1 every 5 seconds thereafter. Thereby, it is possible to suppress the fluctuation of the display of the tension T after the start of the winding. Further, after the winding is started, even if any tension T is calculated, the tension information "3" may be displayed regardless of the tension.

The tension information tension corresponding to the calculated or corrected tension T is displayed on the tension display field 61c of the display 61 of the display unit 73.

The thread type setting unit 79 is a type of user who sets the type of the fishing line attached to the reel 10 at the time of normal learning. In this embodiment, two types of fishing lines of PE wire and fluorocarbon wire can be set. The tension information changing unit 80 changes the relationship between the tension and the tension information calculated by the tension calculating unit 77 in accordance with the type of the 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 in such a manner that the tension line information is displayed as "3" in such a manner that the tension line information is attached to the reel 10. In the tension information changing unit 80, at the time of normal learning, the tension of the tension information is displayed corresponding to the type of the fishing line attached to the roll. T is changed by, for example, the relationship shown in Fig. 12. Therefore, even with the same tension information, the tension of the PE wire is larger than the tension of the fluorocarbon wire.

The tension information corresponding to the calculated or corrected tension T is displayed on the tension display field 61c of the display 61 of the tension display unit 73.

The display 61, the current detecting unit 66a, the reel sensor 63, the memory unit 67, and the tension display unit 73 constitute the tension display device 6 of the double-bearing reel of the present invention.

<Composition of reel>

The spool 10 is rotatably mounted integrally with the spool shaft 14. The spool 10 has a cylindrical winding portion 10a and a first flange portion 10b and a second flange portion 10c which are integrally formed on both sides of the winding portion 10a. The reel 10 is a deep groove type having a diameter that is smaller than the diameter of the first flange portion 10b and the second flange portion 10c (for example, a diameter of half or less). The spool shaft 14 is fixed to the inner peripheral portion of the winding head portion 10a by a suitable fixing means such as press fitting.

The first end of the spool shaft 14 is supported by the spool support portion 17 by the first bearing 18a as described above. The second end (the right end of the third figure) of the spool shaft 14 is the second hub portion 8d supported by the second side cover 8b by the second bearing 18b.

The spool shaft 14 has 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 end side on the second end side of the large diameter portion 14a. Small diameter portion 14c. The clutch mechanism 16 is disposed on the second small diameter portion 14c side of the spool fixing portion of the large diameter portion 14a. The adapter pin 16a is installed in the radial direction.

<Configuration of Clutch Mechanism and Clutch Control Mechanism>

The clutch mechanism 16 includes a clutch pin 16a and a clutch recess 16b which is formed by being recessed in the radial direction on the left end surface of the third figure of the pinion gear 32 which will be described later. The pinion gear 32 constitutes the clutch mechanism 16 and is configured by a first rotation transmission mechanism 24 which will be described later. The pinion gear 32 moves in the direction of the spool shaft 14 between the clutch engagement (ON) position shown in Fig. 3 and the clutch OFF position on the right side of the third diagram of the clutch engagement (ON) position. In the clutch engaged (ON) position, the clutch pin 16a is engaged with the clutch recess 16b so that the rotation of the pinion gear 32 is transmitted to the spool shaft 14, and the clutch mechanism 16 is in the clutch engaged state. In the clutch engaged state, the pinion gear 32 and the spool shaft 14 are integrally rotatable. Also, in the clutch OFF position, the clutch recess 16b is away from the clutch pin 16a so that the rotation of the pinion 32 cannot be transmitted to the spool shaft 14. Therefore, the clutch mechanism 16 is in a clutch OFF state, and the spool 10 is freely rotatable.

The clutch control mechanism 20 is a swing between a clutch engagement (ON) position indicated by a solid line in the second diagram of the clutch operating member 11 and a clutch OFF position displayed by a two-point lock line in FIG. The clutch mechanism 16 is switched to the clutch engaged (ON) state and the clutch open (OFF) state.

<Configuration of reel drive mechanism>

The spool drive mechanism 13 drives the spool 10 in the winding direction. Further, the traction force is prevented from being generated in the reel 10 at the time of winding, and the fishing line is cut. As shown in FIGS. 2 to 4, the reel drive mechanism 13 includes a motor 12 and a reverse prohibition unit 23 that prohibits rotation of the motor 12 in the wire winding direction, and a first rotation transmission mechanism 24 and 2 Rotating the communication mechanism 25. The first rotation transmission mechanism 24 transmits the rotation of the motor 12 to the reel 10 at a reduced speed. The second rotation transmission mechanism 25 transmits the rotation of the operation lever 2 to the reel 10 by the first rotation transmission mechanism 24 at a higher speed.

The motor 12 is housed inside the second connecting member 7d described above. The motor 12 is prohibited from rotating in the line discharge direction by the reverse prohibiting portion 23 in the form of a roller clutch.

The first rotation transmission mechanism 24 is a planetary gear mechanism 26 that is coupled to the output shaft 12a of the motor 12. The planetary gear mechanism 26 transmits the reduction ratio of the motor 12 to the reel 10 at a speed reduction ratio ranging from 1/20 to 1/30. The planetary gear mechanism 26 includes a first planetary reduction mechanism 27 coupled to the output shaft 12a of the motor 12 and a second planetary reduction mechanism 28 coupled to the first planetary reduction mechanism 27. The planetary gear mechanism 26 is housed in a casing 40 that is rotatably supported at both ends in the second side plate 7b and the mechanism mounting plate 19. An internal gear of the first planetary reduction mechanism 27 and the second planetary reduction mechanism 28 is formed on the inner circumferential surface of the casing 40. The sun gear of the first planetary reduction mechanism 27 is coupled to the output shaft 12a so as to be rotatable. The sun gear of the second planetary reduction mechanism 28 is a pinion bracket that is coupled to the first planetary reduction mechanism 27 so as to be rotatable together. Formed in the shell The output of the internal gear of 40 is communicated to the reel 10.

As shown in FIGS. 2 and 3 , the first rotation transmission mechanism 24 further includes a first gear member 81 , a second gear member 82 that meshes with the first gear member 81 , and a second gear member 82 . Engaged pinion 32. The first gear member 81 is formed on the outer circumference 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 a driven gear 55 that is also meshed with the uniform winding mechanism 22. The second gear member 82 is disposed between the outer surface of the mechanism mounting plate 19 and the second side plate 7b. The second gear member 82 is an intermediate gear for integrally transmitting the rotation of the first gear member 81 to the pinion gear 32 in the rotational direction. The second gear member 82 is rotatably supported by the mechanism mounting plate 19. The pinion gear 32 is rotatably disposed around the spool shaft 14 and is movably attached to the second side plate 7b in the axial direction. The pinion gear 32 is controlled to move between the clutch engagement (ON) position and the clutch OFF position in the axial direction by the clutch control mechanism 20.

As shown in FIGS. 2, 3, 4, and 5, the second rotation transmission mechanism 25 includes a handle shaft 30 that integrally rotates the operation lever 2, a drive gear 31, and a second 3 gear member 83 and traction mechanism 29.

The handle shaft 30 is rotatably supported by the first side portion 8c of the second side plate 7b and the second side cover 8b as shown in Fig. 3 . In the handle shaft 30, the traction washer 37 of the traction mechanism 29 is rotatably mounted. In the tip end of the handlebar shaft 30, the operating lever 2 is integrally rotatablely coupled. And in the handle shaft 30, the ratchet roller 35 of the first one-way clutch 34 is It can be installed in a rotatable manner. The ratchet roller 35 is attached in a state in which the movement in the axial direction (the left side in FIG. 4) is restricted. The ratchet roller 35 is prohibited from rotating in the wire discharge direction by a dice (not shown). The base end of the handle shaft 30 is rotatably supported by the second side plate 7b by a bearing (not shown). Further, the handle shaft 30 is supported by the first hub portion 8c of the second side cover 8b by the second one-way clutch 36 of the roller type. The handle shaft 30 is prohibited from rotating in the wire discharge direction by the first one-way clutch 34. The traction mechanism 29 is made to be operable by prohibiting the rotation of the handle 30 in the wire discharge direction. The second one-way clutch 36 quickly prohibits the rotation of the handle shaft 30 in the line discharge direction.

The drive gear 31 is rotatably mounted on the handle shaft 30. The drive gear 31 is pushed by the traction washer 37. The drive gear 31 is braked by the traction mechanism 29 in the rotation of the wire discharge direction. Thereby, the rotation of the spool 10 in the wire discharge direction is braked.

The third gear member 83 is provided to transmit the rotation of the operating lever 2 to the spool 10. The third gear member 83 is a pinion bracket that is coupled to the second planetary reduction mechanism 28 so as to be rotatable together. The third gear member 83 is a pinion bracket that meshes with the drive gear 31 and transmits the rotation of the operation lever 2 to the second planetary reduction mechanism 28. The rotation transmitted to the pinion bracket is transmitted to the pinion gear 32 through 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 substantially "1".

The traction mechanism 29 has a traction washer 37 and a star tractor 3 for adjusting the traction. The traction mechanism 29 is for discharging the wire of the reel Rotary braking in the direction to prevent the fishing line from being cut. The traction mechanism 29 idly rotates the spool 10 in the line discharge direction when a force equal to or higher than the set traction force acts on the spool 10.

<Composition of other institutions>

The throwing control mechanism 21 pushes the both ends of the spool shaft 14 to brake the spool 10 as shown in Fig. 3 . The throwing control mechanism 21 has a brake cap 51 screwed to the outer peripheral surface of the second boss portion 8d, a first brake shoe 52a, and a second brake shoe 52b. The first brake pad 52a is disposed in the spool support portion 17 and is in contact with the first end of the spool shaft 14. The second brake pad 52b is disposed in the brake cap 51 and is in contact with the second end of the spool shaft 14.

The uniform winding mechanism 22 has a screw shaft 53 that is rotatably supported at both ends on the first side plate 7a and the second side plate 7b, and a fishline guide 54 that is engaged with the screw shaft 53. An intersecting spiral groove 53a is formed on the outer circumferential surface of the screw shaft 53. In the right end of the third shaft of the screw shaft 53, a driven gear 55 coupled to the spool drive mechanism 13 is integrally rotatably mounted. The line guide 54 is guided along the axial direction of the screw shaft 53. The fishline guide 54 is a spiral groove 53a that is engaged with the screw shaft 53, and reciprocates along the screw shaft 53 by the rotation of the screw shaft 53. Thereby, the fishing line is wound around the reel 10 substantially uniformly in conjunction with the rotation of the reel 10 in the wire winding direction.

<Control action of the reel control unit>

The control operation of the reel control unit 60 is based on Fig. 7 to Figure 11 shows the flow chart. Further, the flowcharts shown in FIGS. 7 to 11 are examples of the control program, and the control program of the present invention is not limited thereto.

In the present invention, the line length L can be calculated by approximating a straight line by the relationship between the line length Y and the number of reel rotations X per revolution of the reel.

The fishing line having a small thickness and an unknown length is wound up in a layered manner from the winding diameter Bmm to the reel 10, and all the fishing line coils are taken up by the c rotation. Next, when the fishing line of Smm is discharged from this state, the reel 10 is rotated by d.

Now, the relationship between the number of revolutions of the reel X and the length Y of the reel for one revolution of the reel is the number of rotations of the reel X on the horizontal axis and the length of the rotation per revolution of the reel on the vertical axis. Since the straight line is defined, if the inclination is A, it can be expressed by the following formula.

Y=AX+Bπ (1)

The line length Y is calculated by obtaining the inclination A and the slice Bπ of the above formula (1).

Specifically, from the four pieces of data, that is, the discharge length S, the diameter B, the number of reel rotations c, and the number of discharge rotations d, the inclination A of the straight line can be obtained by the following equation.

A=2(S-Bπd)/d(2c-d)

For example, when the reel 10 is wound up from the initial rotation of the winding for 2,000 rotations, and the reel is rotated by 60 turns when the reel is sprinkled for 10 m, the reel diameter (winding diameter) of the reel 10 is 30 mm. The inclination A of the straight line is as follows.

A=2(10000-94.2*60)/60(2*2000-60)(2)=0.0368

Further, if the approximate vertical line of the inclination A and the slice Bπ can be determined, the linear integration process (surface accumulation processing) can be performed once every revolution of the reel, and the initial from the winding to the end of the winding can be obtained. For example, the line length L1~LN of each revolution of the reel. In addition, the water depth LX at the time of the number of reels of the reel at the time of winding is set to "0", and the relationship between the water depth LX (= LN) and the number of reels X of the winding start is calculated from, for example, a map. The form (LX=MAP(X)) is stored in the learning material memory area 67b of the memory unit 67.

When the reel 10 is actually rotated, the line length LN is read from the map of the memory unit 67 based on the number of reels X detected by the reel sensor 63 at that time, according to the read line length LN. The water depth of the fishing group (water depth at the tip of the fishing line) is displayed on the display 61.

Next, the specific control processing by the reel control unit 60 will be described based on the control flowchart subsequent to FIG.

When the electric reel is connected to the external power supply via the power supply line, the initial setting is performed in step S1 of Fig. 6. In this initial setting, the count value of the reel 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 to the slave mode. From the upper mode, the water depth display field 61a shows the pattern of the water depth from the water surface.

Next, display processing is performed in step S2. In the display processing, various display processing such as water depth display is performed. Here, in the speed mode, the number of speed segments that are operated by adjusting the operating lever 5 in the number-of-segment display field 61b is displayed, and the number of tension segments is displayed in the tension mode. And display the speed mode and Any of the control modes of the tension mode.

In step S3, it is judged whether or not any one of the operation button portions 62 or the adjustment operation lever is operated. It is judged in step S4 whether or not the reel 10 is rotated. This judgment is judged by the output of the reel sensor 63. It is judged in step S5 whether or not there are other commands and inputs.

When any of the switches of the operation button portion 62 or the adjustment operation lever 5 is operated, the process proceeds from step S3 to step S6 to execute the switch input process. When the rotation of the reel 10 is detected, the flow proceeds from step S4 to step S7. Each operation mode process is executed in step S7. When there are other commands or inputs, the process proceeds from step S5 to step S8 to perform other processing.

In the switch input processing of step S6, it is judged by step S11 of Fig. 8 whether or not the adjustment operation lever 5 is pressed. In step S12, it is judged whether or not the motor control selection switch SW1 is pressed. In step S13, it is judged whether or not the return-to-zero switch SW2 and the high-break (the line is disconnected before the fishing group is dropped) switch SW3 are simultaneously pressed for 2 seconds or longer. In step S14, it is judged whether or not another switching operation (for example, the zero return switch SW2 and the high-break (the disconnection before the fishing group is dropped) the short-press operation and the long-press operation of the switch SW2) are operated. This long-pressing operation is to obtain the relationship between the line length LN of the fishing line attached to the reel 10 and the number of reels X of the reel, and to perform the learning mode in the memory unit 67 by the map form (LX=MAP(X)). The operation used.

If it is judged that the adjustment operation lever 5 is operated, the flow proceeds from step S11 to step S15. In step S15, the number of segments SC of the adjustment lever 5 is taken in. In step S16, it is determined whether the number of segments SC of the adjustment lever 5 is "0". When the number of stages SC of the adjustment lever 5 is "0", the motor 12 is turned off (OFF). When the number of stages SC of the adjustment operation lever 5 is not "0", the process proceeds from step S16 to step S18. In step S18, it is judged whether or not the motor control mode is the speed constant mode. In the speed-constant mode, the process proceeds to step S19, and the motor 12 is controlled so as to correspond to the speed of the number of stages SC of the adjustment operation lever 5, and the process proceeds to step S12. When it is not the speed constant mode, the process proceeds from step S18 to step S20, and the tension acting on the fishing line is controlled so as to adjust the tension of the number of stages SC of the operation lever 5, and the process proceeds to step S12.

If it is judged that the motor control selection switch SW1 is operated, the flow proceeds from step S12 to step S21. In step S21, it is determined whether or not the speed is set to a constant mode. When the speed is set to a constant mode, the process proceeds to step S22 to set the motor control mode to the constant tension mode. This is because if the motor control selection switch SW1 is pressed in the speed-constant mode, it is necessary that the fisherman wants to switch to the tension-constant mode. Thereby, the tension control is performed corresponding to the operation of the adjustment operation lever 5. When it is not the speed constant mode but the tension constant mode, the process proceeds from step S21 to step S23, and the motor control mode is set to the speed constant mode. If the processing of step S22 and step S23 is completed, the process proceeds to step S13.

When it is judged that the return-to-zero switch SW2 and the high-break (the line is disconnected before the fishing group is dropped) switch SW3 are simultaneously pressed for 2 seconds or more, the process proceeds from step S13 to step S24 in which the learning mode is performed. In step S24, the switching mode of the corresponding fisherman determines that the learning mode is normal learning or scrolling learning. Enter the learning mode, if the fisherman operates the zero switch SW2, set it to step General learning at step S25. At this time, if the fisherman operates the motor control switch SW1 instead of operating the return-to-zero switch SW2 and operates the return-to-zero switch SW2, the scroll-down learning in step S26 is set. If the setting of these is completed, the process proceeds to step S14.

When the other switch input is performed, 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 to the shed (fish migration layer depth) is performed, and the process returns to the seventh. The main example of the stroke shown in the figure.

In the normal learning processing of step S25, it is judged by step S31 of Fig. 9 whether or not the winding start operation is operated. In the normal learning process, the return-to-zero switch SW2 is used when the normal learning starts the case of the fishing line winding or the case where the winding is finished. When the winding is not started, the process proceeds to step S32, and as shown in Fig. 13(a), the type of the fishing line is displayed. The type of the fishing line is displayed in the number-of-segment display area 61b, and "PE (PE line)" or "FL (carbon fluoride line)" indicating the type of the fishing line is displayed. In the water depth display area 61a, "E1 (learning processing of PE line)" or "E2 (learning processing of fluorocarbon line)" for displaying the learning line of the fishing line of any of the types is displayed.

In step S33, it is judged whether or not the motor control selection switch SW1 is operated. In the normal learning process, the motor control selection switch SW1 is used to select the type of the fishing line. When the motor control selection switch SW1 is operated, the flow proceeds from step S33 to step S34. In step S34, when the PE line has been displayed in step S32, that is, the case where the PE line has been set, the process proceeds to step S35. In step S35, the type of fishing line is switched to fluorocarbon line. When the fluorocarbon line is displayed in step S32, the process proceeds from step S34 to step S36, and the type of the fishing line is switched to the PE line. By the switching of these, the tension information of the fishing line in which the tension information of the nine stages in the normal learning time is selected is set. If the processing of these is completed, the process returns to step S31. Further, in step S33, the process returns to step S31 until the motor control selection switch SW1 is operated.

When the selection of the type of the fishing line is completed, the fisherman is operating the zero return switch SW1 to start the winding of the fishing line toward the reel 10. When the winding of the fishing line is started, the process proceeds from step S31 to step S41. In step S41, the elapsed timing for measuring from the start of learning to a predetermined time (for example, 20 seconds to 40 seconds, in this embodiment, 30 seconds) is started. This timing is a correction for the influence of the lubricating oil to be filled in the planetary gear mechanism 26 for the tension display at the start of the learning. When the winding of the fishing line is started, as shown in Figs. 13(b) to 13(d), the tension information corresponding to the detected tension is displayed in the tension display field 61c. Further, the numerical value corresponding to the number of rotations (rotational position) of the reel 10 is displayed in the water depth display area 61a. Here, for example, a numerical value of 1/6 of the actual number of rotations is displayed. Therefore, in Fig. 13(c), since the display is 20, it is actually shown that the reel 10 is rotated 120 times. Further, the general learning information showing the fishing line of that kind is displayed in the number-of-segment display field 61b. In the case of the fisherman who winds the line by the tension information displayed on the tension display field 61c, the fisherman can learn with high precision.

In step S42, the number of reels of the reel X is increased corresponding to the value of the reel counter 64. For example, the reel sensor 63 is a reel that rotates every revolution When 10 pulses are generated, the reel counter 64 is incremented by 10 each time the reel is rotated, and if the reel counter 64 is increased by 10, the number X of reels is increased by one. In step S43, the current value i detected by the current detecting unit 66a is taken in. In step S44, the number of reels of the reel X is taken in. In step S45, the line length in the number of reels X of the reel taken in step S44 of the reference line of the predetermined line data storage area 67c stored in the storage unit 67 is read. In step S46, the number of reels X1 and the reference line length LN1 at the time of reading, and the number of reels X2 and the reference line length LN2 read before are read as shown in the processing in the reading unit 75 described above. Calculate the coil diameter SD. In step S47, the tension T (T = i / D) is calculated from the calculated coil diameter SD and the detected current value i. In step S48, it is judged whether or not the time is over, that is, whether 30 seconds have elapsed after the fishing line is wound up. When the time is not over, the process proceeds 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. The correction tension Tam is, for example, the correction coefficient 0.5 for the tension T multiplication for the first 5 seconds, and the correction coefficient 0.1 for each of the next 5 seconds. Thereby, it is possible to suppress the fluctuation of the tension display subsequent to the start of the winding.

When the time count is over, the process proceeds to step S50 by skipping step S49. In steps S50 and S34, it is judged whether or not the PE line is selected. When the PE line is set, the process proceeds from step S50 to step S51. In the relationship between the tension information and the tension shown in FIG. 12 in step S51, the tension tension information calculated based on the relationship between the tension and the tension information for the PE wire is displayed in the tension as shown in FIG. Display field 61c. When the fluorocarbon line is set, the process proceeds from step S50 to step S52. In the relationship of the tension information and the tension shown in FIG. 12, the tension tension information calculated in accordance with the relationship between the tension and the tension information for the fluorocarbon line is displayed in the tension display field 61c. Here, it is shown that the relationship between the tension information and the tension is set such that the tension information is "3" in any of the fishing lines so that the normal learning becomes the optimum tension. Therefore, the fisherman can take the fishing line in the reel 10 as long as the tension information is always "3" in the ordinary learning regardless of the type of the fishing line. If the processing of step S51 or step S52 is completed, the process proceeds to step S61 of Fig. 10.

In step S61, it is judged whether or not the winding of the predetermined length of the fishing line is finished. In this judgment, the fisherman is judged by performing the operation of the return-to-zero switch SW2 after winding up the fishing line. After the winding of the thread is completed, for example, a 10m fishing line is spit out to learn the relationship between the number of reels of the reel and the length of the reel for each rotation of the reel, but in step S62, it is judged whether or not the discharge is 10m. This judgment is also judged by whether or not the return-to-zero switch SW2 is operated. Moreover, when the fishing line is coated with a different color every 10 m, for example, the above-mentioned discharge operation can be performed, but depending on the fishing line, there is a case where the color is not applied. In this case, the 10m fishing line is knotted at the apex and the 10m fishing line can be taken up. When the discharge of 10 m of the fishing line is not completed, the process returns to step S31 of Fig. 9.

When the winding of the spool is completed and the rotation of the spool 10 is stopped, the flow proceeds from step S61 to step S63. In step S63, the number of reel rotations X at the time of completion of winding is set to the total number of rotations c. In step S64, the discharge of the corresponding fishing line Subtract the number of reels from the roll X. Similarly to the step S43, for example, if the reel counter 64 is reduced by 10 each time, the number of reel rotations X is decreased by one.

When the line discharge is finished, the flow proceeds from step S62 to step S65. In step S65, the number of reel rotations X, which is reduced by the total number of rotations of the reel, is reduced, and the subtraction value is set to the number of discharge rotations d. This discharge rotation number d is the number of rotations of the spool 10 when the fishing line is discharged 10 m. In step S66, the coil diameter Bπ and the discharge length S are read from the storage unit 67. These two pieces of data are written into the learning material memory area 67b of the memory unit 67 in advance.

In step S67, the approximate one straight line is calculated by obtaining the inclination A of the primary straight line by the above equation (2) by the obtained four pieces of data c, d, Bπ, and S. As a result, the relationship between the rotational length Y of the entire length of the fishing line and the number of reel rotations X of the entire length of the fishing line having an unknown wire diameter and length is determined. The length Y of one revolution of the reel is used to obtain the winding diameter SD (Y/π), and the set torque in the tension mode is corrected by the winding diameter SD so that the tension becomes constant.

In step S68, the obtained linear integral processing is performed, and the relationship between the number of reels X and the line length LN from the initial winding to the end of winding is calculated. And, after the winding is completed, the water depth is set to 0 and the line length LN is converted into the water depth LX. The relationship between the number of revolutions of the reel X and the depth LX is determined.

In step S50, the relationship between the obtained number of reel rotations X and the water depth LX is stored in the memory unit 67 in the form of a map and returned to the main routine. Thereby, the above-described learning process is carried out, and it is not necessary to perform learning across the entire fishing line, and the relationship between the number of reel rotations and the line length which can be changed by the winding diameter can be corrected by performing only the final part of learning. If these treatments are over, Go back to the switch input example stroke.

In the scroll-down learning process of step S26 of Fig. 9, although the detailed description is omitted, the same operation as the normal learning process is performed twice by the lower winding line and the winding line to which the winding is attached. At this time, in the lower winding line, the tension phase is displayed based on the fluorocarbon line, and in the upper winding line, the tension stage is displayed based on the type of the above winding line. For example, when the PE line is wound up, it is changed to a tension phase 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 fisherman enters the learning mode and selects the next-volume learning, as shown in Fig. 14 (a), the "--" which is displayed in the number-of-segment display unit 61b for the scroll-down learning is displayed. Further, in the water depth display area 61a, the information "E3" indicating the scroll learning is displayed. When the zero return button SW2 is operated in this state, the fisherman starts the winding of the lower winding line. In this case, as shown in FIGS. 14(b) to 14(d), the tension information corresponding to the detected tension is displayed in the tension display field 61c. At this time, the tension information is displayed by the stage in which the fluorocarbon line is used as a reference. Further, "E3" for displaying the next volume learning is displayed in the segment number display field 61b. If the fisherman starts the take-up, the tension phase is displayed in the tension display field 81c. Further, the value corresponding to the number of rotations of the reel is displayed in the water depth display area 61a. Here, as in the normal learning, the value of 1/6 of the actual number of revolutions of the reel 10 is displayed. When the winding of the lower winding is completed, the fisherman operates the return-to-zero switch SW2 again in order to tie the winding line to the lower winding line and start winding the fishing line for 10 m. In this case, as shown in Fig. 14(e), the display of the tension display field 61c disappears (extinguished) and the water depth displays the value of the field 61a. Become "0". When the display of the tension display field 61c disappears (extinguished), the driving of the motor 12 generated by the adjustment operation lever 5 is invalid. This point is not shown in the normal learning mode, but this point is the same. The screen when the angler winds up the winding line by 10 m is shown in Fig. 14 (f). Here, the display of the number of fields display field 61c is still disappeared (extinguished). When the winding operation of the 10m winding line is completed, the fisherman re-operates the zeroing switch SW2. In this case, as shown in Figs. 14(g) and 14(h), the character "U" indicating the winding operation of the winding line is displayed in the number-of-segment display field 61b, not the fluorocarbon line, but The stage tension information based on the PE line is displayed in the tension display field 61c. Moreover, since the tension information is displayed in this winding operation, the motor 12 can be used. When the winding of the upper winding is completed, the fisherman operates the return-to-zero switch SW3 again. This is the end of the next volume.

Here, by changing the tension of the lower winding wire and the winding wire, it is possible to take up the lower winding wire which is easy to stretch the nylon (nylon) wire by the weak tension. Therefore, it is possible to make the problem that occurs when the same tension is taken up with the PE wire. In other words, when the lower winding wire which is easy to extend and the winding wire which is difficult to extend the PE wire are taken up by the same tension, if the length of the lower winding wire is determined in advance, the problem that the lower winding diameter becomes small may occur. Further, when the lower winding diameter is set in advance, there is a problem that the line length of the lower winding line becomes long. Further, if the lower winding wire is taken up by the strong tension of the PE wire, the reel may be deformed.

In each operation mode process of step S7 of Fig. 7, it is determined in step S71 of Fig. 11 whether or not the rotation direction of the spool 10 is the line discharge direction. This determination is made by whether or not the magnet detecting element of any one of the reel sensors 63 first emits a pulse. When the rotation direction of the spool 10 is determined to be the line discharge direction, the flow proceeds from step S71 to step S72. In step S72, the data stored in the memory unit 67 is read from the number of reels X of the reel, and the water depth LX is calculated every time the number of rotations of the reel X is decreased. This water depth LX is displayed by the display processing of step S2. In step S73, it is judged whether or not the obtained water depth LX coincides with the bottom position or the position of the shed (fish migration layer depth), that is, whether the fishing group reaches the bottom or the shed (fish migration layer depth). The bottom position or the position of the shed (fish migration layer depth) is set in the memory unit 67 by the long return of the zero return switch SW when the fishing group reaches the bottom or the shed (fish migration layer depth). In step S74, it is determined whether or not it is another mode. When there is no other mode, the operation mode processing is ended and the process returns to the main routine.

When the water depth coincides with the bottom position, the flow proceeds from step S103 to step S105, and the buzzer 65 for reporting the fishing group to the bottom or the shed (fish migration layer depth) is called. In the case of the other mode, the process proceeds from step S74 to step S76, and the other mode designated is executed.

If it is judged that the rotation of the reel 10 is the wire winding direction, the flow proceeds from step S71 to step S777. In step S77, the data stored in the memory unit 67 is read from the number of reels X and the water depth LX is calculated. This water depth LX is displayed by the display processing of step S2. In step S78, it is judged whether or not the water depth coincides with the rim stop position. Return to the main routine if it is not taken to the rim stop position. When the ship edge stop position is reached, the process proceeds from step S78 to step S79. In step S79, in order to report that the fishing group is located at the rim Let the buzzer 65 sound. In step S80, the motor 12 is turned off (OFF). Therefore, the fish can be placed in a position where it is easy to take in when the fish is caught. This rim stop position is set, for example, when the reel 10 is stopped for a predetermined time or longer within a water depth of 6 m.

In the present embodiment having such a configuration, the relationship between the number of rotations of the reel and the length of the wire is calculated by using the relationship of the known reference fishing line, and the winding diameter SD corresponding to the number of rotations of the reel X is calculated, and the winding diameter corresponding to the torque is calculated. Change the tension and display it. Therefore, the tension can be accurately displayed when the relationship between the line length LN and the number of reels X is desired. When the fisherman sees this display and attaches the fishing line by a certain tension, the relationship between the length of the wire and the number of rotations of the reel can be accurately obtained.

<Features>

The above embodiment can be expressed as follows.

(A) The tension display device 6 is a device that displays the tension of the fishing line acting on the reel 10 wound around the double-bearing reel. The tension display device 6 includes a display 61, a current detecting unit 66a as a torque detecting means, a reel sensor 63, a memory unit 67, and a tension display unit 73. The tension display unit 73 includes a relationship housing portion 74, a reading unit 75, a coil diameter calculating unit 76, and a tension calculating unit 77. The current detecting portion 66a detects the torque acting on the spool 10. The reel sensor 63 is the number of rotations of the detected reel 10. The memory unit 67 is a relationship in which the reference line length and the number of rotations of the reference fish line are stored in advance. The relationship housing portion 74 is a line length LN at which the fishing line can be obtained, and a reel detected by the reel sensor 63. The relationship of the number X is rotated and accommodated in the memory unit 67. When the relationship is obtained by the relationship accommodating portion 74, the reading unit 75 sequentially reads the reference line length corresponding to the number of reels X of the reel detected by the reel sensor 63 from the storage unit 67. The coil diameter calculation unit 76 is the spool rotation number X1 and the reference line length LN1 when reading from the reading unit 75, and the number of reel rotations X2 and the reference line length LN2 at the time of reading, and the winding diameter SD Calculated in order. The tension calculation unit 77 calculates the tension T by the torque detected by the current detecting unit 66a and the calculated coil diameter SD. The tension display device 6 displays the tension information of the tension calculated by the corresponding tension calculation unit 77 on the display 61.

In the tension display device 6, when the fishing line which is not known for the relationship between the line length LN and the number of reels X is attached to the reel 10, the line length LN and the number of reels X can be obtained by the relationship accommodating portion 74. relationship. At this time, the reading unit 75 causes the reference line length of the reference fishline stored in the storage unit 67 to be read in accordance with the number of detected reel rotations. The coil diameter calculation unit 76 calculates the coil diameter SD from the number of reel rotations X1 and the reference line length LN1 at the time of reading, and the number of reel rotations X2 and the reference line length LN2 at the time of reading. For example, the difference (LN1-LN2) of the reference line length at the time of reading and before reading is divided by the difference (X1-X2) of the number of revolutions of the reel ((LN1-LN2)/(X1-X2)) , you can calculate the line length of each revolution of the reel. By dividing the line length per rotation by the circumference ratio, the line diameter SD can be calculated. Further, the tension T can be calculated by dividing the detected torque from the calculated coil diameter. The tension information corresponding to the calculated tension is displayed on the display by the display means. Here, the relationship between the number of rotations of the reel and the length of the reel is the number of rotations of the corresponding reel using the relationship of the known reference fishing line. The wire diameter is calculated, and the tension corresponding to the torque corresponding to the wire diameter is calculated and displayed. Therefore, the tension can be accurately displayed in order to obtain the relationship between the length of the wire and the number of rotations of the reel. When the fisherman sees this display and attaches a certain tension line to the reel, the relationship between the length of the wire and the number of rotations of the reel can be accurately obtained.

(B) In the tension display device 6 of the dual-bearing reel, the double-bearing reel is an electric reel that can drive the reel by the motor 12. In this case, the electric reel can display the tension with high precision.

(C) In the tension display device 6, the current detecting portion 66a 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 reel 110 is detected by the torque detection of the motor 12 that rotates integrally with the reel 10, the current value and the duty ratio are flowed by, for example, the motor 12. For the data, the torque acting on the reel can be detected without providing a dedicated torque detecting means such as a magnetostrictive element.

(D) In the tension display device 6, the electric reel is provided with a motor 12 mounted in front of the reel. In this case, the reel 10 can be formed in a deep groove as compared with an electric reel in which a motor is disposed in a reel. Since the reel 10 of the deep groove is also calculated in order of the winding diameter, the tension can be accurately displayed from the start of the winding to the end of the winding.

(E) In the tension display device 6, the torque is detected by the current value flowing through the motor 12. Since the value of the current flowing through the motor 12 changes in accordance with the load acting on the motor 12, the torque acting on the motor 12 further corresponds to the torque change acting on the spool 10. Here, no additional The torque acting on the spool 10 can be easily detected by providing a means for detecting the torque.

(F) In the tension display device 6, when the relationship is obtained by the relationship accommodating portion 74, the tension display unit 73 further reduces the tension calculated by the tension calculating unit 77 from the start of the relationship to the predetermined time. Modified correction unit 78. In the case of the electric reel, a speed reduction mechanism such as a planetary gear mechanism that decelerates the rotation of the motor 12 is usually provided. In this speed reduction mechanism, a lubricant such as lubricating oil is filled. Until the lubricant is warmed up, since the fluidity of the lubricant is low and the resistance of the lubricant is large, the value of the current flowing to the motor 12 from the start of the rotation to the predetermined time becomes large. Therefore, when the torque is detected from the current value, the tension can be corrected and the influence by the lubricant can be corrected, and the tension can be displayed more accurately.

(G) In the tension display device 6, the torque detecting means is a magnetostrictive element provided on a rotating shaft of the spool. In this case, since the torque acting on the reel can be detected more accurately, the tension can be displayed more accurately. Moreover, since the torque can be detected irrespective of the presence or absence of the motor, even if the two-bearing reel having the manual winding of the water depth display device and the manual winding of the electric reel obtain the relationship between the length of the reel and the number of rotations, It is also possible to display the tension with high precision.

(H) The tension display device 6 further includes a wire type setting unit 79 for setting the type of the fishing line, and a tension information changing unit 80. The tension information changing unit 80 changes the tension and tension information calculated by the tension calculating unit 77 in accordance with the type of the fishing line set by the line type setting unit 79. relationship. In this case, for example, a fishing line of a plurality of lines such as a PE wire in which a plurality of polyethylene fibers are combined, and a single-line fishing line such as a fluorocarbon-made fluorocarbon line can display different tensions by the same tension information. In the case of the PE wire, since the plurality of fibers are incorporated, it is wound more tightly than the single-line fishing line, that is, if the large tension is not taken up, the predetermined thickness (number) may not be obtained. A full length of fishing line of a predetermined length is attached to the reel. Even in this case, as described above, by changing the relationship between the tension information and the tension depending on the type of the fishing line, the fisherman can remember only one tension information regardless of the type of the fishing line. Therefore, as long as the single tension information displayed is matched, the fisherman can attach the fishing line to the reel with a certain tension.

For example, a two-bearing reel that does not have a motor for manual winding can also be applied to the present invention. In this case, since the torque cannot be detected by the current value flowing through the motor, it is necessary to provide a dedicated torque sensor. The torque sensor may be a magnetostrictive element mounted on a spool shaft and a coil for reading the output of the magnetostrictive element. The coil is attached to, for example, a reel body. Moreover, the torque acting on the reel can also be detected by a deformation measuring device or the like. To.
