Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention is for fishing that can display the water depth at the tip of a fishing line fed out from the spool based on the relationship between the length of the fishing line wound around the spool having a winding length corresponding to the thickness of the fishing line and the rotational position of the spool. Reel related.
[0002]
[Prior art]
  2. Description of the Related Art A fishing reel such as a double-bearing reel or a single-bearing reel is provided with a water depth display device that displays the depth of a device set by the length of a fishing line fed from a spool (Japanese Patent Laid-Open No. 2-107908). . By providing this water depth display device, the device can be accurately lowered to the same shelf position, and the flying distance of the device can be displayed during throw fishing.
[0003]
  This type of water depth display device includes a yarn length measuring unit that measures the length of a yarn fed from the spool when the spool is rotated, and a water depth display that includes a liquid crystal display that displays the water depth based on the yarn length measured by the yarn length measuring unit. Part. The yarn length measuring unit calculates the yarn length from the number of rotations of the spool. Note that the spool winding diameter of the spool changes according to the number of rotations from the beginning of winding to the spool and the thickness of the thread, and the yarn length per one rotation of the spool changes with the spool diameter. Therefore, conventionally, the thread length is calculated from the spool rotation speed in consideration of the spool rotation speed and the thread thickness.
[0004]
  Specifically, a spool sensor for detecting the spool rotation position is provided on the reel, and a yarn length detector that contacts the outer periphery of the fishing line winding portion of the spool is mounted on the reel. When the fishing line is wound around the spool to the spoolable diameter, the relationship between the actual thread length measured by the thread length detector and the spool rotation position (spool rotation speed) detected by the spool sensor is learned at predetermined intervals. To do. Then, the learned relationship, that is, the relationship between the yarn length from the start of winding and the spoolable diameter to the spool rotation position is stored in the memory inside the reel.
On the other hand, when fishing, the yarn length detector is removed, the spool rotation position is detected by the spool sensor, the yarn length at that rotation number is read from the memory, and the yarn length is calculated from the spool rotation position.
[0005]
  There is also a type in which fishing line data in which the thickness (number), type (material), and length of a fishing line are designated is stored in advance in a memory. In this case, for example, the relationship between the spool rotation position and the length of the fishing line for each fishing line thickness (number) when the fishing line is wound up to the spool's spoolable diameter, or a parameter of a calculation formula representing the relation is previously stored in the memory. It is remembered.
[0006]
  On the other hand, the length of the fishing line when the fishing line is wound up to the spoolable diameter of the spool (the amount of winding) varies depending on the thickness of the fishing line. The amount of bobbin is determined by the volume of the bobbin and the thread guide pitch, but it is not a precise number for all numbers of fishing lines. For example, even if a certain number is 300 m, a fraction such as 220 m or 145 m may appear for a fishing line with a larger number. Since fishing lines are generally sold in units of 100 m, when such fractions are generated, there is a waste of purchasing extra fishing lines and throwing away the remainder. In order to prevent this waste, the shortage is compensated by using a lower winding thread. As this lower winding thread, a fishing line that is thicker than a newly wound fishing line is usually used.
[0007]
[Problems to be solved by the invention]
  However, it is difficult to know how much to wind the lower part of the fishing reel that has a water depth display function, especially when the lower spool is wound around the spool of the fishing reel in which the type and fishing line data is stored in the memory in advance. . If the thickness and type of the lower wound line and the newly wound fishing line are different, this is particularly noticeable and the preparation work is troublesome. Also, when winding fishing lines of the same thickness, the length of the lower winding to be wound must be measured, and the preparation work is troublesome.
[0008]
  An object of the present invention is to allow a plurality of fishing lines having different thicknesses to be easily wound around a spool of a fishing reel capable of displaying water depth without performing troublesome preparatory work up to the diameter that can be wound, and without producing fractions.

DETAILED DESCRIPTION OF THE INVENTION
  <Basic configuration for explaining the invention>
  A bobbin auxiliary tool 50 having a basic configuration for explaining the present invention shown in FIG. 1 is a synthetic resin or metal cylindrical member having an inner diameter that can be attached to the spool 10. The spool 10 includes a tubular bobbin trunk 10a and flanges 10b formed integrally at both ends of the bobbin trunk 10a. When the fishing line is wound around the bobbin trunk 10a up to a diameter capable of winding the fishing line (usually the diameter of the flange 10b), for example, the No. 4 fishing line 400, No. 5 350, No. 6 300 m , 8 can be wound around 200m.
[0016]
  The bobbin auxiliary tool 50 is a two-divided cylindrical body having semicircular half cylinders 50a and 50b. Concave and convex fitting portions 50c and 50d are formed at the split portions of the half cylinders 50a and 50b so that the half cylinders 50a and 50b are positioned in the radial direction.
[0017]
  Here, for example, the bobbin auxiliary tool 50 is formed to have substantially the same volume and shape as when No. 5 fishing line is wound around the spool 10 by 50 m. When the No. 5 fishing line is wound around the spool 10, if the fishing line is wound around the bobbin trunk 10 a to the full diameter that can be wound around the spool, it can be wound up to 350 m, resulting in a fraction of 50 m. For this reason, when the No. 5 fishing line is wound around the spool 10, 400m of fishing line sold in units of 100m must be purchased and discarded for 50m. However, when the above-described bobbin auxiliary tool 50 is used, the volume is formed so as to have the same volume and shape as when a No. 5 fishing line is wound 50 m from the bobbin trunk 10a. It can be wound up to a thread winding diameter. For this reason, fishing lines can be wound in units of 100 m, and it is not necessary to purchase extra fishing lines.
[0018]
  As shown in FIG. 2, the electric reel according to the present invention to which the bobbin winding tool 50 is mounted is a reel having a water depth display section that displays the water depth by the thread feeding length (or the thread winding length). The electric reel includes a reel body 1 mounted on the fishing rod R, a spool rotation handle 2 disposed on the side of the reel body 1, and a drag adjusting star drag disposed on the reel body 1 side of the handle 2. 3 is mainly provided.
[0019]
  The reel body 1 has a frame 7 composed of a pair of left and right side plates 7 a and 7 b and a plurality of connecting members 8 that connect them, and left and right side covers 9 a and 9 b that cover the left and right sides of the frame 7. A rotation shaft of the handle 2 is rotatably supported by the side cover 9b on the handle 2 side (right side in FIG. 1), and an external power source PS is connected to the side cover 9a opposite to the handle 2 (left side in FIG. 1). A connector 19 for connecting a power cord 18 is provided.
[0020]
  A spool 10 connected to the handle 2 is rotatably supported inside the reel body 1. Inside the spool 10, a direct-current drive motor 12 that rotates the spool 10 in the yarn winding direction is disposed. An operation lever 11 of a clutch (not shown) for turning on and off the drive transmission between the handle 2 and the motor 12 and the spool 10 is disposed on the side surface of the reel body 1 on the handle 2 side. When this clutch is turned on, the yarn unwinding operation can be stopped during the unwinding of the yarn due to its own weight.
[0021]
  Further, as shown in FIGS. 2 and 3, the reel body 1 includes a level wind mechanism 13 that operates in conjunction with the spool 10 and a transmission mechanism (not shown) that transmits the rotation of the handle 2 to the spool 10. Etc. are provided.
[0022]
  A counter case 4 is fixed to the upper portion of the reel body 1 as shown in FIGS. The counter case 4 includes a case main body 20 that is disposed on the top of the reel main body 1 and has a display opening 20 a formed on the upper surface thereof, and a bottom lid member 21 that closes the lower surface of the case main body 20.
[0023]
  The case body 20 is, for example, a synthetic resin molded product, and has a smooth outer peripheral surface that is continuously curved at the top of the reel body 1. The display opening 20a is closed by a display window 22 made of transparent resin.
[0024]
  The bottom lid member 21 is a plate-like member obtained by molding a conductive metal such as an aluminum alloy, and is attached to the case body 20 with screws.
On the upper surface of the counter case 4, as shown in FIG. 4, a water depth display unit comprising a liquid crystal display for displaying the water depth and shelf position of the device through the display window 22 on the basis of two standards, from the water surface and from the bottom. The operation key unit 6 is provided around the water depth display unit 5.
[0025]
  The water depth display section 5 is arranged on the right side of FIG. 4 of the water depth display area 5a of the 4-digit 7-segment display arranged in the center, the 3-digit bottom water depth display area 5b arranged below the water depth display area 5a. And a shift speed display area 5c. In addition, the water depth display 5 displays eight characters “from the bottom”, “learning”, “designation”, “second volume”, “correction”, “input”, “thread feed stop”, and “0 set”. Is possible. The characters “from the bottom” are displayed when the depth display mode is the bottom mode. The mode from the bottom is a mode for displaying the water depth of the device based on the bottom. Normally, the water depth of the device is displayed on the water surface standard (mode from the top). In addition, characters from “learn” to “input” indicate the type of the bobbin mode, and when any one is selected alternatively, the character of the selected bobbin mode is displayed.
[0026]
  The operation key section 6 has a shift key SK and a motor key PW arranged vertically on the right side of FIG. 1 of the water depth display section 5, and a bottom memo key SM and a mode key MD arranged vertically on the right side. .
[0027]
  The motor key PW is a toggle switch for turning on and off the motor 12 and increasing the speed of the motor 12 according to the on time.
[0028]
  The shift key SK is a key for increasing / decreasing the driven motor 12, and is a seesaw type switch having two upper and lower switches and a neutral position. Pressing the upper switch of the shift key SK increases the speed, and pressing the lower switch decelerates. Further, when the upper switch is pressed for a predetermined time or more when the motor 12 is not driven, the display mode can be switched between “from the top” and “from the bottom”. Further, when the lower switch is pressed for a predetermined time or longer, the yarn feed mode (a mode in which the motor 12 is driven with the clutch disengaged at the time of feeding to increase the yarn feed speed) can be turned on / off.
[0029]
  The bottom memo key SM is a switch that is pressed when the device reaches the bottom, and the water depth at that time is set as the bottom. When the bottom memo key SM is pressed for a predetermined time or more, the zero point of the water depth display can be set to a new position when the fishing line is cut.
The mode key MD is a switch for setting five types of bobbin winding modes. For example, when the switch is pressed once, the learning mode is set. When the button is pressed twice continuously, the designated mode is pressed. When the mode is pressed four times in succession, the correction mode is set. When the mode is pressed five times in succession, the spool mode is set as the input mode.
[0030]
  Here, the learning mode is a bobbin winding mode used when a fishing line of unknown thread diameter or length is wound around the spool 10, and the spool rotation speed at the final winding portion and the thread length per one rotation of the spool This mode is used to obtain the relationship between the spool rotation speed over the entire length of the fishing line and the thread length per rotation.
The designation mode is a mode used when the type, number, and length of fishing line prepared in the storage unit 43 are wound around the spool. In this designation mode, for example, the data for No. 4 400 m and the data for No. 5 350 m of the polyethylene multifilament material are stored in a predetermined area in the storage unit 43 in advance.
[0031]
  The lower winding mode is a mode used when winding a fishing line whose thread diameter or length is unknown after winding the lower thread to a previously specified thread winding diameter. In this lower winding mode, learning is basically performed with the same idea as the learning mode, except that the bobbin diameter at the start of winding is different.
The correction mode is a mode used to correct the shift when the display is shifted due to tension or the like, and is a mode configured to recalculate the inclination of the entire primary straight line obtained in the learning mode. The input mode is a mode configured to arbitrarily edit the total number of rotations of the spool and the predetermined distance feeding distance.
[0032]
  As shown in FIG. 3, a water depth display unit 5 and a reel control unit 30 that performs display control and motor control are arranged in the upper part of the counter case 4. A PWM drive circuit 31 that performs PWM drive of the motor 12 is disposed in the lower part of the counter case 4.
The reel control unit 30 includes a microcomputer including a CPU, a RAM, a ROM, an I / O interface and the like disposed in the counter case 4. The reel control unit 30 executes various control operations such as display control of the water depth display unit 5 and motor drive control according to the control program. As shown in FIG. 5, the reel control unit 30 includes various keys of the operation key unit 6, a spool sensor 41 for detecting the rotation direction and the number of rotations (rotation position data) of the spool 10, and a spool counter 42. It is connected. Further, the buzzer 40, the PWM drive circuit 31, the water depth display unit 5, the storage unit 43, and other input / output units are connected to the reel control unit 30.
The PWM drive circuit 31 includes an FET 32 as a drive element for driving the motor 12. The PWM drive circuit 31 is driven by the reel control unit 30 so that the duty ratio is controlled and the speed of the motor 12 is variably driven.
[0033]
  As shown in FIG. 2, the spool sensor 41 is composed of two reed switches 41a and 41b arranged side by side. The reed switches 41 a and 41 b detect a magnet (not shown) that rotates in conjunction with the spool 10. The number of rotations (rotation position) of the reel can be detected by counting the detection pulses with the spool counter 42. Further, the rotation direction of the spool 10 can be detected depending on which of the reed switches 41a and 41b has issued the detection pulse first.
[0034]
  The spool counter 42 is a counter that counts the number of times the spool sensor 41 is turned on and off, and rotational position data relating to the spool rotational speed is obtained from the count value SP. The spool counter 42 decreases when the spool 10 rotates in the forward direction (rotation in the yarn feeding direction) and increases when the spool 10 rotates in the reverse direction.
[0035]
  The storage unit 43 is composed of a nonvolatile memory such as an EEPROM, for example, and learning result data, various data used when calculating the yarn length, and the like are stored in the water depth display area. Further, the data of No. 4 and No. 5 fishing lines used in the designated mode are stored in a predetermined storage area different from the water depth display area.
[0036]
  Next, an outline of the yarn length calculation method in this embodiment will be described.
[0037]
  In the present invention, the yarn length L is calculated by utilizing the fact that the relationship between the yarn length Y per spool rotation and the spool rotation speed X can be approximated to a linear line.
[0038]
  It is assumed that the fishing line whose thickness and total length are unknown is wound around the spool 10 in a layered manner from the bobbin diameter Bmm, and all the fishing lines have been wound by c rotation. Next, when the Smm fishing line is unwound from that state, it is assumed that the spool 10 has rotated d times.
[0039]
  Now, the relationship between the spool rotation speed X and the yarn length Y per spool rotation can be defined by a linear line, with the horizontal axis representing the spool rotation speed X and the vertical axis representing the thread length per spool rotation. If the slope is A, it can be expressed by the following formula.
[0040]
  Y = AX + Bπ (1)
  Therefore, a graph showing the relationship between the spool rotation speed X and the yarn length Y per one rotation of the spool is as shown in FIG.
[0041]
  Now, Y (c) is the yarn length per rotation of the spool when the spool 10 is rotated c, and Y is the yarn length per rotation of the spool when the spool 10 is rotated a predetermined length S after winding up c rotations and then rotated d. Assuming (cd), these can be expressed as follows.
[0042]
  Y (c) = A · c + Bπ (2)
  Y (cd) = A · (cd) + Bπ (3)
  In the graph shown in FIG. 6, since the trapezoidal area indicated by hatching corresponds to the yarn unwinding length S after the end of winding, the yarn unwinding length S can be expressed as follows.
[0043]
  S = d · {Y (c) + Y (cd)} / 2 (4)
  Substituting Equations (2) and (3) into Equation (4),
  S = d · {A · c + Bπ + A · (c−d) + Bπ} / 2
  = D · {A · (2c−d) + 2Bπ} / 2 (5)
  Solving equation (5) with respect to slope A yields:
[0044]
  A = 2 (S−Bπd) / d (2c−d) (6)
  Therefore, it can be seen that the slope A of the linear line can be obtained by substituting the four data S, B, c, and d into the equation (6).
[0045]
  For example, if the spool 10 is wound at 2000 revolutions from the beginning of winding and the spool is rotated 60 meters when the spool 10 is unwound from there, assuming that the spool diameter of the spool 10 is 30 mm, the slope A of the linear straight line A Is as follows.
A = 2 (10000-94.2 * 60) / 60 (2 * 2000-60)
= 0.0368
  If the approximate linear line of the slope A and the intercept Bπ can be determined, the calculated slope A, the intercept Bπ, the total rotational speed c, the yarn length at the current rotational speed, and 0 set rotational speed (initially the same as the total rotational speed). Are stored in the water depth display area of the storage unit 43. When the spool 10 rotates during actual fishing, the stored data is read at a predetermined timing (for example, every rotation of the spool 20), and the linear length is integrated (area calculation processing) to obtain the yarn length LN at that time. be able to. Then, based on the obtained line length LN, the water depth of the device (water depth at the tip of the fishing line) is displayed on the water depth display unit 5.
[0046]
  In the storage unit 43, as described above, fishing line data of No. 4 400m and No. 5 350m are stored in a predetermined area. Specifically, the slope A, the intercept Bπ, the total number of revolutions c, and the data of the 0 set number of revolutions are stored in advance. When the thickness (number) of the fishing line is determined in the designated mode, these stored data are set in the water depth display area, and based on the set data, the line length is obtained as LN and the water depth is displayed. Is done.
[0047]
  Next, specific control processing performed by the reel control unit 30 will be described with reference to the control flowchart of FIG.
[0048]
  When the electric reel is connected to the external power source PS via the power cord 18, initialization is performed in step S1. In this initial setting, the count value of the spool counter 42 is reset, various variables and flags are reset, and the water depth display mode is set to the mode from the top.
Next, in step S2, display processing is performed. In the display process, various display processes such as water depth display are performed. Here, in the mode from the top, the water surface reference water depth is displayed in the water depth display area 5a. When the bottom position is set by the bottom memo key SM, the bottom position is displayed in the bottom water depth display area 5b.
[0049]
  In step S3, it is determined whether any key of the operation key unit 6 is pressed. In step S4, it is determined whether or not the spool 10 is rotating. This determination is made based on the output of the spool sensor 41. In step S5, it is determined whether any other command or input has been made.
[0050]
  If a key is input, the process proceeds from step S3 to step S6 to execute a key input process. If the rotation of the spool 10 is detected, the process proceeds from step S4 to step S7. In step S7, each operation mode process is executed.
If any other command or input is made, the process proceeds from step S5 to step S8 to execute another process.
[0051]
  In the key input process of step S6, it is determined whether or not the bobbin winding mode is set in step S11 of FIG. This determination is made based on whether or not the mode key MD is pressed. In step S12, it is determined whether or not the motor key PW has been pressed. In step S13, it is determined whether or not the upper switch of the shift key SK is pressed. In step S14, it is determined whether or not the lower switch of the shift key SK is pressed. In step S15, it is determined whether another key has been operated. In addition to the bottom memo key SM, the other key operations include operations of each key for a predetermined time or more.
[0052]
  When the mode key MD is pressed, the process proceeds from step S11 to step S16. In step S16, the bobbin winding mode is executed. As described above, the bobbin winding mode is the learning mode, the designation mode, the lower winding mode, the correction mode, and the input mode.
[0053]
  When the motor key PW is pressed, the process proceeds from step S12 to step S17. In step S17, motor control processing is executed. In this motor control process, when the motor 12 is not rotating, when the motor key PW is pressed, the motor 12 is turned on, and the duty ratio is gradually increased by the ON time of the motor key PW to increase the rotation of the motor 12. When the motor 12 is rotating, the motor 12 is turned off. When the motor key PW is released during the rotation of the motor 12, the motor key PW maintains its rotation. The same applies to the shift key SK.
[0054]
  When the upper switch of the shift key SK is pressed, the process proceeds from step S13 to step S18. In step S18, the duty ratio is gradually increased by the ON time to increase the rotation of the motor 12. When the lower switch of the shift key SK is pressed, the process proceeds from step S14 to step S19. In step S19, the duty ratio is gradually reduced by the ON time to reduce the rotation of the motor 12.
[0055]
  When another key input is made, the process proceeds from step S15 to step S20, and another key process corresponding to the operated key input such as setting the bottom shelf value at the current depth is performed.
[0056]
  In the bobbin winding mode processing in step S16, it is determined whether any of the “learning”, “designation”, “second volume”, “correction”, and “input” bobbin winding modes is designated in steps S21 to S25 in FIG.
When the learning mode is determined, the process proceeds from step S21 to step S33 in FIG. In step S33, it is determined whether or not the yarn winding onto the spool 10 has been started. This determination is made by detecting that the spool 10 has started rotating by the spool sensor 41. In step S34, it is determined whether the yarn winding has been completed. This determination is made based on whether or not a predetermined key operation (for example, an operation for a predetermined time or more of the bottom memo key SM) has been performed. After the winding of the line is completed, for example, a 10 m fishing line is fed out to learn the relationship between the number of rotations of the spool and the thread length per one rotation of the spool. In step S35, it is determined whether or not the 10m feeding has been completed. To do. This determination is also made based on whether or not a predetermined key operation has been performed. In addition, when different coloring is made, for example, every 10 m like a fishing line made of polyethylene multifilament material, the above-described feeding operation can be performed. However, when coloring is not made like a fishing line made of nylon monofilament material, a learning process may be performed by tying a 10 m fishing line to the tip and winding the 10 m fishing line. If the feeding has not ended, the process returns to step S33.
[0057]
  When the yarn winding is started, the process proceeds from step S33 to step S36. In step S36, the spool rotational speed X is increased according to the value of the spool counter 42. For example, when the spool sensor 41 outputs 10 pulses per rotation of the spool and the spool counter 42 increases by 10 per rotation of the spool, when the spool counter 42 increases by 10, the spool rotation number X is increased by 1.
[0058]
  When the yarn winding is completed and the rotation of the spool 10 is stopped, the process proceeds from step S34 to step S37. In step S37, the spool rotational speed X when winding is completed is set to the total rotational speed c. In step S38, the spool rotational speed X is decreased in accordance with the fishing line feed. Similarly to step S36, for example, when the spool counter 42 is decremented by 10, the spool rotational speed X is decreased by one.
When the yarn feeding is completed, the process proceeds from step S35 to step S39. In step S39, the spool rotational speed X reduced by the feeding is subtracted from the total spool rotational speed c, and the subtraction value is set to the feeding rotational speed d. This delivery speed d is the number of revolutions of the spool 10 when the 10m fishing line is delivered. In step S40, the spool diameter Bπ and the feeding length S are read from the storage unit 43. These two data are written in the storage unit 43 in advance.
[0059]
  In step S41, the inclination A of the approximate primary line is obtained from the obtained four data c, d, Bπ, S by the above equation (6), and the approximate primary line is calculated. As a result, the correlation between the spool one rotation length Y and the spool rotation speed X over the entire length of the fishing line with an unknown diameter and length is determined.
[0060]
  In step S42, the obtained linear straight line is integrated at the time of the total number of rotations c, and the yarn length LN from the beginning of winding to the end of winding is calculated. Then, the yarn length LN is set to zero water depth. In step S43, the total rotational speed c, the intercept Bπ, the obtained inclination A, and the yarn length LN are stored in the water depth display area of the storage unit 43. When these processes are completed, the process returns to the key input routine.
If it is determined that the designated mode is selected, the process proceeds from step S22 to step S26. In the designation mode, No. 4 or No. 5 is selected by a predetermined key operation. In step S26, it is determined whether or not No. 4 fishing line has been selected. When the No. 4 fishing line is selected, the process proceeds to step S27, where the data stored in the predetermined area of the storage unit 43 is read and set in the water depth display area of the storage unit 43. If the No. 4 fishing line is not selected, it can be determined that the No. 5 fishing line has been selected, so the process proceeds to Step S28 and the No. 5 data is set.
When the No. 5 fishing line is selected in this designated mode, when the bobbin auxiliary tool 50 is mounted on the spool 10, the water depth display data can be obtained without learning by simply winding the No. 5 fishing line 300m around the bobbin auxiliary tool 50. Is set.
[0061]
  If it is determined that the lower volume mode is selected, the process proceeds from step S23 to step S29. In step S29, the value of the intercept Bπ is changed to B1π. The bobbin diameter B1 is marked in a ring shape on the flange portion 10b of the spool 10 as shown in FIG. When the lower spool is wound up to the bobbin diameter B1, it is not necessary to wind the fishing line so thin even if the fishing line is thin. That is, in the lower winding mode, the linear straight line is calculated from the segment B1 having a diameter larger than that of the bobbin trunk 10a, which is convenient for winding a thin fishing line having an unknown thickness or length for a short length.
[0062]
  If it is determined that the correction mode is selected, the process proceeds from step S24 to step S37, the spool rotational speed X at that time is set to the total rotational speed c, and the processes after step S38 are executed. As a result, the above-described processing is executed, and even if the previously learned correlation is shifted due to the action of tension or the like, the inclination of the primary line can be corrected by learning only the final portion without performing learning over the entire fishing line.
[0063]
  If the input mode is determined, the process proceeds to step S30. In step S30, an edit process is performed on the yarn feed length (10 m) and the total number of rotations of the spool.
In each operation mode process in step S7, it is determined in step S51 in FIG. 11 whether or not the rotation direction of the spool 10 is the yarn feeding direction. This determination is made based on which one of the reed switches 41a and 41b of the spool sensor 41 has issued a pulse first. If it is determined that the rotation direction of the spool 10 is the yarn feeding direction, the process proceeds from step S51 to step S52. In step S52, the spool rotational speed X is decreased by one. This step is the same as step S38 in FIG. In step S53, every time it decreases, the data stored in the water depth display area of the storage unit 43 is read, and the current yarn length LN is calculated from the spool rotation speed X by integration processing to calculate the water depth LX. This water depth is displayed in the display process of step S2. In step S53, it is determined whether the obtained water depth LX matches the bottom position, that is, whether the device has reached the bottom. As described above, the bottom position is set in the storage unit 43 by pressing the bottom memo key SM when the device reaches the bottom. In step S54, it is determined whether the mode is another mode. If it is not in another mode, each operation mode process is terminated and the process returns to the main routine.
[0064]
  When the water depth matches the bottom position, the process proceeds from step S53 to step S55, and the buzzer 40 is sounded to notify that the device has reached the bottom. In the case of another mode, the process proceeds from step S54 to step S56, and the designated other mode is executed.
[0065]
  When the rotation of the spool 10 is determined to be the yarn winding direction, the process proceeds from step S51 to step S57. In step S57, the spool speed is increased by one. In step S58, every time it increases, the data stored in the water depth display area of the storage unit 43 is read out, and the current yarn length LN is calculated from the spool rotation speed X by integration processing, and the water depth LX is calculated. This water depth is displayed in the display process of step S2. In step S59, it is determined whether the water depth matches the boat edge stop position. If it has not been wound up to the ship edge stop position, it returns to the main routine. When the ship edge stop position is reached, the process proceeds from step S59 to step S60. In step S60, the buzzer 40 is sounded to notify that the device is on the shore. In step S61, the motor 12 is turned off. As a result, the fish is arranged at a position where it can be easily taken when the fish is caught. This ship edge stop position is set, for example, when the spool 10 is stopped for a predetermined time or less within a water depth of 6 m.
[0066]
  Here, since learning for correcting the relationship between the spool speed of the unknown fishing line and the thread length is performed only with a short thread length of the substantially final winding portion of the fishing line, without attaching a thread length detector, Yarn length can be measured. In addition, even if the tension is applied to the fishing line and the display deviates from the actual water depth, the displayed water depth can be corrected to a correct value by a simple calculation. If the No. 5 fishing line is wound in the designated mode using the bobbin auxiliary tool 50, for example, the spool 10 can be reliably wound up to the spoolable diameter of the spool 10 and accurate water depth display data can be obtained without learning. It is done.
[0067]
  <First Embodiment>
  As shown in FIG. 12, the bobbin auxiliary tool 60 may be composed of a plurality of cylindrical bodies having different diameters. This bobbin auxiliary tool 60 has first, second and third bobbin bodies 61, 62, 63 having different diameters. Each bobbin 61-63 is a two-divided cylindrical body having semicircular half-cylinders 61a-63a, 61b-63b. The first bobbin 61 is a cylindrical body having the smallest diameter and can be directly mounted on the spool 10. The second bobbin 62 is a cylindrical body that can be mounted on the outer peripheral surface of the first bobbin. The third bobbin 63 is a bobbin that can be mounted on the outer peripheral surface of the second bobbin 62. Concave and convex fitting portions 61c to 63c and 61d to 63d are formed in the split portions of the half cylinders 61a to 63a and 61b to 63b, and the half cylinders 61a to 63a and 61b to 63b are positioned in the radial direction. It is configured to be.
[0068]
  Here, for example, it is assumed that the spool 10 can wind No. 4 fishing line 400 m, No. 5 350 m, No. 6 330 m, No. 8 250 m. In this case, the volume and shape of the first bobbin 61 are formed to have substantially the same volume and shape as when No. 5 fishing line is wound around the spool 10 by 50 m. The volume and shape of the cylindrical body when the second bobbin 62 is attached to the first bobbin 61 are formed so as to have the same volume and shape as when the No. 6 fishing line is wound around the spool 10 for 30 m. Yes. Further, the volume and shape of the cylindrical body when the third bobbin 63 is mounted thereon are formed to have the same volume and shape as when No. 8 fishing line is wound around the spool 10 by 50 m. Here, when a fishing line other than No. 4 is attached to the spool 10 and the fishing line is directly wound around the bobbin trunk 10a, the No. 5 is 50 m, No. 6 is 30 m, and No. 8 is 50 m. You must purchase extra fishing line sold in units and cut it before use. However, when the above-described bobbin auxiliary tool 60 is used, the fishing line can be wound in units of 100 m up to the bobbin winding diameter, so there is no need to purchase extra fishing line.
[0069]
  In addition, if the electric reel is used, in the case of a fishing line whose number is set in the designated mode (for example, No. 5), the data for displaying the water depth can be set only by winding the spool 10.

This thread-like body has a length and the same volume and shape as when a fishing line having a maximum length of 8 is wound around a 50 m spool, for example. In addition, the thread body can be understood in order of thickness and length so as to be able to cope with the case where fractions such as No. 5 50 m, No. 6 30 m, No. 8 50 m, etc. appear as in the spool shown in (a) above. Two marks 70a and 70b are attached. This makes it easy to know that No. 5 50m when wound to mark 70a, No. 6 30m when wound further to mark 70b, and No. 8 50m when wound to the end, respectively. Even if troublesome preparation work is not performed, it can be easily wound so as not to give a fraction.
