Description

  The present invention relates to an electric reel for fishing.

  2. Description of the Related Art Conventionally, fishing electric reels are provided with an operation member for winding a spool, that is, an operation member for continuously varying the output of a drive motor for rotating the spool. For example, in the electric reel disclosed in Patent Document 1, an operation member (adjustment member) for adjusting the output of the drive motor in accordance with the rotational position is rotatably provided on one side plate of the reel body. Such an electric fishing reel also has a display case for displaying the water depth and the like, and also includes a waterproof control case that houses a control board for controlling the drive motor.

  By the way, in Patent Document 1, the operation member is rotatably mounted on a support shaft that is erected on the outer surface of the waterproof control case, and in this mounted state, the operation member is screwed into the female screw hole of the support shaft. It is prevented from coming off by a fixing bolt. Further, in the operation member, first and second magnets are accommodated as detectors in the pair of detector accommodating portions, respectively, and these magnets are magnetized along the axial direction of the operation member.

  On the other hand, the phase detection unit that detects the rotation phase (and therefore the rotation position and the operation amount) of the operation member is located near the support shaft that supports the operation member and is mounted on the control board in the control case. This Hall element detects the rotational phase of the operating member by detecting a change in the magnetic flux direction of the first and second magnets as the operating member rotates.

  However, in the structure of Patent Document 1, since the support shaft is integrally provided as a cantilever shaft in the control case that accommodates the control board, and the operation member is attached to the support shaft, the control case is configured to operate the operation member. It is easily exposed to external forces including force and impact acting on the reel. In addition, if the waterproof control case that houses the electronic device is easily exposed to external force in this way, the waterproof structure may be destroyed, and the exchange of signals between the operation member side and the control case side may be hindered. May cause a reel failure. That is, in such a structure of Patent Document 1 in which the operation member is supported by the support shaft of the control case, it is difficult to ensure the strength while maintaining the waterproofness of the control case against an external force.

  In the structure of Patent Document 1, a fixing bolt is screwed into the support shaft to prevent the operation member attached to the support shaft of the control case from being removed. The form in which the fixing bolt is directly screwed into the case may adversely affect the waterproof structure and the electronic device, and it is necessary to separately provide a means for avoiding such an adverse effect, which is not desirable. .

  Furthermore, in the structure of Patent Document 1, two magnets are provided as detectors on the operation member, and these magnets are arranged in a separate detector accommodating portion of the operation member so as to face each other in the radial direction. It is difficult to reduce the diameter of the operating member that holds these magnets (thus reducing the size of the reel).

  In the structure of Patent Document 1, since the support shaft (the phase detection unit that detects the rotational phase of the operation member supported by the support shaft) and the control case are integrated, the reel size and design are changed. In addition, when the size or shape of the operation member to be supported by the support shaft of the control case is changed, a molding die for the control case or the like is newly required, and there is a concern that the cost may increase due to the design change.

  The present invention has been made paying attention to the above-described problem, and is waterproof in a case that accommodates a detection means for detecting the operation amount of the operation member while rotatably supporting the operation member for adjusting the drive motor output. An object of the present invention is to provide an electric fishing reel capable of preventing adverse effects due to external forces on the structure and the electronic device, and by reducing the diameter of the operating member, thereby reducing the increase in cost associated with the design change.

In order to achieve the above object, the present invention provides a spool that is provided between left and right side plates of a reel body and on which a fishing line is wound, a drive motor that is provided on the reel body and that rotationally drives the spool, An electric reel for fishing that is pivotally supported in the front-rear direction of the reel body and has an operation member that adjusts the output of the drive motor. The operation member detects an operation amount of the operation member. while being rotatably supported by a separate supporting member to the position has been waterproof case between the waterproof case having a detection means, wherein the position at a clearance from the waterproof case, the detection means is a magnetic sensor One magnet detected by the magnetic sensor is fixed to the axial end of the operating member, and the axial length direction of the magnet is substantially perpendicular to the axial direction of the operating member. Characterized in that it is arranged on the end face of the operating member.

  According to the electric fishing reel having the above-described configuration, the operation member is rotated by the support member that is separate from the waterproof case that is positioned between the waterproof case and the waterproof case that has a detection unit that detects the operation amount of the operation member. Since it is supported so as to be movable and is located with a gap from the waterproof case, that is, because the operation member is not supported by the case as in Patent Document 1 described above, the waterproof structure for accommodating the detection means It is possible to prevent the waterproof case from being exposed to an external force including an operating force of the operating member or an impact acting on the reel. Therefore, inconveniences such as the destruction of the waterproof structure and the occurrence of a failure in signal exchange between the operation member side and the waterproof case side can be avoided. In other words, according to the above configuration, the operation structure for adjusting the output of the drive motor is rotatably supported, and the adverse effect due to the external structure exerted on the waterproof structure of the case that houses the detection means for detecting the operation amount of the operation member and the electronic device is adversely affected. (The strength can be secured while keeping the waterproof case waterproof against external force).

In the above configuration, the detection means is a magnetic sensor, since the magnet is detected by the magnetic sensor in the axial end portion of the operating member is provided only one, as compared with the case where the magnet 2 or more operations The diameter of the member can be reduced. In this case, the magnet is arranged on the end surface of the operation member so that the axial length direction thereof is substantially perpendicular to the axial direction of the operation member . Such an orthogonal groove arrangement of the magnet is particularly useful when the operation member has a small diameter and it is difficult to process the magnet accommodating portion (particularly the axial hole extending in the axial direction of the operation member) into the operation member. is there.

  In the above configuration, it is preferable that the waterproof case is separate from the control case that houses the control unit that controls the drive motor, and is connected to the control case via electric wiring. By separating the waterproof case and control case in this way, a mold for molding the control case is newly prepared even when the reel size or design is changed or the size or shape of the operation member is changed. (For example, it is only necessary to change the length of the electrical wiring), and an increase in cost due to the design change can be suppressed.

  ADVANTAGE OF THE INVENTION According to this invention, the operation member for drive motor output adjustment is supported rotatably, and the adverse effect by the external structure with respect to the waterproof structure of a case which accommodates the detection means which detects the operation amount of an operation member, and an electronic device can be prevented. As a result, the fishing reel can be obtained by reducing the diameter of the operation member and reducing the increase in cost associated with the design change.

In addition, although the control part of this embodiment is comprised by arrange | positioning a control board and a circuit board to an up-down direction, for example, you may comprise these with one board | substrate.

  A line length measuring device (not shown) capable of detecting the amount of the fishing line wound around the spool 7 is disposed on the frame 3a or the frame 3b. When the spool 7 is rotationally driven by feeding / rewinding the fishing line, for example, the actual rotation amount and the rotation direction are detected by a magnet mounted on the rotating portion and a magnetic sensor for detecting the magnet, and the detection signal is obtained. Generated, calculated by the control unit, and displayed on the display unit 120.

  Also, a known clutch mechanism that moves the pinion 20 in the axial direction to switch the spool 7 between the fishing line winding state and the free rotation state is disposed in the reel body 5. The clutch mechanism has a function of interposing / disconnecting power transmission from the manual handle 6 and the drive motor 8 by being interposed in the power transmission mechanism 10, and is installed on the right side plate 5B side in this embodiment. A clutch plate (not shown) constituting the clutch mechanism includes a clutch OFF switching member 32 that switches power transmission from an ON state to an OFF state, and a clutch ON switching member 33 that switches power transmission from an OFF state to an ON state.

The clutch OFF switching member 32 is distributed and held between the clutch ON position and the clutch OFF position by a distribution holding spring (not shown) that engages with the clutch plate.

  The reel body 5 is provided with a power feeding unit 38 for supplying power to the drive motor 8. The power supply unit 38 is formed in a lower surface region on the front side of the left side plate 5A. A removable portable battery (not shown) is attached to the power supply unit 38 or placed on the feet. A power supply cord supplied with power from a battery or a power supply unit installed on a fishing boat is attached.

  An operation member 40 that adjusts the output of the drive motor 8 is disposed at the rear portion of the control case 102. The operation member 40 of the present embodiment has pivot shafts 41A and 41B pivotally supported so as to be pivotable in the front-rear direction between the left and right side plates 5A and 5B, and extends along the rear end edge 102a of the control case 102. Yes. The support shafts 41A and 41B have a solid metal structure and are arranged substantially in parallel with the spool shaft 7a. As a result, the operation member 40 is also exposed on the spool 7 side, and the front-rear direction In addition to (plan view shown in FIG. 1), it is configured so that it can be rotated in the vertical direction. In addition, about the operation member 40, the structure which forms the recessed part toward the front in the rear-end edge 102a of the control case 102, and supports it rotatably with respect to a control case may be sufficient. In addition, even if the axial length dimension of an operation member is long, sufficient intensity | strength can be ensured by forming the support shafts 41A and 41B of the operation member 40 as a metal solid body like this embodiment. .

  The operation member 40 is supported between the left and right side plates 5A and 5B, and has a planar operation portion 42 in the central region thereof and at least one side portion of the planar operation portion 42 (in the present embodiment, both side portions). And a stepped portion 43 to which the finger abuts when the finger (thumb) is placed on the operation unit 42.

  The operation unit 42 is formed in a plate shape and has a flat surface, and has a size that allows the abdomen of the thumb to be placed thereon. In this case, the operation unit 42 may be configured simply as a flat surface, but it is preferable to form a recess on the surface so that the sitting is stable when a finger is placed. Further, the stepped portion 43 only needs to regulate movement of the finger in the axial direction when the finger is placed on the operation portion 42. In this embodiment, the stepped portion 43 is provided on both sides of the operation portion 42. It is configured by integrally forming a substantially cylindrical member 45 that generates a step that becomes higher with respect to the surface.

  The substantially cylindrical member 45 formed on both sides of the operation unit 42 can be rolled in the front-rear direction with a thumb applied to the surface thereof, and functions as a dial-shaped operation unit that can be rotated. It has. Moreover, in such a structure, it is preferable to form unevenness etc. which continue over the circumferential direction on the surface of the dial-shaped operation part 45, and thereby, it is possible to perform the rotation operation without sliding the applied finger. Can be performed easily and stably.

  As shown in FIG. 2, particularly as clearly shown in FIGS. 3 and 4, the axial direction of one support shaft 41 </ b> A of the operation member 40 (in this embodiment, the support shaft 41 located on the handle 6 side). The end portion is positioned to face a waterproof case 80 having a waterproof structure fixed to the reel body 5 side. The waterproof case 80 includes a detection unit 84 that detects an operation amount of the operation member 40. In particular, in the present embodiment, the detection means 84 is a linear Hall IC mounted in a flat form on the substrate 82 in the waterproof case 80, and this linear Hall IC includes a Hall element, an amplifier, and a signal processing. The magnetic sensor is formed by packaging a circuit on a substrate 82 and outputs a voltage proportional to the magnitude of the magnetic flux density. Further, the waterproof case 80 that accommodates such a linear Hall IC forms a separate body from the control case 102 described above and is connected to the control case 102 via the electric wiring 70 (more precisely, the waterproof case 80 The substrate 82 of the case 80 is electrically connected to the substrate of the control case 102 via the electric wiring 70).

  One support shaft 41A of the operation member 40 positioned to face the waterproof case 80 is rotated by a support member 60 preferably having a bearing separate from the waterproof case 80 positioned between the waterproof case 80 and the waterproof case 80. Supported as possible. Note that the axial end portion of the other support shaft 41 </ b> B of the operation member 40 is also supported by the similar support member 60.

  Further, the support shaft 41 </ b> A of the operation member 40 supported in this manner has its end surface 41 a positioned at a predetermined gap C from the waterproof case 80. Here, the gap C is preferably 0.1 mm to 0.5 mm. If the size of the gap C is too large, the detection accuracy by the detection means 84 (in this embodiment, a linear Hall IC) is lowered, which is not desirable. The support member 60 is positioned on the basis of, for example, an annular positioning protrusion 80a formed on the surface of the waterproof case 80 facing the support member 60, and is fixed to the reel body 5 side adjacent to the waterproof case 80. Is done.

  The support member 60 that rotatably supports the support shaft 41A of the operation member 40 is preferably a main body 66 having a bearing, a receiving portion 67 that receives the waterproof case 80, and a reel main body 5 side that is located on both sides of the main body 66. And a pair of flange-shaped fixing portions 62 and 64 fixed to each other. The support member 60 having such a structure is fixed inside the support hole 66a of the main body 66 in a state where the support member 60 is fixed to the reel main body 5 side using screws 69 passed through the fixing holes 62a and 64a of the fixing portions 62 and 64. Thus, the support shaft 41A of the operation member 40 is rotatably received and supported. At this time, an O-ring 90 for sealing is inserted between the inner peripheral surface of the support hole 66a and the outer peripheral surface of the support shaft 41A.

  Further, in order to detect the operation amount of the operation member 40, when the detection unit 84 is a magnetic sensor as in the present embodiment, one support shaft 41 </ b> A of the operation member 40 positioned to face the waterproof case 80. A magnet 75 is provided as a detector. In particular, in the present embodiment, one magnet 75 detected by a magnetic sensor (linear Hall IC) is fixed to the axial end of the support shaft 41A of the operation member 40 with an adhesive or the like. It is arranged in a groove 59 (a recessed groove extending perpendicularly to the axial direction of the support shaft 41A) of the end surface 41a of the support shaft 41A so that the longitudinal direction is substantially perpendicular to the axial direction of the operation member 40. In this case, the magnet 75 has substantially the same length as the outer diameter of the support shaft 41A. As shown in FIG. 4, the N pole is magnetized at one end in the axial direction, and the axial length An S pole is magnetized at the other end in the direction. The detection means 84 composed of the linear Hall IC described above detects the operation amount (rotation phase) of the operation member 40 by detecting a change in the magnetic flux density of the magnet 75 accompanying the rotation operation of the operation member 40.

  As described above, according to the electric fishing reel 1 of the present embodiment, the axial end portion of the operation member 40 is between the waterproof case 80 having the detection means 84 that detects the operation amount of the operation member 40. The waterproof case 80 is supported by a support member 60 that is separate from the waterproof case 80, and is positioned with a predetermined gap C from the waterproof case 80, that is, as in Patent Document 1 described above. Since the operation member 40 is not supported by the case 80, the waterproof case 80 having a waterproof structure that houses the detection means 84 can be prevented from being exposed to an external force including an operation force of the operation member 40 and an impact acting on the reel. . Therefore, it is possible to avoid the inconvenience that the waterproof structure of the waterproof case 80 is destroyed, or that an obstacle occurs in the exchange of signals between the operation member 40 side and the waterproof case 80 side. That is, according to the configuration of the present embodiment, the waterproof structure of the waterproof case 80 that houses the detection means 84 that detects the operation amount of the operation member 40 while rotatably supporting the operation member 40 for adjusting the drive motor output. In addition, it is possible to prevent an adverse effect due to external force on the electronic device (strength can be ensured while keeping waterproofness of the waterproof case 80 against external force).

  In the configuration of this embodiment, the operation member 40 may be separated from the waterproof case 80 by cantilever support, but both ends of the operation member 40 can be rotated between the left and right side plates 5A and 5B of the reel body 5. By adopting a structure that supports the shaft, there is no need to screw a fixing bolt into the case in order to prevent the operation member from coming off as in Patent Document 1 described above. Therefore, there is no possibility of adversely affecting the waterproof structure of the waterproof case 80 and the electronic device, and it is not necessary to separately secure means for avoiding such adverse effects.

  In the configuration of the present embodiment, only one magnet 75 detected by the detection means 84 is provided at the axial end of the operation member 40. By doing so, the diameter of the operation member 40 can be reduced as compared with the case where two or more magnets are provided. In this case, the magnet 75 is disposed in the groove 59 of the end surface 41 a of the operation member 40 so that the axial direction of the magnet 75 is substantially perpendicular to the axial direction of the operation member 40. Such an orthogonal groove arrangement of the magnet 75 is particularly difficult to process the accommodating portion of the magnet 75 (for example, an axial hole extending in the axial direction of the operation member 40) into the operation member 40 because the operation member 40 has a small diameter. Useful in some cases. In addition, the effect of the diameter reduction and the orthogonal groove arrangement of the operation member 40 can be obtained by itself without the characteristic configuration of the present embodiment of “supporting the operation member 40 with the support member 60 and the gap C”. be able to.

  Further, in the configuration of the present embodiment, the waterproof case 80 is separated from the control case 102 that houses the control unit that controls the drive motor 8, and is connected to the control case 102 via the electrical wiring 70. Yes. When the waterproof case 80 and the control case 102 are separated from each other as described above, a mold for molding the control case 102 or the like even when the reel size or design is changed or the operation member 40 is changed in size or shape. (For example, it is only necessary to change the length of the electrical wiring 70), and an increase in cost due to the design change can be suppressed.

  As mentioned above, although embodiment of this invention has been described, this invention is not limited to embodiment mentioned above, In the range which does not deviate from the summary, it can implement variously. For example, in the above-described embodiment, the operation member 40 includes the planar lever-like operation unit 42 and the dial-like operation unit 45, but the operation member 40 may have any form. Further, the arrangement form and quantity of the magnets 75 provided on the operation member 40 are not limited to the form of the embodiment described above. For example, as shown in FIG. You may arrange | position in the hole 57 extended in the axial direction from the end surface 41a of 41 A of supporting shafts (operation member 40) so that the axial direction of the supporting shaft 41 may be followed. In this case, as shown in FIG. 5, the magnet 75 has an N pole magnetized on one side having a semicircular cross section and an S pole magnetized on the other side having a semicircular cross section. Further, two magnets 75 may be prepared, and the magnetic poles of these magnets 75 may be arranged so as to be opposite to each other by N and S (that is, the magnetic pole at the axial end of one magnet 75 and the end thereof) The magnetic poles at the axial ends of the other magnet 75 corresponding to the position of the portion may be different from each other).

  In the above-described embodiment, the detection means 84 is a magnetic sensor, and the operation member 40 is provided with the magnet 75 as a detector detected by the magnetic sensor. However, the detection means and the detection detected thereby. The child may be anything as long as the operation amount of the operation member 40 can be detected. For example, the detection unit 84 includes an angle sensor that generates a signal corresponding to the operation angle of the operation member 40, specifically, a potentiometer that outputs a change in resistance value corresponding to the operation amount of the operation member 40, It is possible to apply various structures such as an encoder provided with an encoder that generates a pulse corresponding to the operation amount of the operation member 40.
