For example, the temperature compensator 40 is configured such that the rate of change is 5% or less in a predetermined temperature range. For example, the temperature compensator 40 is configured such that the rate of change in a predetermined temperature range is 1% or less. The predetermined temperature range is, for example, a temperature range of -10°C to 50°C. A temperature range of -10°C to 50°C is the temperature range of the environment in which the manpowered vehicle 10 is used.

As shown in FIGS. 5 to 7, the location where the temperature compensator 40 is provided can be changed arbitrarily. As shown in FIG. 5, for example, the temperature compensator 40 is provided on the substrate 56 . The temperature compensator 40 is mounted on the substrate 56 . As shown in FIG. 6, for example, the temperature compensator 40 is provided on a flexible printed circuit board 58 . For example, the temperature compensator 40 is provided on the first flexible printed wiring board 58A. As shown in FIG. 7, for example, the temperature compensator 40 is provided in a Wheatstone bridge circuit. For example, the temperature compensator 40 is provided on the base material 46A.

The voltage value output according to the strain detected by the strain gauge 46 changes according to the ambient temperature. For example, when the ambient temperature is -10.degree. For example, when the ambient temperature is 50.degree. When calculating the information about the force applied to the main body 32 in response to the input signal corresponding to the strain, the arithmetic processing unit 48C considers the influence of the temperature around the strain gauge 46 when attempting to reduce the influence of the surrounding temperature. operation must be performed. For example, if a temperature sensor or the like for detecting the temperature around the strain gauge 46 is provided, the number of parts increases.

The temperature compensator 40 of the present embodiment corrects the power input to the Wheatstone bridge circuit 34 to reduce the amount of change in the output of the strain gauge 46 according to the temperature of the operating environment. For example, the temperature compensation unit 40 corrects the voltage value so that when the ambient temperature is -10°C, the voltage value is greater than when the ambient temperature is 20°C. For example, the temperature compensation unit 40 corrects the voltage value so that when the ambient temperature is 50°C, the voltage value is smaller than when the ambient temperature is 20°C. Although the output of the strain sensor changes according to the temperature of the environment in which it is used, the output of the strain sensor is corrected by the temperature compensator 40, so that the force applied to the main body 32 can be accurately adjusted without providing a temperature sensor or the like. well detected.

<Second embodiment>
The component 30 of the second embodiment will be described with reference to FIGS. 9-12. The component 30 of the second embodiment is similar to the component 30 of the first embodiment except that the main body is a fishing rod. In the second embodiment, the same reference numerals as those in the first embodiment are assigned to the same configurations as in the first embodiment, and overlapping descriptions are omitted.

As shown in FIG. 9, in the second embodiment, component 30 includes, for example, fishing tackle 70 . The component 30 of the second embodiment is a component 30 that can be used for fishing. The fishing tackle 70 includes a main body 72, a Wheatstone bridge circuit 34X, an input section 36X, an output section 38X, and a temperature compensation section 40. In this embodiment, for example, body 72 includes a fishing rod 74 . The fishing rod 74 includes a reel 76 and a plurality of fishing rod bodies 78 and.

For example, fishing rod 74 includes multiple fishing rod bodies 78 that are coupled together. Each of the plurality of fishing rod bodies 78 has a tapered shape. The multiple fishing rod bodies 78 include a base rod 78A, a middle rod 78B, and a tip rod 78C. The base rod 78A is a large-diameter portion positioned closest to the base of the rod. The middle rod 78B is a portion located on the tip side of the base rod 78A. The tip rod 78C is a portion located on the tip side of the middle rod 78B. Each fishing rod main body 78 is connected by a well-known connecting method such as a draw-out type and a side-by-side connection type.

For example, a reel seat 78D for attaching the reel 76 is provided on the outer peripheral portion of the base rod 78A. For example, the fishing rod body 78 is provided with a plurality of fishing line guides 78E spaced apart in the axial direction of the fishing rod 74 . For example, the end of the fishing rod body 78 is provided with a top guide 78F. The top guide 78F is attached to the tip side end of the tip rod 78C. A fishing line L pulled out from the reel 76 is guided by a fishing line guide 78E and passed through a top guide 78F. Preferably, the fishing rod main body 78 is formed by baking a prepreg material in which reinforcing fibers such as carbon fibers and glass fibers are impregnated with a thermosetting synthetic resin such as epoxy resin. Preferably, the tip rod 78C is made of a solid material.

For example, the reel 76 is a low profile double bearing reel for baitcasting. For example, the reel 76 includes a handle 80 of the reel 76, a handle shaft 80C of the handle 80, a spool 82, a braking unit 84 that brakes the rotation of the spool 82, and a case 86 of the reel 76. A handle 80 for rotating the spool is arranged in the case 86 . A star drag 88A for drag adjustment is arranged on the case 86 side of the handle 80 .

For example, the handle 80 has an arm portion 80A and a handle 80B rotatably attached to each of both ends of the arm portion 80A. The handle 80 is a double-handle type handle. The arm portion 80A is attached to one end of the handle shaft 80C so as to rotate together with the handle shaft 80C. The arm portion 80A is attached to the handle shaft 80C with a nut 80D.

For example, case 86 includes a light metal such as magnesium alloy. For example, the case 86 has a frame 86A and a first side cover 86B and a second side cover 86C attached to both sides of the frame 86A. Inside the case 86, a thread winding spool 82 is rotatably provided on the case 86 via a spool shaft 82D.

For example, the frame 86A is provided with the spool 82, the clutch lever 86D, and the level wind mechanism 86E. The clutch lever 86D is a lever that the thumb is put on when performing thumbing. The level wind mechanism 86E is a mechanism for winding the fishing line L uniformly within the spool 82. As shown in FIG.

For example, a gear mechanism 90, a clutch mechanism 92, a clutch control mechanism 92A, a drag mechanism 88, and a casting control mechanism 94 are arranged between the frame 86A and the second side cover 86C. Gear mechanism 90 transmits rotational force from handle 80 to spool 82 and clutch lever 86D. The clutch mechanism 92 switches connection and disconnection between the spool 82 and the handle 80 . The clutch control mechanism 92A controls the clutch mechanism 92 according to the operation of the clutch lever 86D. A drag mechanism 88 brakes the spool 82 . A casting control mechanism 94 adjusts the resistance to rotation of the spool 82 . A brake unit 84 for the electrically controlled spool 82 is arranged between the frame 86A and the first side cover 86B. The braking unit 84 is a unit for suppressing backlash during casting.

For example, the frame 86A has a first side plate 86F, a second side plate 86G, and a plurality of connecting portions 86H. The first side plate 86F and the second side plate 86G are portions arranged to face each other with a predetermined gap. The plurality of connecting portions 86H are portions that integrally connect the first side plate 86F and the second side plate 86G. A circular opening 86J is formed in the first side plate 86F. A spool support portion 86K that constitutes the case 86 is detachably fixed to the opening portion 86J. A bearing housing portion 86M in which a first bearing 82M that supports one end of the spool 82 is housed is provided in the spool support portion 86K. The spool support portion 86K has a male threaded portion that is screwed into a female threaded portion formed in the opening 86J. The spool support portion 86K is screwed and fixed to the opening 86J.

For example, the spool 82 has flange portions 82A at both ends in the axial direction. For example, the spool 82 has a tubular bobbin trunk portion 82B located between the two flange portions 82A. The outer peripheral surface of the flange portion 82A on the side of the first side cover 86B is arranged with a slight gap on the inner peripheral side of the opening portion 86J in order to prevent thread jamming. The spool 82 is non-rotatably attached to a spool shaft 82D passing through the inner peripheral side of the bobbin trunk 82B, for example, by serration coupling.

For example, the spool shaft 82D contains non-magnetic metal such as SUS304. The spool shaft 82D penetrates the second side plate 86G and extends outward from the second side cover 86C. One end portion of the spool shaft 82D extending outward is rotatably supported by a boss portion 86L attached to the second side cover 86C by a second bearing 82N. The other end of the spool shaft 82D is rotatably supported with respect to the case 86 via a first bearing 82M. A large diameter portion 82E is formed at the center of the spool shaft 82D. A first small diameter portion 82F and a second small diameter portion 82G supported by the case 86 via a first bearing 82M and a second bearing 82N are formed at both ends of the large diameter portion 82E. The first bearing 82M and the second bearing 82N are rolling bearings whose surfaces are modified to improve corrosion resistance, for example, by forming rolling members, inner rings, and outer rings from SUS404C.

For example, between the first small diameter portion 82F and the large diameter portion 82E on the side of the first side cover 86B, a magnet mounting portion 82H having an intermediate outer diameter is formed. A magnet holding portion 82J is non-rotatably attached to the magnet mounting portion 82H by, for example, serration coupling. The magnet holding portion 82J is formed, for example, by applying electroless nickel plating to the surface of an iron material such as a SUM processed by extrusion or cutting. The magnet holding portion 82J is a quadrangular prism-shaped member having a square cross section and having a through hole 82K formed in the center through which the magnet mounting portion 82H penetrates. The method of attaching the magnet holding portion 82J to the magnet mounting portion 82H is not limited to serration coupling, and various coupling methods such as key coupling or spline coupling can be used.

The end of the large-diameter portion 82E of the spool shaft 82D on the side of the second side cover 86C is arranged in the penetrating portion of the second side plate 86G. An engagement pin 82L that constitutes the clutch mechanism 92 is fixed to the end of the large diameter portion 82E of the spool shaft 82D on the second side cover 86C side. The engaging pin 82L penetrates the large diameter portion 82E along the radial direction, and both end portions of the engaging pin 82L protrude through the large diameter portion 82E in the radial direction.

The clutch lever 86D is arranged behind the spool 82 at the rear between the first side plate 86F and the second side plate 86G. The clutch lever 86D is connected to the clutch control mechanism 92A and slides between the first side plate 86F and the second side plate 86G to switch the clutch mechanism 92 between the connected state and the disconnected state.

For example, the gear mechanism 90 has a handle shaft 80C, a drive gear 90A fixed to the handle shaft 80C, and a cylindrical pinion gear 90B that meshes with the drive gear 90A. The handle shaft 80C is rotatably attached to the second side plate 86G and the second side cover 86C. The handle shaft 80C is prohibited from rotating in the line feeding direction by a roller-type one-way clutch 90G and a pawl-type one-way clutch 90H. A one-way clutch 90G is provided between the second side cover 86C and the handle shaft 80C. The drive gear 90A is rotatably attached to the handle shaft 80C and is connected to the handle shaft 80C via the drag mechanism 88. As shown in FIG.

The pinion gear 90B is a cylindrical member that extends inward from the outside of the second side plate 86G and has the spool shaft 82D passing through its center, and is attached to the spool shaft 82D so as to be axially movable relative to the spool shaft 82D. . The end of the pinion gear 90B on the side of the first side cover 86B is supported by the second side plate 86G by a bearing 90C so as to be rotatable and axially movable with respect to the second side plate 86G. For example, an engagement groove 90D that engages with the engagement pin 82L is formed at the end of the pinion gear 90B on the side of the first side cover 86B. A clutch mechanism 92 is configured by the meshing groove 90D and the engaging pin 82L. For example, the pinion gear 90B has a constricted portion 90E at its intermediate portion, and a gear portion 90F which meshes with the driving gear 90A at the end opposite to the side where the meshing groove 90D is formed.

For example, the clutch control mechanism 92A has a clutch yoke 92B that moves along the direction of the spool shaft 82D. For example, the clutch control mechanism 92A has a clutch return mechanism that turns on the clutch mechanism 92 in conjunction with the rotation of the spool 82 in the line winding direction.

For example, the casting control mechanism 94 has a plurality of friction plates 94A arranged to sandwich both ends of the spool shaft 82D, and a brake cap 94B for adjusting the clamping force of the spool shaft 82D by the friction plates 94A. The friction plate 94A on the side of the first side cover 86B is mounted inside the spool support portion 86K.

For example, the fishing tackle 70 further includes a rotational state detector 52X that detects the rotational state of at least a portion of the main body 72. As shown in FIG. For example, the spool braking mechanism 84E has a braking unit 84, a rotation state detector 52X, a spool control unit 84F, and a mode knob 84G. A braking unit 84 is provided on the spool 82 and the case 86 . The rotation state detector 52X detects the rotation speed of the spool 82. FIG. A spool control unit 84F controls the braking unit 84 . A mode knob 84G is provided for selecting any one of four braking modes for controlling the braking unit 84. FIG.

The braking unit 84 is electrically controllable that brakes the spool 82 by power generation. For example, the braking unit 84 includes a rotor 84A, multiple coils 84B, and a switch element 84C. Rotor 84A includes a plurality of magnets arranged side by side in the rotational direction on spool shaft 82D. A plurality of coils 84B are arranged facing the outer peripheral side of the rotor 84A and connected in series. Both ends of a plurality of coils 84B connected in series are connected to the switch element 84C. The plurality of magnets is four, for example. The number of coils 84B is, for example, four. A braking unit 84 brakes the spool 82 by changing the duty ratio. The braking unit 84 changes the duty ratio by turning on and off the current generated by the relative rotation between the magnet and the coil 84B with the switch element 84C. The braking force generated by the braking unit 84 increases as the ON time of the switch element 84C increases. The longer the ON time of the switch element 84C, the larger the duty ratio.

The four magnets of the rotor 84A are arranged side by side in the circumferential direction and alternately have different polarities. The magnet is a member having approximately the same length as the magnet holding portion 82J. The magnet holding portion 82J has an outer surface with an arcuate cross section and an inner surface with a flat surface. The inner surface of the magnet holding portion 82J is arranged in contact with the outer peripheral surface of the magnet holding portion 82J of the spool shaft 82D.

A sleeve 84D is attached to a position facing the magnet on the inner peripheral surface of the bobbin trunk 82B. The sleeve 84D includes, for example, a magnetic material obtained by applying electroless nickel plating to the surface of an iron material such as SUM processed by extrusion, cutting, or the like. The sleeve 84D is fixed to the inner peripheral surface of the bobbin trunk 82B by an appropriate fixing method such as press-fitting or adhesion. When the sleeve 84D containing a magnetic material is arranged to face the magnet, the magnetic flux from the magnet concentrates and passes through the coil 84B, thereby improving power generation and braking efficiency.

For example, the coil 84B is of a coreless type to prevent cogging and allow the spool 82 to rotate smoothly. For example, coil 84B is not provided with a yoke. The coil 84B is wound in a substantially rectangular shape so that the wound core wire faces the magnet and is arranged within the magnetic field of the magnet. The four coils 84B are connected in series, and both ends of each coil 84B are connected to the switch element 84C. The coil 84B is curved along the rotational direction of the spool 82 in an arc substantially concentric with the rotation axis of the spool shaft 82D so that the distance from the outer surface of the magnet is substantially constant. Therefore, a constant gap can be maintained between the coil 84B and the rotating magnet. For example, coil 84B is attached to circuit board 82O.

For example, the switch element 84C has two parallel-connected FETs (field effect transistors) that can be turned on and off at high speed. A coil 84B is connected in series with each drain terminal of the FET. For example, switch element 84C is mounted on circuit board 82O.

The rotational state detection unit 52X uses, for example, a light projecting/receiving type photoelectric switch having a light projecting portion and a light receiving portion. A detecting tube portion 82C having a plurality of slits spaced apart in the rotational direction is integrally formed on the outer surface of the flange portion 82A of the spool 82 facing the circuit board 82O. The rotation state detection portion 52X has a light projecting portion and a light receiving portion facing each other with the detection tube portion 82C interposed therebetween, and detects the rotation speed of the spool 82 by light passing through the slit.

For example, mode knob 84G is provided to select one of four braking modes. For example, the four braking modes are braking modes in which the first braking force and the second braking force are different, and include four modes of L mode, M mode, A mode, and W mode. L-mode is long throw mode, M-mode is medium-range mode, A-mode is all-round mode, and W-mode is window mode.

The L mode is a mode that uses a fishing line L with a light specific gravity. L mode is a long distance mode for throwing heavy lures with low air resistance such as spoons, metal jigs, or vibrations in favorable tailwind conditions. The L mode is a mode that utilizes the energy immediately after casting to the maximum. The L mode is a braking mode designed to increase the maximum number of revolutions as much as possible and to extend the flight distance by keeping the ball almost free from the middle stage onwards, and the first braking force is set to be the lowest.

The M mode is a braking mode that is set so that you can comfortably cast long distances with a device (plug) with low air resistance, such as a center-of-gravity moving plug, pencil bait, or vibration. The M mode is set to suppress overruns immediately after casting, and to effectively correct the mid-game and beyond to extend flight distance without backlash at the last minute. When using a polyamide resin-based fishing line L with a small specific gravity, it is preferable to set the M mode as a reference.

A mode is a mode that emphasizes extension in the second half while maximizing the energy immediately after casting. The A mode can be used as almighty in most situations regardless of the type of fishing line L, tackle, and wind direction. In particular, when using a fluorocarbon fishing line L with a high specific gravity, it is preferable to set the A mode as a reference.

The W mode is a mode that extends the flight distance by suppressing the backlash as much as possible even in a situation where the flight distance of the tackle is reduced in a strong headwind, and the second braking force is set to be the largest. The W mode is set optimally when throwing a fixed-center-of-gravity minnow or flat-side crank into the headwind, which tend to rotate and decelerate during flight. W mode is set to prevent backlash firmly from low revs even in light casting such as pitching or skipping.

The mode knob 84G is provided on the first side cover 86B so as to be rotatable and positionable in four rotational phases according to the braking mode. A magnet is provided in the mode knob 84G. Circuit board 82P is provided with a mode knob position sensor including two Hall elements spaced apart in the region where the magnet rotates. The mode knob position sensor detects the rotational phase of the mode knob 84G by the on/off change of the two Hall elements due to the passage of the magnet, specifically both on, one on the other off, one off the other on, both off. . The controller sets one of the four braking modes according to the rotational phase of the mode knob 84G.

For example, the spool control unit 84F has a circuit board 82P mounted on the surface of the spool support 86K facing the flange portion 82A of the spool 82, and a control section mounted on the circuit board 82P.

The circuit board 82P is a washer-shaped ring-shaped board with a circular opening at the center, and is arranged substantially concentrically with the spool shaft 82D on the outer peripheral side of the bearing housing portion 86M. The circuit board 82P is attached to the spool support portion 86K so as to be rotatable with respect to the spool support portion 86K. Since the circuit board 82P is positioned so as to be arranged in a predetermined phase with respect to the opening 86J, the circuit board 82P is arranged in a fixed phase even if the spool support portion 86K is turned and removed from the opening 86J. be done.

Since the circuit board 82P is provided on the surface of the spool support portion 86K facing the flange portion 82A of the spool 82, the coil 84B arranged around the rotor 84A can be directly attached to the circuit board 82P. Since the coil 84B can be directly attached to the circuit board 82P, a lead wire connecting the coil 84B and the circuit board 82P becomes unnecessary, and insulation failure between the coil 84B and the circuit board 82P can be reduced. Since the coil 84B is attached to the circuit board 82P attached to the spool support 86K, the coil 84B is also attached to the spool support 86K simply by attaching the circuit board 82P to the spool support 86K. Since the coil 84B is attached to the spool support portion 86K simply by attaching the circuit board 82P to the spool support portion 86K, the spool braking mechanism 84E can be easily assembled. Since the circuit board 82P is rotatably mounted on the spool supporting portion 86K and positioned at a predetermined phase with respect to the opening 86J, the phase between the circuit board 82P and the case 86 does not change. Since the phase between the circuit board 82P and the case 86 does not change, even if a magnet is provided in the mode knob 84G attached to the first side cover 86B that opens and closes and a Hall element is provided in the circuit board 82P, the Hall element will always generate the magnet. It can be detected with the same positional relationship.

A control part contains CPU or MPU, for example. The controllers may be provided at multiple locations separated from each other. The controller may include one or more microcomputers. Preferably, the controller further includes a memory. The storage unit stores various control programs and information used for various control processes. A processing result of the control unit may be stored in the storage unit. The storage unit includes, for example, non-volatile memory and volatile memory. Non-volatile memory includes, for example, at least one of ROM, EPROM, EEPROM, and flash memory. Volatile memory includes RAM. The control program is stored in the non-volatile memory of the control unit, and information on the first braking force used in the two braking processes, information on the second braking force, and data such as timers are stored in four braking modes. stored accordingly. The non-volatile memory of the control unit also stores setting values such as the reference tension and the starting tension of the tension in each braking mode.

The control unit is connected to a rotation state detection unit 52X and a mode knob position sensor for detecting the rotation position of the mode knob 84G. The gate of each FET of the switch element 84C is connected to the control section. The control section controls the switch element 84C of the braking unit 84 on and off by a PWM (Pulse Width Modulation) signal with a period of 1/1000 second, for example, according to the input from the rotational state detection section 52X and the mode knob position sensor and the control program. do. In the selected braking mode, the controller controls the switching element 84C on and off with a duty ratio that decreases according to the rotational speed. Power is supplied to the control unit from the power supply unit 54X. Preferably, the control unit detects that the tackle is on the water, and when the tackle is on the water, notifies the angler of the fact that the tackle is on the water by generating a sound from the notification device. inform.

For example, the control unit includes a spool control unit, a tension detection unit, a water landing determination unit, and a water landing notification unit as functional configurations realized by software. The spool control unit performs braking processing. The tension detector calculates the tension of the fishing line L. FIG. The tension detector calculates the tension of the fishing line L, for example, according to information about the force applied to the spool shaft 82D. The landing determination section has a non-acceleration state determination section, a non-acceleration time determination section, and a speed determination section as functional configurations. The non-acceleration state determination unit determines a non-acceleration state in which the spool 82 is not accelerating. The non-accelerated state includes a constant speed rotation state and a deceleration rotation state. The non-acceleration state determination section determines the non-acceleration state based on the time-series output of the rotational state detection section 52X. The non-acceleration time determination unit determines whether or not the non-acceleration state continues for a predetermined time. The predetermined time is, for example, 0.05 seconds to 0.5 seconds. The speed determination unit determines whether or not the rotation speed of the spool 82 has reached a very low end speed, which is a criterion for determining the landing state. When the water-landing determination unit determines that the tackle is in the water-landing state, the water-landing notification unit sets the frequency of the duty control to a frequency in the audible range, and notifies that the tackle is in the water-landing state. That is, the notification is given by generating a duty control sound.

In this embodiment, the storage element 54Y includes, for example, an electrolytic capacitor. Storage element 54Y is connected to a rectifier circuit. The rectifier circuit is connected to the switch element 84C. The rectifier circuit converts alternating current from a braking unit 84 having a rotor 84A and a coil 84B and functioning as a generator into direct current, stabilizes the voltage, and supplies it to the storage element 54Y. In this embodiment, the power supply section 54X further includes a braking unit 84 and a rectifying circuit.

For example, the rectifier circuit and storage element 54Y are mounted on the circuit board 82P. Each part including the coil 84B mounted on the circuit board 82P is covered with an insulating film 82Q made of a synthetic resin insulator. The insulating coating 82Q is formed in a cylindrical shape with a flange. The insulating coating 82Q covers the coil 84B, the circuit board 82P, and the electrical components attached to the circuit board 82P. A light emitting/receiving portion of the rotational state detecting portion 52X is exposed from the insulating coating 82Q.

When casting, the angler pushes the clutch lever 86D downward to bring the clutch mechanism 92 into the clutch-off state. In the clutch-off state, the spool 82 is in a free-rotating state, and when casting, the fishing line L is vigorously drawn out from the spool 82 by the weight of the tackle. When the spool 82 rotates by casting, the magnet rotates the inner peripheral side of the coil 84B, and when the switch element 84C is turned on, current flows through the coil 84B and the spool 82 is braked. During casting, the rotational speed of the spool 82 rapidly increases, and after passing the peak, it gradually decelerates.

Since the duty control sound is generated when the tackle reaches the water, the angler can determine that the tackle has landed on the water. The angler who has determined that the tackle has landed on the water rotates the handle 80 in the line winding direction, puts the clutch mechanism 92 in the clutch-on state by the clutch return mechanism, palms the case 86, and waits for a bite.

A general brake control operation of the control unit during casting will be described.
When casting is started and power is supplied from the power supply unit 54X to the control unit, the first initial braking force, the second initial braking force, the magnification, the damping rate, and the timer value are set in the control unit. be. The first initial braking force, the second initial braking force, the magnification, the damping rate, and the timer value are set in the controller according to the position of the mode knob 84G. The first initial braking force is the braking force in the first braking process according to the braking mode. The second initial braking force is the braking force in the second braking process. The magnification is the magnification of the second braking force. The magnification of the second braking force is, for example, within the range of 1.2 times to 2.5 times. The damping rate is the damping rate of the second braking force. The damping rate of the second braking force is included in the range of 0.2 to 0.6, for example. The timer value is the timer value of the timer during correction braking. The timer value of the timer during corrective braking is, for example, within the range of 0.05 seconds to 0.5 seconds. In addition, at least one of a reference tension for comparison with the detected tension and a start tension for determining the braking start point is also set in the controller. The multiplier of the second braking force is, for example, 1.5.

The tension is calculated according to the output of the strain gauge 46X provided on the spool shaft 82D.
If a large braking force is applied when the tension that gradually descends from the start of casting falls below a predetermined value (starting tension), the attitude of the tackle reverses before the peak rotation speed and the tackle flies stably. The control section performs the following control in order to brake before the peak rotation speed and fly the tackle in a stable attitude. That is, the control unit performs the first braking process in which a strong braking force is applied for a short period of time at the beginning of casting to reverse the tackle. Following the first braking process, the gradually weakening first braking force and the second braking force are combined to gradually brake, and the spool 82 is braked until it is determined that the tackle has landed on the water. The first braking force decreases in proportion to the square of the rotation speed from the braking force at the start of braking. The second braking force decreases at a set attenuation rate from an initial value obtained by multiplying the first braking force by a predetermined factor.

The spool control unit performs two braking processes, a first braking process and a second braking process. In the second braking process, the spool control unit compares the detected tension with the reference tension set so that at least part of it decreases with time, and when the detected tension becomes equal to or less than the reference tension, the second braking force to brake the spool 82. The second braking force is obtained by increasing the first braking force, and is damped according to the damping rate. Specifically, when the detected tension becomes equal to or less than the reference tension, a timer (N: 1, 2, 3...) operates each time the detected tension becomes equal to or less than the reference tension. brakes with a second braking force increased with reference to the first braking force when the detected tension is equal to or less than the reference tension. Note that if the detected tension exceeds the reference tension before the time expires, the timer is reset, and processing for increasing the second braking force based on the first braking force is not performed. That is, the tension attenuates according to the attenuation rate until the detected tension exceeds the reference tension before the time expires.

When judging that the tackle has landed on the water, the spool control unit instantaneously increases the braking force and judges whether or not the tackle has landed on the water based on the rotational speed of the spool 82 after the braking is released. Since the spool control unit determines whether or not the terminal tackle is in the water-landing state based on the rotational speed of the spool 82 after braking is released, if the reel 76 is an electrically controllable dual-bearing reel, the brake unit 84: The spool control unit can accurately determine whether the terminal tackle lands on the water.

When the spool control unit determines that the tackle is in the water, the spool control unit generates a duty control sound to notify the angler that the tackle is in the water. Even if it is not possible, the angler can recognize the landing of the tackle. Since the angler can recognize that the tackle has landed on the water even if he/she cannot see the tackle on the water during night fishing or the like, the angler can timely perform the thumbing operation and the clutch-on operation after landing on the water.

The controller is connected to, for example, a radio receiver. The wireless receiving device is configured to wirelessly communicate with the wireless communication unit 50Y, for example. The radio receiving device receives information about the force exerted on the spool shaft 82D output from the radio communication unit 50Y, and transmits the information to the control unit. The controller calculates the tension according to the information about the force applied to the spool shaft 82D received by the wireless receiver.
