DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel, and more particularly, to a fishing reel in which a rotation speed detecting means of a spool is improved.

[0002]

2. Description of the Related Art In recent years, many fishing reels have been equipped with a spool or a spool as disclosed in Japanese Patent Publication No. 63-3568 or Japanese Utility Model Publication No. 3-10859. A line length measuring device that detects the number of rotations of the rotating body that rotates in conjunction with the number of rotations detecting means and measures the length of the payout line of the fishing line based on the detected value is mounted.

[0003] Based on the values measured by the line length measuring device, in the case of an electric fishing reel, a clutch is actuated by an actuator such as a motor or a solenoid so that the fishing line is fed out at a predetermined shelf position. In consideration of the shelf stop device that automatically stops the fishing line and the protection of the rod tip accompanying the winding of the fishing line, the spool drive motor is automatically stopped at the point where the fishing line is 2. Description of the Related Art There is known a boat equipped with a boat stop device for stopping winding.

[0004] In addition, even in a manual fishing reel, an alarm sound is generated when the fishing line reaches a predetermined feeding amount or winding amount based on a measurement value of a line length measuring device. It has been known. Conventionally, magnetic sensors such as reed switches and Hall elements have been widely used as rotation number detecting means for detecting the rotation number of the spool. However, the Hall element rotates the spool from a low rotation range to a high rotation range. The number of rotations can be detected, whereas the rotation range in which the reed switch can detect is within about 8000 rpm.

[0005] Therefore, from such a difference in performance,
For example, in the case of a boat fishing reel that feeds a device to a predetermined shelf position in the sea, the rotational speed of the spool is relatively slow (usually 2000 to 3000 rpm, and at the earliest 6000 rpm), so magnetic attraction is used. In the case of a reel that uses a reed switch and throws a tackle to a predetermined point by a casting operation, the rotation speed of the spool at the time of feeding the fishing line is high (for example, 20,000 rpm for a lure). Hall elements for detecting the number of rotations are widely used.

[0006]

However, due to a change in the situation of the fishing spot (a sudden withdrawal of a fishing line due to a fish hit, a change in the fishing method, etc.), even in a fishing reel, the spool rotation speed at the time of feeding the fishing line is reduced. Is sometimes high speed, and in this case, the rotation speed cannot be detected by the reed switch, so that the yarn length measurement device cannot reliably measure the yarn length.

When the number of rotations of the spool is detected by using the Hall element, the spool element is suitable for high-speed rotation detection in terms of performance. However, the Hall element consumes a large amount of power. The life of the built-in battery power supply has been significantly shortened, and the batteries have to be replaced frequently, which is troublesome and uneconomical. The present invention has been devised in view of such circumstances, and can reliably detect the number of rotations of a spool from a low rotation range to a high rotation range.
It is an object of the present invention to provide a fishing reel provided with a spool rotation number detecting means that consumes less power of a battery power supply built in the reel.

[0008]

According to a first aspect of the present invention, there is provided a fishing reel including a rotation speed detecting means for detecting a rotation speed of a spool rotatably supported by a reel body. In the fishing reel described above, the rotation number detecting means comprises a spool or a magnet mounted on a rotating body which rotates in conjunction with the spool, and a reed switch mounted on the reel body facing the magnet. A first detecting means, the magnet, and a second detecting means comprising a Hall element mounted on the reel body opposed thereto, and when the rotation speed of the spool exceeds a predetermined value, the Hall element The power supply to the second detection means is started to make the second detection means operable.

The invention according to claim 2 is the invention according to claim 1.
4. The fishing reel according to claim 3, wherein an impact sensor is mounted on the reel body, and power is supplied to the Hall element based on a detection signal of the impact sensor during casting. According to the invention, in the fishing reel according to the first aspect, when the value detected by the first detecting means exceeds a predetermined value, power supply to the hall element is started.

According to the first aspect of the present invention, the first detecting means detects the number of rotations of the spool when the fishing line is fed, but when the number of rotations of the spool exceeds a predetermined value, the first element detects the rotation of the spool. Is started, and the second detecting means operates. And in the invention according to claim 2,
The power supply to the Hall element is started based on the detection signal of the impact sensor during the casting operation. In the invention according to claim 3, when the detection value by the first detection means exceeds a predetermined value, the power supply to the Hall element is stopped. Once started, the second detecting means operates.

FIG. 4 shows the control mechanism of this embodiment housed in the control box 25. In the figure, reference numeral 49 denotes a microcomputer which performs a thread length calculation, a thread length display, and data writing control. Is a CPU (central processing unit) 51 which controls and manages a program memory, a data memory, a timer, and an input / output device, and executes an arithmetic operation and a transfer process necessary for processing a given job; ROM 53 for storing the yarn length calculation formula and the like
And R for storing data such as the calculation result of the CPU 51.
An AM 55, an input interface (INTI) 57 and an output interface (INTO) 59 are provided, and these are connected to the CPU 51 via a bus 61.

In FIG. 4, reference numeral 63 denotes first detecting means for detecting the number of rotations and the direction of rotation of the spool 1. The first detecting means 63 is opposed to a pair of reed switches 63a and 63b as shown in FIGS. And a plurality of magnets 65 fixed to the inner peripheral edge of the spool 1. Then, a forward / reverse rotation determination signal of the spool 1 obtained by turning on / off the reed switches 63a, 63b by the magnet 65 at any point is taken into the CPU 51 via the input interface 57, thereby providing built-in up / down. The down counter is set to an up-count or down-count state.

Then, the rotation pulse of the spool 1 obtained by turning on / off the reed switches 63a and 63b is input to the up / down counter through the input interface 57, so that the up / down counter is counted up or down. It has become. Further, the input interface 57 includes:
The ultrasonic sensor 45 is connected via the receiving circuit 67,
The ultrasonic sensor 43 and the display 33 are connected to the output interface 59 via a transmission circuit 69.

Then, similarly to the yarn length measuring device disclosed in Japanese Patent Application Laid-Open No. 4-276510, the time difference Δt until the reflected wave of the ultrasonic wave emitted from the ultrasonic sensor 43 is received by the ultrasonic sensor 45 is defined as A timer 71 incorporated in the computer 49 measures and based on this time difference Δt, the CPU 51 firstly turns the winding surface 47 and both ultrasonic sensors 43 and 4.
Is calculated by the following formula: distance d = sonic speed 331 (m / sec) × 1/2 × Δt stored in the ROM 53, and the fishing line 1 wound around the spool 1 is calculated.
The thread diameter D of No. 9 is calculated by the following equation: thread diameter D = (cd) × 2. In this equation, c is the distance between the ultrasonic sensors 43 and 45 and the axis of the spool shaft 3, as shown in FIG.

Then, based on the number of revolutions N of the spool 1 measured by the first detecting means 63 and the thread winding diameter D, the ROM 53
Is calculated from the calculation formula of the yarn length L = π · D · N stored in the memory 33, and the calculation result is displayed on the display 33 via the output interface 59.

By the way, as described above, the rotation range in which the reed switches 63a and 63b for detecting the number of rotations of the spool can detect is within about 8000 rpm, and the boat fishing for feeding the device to a predetermined shelf position in the sea. In this case, since the rotation speed of the spool 1 is usually relatively low, such as 2000 to 3000 rpm, the rotation speed of the spool 1 can be detected by the reed switches 63a and 63b.

However, when the double-bearing type reel 27 is cast and the mechanism is fed out, the rotation speed of the spool 1 becomes 1000 even when fishing on a ship with the lowest rotation speed.
0 rpm, and in this case, the reed switches 63a, 63
3b becomes impossible, and the yarn length measuring device cannot reliably measure the yarn length. Therefore, in the present embodiment, in addition to the same configuration as the conventional one as described above, FIG.
As shown in FIG. 2, a pair of Hall elements 73a, 73b (only one Hall element 73a is shown in FIGS. 1 and 2) is opposed to the magnet 65 via a bracket 75 and a reel frame. 29 and the second detecting means 73 by the Hall elements 73a and 73b and the magnet 65.
In addition, an impact sensor 77 for detecting a caster's casting operation is mounted on the bracket 75, and based on a detection signal of the impact sensor 77 during casting, power supply to the hall elements 73a and 73b is started and The second detection means 73 is operable.

The impact sensor 77 is composed of, for example, a reed switch, a magnet and a spring, and a conventionally known sensor in which a magnet is moved by acceleration due to a casting operation to operate a reed switch, or two piezoelectric ceramics are bonded. A conventionally well-known device is used in which one side of the formed bimorph element is fixed, and a voltage generated when the tip vibrates during a casting operation is detected.

The impact sensor 77 has a set bearing for rotating the spool 1 at a rotational speed exceeding a predetermined value (8000 rpm) at which the reed switches 63a and 63b cannot detect the rotational speed by a casting operation. When the signal acts on the reel 27, the signal is transmitted to the microcomputer 49.

On the other hand, as shown in FIG. 4, a current is supplied to the Hall elements 73a and 73b from a battery power supply 81 via a switch circuit 79 composed of switching elements such as FETs. 73a, 73
b, a magnetic field of the magnet 65 acts in a direction perpendicular to the direction of the current flowing through the hole element b. When this magnetic field acts on the Hall elements 73a and 73b for each rotation of the spool 1, the Hall effect is generated. The voltages of the elements 73a and 73b are applied to a pulse generation circuit 83 composed of an operational amplifier or the like.
Is output in proportion to the number of rotations. Then, this pulse signal is input to the input interface 5
The microcomputer 49 receives the data from the CPU 51 via the CPU 7 and uses the data as thread length measurement data.
When a signal is input to the switch circuit 79, the switch circuit 79 is turned on to start power supply to the hall elements 73a and 73b.

At this time, the reed switch 63
When the reed switches 63a and 63 detect the rotational speed of the spool 1 again, the microcomputer 49 turns off the switch circuit 79 when the rotational speed of the spool 1 decreases. Then, the power supply to the hall elements 73a and 73b is stopped.

In FIG. 1, reference numeral 85 denotes a level wind mechanism, and 87 denotes a power switch (ON / OFF switch) provided on the operation panel 31. Since the present embodiment is configured as described above, in fishing the boat, when the device is fed to a predetermined shelf position in the sea, the rotation speed of the spool 1 is relatively slow and the rotation by the reed switches 63a and 63b is performed. Since the number can be detected, at the time of the low rotation, the first detecting means 63 detects the rotation number N of the spool 1, and the detection value is measured and calculated by the ultrasonic sensors 43 and 45. The yarn length measurement is performed based on the yarn winding diameter D.

On the other hand, if the device is thrown at a predetermined point by the casting operation, the rotation speed of the spool 1 may be so high that detection by the reed switches 63a and 63b may not be possible. Is applied to the dual-bearing type reel 27, the impact sensor 77 detects this and the microcomputer 49
Send a signal to. And the microcomputer 49
When a signal from the shock sensor 77 is input, the switch circuit 79 is turned on to turn on the Hall elements 73a, 73b.
b, the power supply to the reed switches 63a, 63
The second detecting means 73 composed of the Hall elements 73a and 73b and the magnet 65 operates in place of 3b, and a signal output from the pulse generating circuit 83 and proportional to the rotation speed of the spool 1 is taken into the CPU 51 via the input interface 57. Then, it is used as the data of the yarn length measurement in the CPU 51.

Then, as described above, at this time, the reed switches 63a and 63b are in a measurement impossible state, but the rotational speed of the spool 1 is reduced, and the reed switches 63a and 63b are turned off.
When the motor 63 detects the rotational speed of the spool 1 again, the microcomputer 49 turns off the switch circuit 79 to stop the power supply to the Hall elements 73a and 73b.

As described above, in the present embodiment, the means for detecting the number of revolutions of the spool 1 is provided by the reed switches 63a and 63d.
b and the first detecting means 63 by the magnet 65, and the second detecting means 73 by the Hall elements 73a and 73b and the magnet 65. When the rotation speed of the spool 1 reaches a predetermined value, the Hall elements 73a and 73b And the rotation speed of the spool 1 is detected by energizing the rotation speed of the spool 1, so that the power consumption is extremely small as compared with the conventional rotation speed detection means that always energizes the Hall element and detects the rotation speed of the spool.
Compared with the conventional rotation speed detecting means for detecting the rotation speed of the spool using only the reed switch, the rotation speed of the spool 1 can be reliably detected from the low rotation speed range to the high rotation speed range.

Although not shown, the impact sensor 77
In addition to the above-described embodiment using the first embodiment, the reed switch 63 according to the first embodiment of the invention according to the first and third aspects of the present invention.
If the detection ranges of a and 63b are within about 8000 rpm, a predetermined spool rotation speed of, for example, 7000 rpm is recorded as a predetermined value in the ROM 53, and the spool rotation speed detected by the reed switches 63a and 63b is set to the predetermined value. Is reached, the microcomputer 49 turns on the switch circuit 79 to turn on the Hall element 73.
When the rotation speed of the spool 1 is reduced to a predetermined value or less, the microcomputer 49 turns off the switch circuit 79 to stop the power supply to the Hall elements 73a and 73b. May be configured.

Thus, according to the present embodiment as well, it is possible to achieve the intended purpose, similarly to the above embodiment.

As described above, according to the present invention, the power consumption is extremely small as compared with the conventional rotation speed detecting means for detecting the rotation speed of the spool by energizing the Hall element at all times. In addition, compared with the conventional rotation speed detecting means for detecting the rotation speed of the spool using only the reed switch,
It has become possible to reliably detect the rotation speed of the spool from the low rotation range to the high rotation range.
