Problems to be solved by the invention

In an electric reel as shown in patent document 1, if a sensor for detecting a handle rotation is mounted on a handle side body of a reel body that houses a clutch return mechanism, the length of a drive gear shaft increases. Therefore, the handle-side body bulges toward the handle side, which results in a problem of an increase in size. If the handle-side body is enlarged, the handle position is separated from the fixed position of the fishing rod, and there is a possibility that the balance of the weight of the left and right parts of the dual-bearing reel is broken and the operability is lowered, so there is room for improvement in this point.

Further, since the position of the detected portion such as the magnet detected by the sensor rotates together with the drive gear shaft, it is necessary to arrange the position so that the rotational resolution can be ensured.

The present invention has been made in view of such circumstances, and an object thereof is to provide an electric reel in which a sensor and a detected portion can be efficiently disposed in a reel body on a handle side, and in which an increase in the size of the reel body in the axial direction can be suppressed, and which can be operated with good operability.

Means for solving the technical problems

(1) An embodiment 1 of the present invention is an electric reel for fishing with an auxiliary motor, comprising: a reel body having a frame for rotatably supporting the spool and a cover for covering a handle side of the frame; a drive gear shaft having one end rotatably supported by the reel body and the other end rotatably supported by the cover portion, and rotated by a handle; a motor provided in the reel body and assisting rotation of the drive gear shaft, the motor comprising: a drive gear which is provided on the drive gear shaft and transmits rotation to the spool; a detection section disposed between the drive gear and the frame in an axial direction of the drive gear shaft, the detection section being rotatable together with the drive gear shaft; and a sensor provided at a position corresponding to the detected portion, for detecting rotation of the drive gear shaft.

According to aspect 1 of the electric reel of the present invention, in the case where the sensor for detecting the rotation of the drive gear shaft is provided in the reel body on the handle side, the detected portion and the sensor are disposed between the drive gear and the frame, and the detected portion is attached to the member that rotates together with the drive gear shaft, so that the length in the axial direction of the reel body on the handle side can be suppressed to be small. Accordingly, the entire reel can be reduced in size as compared with the conventional electric reel, and deterioration of operability due to breakage of the left and right weight balance of the electric reel can be suppressed.

In addition, in the present embodiment 1, the position of the detection target portion detected by the sensor may be disposed at a position that rotates together with the drive gear shaft in the axial direction at a position closer to the frame than the drive gear. Therefore, the rotation detection device can be disposed at a position where the rotation detection device can ensure the resolution of the rotation detection device without interference by the drive gear.

(2) In the electric reel according to embodiment 1 of the present invention, it is preferable that the detection target portion is provided in plural at intervals in the circumferential direction of the drive gear shaft.

In this case, the plurality of detected portions are provided at intervals in the circumferential direction of the drive gear shaft, so that the detection accuracy of the rotation amount, the rotation angle, and the like detected by the sensor can be further improved.

(3) In the electric reel according to claim 3 of the present invention, it is preferable that the electric reel according to claim 1 or 2 further includes a gear portion that is provided between the drive gear and the frame and rotates together with the drive gear shaft, the detection target portion is provided in a plurality of portions at intervals in a circumferential direction on an end surface of the gear portion facing the frame, and the sensor is disposed on the frame side of the gear portion.

In this case, the detected portion is disposed in the gear portion located between the drive gear and the frame, and the sensor is disposed closer to the frame than the gear portion, so that the detected portion and the sensor can be effectively disposed in the reel body on the handle side. Thus, the length of the handle-side reel body in the axial direction can be reliably reduced, and the whole reel can be miniaturized as compared with a conventional electric reel.

(4) In the electric reel according to any one of aspects 1 to 3, the gear portion may be a one-way clutch that restricts rotation of the drive gear shaft in one direction.

In this case, the detected portion is attached to the one-way clutch that is located between the drive gear and the frame and rotates together with the drive gear shaft, so that the detected portion and the sensor can be more effectively arranged. Thus, the length of the handle-side reel body in the axial direction can be reliably reduced, and the whole of the reel can be miniaturized as compared with a conventional electric reel.

(5) In the electric reel according to any one of aspects 1 to 4, it is preferable that the electric reel according to aspect 5 of the present invention further includes a clutch for switching between a transmission state for transmitting rotation from the handle to the spool and a cut-off state for cutting off rotation from the handle to the spool, and the gear portion is a switching portion for switching the clutch from the cut-off state to the transmission state based on rotation of the drive gear shaft.

In this case, the detected portion is attached to the switching portion that is located between the drive gear and the frame and rotates together with the drive gear shaft, so that the detected portion and the sensor can be more effectively arranged. Thus, the length in the axial direction of the reel body on the handle side can be reliably reduced, and the whole of the reel can be miniaturized as compared with a conventional electric reel.

(6) In the electric reel according to any one of aspects 1 to 5, the sensor is preferably provided in the frame.

In this case, the space for attaching the sensor to the frame can be ensured to be large, and it becomes easy to dispose the sensor at a position corresponding to the detection target portion in the frame.

In this case, the sensor is directly disposed on the frame, so that the axial length of the reel body on the handle side can be more reliably reduced.

(7) In the electric reel according to any one of aspects 1 to 6, the detected portion is preferably disposed at an end portion of the drive gear shaft on the frame side, and the sensor is preferably disposed at an opposing portion opposing the detected portion.

In this case, the detection target portion and the sensor are disposed so as to face each other in the axial direction, and therefore the rotation of the detection target portion can be detected with higher accuracy by the sensor.

(8) In the electric reel according to any one of aspects 1 to 7, the detection target portion is preferably disposed on an axial end surface of the end portion in an axial direction, and the sensor is preferably disposed on an opposing surface portion of the frame opposing the detection target portion.

In this case, even when it is difficult to attach the detection target portion to the member that rotates together with the drive gear shaft, the detection target portion can be disposed on the shaft end surface of the drive gear shaft, and the rotation amount or the rotation angle can be detected with high accuracy by the sensor provided at the position on the frame side facing the detection target portion.

(9) In the electric reel according to any one of aspects 1 to 8, it is preferable that the sensor detects a rotation angle of the detection target portion per a predetermined unit time.

In this case, the rotation angle of the predetermined unit time, which is detected by the sensor detecting the detected portion rotating together with the drive gear shaft, can be fed back to the motor, and the operation of the handle can be assisted by the power of the motor.

(10) In the electric reel according to any one of aspects 1 to 9, the aspect 10 of the present invention preferably includes a control unit that controls the output of the motor based on a detection result detected by the sensor.

In this case, the output of the motor is appropriately controlled by the control unit based on the detection result of the detection unit that detects rotation together with the drive gear shaft by the sensor, and the operation of the handle can be assisted by the power of the motor by feeding back the detection result to the motor.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the electric reel of the present invention, the sensor and the detected portion can be efficiently disposed in the reel body on the handle side, and the reel body can be prevented from being enlarged in the axial direction and can be operated well.

The term "left-right direction" in the following description refers to a left-right direction when viewed from a person holding a fishing rod having the electric reel 1 at the time of fishing. In the present embodiment, the handle 20 is located on the right side of the reel body 10.

< handle >

The handle 20 has: the crank arm 21 is non-rotatably attached to a shaft distal end portion 41b of a drive gear shaft 41 (described later) protruding to the right side of the reel body 10, and the handle grip 22 is rotatably attached to an end portion of the crank arm 21 opposite to the shaft distal end portion 41b about an axis perpendicular to the crank arm 21.

< reel body >

The reel body 10 has a frame 11 supporting the spool 30, a right cover 12 covering the handle side on the right side of the frame 11, and a left cover 13 covering the left side of the frame 11. The frame 11 includes a right side plate 11A and a left side plate 11B arranged at predetermined intervals in the left-right direction, and a plurality of connecting members 11C connecting the right side plate 11A and the left side plate 11B.

The right cover 12 is detachably provided to the right side plate 11A so as to cover the outer side of the right side plate 11A from the right side. The left cover 13 is detachably provided to the left side plate 11B so as to cover the outside of the left side plate 11B from the left side. Storage spaces S1, S2 for storing various mechanisms described later are formed between the right side plate 11A and the right cover 12, respectively. The right cover 12 has a concave shape opening to the left.

Here, the portion of the reel body 10 on the side of the handle 20 (the right side plate 11A and the right cover 12) where the storage space S1 is formed is referred to as a right-side reel body 10A.

The right reel body 10A has a substantially elliptical shape that bulges outward in the axial direction about the mounting portion of the drive gear shaft 41 in the right side plate 11A as viewed from the side. The left side plate 11B and the left cover 13 are circular in side view.

As shown in fig. 1, the plurality of connecting members 11C are plate-like members extending in the left-right direction and integrally formed with the right side plate 11A and the left side plate 11B. Each connecting member 11C connects the right side plate 11A and the left side plate 11B at three positions of the upper part, the lower part, and the rear part of the reel body 10. In the electric reel 1, by providing the coupling member 11C, even when a large load acts on the reel body 10, deformation such as deflection is less likely to occur, and a decrease in winding efficiency can be suppressed. The rod attachment portion 18 is fixed to the lower connecting member 11C. The rod attachment portion 18 is a portion to which the fishing rod is attached, and extends in the front-rear direction at a position substantially intermediate the right side plate 11A and the left side plate 11B. The rear coupling member 11C is provided with a clutch operation unit 14.

As shown in fig. 2 and 3, a right fixing plate 11D disposed in the storage space S1 is fixed to the right side plate 11A. The right fixing plate 11D is attached with a part of various mechanisms disposed in the storage space S1 inside the right reel body 10A. The right fixing plate 11D has a main body plate 110 and a shaft support recess 111 that rotatably supports a shaft base end portion 41a (1 st end portion) of the drive gear shaft 41 to which the handle 20 is coupled. The shaft support concave 111 protrudes from the body plate 110 toward the handle in the lateral direction, and is formed in a cylindrical shape that opens to the right. The right fixing plate 11D is provided with an outer peripheral tube 113 outside the shaft support concave 111 at a distance.

As shown in fig. 1 and 2, the spool 30 for winding is disposed between the right side plate 11A and the left side plate 11B, and is rotatably supported by the right side plate 11A and the left side plate 11B. A horizontal winding mechanism (not shown) for uniformly winding the fishing line around the spool 30 and the clutch operating portion 14 are disposed between the right side plate 11A and the left side plate 11B.

The clutch operation unit 14 swings vertically, and is provided to switch the clutch mechanism 50 (see fig. 3) between a clutch on state and a clutch off state.

The motor 15 is provided inside the reel body 10, and assists the rotation of the drive gear shaft 41. The motor 15 is controlled by the control unit, and is configured to be driven to rotate in the wire winding direction together with the spool 30.

As shown in fig. 3, a rotation transmission mechanism 40 for transmitting torque of the handle 20 to the spool 30 and a clutch mechanism 50 provided in the rotation transmission mechanism 40 are disposed in the accommodation space S1 between the right side plate 11A and the right cover 12. Further, a clutch control mechanism (not shown) for controlling the clutch mechanism 50 according to the operation of the clutch operation unit 14 shown in fig. 1, a traction mechanism, and a throwing control mechanism (not shown) as a braking mechanism for adjusting the resistance at the time of rotation of the spool 30 are disposed in the housing space S1. These clutch control mechanism, traction mechanism, and throwing control mechanism are well-known structures, and therefore detailed description thereof is omitted here.

As shown in fig. 1, a counter box 17 fixed to the right side plate 11A and the left side plate 11B is provided at the upper portion of the reel body 10. The counter box 17 is provided with a display unit 171 for displaying the water depth, an operation switch 172 used for various settings of the electric reel 1, and the like. A control unit, not shown, for performing various controls of the electric reel 1 is housed in the counter box 17.

< spool >

The spool 30 has: a cylindrical winding body 301 around which the fishing line is wound, and a pair of left and right flange portions 302. The flange portions 302 integrally protrude outward in the radial direction at both ends of the winding body 301. The spool 30 is rotatably supported by the right side plate 11A and the left side plate 11B on the left and right sides of the frame 11 via bearings.

< Clutch mechanism >

As shown in fig. 3, the clutch mechanism 50 includes a clutch claw and a clutch cam, not shown, and transmits and cuts off rotation from the handle 20 transmitted through a drive gear 42, which will be described later, to the spool 30. The state in which rotation from the handle 20 is transmitted to the spool 30 is a clutch-on state, and the state in which rotation from the handle 20 is cut off is a clutch-off state. In the clutch-off state, the spool 30 is in a freely rotatable state, and the fishing line can be released.

< rotation transmitting mechanism >

Next, the rotation transmission mechanism 40 will be specifically described with reference to fig. 3.

The rotation transmission mechanism 40 has a function of restricting torque when torque is reversely transmitted from the spool 30 to the handle 20 side. The rotation transmission mechanism 40 includes: a drive gear shaft 41 of the handle 20, a drive gear 42 coupled to a shaft base end 41a of the drive gear shaft 41, and a pinion (not shown) engaged with the drive gear 42 are fixed to the shaft tip end 41b (2 nd end).

The drive gear shaft 41 is disposed in the right reel body 10A, that is, on the right side of the right side plate 11A. The drive gear shaft 41 extends in the left-right direction, penetrates the top surface 121 of the right housing 12 in the axial direction, and the star-shaped traction member 3 and the handle 20 are disposed at the penetrating shaft end portion 41 b. The drive gear shaft 41 corresponds to a handle shaft, and is disposed in the left-right direction, that is, in parallel with the axial direction of the spool 30. The drive gear shaft 41 is rotatably inserted through a cylindrical body 44 fixed to the right housing 12 via a roller clutch 60 at a central portion in the axial direction.

Here, the longitudinal direction (the direction extending in the left-right direction) of the drive gear shaft 41 is hereinafter referred to as the axial direction.

The retainer 61, the stopper gear 62, the drive gear 42, and the roller clutch 60 are arranged in this order from the shaft base end portion 41a to the shaft tip end portion 41b on the drive gear shaft 41. Further, on the shaft distal end portion 41b side of the drive gear 42, a plurality of traction washers and plate washers made of thin metal plates are arranged in a state of overlapping in the axial direction, and are provided so as not to be rotatable with respect to the drive gear shaft 41. The rotation transmission mechanism 40 transmits rotational power from the handle 20 to the spool 30 by friction force of the traction washer, thereby exhibiting traction performance.

In the electric reel 1 configured as described above, the power from the handle 20 is transmitted in the order of the handle 20, the drive gear shaft 41, the traction washer, the drive gear 42, a pinion gear (not shown), and the spool 30 (the clutch is in the on state). When the fishing line is strongly pulled in the paying-out direction, a force that increases the pressing force (friction force) of the pulling is applied to the drive gear 42, that is, the force is applied in the order of the spool 30, the pinion gear, and the drive gear 42. At this time, the line is released by sliding between the drive gear 42, the drag washer, and the plate washer.

The shaft base end portion 41a of the drive gear shaft 41 is attached to the convex portion 112 of the right fixed plate 11D. The drive gear shaft 41 has a shaft base end portion 41a rotatably supported by a shaft support recess 111 of the right fixed plate 11D via a bearing 63, and a shaft tip end portion 41b rotatably supported by a top surface 121 of the right cover 12 via a roller clutch 60. The shaft distal end portion 41b is coupled to the handle 20. The outer diameter of the shaft base end portion 41a is larger than the outer diameter of the shaft portion other than the shaft base end portion 41a in the drive gear shaft 41.

The drive gear 42 has a gear on the outer periphery, which meshes with the pinion gear. The drive gear 42 is fixed to the shaft distal end portion 41b side of the drive gear shaft 41 on the handle side of the retainer 61, and is coupled to rotate integrally with the rotation of the drive gear shaft 41. The pinion constitutes the rotation transmitting mechanism 40 and functions as a clutch mechanism 50. With this configuration, the drive gear 42 transmits torque caused by the rotation of the handle 20 to the spool 30 in the clutch-on state.

Here, the bearing 63 that rotatably supports the shaft base end portion 41a of the drive gear shaft 41 is fitted into the shaft support recess 111 formed in the right fixing plate 11D. A hole 41c having a circular cross section and opening to the bottom surface of the shaft support recess 111 is formed in the center of the end surface of the shaft base end 41a of the drive gear shaft 41. At the center of the concave bottom of the shaft support concave portion 111, the convex portion 112 extends rightward. The hole 41c of the drive gear shaft 41 engages with the boss 112.

The roller clutch 60 is fitted into a through hole 121a provided in the top surface 121 of the right housing 12, and restricts rotation of the drive gear shaft 41 in one direction. The roller clutch 60 restricts rotation of the drive gear shaft 41 in a direction opposite to the wire winding direction. The roller clutch 60 has an outer race and a plurality of rolling elements. The outer ring is non-rotatably attached to the through hole 121a of the right cover 12. The outer ring has a cam surface, not shown, on its inner peripheral surface. The plurality of rolling elements are cylindrical and are arranged between the inner peripheral surface of the outer ring and the outer peripheral surface of the drive gear shaft 41. The plurality of rolling bodies allow the rotation of the drive gear shaft 41 in the wire winding direction. The roller clutch 60 may have an inner ring fixed to the outer peripheral surface of the drive gear shaft 41.

The retainer 61 restricts the movement of the drive gear shaft 41 in the axial direction of the drive gear shaft 41 with respect to the right-side reel body 10A. The holder 61 is fixed to the right fixing plate 11D by screws or the like.

The stopper gear 62 (gear portion, switching portion, one-way clutch) is disposed between the drive gear 42 and the holder 61 at the shaft base end portion 41a of the drive gear shaft 41 in a state in which movement in the axial direction to the handle 20 side is restricted. The stopper gear 62 is fixed in a non-rotatable state with respect to the drive gear shaft 41, and is rotatable together with the drive gear shaft 41. The clutch pawls and clutch cams, not shown, of the clutch mechanism 50 are disposed at substantially the same positions as the stopper gears 62 in a side view in a direction perpendicular to the axial direction of the drive gear shaft 41.

As shown in fig. 4 and 5, a plurality of convex locking teeth 621 are provided on the outer peripheral edge of the locking gear 62 at intervals in the circumferential direction. The clutch pawls of the clutch mechanism 50 can engage with a plurality of engagement teeth 621. The stopper gear 62 switches the clutch mechanism 50 from the cut-off state to the transmitting state based on the rotation of the drive gear shaft 41. The stopper gear 62 is non-rotatably fixed to the drive gear shaft 41, and rotates together with the drive gear shaft 41. The stop gear 62 restricts rotation in one direction by the clutch pawls of the clutch mechanism 50. Therefore, the stopper gear 62 restricts the rotation of the drive gear shaft 41 in one direction. As described above, the stopper gear 62 of the present embodiment has a function as a return gear.

As shown in fig. 3 and 5, a plurality of magnets 71 (detected portions) are provided at intervals (here, 6) in the circumferential direction around the axis of the drive gear shaft 41 on one end surface 62a of the stopper gear 62 facing the right fixed plate 11D (right side plate 11A). The plurality of magnets 71 are positioned such that the distance in the radial direction from the axial center of the drive gear shaft 41 substantially coincides with the distance from the axial center in the sensor 72 described later, and the magnets 71 rotating together with the stopper gear 62 can face each other in the axial direction with respect to the sensor 72.

The magnet 71 rotates together with the rotation of the stopper gear 62, that is, the rotation of the drive gear shaft 41. The magnet 71 is disposed between the drive gear 42 and the right fixed plate 11D as the frame 11 in the axial direction, and is provided so as to be rotatable together with the drive gear shaft 41. The magnet 71 is detected by a sensor 72 provided at a position opposed to the stopper gear 62.

The sensor 72 is provided on the right fixed plate 11D side of the stopper gear 62 and corresponds to the magnet 71. The sensor 72 is disposed in a concave portion between the shaft support concave portion 111 and the outer peripheral tube 113 in the right fixed plate 11D of the frame 11. The sensor 72 detects the rotation angle of the magnet 71 per predetermined unit time, that is, the rotation of the drive gear shaft 41. Then, based on the detection result detected by the sensor 72, the output of the motor 15 is controlled by a control unit (not shown).

Next, the operation of the electric reel 1 configured as described above will be described in detail with reference to the drawings.

In the electric reel 1 of the present embodiment, as shown in fig. 3, when the sensor 72 for detecting the rotation of the drive gear shaft 41 is provided in the right-side reel body 10A, the length in the axial direction of the right-side reel body 10A can be suppressed to be small by disposing the magnet 71 and the sensor 72 between the drive gear 42 and the right-side fixing plate 11D of the frame 11 and attaching the magnet 71 to a member that rotates together with the drive gear shaft 41. As a result, the entire reel can be made smaller than the conventional electric reel, and the deterioration of the weight balance of the electric reel 1 can be suppressed, thereby reducing the operability.

In the present embodiment, the position of the magnet 71 detected by the sensor 72 can be arranged at a position on the right fixed plate 11D side of the drive gear 42 in the axial direction and rotated together with the drive gear shaft 41. Therefore, the rotary magnet 71 can be disposed at a position where the rotary magnet is not interfered by the drive gear 42 and the decomposing ability of the rotary magnet can be ensured.

In the electric reel 1 of the present embodiment, a plurality of magnets 71 are provided at intervals in the circumferential direction of the drive gear shaft 41. Therefore, by providing the plurality of magnets 71 at intervals in the circumferential direction of the drive gear shaft 41, the detection accuracy of the rotation amount, the rotation angle, and the like detected by the sensor 72 can be further improved.

In the present embodiment, the stopper gear 62 is provided between the drive gear 42 and the right fixed plate 11D, and is provided to rotate together with the drive gear shaft 41. The magnets 71 are provided at a plurality of intervals in the circumferential direction on an end surface 62a of the stopper gear 62 facing the right fixed plate 11D. The sensor 72 is disposed on the right fixed plate 11D side of the stopper gear 62.

Accordingly, since the magnet 71 is disposed on the stopper gear 62 located between the drive gear 42 and the right fixed plate 11D and the sensor 72 is disposed on the right fixed plate 11D side of the gear portion, the magnet 71 and the sensor 72 can be effectively disposed in the right reel body 10A. This makes it possible to more reliably reduce the length of the right reel body 10A in the axial direction, and to reduce the size of the whole reel as compared with a conventional electric reel.

In the present embodiment, the stopper gear 62 restricts the rotation of the drive gear shaft 41 in one direction. By attaching the magnet 71 to the stopper gear 62 that is located between the drive gear 42 and the right fixed plate 11D and rotates together with the drive gear shaft 41, the magnet 71 and the sensor 72 can be more effectively arranged. This makes it possible to reliably reduce the length of the right reel body 10A in the axial direction, and to reduce the size of the whole reel as compared with a conventional electric reel.

In the present embodiment, a clutch mechanism 50 is provided for switching between a transmission state in which rotation from the handle 20 to the spool 30 is transmitted and a cutting state in which rotation from the handle 20 to the spool 30 is cut off. The stopper gear 62 is a switching portion that switches the clutch mechanism 50 from the off state to the transmitting state based on the rotation of the drive gear shaft 41. Thus, by attaching the magnet 71 to the switching portion that is located between the drive gear 42 and the right fixed plate 11D and rotates together with the drive gear shaft 41, the magnet 71 and the sensor 72 can be effectively arranged. This makes it possible to more reliably reduce the length of the right reel body 10A in the axial direction, and to reduce the size of the whole reel as compared with a conventional electric reel.

In the present embodiment, the sensor 72 is provided in the right fixing plate 11D. Accordingly, the installation space for installing the sensor 72 on the right fixing plate 11D can be ensured to be large, and therefore, it becomes easy to dispose the sensor 72 on the right fixing plate 11D at a position corresponding to the magnet 71. In this case, since the sensor 72 is directly disposed on the right fixing plate 11D, the length in the axial direction of the right reel body 10A can be reliably suppressed to be small.

In the present embodiment, the magnet 71 is disposed at the end of the drive gear shaft 41 on the right fixed plate 11D side. The sensor 72 is provided at an opposing portion opposing the magnet 71. Accordingly, the magnet 71 and the sensor 72 are disposed so as to face each other in the axial direction, and therefore the sensor 72 can detect the rotating magnet 71 with higher accuracy.

In the present embodiment, the sensor 72 detects the rotation angle of the magnet 71 per a predetermined unit time. Thus, the rotation angle of the predetermined unit time detected by the sensor 72 by the magnet 71 rotating together with the drive gear shaft 41 can be fed back to the motor 15, and the operation of the handle 20 can be assisted by the power of the motor 15.

In the present embodiment, a control unit is provided for controlling the output of the motor 15 based on the detection result detected by the sensor 72. Accordingly, the detection result of the magnet 71 rotating together with the drive gear shaft 41 by the sensor 72 can be appropriately controlled by the control unit to output the motor 15, and the operation of the handle 20 can be assisted by the power of the motor 15 by feeding back the output to the motor 15.

In the electric reel 1 of the present embodiment configured as described above, the sensor 72 and the magnet 71 can be efficiently disposed in the right-side reel body 10A, and the increase in the size of the reel body 10 in the axial direction can be suppressed, so that the operability is improved.

While the embodiments of the electric reel of the present invention have been described above, these embodiments are shown by way of example and are not intended to limit the scope of the invention. The embodiments can be implemented in other various modes, and various omissions, substitutions, and changes can be made without departing from the gist of the invention. The embodiments and modifications thereof include, for example, embodiments that can be easily assumed by those skilled in the art, substantially the same embodiments, and embodiments within an equivalent range.

For example, in the present embodiment, the present invention is applied to an electric reel, but the present invention may be applied to a fishing reel other than an electric reel.

In the present embodiment, the sensor 72 is provided in the frame 11 (right fixing plate 11D), but the position of the sensor 72 is not limited to the position disposed in the frame 11. In summary, the sensor 72 may be disposed at a position between the drive gear 42 and the frame 11 and capable of detecting the position of the magnet 71 (detected portion).

In the present embodiment, the magnet 71 (the detected portion) is provided to the stopper gear 62 that rotates together with the drive gear shaft 41, but is not limited to this position. In summary, the position between the drive gear 42 and the frame 11 may be any position such as a gear portion, a switching portion, a one-way clutch, or the like, which is rotatable together with the drive gear shaft 41. That is, the position of the detected portion may be arranged on the frame side of the reset gear that rotates together with the drive gear shaft 41 instead of the stopper gear 62.

The frame defining the range in which the detected portion and the sensor are arranged in the axial direction is not limited to the right fixing plate 11D as in the present embodiment, and may be the right side plate 11A.

Further, in the present embodiment, 6 magnets 71 are provided at intervals in the circumferential direction on the end surface 62a of the stopper gear 62 facing the right fixed plate 11D, but the number of magnets 71 and the arrangement intervals in the circumferential direction can be appropriately set based on the detection result of the rotation angle or the like of the detected portion per a predetermined unit time.

In the present embodiment, the positional relationship between the detected portion and the sensor is disposed at a position facing each other in the axial direction of the drive gear shaft 41, but is not limited to such a positional relationship. In summary, the sensors may be disposed so as to face each other in a direction intersecting the axial direction, as long as the positional relationship of the detection target portion can be detected by the sensors. Alternatively, the detection unit and the sensor may not be limited to be opposed to each other.

As another configuration of the electric reel, for example, an electric reel 1A of a modification can be used. In the electric reel 1A according to the modification, the magnet 71 is disposed on the axial end surface 41D of the axial base end portion 41A of the drive gear shaft 41, and the sensor 72 is provided in the recess 114, which is the facing surface of the right fixing plate 11D facing the magnet 71. The magnet 71 of the shaft end surface 41d rotates together with the drive gear shaft 41.

In this case, even when it is difficult to attach the magnet 71 to the member that rotates together with the drive gear shaft 41, the magnet 71 can be disposed on the shaft end surface of the drive gear shaft 41, and the rotation amount or the rotation angle can be detected with high accuracy by the sensor 72 provided at the position on the right fixing plate 11D side facing the magnet 71.
