Description

  The present invention relates to a fishing reel, and more particularly, to a fishing reel that can detect a fishing line feeding and winding state with high accuracy.

2. Description of the Related Art Conventionally, a fishing reel incorporating a line length measuring device capable of detecting the amount of fishing line wound around a spool is known. In addition, a fishing reel is also known that incorporates a notification means for notifying when a fish is caught during actual fishing.
In order to measure the length of the line fed out from the spool or to detect that the fishing line has been fed out from the spool, it is necessary to provide a detection device in the spool and the driving force transmission mechanism that drives the spool.

  As described above, for example, as disclosed in Patent Document 1, the detection device as described above is a Hall IC in which a transmitter such as a magnet is attached to the outer surface of a rotating body that rotates integrally with a spool, and this is installed at a position facing it. Rotation information is obtained by detecting with a receiver such as the above. In this case, the rotation direction of the spool can be detected by installing a plurality of transmitters at equal intervals on the outer surface of the rotating body.

JP-A-10-309157

  In the conventional detection device described above, one signal is obtained when the spool makes one rotation. For example, even if three transmitters (receivers) are installed, three signals are detected by one rotation of the spool. Only a signal can be obtained. That is, assuming a spool with a diameter of 3 cm, the circumference is about 10 cm, and even if three transmitters are installed, only about 3 cm per signal can be judged.

  For this reason, for example, even if a fish is hooked and a fishing line is pulled out, it cannot be detected unless the spool is rotated for 3 cm, and a slight hit (drawing about 1 cm) cannot be detected. Moreover, since the current thread length display is limited to 10 cm units, it cannot cope with fishing that requires more accuracy (such as fish mouths, which cannot accurately feed bait). Further, in the configuration in which the speed of the spool is controlled, only a rough speed can be detected, so that the speed control that the angler wants to aim at cannot be performed.

  The present invention has been made paying attention to the above-described problems, and an object of the present invention is to provide a fishing reel capable of detecting a fishing line feeding / winding state with high accuracy.

  In order to achieve the above-described object, the present invention provides a fishing reel in which a spool is rotated by a winding operation of a handle to wind a fishing line on a rotation axis of a rotating body that rotates in conjunction with the spool. A magnet installed with a north pole and a south pole magnetized in a direction perpendicular to the axis, and opposed to the magnet, detects a change in the magnetic field of the magnet and determines the rotation angle of the rotating body. And a rotation angle detecting means including a rotation angle sensor for detecting the rotation angle.

  In the fishing reel having the above-described configuration, the rotation angle sensor of the rotation angle detection means detects a change in the magnetic field of the magnet provided on the rotation axis of the rotating body that rotates in conjunction with the spool. It becomes possible to detect the state (rotation angle) with high accuracy. For this reason, for example, even if the fishing line is slightly pulled out of the spool with a slight hit of the fish, it is possible to detect the rotation, and the length of the fed fishing line can be measured in units of 1 mm. Therefore, it is possible to drop the device onto a desired shelf with high accuracy, and furthermore, the rotation speed of the spool can be detected with high accuracy. Therefore, in the electric reel that rotates the spool by the drive motor, the motor is driven with high accuracy. The speed can be controlled.

  In addition to the above-described form, the present invention is a fish that rotates a rotor by a winding operation of a handle and moves the spool back and forth to wind the fishing line around the spool via a fishing line guide provided on the rotor. The present invention can also be applied to fishing reels. That is, the present invention is such a fishing reel that is installed on a rotating shaft core of a rotating body that rotates in conjunction with the winding operation, and has N and S poles in a direction perpendicular to the shaft core. A rotation angle detection means comprising: a magnet magnetized with a magnet; and a rotation angle sensor that is disposed opposite to the magnet and detects a rotation angle of the rotating body by detecting a magnetic field change of the magnet. It is characterized by.

  According to the present invention, it is possible to obtain a fishing reel capable of detecting a fishing line feeding / winding state with high accuracy.

Hereinafter, an embodiment of a fishing reel according to the present invention will be described with reference to the drawings.

(A) is an enlarged view of a portion where the rotation angle detecting means is disposed, (b) is a perspective view showing a magnet installation state, and (c) is an end view of the spool shaft. is there.

  A reel body 1 constituting a dual-bearing type reel includes left and right frames 2a and 2b, and left and right side plates 3a and 3b mounted on the left and right frames 2a and 2b with a predetermined space, respectively, via a sealing material. . The left and right frames 2a and 2b are integrated with each other through a plurality of support columns, and the lower support column 4 is provided with a reel leg 4a to be mounted on a reel seat of a fishing rod. In addition, a control case 200 including a display unit (not shown) capable of displaying various types of information is provided on the upper side of the left and right frames 2a and 2b facing the lower columns.

  A spool shaft 5 is rotatably supported between the left and right frames 2a and 2b (left and right side plates 3a and 3b) via bearings 6a and 6b, and a spool around which a fishing line is wound. 5a is attached. In this case, the bearing 6a is disposed in the annular recess 3c formed inside the left side plate 3a to support one of the spool shafts 5, and the bearing 6b is disposed in the through hole 2c formed in the right frame 2b. It is provided and supports the other side of the spool shaft 5.

  The bearing 6a that rotatably supports the spool shaft 5 is abutted against a step 3d formed on the inner surface of the annular recess 3c to prevent the outer ring side from coming off, and the inner ring side is installed on the spool shaft 5. It is attached to the washer 6d and is prevented from coming off. In the present embodiment, the rotation angle detection means 100 for detecting the rotation state of the spool 5a is disposed on the tip side of the bearing 6a.

  A handle shaft 8 is disposed between the right frame 2b and the right side plate 3b. The handle shaft 8 is rotatably supported by the right frame 2b via a bearing 9, and The rolling type one-way clutch 10 (reverse rotation prevention mechanism) interposed between the two can rotate only in the fishing line winding direction. The end portion of the handle shaft 8 protrudes from the right side plate 3b, and the handle 11 is attached to that portion. The handle 11 is provided with a lever 11b having a handle knob 11a attached to the tip thereof. The base end of the lever 11b is attached to the handle shaft 8, and the knob 5a is gripped and rotated to operate the spool 5a. Is designed to rotate.

  Between the right frame 2b and the right side plate 3b, a driving force transmission mechanism for rotating the spool shaft 5 by winding operation of the handle 11 and winding the fishing line around the spool 5a, and transmission of this driving force are continued. A clutch mechanism that disengages and a braking device that applies a drag force to the spool 5a when the fishing line is fed out from the spool 5a during fishing are housed.

  The drive force transmission mechanism includes a drive gear 12 rotatably supported on the handle shaft 8 and a pinion 13 that meshes with the drive gear 12. In this case, the pinion 13 extends integrally with the spool shaft 5 and is provided on the pinion shaft 5b rotatably supported by the right side plate 3b via the bearing 15, and the pinion 13 extends along the pinion shaft 5b. It can move in the direction. In addition, a circumferential groove is formed on the outer periphery of the pinion 13, and the operating member 16 of the clutch mechanism is engaged with the circumferential groove, and the driving force is continuously transferred by moving the pinion 13 in the axial direction. It has come to be. That is, a fitting portion is formed at the end of the pinion 13, and the pinion 13 is moved to the spool side by the operating member, and the fitting portion is formed at the end of the spool shaft. When the engagement portion 5c is engaged, the driving force is transmitted (clutch ON state), and the pinion 13 is moved to the right side plate by the operating member, so that the engagement portion is disengaged from the engagement portion 5c. A driving force non-transmission state (clutch OFF state) is established.

  The clutch mechanism has a clutch operation plate 20 slidably disposed along the right frame 2b, and an operation lever (switching operation member) 30 protruding from the reel body so as to drive the clutch operation plate. is doing. The switching operation member 30 has a support shaft 30a inserted and supported from the right side plate side toward the right frame, and is inserted into a long hole 20a formed in the clutch operation plate 20 at the tip. An operating body 30b having a mating pin 30c is fixed to prevent rotation.

  The clutch operating plate 20 drives the operating member 16 fitted in the circumferential groove of the pinion 13 to move the pinion 13 in the axial direction as the switching operation member 30 rotates. FIG. 1 shows a clutch ON state in which the pinion 13 is engaged with an engagement portion 5c formed at the end of the spool shaft. When the switching operation member 30 is rotated in this state, the pinion 13 is shown. Is moved to the right by the actuating member 16 and is disengaged from the engaging portion 5c formed at the end of the spool shaft, and the clutch is turned off.

  Further, the braking device is configured by a so-called multi-plate braking system in which a plurality of friction plates 32 are accommodated in a recess formed in the drive gear 12, and an adjustment attached to the end of the handle shaft 8. By rotating the member 33, the pressing force against the friction plate is increased or decreased, thereby applying desired braking to the rotation of the spool 5a in the fishing line feeding direction.

  As the rotation angle detection means 100, one that can accurately detect the rotation state (rotation angle) of the spool 5a is used, and is installed on the rotation axis X of the spool shaft 5 that rotates integrally with the spool. And a magnet 101 with N and S poles magnetized in a direction orthogonal to each other, and a rotation angle sensor 102 that is arranged to face the magnet 101 and detects a rotation angle of the spool shaft 5 by detecting a magnetic field change of the magnet 101. And. The rotation angle sensor 102 is also installed on the rotation axis X of the spool shaft 5.

The rotation angle sensor 102 described above is installed in a recess 3e formed at the bottom of an annular recess 3c formed in the left side plate 3a, and the control case is connected via a lead wire 105 installed in the left side plate. It is connected to a control board in 200.
The rotation angle sensor 102 is a sensor (for example, a linear Hall IC) capable of detecting a change in magnetic field over 360 ° when the magnet 101 is rotated, and a voltage change signal (sine curve) corresponding to the change in the magnetic field. As an analog signal). The analog signal thus obtained becomes a voltage displacement signal that has been AD-converted in the control board, and is subjected to arithmetic processing according to a predetermined program to obtain the rotation angle of the magnet 101 (spool shaft 5) with high accuracy. It is possible to do.

  The rotation angle sensor that detects the rotation angle of the spool shaft 5 can detect the fine angle by changing the sensitivity of the output voltage. For example, by using an angle detection device disclosed in Japanese Patent Application Laid-Open No. 2010-217151. The rotation angle of the spool shaft 5 in units of 0.5 ° can be detected. Therefore, according to such an angle detection device, 720 detection signals can be acquired per rotation of the spool 5a, and the rotation state (rotation speed, rotation direction) of the spool can be acquired with high accuracy. It becomes possible to do.

  The magnet 101 described above can be a bar magnet magnetized with N poles and S poles on both sides, and such a magnet 101 is installed on the rotational axis X of the spool shaft 5 as described above. The N pole and the S pole are arranged in a direction orthogonal to the axis. The material of the magnet 101 is not particularly limited, but it is preferable to use a rare earth material because a strong magnetic field can be obtained. Further, although the length depends on the diameter of the spool shaft 5, it is preferable to use one having a diameter or less. Further, as in this embodiment, the end surface 5 e of the spool shaft 5 has a groove 5 f extending in the radial direction. It is preferable to form and fix in this groove by bonding or the like.

  Thus, by using a magnet 101 having a diameter smaller than that of the spool shaft 5 and fixing it in the groove 5f formed on the end surface of the spool shaft, the magnet 101 can be easily mounted on the spool shaft, and the bearing 6a. Can be easily installed and replaced.

  By installing the rotation angle detection means 100 as described above, the rotation state of the spool 5a can be detected with higher accuracy. For example, as described above, assuming a spool with a diameter of 3 cm and using a rotation angle sensor with a detection angle of 1 ° unit, 360 signals can be obtained in one round, and the conventional three transmitters can be obtained. Compared with the configuration in which three signals are obtained in one round, it is possible to acquire data 100 times or more. That is, since the circumference of the spool having a diameter of 3 cm is about 10 cm, it is possible to determine the fishing line withdrawal of about 0.25 mm in consideration of the withdrawal of the fishing line.

  Therefore, since the detailed rotation state of the rotating spool 5a can be detected with higher accuracy than in the conventional configuration, for example, even if the fishing line is slightly pulled out of the spool 5a with a slight hit of the fish, It becomes possible to detect the rotation, and the fish sensitivity can be improved. For example, based on the detection signal, the fisherman can be alerted to the fisherman on the control board side with a sound, a visible display, etc., so that the fisher can grasp a slight fish attack It becomes possible to make it.

  Further, since the above-described rotation angle detecting means 100 can measure the feeding of the fishing line from the spool in units of 1 mm, the display portion of the control case 200 conventionally displays only up to 10 cm units. The feed amount can be displayed in millimeters. As a result, the fisherman can accurately drop the device on a desired shelf, particularly on the mouth of the migrating fish. As for the fishing line feeding from the spool, although the winding diameter of the fishing line changes according to the feeding amount, the correct feeding amount is displayed by performing a correction process with a known arithmetic program according to this diameter change. Is possible.

FIG. 3 is a diagram illustrating a modification of the above-described embodiment, and is a diagram illustrating a structure of a portion where the rotation angle detection unit 100 is installed.
In the embodiment described above, the rotating body that rotates integrally with the spool 5a is the spool shaft 5. However, in this modification, the driving gear 5A is installed on the spool shaft 5, and the interlocking gear 5B that meshes with the driving gear 5A is rotated. The body.

  The interlocking gear 5B is rotatably supported on the support plate by screwing a screw (support shaft) 35 serving as a rotation axis from the spool side into a support plate (set plate) 3A attached to the left side plate 3a. Has been. A magnet 101 magnetized with N and S poles in a direction perpendicular to the axis of the screw 35 is installed on the side surface facing the left side plate of the interlocking gear 5B, and the opposite left side plate. By installing the rotation angle sensor 102 at 3a, the rotation angle of the spool 5a can be detected as in the above-described embodiment. In this case, the magnet 101 may be configured to be attached to the surface corresponding to the position of the screw 35, or as shown in the figure, a recess 5B ′ is formed so that the surface is flush. In such a configuration, since the magnet is previously installed on the gear, the installation operation of the rotation angle detecting means 100 can be easily performed.

As described above, the rotating body on which the rotation angle detection means 100 is installed is an interlocking gear transmitted from the spool, and the gear ratio between the drive gear 5A and the interlocking gear 5B is appropriately set, so that the detection of the rotation angle detection means 100 is performed. The accuracy can be improved. For example, if the gear ratio is set to 4: 1, even if the detection angle is a rotation angle sensor with a unit of 4 °, if the rotation angle of the interlocking gear 5B is detected, the detection angle of the spool 5a is detected. Can be improved to 1 °.
Note that the interlocking gear 5B only needs to have a relationship that interlocks with the drive gear 5A attached to the spool shaft, and may be connected to the drive gear 5A via a gear train.

FIG. 4 is a view showing a second embodiment (double-bearing type reel) of a fishing reel according to the present invention, and is a partial sectional plan view of a portion where a rotation angle detecting means is arranged.
In the embodiment described below, the same reference numerals are given to the same components as those in the above-described embodiment, and the detailed description is omitted.

  In the present embodiment, the rotating body that rotates integrally with the spool has a different function. Usually, the reel body 1 of the double-bearing type reel is placed between the left and right frames 2a and 2b in front of the spool 5a so that the fishing line is evenly wound around the spool 5a in synchronization with the rotational drive of the spool 5a. A level wind mechanism 40 is installed.

  As is well known, the level wind mechanism 40 has a cylindrical shaft 41 installed between the left and right frames 2a and 2b, and engages with a worm shaft 42 rotatably supported in the cylindrical shaft and a spiral groove of the worm shaft 42. A sliding body 43 provided with a pin is provided, and a fishing line guide (not shown) through which the fishing line is inserted is provided on the sliding body. The fishing line guide is engaged with a support shaft 45 installed between the left and right frames 2a and 2b and is prevented from rotating, and the worm shaft 42 is driven to rotate, so that the fishing line guide is left and right in front of the spool. Reciprocatingly driven in the direction, the fishing line is evenly guided with respect to the spool 5a.

  Such a level wind mechanism 40 needs to rotationally drive the worm shaft 42 in synchronization with the rotation of the spool 5a when the handle is rotationally driven in the winding direction. In this embodiment, the spool shaft is attached to the left frame 2a. The intermediate gear 5C meshed with the drive gear 5A attached to the shaft 5 is rotatably supported, and a screw (support shaft) 46 is screwed into the end of the worm shaft 42 from the left side plate side to mesh with the intermediate gear 5C. An interlocking gear 5D is provided to drive the level wind mechanism 40.

  On the side surface facing the left side plate of the interlocking gear 5D, a magnet 101 having N and S poles magnetized in a direction orthogonal to the axis of the screw 46 is installed. In this case, the magnet 101 is provided on a convex portion 5Da (which may be an annular convex portion or a pair of convex portions capable of supporting the bar magnet on both sides) that protrudes around the mounting position of the screw 46. Thus, the rotation angle of the spool 5a can be detected by the rotation angle sensor 102 installed on the opposite left side plate 3a, as in the above-described embodiment.

  As described above, the rotating body that rotates integrally with the spool 5a may have a function other than the detection of the rotation angle of the spool, such as a gear that drives the level wind mechanism, and the place where the rotating body is installed. Is not limited.

FIGS. 5 and 6 are views showing a third embodiment (electric reel) of a fishing reel according to the present invention, FIG. 5 is a partial cross section seen from the rear, and FIG. 6 is a rotation angle detecting means. It is an enlarged view of the part by which is arrange | positioned.
The electric reel is configured to transmit the rotational driving force of the drive motor to the spool 5a via a power transmission mechanism, and normally the output of the drive motor is decelerated between the spool 5a and the spool shaft 5. As described above, a speed reduction mechanism using a planetary gear is provided. In the configuration shown in the figure, the rotational driving force from the drive motor is transmitted to the input gear 50 provided on the left side plate side of the spool shaft 5, and the spool shaft 5 to be rotationally driven is the right side plate. It is transmitted to the spool 5a via a known speed reduction mechanism 51 installed on the side.

  For this reason, the spool shaft 5 and the spool 5a are in a rotatable relationship via the bearings 52a and 52b. In order to detect the rotation state of the spool 5a, it is necessary to detect the rotation state of the spool itself. . The electric reel shown in the figure is an out-spool type in which the drive motor is installed outside the spool, but there is no spool shaft that supports the spool even in the in-spool type in which the drive motor is installed in the spool. It is necessary to detect the rotation state of the spool itself.

In the present embodiment, an internal gear 5E is provided on an end surface (left end surface) of the spool 5a, and an interlocking gear 5F serving as a rotating body is meshed with the internal gear 5E.
The interlocking gear 5F can be rotated on the support plate by screwing a screw (support shaft) 55 serving as a rotation axis from the left plate side into the support plate (set plate) 3A attached to the left plate 3a. It is supported. A magnet 101 magnetized with N and S poles in a direction perpendicular to the axis of the screw 55 is installed on the side surface facing the left side plate of the interlocking gear 5F, and the opposing left side plate A rotation angle sensor 102 is installed at 3a, so that the rotation angle of the spool 5a rotating at high speed can be detected as in the modification of the first embodiment described above. That is, for the interlocking gear that rotates integrally with the spool, in addition to the gear that meshes with the driving gear provided on the spool shaft, the driving gear (internal gear 5E) is formed on the spool itself, and the interlocking gear that is interlocked by this internal gear The gear 5F may be used.

  As described above, by installing the high-accuracy rotation angle detection means 100 on the electric reel, in addition to the effects of the above-described embodiment, the rotational drive of the drive motor is feedback-controlled according to the rotation state of the spool. This makes it possible to perform delicate rotation control of the drive motor during actual fishing. For example, when a fish is caught, the rotation of the spool 5a is detected to control the rotation speed of the drive motor so that it is in an optimal rotation state, or a slight fish or the like is accurately detected to control the drive motor. It becomes possible. Alternatively, it is possible to perform highly accurate spool drive control, such as by performing rotation control of the spool to perform fish invitation operation or shaving operation.

7 and 8 are views showing a fourth embodiment (spinning reel) of a fishing reel according to the present invention, FIG. 7 is a side view showing an internal structure, and FIG. It is sectional drawing seen from, and is an enlarged view of the part by which a rotation angle detection means is arrange | positioned.
The reel body 61 of the spinning reel according to the present embodiment is integrally formed with a reel leg 62 in which a rod mounting portion 62A is formed at a tip mounted on a fishing rod, and a rotor supported rotatably at the front thereof. 63 and a spool 65 supported so as to be movable back and forth in synchronism with the rotational motion of the rotor 63.

  The reel body 61 includes a body 61A that houses a winding drive mechanism 80, which will be described later, and a thin plate-like lid body 61B that closes an opening of the body 61A. The rotor 63 includes a pair of arm portions 63a that rotate around the spool 65, and a bail support member 63c having a base end portion of the bail 63b attached to the front end portion of each arm portion 63a. It is rotatably supported between the fishing line winding position and the fishing line discharge position. In this case, one base end portion of the bail 63b is attached to a fishing line guide portion (line roller) 63d provided integrally with the bail support member 63c.

  A handle shaft 67 is rotatably supported in the reel main body 61 via a pair of bearings 67a and 67b, and a handle 67c is attached to the protruding end on the right side. Further, a cap 67d for closing the rotation angle detecting means 100 to be described later is attached to the handle shaft 67 on the side where the handle 67c is not attached.

  A winding drive mechanism 80 is engaged with the handle shaft 67, and the winding drive mechanism 80 meshes with a drive gear 68 that is mounted on the handle shaft 67 so as to be integrally rotatable. A pinion 70 is provided as a rotational drive shaft (drive unit) having a pinion tooth portion and extending in a direction orthogonal to the handle shaft 67 and having a hollow portion extending in the axial direction therein.

  The pinion 70 is rotatably supported in the reel main body 61 by a pair of bearings 72a and 72b fitted and supported by the support portion of the reel main body 61 (body 61A) on the front side and the rear side of the pinion tooth portion, respectively. Has been. The pinion 70 extends toward the spool 65, and a rotor 63 is attached to the tip of the pinion 70 via a rotor nut so as to be integrally rotatable.

An anti-reverse rotation device (one-way clutch) 90 is mounted on the pinion 70 on the front side of the bearing 72a disposed on the front side of the pinion tooth portion, and a switching operation portion 92 provided outside the reel body 61 is provided. By rotating the handle, the reverse rotation of the handle (rotor 63) in the fishing line feeding direction is prevented.
In other words, the rotor 63 can be switched between a reverse rotation prevention state (ON state of the reverse rotation prevention device) and a reverse rotation enabled state (OFF state of the reverse rotation prevention device) by rotating the switching operation unit 92. ing.

  A spool shaft 75 extending in a direction perpendicular to the handle shaft 67 and having a spool 65 mounted on the tip side is inserted into the hollow portion formed in the pinion 70 so as to be movable in the axial direction. The spool shaft 75 is reciprocated back and forth by a known spool reciprocating device 80 driven through a power transmission gear 74 connected to the pinion 70.

  With the above-described configuration, when the handle 67c is wound up, the rotor 63 is rotationally driven via the drive gear 68 and the pinion 70, and the spool reciprocating device 80 is driven via the power transmission gear 74, whereby the spool shaft 75 (Spool 65) is reciprocated in the front-rear direction. Accordingly, the fishing line is evenly wound around the spool 5 through the fishing line guide portion 63d of the rotor 63 that is rotationally driven.

  The rotating body that rotates in conjunction with the handle winding operation is provided with a rotation angle detecting means. In this embodiment, the rotation angle detecting means 100 is provided on the handle shaft 67 that is a rotating body. . Similar to the above-described embodiment, the rotation angle detection means 100 is provided on the rotation axis of the handle shaft 67, which is a rotating body, and magnets with N and S poles magnetized in a direction orthogonal to the axis. 101 and a rotation angle sensor 102 that is disposed opposite to the magnet 101 and detects a rotation angle of the handle shaft by detecting a magnetic field change of the magnet.

The magnet 101 can be fixed to this portion by forming a groove on the end surface of the handle shaft 67, for example, as in the first embodiment. Further, the rotation angle sensor 102 is installed on a support member 110 attached to the cover body 61B, and a control box installed in the body 61A via a lead wire 105 provided from the cover body 61B to the body 61A. It is connected to the control board in 200A.
The control box 200A is connected to a display unit 210 that is incorporated so as to be exposed at the rear end surface of the body 61A. The rotation information of the handle shaft 67 is stored in a processing program for a control board in the control box 200A. Accordingly, the information is processed and various information is displayed on the display unit 210.

  According to the above-described configuration, it is possible to detect the winding state when the handle 67c is wound and the fishing line is wound on the spool 65 with high accuracy. For example, a standard winding speed pattern for each fish type and lure is input to the control board in the control box 200A, and an ideal winding state (drawing speed) is obtained along the speed pattern selected by the angler. Such information may be displayed or notified. In other words, it is possible to reliably grasp the pulling speed of the fisherman's device and control it to be in an optimum winding state.

  In the spinning reel, the rotating body that rotates by feeding out the fishing line may be the rotor 63 or the fishing line guide part (line roller) 63d in addition to the handle shaft described above. You may make it acquire the exact rotation information of a body.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to an above-described structure, A various deformation | transformation is possible.
