Japanese Patent Application Laid-Open No. 2020-146025

Sometimes users want to accurately understand, in numerical form, the distance (reel length) of fishing line reeled in by performing a certain series of operations on the spool.

The present invention was developed in light of these circumstances, and aims to make it possible to accurately grasp, in numerical form, the distance that fishing line is reeled in as a result of a series of operations on the spool.

One aspect of the present invention for solving the above-mentioned problems is a display control device for a fishing reel, which includes a calculation unit that calculates a winding distance of fishing line by the spool performing a predetermined series of operations based on the rotational state of the spool from the start to the end of the series of operations applied to the spool in a rotational direction corresponding to the winding of the fishing line, and a display control unit that causes a display based on the winding distance calculated by the calculation unit to be displayed on a display unit.
According to the above configuration, the user can accurately grasp the difference in the water depth of the rig as a numerical value, which changes as the fishing line is reeled in, for example, by causing the spool to perform a predetermined series of operations in response to a jerk, etc.

Another aspect of the present invention is the above-mentioned display control device, wherein the display control unit may cause the display unit to display the difference in water depth at the rig position corresponding to when the series of operations begins and when the series of operations ends, based on the winding distance calculated by the calculation unit corresponding to when the series of operations ends.
With this configuration, when the spool completes a predetermined series of movements, the difference in the water depth of the tackle before and after the series of movements can be displayed. In other words, the difference in the water depth of the tackle can be presented to the user at a timing that is appropriate for the user.

Another aspect of the present invention is the above-mentioned display control device, wherein the display control unit may cause the display unit to display a display based on the winding distance calculated by the calculation unit while the series of operations is being performed.
According to the above configuration, when the spool is rotating in accordance with a series of operations, the difference in water depth can be displayed while changing as the fishing line is reeled in.

Another aspect of the present invention is the above-mentioned display control device, wherein the calculation unit may calculate the winding distance based on the line winding diameter of the spool corresponding to the rotational position of the spool from the start to the end of a series of operations.
According to the above configuration, the winding distance is calculated so as to reflect the change in the spool's line diameter due to the spool's rotational position, thereby making it possible to improve the accuracy of the water depth difference value displayed based on the winding distance.

Furthermore, one aspect of the present invention is the above-mentioned display control device, which includes a time measurement unit that measures the time from the start to the end of the series of operations, and the display control unit may control the display unit to display a display based on the time measured by the time measurement unit along with a display based on the winding distance.
According to the above configuration, the time required for a series of spool operations to be performed can be displayed together with the difference in water depth.

Another aspect of the present invention is a fishing reel equipped with the above-mentioned display control device.

Another aspect of the present invention is a display control method for a fishing reel, which includes a calculation step of calculating the reeling distance of fishing line by the spool performing a predetermined series of operations based on the rotational state of the spool from the start to the end of the series of operations performed in a rotational direction corresponding to the reeling of fishing line, and a display control step of causing a display based on the reeling distance calculated in the calculation step to be displayed on a display unit.

Another aspect of the present invention is a display control program that causes a computer acting as a display control device for a fishing reel to function as a calculation unit that calculates the reeling distance of fishing line by the spool performing a predetermined series of operations based on the rotational state of the spool from the start to the end of the series of operations that are applied to the spool in the rotation direction corresponding to the reeling of fishing line, and a display control unit that causes a display based on the reeling distance calculated by the calculation unit to be displayed on the display unit.

As explained above, the present invention has the effect of enabling the fishing line reel distance resulting from a series of operations on the spool of a fishing reel to be accurately determined in numerical form.

<Embodiment>
Hereinafter, an electric fishing reel 1 as a parameter setting device of this embodiment will be described with reference to the drawings.
In this embodiment, driving the spool means rotating the spool with power obtained by driving a motor or the like.
In this embodiment, the term "spool drive control" refers to control related to the drive of the spool, and includes control to rotate the spool, control to stop the rotation of the spool, control to change the rotation speed of the spool, etc.
In the following description, the "drive" of the spool may be referred to as "rotation drive" in order to clarify that it provides a rotational motion.
In the following description, a dual-bearing electric fishing reel 1 will be used as an example. In Figures 1 and 2, the scale of each component may be changed as needed to make the component large enough to be visible.

[Example of electric fishing reel structure]
1 and 2 show an example of the appearance of an electric fishing reel 1 according to this embodiment. The electric fishing reel 1 according to this embodiment mainly comprises a reel body 2 that can be attached to a fishing rod (not shown), a handle 3 that is attached to the reel body 2 so as to be rotatable about a handle axis O1, a spool 4 that is rotatable about a spool axis O2 that is parallel to the handle axis O1 with respect to the reel body 2 and onto which fishing line (not shown) is wound, and a clutch mechanism 6 that has a clutch operating lever 5.

The electric fishing reel 1 of this embodiment also includes a motor (not shown) that is disposed in a motor housing cylinder 7 provided in the reel body 2 and that drives the spool 4 to rotate.
The electric fishing reel 1 also includes a motor holder 9 that is combined with the reel body 2 so as to close the motor housing cylinder 7 and fixes the motor to the reel body 2.

In this embodiment, the handle axis O1 and the spool axis O2 are arranged parallel to each other, and the direction along these axes is defined as the left-right direction L1. Furthermore, the direction perpendicular to the left-right direction L1 and along the direction in which the fishing line wound on the spool 4 is released is defined as the front-rear direction L2.
Furthermore, the direction in which the fishing line is released from the spool 4 in the front-to-rear direction L2 is defined as the front, and the opposite direction is defined as the rear, and left and right are defined from the perspective of the electric fishing reel 1 as seen from the rear side (the angler's side). Therefore, Figure 1 is a perspective view of the electric fishing reel 1 as seen diagonally from above and from the rear left.

The reel body 2 comprises a main body frame 10, side covers 20 that cover both the left and right sides of the main body frame 10, and a front cover 30 that covers the front side of the main body frame 10.

The main body frame 10 is a molded part made of, for example, synthetic resin or metal (e.g., aluminum die-cast). The main body frame 10 includes a first side wall 11 and a second side wall 12 that are arranged facing each other in the left-right direction L1 with the spool 4 in between, 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 a left side wall located on the left side (LH) of the spool 4. In contrast, the second side wall 12 is a right side wall located on the right side (RH) of the spool 4. The handle 3 is located further to the right (RH) of the second side wall 12 and is attached to the main body frame 10 using the second side wall 12.
Therefore, the electric fishing reel 1 of this embodiment is a right-hand handle type reel. The second side wall 12 is formed to protrude downward more than the first side wall 11 because the connector portion 23 and the like are attached to the second side wall 12.

The connecting member 13 is formed in a plate shape that connects the first side wall 11 and the second side wall 12 to each other in the left-right direction L1, and is disposed near the lower part of the first side wall 11. As a result, the first side wall 11 and the second side wall 12 are firmly connected via the connecting member 13.
At the center of the connecting member 13 in the left-right direction L1, an attachment leg piece 14 for attaching the electric fishing reel 1 to a fishing rod is formed so as to extend in the front-rear direction L2.

In the main body frame 10 configured as described above, at least the motor housing cylinder 7, which houses the motor inside, the spool 4, and the clutch operating lever 5 are arranged between the first side wall 11 and the second side wall 12.

The spool 4 is disposed between the first side wall 11 and the second side wall 12 so as to be located rearward of the handle axis O1. The motor housing cylinder 7 is disposed between the first side wall 11 and the second side wall 12 so as to be located forward of the handle axis O1. Therefore, the electric fishing reel 1 of this embodiment is a so-called spool-out motor type, in which the motor is disposed forward of the spool 4.

The side cover 20 comprises a first side cover 21 that is combined with the main frame 10 to cover the first side wall 11, in which the opening for the motor housing cylinder 7 is formed, from the left side (LH), and a second side cover 22 that is combined with the main frame 10 to cover the second side wall 12 from the right side (RH).

The first side cover 21 is formed so as to bulge out toward the left side (LH) and is fixed to the first side wall 11 with, for example, screws.
The second side cover 22 is formed so as to bulge out toward the right side (RH) and is fixed to the second side wall 12 with, for example, screws.
A connector 23 for connecting a power reel cord for supplying power from an external power source or a portable battery (not shown) is attached to the lower front portion of the second side cover 22 with its connecting end facing downward. In each drawing, the connecting end is shown protected by a protective cap 24.

The front cover 30 is attached to the main frame 10 so as to cover the front portion of the main frame 10 from the front. Specifically, the front cover 30 is attached to the front portions of the first side wall 11 and the second side wall 12 so as to cover the motor housing cylinder 7 from the front, and is secured to the first side wall 11 and the second side wall 12, for example, with screws. The front cover 30 is attached so as not to block the movement area of the level wind 55, which will be described later.

A counter case 40 is provided on the top of the main body frame 10 configured as described above. The counter case 40 is positioned between the first side wall 11 and the second side wall 12 and is fixed to the top of the first side wall 11 and the top of the second side wall 12, for example, by screws.

The top surface of the counter case 40 body is configured as a display and operation panel 41. The display and operation panel 41 is a part that displays information to the user of the electric fishing reel 1 and allows the user to operate buttons, switches, and other controls.

Figure 3 shows the display and operation panel 41 of the electric fishing reel 1. As shown in the figure, the display and operation panel 41 includes an operation unit 101 and a display unit 102.

The operation unit 101 is a component where buttons are operated by the user. In the example shown in the figure, three buttons are arranged on the operation unit 101 as buttons to be operated: a first button 111-1, a second button 111-2, and a third button 111-3. In the following explanation, when there is no need to distinguish between the first button 111-1, the second button 111-2, and the third button 111-3, they will be referred to as buttons 111.

In the figure, the buttons 111 are arranged in a vertical direction with the second button 111-2 on top and the third button 111-3 on the bottom. The first button 111-1 is located to the left of the positions where the second button 111-2 and the third button 111-3 are arranged, and is located midway between the second button 111-2 and the third button 111-3 in the vertical direction.
In such an arrangement of the buttons 111, the second button 111-2 and the third button 111-3 can function as an up button and a down button, respectively, for changing parameter values, selecting items, etc., and the user will find these buttons easy to use.

The operating unit 101 is also provided with a winding switch 112. The winding switch 112 is an operator that is operated to rotate the spool 4 and wind up the fishing line.
The winding switch 112 is a switch that is operated to automatically wind up the fishing line. The winding switch 112 is a seesaw-type pressure-sensitive switch that can be operated by pressing down the upper switch portion 112a or the lower switch portion 112b.

The display unit 102 is a component that displays predetermined content in response to the operation of the electric fishing reel 1. There are no particular limitations on the display device that can be provided as the display unit 102, but examples include a liquid crystal display device and an organic EL display device.

1 and 2, the explanation will be returned to Figs. 1 and 2. The handle 3 is used for manually reeling in the fishing line. The handle 3 is located to the right (RH) of the main body frame 10 and the first side cover 21. The handle 3 includes a handle shaft 50 rotatable about a handle axis O1, a handle arm 51 non-rotatably attached to the handle shaft 50, and a handle knob 52 rotatably attached to the end of the handle arm 51 about an axis parallel to the handle axis O1.
A drag 53 (star drag) is disposed coaxially with the handle axis O1 between the handle arm 51 and the first side cover 21. This drag 53 applies a desired drag force to the spool 4 when winding the fishing line, thereby braking the rotation of the spool 4 and helping to prevent the fishing line from breaking.

The rotational torque from the handle 3 configured in this manner is transmitted directly to the spool 4 via a rotation transmission mechanism (not shown) when the clutch mechanism 6 is in the clutch-on state.
In this embodiment, the electric fishing reel 1 is described as a so-called single handle type in which the handle knob 52 is attached to one end of the handle arm 51, but is not limited to this. For example, the electric fishing reel 1 may be a so-called double handle type in which the handle knobs 52 are attached to both ends of the handle arm 51 and the center of the handle arm 51 is non-rotatably attached to the handle shaft 50.

The spool 4 is arranged between the first side wall 11 and the second side wall 12 of the frame body, and is supported rotatably around the spool axis O2 on each of the first side wall 11 and the second side wall 12 via bearings not shown.
The spool 4 comprises a spool rotating shaft portion (not shown) that rotates around the spool axis O2, and a bobbin trunk portion 4a that is arranged coaxially with the spool rotating shaft portion and rotates in conjunction with the spool rotating shaft portion.

The clutch mechanism 6 can be switched between a clutch-on state in which rotational torque from the handle 3 can be transmitted to the spool 4 via a rotation transmission mechanism (not shown) and a clutch-off state in which rotational torque cannot be transmitted, by operating the clutch operating lever 5. Therefore, in the clutch-on state, by rotating the handle 3, the rotational torque associated with the rotation of the handle 3 can be transmitted to the spool 4, making it possible to rotate the spool 4 about the spool axis O2. This allows for manual winding.
When the clutch mechanism 6 is in the clutch-off state, the rotational torque caused by the rotation of the handle 3 is not transmitted to the spool 4, and the spool 4 is in a freely rotatable state (spool-free state).

The clutch operating lever 5 is a switching lever for switching the clutch mechanism 6 between a clutch-on state and a clutch-off state. The clutch operating lever 5 is located between the first side wall 11 and the second side wall 12, rearward of the spool 4, and is movable up and down so as to swing around the spool axis O2.

The rotation transmission mechanism is configured to transmit rotational torque to the spool 4 while accelerating the rotation of the handle 3. Furthermore, when the clutch mechanism 6 is in the clutch-on state, the rotation transmission mechanism is configured to transmit the rotational torque associated with the rotation of the handle 3 not only to the spool 4, but also to the level wind mechanism (not shown). The level wind mechanism is a mechanism that ensures that the fishing line is wound evenly and uniformly onto the spool 4.

Furthermore, when the clutch mechanism 6 is in the clutch-on state and the motor is driven, the rotational torque generated by the motor's drive can be transmitted to the spool 4. This enables automatic winding. The rotational transmission mechanism transmits the rotational torque to the spool 4 while decelerating the motor's rotation.

[About the electric jigging mode]
When the electric fishing reel 1 of this embodiment is in the electric jigging mode, it can perform a fishing line winding operation in response to the user's operation of the winding switch 112 as follows.

In the electric jigging mode, the upper switch portion 112a of the winding switch 112 is assigned to the operation of turning on and off the rotational drive of the spool 4 for winding up the fishing line.
In other words, when the user starts pressing the upper switch portion 112a, the rotation of the spool 4 begins, and the fishing line also begins to be reeled in. As long as the user continues to press the upper switch portion 112a, the rotation of the spool 4 continues, and the fishing line also continues to be reeled in. When the user releases the pressure on the upper switch portion 112a, the rotation of the spool 4 stops, and the reeling in of the fishing line also stops.
In the electric jigging mode, when the upper switch portion 112a is first pressed, the fishing line is reeled in at a spool rotation speed (intermediate reeling speed) that is less than the preset maximum speed for electric manual jigging. If the upper switch portion 112a is subsequently pressed further while continuing to be pressed, the fishing line is reeled in at the maximum reeling speed.

In addition, in the electric jigging mode, the lower switch portion 112b of the winding switch 112 is assigned an operation for executing an automatic jigging operation (automatic jerk).
In other words, when the user presses the lower switch portion 112b once (one click operation), the spool 4 is rotated for a certain period of time in accordance with the preset drive control information, and the fishing line is reeled in.

The drive control parameters constituting the drive control information corresponding to the automatic jig operation of this embodiment are the drive time [TIME], speed [SPEED], and acceleration [ACCEL].
The drive time [TIME] is the time for which the spool 4 is driven to rotate in one automatic jigging operation.
The speed [SPEED] is the rotational speed of the spool 4 when winding up the fishing line during automatic jigging operation.
The acceleration [ACCEL] is the acceleration (angular acceleration) when the spool 4 reaches the speed [SPEED] after starting to rotate during the automatic jig operation.

The parameter value for drive time [TIME] (drive time parameter value VT), speed [SPEED] (speed parameter value VS), and acceleration [ACCEL] (acceleration parameter value VA) can each be changed by the user through operations as described below.

The drive time parameter value VT may be a value expressed in seconds with a predetermined number of decimal places, for example.
The speed parameter value VS may be set to a value corresponding to each of a predetermined number of speed stages (for example, about 30 stages) each corresponding to a predetermined speed.

The acceleration parameter value VA may be a value corresponding to a number of stages, each corresponding to a predetermined acceleration. Specifically, in this embodiment, the acceleration parameter value VA has three stages: VA_H, which corresponds to a predetermined acceleration as a high acceleration; VA_M, which corresponds to a predetermined acceleration as a medium acceleration; and VA_L, which corresponds to a predetermined acceleration corresponding to a decreasing speed.

For example, the acceleration parameter value VA may be set in detail by specifying the acceleration value. However, in this case, it may be more difficult for the user to determine which value is appropriate. Therefore, in this embodiment, the acceleration parameter value VA is changed using a relatively small number of stages, such as three, so that the user can clearly understand the difference in spool rotation behavior at each stage. Note that there is no particular limit to the number of stages for the acceleration parameter value VA.

4A shows an example of the behavior of the spool 4 corresponding to one automatic jig operation based on the drive control parameters set for the drive time [TIME], speed [SPEED], and acceleration [ACCEL]. In the figure, the horizontal axis represents time and the vertical axis represents rotation speed.
The figure shows the spool behavior GH when the acceleration parameter value VA_H is set, the spool behavior GM when the acceleration parameter value VA_M is set, and the spool behavior GL when the acceleration parameter value VA_L is set.

When the acceleration parameter value VA_H is set, the spool behavior GH is as follows.
At time t0, in response to a user pressing the lower switch portion 112b of the winding switch 112 once, the electric fishing reel 1 starts rotating the spool 4. That is, the electric fishing reel 1 starts applying a voltage (motor drive signal) to drive the motor from time t0. However, even if the rotation of the spool starts at time t0, there is a certain time lag (delay) before the rotation is transmitted to the spool 4. Therefore, the spool 4 starts rotating at time t1, a certain time after time t0.

The spool 4 begins to rotate at time t1, and its rotation speed increases at an acceleration rate determined by the set acceleration parameter value VA_H. At time t2(1), the rotation speed of the spool 4 reaches the rotation speed (target rotation speed vtg) corresponding to the set speed parameter value VS. From time t2(1) onwards, the spool 4 is controlled to rotate at a constant rotation speed corresponding to the speed parameter value VS.

The electric fishing reel 1 begins measuring (timing) the drive duration T at time t0, when the rotation of the spool 4 begins. When the measured value of the drive duration T reaches the drive duration parameter value VT at time t3, the supply of current to the motor is stopped to stop the rotation of the spool 4.

When the supply of current to a motor is stopped, inertia prevents the motor from immediately stopping, but rather rotates a certain distance before stopping, a phenomenon known as overrun. In the example shown in the figure, the rotational speed of spool 4 is decelerated during the period of overrun from time t3 onwards, and spool 4 stops rotating at time t4.

Furthermore, when the acceleration parameter value VA_M is set, the spool behavior GM is as follows.
In this case as well, at time t0, in response to the user pressing the lower switch portion 112b of the winding switch 112 once, the electric fishing reel 1 applies a motor drive signal to start driving the spool to rotate and starts measuring the drive duration T. Then, at time t1, a certain period of time after time t0, the spool 4 starts to rotate.

The spool 4 begins rotating at time t1, and its rotation speed increases at an acceleration rate determined by the set acceleration parameter value VA_M. In this case, the rotation speed of the spool 4 reaches the target rotation speed vtg at time t2(2), which is later than time t(1). From time t2(2) onwards, the spool 4 is controlled to rotate at a constant rotation speed corresponding to the speed parameter value VS.

Then, at time t3, when the measured drive duration T reaches the drive time parameter value VT, the supply of current to the motor is stopped, and at time t4, after an overrun period, the rotation of the spool 4 is stopped.

Furthermore, when the acceleration parameter value VA_L is set, the spool behavior GL is as follows.
In this case as well, at time t0, in response to the user pressing the lower switch portion 112b of the winding switch 112 once, the electric fishing reel 1 applies a motor drive signal to start driving the spool to rotate, and starts measuring the drive duration T. The spool 4 starts rotating at time t1, which is a certain time lag (delay) after time t0 when the application of the motor drive signal started.

The spool 4 begins to rotate at time t1, and its rotation speed increases at an acceleration rate determined by the set acceleration parameter value VA_L. In this case, the rotation speed of the spool 4 reaches the target rotation speed vtg at time t2(3), which is later than time t2(2). From time t2(3) onwards, the spool 4 is controlled to rotate at a constant rotation speed corresponding to the speed parameter value VS.

Then, at time t3, when the measured drive duration T reaches the drive time parameter value VT, the supply of current to the motor is stopped, and at time t4, after an overrun period, the rotation of the spool 4 is stopped.

Note that the time t1 at which the spool 4 begins to rotate may vary depending on the acceleration parameter value VA. However, for ease of understanding, the figure shows an example in which the time t1 for the spool behaviors GH, GM, and GL is the same regardless of the acceleration parameter value VA.

The electric fishing reel 1 of this embodiment drives the motor using PWM (Pulse Width Modulation) control to rotate the spool 4. Therefore, when driving the motor, the electric fishing reel 1 sets the pulse width duty ratio for each period of the voltage applied to the motor (motor drive signal).

Figure 4(B) shows an example of the duty ratio transitions DH, DM, and DL of the motor drive signal corresponding to the spool behaviors GH, GM, and GL shown in Figure 4(A). In this figure, the horizontal axis represents time and the vertical axis represents the duty ratio.

As the duty ratio transition DH corresponding to the spool behavior GH, first, during the period from time t0 until the spool rotation speed reaches the target rotation speed vtg (an example of an initial period), application of a motor drive signal with an initial duty ratio dh corresponding to the acceleration parameter value VA_H begins. As a result, the spool 4 begins to rotate at time t1 after a time lag has elapsed, and the rotation speed increases due to acceleration corresponding to the motor drive signal with the initial duty ratio dh. Then, at time t2(1), when the rotation speed of the spool 4 reaches the target rotation speed vtg, the duty ratio changes to a constant-speed-corresponding duty ratio ds for driving the spool 4 to rotate at a constant target rotation speed vtg.
From time t2(1) onward, the rotational speed of the spool 4 is detected, and feedback control is performed to change the constant-speed duty ratio ds so that the detected rotational speed becomes the target rotational speed vtg. For the sake of clarity, the figure shows the constant-speed duty ratio ds as being constant and not changing with the progress of events, but the constant-speed duty ratio ds actually fluctuates due to feedback control. For example, the constant-speed duty ratio ds required to maintain the target rotational speed vtg fluctuates depending on the condition of the tackle in the water, the length of line wound per rotation of the spool 4 corresponding to the line diameter, and other factors.

However, the range of the constant-speed duty ratio ds that can be controlled for each stage of the speed parameter value VS is predetermined. By defining the range of the constant-speed duty ratio ds for each speed parameter value VS in this way, the constant-speed duty ratio ds can be limited so that it does not reach 100%, even when a high load is applied to the motor at a low speed setting. This prevents a situation where the actual winding speed does not change even when the speed parameter value VS is changed.

For example, in constant tension mode, in which the fishing line is reeled in at a constant tension, the duty ratio is controlled to be constant at a predetermined value. However, even in constant tension mode, the tension changes depending on the line diameter wound on the spool 4, so the duty ratio is controlled to change in response to these tension changes.

Then, at time t3, when the measured drive duration T reaches the drive time parameter value VT, the application of the motor drive signal is stopped.

Furthermore, as for the duty ratio transition DM corresponding to the spool behavior GM, first, from time t0, application of a motor drive signal with an initial duty ratio dm corresponding to the acceleration parameter value VA_M begins. Because the initial duty ratio dm corresponds to medium acceleration, it is smaller than the initial duty ratio dh corresponding to the acceleration parameter value VA_H corresponding to high acceleration. In this case, the acceleration of the rotation of the spool 4 from time t1 onwards is lower than in the case of the initial duty ratio dh corresponding to high acceleration. Then, from time t(2) when the target rotation speed vtg is reached, the constant-speed corresponding duty ratio ds is maintained. Thereafter, at time t3 when the drive duration T reaches the drive time parameter value VT, application of the motor drive signal is stopped.

Furthermore, as for the duty ratio transition DL corresponding to the spool behavior GL, first, from time t0, application of a motor drive signal begins with an initial duty ratio dl corresponding to the acceleration parameter value VA_L. Because the initial duty ratio dl corresponds to low acceleration, it is smaller than the initial duty ratio dm corresponding to the acceleration parameter value VA_M corresponding to medium acceleration. In this case, the acceleration of the rotation of the spool 4 from time t1 onwards is lower than in the case of the initial duty ratio dm corresponding to medium acceleration. Then, from time t(3) onwards when the target rotation speed vtg is reached, the constant speed-corresponding duty ratio ds is maintained. Thereafter, when the drive duration T reaches time t3, the drive time parameter value VT, application of the motor drive signal is stopped.

As can be seen from the diagram, the electric fishing reel 1 changes the duty ratio of the motor drive signal over time in accordance with the parameter values of the drive control parameters (drive time parameter value VT, speed parameter value VS, acceleration parameter value VA), thereby driving the rotation of the spool 4 in response to automatic jigging operations.

As a drive control parameter, the acceleration [ACCEL] may not be set, and the rotation of the spool 4 may be started from the beginning with an acceleration corresponding to a fixed duty ratio, or with a duty ratio corresponding to the speed parameter value VS.
However, for example, when a user actually moves a fishing rod while jigging, changing the sharpness of the initial jerk of the jig depending on the situation can lead to a catch. Therefore, by providing a drive control parameter for acceleration [ACCEL] as in this embodiment, the sharpness of the initial jerk of the jig can be changed according to the user's intention during automatic jigging operations.

When the lower switch portion 112b of the winding switch 112 is operated once, the electric fishing reel 1 changes the duty ratio of the motor drive signal according to the parameter values of the drive control parameters, as shown in Figure 4(B). This changes the rotational speed of the spool 4 as shown in Figure 4(A), and one automatic jigging operation is performed. By winding up the fishing line at a winding speed that changes depending on the rotational speed of the spool 4, automatic jigging movement is achieved.

[Setting drive control parameters for automatic jig operation]
Next, an example of the procedure for setting the parameter values (drive time parameter value VT, speed parameter value VS, acceleration parameter value VA) of the drive control parameters (drive time [TIME], speed [SPEED], and acceleration [ACCEL]) corresponding to the automatic jig operation will be described. In this embodiment, the drive control parameters corresponding to the automatic jig operation can be set while the electric jigging mode is on.
In this embodiment, setting of a drive control parameter includes selecting a drive control parameter whose value is to be changed, and changing the parameter value of the drive control parameter selected as the change target.

5 shows an example of the display on the display unit 102 when the electric jigging mode is on. The display unit 102 in the figure has a speed/depth difference area AR10, a depth area AR20, and a parameter display area AR30.
The speed/depth difference area AR10 is an area in which the currently set rotation speed of the spool 4 is displayed in stages. The speed/depth difference area AR10 can also display the depth difference of the tackle (difference in water depth) caused by reeling in the fishing line in the electric jigging mode.
Specifically, when electric manual jigging is performed, the speed/depth difference area AR10 displays the depth difference, which is the difference between the water depth of the rig when the upper switch section 112a is pressed and the spool 4 starts to rotate, and the water depth of the rig when the upper switch section 112a is then released and the rotation of the spool 4 stops.
In addition, when one click of the lower switch section 112b is performed for automatic bait operation, the speed/depth difference area AR10 displays the depth difference, which is the difference between the water depth of the rig when rotation of the spool 4 begins according to the drive control information and the water depth of the rig when rotation of the spool 4 subsequently stops.

FIG. 6 shows an example in which the depth difference is displayed in the speed/depth difference area AR10 instead of the rotation speed of the spool 4 in response to the above-mentioned electric manual jigging or automatic jigging operation being performed while the electric jigging mode is on.
The display mode of the water depth difference in the figure is an example, and the water depth difference may be displayed in another area of the display unit 102.

Referring back to Figure 5 for the explanation, the water depth area AR20 is an area that displays the water depth at which the tackle is currently located.

The parameter display area AR30 is an area where the currently set parameter values for each drive control parameter are displayed. The parameter display area AR30 includes a drive time display area AR31-1, a speed display area AR31-2, and an acceleration display area AR31-3. When no particular distinction is needed, the drive time display area AR31-1, the speed display area AR31-2, and the acceleration display area AR31-3 will be referred to as the individual parameter display area AR31.
The drive time display area AR31-1 is an area in which the currently set drive time parameter value VT is displayed.
The speed display area AR31-2 is an area where the currently set speed parameter value VS is displayed.
The acceleration display area AR31-3 is an area in which the currently set acceleration parameter value VA is displayed.

10 shows an example in which the drive time display area AR31-1 is highlighted in the parameter display area AR30. The state in which the drive time display area AR31-1 is highlighted in this manner indicates that, of the drive control parameters (drive time [TIME], speed [SPEED], and acceleration [ACCEL]), the drive time [TIME] has been selected as the parameter value to be changed.
The parameter display area AR30 is in a state where one of the drive time display area AR31-1, speed display area AR31-2, and acceleration display area AR31-3 is highlighted depending on which of the drive control parameters (drive time [TIME], speed [SPEED], and acceleration [ACCEL]) is selected to be changed.

In the figure, the highlighting mode is such that the individual parameter display area AR31 of the selected object is displayed in inverted light and dark compared to the other individual parameter display areas AR31. The highlighting mode is not particularly limited, and for example, the frame or text of the individual parameter display area AR31 of the selected object may be made bold, or in the case of a color display, the background color or text color may be changed.

In addition, when the parameter display area AR30 is initially displayed in response to the electric jigging mode being turned on, the individual parameter display area AR31 may be highlighted, for example, in the state it was in when the electric jigging mode was last turned off. Alternatively, the individual parameter display area AR31 corresponding to a specific predetermined drive control parameter may be highlighted.

When the parameter display area AR30 shown in Figure 5 is displayed in the electric jigging mode, the user can change the parameter value (drive time parameter value VT) of the drive time [TIME] selected as the target for change by performing the operations described below.
In this case, the user continues to press the first button 111-1 on the operation unit 101. In other words, the user sets the first button 111-1 to a continuous operation state in which the pressing operation is continued. This enables the electric fishing reel 1 to accept an operation on the second button 111-2 or the third button 111-3 as an operation to change a parameter value.

To increase the drive time parameter value VT, the user operates the second button 111-2 while continuing to press the first button 111-1. Each time the second button 111-2 is pressed, the drive time parameter value VT is incremented.
Furthermore, when the user wants to decrease the drive time parameter value VT, he or she operates the third button 111-3 while continuing to press the first button 111-1. Each time the third button 111-3 is pressed, the drive time parameter value VT is decremented.

In response to the user pressing and holding the second button 111-2, the drive time parameter value VT may be continuously incremented until the second button 111-2 is released. In response to the user pressing and holding the third button 111-3, the drive time parameter value VT may be continuously decremented until the third button 111-3 is released.

The drive time display area AR31-1 displays the drive time parameter value VT changed by the above operation. This allows the user to confirm the drive time parameter value VT changed by their own operation.

When the user changes the drive time parameter value VT to the desired value as described above, they release the pressure on the first button 111-1 that they have been holding down. This causes the electric fishing reel 1 to no longer accept operations on the second button 111-2 and the third button 111-3, which change the drive time parameter value VT. The electric fishing reel 1 also confirms the drive time parameter value VT as the value displayed in the drive time display area AR31-1 when the pressure on the first button 111-1 was released, completing the setting of the drive control parameters.

When the first button 111-1 is pressed, the electric fishing reel 1 may disable operation of the winding switch 112. In other words, when the first button 111-1 is pressed, the spool 4 may not rotate even if the user operates the upper switch portion 112a, and the automatic baiting operation may not be performed even if the user operates the lower switch portion 112b.
This prevents the rotation of the spool 4 from becoming unstable due to the drive control parameters being changed while the spool 4 is rotating.

In addition, in the electric jigging mode, the user can select the drive control parameter whose parameter value is to be changed by the following operation.
In the electric jigging mode, the user does not press the first button 111-1, but operates the second button 111-2 or the third button 111-3.

Each time the user presses the second button 111-2, the individual parameter display area AR31 one row above the previously highlighted individual parameter display area AR31 in the parameter display area AR30 is highlighted. The drive control parameter corresponding to the newly highlighted individual parameter display area AR31 is selected as the parameter value to be changed.

Note that if the second button 111-2 is pressed once while the topmost individual parameter display area AR31 is highlighted, the operation may be invalidated, or the highlighting may cycle to the bottommost individual parameter display area AR31.

Furthermore, each time the user presses the third button 111-3, the individual parameter display area AR31 one row below the previously highlighted individual parameter display area AR31 in the parameter display area AR30 is highlighted. In this case, too, the drive control parameter corresponding to the newly highlighted individual parameter display area AR31 is selected as the parameter value to be changed.

Note that if the third button 111-3 is pressed once while the bottom-most individual parameter display area AR31 is highlighted, the operation may be invalidated, or the highlighting may cycle to the top-most individual parameter display area AR31.

In this way, the electric fishing reel 1 of this embodiment is capable of performing an operation (parameter change operation) to change the parameter values of the drive control parameters of the drive time [TIME], speed [SPEED], and acceleration [ACCEL].
Furthermore, the operation to change the parameter values of the drive control parameters is performed while the electric jigging mode is on. In other words, the user can change the parameter values of the drive control parameters in the electric jigging mode without changing from the electric jigging mode to a setting mode for changing the drive control parameters, for example. This allows the user to quickly change the drive control parameters for the automatic jigging operation even while fishing.

Furthermore, the operation to change a parameter value and the operation to select a drive control parameter whose parameter value is to be changed are both performed using the second button 111-2 and the third button 111-3. By using the same controls for both the operation to change a parameter value and the operation to select a drive control parameter in this way, the number of controls provided on the electric fishing reel 1 can be reduced.

[Example of functional configuration of an electric fishing reel]
An example of the functional configuration of the electric fishing reel 1 will be described with reference to Fig. 7. In this figure, the same parts as those in Figs. 1 and 2 are designated by the same reference numerals and the description thereof will be omitted where appropriate.
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 spool 4, and a rotation sensor 106.

The control unit 103 executes various controls in the electric fishing reel 1. The functions of the control unit 103 are realized by a CPU (Central Processing Unit) provided in the electric fishing reel 1 executing a program.
The control unit 103 includes a parameter setting unit 131 , a spool drive control unit 132 , a calculation unit 133 , a display control unit 134 , and a time measurement unit 135 .
The parameter setting unit 131 sets the parameter values of the drive control parameters in accordance with the operation performed on the operation unit 101 .
The spool drive control unit 132 executes drive control of the spool 4 based on the drive control information.
The calculation unit 133 calculates the winding distance of the fishing line by the spool 4 performing the above-mentioned series of operations based on the rotational state of the spool 4 from the start to the end of a predetermined series of operations applied to the spool 4 in the rotational direction corresponding to the winding of the fishing line.
Specifically, when electric manual jigging is performed in electric jigging mode, the calculation unit 133 calculates the winding distance that occurs when the spool 4 rotates in response to the start of pressing the upper switch unit 112a, and then the rotation of the spool 4 stops in response to the release of pressure on the upper switch unit 112a.
In addition, when a single click operation of the lower switch section 112b is performed for automatic jigging operation in the electric jigging mode, the calculation section 133 calculates the winding distance that occurs when the rotation of the spool 4 starts in accordance with the drive control information and then stops.
The display control unit 134 controls the display on the display unit 102. In the electric jigging mode, the display control unit 134 can display the water depth difference based on the reeling distance calculated by the calculation unit 133 in the speed/water depth difference area AR10.
The time measurement unit 135 measures the time from when the rotation of the spool 4 starts to when it stops in response to the automatic jigging operation in the electric jigging mode.

The memory unit 104 stores various information corresponding to the electric fishing reel 1. The memory unit 104 includes a drive control information memory unit 141, a duty ratio memory unit 142, an intermediate winding speed memory unit 143, and a line length/spool rotation position table memory unit 144.

The drive control information storage unit 141 stores drive control information. The drive control information is information used to control the drive of the spool 4 during automatic jigging operations. As described above, the drive control information includes the drive control parameters of drive time [TIME], speed [SPEED], and acceleration [ACCEL].

The duty ratio storage unit 142 stores the duty ratio of the motor drive signal corresponding to the acceleration parameter value VA. Specifically, the duty ratio storage unit 142 stores initial duty ratios dh, dm, and dl corresponding to the acceleration parameter values VA_H, VA_M, and VA_L.
If a constant speed corresponding duty ratio is determined for each speed parameter value VS, the duty ratio storage unit 142 may store the constant speed corresponding duty ratio in association with each speed parameter value VS.

The intermediate winding speed memory unit 143 stores the intermediate winding speed. The intermediate winding speed is a parameter for the rotation speed of the spool 4 that is specified when the spool 4 is rotated in response to pressing the upper switch unit 112a in electric jigging mode. The intermediate winding speed can be set arbitrarily by the user, for example, within a range lower than the maximum rotation speed of the spool 4.

The line length/spool rotational position table storage unit 144 stores a line length/spool rotational position table. The line length/spool rotational position table is a table that indicates the length of fishing line (line length) wound around the spool 4 for each rotational position of the spool 4 (spool rotation position). The spool rotational position corresponds to the total number of rotations of the spool 4 detected by the rotation sensor 106 from the start of winding the fishing line to the end of winding. The number of rotations here refers to the number of times the spool 4 has made one rotation.
The line length/spool rotation position table is used by the control unit 103 to calculate the water depth, and by the calculation unit 133 to calculate the winding distance, etc.

The line length per unit rotation of the spool 4 corresponding to each spool rotation position can be defined as approximating a linear line. Based on this, the control unit 103 calculates a linear line, for example, from the relationship between the line length when unwinding from the spool rotation position where winding is completed and the spool rotation number when winding fishing line onto the spool 4, and the total number of spool rotations during winding. The control unit 103 calculates the relationship between line length and spool rotation position by integrating the linear line. The relationship between line length and spool rotation position calculated in this way is stored as a line length/spool rotation position table. The water depth and fishing line winding distance calculated using the line length/spool rotation position table reflect changes in line diameter depending on the spool rotation position.

The motor drive circuit 105 drives the motor 8 under the control of the spool drive control unit 132. The spool drive control unit 132 changes the rotation speed of the motor 8 by changing the duty ratio of the pulse width of the motor drive signal through PWM control.
The rotation sensor 106 detects the spool rotation position, the number of spool rotations, the rotation speed of the spool 4 (spool rotation speed), and the like.

[Example of processing procedure]
An example of a processing procedure that the electric fishing reel 1 executes in response to an operation on the winding switch 112 when the electric jigging mode is turned on will be described with reference to the flowchart of FIG.
Step S101: In the electric fishing reel 1, the spool drive control unit 132 determines whether or not a pressing operation has been started on the upper switch portion 112a of the winding switch 112. In the electric jigging mode, as described above, while the upper switch portion 112a continues to be pressed, the spool 4 is driven to rotate and the fishing line is wound up.

Step S102: When it is determined that the pressing operation on the upper switch unit 112a has begun, the spool drive control unit 132 determines whether the first button 111-1 is in a pressed state in addition to the pressing operation on the upper switch unit 112a.
If it is determined that the first button 111-1 is pressed, the drive control parameters are changed (incremented), but in the figure, the procedure for changing the drive control parameters is omitted for convenience, and the process proceeds to step S112. In this case, step S104 is skipped, and the spool 4 is not driven to rotate, so no fishing line is reeled in. In other words, when the first button 111-1 is pressed, the spool drive control unit 132 does not accept the operation of pressing the upper switch unit 112a as an operation to rotate the spool 4.

Step S103: If it is determined that the first button 111-1 is not pressed, the calculation unit 133 acquires the spool rotation position (starting spool rotation position) detected by the rotation sensor 106 at the timing when pressing of the upper switch unit 112a begins in step S101.

Step S104: The spool drive control unit 132 starts drive control to rotate the spool 4 at the intermediate winding speed stored in the intermediate winding speed memory unit 143.

Step S105: After starting drive control to rotate the spool 4 at the intermediate winding speed in step S104, the spool drive control unit 132 determines whether the pressing force detected by the pressed upper switch unit 112a has increased.

Step S106: If it is determined that the pressing force has increased, the spool drive control unit 132 sets the rotation speed of the spool 4 to a predetermined value higher than the current value, and drives the spool 4 to rotate. Note that if the current rotation speed of the spool 4 is at its maximum, the processing of step S106 may be skipped.

Step S107: The spool drive control unit 132 determines whether the pressed state of the upper switch unit 112a that has continued up to this point has been released.
If it is determined that the pressed state of the upper switch portion 112a has not been released, the process returns to step S105.

Step S108: If it is determined in step S107 that the pressed state of the upper switch unit 112a has been released, the spool drive control unit 132 stops the rotational drive of the spool 4.

Step S109: The calculation unit 133 acquires the spool rotation position (stopped spool rotation position) detected by the rotation sensor 106 when the rotational drive of the spool 4 is stopped in step S108.

Step S110: The calculation unit 133 calculates the length of fishing line (winding distance) reeled in by the rotation of the spool 4 in response to the current pressing of the upper switch unit 112a. To do this, the calculation unit 133 obtains the line length for each spool rotation position from the line length/spool rotation position table, corresponding to the start spool rotation position obtained in step S104 to the stop spool rotation position obtained in step S109. The calculation unit 133 calculates the winding distance based on the accumulated line length for each acquired spool rotation position. In this way, the calculation unit 133 can calculate the winding distance by accumulating the line length obtained from the line length/spool rotation position table using the start spool rotation position and the stop spool rotation position (an example of the rotational state of the spool 4). The starting spool rotation position and the stopping spool rotation position are obtained by rotating the spool 4 in response to pressing the upper switch portion 112a, and are therefore an example of the rotational state of the spool 4 from the start to the end of a series of operations of the spool 4.

Step S111: In response to the calculation of the reeling distance in step S110, the display control unit 134 displays the water depth difference based on the reeling distance calculated in step S110 in the speed/water depth difference area AR10, instead of the number of rotational speed stages. The water depth difference displayed in this manner indicates the difference between the water depth when the user begins pressing the upper switch unit 112a for electric manual jigging, and the water depth when the user releases the pressing of the upper switch unit 112a.

When displaying the water depth based on the reeling distance calculated in step S110, the display control unit 134 may round the calculated reeling distance to a predetermined number of decimal places, and use this rounded value as the water depth difference. This allows the water depth difference to be presented to the user using a practical and easy-to-read number of digits.

Step S112: If it is determined in step S101 that the pressing operation on the upper switch unit 112a has not been started, or if it is determined in step S102 that the first button 111-1 is in a pressed state, or after the processing of step S111, the spool drive control unit 132 determines whether or not the operation of pressing the lower switch unit 112b once has been performed. The operation of pressing the lower switch unit 112b once is an operation to instruct the execution of one automatic jigging operation.
If it is determined that the lower switch portion 112b has not been pressed once, the process returns to step S101.

Step S113: If it is determined that the lower switch section 112b has been pressed once, the spool drive control section 132 determines whether the first button 111-1 was pressed at the same time that the lower switch section 112b was pressed once.
If it is determined that the first button 111-1 is pressed, the drive control parameter is changed (decremented), but in the figure, the procedure for changing the drive control parameter is omitted for convenience, and the process returns to step S101. In this way, when the first button 111-1 is pressed, the spool drive control unit 132 does not accept the operation of pressing the lower switch unit 112b once as an operation to instruct the execution of an automatic jig operation.

Step S114: If it is determined that the first button 111-1 is not pressed, the calculation unit 133 obtains the initial spool rotation position corresponding to the timing when the lower switch unit 112b was pressed in step S112.

Step S115: If it is determined in step S109 that the first button 111-1 is not pressed, the spool drive control unit 132 drives and rotates the spool 4 in accordance with the drive control parameters included in the drive control information stored in the drive control information storage unit 141 and the duty ratio corresponding to the acceleration parameter value VA stored in the duty ratio storage unit 142. This executes one automatic jigging operation in response to the operation of pressing the lower switch unit 112b once.

The flowchart of FIG. 9 shows an example of the processing procedure for the spool drive control corresponding to the drive control parameters as step S115 of FIG.
Step S1101: The spool drive control unit 132 acquires from the duty ratio storage unit 142 the initial duty ratio corresponding to the currently set acceleration parameter value VA.
Step S1102: The spool drive control unit 132 starts driving the motor 8 using the acquired initial duty ratio. As shown in Figures 4A and 4B, the driving of the motor 8 starts at time t0, and the spool 4 starts rotating at time t1 after a time lag.
Step S1103: When the motor 8 starts to be driven in step S1102, the time measurement unit 135 starts to measure the drive duration T.

Step S1104: The spool drive control unit 132 determines whether the currently measured drive duration T is equal to or greater than the drive time parameter value VT. In other words, the spool drive control unit 132 determines whether the value of the elapsed time from the timing at which drive of the motor 8 was started in step S1102 has reached the drive time parameter value VT.

Step S1105: If it is determined that the drive duration T has not reached the drive time parameter value VT, the spool drive control unit 132 determines whether the currently detected spool rotation speed vsp has reached the target rotation speed vtg.
If it is determined that the spool rotation speed vsp has not reached the target rotation speed vtg, the process returns to step S1104.

Step S1106: When the spool rotation speed vsp reaches the target rotation speed vtg, the spool drive control unit 132 performs constant speed control so that the spool rotation speed vsp remains at the target rotation speed vtg. At this time, the spool drive control unit 132 controls the duty ratio of the motor drive signal so that the spool rotation speed vsp becomes the target rotation speed vtg. After processing step S1106, processing returns to step S1104.

Step S1107: If it is determined in step S1104 that the drive duration T has reached the drive time parameter value VT, the spool drive control unit 132 stops motor drive. After processing step S1107, the process proceeds to step 116 in FIG. 8. Note that the time measurement unit 135 may stop measuring the drive duration T and reset the measured drive duration T in response to determining in step S1104 that the drive duration T has reached the drive time parameter value VT.

Returning to the explanation of FIG.
Step S116: The calculation unit 133 acquires the spool rotation position (stopped spool rotation position) corresponding to when the drive of the spool 4 is stopped by stopping the motor drive in step S110.

Step S117: The calculation unit 133 calculates the reeling distance caused by the rotation of the spool 4 as an automatic jigging operation in response to the current pressing operation on the lower switch unit 112b.
Step S118: The display control unit 134 displays the water depth difference based on the reeling distance calculated in step S117 in the speed and water depth difference area AR10. After the process of step S118, the process returns to step S101.

The depth difference displayed in steps S111 and S118 may be erased in response to a predetermined trigger. For example, the display control unit 134 may erase the display of the depth difference in response to the passage of a predetermined time after displaying the depth difference in steps S111 and S118. In response to the erasure of the depth difference display, the speed/depth difference area AR10 may be switched to displaying a number of stages indicating the rotational speed of the spool 4 that is currently set.
Furthermore, after displaying the water depth difference in steps S111 and S118, the display control unit 134 may be triggered to erase the display when the upper switch unit 112a corresponding to the next electric manual jigging operation or the lower switch unit 112b corresponding to the automatic jigging operation is pressed. In other words, the display control unit 134 may erase the display of the water depth difference in response to an operation to start driving the next spool 4 for which the winding distance is to be calculated.

According to the configuration of this embodiment described above, electric jigging mode enables electric manual jigging by continuously pressing the upper switch unit 112a, and automatic jigging by pressing the lower switch unit 112b once. As a fishing method, electric manual jigging and automatic jigging each correspond to one jerk. In this embodiment, each time one jerk is performed, the water depth difference of the rig corresponding to the reeling of the fishing line with one jerk is displayed on the display unit 102. The displayed water depth difference is expressed, for example, as a numerical value in meters up to a specified number of decimal places. This allows the user to accurately grasp how much the water depth of the rig has changed (become shallower) in response to one jerk performed in electric jigging mode. For example, the water depth area AR20 of the display unit 102 displays the water depth of the rig. The user can determine the difference in water depth corresponding to one jerk by subtracting the water depth displayed in the water depth area AR20 after performing one jerk from the water depth displayed in the water depth area AR20 before performing one jerk. However, in this case, the user must remember the water depth before and after performing one jerk and then perform the calculation themselves, which is not quick or accurate. In contrast, with this embodiment, the user can quickly and accurately determine the difference in water depth corresponding to one jerk.

<Modification>
Modifications of this embodiment will be described below. The modifications described below may be combined as appropriate.

[First Modification]
In the above embodiment, the electric fishing reel 1 is configured to display the water depth difference when the rotation of the spool 4 is stopped during electric manual jigging in the electric jigging mode, or when the rotation of the spool 4 is stopped during automatic jigging. In other words, the electric fishing reel 1 of the above embodiment is configured to display the water depth difference when the series of operations from when the spool 4 starts to when it stops rotating (one jerk corresponding operation) is completed in the electric jigging mode.
In contrast to this, the electric fishing reel 1 of this modified example may be configured to display the water depth difference that changes in response to the reeling in of the fishing line while the spool 4 is performing one jerk corresponding operation in the electric jigging mode.
In the case of electric manual jigging, the calculation unit 133 of this modified example starts calculating the winding distance in response to the start of pressing the upper switch unit 112a and the start of rotation of the spool 4, and continues calculating the winding distance until the rotation of the spool 4 is stopped by the subsequent release of pressing the upper switch unit 112a. While the spool 4 is rotating in response to continued pressing of the upper switch unit 112a in electric manual jigging, the display control unit 134 displays the water depth difference based on the winding distance calculated by the calculation unit 133 as described above in the speed/water depth difference area AR10.
Furthermore, in the case of automatic jigging operation, the calculation unit 133 calculates the reeling distance while the lower switch unit 112b is pressed once and the spool 4 is rotated for a time period corresponding to the drive time parameter value VT. While the spool 4 is rotating in accordance with the automatic jigging operation as described above, the display control unit 134 displays the water depth difference based on the reeling distance calculated by the calculation unit 133 as described above in the speed/water depth difference area AR10.
The water depth difference value displayed while the electric manual jigging or automatic jigging operation is being performed as described above will change, for example, increasing from zero as the fishing line is reeled in by the rotation of the spool 4.
When displaying the water depth difference by changing the numerical value over time as in this modified example, the display control unit 134 may change the numerical value in units of a predetermined length, such as 0 m, 0.1 m, 0.3 m, etc. For example, if the calculation unit 133 is capable of calculating the reeling distance in centimeters, and the display control unit 134 simply displays the calculated reeling distance, the water depth difference may change minutely over a short period of time, making it difficult for the user to see. Therefore, by displaying the water depth difference so that it changes in units of a predetermined length as described above, the user can more easily grasp the value of the water depth difference that changes over time.

[Second Modification]
For example, after a predetermined line length (unit line length) corresponding to a unit number of rotations (unit number of rotations) of the spool 4 is determined, the calculation unit 133 may calculate the winding distance based on the unit line length and the number of rotations of the spool 4 detected by the rotation sensor 106 during a series of operations of the spool 4. In this way, the number of rotations of the spool 4 detected by the rotation sensor 106 during a series of operations of the spool 4 is also an example of the rotational state of the spool 4 from the start to the end of a series of operations of the spool 4.

[Third Modification]
The electric fishing reel 1 of this modification may display the time corresponding to the period during which the spool 4 performs a series of operations in the electric jigging mode, together with the water depth difference, on the display unit 102. The time displayed in this manner corresponds to the time it takes to perform one jerk (the required jerk time).
To display the time required for a jerk, the electric fishing reel 1 may display the length of time that one jerk-compatible operation has been performed when the spool 4 has completed one jerk-compatible operation in the electric jigging mode, or may display the time being measured while one jerk-compatible operation is being performed.
The display of the required jerk time may also be erased in response to the occurrence of a predetermined trigger, similar to the water depth difference.

[Fourth Modification]
The electric fishing reel 1 of this modified example may be configured to display the difference in water depth either in the case of electric manual jigging in the electric jigging mode or in the automatic jigging operation.
Similarly, the electric fishing reel 1 of this modified example may display the required jerk time of the third modified example in either the case of electric manual jigging in the electric jigging mode or in the automatic jigging operation.

[Fifth Modification]
The electric fishing reel 1 of this modified example may also display the water depth difference when the user is jerking the lure by operating the handle 3 (handle operation jigging) when the electric jigging mode is not set. In this case, the calculation unit 133 may calculate the reeling distance corresponding to the period from when the rotation of the spool 4 starts in response to the start of the operation to reel in the fishing line with the handle 3 until the rotation of the spool 4 stops, and the display control unit 134 may display the water depth difference based on the calculated reeling distance. Even in this modified example, the electric fishing reel 1 may display the water depth difference when the rotation of the spool 4 stops, or may display the water depth difference that changes as the fishing line is reeled in while the spool 4 is rotating.
Also, the required jerk time may be displayed during handle operation jigging.
Therefore, the configuration of this embodiment for displaying the water depth difference, the required jerk time, etc. can also be applied to non-electric fishing reels in which the spool is not driven by a motor.

[Sixth Modification]
In the above embodiment, the series of operations of the spool 4 that are the subject of calculation of the winding distance by the calculation unit 133 are the operations from the start to the stop of one rotation of the spool 4 corresponding to one jerk. However, the series of operations of the spool 4 that are the subject of calculation of the winding distance by the calculation unit 133 are not limited to the above-described operations of the spool 4. For example, the calculation unit 133 may calculate the winding distance for multiple consecutive operations from the start to the stop of rotation of the spool 4 corresponding to multiple consecutive jerks.
As a specific example, the electric fishing reel 1 can set drive control parameters for an automatic jigging operation, including a speed [SPEED], a drive time [DRIVE_TIME], and a stop time [STOP_TIME]. In response to an operation to start the automatic jigging operation, the electric fishing reel 1 rotates the spool 4 at the speed [SPEED] for the drive time [DRIVE_TIME], and stops the rotation of the spool 4 for the stop time [STOP_TIME] after the drive time [DRIVE_TIME] has elapsed. The electric fishing reel 1 stops the rotation of the spool 4 in response to an operation to end the automatic jigging operation. When such an automatic jigging operation is performed, the rotation of the spool 4 obtained from the operation to start the automatic jigging operation to the operation to end the automatic jigging operation may be considered to be the series of operations of the spool 4 that are the subject of calculation of the reeling distance.

[Seventh Modification]
In the above embodiment, the second button 111-2 and the third button 111-3 are used as an up button and a down button, respectively, for selecting a parameter to be changed and changing the parameter value of the drive control parameter to be changed.
However, the number of operators used to select a parameter to be changed or to change the parameter value of a drive control parameter to be changed is not limited to two, and may be, for example, one.
In the case where there is one operator, if the operator is a button, the selected parameter or parameter value to be changed may be changed cyclically each time the operator is pressed. Alternatively, if the operator is a lever or the like, the parameter or parameter value to be changed may be changed in a forward order in response to the lever being moved in one predetermined direction, and the parameter or parameter value to be changed may be changed in a reverse order in response to the lever being moved in the other predetermined direction.

[Eighth Modification]
In the above embodiment, the buttons 111 (first button 111-1, second button 111-2, and third button 111-3) are provided as physical controls. However, the buttons 111 may be controls that are images displayed on the display unit 102, which is a touch panel, for example.

In addition, a program for implementing the functions of the electric fishing reel 1 in the above embodiment may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be loaded into a computer system and executed to perform the processing of the electric fishing reel 1 described above. Here, "loading a program recorded on a recording medium into a computer system and executing it" includes installing the program on a computer system. The term "computer system" here includes hardware such as an OS and peripheral devices. The term "computer system" may also include multiple computer devices connected via a network, including communication lines such as the Internet, WAN, LAN, and dedicated lines. The term "computer-readable recording medium" refers to portable media such as floppy disks, optical magnetic disks, ROMs, and CD-ROMs, as well as storage devices such as hard disks built into a computer system. Thus, a recording medium storing a program may be a non-transitory recording medium such as a CD-ROM. Recording media also include internal or external recording media accessible from a distribution server for distributing the program. The program code stored on the distribution server's recording medium may be different from the program code executable on a terminal device. In other words, the format in which the program is stored on the distribution server does not matter as long as it can be downloaded from the distribution server and installed in a form that is executable on a terminal device. The program may be divided into multiple parts that are downloaded at different times and then combined on the terminal device, or each of the divided programs may be distributed by a different distribution server. Furthermore, the term "computer-readable recording medium" also includes a storage medium that stores a program for a certain period of time, such as volatile memory (RAM) within a computer system that acts as a server or client when a program is transmitted over a network. The program may also be a program that realizes some of the functions described above. Furthermore, the program may be a so-called differential file (differential program) that can realize the functions described above in combination with a program already stored on the computer system.
