Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel provided with a line length measuring device for measuring and displaying a line length from the number of rotations of a spool.

[0002]

2. Description of the Related Art In recent years, in order to improve fishing results, many fishing reels have recently provided a line length, that is, a feeding amount and a winding amount of a fishing line, based on the number of rotations of a spool detected by a number of rotations detecting means. Is installed, and the angler can accurately set the hook on a predetermined shelf position based on the yarn length displayed on the display.

[0003] Conventionally, this kind of yarn length measuring device is
The microcomputer is controlled by a microcomputer in a control box provided on the reel body, and a battery power supply for driving the microcomputer, the display, and the like is built in the reel body. However, since this battery power supply has a small capacity, if current is constantly passed through a sensor with large power consumption such as a Hall element, there is a trouble that the battery life is shortened and the battery must be replaced frequently. In particular, in the case of a small fishing reel such as a casting reel, the battery power supply is further reduced in size and capacity, so that the battery life is further shortened.

Therefore, in order to suppress unnecessary power consumption,
A fishing reel in which power supply to a spool rotation detection sensor and switching means is stopped when a spool stop state is detected for a predetermined time is disclosed in Japanese Utility Model Publication No. 3-10859 and Japanese Patent Application Laid-Open No. 3-158702. In recent years, fishing reels having an automatic stop function for automatically stopping the line length measuring device itself by detecting a spool stop state for a predetermined time have become mainstream.

[0005]

However, in actual fishing, the spool does not rotate when waiting without touching the fishing reels. You may want to check if it is in a position. In such a case, it has been pointed out that if the yarn length measuring device is stopped and the display on the display is turned off, the position of the device cannot be quickly confirmed.

[0006] In addition to the conventional examples described in the above publications, this type of fishing reel has conventionally been measured at a water depth where the display on the display is not so carefully watched during the winding / unwinding operation of the fishing line. Since the length of the line is displayed on the display, there is a problem that power is constantly consumed and a power saving effect corresponding to actual fishing cannot be expected. The present invention has been devised in view of such circumstances, and it is an object of the present invention to provide a fishing reel capable of expecting an efficient power saving effect corresponding to actual fishing while maintaining the function of a line length measuring device. And

[0007]

According to a first aspect of the present invention, there is provided a fishing reel comprising: a spool rotatably supported by a reel body; and a rotation direction and a rotation number of the spool. Rotation number detection means, a yarn length measurement means for measuring the yarn length based on the detection result of the rotation number detection means, a display for displaying the yarn length measured by the yarn length measurement means, and the rotation number detection means Storage means for storing a detection result detected by the above, a measurement value of the line length measuring means, and a predetermined condition of a rotating operation state of the spool associated with the feeding or winding of the fishing line for interrupting power supply to the display; Detecting the rotational operation state of the spool from the detection result of the rotational speed detecting means and the measurement value of the yarn length measuring means, and when the rotational operation state corresponds to the predetermined condition, shuts off power supply to the display, and Turn on the display function of the display unit. Characterized by comprising a display stopping means for the F.

(Operation) According to the fishing reel of the first aspect, the display stopping means detects the rotation operation state of the spool from the detection result of the rotation speed detecting means and the measurement value of the line length measuring means. Then, when the rotation operation state satisfies the predetermined condition, the display stop means cuts off the power supply to the display and turns off the display function.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a fishing reel according to an embodiment of the present invention. In the drawing, reference numeral 1 denotes a frame of a reel body 3, and reference numerals 5 and 7 denote side plates attached to the left and right sides of the frame 1. To the spool 1 via the spool shaft 9
1 is rotatably supported.

The spool 11 is configured such that a fishing line is wound by driving the spool motor 13 or winding the handle 15. The spool motor 13 is provided in a motor case integrally formed with the frame 1 in front of the spool 11. It is stored in. Then, in front of the upper part of the side plate 7,
As with the electric reel disclosed in Japanese Patent Application Laid-Open No. 77978, a power lever 1 for adjusting the motor output of the spool motor 13 is used.
7 is attached so as to be rotatable in the same direction as the handle 15.
The control means (microcomputer) 21 of FIG. 2 mounted inside the motor 9 continuously increases and decreases the motor output from the motor stopped state to a maximum value (0 to 100%).
The rotation speed is controlled.

A clutch lever 23 of a clutch mechanism mounted in the side plate 7 is attached to the rear of the side plate 7.
With the operation of OFF, the spool motor 13 to the spool shaft 9 is
And the driving force of the handle 15 is transmitted and cut off. Thus, the control box 19 is mounted on the frame 1 on the upper part of the reel body 3, and a display 27 for displaying the yarn length is provided on an operation panel 25 on the surface thereof.

At the bottom of the control box 19, a transmitting ultrasonic sensor 29 and a receiving ultrasonic sensor 31 are arranged in a V-shape so as to face the spool 11, and the frame 1 is opposed to the frame 1. A pair of reed switches 33a are provided on one end side peripheral portion of the spool 11 as rotation number detecting means 33 for detecting the rotation number and the rotation direction of the spool 11.
And a plurality of magnets 33b.

As in the yarn length measuring device disclosed in Japanese Patent Application Laid-Open No. 4-276510,
The timer 35 measures a time difference t until the ultrasonic wave emitted from the ultrasonic sensor 29 to the spool surface of the spool 11 is received by the ultrasonic sensor 31, and based on the time difference t,
First, the distance a between the wound surface and the ultrasonic sensors 29, 31
Is calculated by the following formula: distance a = sonic velocity 331 (m / sec) × 1/2 × t (1) stored in the ROM, and the line diameter D of the fishing line wound around the spool 11 is calculated. Is calculated by the following formula: thread diameter D = (ba) × 2 (2) stored in the ROM.

In this equation, b is the distance between the ultrasonic sensors 29, 31 and the axis of the spool shaft 9. Then, based on the actual rotation speed N of the spool 11 measured by the rotation speed detecting means 33 and the yarn winding diameter D calculated by the above formula, the yarn length L = π · D · N: Calculate the thread length L from the formula (3), display the calculation result on the display 27 via the display drive circuit 37, and
Is configured to calculate the winding speed of the fishing line by calculating the winding amount of the fishing line per unit time based on the rotation pulse signal of the spool 11 taken in from the reed switch 33a and the timer 35.

The thread length display on the display 27 is reset by operating the reset switch 39 mounted on the operation panel 25. In addition to the reset switch 39 on the operation panel 25, A memo switch 41 and a boat switch 43 are mounted, and these are connected to the control means 21 as shown in FIG. And the display 27
While watching the display, the angler sets a gimmick, for example, 50m from the surface of the water.
When the shelf memo switch 41 is operated in the extended position, the CP
U stores the depth of water 50m in the RAM as the shelf position,
Display 27 reset by operation of reset switch 39
When the displayed value “0.0 m” is taken as the winding end and the boat switch 43 is operated, for example, at a water depth of 2 m before the winding end, C
The PU stores the depth of water 2 m in the RAM as the boat stop position. When the power lever 17 is operated, the motor output is continuously adjusted from the motor stopped state to the maximum value, and the fishing line is wound up.
Sends a motor stop command to the spool motor drive circuit 45 to stop the spool motor 13, and sends an operation command to the alarm drive circuit 47 to activate the alarm 49 provided on the operation panel 25. When the device reaches the berth stop position by the winding operation of
U activates an alarm 49 via an alarm drive circuit 47.

As in the prior art, a battery power source for driving the control means 21, the display 27, the timer 35 and the like is built in the reel body. Thus, the fishing reel 51 according to the present embodiment has the following features in addition to the configuration described above.

That is, as described above, conventionally, in this type of fishing reel, at the time of the winding / unwinding operation of the fishing line, the measured line length is displayed on the display even at the water depth where the display is hardly seen on the display. Due to the structure, electric power is always consumed, and it is not possible to expect a power saving effect corresponding to actual fishing. For example, as described above, when the boat stop position is 2 m and the shelf position is 50 m, the fisherman usually hardly sees the display while the gimmick is descending in the range of water depth of 10 m to 40 m, and the power When the mechanism is being wound at a high speed by operating the lever 21, the display on the display 21 changes so quickly that the angler can hardly read.

In this embodiment, when the fishing line is paid out, the line length L calculated by the above-mentioned equations (1) to (3) is: a: 10 m ≦ line length L ≦ shelf position−10 m During the winding of the fishing line, the line length L calculated by the formulas (1) to (3) is: b: the boat stop position +10 m ≦ the line length L ≦ the shelf position−10 m And the winding speed S of the fishing line calculated based on the rotation pulse signal of the reed switch 33a and the timer 35.
C: Winding speed S ≧ 1.9 m / sec. In the case of the above, the above-mentioned a to c are such that “the spool of the spool accompanying the feeding or winding of the fishing line is set so that the CPU cuts off the power supply from the battery power supply to the display 27 and turns off the display function of the display 27. It is stored in the ROM of the control means 21 as the "predetermined condition of the rotating operation state".

Then, the CPU determines the predetermined conditions a to c
From the rack position and the boat stop position stored by the angler in the RAM, it is monitored whether or not the rotational operation state of the spool 11 has reached the predetermined conditions a to c at the time of winding / unwinding the fishing line.
When the rotational operation state of the spool 11 satisfies the predetermined condition a or the predetermined conditions b and c, the display 2
7 and the display function of the display 27 is turned off.
F.

Since the fishing reel 51 according to the present embodiment is constructed as described above, the actual fishing is performed as shown in FIG. When fishing is performed with the slip stop position set at 2 m and the shelf position set at 50 m (step S1), the control means 21
CPU determines whether the fishing line is to be fed or wound from the rotation direction of the spool 11 based on the rotation pulse signal of the spool 11 read from the reed switch 33a (step S).
2).

If it is determined in step S2 that the fishing line is being paid out, the CPU determines whether or not the line length L calculated by the above-described equations (1) to (3) is within the range of the predetermined condition a. If the predetermined condition a is not satisfied, that is, if it is determined in step S3 that the device has not been advanced by 10 m, the process proceeds to step S4, and the display 27 displays the thread length L as usual. Then, returning to steps S2 and S3 again, the CPU monitors whether or not the thread length L is within the range of the predetermined condition a. If it is determined in step S3 that the yarn length L satisfies the predetermined condition a, the CPU proceeds to step S5. The CPU cuts off the power supply from the battery power supply to the display 27, and turns off the display function of the display 27 (step S5). Then, returning to steps S2 and S3 again, the CPU determines that the thread length L
To see if it is in the range
If it is determined in step S3 that the thread has descended to the point of 0 m, the thread length L is displayed on the display 27 again.

Therefore, if the angler turns on the clutch at the shelf position while watching such a display, accurate shelving can be performed. On the other hand, if it is determined in step S2 that the fishing line is to be wound based on the rotation pulse signal of the spool 11 read from the reed switch 33a, the process proceeds to step S6, where CP is determined.
U monitors whether or not the measured yarn length L is within the range of the predetermined condition b.
If it is determined that there is still a device within 10 m from the shelf position, the process proceeds to step S4 and the display 2
7 displays the thread length L as usual. Then, returning to steps S2 and S3 again, the CPU monitors whether or not the thread length L is within the range of the predetermined condition b. If it is determined in step S6 that the predetermined condition b is satisfied, the CPU proceeds to step S6. S7
To monitor whether or not the winding speed S is within the range of the predetermined condition c.
When the determination is made in step S4, the process proceeds to step S4, where the thread length L is displayed on the display 27 as usual.

If it is determined in step S7 through steps S2 and S6 that the winding speed S satisfies the predetermined condition c, the fishing line is wound at a high speed and the display changes rapidly, making it impossible for the angler to determine. As there is, CPU
Turns off the power supply from the battery power supply to the display 27, and turns off the display function of the display 27 (step S8).
Then, if it is determined that the tackle has been wound up to a position 10 m from the boat stop position in step S6 after step S2 again, the yarn length L is displayed on the display 27 again.

Therefore, the angler can look at such a display, and
When the fishing line is wound by the operation of the power lever 17 and the tackle arrives at the berthing stop position, the CPU sends a motor stop command to the spool motor drive circuit 45 to stop the spool motor 13 and an alarm. An operation command is sent to the drive circuit 47 to activate the alarm 49,
Further, when the mechanism reaches the boat-slip stop position by the winding operation of the handle 15, the CPU activates the alarm 49 via the alarm drive circuit 47.

As described above, according to the present embodiment, the "predetermined conditions a to c for the rotational operation state of the spool associated with the feeding or winding of the fishing line" are set such that the display of the line length is not necessary when feeding or winding the fishing line. Therefore, when the predetermined conditions a to c are satisfied, the power supply to the display 27 is cut off and the display function is turned off.
Since it is configured to be FF, according to the present embodiment,
In addition to being able to check the position of the tackle during standby, while maintaining the function of the line length measuring device, unnecessary power consumption during fishing operation is suppressed and an efficient power saving effect that matches actual fishing is obtained. The life of the battery power has been improved by several steps compared to the past.Especially for fishing reels that use small batteries, the longer life of the battery power makes it possible to enjoy fishing operations for a long time with peace of mind. Was.

In the above embodiment, the predetermined conditions a to
c is stored in the ROM of the control means 21. However, a mode changeover switch is provided on the reel body, and the predetermined conditions as described above are input to the RAM of the control means 21 and changed in the input mode of the control means 21 by the mode changeover switch. It may be made possible, and the intended purpose can be achieved by such an embodiment as in the above embodiment.

[0027]

As described above, according to the fishing reel of the first aspect, not only can the position of the tackle be confirmed at the time of standby, but also the fishing reel can be operated while maintaining the function of the line length measuring device. In this way, it is possible to obtain an efficient power saving effect in line with actual fishing by suppressing unnecessary power consumption at the time of fishing, so that the life of the battery power supply is improved by several steps compared to the conventional type, especially for fishing reels using small batteries. The longer life of the battery power supply means that fishing operations can be enjoyed for a long period of time.
