Further, the magnet mounting portion 20d for mounting with the outer diameter of both the intermediate magnet 61 to be described later is formed between the left in Figure 2 of the small diameter portion 20 b and the large diameter portion 20a. For example, a magnet holding portion 27 made of a magnetic material obtained by electroless nickel plating on the surface of an iron material such as SUM (extrusion / cutting) is fixed to the magnet mounting portion 20d in a non-rotatable manner by, for example, serration coupling. The magnet holding part 27 is a quadrangular prism-shaped member having a square cross section and a through hole 27a through which the magnet mounting part 20d passes. The fixing method of the magnet holding part 27 is not limited to serration coupling, and various coupling methods such as key coupling and spline coupling can be used.

  A right end of the large-diameter portion 20a of the spool shaft 20 is disposed in a penetrating portion of the second side plate 9, and an engagement pin 29 constituting the clutch mechanism 21 is fixed thereto. The engagement pin 29 penetrates the large diameter portion 20a along the diameter, and both ends thereof protrude in the radial direction.

  As shown in FIG. 1, the clutch lever 17 is disposed behind the spool 12 at the rear portion between the pair of the first side plate 8 and the second side plate 9. The clutch lever 17 is connected to the clutch control mechanism 22 and slides up and down between the first side plate 8 and the second side plate 9 to switch the clutch mechanism 21 between a connected state and a disconnected state.

  The gear mechanism 19 includes a handle shaft 30, a main gear 31 fixed to the handle shaft 30, and a cylindrical pinion gear 32 that meshes with the main gear 31. The handle shaft 30 is rotatably mounted on the second side plate 9 and the second side cover 7, and rotation (reverse rotation) in the yarn feeding direction is prohibited by the roller-type one-way clutch 86 and the claw-type one-way clutch 87. Yes. The one-way clutch 86 is mounted between the second side cover 7 and the handle shaft 30.

  The casting control mechanism 24 includes a plurality of friction plates 51 disposed so as to sandwich both ends of the spool shaft 20 and a braking cap 52 for adjusting the clamping force of the spool shaft 20 by the friction plates 51. The left friction plate 51 is mounted in the bearing housing portion 14.

[Configuration of spool braking mechanism]
As shown in FIG. 5, the spool braking mechanism 25 includes a spool braking unit 40 provided on the spool 12 and the reel body 1, a rotational speed sensor 41 for detecting tension acting on the fishing line, and a spool braking unit 40. Has a spool control unit 42 for electrically controlling one of the four braking modes, and a mode knob 43 for selecting the four braking modes.

  The spool braking unit 40 is an electrically controllable unit that brakes the spool 12 by power generation. The spool braking unit 40 includes a rotor 60 including a plurality of (for example, four) magnets 61 arranged side by side in the rotation direction on the spool shaft 20, and a plurality of units connected in series so as to face the outer peripheral side of the rotor 60. (For example, four) coils 62 and a switch element 63 to which both ends of a plurality of coils 62 connected in series are connected. The spool braking unit 40 brakes the spool 12 by changing the duty ratio by turning on and off the current generated by the relative rotation of the magnet 61 and the coil 62 by the switch element 63. The braking force generated by the spool braking unit 40 becomes stronger as the ON time of the switch element 63 is longer (as the duty ratio is larger).

  The four magnets 61 of the rotor 60 are arranged side by side in the circumferential direction and have different polarities. The magnet 61 is a member having a length substantially equal to that of the magnet holding portion 27, the outer side surface is a surface having an arcuate cross section, and the inner side surface is a flat surface. The inner surface is disposed in contact with the outer peripheral surface of the magnet holding portion 27 of the spool shaft 20.

  As shown in FIG. 2, at the position facing the magnet 61 on the inner peripheral surface of the bobbin trunk 12b, for example, it is made of a magnetic material obtained by electroless nickel plating on the surface of an iron material such as SUM (extrusion / cutting). A sleeve 68 is attached. The sleeve 68 is fixed to the inner peripheral surface of the bobbin trunk 12b by appropriate fixing means such as press fitting or adhesion. When such a magnetic sleeve 68 is arranged so as to face the magnet 61, the magnetic flux from the magnet 61 concentrates and passes through the coil 62, thereby improving the power generation and braking efficiency.

The coil 62 is of a coreless type in order to prevent cogging and make the spool 12 rotate smoothly. Furthermore, no yoke is provided. The coil 62 is wound in a substantially rectangular shape so that the wound core wire faces the magnet 61 and is disposed in the magnetic field of the magnet 61. The four coils 62 are connected in series, and both ends thereof are connected to the switch element 63. The coil 62 is formed by being curved along the rotation direction of the spool 12 in a substantially concentric arc shape with respect to the spool axis so that the distance from the outer surface of the magnet 61 is substantially constant. For this reason, the clearance gap between the coil 62 and the rotating magnet 61 can be maintained constant. The coil 62 is attached to a circuit board 70 to be described later. The switch element 63 has , for example, two FETs ( field effect transistors) connected in parallel that can be turned on / off at high speed. Coil 62 connected in series to each drain terminal of the FET is connected. This switch element 63 is also mounted on the circuit board 70.

  The rotation speed sensor 41 uses, for example, a light projecting / receiving photoelectric switch having a light projecting unit and a light receiving unit. On the outer surface of the flange portion 12a of the spool 12 facing the circuit board 70, a detection cylinder portion 12c having a plurality of slits arranged at intervals in the rotation direction is integrally formed. The light projecting part and the light receiving part are arranged to face each other with the detection cylinder part 12c interposed therebetween, and the rotational speed of the spool 12 is detected by the light passing through the slit.

  The mode knob 43 is provided for selecting one of four braking modes. The four braking modes are braking modes in which the first braking force and the second braking force are different. The L mode (long throw mode), the M mode (medium distance mode), the A mode (all round mode), and W There are four modes (window mode).

  Here, the L mode is a long distance mode for using a fishing line having a low specific gravity and throwing a heavy lure having a low air resistance such as a spoon, a metal jig, and a vibration under conditions of good tailwind. It is a braking mode that takes into account the energy immediately after casting to the maximum, raises the maximum number of revolutions as much as possible, and further increases the flight distance by making most of the middle and later free, and the first braking force is set to the smallest ing.

  The M mode is a braking mode that is set so that a long throw can be comfortably performed with a device (plug) having a low air resistance, such as a center-of-gravity plug, pencil bait, and vibration. While suppressing overrun immediately after casting, it has been set so that it can extend the distance without causing backlash at the last minute by correcting well after the middle stage. When using a polyamide resin fishing line having a small specific gravity, it is preferable to set this mode as a reference.

  The A mode is a brake setting that uses the energy immediately after casting as much as possible and emphasizes the latter half of the growth. It can be used for almighty in most situations, regardless of the type of fishing line, mechanism, or wind direction. In particular, when a fluorocarbon fishing line having a high specific gravity is used, it is preferable to set this mode as a reference.

  The W mode is a mode in which the flight distance is increased by suppressing backlash as much as possible even in a situation where the flight distance of the device falls in a complete headwind, and the second braking force is set to be the largest. It is set for optimal use when throwing a fixed center of gravity minnow or flat-side crank toward the wind that is easy to rotate and slow down during flight. Also, even light casting such as pitching and skipping is set to prevent backlash firmly from low rotation.

  As shown in FIG. 4, the mode knob 43 is provided on the first side cover 6 so as to be rotatable and to be positioned at four rotational phases according to the braking mode. The mode knob 43 is provided with a magnet (not shown). As shown in FIG. 10, the circuit board 70 is provided with a mode knob position sensor 45 composed of two Hall elements arranged at an interval in a region where the magnet rotates. The mode knob position sensor 45 changes the ON / OFF of the two Hall elements due to the passage of the magnet, specifically, both on, one on the other off, one off the other on, both off, The rotational phase of the knob is detected, and one of the four braking modes is set according to the rotational phase.

  As shown in FIGS. 4 and 11, the mode knob 43 includes a knob portion 43a that is a dial for rotating to select four braking modes, and a knob on which the knob portion 43a is rotatably supported. A main body 43b, a magnet mounting base 43c for attaching a magnet (not shown) fixed to the tip of the knob portion 43a, and a magnet attachment formed on the back side of the knob main body 43b and swinging in conjunction with the rotation of the knob portion 43a. In order to restrict the swing of the base 43c, a wall 43d, which is a step that the side end of the magnet mounting base 43c hits, and a disc-like shape having four recesses disposed on the opposite side of the knob 43a of the knob main body 43b. It has a sounding disc 43e, and a sounding member 43f composed of a pin member and a spring member that abuts on a recess of the sounding disc 43e and produces sound. Here, the wall 43d that restricts the swinging of the magnet mount 43c is provided in the knob main body 43b. Therefore, when a wall is provided at the tip of the knob 43a as in the prior art and a sounding mechanism is incorporated in this part. It is possible to suppress the rattling that occurs.

  The spool control unit 42 includes a circuit board 70 mounted on a surface of the support member 81 facing the flange portion 12 a of the spool 12, and a control unit 55 mounted on the circuit board 70.

  The circuit board 70 is a washer-shaped ring-shaped board whose center is opened in a circular shape, and is arranged substantially concentrically with the spool shaft 20 on the outer peripheral side of the bearing housing portion 14. The circuit board 70 is attached to the support member 81 so as to be relatively rotatable. The circuit board 70 is positioned so as to be arranged at a predetermined phase with respect to the opening 8a. Thereby, even if the support member 81 is rotated with respect to the annular member 13 fixed to the opening 8a and attached / detached, the circuit board 70 is arranged in a constant phase.

  Here, since the circuit board 70 is mounted on the surface of the support member 81 facing the flange portion 12a of the spool 12, the coil 62 disposed around the rotor 60 can be directly attached to the circuit board 70. For this reason, the lead wire which connects the coil 62 and the circuit board 70 becomes unnecessary, and the insulation defect of the coil 62 and the circuit board 70 can be reduced. In addition, since the coil 62 is attached to the circuit board 70 attached to the support member 81, the coil 62 is attached to the support member 81 simply by attaching the circuit board 70 to the support member 81. For this reason, the spool braking mechanism 25 can be easily assembled. Furthermore, since the circuit board 70 is mounted on the spool shaft portion so as to be relatively rotatable and is positioned at a predetermined phase with respect to the opening 8a, the phase between the circuit board 70 and the reel body 1 does not change. For this reason, even if a magnet is provided on the mode knob 43 attached to the first side cover 6 that opens and closes and a Hall element is provided on the circuit board 70, the Hall element can always detect the magnet in the same positional relationship.

The control unit 55 is constituted by a microcomputer on which, for example, a CPU 55a, a RAM 55b, a ROM 55c, an I / O interface 55d, and the like are mounted. The ROM 55c of the control unit 55 stores a control program and stores data such as basic braking force, corrected braking force, and timer over two braking processes according to four control modes. In addition, set values such as a reference tension and a starting tension for each control mode are also stored. A rotation speed sensor 41 and a mode knob position sensor 45 for detecting the rotation position of the mode knob 43 are connected to the control unit 55. Further, the gate of each FET of the switch element 63 is connected to the control unit 55. The control unit 55 performs on / off control of the switch element 63 of the spool braking unit 40 by, for example, a PWM (pulse width modulation) signal having a cycle of 1/1000 second, based on the input from the sensors 41 and 45 and the control program. Specifically, the control unit 55 performs on / off control of the switch element 63 with a duty ratio D that decreases in accordance with the rotation speed in the selected braking mode. The control unit 55 is supplied with power from the power storage element 57 as a power source. This electric power is also supplied to the rotation speed sensor 41 and the knob position detection sensor 45 .

  The power storage element 57 as a power source uses, for example, an electrolytic capacitor and is connected to the rectifier circuit 58. The rectifier circuit 58 is connected to the switch element 63, has a rotor 60 and a coil 62, converts an alternating current from the spool braking unit 40 that functions as a generator into a direct current, stabilizes the voltage, and stores the power element 57. To supply.

  The rectifier circuit 58 and the power storage element 57 are also mounted on the circuit board 70. Each part including the coil 62 mounted on the circuit board 70 is covered with an insulating coating 90 made of a synthetic resin insulator formed by a hot melt molding method. The insulating coating 90 is formed in a cylindrical shape with a hook, and covers the coil 62, the circuit board 70, and the electrical components mounted on the circuit board 70. However, the light projecting / receiving portion of the rotation speed sensor 41 is exposed from the insulating coating 90.

  The components of the dual-bearing reel necessary for detachably attaching the spool braking mechanism 25 to the reel body 1 will be described.

  As shown in FIGS. 3, 4, and 6, the dual-bearing reel to which the spool braking mechanism 25 is attached is a cylindrical portion that is attached to the inner peripheral portion of the annular member 13 that is fixed to the opening 8 a of the first side plate 8. 81a and a support member 81 having a rotation support portion 81b provided inside the cylindrical portion 81a and supporting the end of the spool shaft 20, and a circuit board 70 and a circuit mounted on the inside of the cylindrical portion 81a so as to be relatively rotatable. The substrate assembly 80 in which the electrical component mounted on the substrate 70, the coil 62, the insert member 84, and the insulating coating 90 are integrated into a unit, and between the inside of the cylindrical portion 81a and the outside of the substrate assembly 80. Is attached to the inner peripheral portion of the opening 8a of the first side plate 8 so as not to rotate relative to the inner peripheral portion. Female thread 13a and An annular member 13 which is one of the components of the reel body 1 formed with the rotation stopper recess 13b, and a rotation stopper projection 82c that engages with the rotation stopper recess 13b is provided. It further includes a substrate fixing plate 82 which is a detent member for stopping. Although not shown, a sheet member for concealing the printing surface of the substrate assembly 80 is attached to the surface of the substrate assembly 80 that faces the support member 81.

  As shown in FIGS. 3, 4, and 6, the support member 81 includes a cylindrical portion 81 a that is attached to the inner peripheral portion of the annular member 13 that is fixed to the opening 8 a of the first side plate 8, and the cylindrical portion 81 a. And a rotation support portion 81 b that supports the end of the spool shaft 20. A groove portion 81d formed in an annular shape along the circumferential direction is formed in the inner peripheral portion of the cylindrical portion 81a, and a retaining member 83 made of a C-ring attached to the outer periphery of the substrate assembly 80 is provided in the groove portion 81d. It is mounted in a state where it is pressed against. Here, since the retaining member 83 made of a C-ring is mounted in a state of being pressed against the outer peripheral portion of the substrate assembly 80 and the groove portion 81d, the substrate assembly 80 moves in the axial direction from the support member 81. In addition to being regulated, the substrate assembly 80 is in a state of being rotatable relative to the support member 81. Further, as shown in FIGS. 4 and 6, a male screw portion 81 c is formed on the outer peripheral portion of the cylindrical portion 81 a, and the male screw portion 81 c is formed on the inner peripheral portion of the annular member 13. The support member 81 can be fixed to the annular member 13 by being screwed to 13a (see FIGS. 4, 6 and 9). Since the annular member 13 is fixed to the inner peripheral portion of the opening 8a of the first side plate 8 by three bolts (not shown) so as not to rotate relative to each other, the support member 81 therefore has an inner periphery of the opening 8a of the first side plate 8. It is fixed to the side so that it cannot rotate relatively.
