2. Description of the Related Art In recent years, many fishing reels have been equipped with a thread length measuring device for measuring the amount of fishing line, that is, the thread length, based on the number of rotations of a spool. It is possible to lower the tackle to a predetermined shelf position, or to display the flying distance of the tackle up to the point when throwing.

The applicant of the present invention has previously disclosed the Japanese Patent Laid-Open No. 5-10.
In Japanese Patent No. 3567 and Japanese Utility Model Laid-Open No. 7-7435, a yarn length measuring device capable of measuring the yarn length regardless of the type of fishing line used is disclosed. The yarn length measuring device disclosed in Japanese Unexamined Patent Publication No. 5-103567 sets a specified winding diameter level at a position smaller than the maximum winding diameter of the spool and winds the fishing line up to the specified winding diameter level. The number of rotations of the spool and the total number of rotations of the spool when the fishing line is wound up to the full length of winding are detected by the number of rotations detecting means, and the basic data of the number of rotations of these spools and the diameter of the line up to the specified winding diameter level and the spool After the yarn length calculation formula is determined by the shape, the yarn length calculation formula is calculated based on the actual number of rotations of the spool, and the calculated value is displayed on the display as the yarn length.

The yarn length measuring device disclosed in Japanese Utility Model Laid-Open No. 7-7435 measures the yarn length by using an ultrasonic sensor, and includes a rotational speed detecting means for detecting the rotational speed of a spool and a transmitting device. The time until the ultrasonic wave emitted from the ultrasonic sensor on the fishing line winding surface of the spool is received by the ultrasonic sensor for receiving is measured by the time measuring means, and the diameter of the spool is calculated and measured based on the measured value. And a display for displaying the thread length calculated by this calculating means, a means for calculating the thread length based on the diameter of the thread obtained by the diameter measuring means for the thread winding and the value detected by the rotation speed detecting means.

However, in the yarn length measuring device using the ultrasonic sensor as described above, 200 mA (milliampere) is required when the ultrasonic sensor is used.
A back and forth current is required, which is disclosed in JP-A-5-103567.
In comparison with the starting current value of 300 μA (microampere) required by the yarn length measuring device disclosed in Japanese Patent Publication, the power consumption is remarkably large.

In that case, the decrease in current and voltage due to the power consumption was remarkable. And
When the display is a digital display, the voltage is usually 2.7V.
If it is less than the (bolt), the display becomes invisible, but if the yarn length is measured by the ultrasonic sensor with the manual reel as described above, the yarn length measuring device disclosed in Japanese Unexamined Patent Publication No. 5-103567 is used. Compared with the case where the display was on, there was a problem that the display on the display disappeared quickly and the yarn length could not be confirmed.

The present invention has been devised in view of the above circumstances, and provides a fishing reel capable of maintaining the function of the yarn length measuring device, particularly the function of an indicator for displaying the yarn length, for a long period of time.

The reflected wave can be satisfactorily received by the ultrasonic sensor 59.

The clutch lever 23 is the clutch O
Due to the structure that moves by N / OFF operation, if the distance between the ultrasonic sensors 57 and 59 mounted in the clutch lever 23 and the fishing line winding surface changes due to the clutch operation, accurate thread length measurement can be performed. Can not. Therefore, in the present embodiment, as shown by the chain double-dashed line in FIG.

As shown in FIG. 2, between the side plates 7 and 9 below the level wind mechanism 29, there is provided a power supply case 71 into which a plurality of dry batteries 69a can be mounted. The dry battery 69a installed in the main body 71 is used as the main power source 69 of the main yarn length measuring device using the ultrasonic sensors 57 and 59.
It is designed to be used as.

Further, as shown in FIG. 1, a power supply case 75 having a button battery 73a mounted therein is provided in one of the side plates 7, and in this embodiment, the button battery 73 is provided.
A is used as an auxiliary power source 73 of an auxiliary yarn length measuring device described later.

Then, in the electronic control mechanism housing 37,
The same yarn length measuring device as the yarn length measuring device disclosed in Japanese Utility Model Laid-Open No. 7-7435 is incorporated. As is well known in the art, this yarn length measuring device has a yarn winding diameter measuring means based on the time until the ultrasonic sensor 59 receives the reflected wave of the ultrasonic wave emitted from the ultrasonic sensor 57 to the fishing line winding surface. The diameter of the bobbin is measured, the thread length calculating means calculates the thread length based on the measured value and the detected value of the rotation speed detecting means 39, and the calculated value is used as the fishing line 19
The thread length of the ultrasonic sensors 57 and 59 is displayed on the digital display 49.
In the actual fishing, the main yarn length measuring device first measures the yarn length before the auxiliary yarn length measuring device described below.

That is, as described above, the ultrasonic sensor 5
Since this type of yarn length measuring device using 7, 59 can measure the yarn length with high accuracy, this embodiment first uses this yarn length measuring device as the main yarn length measuring device. However, in the manual reel, which does not use an external battery having a large capacity as a power source, as in the present embodiment, the yarn length measurement by the ultrasonic sensors 57 and 59 consumes a large amount of power, so that the current and voltage are significantly reduced, and the ultrasonic sensor 57 is used. , 59 may not operate immediately or the display of the digital display 49 may become invisible, especially when the voltage is below 2.7V.
When the display of No. cannot be confirmed, the fisherman cannot confirm the thread length, no matter how accurately the thread length can be measured.
It becomes impossible to achieve the intended purpose.

Therefore, in this embodiment, in addition to the main yarn length measuring device, an auxiliary yarn length measuring device is disclosed in Japanese Patent Laid-Open No. 5-1035.
The same yarn length measuring device as the yarn length measuring device disclosed in Japanese Patent No. 67 is incorporated in the control means as an auxiliary yarn length measuring device. As shown in FIGS. 1 and 2, this auxiliary thread length measuring device sets a specified winding diameter level 77 at a position smaller than the maximum winding diameter of the spool 1 and winds the fishing line 19 up to the specified winding diameter level 77. The number of rotations of the spool 1 at the time of winding and the total number of rotations of the spool 1 at the time of winding the fishing line 19 up to the full length of winding are detected in advance by the number-of-rotations detecting means 39, and the number of rotations of the spool 1 and the specified number of windings are detected. After determining the thread length calculation formula with the basic data of the thread winding diameter up to the diameter level 77 and the spool shape,
The yarn length calculation formula is calculated and executed based on the actual number of revolutions of the spool 1 at the time of actual fishing, and the calculated value is displayed as the yarn length on the digital display 49. It has low power consumption.

Although not shown, in this embodiment, a voltage measuring device for measuring the voltages of the main power source 69 and the auxiliary power source 73 is mounted in the reel unit 5, and the measured value is input to the control means. Further, the control means is preset and stored with a prescribed value (eg, 2.8 V) as a minimum voltage value sufficient to maintain the display of the digital display 49. Then, when the angler turns on the ON / OFF switch 79 installed on the operation panel 47 to activate the control means and the voltage measuring device, the control means operates the main yarn length measuring device by the main power source 69 and measures the voltage. The measured value from the instrument is input to determine whether the voltage value of the main power source 69 is less than or equal to a specified value.

When the voltage value of the main power source 69 becomes less than the specified value due to the power consumption of the main power source 69 due to the actual fishing, the control means automatically switches the main yarn length measuring device to the auxiliary yarn length measuring device. The power source 69 is switched to the auxiliary power source 73, and the auxiliary power source 73 operates the auxiliary yarn length measuring device to measure the yarn length. Further, as shown in FIG. 1, an alarm lamp 81 is mounted on the operation panel 47, and the control means controls when the voltage value of the main power source 69 becomes equal to or lower than a specified value.
Such an alarm light 81 is made to blink for several minutes, and when the voltage value of the auxiliary power source 73 becomes a specified value or less, the alarm light 81 is turned on to inform the fisherman of the battery replacement time. .

Since the fishing reel 83 according to the present embodiment is constructed in this way, a fisherman operates the ON / OFF switch 79 to turn it on as shown in the flow chart of FIG. When fishing is performed by activating the digital display 49 or the like (step S1), step S2
The yarn length is measured by the main yarn length measuring device, and as described above, the time until the reflected wave of the ultrasonic wave emitted from the ultrasonic sensor 57 is received by the ultrasonic sensor 59 is the thread winding diameter measuring means. Measures and the bobbin diameter is measured based on the measured value.

Then, the yarn length is calculated by the yarn length calculating means based on the yarn winding diameter and the detection value of the rotation sensor 39, and the calculation result is displayed on the digital display 49. Simultaneously with the yarn length measurement by the main yarn length measuring device, the control means inputs the measured value from the voltage measuring device and measures whether or not the voltage value of the main power source 69 is below the specified value (step S3). , When the voltage value of the main power source 69 becomes lower than the specified value due to power consumption,
The control means blinks the alarm lamp 81 for several minutes in step S4, and automatically switches from the main yarn length measuring device to the auxiliary yarn length measuring device, and also switches the main power source 69 to the auxiliary power source 73 to assist. The auxiliary yarn length measuring device is operated by the power source 73 to perform yarn length measurement (steps S5 to S7).

Then, the control means judges whether or not the voltage value of the auxiliary power source 73 has become less than or equal to the specified value due to the power consumption of the auxiliary power source 73 due to actual fishing (step S8). When the voltage value of the auxiliary power supply 73 becomes equal to or lower than the specified value, the warning light 81 is turned on to inform the fisherman of the battery replacement time (step S9).
It is good to replace a with the button battery 73a.

As described above, the fishing reel 83 according to this embodiment is provided with the main yarn length measuring device using the ultrasonic sensors 57 and 59 and the auxiliary yarn length measuring device not using the ultrasonic sensors, and these A main power source 69 and an auxiliary power source 73 are provided as power sources for operating, and the main power source 69 is used when operating the main yarn length measuring device which consumes a large amount of power, and the limit of the display on the digital display 49 is invisible. A value is set, and when the voltage value of the main power source 69 becomes equal to or lower than the specified value, the control means automatically and promptly switches to the auxiliary yarn length measuring device with low power consumption and switches to the auxiliary power source 73. , The auxiliary power source 73 having a smaller capacity than the main power source 69 can continue the yarn length measurement.
The display on the digital display 49 does not disappear immediately.

Therefore, according to the present embodiment, the function of the yarn length measuring device, particularly the function of the digital display 49, can be maintained for a long period of time. Further, according to the present embodiment, since the ultrasonic sensors 57 and 59 are mounted in the existing clutch lever 23, a supporting member for the ultrasonic sensor is separately provided on the reel unit, and the ultrasonic sensor is mounted on the supporting member. The reel body 5 can be made smaller than the conventional fishing reel.

FIG. 5 shows claims 1 to 3 and claim 5.
2 is a flowchart showing a method for controlling a fishing reel according to an embodiment of the present invention. In the present embodiment, first, a main power source operates a main yarn length measuring device to perform yarn length measurement, and a voltage value of the main power source is a prescribed value. When the following occurs, the control means automatically switches to the auxiliary power supply, and when the voltage value of the auxiliary power falls below the specified value, the main yarn length measuring device is automatically switched to the auxiliary yarn length measuring device. , The function of the digital display is maintained.

The present embodiment will be described below, but the same elements as those in the above embodiment are denoted by the same reference numerals. First, a first prescribed value (for example, 2.7 V) is preset and stored in the control means in the electronic control mechanism housing 37. When the angler turns on the ON / OFF switch 79 installed on the operation panel 47 to activate the control means and the voltage measuring device, the control means causes the main power source 69 to operate the main yarn length measuring device.

Then, the control means inputs the measured value from the voltage measuring device and measures whether or not the voltage value of the main power source 69 has become less than or equal to the specified value due to the power consumption of the actual fishing. And
When the voltage value of the main power source 69 becomes equal to or lower than the first specified value, the control means blinks the alarm lamp 81 on the operation panel 47 for several minutes and automatically switches from the main power source 69 to the auxiliary power source 73. The main yarn length measuring device continues to measure the yarn length.

Further, a second prescribed value (for example, 2.8 to 2.9 V) is preset and stored in the control means, and the voltage value of the auxiliary power source 73 is set to this value by the power consumption of actual fishing. When the value becomes equal to or less than the second specified value, the control means turns on the alarm lamp 81 and automatically switches from the main yarn length measuring device to the auxiliary yarn length measuring device to measure the yarn length by the auxiliary yarn length measuring device. It has become.

The rest of the structure is the same as that of the above-mentioned embodiment, so the structural description thereof will be omitted. Since the present embodiment is configured in this manner, the fisherman turns on the ON / OFF switch 79 to activate the control means, the voltage measuring device, the digital display 49, etc. as shown in the flowchart of FIG. (Step S10), the main yarn length measuring device measures the yarn length, and the measured value is displayed on the digital display 49 as the yarn length (step S1).
1).

Simultaneously with the yarn length measurement by the main yarn length measuring device, the control means inputs the measured value from the voltage measuring device to determine whether or not the voltage value of the main power source 69 has dropped below the first specified value. If the voltage value of the main power source 69 becomes less than or equal to the first specified value due to power consumption, the control means blinks the alarm lamp 81 for several minutes in step S13, and The main power source 69 is automatically switched to the auxiliary power source 73, and the yarn length measurement by the main yarn length measuring device is continued by the auxiliary power source 73 (steps S14 and S15).

Then, the control means next inputs the voltage value of the auxiliary power supply 73, and when it is determined in step S16 that the voltage value of the auxiliary power supply 73 has become less than or equal to the second specified value, the warning light 8
1 is turned on, the main yarn length measuring device is switched to the auxiliary yarn length measuring device, and the yarn length is measured by the auxiliary yarn length measuring device (steps S17 to S1).
9).

As described above, in the present embodiment, the main power source 69 is used when operating the main yarn length measuring device which consumes a large amount of power, and the first regulation is the limit at which the display of the digital display 49 becomes invisible. When a value is set and the voltage value of the main power source 69 becomes equal to or lower than the specified value, the auxiliary power source 73 is switched to ensure the display function of the digital display 49, and the voltage value of the auxiliary power source 73 is set to the first value due to power consumption. When the value falls to the second specified value, the auxiliary yarn length measuring device that consumes less power is automatically switched to ensure the display function of the digital display 49. Therefore, the auxiliary power source has a smaller capacity than the main power source 69. The yarn length measurement can be continued by 73, and the display of the digital display 49 does not disappear immediately.

Therefore, according to this embodiment as well, the function of the digital display 49 of the yarn length measuring device can be maintained for a long period of time. FIG. 6 shows claims 1 and 2.
And a flow chart showing a method for controlling a fishing reel according to the first embodiment of claim 5, in which the main power source is first operated by the main yarn length measuring device to measure the yarn length. When the voltage value falls below the preset first preset value, the control means automatically switches to the auxiliary yarn length measuring device, and when the voltage value of the main power source further falls below the second preset value. The main power supply is automatically switched to the auxiliary power supply.

The present embodiment will be described below. In this embodiment, the same parts as those in the embodiment of FIG. 1 are indicated by the same reference numerals. For the control means in the electronic control mechanism housing 37, first, a first specified value (for example, 2.8 to 2.9 V) is set.
Are preset and stored. And the fisherman is ON / O
When the FF switch 79 is turned on to activate the control means and the voltage measuring device, the control means causes the main power source 69 to operate the main yarn length measuring device.

Then, the main power source 6
When the voltage value of 9 becomes equal to or less than the first specified value, the control means blinks the alarm lamp 81 on the operation panel 47 for several minutes, and the auxiliary yarn length measuring device that consumes less power from the main yarn length measuring device. The yarn length is measured automatically by the auxiliary yarn length measuring device.

Further, a second prescribed value (for example, 2.7 V) is further set and stored in the control means, and the voltage value of the main power source 69 is the second value due to the power consumption of the auxiliary yarn length measuring device. When it becomes less than the specified value, it is difficult to maintain the function of the digital display 49 by the main power source 69 any more, and the alarm lamp 81 is turned on, and the main power source 69 is automatically switched to the auxiliary power source 73, so The length measuring device is operated by the auxiliary power source 73 to continue the yarn length measurement.

Since the other construction is the same as that of the embodiment shown in FIG. 1, the description thereof will be omitted. Since the present embodiment is configured in this way, the fisherman activates the ON / OFF switch 79 to activate the control means, the voltage measuring device, the digital display 49, etc., as shown in the flowchart of FIG. When done (step S20), first, the main yarn length measuring device measures the yarn length, and the measured value is displayed on the digital display 49 (step S21).

Further, as in each of the above-described embodiments, also in this embodiment, the decrease in the voltage value due to the power consumption of the main power source 69 is measured, and the voltage value of the main power source 69 is determined to be the first specified value in step S22. If it is determined that
Blinks for several minutes, the main yarn length measuring device is automatically switched to the auxiliary yarn length measuring device which consumes less power, and the yarn length is measured by the auxiliary yarn length measuring device (step S).
23-25).

Then, the control means, based on the measured value of the voltage measuring device, judges in step S26 that the voltage value becomes equal to or less than the second specified value due to the power consumption of the main power source 69,
The warning light 81 is turned on and the main power supply 69 is automatically switched to the auxiliary power supply 73, and the auxiliary power supply 73 operates the auxiliary yarn length measuring device to measure the yarn length (steps S27, 28).

As described above, also in this embodiment, when operating the main yarn length measuring device which consumes a large amount of power, first, the main power source 69 is used.
When the first specified value is set to the limit at which the display of the digital display 49 becomes invisible and the voltage value of the main power supply 69 becomes equal to or less than the specified value, the auxiliary yarn length measuring device that consumes less power When the voltage value of the main power supply 69 drops to the second specified value due to the power consumption of the auxiliary yarn length measuring device, the main power supply is no longer used. Since 69 is the limit, the main power supply 69 is automatically switched to the auxiliary power supply 73 to ensure the display function of the digital display 49, so that the display of the digital display 49 does not disappear immediately.

Therefore, according to the present embodiment as well, it is possible to maintain the function of the yarn length measuring device, particularly the function of the digital display 49, for a long period of time. FIG. 7 is a flow chart showing a method for controlling a fishing reel according to the second embodiment of claims 1, 2 and 5, and in this embodiment, one reel corresponding to the main power source is provided in the reel body. In addition to incorporating a power source, the yarn length is measured by the main yarn length measuring device and the auxiliary yarn length measuring device. First, the main yarn length measuring device is operated to measure the yarn length, and the voltage value of the power source is equal to or less than the specified value. Then, the control means automatically switches to the auxiliary yarn length measuring device to maintain the function of the digital display 49.

That is, a prescribed value (for example, 2.8 to 2.9 V) is preset and stored in the control means in the electronic control mechanism housing 37. Then, when the fisherman turns on the ON / OFF switch 79, the control means actuates the main yarn length measuring device by the power source and inputs the measured value from the voltage measuring device. Then, when the control means determines that the voltage value of the power source has become less than or equal to the specified value due to the power consumption of the actual fishing, the function of the digital display 49 is not maintained even if the main yarn length measuring device is operated. As it is difficult, the warning light 81 on the operation panel 47 is turned on, and the main yarn length measuring device is automatically switched to the auxiliary yarn length measuring device which consumes less power, so that the auxiliary yarn length measuring device measures the yarn length. It is supposed to be done.

Since the present embodiment is constructed in this way, the fisherman turns ON / O as shown in the flow chart of FIG.
By turning on the FF switch 79, a control means, a voltage measuring device,
When fishing is performed by activating the digital display 49 or the like (step S29), first, the main thread length measuring device measures the thread length, and the measured value is displayed on the digital display 49 (step S30).

Also in the present embodiment, as in each of the above embodiments, the control means inputs the measured value from the voltage measuring device,
When it is determined in step S31 that the voltage value of the power supply has become equal to or less than the specified value due to power consumption, the control unit determines in step S31.
At 32, the warning light 81 is turned on to warn the fisherman of that fact, and the main yarn length measuring device is automatically switched to the auxiliary yarn length measuring device which consumes less power to measure the yarn length by the auxiliary yarn length measuring device. It will be performed (step S33).

As described above, also in this embodiment, first, the highly accurate main yarn length measuring device is operated to measure the yarn length, and
A preset value is set in advance near the limit for ensuring the function of the digital display 49, and when the voltage value of the power source becomes equal to or less than the preset value, the auxiliary yarn length measuring device with low power consumption is automatically controlled by the control means. Since the display function of the digital display 49 is ensured by switching, the display of the digital display 49 does not disappear immediately.

As a result, according to the present embodiment as well, it is possible to maintain the function of the yarn length measuring device, particularly the function of the digital display 49, for a long period of time. In the above embodiment, only the voltage value of the power source is measured and the main yarn length measuring device is switched to the auxiliary yarn length measuring device, or the main power source is switched to the auxiliary power source. Both may be measured, or only the current value may be measured, and the main yarn length measuring device may be switched to the auxiliary yarn length measuring device or the main power source may be switched to the auxiliary power source. Also, similar to each of the above-described embodiments, it is possible to achieve the intended purpose.

The auxiliary yarn length measuring device is not limited to the yarn length measuring device as described above, and any other yarn length measuring device that consumes less power without using an ultrasonic sensor can be used. is there. Furthermore, each of the above embodiments is
Although the control means automatically switches from the main yarn length measuring device to the auxiliary yarn length measuring device, or from the main power source to the auxiliary power source, the reel unit is provided with a switching means such as a changeover switch and the like. The fisherman who confirms the blinking of may manually operate the switching means to switch from the main yarn length measuring device to the auxiliary yarn length measuring device, or to switch from the main power source to the auxiliary power source.

In addition, in each of the above-mentioned embodiments, the ultrasonic sensors 57 and 59 of the main yarn length measuring device are mounted on the clutch lever 23 which also serves as a thumb rest.
No. 23082, such as the yarn length measuring device disclosed in Japanese Utility Model Laid-Open No. 7-7435, in which an ultrasonic sensor is mounted on an electronic control mechanism housing so as to face the fishing line winding surface. It is needless to say that a yarn length measuring device having a structure in which a sensor support is attached to the lower part of the above and an ultrasonic sensor is attached thereto can be used as the main yarn length measuring device.

[0060]

As described above, according to the fishing reel according to each of the claims, even if the main thread length measuring device using the ultrasonic sensor consumes a large amount of power, the main thread length is measured by the control means. Since it is possible to switch the device to an auxiliary yarn length measuring device that consumes less power and to switch the power supply from the main power source to the auxiliary power source, the fisherman can use the yarn length measuring device to measure the yarn length during actual fishing. It has an advantage that it can be operated reliably, and in particular, even if the display is a digital display, its function can be maintained for a long period of time.

Further, according to the fishing reel of the fifth aspect, the fisherman further has an excellent effect that the consumption state of the power source can be confirmed.
