In the other setting process of S103, the display mode is set to display the opening screen in the subsequent display process (see FIG. 12). Further, the correction count K of the device water depth data D1 is set to 1.

  In step S <b> 2, it is determined whether or not fish finder data (specifically, echo data D <b> 2 and D <b> 3 on the seabed depth and shelf position of the fishing ground) from the fish finder 120 is received. If the fish finder data cannot be received, it waits until it can be received. When the fish finder data is received, the process proceeds to step S 3, where the received fish finder data D 1 to D 3 are captured and stored in the storage unit 61. In step S4, it is determined whether or not the electric reel 100 is connected. If the electric reel 100 is not connected, the process proceeds to step S5, and the flag NC indicating that the electric reel 100 is not connected is turned on. When the electric reel 100 is connected, the process proceeds from step S4 to step S6 and the flag NC is turned off. In step S7, the device water depth data D1 transmitted from the electric reel 100 is taken.

In this display processing, in addition to the opening screen, the screen is switched to a fish finder screen that displays water depth data obtained from the electric reel 100 and fish finder data from the fish finder 120, and a menu screen that performs various settings. In step S9, it is determined whether or not the operation key unit 62 has been operated. In step S10, it is determined whether or not there is a transmission request for transmission to the electric reel 100. In step S10 and step S4, for example, it is determined whether or not another process such as a maintenance process using a hidden command has been selected. If the determination is “No”, the process returns to step S2. When the operation key unit 62 is operated, the process proceeds from step S9 to step S12, and a key input process described later is performed. When there is a transmission request, the process proceeds from step S10 to step S13, and setting data set by menu processing described later is transmitted to the electric reel 100 via the wireless communication unit 64. When another process is selected, the process proceeds from step S11 to step S14, the designated other process is executed, and the process returns to step S2.

In the backlight display process, it is determined in step S71 in FIG. 15 whether an external power source such as a storage battery is connected or an internal power source such as a dry battery is connected. If it is determined in S71 that an external power source such as a storage battery is connected, the process proceeds to S76, and it is determined whether the amount of light detected by the optical sensor 65 is 15 lux or more. If it is determined in S76 that the amount of light detected by the optical sensor 65 is 15 lux or more, the process proceeds to S78, where the luminance of the backlight 51b is set to 100%, which is the maximum luminance. If it is determined in S76 that the amount of light detected by the optical sensor 65 is less than 15 lux, the process proceeds to S77, and the luminance of the backlight 51b is set to be 70% of the maximum luminance. When the brightness settings of S77 and S78 are performed, the process proceeds to S74, the backlight 51b is displayed so as to have the brightness set in S77 and S78, and the process returns to the display processing subroutine shown in FIG.

  If it is determined in step S71 in FIG. 15 that an internal power source such as a dry battery is connected, the process proceeds to S72, and it is determined whether the light amount detected by the optical sensor 65 is 15 lux or more. If it is determined in S72 that the amount of light detected by the optical sensor 65 is 15 lux or more, the process proceeds to S75, where the brightness of the backlight 51b is set to 70% of the maximum brightness. If it is determined in S72 that the amount of light detected by the optical sensor 65 is less than 15 lux, the process proceeds to S73, where the brightness of the backlight 51b is set to 50% of the maximum brightness. When the brightness settings in S73 and S75 are performed, the process proceeds to S74, the backlight 51b is displayed so as to have the brightness set in S73 and S75, and the process returns to the display processing subroutine shown in FIG.

  When the backlight display process in step S21 in FIG. 13 is performed, it is determined in step S22 in FIG. 13 whether the opening screen has been set. Next, it is determined in step S22 in FIG. 13 whether or not the opening screen has been set. This opening screen is displayed only once when the power cord 13 is connected and the power is turned on. In step S23, it is determined whether or not a menu screen has been set by the screen switching button 52. In step S24, it is determined whether or not the fish finder screen has been selected by the screen switching button 52. If the fish finder screen has not been set, the process returns to the main routine shown in FIG.

  When the opening screen is set, the process proceeds from step S22 to step S25, and the opening screen is displayed. When the menu screen is set, the process proceeds from step S23 to step S26. In step S26, the menu screen shown in FIGS. In this menu screen, the reception state 71 of the radio wave output from the fish finder 120 is displayed on the upper left of the screen. The radio wave reception state 71 is displayed with an antenna mark and three lines, and this display is displayed in all display modes. On the right side, a clock display 72 representing the current time is displayed with digital numbers. Further, a remaining amount display 73 of an internal power source such as a dry battery is displayed on the upper right side of the screen as a figure simulating a battery. When the remaining amount of the internal power source such as a dry battery is maximum, the remaining amount display 73 is displayed by filling three rectangular portions, and as the remaining amount decreases, two rectangular portions, one rectangular portion, The number of filled parts, such as individual rectangular parts, is reduced. Below the reception state 71 and the clock display 72, setting items 77 for various modes of the fishing information display device 60 (specifically, as shown in FIGS. Correction, bottom line, background color and blur locus) and setting contents 78 (OFF, ON) thereof are hierarchically displayed as menus, and further, setting items 77 (specifically, FIG. 18) of various modes of the electric reel 100. As shown in Fig. 4, the menu is hierarchically displayed for shelf stop, automatic scouring, thread feeding, upper bottom switching, in-process collection, number of windings, winding time, clock, demo screen) and setting contents 78 (OFF, ON). Has been. When the setting contents of the electric reel 100 are set in the electric reel 100, the data is received and the contents are reflected in the setting contents of the menu screen. These setting items and setting contents are selected by the cursor button 53, and the setting contents are confirmed by the decision button 54. Here, the in-process collection shown in FIG. 18 is a function of collecting the apparatus, that is, displaying in seconds how long it takes to stop the ship's edge. The number of hoisting is a function for displaying the number of times of hoisting today, that is, the number of times of hoisting until the ship edge is stopped. The winding time is a function for displaying the total time during which the motor 4 is driven. The clock is a function for setting a time to be displayed on the clock display 72 representing the current time. Here, the position correction shown in FIGS. 9 and 10 is set when it is desired to correct the water depth data of the device obtained from the electric reel. Further, the blur locus is set when it is desired to display a time-series change locus of the water depth data of the device.

  When the fish finder screen is set, the process proceeds from step S24 to step S27. In step S27, it is determined whether or not the electric reel 100 is connected by the flag NC. When the electric reel 100 is connected, the process proceeds from step S27 to step S28. If the electric reel 100 is not connected, the process proceeds from step S27 to step S36. In step S37, the reception state 71 of the radio wave from the fish detector 120 is displayed with the antenna mark and the three lines in the same manner as the menu screen. Display in the upper left.

  In step S28 of FIG. 13, a fish finder screen as shown in FIG. 11 is displayed. In step S28, the scale SC of the water depth is displayed at the right end of the screen, and a value (K × D1) obtained by multiplying the water depth data D1 of the device obtained from the electric reel 100 by the correction coefficient K is displayed on the right side of the scale SC. For example, it is displayed at a position corresponding to the water depth with a needle figure symbolizing the mechanism. In this embodiment, since the correction coefficient is set to 1 before correction, the water depth data before correction is displayed, but before the correction is performed, the water depth data D of the device is displayed as it is, After the correction, the corrected water depth data K × D1 may be displayed.

  Also, the seabed depth data D2 and the shelf depth data D3 received from the fish detector 120 are displayed in time series in echo data images at positions corresponding to the depth on the left side of the scale SC. Further, the numerical value D2n of the seabed depth data D2 is displayed at the lower left of the screen, and the numerical value D1n of the water depth data D1 is also displayed at the upper left of the screen. Further, the value of the shelf timer (device stationary time set to automatically set the shelf position) is also displayed below the numerical value D1n. In step S29, the reception state 71 of the radio wave from the fish finder 120 is displayed on the upper left portion of the screen with the antenna mark and the three lines as in the menu screen. In step S30, it is determined whether or not the display setting of the device trajectory is on. This setting is determined by whether or not the blur locus is on. If the spot locus display is on, the process proceeds to step S31. In step S31, as shown in FIG. 12, the mechanism trajectory, which is a time-series change in the mechanism water depth data D1, is displayed in dots. In step S32, the pitch width of the pitch mode is displayed on the right side of the scale SC as indicated by hatching. This display is not displayed when the saddle mode is off. In step S33, the bottom line display process shown in FIG. 16 is performed. In step S34, enlargement / reduction display processing shown in FIG. 17 is performed. In step S35, other display is performed.

  The bottom line display process of FIG. 16 is a process of displaying the bottom line 81 that is the boundary of the bottom image 80 shown in FIG. The bottom line 81 is water bottom information indicating the bottom portion where the reflected wave response of the fish finder 120 is strongest, and excludes information on algae (eg, expressed in red or yellow) where the reflected wave response is weak. It highlights the true bottom. The bottom line 81 is a line in which numerical information indicating the bottom position is graphed. For example, the bottom line 81 is displayed in a bold line (wide display), or the color of the line in which the water bottom information is graphed is changed to another image (red or yellow) or background. It is highlighted by making it a color different from the color (black or blue), for example, white. Here, first, in S81 of FIG. 16, it is determined whether or not the mode for displaying the bottom line 81 is set. Specifically, in the mode setting screen shown in FIG. 9, when the setting content 78 of the bottom line setting item 77 of the fishing information display device 60 is “ON”, the bottom line 81 is displayed in S81. It is judged that If it is determined in S81 that the mode is for displaying the bottom line 81, the flow proceeds to S82, and the bottom information, that is, the position for drawing the line is read. In S83, the width of the line is set to, for example, bold line display, and in S84, the color of the line is set to white when the background color is black or blue, for example. In S84, if the background color is white, the line color is set to black. In S85, a wide white line is displayed as the bottom line 81 at the position read in S83 (see FIG. 4). On the other hand, in the mode setting screen shown in FIG. 10, when the setting content 78 of the bottom line setting item 77 of the fishing information display device 60 is “OFF”, the mode is not the mode for displaying the bottom line 81 in S81. And only the bottom image 80 shown in FIG. 11 is displayed.

  As shown in FIGS. 4 to 6, the enlargement / reduction display processing of FIG. 17 relates to underwater according to the number of times of pressing the upper button 53a or the lower button 53b (see FIG. 3) of the cursor button 53 of the operation key unit 62. This is processing for enlarging / reducing the fishing information on the display unit 51 with the water surface as a reference. Here, first, in S91 of FIG. 17, it is determined whether or not the upper button 53a has been pressed once. When the upper button 53a is pressed once, the process proceeds to S94 and is set to enlarge one step. Here, when the scale SC of the water depth is in the range of 0 m to 100 m on the normal screen (see FIG. 4), for example, the water depth direction is such that the water scale SC is in the range of 0 m to 90 m. Is to expand. For example, when the upper button 53a is pressed three times (three-stage expansion), the water depth scale SC is expanded from 0 m to 70 m (see FIG. 5), and when the upper button 53a is pressed five times. (5 stages of expansion), the scale SC of the water depth is expanded to a range of 0 m to 50 m (see FIG. 6). Here, for example, 10 levels of enlargement / reduction are possible. If it is determined in S91 that the upper button 53a has not been pressed once, the process proceeds to S92 to determine whether or not the lower button 53b has been pressed once. When the down button 53b is pressed once, the process proceeds to S95 and is set to be reduced by one step. If it is determined in S92 that the lower button 53b has not been pressed once, the process proceeds to S93 to determine whether the left button 53c or the right button 53d has been pressed once. When the left button 53c or the right button 53d is pressed once, the process proceeds to S96 to reset the setting enlarged or reduced so far and display the normal screen shown in FIG. In this fishing information display device 60, it is possible to switch between the enlarged display similar to the conventional one and the above-described enlarged / reduced display.

  In step S9 of FIG. 12, when any button of the operation key unit 62 is operated, the process proceeds from step S9 to step S12, and the key input process shown in FIG. 14 is executed. In the key input process, it is determined whether or not the screen switching button 52 has been operated in step S41 of FIG. In step S42, it is determined whether or not the cursor button 53 has been operated. In step S53, it is determined whether or not the enter button 54 has been operated. In step S4, it is determined whether or not the on / off button 55 has been operated. In step S45, it is determined whether or not the on / off button 56 has been operated.

  When the screen switching button 52 is operated, the process proceeds from step S41 to step S50. Although not described in step S50, when the motor 22 of the electric reel 100 is rotating, the key input of the screen switching button 52 is invalid. This is so that the screen cannot be switched during winding. In step S50, it is determined whether an opening screen is set. If the opening screen is set, the process proceeds to step S51 and the display mode is set to the menu screen. Thereby, a menu screen is displayed by the display process of step S8. When the opening screen is not set, the process proceeds to step S52 to determine whether or not the menu screen is set. If the menu screen is set, the process proceeds to step S53, and the display mode is set to the fish finder screen. Thereby, the fish finder screen is displayed in the display process of step S8. If the menu screen is not set, the display mode is set to the menu screen. When these processes are completed, the process proceeds to step S42.

  When the cursor button 53 is operated, the process proceeds from step S42 to step S55. In step S55, the cursor is moved one by one with the setting item or setting content on the menu screen according to the direction of the operated cursor.

  When the enter button 54 is operated, the process proceeds from step S43 to step S56. In step S56, it is determined whether or not it is a fish finder screen. If it is determined that the fish finder screen is displayed, the process proceeds to step S57. In step S57, it is determined whether or not position correction is set (turned on). If position correction is set, the process proceeds to step S58 to perform position correction. Here, when the enter button 54 is operated on the fish finder screen, a correction start signal is output and correction processing is performed.

  Normally, this operation is performed when the fisherman performs bottoming to lower the device to the bottom, as shown in FIG. 14, when the device water depth data D1 changes greatly from the actual seabed data D2 and the display is inconsistent. To be done. In the example shown in FIG. 14, the actual depth of the seabed is 73 meters, whereas the fishing line is unwound by 85 m when the device reaches rotation due to the influence of the ocean current or the like. When the fisherman operates the determination button 54 in such a situation, the process proceeds to step S57 via step S56, and the actual seabed water depth data D2 received at this timing is divided by the water depth data D1 to be corrected. K is calculated. This correction coefficient K is multiplied by the water depth data D1 in the display process. For example, in the example shown in FIG. 14, the correction coefficient is 73/85, and the device water depth data D1 is displayed after being multiplied by the correction coefficient K until the next correction process is performed. As a result, the graphically displayed water depth data D1 and the numerical data D1n are corrected to become corrected water depth data. When the power cord 13 is disconnected and the power is shut off, the correction coefficient is set to 1 by default. Further, such correction processing is not performed on the electric reel 100 side. This is because when the correction is performed with the electric reel 100, the boat edge stop position and the like are shifted by the correction amount when winding the fishing line. Therefore, this correction is performed only by the fishing information display device 60.

  If it is determined in step S56 that the position correction is off, the process proceeds to step S44. If it is determined that it is not the fish finder screen, the process proceeds from step S56 to step S59. In step S59, the content of the setting item selected by the cursor is determined and set in the storage unit 45. In step S60, it is determined whether or not the setting item relates to the electric reel 100, that is, whether or not transmission to the electric reel 100 is necessary. When transmission is necessary, a transmission request for transmitting the determined setting is output. Thereby, setting data is transmitted to the electric reel 100 in step S13.

  When the on / off button 55 is operated, the process proceeds from step S4 to step S62. In step S62, a transmission request for turning on / off the motor 22 with the set saddle width is output.

  When the on / off button 56 is operated, the process proceeds from step S45 to step S63. In step S63, it is determined whether or not the display unit 51 is on. If the display unit 51 is not turned on yet, the process proceeds to step S64 and the display unit 51 is turned on. When the display unit 51 is already turned on, the process proceeds to step S65 and the display unit 51 is turned off.

  In the fishing information display control unit 60, the brightness of the display unit 51 is changed according to the brightness of the ambient light detected by the optical sensor 65. Therefore, when the ambient brightness changes, the fishing information display control unit 60 automatically The brightness of the display unit 51 is changed. Here, since the brightness of the display unit 51 is automatically changed, it is not necessary for the angler to operate the brightness adjustment button as in the prior art. Therefore, the visibility of the display unit 51 can be maintained high without bothering the angler. Furthermore, since the bottom information indicating the bottom portion where the reaction of the reflected wave of the fish finder 120 is the strongest is highlighted as the bottom line 81, the visibility of the bottom information can be increased.
