[Structure of reel brake mechanism]

The reel brake mechanism 25, as shown in Fig. 5, has a reel brake unit 40 provided on the reel 12 and the reel body 1, and a rotational speed sensor 41 for detecting the tension acting on the fishing line. A reel control unit 42 that electronically controls the reel brake unit 40 in one of four brake modes, and a mode knob 43 for selecting four brake modes.

The spool brake unit 40 is electrically controllable in the case where the spool 12 is braked by power generation. The spool brake unit 40 includes a rotor 60 including a plurality of (for example, four) magnets 61 arranged in the rotation direction of the spool shaft 20, and a plurality of rotors 60 disposed in series with the outer peripheral side of the rotor 60. One (for example, four) coils 62 and a switching element 63 connected to both ends of a plurality of coils 62 connected in series. The spool brake unit 40 turns on/off the current generated by the relative rotation of the magnet 61 and the coil 62 by the switching element 63, and changes the duty ratio to brake the spool 12. The braking force generated by the spool brake unit 40 becomes stronger as the on-time of the switching element 63 is longer (the duty ratio is larger).

The four magnets 61 of the rotor 60 are arranged side by side in the outer circumferential direction to have different polarities. The magnet 61 has a member having the same length as the magnet holding portion 27, and its outer surface is a surface having an arcuate cross section, and the inner side surface is a flat surface. The inner side surface thereof 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, the inner peripheral surface of the winding body portion 12b is opposed to the magnet 61. For example, an electric field-free nickel plating treatment is applied to the surface of the iron material such as SUM (extrusion, cutting). The sleeve 68 of the magnetic system. The sleeve 68 is fixed to the inner circumferential surface of the winding body portion 12b by an appropriate fixing means such as press fitting or bonding. When the magnetic sleeve 68 is disposed to face the magnet 61, the magnetic flux from the magnet 61 concentrates and passes through the coil 62, thereby improving power generation and braking efficiency.

The coil 62 has a coreless structure in order to prevent the cogging effect from rotating the reel 12 more smoothly. And no yoke is provided. In the coil 62, the wound core wire is wound approximately rectangularly so as to face the magnet 61 and placed in the magnetic field of the magnet 61. The four coils 62 are connected in series, and both ends thereof are connected to the switching element 63. The coil 62 is disposed along the reel 12 with respect to the spool shaft in order to be substantially constant from the outer side surface of the magnet 61. The direction of rotation is curved to form an arc shape of the actual concentric shape. Therefore, the gap between the coil 62 and the rotating magnet 61 can be maintained constant. The coil 62 is attached to a circuit board 70 which will be described later.

As shown in FIG. 5, the switching element 63 has, for example, two FETs 63a (field effect transistors) which can be connected in parallel at high speed for on/off control. A coil 62 connected in series is connected to each drain terminal of the FET 63a. The switching element 63 is also mounted on the circuit board 70.

As the rotation speed sensor 41, for example, a light-emitting type photoelectric switch having a light-emitting portion and a light-receiving portion is used. The detection cylinder portion 12c is integrally formed on the outer surface of the flange portion 12a of the spool 12 facing the circuit board 70. The detection cylinder portion 12c has a plurality of slit portions arranged at intervals in the rotation direction, and the rotation speed is sensed. The light-emitting portion and the light-receiving portion are disposed to face each other across the detecting cylinder portion 12c, and the rotation speed of the spool 12 is detected by the light passing through the slit portion.

The mode knob 43, is set to select one of four brake modes. The four braking modes are braking modes with different first braking force and second braking force, and are L mode (long shot mode), M mode (medium distance mode), A mode (general mode), and W mode (strong wind mode). The four modes.

The L mode here is to use a fishing line with a small specific gravity. Under the condition of downwind, the air resistance of the spoon type bait, the metal hair hook bait, the trembling type bait, etc. is smaller and the heavier fishing group (the bait) is super Far-distance mode of far throwing. It is considered that the energy after the throwing is used to the limit, and the maximum number of revolutions is increased as much as possible. After the middle stage, the braking mode in which the flying distance is extended without the braking force is set to minimize the first braking force.

The M mode is a braking mode in which a fishing group (plug type bait) having a small air resistance such as a center-of-gravity type plug type bait, a pencil type bait, or a quake type bait can be smoothly performed. It is set to prevent excessive exit after the throwing, and can be technically corrected after the middle stage, and the flight distance is extended to the maximum limit without causing the fishing line to become entangled. When a fishing line of a polyamine resin having a small specific gravity is used, it is preferable to set the mode as a reference.

In the A mode, the braking force is set to: use the energy after the throwing to the limit, and focus on the distance extension in the latter half. Regardless of the type of fishing line or fishing group, and the direction of the wind, it can be used in most situations. In particular, when a fluorocarbon-based fishing line having a large specific gravity is used, it is preferable to set the mode as a reference.

The W mode is a mode in which the flight distance is extended as much as possible while the flight distance of the fishing group is reduced, and the second braking force is set to the maximum. It is set to be the most suitable for the case where the center of gravity fixed fish type bait that rotates in flight and is easily decelerated, or the flat side swing type bait is thrown toward the wind. Moreover, it is possible to surely prevent the occurrence of the fishing line entanglement from the low rotation even if it is a light throwing technique such as a pitching technique or a skiding technique.

The mode knob 43, as shown in Fig. 4, is disposed in the first side casing 6 so as to be freely rotatable and positionable in four rotational phases in response to the braking mode. A magnet (not shown) is provided in the mode dial 43. As shown in Fig. 10, the circuit board 70 is provided with a mode knob position sensor 45 composed of two Hall elements which are disposed in a region where the magnet rotates with a space therebetween. The mode knob position sensor 45 changes the on/off of the two Hall elements caused by the passage of the magnet, more specifically, the two are turned on, one of them is turned on, and the other is turned off. When the other side is turned off and both are turned off, the control unit 55, which will be described later, detects the rotational phase of the mode dial, and sets one of the four brake modes in accordance with the rotational phase.

The mode dial 43, as shown in FIGS. 4 and 11 is a dial having a dial for adjusting the four brake modes, that is, a knob portion 43a, and a knob body rotatably supporting the knob portion 43a. 43b, a magnet mounting table 43c to be attached to a distal end portion of the knob portion 43a for mounting a magnet (not shown), and a magnet mounting table formed on the back side of the knob main body 43b for swinging in conjunction with the rotation of the knob portion 43a The swing of 43c is restricted, and the stepped portion that is in contact with the side end portion of the magnet mounting base 43c is a disk portion 43d, and a disk-shaped sounding circle having four concave portions disposed on the opposite side of the knob portion 43a of the knob main body 43b. The plate 43e and the sounding member 43f constituted by the pin member and the spring member which are in contact with the concave portion of the sounding circular plate 43e. Since the knob main body 43b is provided with the wall portion 43d for restricting the swing of the magnet mounting table 43c, it is possible to prevent the wall portion from being provided at the front end portion of the knob portion 43a and the assembly of the sound generating mechanism when the portion is assembled as in the prior art. The structure of the swaying problem.

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

The circuit board 70 is a ring-shaped substrate having a washer shape that is circularly opened at the center, and is disposed on the outer peripheral side of the bearing housing portion 14 so as to be substantially concentric with the spool shaft 20 . The circuit board 70 is attached to the support member 81 so as to be relatively rotatable. The circuit board 70 is positioned to be disposed with a predetermined phase with respect to the opening 8a. Thereby, even if the support member 81 is rotated and attached to the annular member 13 fixed to the opening 8a, the circuit board 70 is placed in a specific phase.

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 mounted on the circuit board 70. Therefore, the wire for connecting the coil 62 to the circuit board 70 is not required, and the insulation failure of the coil 62 and the circuit board 70 can be reduced. Further, since the coil 62 is the circuit board 70 attached to the support member 81, the coil 62 is attached to the support member 81 as long as the circuit board 70 is attached to the support member 81. Therefore, the spool brake mechanism 25 can be easily assembled. Further, since the circuit board 70 is mounted so as to be rotatable with respect to the spool shaft portion and positioned at a predetermined phase with respect to the opening 8a, the phase of the circuit board 70 and the reel body 1 does not change. Therefore, even if the mode knob 43 attached to the opened and closed first side casing 6 is provided with a magnet and the Hall element is provided on the circuit board 70, the Hall element can detect the magnet in the same positional relationship at any time.

The control unit 55 is constituted by a microcomputer equipped with, for example, a CPU 55a, a RAM 55b, a ROM 55c, an I/O interface 55d, and the like. The control program is stored in the ROM 55c of the control unit 55, and data on the basic braking force, the auxiliary braking force, the timer, and the like for the two brake processes are stored in accordance with the four control modes. Further, the reference tension of the tension of each control mode, the set value of the starting tension, and the like are also stored. The control unit 55 is connected to a rotation speed sensor 41 and a mode knob position sensor 45 for detecting the rotational position of the mode dial 43. The gate of each FET 63a of the switching element 63 is connected to the control unit 55. The control unit 55 turns on/off the switching element 63 of the reel braking unit 40 by, for example, a PWM (Pulse Width Modulation) signal of a period of 1/1000 second by an input and a control program from each of the inductors 41 and 56. Open control. More specifically, the control unit 55 performs on/off control of the switching element 63 at the duty ratio D which is reduced in accordance with the rotation speed in the selected braking mode. The control unit 55 is supplied with electric power from the electric storage device 57 as a power source. This electric power is also supplied to the rotational speed sensor 41 and the knob position detecting sensor 56.

The storage element 57 as a power source is connected to the rectifier circuit 58 by using, for example, an electrolytic capacitor. The rectifier circuit 58 is connected to the switching element 63, and converts an alternating current from the spool braking unit 40 having the rotor 60 and the coil 62 as a generator function into a direct current and stabilizes the voltage, and supplies it to the storage element 57. .

The rectifier circuit 58 and the storage element 57 are also mounted on the circuit board 70. Each portion of the coil 62 included in the circuit board 70 is covered with an insulating resin film 90 made of a synthetic resin insulating layer formed by a hot melt molding method. The insulating film 90 is formed in a cylindrical shape having a flange, and covers the coil 62, the circuit board 70, and electrical components mounted on the circuit board. The light-emitting portion of the rotational speed sensor 41 is exposed from the insulating film 90.
