This invention relates to a fishing line winding length management device for a fishing reel, a fishing reel, a fishing line winding length management method for a fishing reel, and a fishing line winding length management program. Conventional fishing reels are known to calculate the length of fishing line wound on the reel based on a formula relating the diameter of the fishing line and the number of rotations of the reel (see, for example, Patent Document 1). [Prior Art Documents] [Patent Documents] [Patent Document 1] Japanese Patent Application Publication No. 6-141742 [The problem the invention aims to solve] "High breakage" refers to a situation where the fishing line breaks midway through the fishing rig after it has been cast into the water. When a high breakage occurs, the length of line wound on the reel will decrease until the breakage occurs. It is best to inform the user (angler) of the remaining line length as the reduced line length is handled. The purpose of this invention is to appropriately inform the user of the length of the fishing line wound on the reel. [Technical means to solve the problem] One aspect of the present invention that solves the above-mentioned problems is a fishing line winding length management device for a fishing reel, comprising: a memory unit that stores fishing line winding length information that displays the length of the fishing line wound on the reel; a calculation unit that calculates and displays the length of the fishing line ejected from the reel based on the rotation of the reel detected by a rotation detection unit for detecting the rotation of the reel; a reset unit that resets the ejection length information calculated by the calculation unit; an update unit that updates the fishing line winding length information stored in the memory unit according to the reset performed by the reset unit and the ejection length information before the reset; and a display control unit that displays the fishing line winding length information updated by the update unit according to the reset of the ejection length information performed by the reset unit. One aspect of the present invention is a fishing reel that includes the aforementioned fishing line winding length management device. One aspect of the present invention is a method for managing the length of fishing line wound on a fishing reel, comprising: a calculation step, which calculates, based on the rotation of the reel detected by a rotation detection unit that detects the rotation of the reel, the length of the fishing line wound from the reel and displayed thereon; a reset step, which resets the length of the fishing line wound on the reel calculated by the calculation step; an update step, which updates the length of the fishing line wound on the reel in a memory unit for displaying the length of the fishing line wound on the reel, based on the length of the fishing line wound on the reel before the reset, in accordance with the reset performed by the reset step; and a display control step, which displays the length of the fishing line wound on the reel updated by the update step, in accordance with the reset performed by the reset step.

[Effects of the Invention] According to the present invention, it is possible to obtain the effect of being able to appropriately inform the user of the length of the fishing line wound on the reel. <First Embodiment> Hereinafter, with reference to the drawings, the electric fishing reel 1 used as a fishing line winding length management device according to this embodiment will be described. Furthermore, in the following description, the electric fishing reel 1 is an example of a double-bearing reel. Also, in Figures 1 and 2, in order to make each component a visually confirmable size, there are cases where the proportions of each component can be appropriately changed as needed. [Example of the construction of an electric fishing reel] Figures 1 and 2 show examples of the appearance of the electric fishing reel 1 according to this embodiment. The electric fishing reel 1 of this embodiment mainly includes: a reel body 2 that can be mounted on a fishing rod (not shown), an operating lever 3 that is rotatably mounted on the reel body 2 around a handle axis O1, a spool 4 that is rotatable around the reel body 2 around a spool axis O2 parallel to the handle axis O1 and can wind up fishing line (not shown), and a clutch mechanism 6 having a clutch operating lever 5. Furthermore, the electric fishing reel 1 of this embodiment includes a motor (not shown) that drives the spool 4 to rotate. The motor is disposed within a motor housing 7 located in the reel body 2. The electric fishing reel 1 also includes a motor bracket 9 that secures the motor within the reel body 2. The motor bracket 9 is assembled to the reel body 2 by plugging the motor housing 7 inside. In this embodiment, the handle axis O1 and the drum axis O2 are arranged parallel to each other, and the direction along these axes is defined as the left-right direction L1. The direction perpendicular to the left-right direction L1 and along the direction in which the fishing line wound on the drum 4 is ejected is defined as the front-back direction L2. Further, in the front-back direction L2, the direction in which the fishing line is ejected from the drum 4 is defined as the front, and the opposite direction is defined as the rear, and the left and right are defined by the viewpoint from the rear side (user side) of the electric fishing reel 1. Therefore, FIG1 is a perspective view of the electric fishing reel 1 viewed from an obliquely upper, left rear perspective. The reel body 2 includes: a body frame 10, side covers 20 covering the left and right sides of the body frame 10, and a front cover 30 covering the front side of the body frame 10. The main body frame 10 is a molded part made of, for example, synthetic resin or metal (e.g., aluminum casting). The main body frame 10 includes: a first side wall 11 and a second side wall 12 arranged facing each other in the left-right direction L1 on both sides of the roll 4, and a connecting member 13 that connects the first side wall 11 and the second side wall 12 to each other in the left-right direction L1. The first side wall 11 is the left side wall located on the left side (LH) of the reel 4. The second side wall 12 is the right side wall located on the right side (RH) of the reel 4. The operating lever 3 is located further to the right (RH) than the second side wall 12 and is mounted to the main body frame 10 using the second side wall 12. Therefore, the electric fishing reel 1 of this embodiment is a right-side operating lever type reel. Furthermore, the second side wall 12 protrudes downwards more than the first side wall 11 because of the connector portion 23 and the like. The connecting member 13 is a plate-shaped component that connects the first sidewall 11 and the second sidewall 12 to each other in the left-right direction L1, and is disposed near the lower part of the first sidewall 11. Thus, the first sidewall 11 and the second sidewall 12 are strongly connected through the connecting member 13. Furthermore, the mounting plate 14 for attaching the electric fishing reel 1 to the fishing rod is formed in the central portion of the connecting member 13 in the left-right direction L1, extending along the front-back direction L2. In the main body frame 10 with the structure described above, at least the following are arranged between the first side wall 11 and the second side wall 12: a motor housing cylinder 7, a drum 4, and a clutch operating lever 5, which house the motor. The reel 4 is disposed between the first side wall 11 and the second side wall 12 and is located further rearward than the handle axis O1. The motor housing 7 is disposed between the first side wall 11 and the second side wall 12 and is located further forward than the handle axis O1. Therefore, the electric fishing reel 1 of this embodiment is an external motor type in which the motor is disposed further forward than the reel 4. The side cover 20 includes: a first side cover 21 which is assembled to the main body frame 10 and covers the first side wall 11 from the left side (LH) where the opening of the motor housing 7 is formed, and a second side cover 22 which is assembled to the main body frame 10 and covers the second side wall 12 from the right side (RH). The first side cover 21 is formed by expanding to the left (LH) and is, for example, screwed to the first side wall 11. The second side cover 22 is formed by expanding to the right (RH) and is, for example, screwed to the second side wall 12. The power cord coil for supplying power from an external power source or the connector portion 23 for connecting a portable battery is installed in the lower front part of the second side cover 22 with the connector end (not shown) facing downwards. As shown in the figures, the connector end is protected by a protective cap 24. The front cover 30 is assembled to the main body frame 10 from the front, covering the front portion of the main body frame 10. Specifically, the front cover 30 is assembled to the front portion of the first side wall 11 and the second side wall 12 from the front, covering the motor housing 7, and is, for example, screwed to the first side wall 11 and the second side wall 12. Furthermore, the front cover 30 is installed so as not to cover the moving area of ​​the uniform winding 55 described later. In the upper part of the main body frame 10 with the structure described above, a counter housing 40 is provided. The counter housing 40 is fixed to the upper part of the first side wall 11 and the upper part of the second side wall 12 by means of, for example, screws, while it is disposed between the first side wall 11 and the second side wall 12. On the top of the main body of the meter housing 40 is the display control panel 41. The display control panel 41 is a part used by the user of the electric fishing reel 1 to display information and allow the user to operate buttons and switches. The operating lever 3 is used for manually winding the fishing line. The operating lever 3 is located further to the right (RH) than the main frame 10 and the first side cover 21. The operating lever 3 includes: a handle shaft 50 rotatable around the handle axis O1; an operating lever arm 51 non-rotatable on the handle shaft 50; and an operating lever knob 52 rotatable around an axis parallel to the handle axis O1 at the end of the operating lever arm 51. Between the operating lever arm 51 and the first side cover 21 is a traction member 53 (star-shaped traction device) coaxial with the handle axis O1. This traction member 53 applies arbitrary traction force to the spool 4 during winding to brake the rotation of the spool 4, thus helping to prevent the fishing line from being cut. The rotational torque from the operating lever 3, given this structure, can be directly transmitted to the drum 4 via a rotation transmission mechanism (not shown) when the clutch mechanism 6 is in the clutch engaged (ON) state. Furthermore, although this embodiment illustrates a single-lever type with an operating lever knob 52 mounted only at one end of the operating lever arm 51, it is not limited to this. For example, a dual-lever type fishing electric reel 1 with the operating lever knob 52 mounted at both ends of the operating lever arm 51 and the central portion of the operating lever arm 51 non-rotatably mounted to the handle shaft portion 50 is also acceptable. The drum 4 is disposed between the first side wall 11 and the second side wall 12 in the frame body, and is rotatably supported on the first side wall 11 and the second side wall 12 via bearings (not shown) around the drum axis O2. The drum 4 includes: a drum rotation shaft (not shown) that rotates around the drum axis O2, and a winding body 4a that is coaxially disposed with the drum rotation shaft and rotates in conjunction with the drum rotation shaft. The clutch mechanism 6 can be switched between two states by operating the clutch operating lever 5: a clutch engaged (ON) state, in which the rotational torque from the operating lever 3 is transmitted to the drum 4 via a rotational transmission mechanism (not shown), and a clutch disengaged (OFF) state, in which the torque is not transmitted. Therefore, in the clutch engaged (ON) state, rotating the operating lever 3 transmits the rotational torque generated by this rotation to the drum 4, allowing the drum 4 to rotate around its axis O2. This enables manual winding. Conversely, when the clutch mechanism 6 is in the clutch disengaged (OFF) state, the rotational torque generated by rotating the operating lever 3 is not transmitted to the drum 4, allowing the drum 4 to rotate freely (drum free state). The clutch operating lever 5 is a switching operating lever used to switch the clutch mechanism 6 to the clutch engaged (ON) state and the clutch disengaged (OFF) state. The clutch operating lever 5 is located further rearward than the drum 4, between the first side wall 11 and the second side wall 12, and can move up and down by swinging around the drum axis O2. Furthermore, the rotation transmission mechanism transmits rotational torque to the drum 4 while increasing the rotational speed of the operating lever 3. Further, when the clutch mechanism 6 is in the clutch engaged (ON) state, the rotation transmission mechanism transmits not only the rotational torque generated by the rotation of the operating lever 3 to the drum 4, but also to the uniform winding mechanism (not shown). The uniform winding mechanism is used to evenly wind the fishing line onto the drum 4. Furthermore, the rotary transmission mechanism, when the clutch mechanism 6 is in the clutch engaged (ON) state and the motor is driven, transmits the rotational torque accompanying the motor's drive to the drum 4. This enables automatic winding operations. Also, the rotary transmission mechanism transmits the rotational torque to the drum 4 while the motor's rotation is being reduced in speed. [Regarding Zeroing Setting Processing and Fishing Line Reel Length Display] The electric fishing reel 1 of this embodiment can calculate and remember the length of the fishing line wound on the reel 4 (fishing line reel length). In actual fishing, when the fishing rig, for example, is in the water at the tip of the fishing line, a "high break" can occur where the fishing line breaks off midway outside the rig. When a high break occurs, a portion of the fishing line extending beyond the point of breakage is lost from the line being ejected from the reel 4. Therefore, if a high break occurs, the fishing line reel length will be shortened due to the lost length of fishing line. If the reduction in fishing line reel length caused by a high break is significant, there is a possibility that the fishing rig may not be able to reach the target water depth (seabed) depending on the length of the reel after the high break. Therefore, it is preferable for the user to immediately grasp the length of the remaining portion of fishing line wound on the reel after the high break. Here, the electric fishing reel 1 of this embodiment can be used to cut the line at a high speed, and as explained below, the length of the fishing line wound after the high speed is cut is reported to the user. In actual fishing, if a break occurs, the user reels the fishing line onto the reel 4 until the line is extended to a length sufficient to attach the fishing rig to the end of the line after the break. The user then reattaches the fishing rig to the end of the line. During this reattachment, the water depth is measured by the fishing reel 1 and displayed on the display. As mentioned above, because the user has reeled the line to a certain extent, the displayed depth is shallower or equivalent to the depth measured at the time of the break. Here, the user performs a zeroing operation, for example, with the fishing rig at the water's surface. The zeroing operation is an instruction to perform a zeroing process. Corresponding to the zeroing operation, the fishing reel 1 performs a zeroing process, resetting the current reel rotation count to zero. When the reel rotation count is zero, the displayed water depth is zero. The water depth is measured as the reel rotation count increases (deepers) from zero as the fishing line is extended. Furthermore, in this embodiment, the water depth measured is taken as the length of the fishing line ejected from the reel 4 (ejection length). By performing a zeroing operation in response to the high cut, the water depth can be reset to suit the ejection position of the fishing rig after the high cut. The zeroing setting process corresponding to the zeroing setting operation in this embodiment can selectively perform two different processes: high-impact correction and tension correction. The high-impact correction zeroing setting process addresses the high-impact situation described above. The tension correction zeroing setting process addresses errors caused by tension acting on the fishing line, such as when the water depth is not zero when the fishing rig is on the surface. The content of the zeroing setting processes performed for high-impact correction and tension correction are different. Therefore, it can be seen that different operations can be used to indicate high-impact correction and tension correction. However, since the point of zeroing setting is the same for the user, a common zeroing setting operation can be performed. The electric fishing reel 1 of this embodiment performs one of the high-impact correction or tension correction zeroing setting processes according to the measured water depth value when the zeroing setting operation is performed. Specifically, the electric fishing reel 1 performs high-impact correction when the measured water depth value during the zeroing setting operation is greater than, for example, 10 meters, and performs tension correction when it is less than 10 meters. Furthermore, due to the high break, the length of fishing line wound on the reel is reduced, which is the length of fishing line lost before the high break. In this embodiment, the electric fishing reel 1 performs a zeroing operation as described above in the process corresponding to the user's response to the high break, and performs a zeroing setting process to correct the high break, recalculating the length of fishing line wound on the reel 4. In this embodiment, the electric fishing reel 1 pre-memorizes the length of fishing line wound. The electric fishing reel 1 calculates the length of fishing line ejected by calculating the number of reel rotations and displays the water depth corresponding to the calculated ejection length. The electric fishing reel 1 recalculates the length of fishing line wound after the high break by subtracting the ejection length at the time point before the zeroing setting process reset from the previously memorized length of fishing line wound. The electric fishing reel 1 updates the memorized value of the fishing line wound length to the recalculated value of the fishing line wound length. The electric fishing reel 1 displays the updated fishing line winding length on the display unit 102 as described above. That is, the electric fishing reel 1 informs the user of the fishing line winding length after shortening it to the corresponding height. Figure 3 shows an example of the fishing line reel length displayed on the display unit 102. In the same figure, the fishing line reel length is displayed on the display unit 102 via a pop-up screen PU. In the pop-up screen PU of the same figure, the recalculated reel length (fishing line reel length) is displayed as 300 meters. This display in the same figure is immediately shown to the user on the display unit 102 in response to a zeroing operation performed due to a high fault. That is, the user can immediately confirm the fishing line reel length that has shortened due to the high fault at the time of the zeroing operation. In other words, in this embodiment, the user is informed of the fishing line reel length changed due to the high fault at an appropriate time. The pop-up screen PU can be cleared after a predetermined time, such as a few seconds. Alternatively, the pop-up screen PU can be cleared after, for example, a predetermined confirmation operation performed by the user. In this case, the confirmation operation can be performed on the specified button. When the display surface of the display unit 102 functions as an operation panel such as a touch panel or a contactless operation panel, the specified operation can be performed on the display surface of the display unit 102 (such as clicking on an area in the pop-up screen PU). For example, the fishing line reel length can be displayed as an item in the menu screen. However, in this case, the user needs to perform a series of screen operations to reach the screen displaying the fishing line reel length. In contrast, if the reel length is automatically displayed on the display unit 102 in response to the zeroing setting operation, the user does not need to perform the aforementioned series of screen operations. That is, according to this embodiment, the user can confirm the reel length after a break without frequent operation, and the fishing line reel length can be appropriately reported to the user from an operability point of view. Furthermore, in this embodiment, in addition to displaying the fishing line reel length on the pop-up screen PU, as mentioned above, the fishing line reel length can also be displayed in the menu screen displayed through user operation. The fishing line reel length displayed here becomes fishing line reel length information stored in the fishing line reel length information memory unit 141. [Example of Functional Components of an Electric Fishing Reel] Referring to Figure 4, an example of the functional components of an electric fishing reel 1 will be described. In the same figure, parts that are the same as those in Figures 1 and 2 are given the same reference numerals and their descriptions are appropriately omitted. The electric fishing reel 1 shown in the figure includes an operation unit 101, a display unit 102, a control unit 103, a memory unit 104, a motor drive circuit 105, a motor 8, a reel 4, and a rotation sensor 106. Furthermore, the communication unit 107 and the user terminal 200 connected to the communication unit 107 are omitted here because they correspond to the second embodiment. The control unit 103 performs various controls on the electric fishing reel 1. The functions of the control unit 103 are implemented by the CPU (Central Processing Unit) of the electric fishing reel 1 executing programs. The control unit 103 includes a calculation unit 131, a reset unit 132, an update unit 133, and a display control unit 134. The calculation unit 131 calculates the discharge length (discharge length information). The discharge length is the length of fishing line discharged from the spool 4. The calculation unit 131 calculates the discharge length based on the number of spool rotations detected by the rotation sensor 106. The reset unit 132 performs zero-setting processing in response to a zero-setting operation. The reset unit 132 is a functional unit that performs zero-setting processing in response to a zero-setting operation, and includes a high-displacement correction unit 1321 (an example of a first correction unit) and a tension correction unit 1322 (an example of a second correction unit). The high-displacement correction unit 1321 performs zero-setting processing for high-displacement correction. The tension correction unit 1322 performs zero-setting processing for tension correction. In the reset unit 132, the high-displacement correction unit 1321 and the tension correction unit 1322 perform a common zero-setting process, resetting the drum rotation count to zero during a zero-setting operation. Both the high-displacement correction unit 1321 and the tension correction unit 1322 reset the drum rotation count to zero, and also reset the discharge length (equivalent to water depth) calculated based on the drum rotation count to zero. The updating unit 133 updates the fishing line reel length information in response to the zeroing setting process performed by the high-speed correction unit 1321 of the reset unit 132. Specifically, the updating unit 133 performs the high-speed correction unit 1321's zeroing setting process in response to the zeroing setting operation. It subtracts the fishing line reel length currently displayed in the fishing line reel length information memory unit 141 from the output length calculated by the calculation unit 131 at the time point before the reset (output length information before the reset), and then recalculates the fishing line reel length after the high-speed setting. The updating unit 133 updates the fishing line reel length information stored in the fishing line reel length information memory unit 141 to the recalculated fishing line reel length. The display control unit 134 displays information about the fishing line reel length, which is updated by the aforementioned update unit 133, in response to the zeroing setting process performed by the high-precision correction unit 1321 of the reset unit 132. The display control unit 134 displays the recalculated and updated fishing line reel length via, for example, a pop-up screen PU as shown in Figure 3. The memory unit 104 stores various information corresponding to the electric fishing reel 1. The memory unit 104 includes a fishing line winding length information memory unit 141. The winding date and time memory unit 142, being for the third embodiment, will not be described here. The fishing line winding length information memory unit 141 stores fishing line winding length information that displays the length of the fishing line wound on the reel 4 (fishing line winding length). The fishing line winding length displayed by the fishing line winding length information stored in the fishing line winding length information memory unit 141 is updated to the fishing line winding length recalculated by the update unit 133. The motor drive circuit 105 drives the motor 8 in response to the control unit 103. The control unit 103 uses PWM control to change the load power ratio of the motor drive signal pulse width, thereby changing the rotational speed of the motor 8. The rotation sensor 106 detects the number of rotations of the drum, the rotational speed of the drum 4, etc. [Processing Step Example] Referring to the flowchart in Figure 5, an example of processing steps related to calculating the feed length is described for the fishing electric reel 1. Step S100: In the fishing electric reel 1, the calculation unit 131 determines whether the drum 4 is rotating based on the detection output of the rotation sensor 106. Step S102: When the calculation unit 131 determines that the drum 4 is rotating in step S100, it obtains the number of rotations of the drum 4 detected by the rotation sensor 106. Step S104: The calculation unit 131 calculates the feed length corresponding to the number of drum rotations obtained in step S102. The calculation unit 131 can store the feed length calculated in step S104 in a memory device such as RAM (Dynamic Random Access Memory) provided with the fishing electric reel 1. Referring to the flowchart in Figure 6, an example of the processing steps related to the zeroing setting process performed by the fishing electric reel 1 is described. Step S200: In the fishing electric reel 1, the reset unit 132 is in standby mode, waiting for a zeroing setting operation. Step S202: If a zeroing setting operation has been performed, the reset unit 132 determines whether this zeroing setting operation is performed in accordance with a high-voltage condition. As mentioned above, the reset unit 132 can determine whether this zeroing setting operation is performed in accordance with a high-voltage condition based on whether the current output length value calculated by the calculation unit 131 is greater than a specified value. Step S204: If it is determined in step S202 that this zeroing setting operation corresponds to a high fault, the high fault correction unit 1321 in the reset unit 132 performs a high fault correction zeroing setting process. The high fault correction performed by the high fault correction unit 1321 resets the number of drum rotations currently detected by the rotation sensor 106 to zero, and resets the output length currently calculated by the calculation unit 131 to zero. Step S206: The updating unit 133 recalculates the fishing line winding length and updates the fishing line winding length information stored in the fishing line winding length information memory unit 141 based on the recalculated fishing line winding length. Step S208: The display control unit 134 displays information related to the fishing line reel length updated (recalculated) in step S206 on the display unit 102 for a predetermined time. The display performed in step S208 can be illustrated in FIG3 by using a pop-up screen PU. Step S210: If it is determined in step S202 that the zeroing setting operation is not performed in response to a high interruption, the tension correction unit 1322 in the reset unit 132 performs a tension correction zeroing setting process. The tension correction performed by the tension correction unit 1322 resets the number of drum rotations currently detected by the rotation sensor 106 to zero, and resets the output length currently calculated by the calculation unit 131 to zero. Furthermore, the tension correction unit 1322 corrects the length (unit yarn length) of the fishing line output from or wound onto the drum 4 by performing a predetermined calculation using a predetermined number of drum rotations used by the calculation unit 131 to calculate the output length. The unit yarn length can be corrected using known calculations. <Second Embodiment> Next, the second embodiment will be described. The electric fishing reel 1 in this embodiment is equipped with a communication unit 107. The communication unit 107 communicates with the user terminal 200 via short-range wireless communication such as Bluetooth (a Japanese registered trademark) or the Internet. User terminal 200 is a terminal owned by a user who uses the electric fishing reel 1 to fish. User terminal 200 can be a portable terminal such as a smartphone. Fishing support applications, such as those supporting the user's fishing, can be installed on user terminal 200. The display control unit 134 of the electric fishing reel 1 in this embodiment can display the updated fishing line reel length information on the display unit 102 in step S208 of FIG. 6, and send a message regarding the updated fishing line reel length information to the fishing support application of the user terminal 200 via the communication unit 107. The user terminal 200 can display the received fishing line reel length information through the fishing support application. In this way, the display control unit 134 of this embodiment can perform control to display the updated fishing line reel length information on the display unit of the user terminal 200. The user terminal 200, similar to that shown in Figure 3, can display the updated fishing line reel length for a specified time via a pop-up screen, for example. Furthermore, in addition to storing information about the received fishing line reel length, the user terminal 200 can also display the stored information about the fishing line reel length in response to the user's operation of the fishing support application. Also, the display control unit 134 can choose not to display the updated fishing line reel length information on the display unit 102 if the user terminal 200 is already displaying it. <Third Embodiment> Next, the third embodiment will be described. The electric fishing reel 1 of this embodiment can display information about the usage of the fishing line currently wound onto the reel 4 on the display unit 102. This information about the usage of the fishing line can be, for example, the date and time when the fishing line was initially wound onto the reel 4 (winding date and time). The winding date and time can be the date and time when the electric fishing reel 1 initially wound the fishing line onto the reel 4 (initial fishing line winding length), which is the information of the fishing line winding length information stored in the fishing line winding length information memory unit 141. Furthermore, the winding date and time can, for example, only display the date and not the time. By displaying the reeling date and time, the user can keep track of how long the fishing line wound on the reel 4 has been in use. The electric fishing reel 1 of this embodiment includes a reeling date and time memory unit 142 (Fig. 1) in the memory unit 104. The reeling date and time memory unit 142 stores the reeling date and time. The display of the reeling date and time can be performed by a pre-defined operation, such as using buttons provided with the electric fishing reel 1. For example, if the user instructs the display of the reeling date and time, the display control unit 134 displays the reeling date and time stored in the reeling date and time memory unit 142 on the display unit 102. Furthermore, the information displayed on the display unit 102 regarding the usage history of the fishing line can include not only the winding date and time, but also the period from when it was first wound onto the reel 4 until now (usage period). The usage period can be, for example, the number of days. Also, it can be combined with the second embodiment to cause the display control unit 134 to execute control and send a message to the user terminal 200 regarding the usage history of the fishing line, so that this information can be displayed on the user terminal 200. <Fourth Embodiment> Next, the third embodiment will be described. In this embodiment, the display control unit 134 of the fishing reel 1 displays, for example, a predetermined pattern of indicators or icons at a predetermined position on the display unit 102 after the display of information regarding the updated fishing line winding length on the pop-up screen PU has ended, indicating that the fishing line winding length update caused by the break has occurred. By displaying this information, the user, for example, during actual fishing, can remember that the fishing line winding length has shortened due to the break, and, for example, operate the fishing reel 1 as needed to display the current fishing line winding length and confirm it. Furthermore, the aforementioned indicators and icons can also display the number of breakages by using a predetermined pattern. For example, if the indicators and icons include a marker indicating the number of breakages, the number of breakages can be displayed by the quantity indicated by the indicators and icons. The number of high breakages displayed can be the total number of high breakages of the fishing line currently wound onto reel 4, or it can simply be the number of high breakages during this actual fishing session. Furthermore, the display of information regarding the length of the fishing line wound and the display of information regarding the usage of the fishing line in this embodiment can also be applied to fishing reels that are manually wound without being electrically driven by the spool 4. Furthermore, the program that enables the functions of the aforementioned electric fishing reel 1 can be recorded on a computer-readable recording medium. The electric fishing reel 1 can then be processed by loading the program onto the computer system and executing it. Here, "loading the program onto the recording medium and executing it on the computer system" includes installing the program into the computer system. The "computer system" here includes hardware such as an operating system (OS) and peripherals. Furthermore, the "computer system" can include multiple computer devices connected via a network of communication lines such as the Internet, WAN (Wide Area Network), LAN (Local Area Network), and dedicated lines. Moreover, "computer-readable recording medium" refers to portable media such as floppy disks (FD), optical disks (MO), ROMs, and CD-ROMs, or memory devices such as hard disks (HD) embedded in the computer system. Thus, the recording medium storing the program can be a non-temporary recording medium such as a CD-ROM. Furthermore, the format of the recording medium also includes formats where the program can be downloaded from a recording medium located inside or outside the transmission server. The code stored on the recording medium on the transmission server may differ from the code executable on the terminal device. That is, its form is not limited as long as it can be downloaded from the transmission server and installed and executed on the terminal device. Furthermore, the format may include a program divided into multiple parts, downloaded at different times and then combined by the terminal device, or a program whose respective transmission servers are different. Further, "computer-readable recording medium" also includes formats where the program is stored in the volatile memory (RAM) within the computer systems of servers and client machines that transmit programs via the network for a certain period of time. Moreover, the aforementioned program may only implement a portion of the functions described above. Furthermore, the aforementioned functions may also be implemented as a differential file (differential program) combined with a program already recorded in the computer system. 1: Electric fishing reel 2: Reel body 3: Operating lever 4: Drum 4a: Reel body 5: Clutch operating lever 6: Clutch mechanism 7: Motor housing 8: Motor 9: Motor bracket 10: Body frame 11: First side wall 12: Second side wall 13: Connecting component 14: Mounting foot 20: Side cover 21: First side cover 22: Second side cover 23: Connector part 24: Protective cap 30: Front cover 40: Meter counter housing 41: Display control panel 50: Handle shaft 51: Operating lever arm 52: Operating lever knob 53: Towing component 55 : Uniform line winding 101: Operation unit 102: Display unit 103: Control unit 104: Memory unit 105: Motor drive circuit 106: Rotation sensor 107: Communication unit 131: Calculation unit 132: Reset unit 133: Update unit 134: Display control unit 141: Line winding length information memory unit 142: Winding date and time memory unit 200: User terminal 1321: High-speed correction unit 1322: Tension correction unit L1: Left-right direction L2: Front-back direction O1: Handle axis O2: Drum axis PU: Pop-up screen [Figure 1] A diagram showing an example of the appearance of the electric fishing reel of this embodiment.
