Description

[Technical field]

[0001] The present invention relates to a fishing reel capable of calculating the length of a fishing line when cast, an information processing device, and a fishing information processing system having the same. [Background technology]

[0002] Conventionally, various spinning reels capable of releasing fishing line have been known. When fishing with such a spinning reel, the angler has to rely on his or her senses to determine how much of the fishing line has been released when casting a lure or bait.

[0003] For example, Patent Document 1 discloses a fishing reel that can detect the reeling or unreeling of a fishing line. The fishing line detection device for a spinning reel is configured to detect the fishing line being wound onto or unreeled from the spool. The fishing line detection device has a light emitting section and a light receiving section that receives the light emitted from the light emitting section, and the sensor that detects the fishing line in a non-contact manner when the fishing line is being wound onto or unreeled from the spool is mounted on a stationary member of the spinning reel or on a fishing rod to which the spinning reel is attached.

[0004] Patent Document 2 discloses a counter device for a spinning reel that converts the amount of fishing line wound up, which corresponds to a predetermined amount of operation of a driver that operates when winding the fishing line onto a spool, into comprehensible data and stores this data in a memory means when the fishing line is wound up, and also measures the amount of operation of the driver until winding of the fishing line is completed when the cast out tackle is reeled in from a predetermined position, and includes a control means that reports the distance between the device and the predetermined position based on the measurement results and the data stored in the memory means.

[0005] [Patent Document 1] JP 2006-081527 A [Patent Document 2] Japanese Utility Model Application Publication No. 4-009565 Summary of the Invention [Problem to be solved by the invention]

[0006] However, even if the photoelectric sensor in Patent Document 1 is used to measure the length of the fishing line, there is a problem that it is actually difficult to accurately detect the length of the fishing line, because it may be erroneously detected due to the influence of external light. In addition, the method in Patent Document 2 requires the user to press a reset button after starting to cast, so if the user forgets to press the button or presses the button at any time other than when casting begins, the line length cannot be calculated accurately. In addition, when the fishing line is released by the drag force when a fish is hooked, even if the length of the fishing line is calculated from the amount of operation of the driver, it deviates from the actual casting distance of the fishing line, making it difficult to accurately grasp the line length.

[0007] The present invention has been made in consideration of the above circumstances, and its object is to provide a fishing reel, an information processing device, and a fishing information processing system equipped with the same that can more accurately calculate the casting distance of a fishing line (the length of the released fishing line) and inform the angler of this when fishing using a fishing reel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] Hereinafter, embodiments of the fishing reel and the like according to the present invention will be described in detail with reference to the accompanying drawings. Components common to multiple drawings are designated by the same reference numerals throughout the multiple drawings. Please note that the drawings are not necessarily drawn to scale for the sake of convenience.

[0025] First, with reference to FIG. 1, a configuration of a fishing reel 1 according to an embodiment of the present invention will be described.

[0026] As shown in the figure, a fishing reel 1 according to one embodiment of the present invention comprises a throw detection unit 2 which includes a throw start detection unit which detects the start of throwing and a throw end detection unit which detects the end of throwing, a handle rotation detection unit 3 which detects the number of rotations of the handle of the fishing reel 1, and a line length calculation unit 4 which calculates the length of the released fishing line, and the line length calculation unit 4 is configured to calculate the length of the fishing line based on the number of rotations of the handle detected by the handle rotation detection unit 3 from the start of throwing to the end of throwing.

[0027] According to a fishing reel 1 of one embodiment of the present invention, it is possible to provide a fishing reel that can more accurately calculate the casting distance of the fishing line (the length of the released fishing line) when fishing and inform the angler of this.

[0028] As shown in FIG. 1, a fishing reel 1 according to one embodiment of the present invention includes a memory unit 5, which can store at least one or all of the following information: the start of casting, the end of casting, the number of handle rotations, and the length of the fishing line.

[0029] As shown in the drawings, the fishing reel 1 according to one embodiment of the present invention includes a display unit 6, which can display the length of the fishing line. This makes it possible to inform the angler of the distance the fishing line has traveled (the length of the released fishing line) when fishing. The display unit 6 may also be configured to display at least one of the information on the start of casting, the end of casting, and the number of rotations of the handle. A separate output unit (not shown) may also be provided, which makes it possible to inform the angler of the distance the fishing line has traveled (the length of the released fishing line) by voice or the like when fishing. The output unit can output various types of information other than voice, and is not limited to a specific form.

[0030] Furthermore, as shown in the drawings, the fishing reel 1 according to one embodiment of the present invention includes a transceiver unit 7 including a transmitter and a receiver, and is configured to transmit information about the length of the fishing line to an external device by the transmitter of the transceiver unit 7. Here, the external device refers to, for example, a computer, a smartphone, smart glasses, a smart watch, or a fishing device, but is not limited to these.

[0031] Here, the length of the fishing line is calculated for each cast, and the timing of the end of each cast is determined based on the detection of the end of the current cast or the start of the next cast. After the line length for the current cast is calculated, the calculation result is stored in the memory unit 5, and then the calculated current line length is initialized (reset) in order to calculate the line length for the next cast. The number of handle rotations may also be initialized (reset). This makes it possible to prevent the line length for each cast from being mixed up.

[0032] Furthermore, in the fishing reel 1 according to one embodiment of the present invention, the end of the current throw can be determined based on detection of the start of the next throw by the throw start detection section of the throw detection unit 2. This is because when the start of the next throw is detected, it also means the end of the current throw, so by determining the detection of the start of the next throw as the detection of the end of the current throw, the information on the detection of the start of the throw can be used more effectively.

[0033] In the fishing reel 1 according to one embodiment of the present invention, when the throw start detection section and the throw end detection section of the throw detection section 2 are the bail, the throw end of the current throw may be determined by detecting the operation of the bail operated during throwing. This has the advantage that throw detection can be performed without the angler having to perform additional actions such as pressing a button.

[0034] 1, a fishing reel 1 according to one embodiment of the present invention includes a drag release amount detection unit 8 that detects the amount of drag release, and a line length calculation unit 4 is configured to calculate the length of the fishing line by subtracting a difference based on the amount of drag release detected by the drag release amount detection unit 8 from the length of the fishing line based on the number of handle rotations. Also, in the fishing reel 1 according to one embodiment of the present invention, the amount of drag release can be initialized based on detection of the end of casting or the start of casting.

[0035] According to the fishing reel 1 of one embodiment of the present invention, it becomes possible to more accurately calculate the casting distance of the fishing line (the length of the released fishing line) when fishing.

[0036] Next, a method for calculating the length of the fishing line released by the fishing reel 1 according to one embodiment of the present invention will be described in more detail with reference to FIG.

[0037] First, in step S1, it is determined whether throwing has ended. If throwing has ended, the process proceeds to step S7, where the calculated line length data is transmitted (or stored). Then, the process proceeds to step S8, where the line length data is initialized (reset). At that time, the number of handle rotations may be initialized (reset).

[0038] In step S1, it is determined whether casting has ended. If casting has not ended, i.e., casting is still in progress, the process proceeds to step S2, where it is determined whether the fishing reel handle is rotating. If the handle is not rotating, the process proceeds to step S4. If the handle is rotating, the process proceeds to step S3, where the length A of the fishing line retrieved (released) is calculated based on the number of rotations of the handle.

[0039] Next, the process proceeds to step S4 to determine whether the spool is rotating. If the spool is not rotating, the process proceeds to step S6 to determine the line length A as the line length C of the retrieved (released) fishing line. On the other hand, if the spool is rotating, the process proceeds to step S5 to calculate line length B based on this. Then, the process proceeds to step S6 to calculate the line length C of the retrieved (released) fishing line as line length A - line length B.

[0040] In this way, when fishing, it is possible to more accurately and reliably calculate the amount of fishing line released, i.e., the length of the fishing line retrieved.

[0041] Next, a fishing information processing system according to an embodiment of the present invention will be described with reference to Fig. 3. As shown in the figure, the fishing information processing system 100 according to an embodiment of the present invention includes a fishing reel 1 having a throw detection unit 2 including a throw start detection unit that detects the start of throwing and a throw end detection unit that detects the end of throwing, a handle rotation detection unit 3 that detects the number of rotations of the handle of the fishing reel 1, and an information processing device 10 having a line length calculation unit 14 that calculates the length of the released fishing line, and the line length calculation unit 14 is configured to calculate the line length of the fishing line based on the number of rotations of the handle detected by the handle rotation detection unit 3 from the start of throwing to the end of throwing.

[0042] Furthermore, as shown in the figure, in the fishing information processing system 100 according to one embodiment of the present invention, the information processing device 10 includes a transmitting / receiving unit 17, which is configured to receive information on the start of casting, the end of casting, and the number of rotations of the handle of the fishing reel 1 from the fishing reel 1. The information processing device 10 also includes a memory unit 15, which can store this information.

[0043] Furthermore, in the fishing information processing system 100 according to one embodiment of the present invention, the transmitting / receiving unit 17 of the information processing device 10 can transmit the calculated fishing line length information to the fishing reel 1. In this way, the fishing reel 1 can receive line length information from the outside and display it on the display unit 6. This can eliminate the load of line length calculation processing on the fishing reel 1. Also, a separate output unit (not shown) can be provided to receive line length information from the outside and inform the angler of the line length by voice or the like. The output unit can output various types of information other than voice, and is not limited to a specific form.

[0044] As shown in FIG. 3, in the fishing information processing system 100 according to one embodiment of the present invention, the information processing device 10 includes a display unit 16, which is configured to display the calculated fishing line length. The display unit 16 can also display information about general fishing information, including the start of casting, the end of casting, and the number of rotations of the handle of the fishing reel 1. In this way, it is possible to centrally manage fishing information in an information processing device outside the fishing reel. In addition, a separate output unit (not shown) can be provided to inform the angler of general fishing information by voice or the like. The output unit can output various types of information other than voice, and is not limited to a specific form.

[0045] In the fishing information processing system 100 according to an embodiment of the present invention, the information processing device 10 is a mobile terminal, a wearable terminal, or a computer device. More specifically, it may be a smartphone, smart glasses, a smart watch, or a fishing dedicated device. The information processing device 10 may be various devices other than these, and is not limited to a specific device.

[0046] As described above, the information processing device 10 according to one embodiment of the present invention comprises a transceiver unit 17 having a receiver that receives information from the outside (the fishing reel), and a line length calculation unit 14 that calculates the length of the fishing line, and the receiver receives information on the start of casting, the end of casting, and the number of rotations of the handle from the outside (the fishing reel), and the line length calculation unit 14 is configured to calculate the length of the fishing line based on this information.

[0047] Next, the above-mentioned handle rotation detection unit 3 will be described in more detail with reference to Fig. 4. As shown in the figure, the fishing reel 1 according to one embodiment of the present invention includes the handle rotation detection unit 3 that detects the number of rotations of the handle, and the handle rotation detection unit is composed of a slit plate 22 and a photo interrupter 23, and detects the number of rotations of the handle by measuring the rotation of the slit plate 22 attached to the handle shaft 21 by the photo interrupter 23. Here, the object of measurement is not limited to this, and may be a gear or the like synchronized with the rotation of the handle or a rotor whose speed is increased by a gear ratio. Also, the detection method may be by using something other than a photo interrupter, and is not limited to a specific mode.

[0048] Next, the above-mentioned throwing detection unit 2 will be described in more detail with reference to FIG. 5. As shown in the figure, the fishing reel 1 according to one embodiment of the present invention includes the throwing detection unit 2 that detects the start and end of throwing. As shown in FIG. 5, a magnet 25 is attached to the bail part 24, and a Hall element 27 is attached to the reel foot part 26, so that the start and end of throwing can be detected by detecting the movement of the bail part 24. Here, various methods can be considered for detecting throwing other than detecting the movement of the bail part. For example, a method of detecting acceleration that may change due to throwing, a method of detecting the movement of an operating object that swings during a throwing operation, and a method of detecting the release speed of the fishing line can also be considered. Other methods will be described later. The throwing detection method is not limited to a specific embodiment.

[0049] Next, the drag release amount detection unit 8 will be described in more detail with reference to FIG. 6. As shown in the figure, the fishing reel 1 according to one embodiment of the present invention includes a drag release amount detection unit 8 that detects the drag release amount. As shown in FIG. 6, when the spool 28 rotates due to the drag, a magnet 30 is attached to a rotating body 29 connected to rotate synchronously with the spool 28, and the rotation of the rotating body 29 to which the magnet 30 is attached, which is accompanied by the rotation of the spool 28, is detected by a Hall element 31, thereby calculating the rotation amount of the spool and calculating the drag release amount. Here, various methods are conceivable for detecting the rotation of the spool, and for example, a method of attaching a Hall element to the drag knob and attaching a magnet to the spool, a method of placing a photosensor inside the spool, and a slit plate or a reflector inside the spool are conceivable. The method of detecting the rotation of the spool can be variously considered, such as a detection point, a detected part, and a sensor, and is not limited to a specific method.

[0050] Next, a method for calculating the length of the released fishing line based on detection of the bail operation will be described in more detail with reference to Fig. 7. As shown in the figure, in a fishing reel 1 according to one embodiment of the present invention, when the method for detecting the casting is the bail operation detection method, the operation of the bail operated at the time of casting is detected, and this is used as a trigger to start data detection.

[0051] As shown in the figure, the rotation of the handle and the rotation state of the spool are monitored, and when the handle rotates, the recovered line length L1 is calculated from the amount of rotation, and when the spool rotates, the released line length L2 is calculated from the amount of rotation. When the handle rotates and the spool does not rotate, the recovered line length (recovered distance) is L3 = L1. When the handle rotates and the spool rotates, the released line length (estimated flight distance) is L3 = L1 - L2. After that, when the bail is activated, it is determined that the casting is over, and the calculated line length is output as the estimated flight distance L3. Here, in the case of a normal spinning reel (excluding reels with lever brakes), when the line is released, each part that makes up the reel does not rotate or move, and is in a stationary state. For this reason, even if the parts inside the reel are measured, the amount of released line cannot be detected. However, in normal fishing, the fishing line is almost always the same length at the start of casting, so if the stretching or breakage of the fishing line can be ignored, the amount of fishing line retrieved up to the start of casting can be measured and regarded as the amount of fishing line that was released just before.

[0052] Alternatively, the throwing detection unit can use the acceleration value from an acceleration sensor attached to a fishing rod, fishing reel, etc. In this case, a certain threshold value is set for the acceleration value, and when this threshold value is exceeded, it is determined that the throw has started, and various detection and calculation processes and their output can be performed.

[0053] The detection information during each throw may be constantly output, and various output devices may be constantly displaying the current winding amount, the amount released by drag, etc. For the next throw, these output information related to the previous throw are initialized (reset).

[0054] Next, a method for outputting the average speed of the handle rotation will be described with reference to FIG. 8. As shown in the figure, in the fishing reel 1 according to one embodiment of the present invention, when the average speed of rotation of the handle of the fishing reel 1 is output, after the operation of the bail is detected during the casting operation, the line slack is retrieved and the lure is submerged to a desired water depth. In order to ignore the rotation speed during this period, the microcomputer's timer function acquires the time T1 at, for example, the fifth rotation after the start of the lure retrieval operation, and the microcomputer's timer function acquires the time T2 again at the 15th rotation after the start of the retrieval operation. The handle rotation speed between T1 and T2 is acquired, and the average speed V1 of the handle rotation between T1-T2 at the time T2 is acquired is calculated. The lure is retrieved and the operation of the bail at the next casting is detected, and V1 can be output. This has the advantage that when the angler performs the next or subsequent casting and tries to reproduce the stored handle rotation speed before the previous time, the angler can refer to the handle rotation speed calculated more accurately.

[0055] Next, a method for correcting the line length of the released fishing line will be described with reference to Figures 9a and 9b. The line length correction method shown in the figures calculates a correction value for the line length recovered (released) with respect to the number of handle rotations N based on the relationship between the bottom diameter D of the spool 28 measured in advance and the number of handle rotations N required to wind the wound line length L, thereby correcting the amount of line recovered (released) Z per rotation of the spool 28, which is caused by the diameter D' changing due to the recovery (release) of the fishing line, and calculating the line length. The amount of line recovered (released) Z can be expressed as follows: Recovery amount (release amount) Z = Handle rotation speed N x gear ratio x line length correction value In this way, a more accurate calculation of the yarn length can be performed.

[0056] Next, with reference to Figures 10a and 10b, another aspect of the method for detecting the end of casting by the fishing reel 1 according to one embodiment of the present invention will be described. As shown in the figures, the fishing reel 1 according to one embodiment of the present invention includes a casting detection unit that detects the end of casting (start of casting), and as shown in Figures 10a and 10b, a detectable part 33 configured to protrude with the operation of the bail part is provided on the rotating part 31 side of the fishing reel, and a detection part 34 is provided on the main body part 32 side of the fishing reel 1 so as to come into contact with the detectable part 33 when the detectable part 33 protrudes (as shown in Figure 10b). In this way, the end of casting (start of casting) can be detected by detecting the contact of the detectable part 33 with the detection part 34 caused by the operation of the bail part.

[0057] Next, referring to Figs. 11a and 11b, another aspect of the method for detecting the end of casting by the fishing reel 1 according to one embodiment of the present invention will be described. As shown in the figures, the fishing rod 30 provided with the fishing reel 1 according to one embodiment of the present invention includes a casting detection unit for detecting the end of casting (start of casting), and as shown in Figs. 11a and 11b, a detectable part 35 is provided on the fishing line, and a detection part 36 such as a non-contact limit switch is provided on the fishing rod 30, and the detection part 36 detects the approach of the detectable part 35 (Fig. 11b). In this way, the end of casting can be detected by detecting the approach of the detectable part 35 provided on the fishing line to the detection part 36. Here, in the illustrated example, the detection part 36 is provided on the fishing rod 30, but the detection part 36 may be provided on the fishing reel 1.

[0058] Next, with reference to FIG. 12, another aspect of the method for detecting the end of casting by the fishing reel 1 or the like according to one embodiment of the present invention will be described. As shown in the figure, a detection unit 38 for detecting the end of casting (start of casting) is provided on another fishing tackle near the fishing reel 1 according to one embodiment of the present invention. On the other hand, a detected part 37 is provided on the fishing line, and the detection unit 38 is configured to be able to determine the communication state and distance with the detected part. In this way, based on the communication state (communication possible state, communication cut-off state) or distance (less than a predetermined distance, more than a predetermined distance) with the detected part 35 provided on the fishing line, it is possible to detect the end of casting (start of casting). Here, in the illustrated example, the detection unit 38 is described as being provided on the other fishing tackle, but the detection unit 38 may be provided on the fishing reel 1 or the fishing rod 30.

[0059] Next, another embodiment of the handle rotation detector 3 and the drag release amount detector 8 in the fishing reel 1 according to one embodiment of the present invention will be described with reference to Fig. 13. Here, the drag mechanism can be realized by a system in which the rotor and the handle rotate relatively in addition to the system in which the spool and the main shaft rotate relatively as shown in Fig. 6 above. Hereinafter, the system will be described in more detail with reference to Fig. 13.

[0060] As shown in Fig. 13, the spool 28 is fixed to a main shaft (main shaft) 39, which is supported non-rotatably relative to the reel body 40. In this case, an oscillator mechanism may be provided that moves the main shaft 39 up and down in the axial direction in response to the rotation of the rotor 41 to evenly wind the fishing line around the spool 28. A conventionally known oscillator mechanism may be used as appropriate for this oscillator mechanism, and is omitted in Fig. 13 for simplification.

[0061] The rotor 41 is fixed to the pinion gear 42, and receives rotation from a face gear 43 of the pinion gear 42. A drag mechanism is provided between the rotor 41 and the handle 44. This allows the rotor 41 to rotate freely relative to the handle 44 when torque exceeding a set value is received, thereby preventing the fishing line from breaking. In the illustrated example, a conventionally known drag mechanism is provided between the handle 44 and the face gear, but the same function can be achieved by providing a drag mechanism between the pinion gear 42 and the rotor 41.

[0062] In the configuration shown in FIG. 13, the amount of recovered line can be obtained by reading the number of rotations of the rotor 41. For this purpose, a detected part (e.g., rotor detected part 45) is provided on the rotor 41 or a part that rotates dependently on the rotor 41 (the rotor itself, the pinion gear, the face gear, etc.), and a detection part (e.g., rotor detection part 46) is provided at a location on the reel body 40 facing the detected part. The amount of recovered line can be obtained from the output value of the rotor detection part 46. Here, the specific configuration of the rotor detection part 46 can be realized in a similar manner to that shown in FIG. 4.

[0063] The drag release amount may also be obtained by obtaining the difference between the rotor rotation speed and the handle rotation speed.
