Description

The present invention relates to a parameter setting device for an electric fishing reel, an electric fishing reel equipped with the same, a parameter setting method, and a parameter setting program.

For automatic jerk fishing, the user creates a desired operation pattern by appropriately combining the spool drive operation time, operation stop time, operation speed, amount of fishing line let out, and amount of fishing line reeled in, and inputs and stores the operation pattern in a storage means. When an operation pattern is selected, a control means drives the spool according to the operation pattern. Electric fishing reels are known (see, for example, Patent Document 1).

Patent No. 2839297

In electric fishing reels like the one described above, when the spool starts to rotate according to the operating pattern, the motor is driven with a duty ratio that corresponds to the set operating speed, for example. As a result, for example, the behavior of the fishing line reeling from when the spool starts to rotate until it reaches the target speed may not be in line with the user's intention.

The present invention was made in consideration of these circumstances, and aims to make the automatic baiting action performed by rotating the spool closer to the user's intentions.

One aspect of the present invention for solving the above-mentioned problems is a parameter setting device for an electric fishing reel that includes a parameter setting unit that changes, in response to an operation, a parameter for the acceleration of the rotation of the spool during an initial period from when the rotational drive of the spool begins until when the spool reaches a predetermined rotational speed, among a plurality of predetermined parameters for giving a predetermined rotational state to a spool driven in rotation by a motor.
According to the above configuration, the acceleration parameter during the initial period from when the spool starts to rotate until it reaches a predetermined rotation speed can be changed according to the user's operation. By changing the acceleration parameter in this way, it is possible to change the initial jerk in the automatic jigging operation. This makes it possible to make the automatic jigging operation performed by rotating the spool closer to the user's intention.

Moreover, one aspect of the present invention is the above-mentioned parameter setting device, which includes a spool drive control unit that sets the duty ratio of the pulse width per period of the motor drive signal applied to the motor during the initial period from when the spool starts to rotate until it reaches a predetermined rotation speed, based on the value of the acceleration parameter.
According to the above configuration, the acceleration can be changed by changing the duty ratio of the pulse width of the motor drive signal.

Moreover, one aspect of the present invention is the above-mentioned parameter setting device, wherein the spool drive control unit changes the duty ratio in a predetermined pattern in accordance with the passage of time in the initial movement period, in correspondence with the acceleration parameter.
According to the above configuration, by changing the duty ratio over time, it is possible to diversify the variation in the rotation speed of the spool during the initial movement period, and also to bring the rotation speed closer to a desired change.

Another aspect of the present invention is the above-mentioned parameter setting device, wherein the parameter setting unit changes the acceleration parameter by selecting one acceleration parameter from among a plurality of acceleration parameters corresponding to each of a plurality of stages in response to an operation.
According to the above configuration, the user can easily set the acceleration parameter by selecting one step from a plurality of steps, rather than by using a numerical value corresponding to the acceleration, for example.

Another aspect of the present invention is an electric fishing reel equipped with the above-mentioned parameter setting device.

Another aspect of the present invention is a parameter setting method for an electric fishing reel, which includes a parameter setting step for changing, in response to an operation, a parameter for the acceleration of the rotation of the spool during the initial period from when the spool starts to rotate until it reaches a predetermined rotation speed, among a plurality of predetermined parameters for giving a predetermined rotation state to a spool driven by a motor.

Another aspect of the present invention is a parameter setting program for causing a computer serving as a parameter setting device for an electric fishing reel to function as a parameter setting unit that changes, in response to an operation, a parameter for the acceleration of the rotation of the spool during the initial period from when the spool starts to rotate until it reaches a predetermined rotation speed, among a plurality of predetermined parameters for giving a predetermined rotation state to a spool driven by a motor.

As described above, the present invention has the effect of making the automatic baiting action performed by rotating the spool more in tune with the user's intentions.

<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 spool drive control refers to control related to the drive of the spool, and includes control for rotating the spool, control for stopping the rotation of the spool, control for changing the rotation speed of the spool, etc.
In the following description, the "drive" of the spool may be described as "rotation drive" for the purpose of clarifying that it provides a rotational motion.
In the following description, a dual-bearing electric fishing reel 1 is used as an example. In addition, in Figs. 1 and 2, the scale of each component may be appropriately changed as necessary to make each 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 of this embodiment. The electric fishing reel 1 of this embodiment mainly comprises a reel body 2 that can be attached to a fishing rod (not shown), a handle 3 that is attached rotatably about a handle axis O1 relative to the reel body 2, a spool 4 that can be rotatable about a spool axis O2 parallel to the handle axis O1 relative to the reel body 2 and around which a 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 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 let out 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 viewpoint of the electric fishing reel 1 as seen from the rear side (the angler's side). Thus, Fig. 1 is a perspective view of the electric fishing reel 1 as seen obliquely 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 (for example, aluminum die-cast). The main body frame 10 includes a first side wall 11 and a second side wall 12 arranged to face 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 disposed on the left side (LH) of the spool 4. In contrast, the second side wall 12 is a right side wall disposed on the right side (RH) of the spool 4. The handle 3 is disposed further to the right (RH) of the second side wall 12, and is attached to the main body frame 10 by utilizing 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 from the first side wall 11 in order to mount the connector portion 23 and the like.

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 to each other via the connecting member 13.
At the center of the connecting member 13 in the left-right direction L1, a mounting leg piece 14 for mounting 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 tube 7 that 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 includes a first side cover 21 that is combined with the main frame 10 to cover the first side wall 11, in which the opening of the motor housing tube 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 toward the left side (LH) and is fixed to the first side wall 11 by, for example, screws.
The second side cover 22 is formed so as to bulge toward the right side (RH) and is fixed to the second side wall 12 by, for example, screws.
A power reel cord for supplying power from an external power source or a connector section 23 for connecting a portable battery is attached to the lower front portion of the second side cover 22 with its connecting end (not shown) facing downward. Each drawing shows the connecting end protected by a protective cap 24.

The front cover 30 is combined with the main body frame 10 so as to cover the front part of the main body frame 10 from the front. Specifically, the front cover 30 is combined with the front parts 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 fixed to the first side wall 11 and the second side wall 12, for example, by 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 upper part of the main body frame 10 configured as described above. The counter case 40 is disposed between the first side wall 11 and the second side wall 12 and is fixed to the upper part of the first side wall 11 and the upper part of the second side wall 12, for example, by screws.

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

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

The operation unit 101 is a portion where the user operates buttons. In the example shown in the figure, the operation unit 101 has three buttons arranged as buttons for operation: a first button 111-1 (an example of a first operator), a second button 111-2 (an example of a second operator), and a third button 111-3 (an example of a second operator). In the following explanation, when there is no particular distinction 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 arranged to the left of the positions at which 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, and the like, providing a familiar operational feel to the user.

The operating unit 101 is also provided with a winding switch 112. The winding switch 112 is an operator that rotates the spool 4 to 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, and can be operated by pressing down the upper switch portion 112a and the lower switch portion 112b.

The display unit 102 is a portion 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 is provided as the display unit 102, but examples include a liquid crystal display device and an organic EL display device.

Returning to Fig. 1 and Fig. 2, the explanation is given. The handle 3 is used for manually reeling in the fishing line. The handle 3 is disposed to the right (RH) of the main body frame 10 and the first side cover 21. The handle 3 includes a handle shaft portion 50 disposed rotatably about a handle axis O1, a handle arm 51 non-rotatably attached to the handle shaft portion 50, and a handle knob 52 attached to the end of the handle arm 51 rotatably about an axis parallel to the handle axis O1.
A drag 53 (star drag) arranged coaxially with the handle axis O1 is provided 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 contributing to preventing the fishing line from breaking.

The rotational torque from the handle 3 thus configured is directly transmitted to the spool 4 via a rotation transmission mechanism (not shown) when the clutch mechanism 6 is in a clutch-on state.
In this embodiment, the so-called single handle type in which the handle knob 52 is attached to one end of the handle arm 51 is taken as an example for explanation, but the present invention is not limited to this case. For example, the electric fishing reel 1 may be a so-called double handle type in which the handle knob 52 is 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 disposed 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 includes 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 the 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 the 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, and the spool 4 can be rotated about the spool axis O2. This allows manual winding.
When the clutch mechanism 6 is in the clutch-off state, the rotational torque caused by the rotational operation 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 disposed 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 about the spool axis O2.

The rotation transmission mechanism is configured to transmit the 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 rotational operation 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 for winding the fishing line evenly around the spool 4 without bias.

Furthermore, when the motor is driven while the clutch mechanism 6 is in the clutch-on state, the rotation transmission mechanism is capable of transmitting the rotation torque associated with the drive of the motor to the spool 4. This enables automatic winding operation. The rotation transmission mechanism transmits the rotation torque to the spool 4 while decelerating the rotation of the motor.

[About electric jigging mode]
When the electric jigging mode is on, the electric fishing reel 1 of this embodiment can execute 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 an 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 starts, and the fishing line starts to be wound up. As long as the user continues to press the upper switch portion 112a, the rotation of the spool 4 continues, and the fishing line continues to be wound up. When the user releases the pressure on the upper switch portion 112a, the rotation of the spool 4 stops, and the fishing line stops being wound up.
In the electric jigging mode, when the upper switch portion 112a is first pressed, the fishing line is wound up at a spool rotation speed (intermediate winding speed) that is less than the preset maximum speed. If the upper switch portion 112a is subsequently pressed further while continuing to be pressed, the fishing line is wound up at a winding speed that has increased to the maximum.

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 lure action (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 preset drive control information, and the fishing line is reeled in.

The drive control parameters (one example of a plurality of predetermined parameters for giving a predetermined rotational state to a spool rotated by a motor) that constitute the drive control information corresponding to the automatic jig operation of this embodiment are the winding length [LENGTH], speed [SPEED], and acceleration [ACCEL].
The reel length [LENGTH] is the length of fishing line reeled 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 of the winding length [LENGTH] (winding length parameter value VL), the parameter value of the speed [SPEED] (speed parameter value VS), and the parameter value of the acceleration [ACCEL] (acceleration parameter value VA) can each be changed by the user through operations as described below.

The winding length parameter value VL may be a value corresponding to a length in meters, 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 of which corresponds to a predetermined speed.

The acceleration parameter value VA may be a value according 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 corresponding to a predetermined acceleration as a high acceleration, VA_M corresponding to a predetermined acceleration as a medium acceleration, and VA_L corresponding 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 in a relatively small number of stages, such as three stages, so that the user can clearly understand the difference in the behavior of the spool rotation 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 jigging operation by setting the drive control parameters of the winding length [LENGTH], speed [SPEED], and acceleration [ACCEL]. In the figure, the horizontal axis represents time and the vertical axis represents rotation speed.
In the same figure, there are shown 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. That is, the electric fishing reel 1 starts applying a voltage (motor drive signal) for driving the motor from time t0. However, even if the electric fishing reel 1 starts rotating the spool 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, which starts rotating at time t1, increases its rotation speed at an acceleration according to the parameter value of the set acceleration parameter value VA_H. Then, 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. After time t2(1), the spool 4 is controlled to rotate at a constant rotation speed corresponding to the speed parameter value VS.

The electric fishing reel 1 measures the length of fishing line being wound onto the spool 4 after the spool 4 starts to rotate at time t1. Then, when the length of the wound fishing line reaches the winding length VL at time t3, the supply of current to the motor is stopped to stop the rotation of the spool 4.

Even if the supply of current is stopped, the motor does not stop immediately due to inertia, but rotates a certain amount before stopping, a phenomenon called overrun occurs. In the example in the figure, the rotational speed of spool 4 is decelerated during the period when overrun occurs from time t3 onwards, and rotation of spool 4 stops at time t4.

Moreover, when the acceleration parameter value VA_M is set, the spool behavior GM is as follows.
In this case as well, at time t0, the application of a motor drive signal for starting the rotation drive of the spool is started in response to the user pressing the lower switch portion 112b of the winding switch 112 once. Then, at time t1, which is a certain period of time after time t0, the spool 4 starts to rotate.

The spool 4, which starts rotating at time t1, increases its rotation speed at an acceleration according to the parameter value of 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 length of the wound fishing line reaches the winding length VL, 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.

Moreover, when the acceleration parameter value VA_L is set, the spool behavior GL is as follows.
In this case, when the user presses the lower switch portion 112b of the winding switch 112 once at time t0, the spool 4 starts to rotate at time t1, which is a certain time lag (delay) from time t0 when the application of the motor drive signal began.

The spool 4, which starts rotating at time t1, increases its rotation speed at an acceleration according to the parameter value of 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). After time t2(3), 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 length of the wound fishing line reaches the winding length VL, 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 starts to rotate may differ depending on the acceleration parameter value VA. However, for the sake of clarity, the figure shows an example in which the times t1 of the spool behaviors GH, GM, and GL are the same regardless of the acceleration parameter value VA.
Furthermore, depending on the acceleration parameter value VA, the time t3 at which the length of the wound fishing line reaches the reeled length VL may differ, and the time t4 at which the spool 4 stops rotating may also differ. However, for the sake of ease of illustration, the figure shows an example in which the times t3 and t4 of the spool behaviors GH, GM, and GL are the same regardless of the acceleration parameter value VA.

The electric fishing reel 1 of this embodiment drives the motor by PWM (Pulse Width Modulation) control to rotate the spool 4. Therefore, when driving the motor, the electric fishing reel 1 sets the duty ratio of the pulse width per period for 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 each of 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 rotation speed of the spool 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 is started. As a result, the spool 4 starts rotating at time t1 after a time lag, and the rotation speed increases due to acceleration according 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 speed at the target rotation speed vtg.
After time t2(1), feedback control is performed to detect the rotation speed of the spool 4 and change the constant-speed duty ratio ds so that the detected rotation speed becomes the target rotation speed vtg. In the figure, for the sake of clarity, the constant-speed duty ratio ds is shown as being constant and does not change according to the progress of the event, but the constant-speed duty ratio ds fluctuates due to feedback control. For example, the constant-speed duty ratio ds for maintaining the target rotation speed vtg fluctuates due to the condition of the tackle in the water, the line winding length per one rotation of the spool 4 according to the line winding diameter, and the like.

However, the range of the constant-speed duty ratio ds that can be controlled corresponding to each stage of the speed parameter value VS is determined in advance. By determining 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 become 100% even if a high load is applied to the motor at a low speed setting. This makes it possible to avoid a situation where the actual winding speed does not change even when the speed parameter value VS is changed.

For example, in a constant tension mode where 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 the constant tension mode, the tension changes depending on the line winding diameter on the spool 4, so the duty ratio is controlled to change in response to such tension changes.

After that, at time t3, when the length of the reeled fishing line reaches the reeled length VL, application of the motor drive signal is stopped.

As for the duty ratio transition DM corresponding to the spool behavior GM, first, from time t0, the application of the motor drive signal with the initial duty ratio dm corresponding to the acceleration parameter value VA_M is started. Since the initial duty ratio dm corresponds to a medium acceleration, it is smaller than the initial duty ratio dh corresponding to the acceleration parameter value VA_H corresponding to a high acceleration. In this case, the acceleration of the rotation of the spool 4 from time t1 onwards is lower than that in the case of the initial duty ratio dh corresponding to a high acceleration. Then, from time t(2) onwards when the target rotation speed vtg is reached, the constant speed corresponding duty ratio ds is maintained. Then, at time t3 when the length of the reeled fishing line reaches the reeled length VL, the application of the motor drive signal is stopped.

As for the duty ratio transition DL corresponding to the spool behavior GL, first, from time t0, the application of the motor drive signal with the initial duty ratio dl corresponding to the acceleration parameter value VA_L is started. Since 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 that 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. Then, at time t3 when the length of the reeled fishing line reaches the reeled length VL, the application of the motor drive signal is stopped.

As can be seen from the figure, the electric fishing reel 1 changes the duty ratio of the motor drive signal over time according to the parameter values of the drive control parameters (winding length parameter value VL, speed parameter value VS, acceleration parameter value VA), thereby rotating the spool 4 in response to the automatic lure operation.

As a drive control parameter, instead of setting the acceleration [ACCEL], for example, the rotation of the spool 4 may be started from the beginning with an acceleration according 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 in the jigging operation depending on the situation may lead to a catch. Therefore, by providing a drive control parameter for acceleration [ACCEL] as in this embodiment, the sharpness of the initial jerk in the jigging operation can be changed according to the user's intention in the automatic jigging operation.

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 each parameter value of the drive control parameters, as shown in FIG. 4(B). This changes the rotation speed of the spool 4 as shown in FIG. 4(A), and one automatic jigging operation is performed. By winding up the fishing line at a winding speed that changes according to the rotation speed of the spool 4, an automatic jigging movement is obtained.

[Setting drive control parameters for automatic jogging]
Next, an example of the procedure for setting each parameter value (winding length parameter value VL, speed parameter value VS, acceleration parameter value VA) of the drive control parameters (winding length [LENGTH], speed [SPEED], and acceleration [ACCEL]) corresponding to the automatic jigging operation will be described. In this embodiment, the setting operation of the drive control parameters corresponding to the automatic jigging operation can be performed with the electric jigging mode turned on.
In this embodiment, setting of a drive control parameter includes selecting a drive control parameter whose parameter value is to be changed, and changing the parameter value of the drive control parameter selected as the parameter to be changed.

5 shows an example of the display on the display unit 102 when the electric jigging mode is on. In the display unit 102 in the figure, a speed area AR10, a water depth area AR20, and a parameter display area AR30 are arranged.
The speed area AR10 is an area in which the currently set rotation speed of the spool 4 is displayed in stages.
The water depth area AR20 is an area that displays the water depth at which the fishing tackle is currently located.

The parameter display area AR30 is an area in which the currently set parameter values for each drive control parameter are displayed. The parameter display area AR30 includes a winding length display area AR31-1, a speed display area AR31-2, and an acceleration display area AR31-3. When no particular distinction is required, the winding length 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 winding length display area AR31-1 is an area in which the currently set winding length parameter value VL is displayed.
The speed display area AR31-2 is an area in which 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.

In the figure, an example is shown in which the winding length display area AR31-1 is highlighted in the parameter display area AR30. The state in which the winding length display area AR31-1 is highlighted in this manner indicates that, of the drive control parameters (winding length [LENGTH], speed [SPEED], and acceleration [ACCEL]), the winding length [LENGTH] has been selected as the parameter value to be changed.
The parameter display area AR30 is in a state where one of the winding length display area AR31-1, the speed display area AR31-2, and the acceleration display area AR31-3 is highlighted depending on which of the drive control parameters (winding length [LENGTH], 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 target is displayed with its light and dark colors inverted 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 target may be made thicker, or in the case of a color display, the background color or text color may be changed.

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

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

When the user wants to increase the winding length parameter value VL, he or she 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 winding length parameter value VL is incremented.
To decrease the winding length parameter value VL, the user 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 winding length parameter value VL is decremented.

When the user presses and holds the second button 111-2, the winding length parameter value VL may be continuously incremented until the second button 111-2 is released. When the user presses and holds the third button 111-3, the winding length parameter value VL may be continuously decremented until the third button 111-3 is released.

The winding length display area AR31-1 displays the winding length parameter value VL changed by the above operation. This allows the user to confirm the winding length parameter value VL changed by their own operation.

When the user changes the winding length parameter value VL to the desired value as described above, the user releases the pressure on the first button 111-1 that has been continued up until that point. This causes the electric fishing reel 1 to not accept any operation on the second button 111-2 and the third button 111-3 that change the winding length parameter value VL. The electric fishing reel 1 also finalizes the winding length parameter value VL as the value that was displayed in the winding length 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 lure action may not be performed even if the user operates the lower switch portion 112b.
This makes it possible to prevent 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 for which the 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 level above the individual parameter display area AR31 that was previously highlighted 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 display may cycle to highlight the bottommost individual parameter display area AR31.

In addition, 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 target for parameter value change.

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 winding length [LENGTH], speed [SPEED], and acceleration [ACCEL].
In addition, the operation of changing the parameter value of the drive control parameter is performed while the electric jigging mode is on. In other words, the user can change the parameter value of the drive control parameter in the electric jigging mode without changing the setting mode for changing the drive control parameter from the electric jigging mode. This allows the user to quickly change the drive control parameter of the automatic jigging operation even during actual fishing.

The operation of changing the parameter value and the operation of selecting the drive control parameter for which the 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 of changing the parameter value and the operation of selecting the 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 electric fishing reel]
An example of the functional configuration of the electric fishing reel 1 will be described with reference to Fig. 6. In this figure, the same parts as those in Figs. 1 and 2 are given the same reference numerals and the description thereof will be omitted as appropriate.
The electric fishing reel 1 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, the motor 8, the 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 central processing unit (CPU) included in the electric fishing reel 1 executing a program.
The control unit 103 includes a parameter setting unit 131 and a spool drive control unit 132 .
The parameter setting unit 131 sets the parameter values of the drive control parameters in response to an 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 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, and an intermediate winding speed memory unit 143.

The drive control information storage unit 141 stores drive control information. The drive control information is information used to drive and control the spool 4 during automatic jigging operations. As described above, the drive control information includes drive control parameters such as winding length [LENGTH], 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, dl corresponding to each of the acceleration parameter values VA_H, VA_M, VA_L.
When 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 the electric jigging mode. The intermediate winding speed can be set arbitrarily within a range lower than the maximum rotation speed of the spool 4, for example, by the user performing an operation.

The motor drive circuit 105 drives the motor 8 according to 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 using PWM control.

[Example of processing procedure]
An example of a processing procedure for setting drive control parameters corresponding to an automatic jigging operation in the electric fishing reel 1 will be described with reference to the flowchart of Fig. 7. The processing in Fig. 7 is executed when the electric jigging mode is turned on.

Step S101: The parameter setting unit 131 in the electric fishing reel 1 determines whether or not the second button 111-2 has been pressed once.

Step S102: When the parameter setting unit 131 determines that a single pressing operation has been performed on the second button 111-2, it determines whether or not the first button 111-1 was in a pressed state when the single pressing operation of the second button 111-2 was performed.

Step S103: If it is determined in step S102 that the first button 111-1 is in a pressed state, the parameter setting unit 131 increments the current parameter value of the drive control parameter currently selected as the target for change.
The parameter setting unit 131 may store the incremented parameter value as a provisional value in, for example, a random access memory (RAM) or a register.
Furthermore, the parameter setting unit 131 executes display control so that the parameter value changed by increment is displayed in the corresponding individual parameter display area AR31.
If the current parameter value is already the maximum value when step S103 is reached, the process of step S103 may be skipped. In this case, the second button 111-2 has been pressed once, but the parameter value remains at the maximum value. Alternatively, if the current parameter value is already the maximum value when step S103 is reached, the parameter value may be changed to the minimum parameter value in a circular manner.

Step S104: If it is determined in step S102 that the first button 111-1 is not in a pressed state, the parameter setting unit 131 changes the drive control parameter selected as the object to be changed.
A selection order is set for the drive control parameters. In step S104, the parameter setting unit 131 selects, as a new drive control parameter to be changed, a drive control parameter whose selection order is one step reverse to the drive control parameter that has been selected as the drive control parameter to be changed up until now.
Specifically, the selection order of the drive control parameters may be set in the order of winding length [LENGTH], speed [SPEED], and acceleration [ACCEL], in accordance with the order of winding length display area AR31-1, speed display area AR31-2, and acceleration display area AR31-3 illustrated in Fig. 5. In this case, for example, if the speed [SPEED] has been selected as the item to be changed, then in step S104, winding length [LENGTH] will be newly selected as the item to be changed.
In addition, when step S104 is reached while the winding length [LENGTH], which is the first item in the selection order, is selected, the parameter setting unit 131 may leave the selection of the drive control parameter at the winding length [LENGTH] without changing it, or may cycle through the selection order and newly select the acceleration [ACCEL], which is the last item in the selection order (the third item).

Step S105: If it is determined in step S101 that the second button 111-2 has not been pressed once, or after the processing of steps S103 and S104, the parameter setting unit 131 determines whether or not the third button 111-3 has been pressed once.

Step S106: When the parameter setting unit 131 determines that one pressing operation has been performed on the third button 111-3, it determines whether or not the first button 111-1 was in a pressed state when this single pressing operation of the third button 111-3 was performed.

Step S107: If it is determined in step S106 that the first button 111-1 is in a pressed state, the parameter setting unit 131 decrements the current parameter value of the drive control parameter currently selected as the parameter to be changed.
The parameter setting section 131 may store the decremented parameter value as a provisional value in, for example, a RAM or a register.
Furthermore, the parameter setting unit 131 executes display control so that the parameter value changed by decrement is displayed in the corresponding individual parameter display area AR31.
If the current parameter value is already the minimum value when the process reaches step S107, the process of step S107 may be skipped. In this case, the third button 111-3 has been pressed once, but the parameter value remains at the minimum. Alternatively, if the current parameter value is already the minimum value when the process reaches step S103, the parameter value may be changed to the maximum parameter value in a circular manner.

Step S108: If it is determined in step S106 that the first button 111-1 was not pressed, the parameter setting unit 131 selects as a new drive control parameter to be changed the drive control parameter that is one step forward in the selection order from the drive control parameter that was previously selected as the drive control parameter to be changed.
Note that when the process reaches step S108 while the last (third) acceleration [ACCEL] in the selection order is selected, the parameter setting unit 131 may leave the selection of the drive control parameter at acceleration [ACCEL] without changing it, or may cycle through the selection order and newly select the winding length [LENGTH] which is the first parameter in the selection order.

Step S109: If it is determined in step S105 that a single pressing operation has not been performed on the third button 111-3, or after the processing of steps S107 and S108, the parameter setting unit 131 determines whether or not the first button 111-1 has changed from a previously pressed state to a released state.
If it is determined that first button 111-1 has not been released, the process returns to step S101.

Step S110: When it is determined in step S109 that the first button 111-1 has been released, the parameter setting unit 131 updates the parameter value of the drive control parameter currently selected as the target for change, among the drive control parameters stored in the drive control information storage unit 141, with the parameter value currently stored as the provisional value. This determines the parameter value of the drive control parameter changed in step S103 or step S107.
When it is determined in step S109 that the pressure on first button 111-1 has been released, if the parameter value stored in drive control information storage unit 141 is the same as the parameter value displayed in individual parameter display area AR31, step S110 may be skipped. After the process of step S110, the process returns to step S101.

Figure 8 shows an example of the processing procedure when the electric fishing reel 1 increments the acceleration parameter value VA in response to the acceleration [ACCEL] being selected as the target to be changed in step S103 of Figure 7.

Step S1301: The parameter setting unit 131 determines whether the current acceleration parameter value VA is [VA_H].
If it is determined that the acceleration parameter value VA is [VA_H], the process in FIG.
If it is determined that the acceleration parameter value VA is [VA_H], the parameter setting section 131 may cyclically change the acceleration parameter value VA to [VA_L].

Step S1302: If it is determined that the acceleration parameter value VA is not [VA_H], the parameter setting unit 131 determines whether the current acceleration parameter value VA is [VA_M].

Step S1303: If it is determined that the current acceleration parameter value VA is [VA_M], the parameter setting unit 131 changes the acceleration parameter value VA to [VA_H]. In other words, the parameter setting unit 131 increments the acceleration parameter value VA.

Step S1304: If it is determined in step S1302 that the acceleration parameter value VA is not [VA_M], the current acceleration parameter value VA is [VA_L]. Therefore, the parameter setting unit 131 increments the acceleration parameter value VA by changing it to [VA_M].

Figure 9 shows an example of the processing procedure when the electric fishing reel 1 decrements the acceleration parameter value VA in response to the acceleration [ACCEL] being selected as the object to be changed in step S107 of Figure 7.

Step S1701: The parameter setting unit 131 determines whether the current acceleration parameter value VA is [VA_L].
If it is determined that the acceleration parameter value VA is [VA_L], the process in FIG.
If it is determined that the acceleration parameter value VA is [VA_L], the parameter setting section 131 may cyclically change the acceleration parameter value VA to [VA_H].

Step S1702: If it is determined that the acceleration parameter value VA is not [VA_L], the parameter setting unit 131 determines whether the current acceleration parameter value VA is [VA_M].

Step S1703: If it is determined that the current acceleration parameter value VA is [VA_M], the parameter setting unit 131 changes the acceleration parameter value VA to [VA_L]. In other words, the parameter setting unit 131 decrements the acceleration parameter value VA.

Step S1704: If it is determined in step S1702 that the acceleration parameter value VA is not [VA_M], the current acceleration parameter value VA is [VA_H]. Therefore, the parameter setting unit 131 decrements the acceleration parameter value VA to change it to [VA_M].

An example of a process procedure that the electric fishing reel 1 executes in response to an operation on the winding switch 112 when the electric jigging mode is on will be described with reference to the flowchart of FIG.
Step S201: 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 is being pressed, the spool 4 is driven to rotate and the fishing line is wound up.

Step S202: When it is determined that the upper switch portion 112a has been started to be pressed, the spool drive control portion 132 determines whether or not the first button 111-1 is being pressed in addition to the pressing of the upper switch portion 112a.
If it is determined that the first button 111-1 is not pressed, the process proceeds to step S208. In this case, step S203, which will be described next, is skipped, and the spool 4 is not rotated, so that the fishing line is not wound up. 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 S203: If it is determined that the first button 111-1 is not pressed, 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 S204: After starting drive control to rotate the spool 4 at the intermediate winding speed in step S203, the spool drive control unit 132 determines whether the pressing force detected by the upper switch unit 112a in the pressed state has changed to increase.

Step S205: If it is determined that the pressing force has changed to increase, 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 process of step S205 may be skipped.

Step S206: The spool drive control unit 132 determines whether or not 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 S204.

Step S207: If it is determined in step S206 that the pressed state of the upper switch unit 112a has been released, the spool drive control unit 132 stops the rotation drive of the spool 4.

Step S208: If it is determined in step S201 that the pressing operation on the upper switch unit 112a has not been started, or if it is determined in step S202 that the first button 111-1 is not pressed, or after the processing of step S207, the spool drive control unit 132 determines whether or not the lower switch unit 112b has been pressed once. The operation of pressing the lower switch unit 112b once is an operation to instruct the execution of one automatic fishing operation.
If it is determined that the lower switch portion 112b has not been pressed once, the process returns to step S201.

Step S209: If it is determined that the lower switch section 112b has been pressed once, the spool drive control section 132 determines whether or not the first button 111-1 was pressed in addition to the operation of pressing the lower switch section 112b once.
If it is determined that the first button 111-1 is pressed, the process returns to step S201. In other words, while 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 lure action.

Step S210: If it is determined in step S209 that the first button 111-1 is not pressed, the spool drive control unit 132 drives the spool 4 to rotate 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 lure action in response to the operation of pressing the lower switch unit 112b once. After the process of step S210, the process returns to step S201.

The flowchart in FIG. 11 shows an example of a processing procedure for the spool drive control corresponding to the drive control parameters as step S210 in FIG.
Step S2101: The spool drive control unit 132 acquires from the duty ratio storage unit 142 an initial duty ratio corresponding to the currently set acceleration parameter value VA.
Step S2102: The spool drive control unit 132 starts driving the motor 8 with the obtained initial duty ratio. As shown in Fig. 4A and Fig. 4B, in response to the start of driving the motor 8 at time t0, the spool 4 starts rotating at time t1 after a time lag.
Step S2103: When the motor 8 starts to be driven in step S2102, the spool drive control unit 132 starts to detect the length of the fishing line being wound up in response to the rotation of the spool 4 (actual wound-up length L).

Step S2104: The spool drive control unit 132 determines whether the currently detected actual winding length L is equal to or greater than the winding length parameter value VL. In other words, the spool drive control unit 132 determines whether the actual winding length L has reached the winding length parameter value VL.

Step S2105: If it is determined that the actual winding length L has not reached the winding length parameter value VL, the spool drive control unit 132 determines whether the currently detected spool rotational speed vsp has reached the target rotational 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 S2104.

Step S2106: When the spool rotation speed vsp reaches the target rotation speed vtg, the spool drive control unit 132 executes constant speed control so that the spool rotation speed vsp is maintained 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 the processing of step S2106, the process returns to step S2104.

Step S2107: If it is determined in step S2104 that the actual winding length L has reached the winding length parameter value VL, the spool drive control unit 132 stops the motor drive.

<Modification>
A modification of this embodiment will now be described.
[First Modification]
FIG. 4A shows an image of the spool rotation speed increasing at a constant acceleration (constant rate of change) during the period t1 to t2 (t2(1), t2(2), t2(3)) from when the spool 4 starts to rotate until it reaches the target rotation speed vtg.
However, for example, as shown in Fig. 12A, the spool 4 may be rotationally driven so that the acceleration changes with the passage of time in the period t1 to t2. In the figure, the speed increases in a quadratic curve for each of the spool behaviors GH, GM, and GL.

Also, in order to produce a desired change in the acceleration of the spool during the period t1 to t2, the duty ratio of the motor drive signal during the period t0 to t2 may be changed over time in a predetermined pattern.
As an example, as shown in FIG. 12B, each of the duty ratio transitions DH, DM, and DL may be increased stepwise every time a certain time elapses from time t0.
The number of steps by which the duty ratio is changed during the period t0 to t2 and the elapsed time are not particularly limited and may be changed as appropriate.
The duty ratio may be decreased stepwise during the period t0 to t2.
The amount of increase or decrease in the duty ratio for each step in the period t0 to t2 may be changed as appropriate.
The number of steps by which the duty ratio is changed, the elapsed time, the amount of increase or decrease, etc. may be appropriately varied between the duty ratio transitions DH, DM, and DL.

Also, as shown in FIG. 12(B), the duty ratio may be changed continuously during the period t0 to t2 for each of the duty ratio transitions DH, DM, and DL. In this case, the rate of change of the duty ratio may not be constant but may be changed over time. Note that while the figure shows an example in which the duty ratio changes so as to become continuously larger over the period t0 to t2, the duty ratio may also change so as to decrease continuously from a certain value.

[Second Modification]
In the drive control information of the above embodiment, the drive control parameter serving as a condition determination value used to determine the condition for stopping the rotation of the spool 4 that has begun in response to the operation of the third button 111-3 is the winding length [LENGTH].
However, the drive control parameter serving as the condition determination value may be, for example, the drive time [TIME] other than the winding length [LENGTH]. The drive time [TIME] is the time for which the spool 4 is driven to rotate. Specifically, the drive time [TIME] may be the time from when the operation of the third button 111-3 is detected and the supply of current to the motor 8 that drives the spool 4 is started until the supply of current to the motor 8 is stopped.
In addition, the user may be able to select either the winding length [LENGTH] or the drive time [TIME] as the drive control parameter that is the condition determination value.

[Third 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 for changing the parameter value of the drive control parameter to be changed.
However, the number of operators used for selecting a parameter to be changed or for changing 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 once. Also, 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 positioning of the lever in a predetermined one direction, and the parameter or parameter value to be changed in a reverse order in response to the positioning of the lever in the other direction.

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

[Fifth Modification]
The electric fishing reel 1 may be connected to an external terminal device so as to be able to communicate with it. The communication between the electric fishing reel 1 and the external terminal device may be wireless or wired. The external terminal device may be, for example, a device that displays fish detection information to the user, or may be a smartphone or the like that runs an application that provides predetermined support for fishing using the electric fishing reel 1.
In addition, the drive control information and the intermediate winding speed information corresponding to the automatic jig operation of this embodiment may be stored in an external terminal device. In this case, operations related to changing the drive control parameters and the intermediate winding speed in the drive control information may be made possible as operations on the external terminal device.
When the drive control information and the intermediate winding speed information are stored in the external terminal device in this manner, in order to execute an automatic jigging operation or drive control of the spool 4 at the intermediate winding speed, the drive control information and the intermediate winding speed information are set in the electric fishing reel 1 under the control of the external terminal device. The electric fishing reel 1 performs an automatic jigging operation by controlling the drive of the spool 4 based on the set drive control information and the intermediate winding speed information.

In addition, a program for realizing 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 read into a computer system and executed to perform the processing of the electric fishing reel 1 described above. Here, "reading a program recorded on a recording medium into a computer system and executing it" includes installing the program into a computer system. The "computer system" here includes hardware such as an OS and peripheral devices. In addition, the "computer system" may include multiple computer devices connected via a network including the Internet, WAN, LAN, dedicated lines, and other communication lines. In addition, the "computer-readable recording medium" refers to portable media such as flexible disks, optical magnetic disks, ROMs, and CD-ROMs, and storage devices such as hard disks built into a computer system. In this way, the recording medium storing the program may be a non-transient recording medium such as a CD-ROM. In addition, the recording medium also includes a recording medium provided inside or outside the computer that can be accessed from a distribution server to distribute the program. The code of the program stored in the recording medium of the distribution server may be different from the code of the program in a format executable by a terminal device. In other words, the format in which the program is stored on the distribution server does not matter as long as the program can be downloaded from the distribution server and installed in a form that can be executed on the terminal device. The program may be divided into multiple parts, each of which may be downloaded at a different time 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" includes a storage medium that holds a program for a certain period of time, such as a volatile memory (RAM) inside a computer system that becomes a server or client when a program is transmitted over a network. The program may also be a program that realizes part of the above-mentioned functions. Furthermore, the program may be a so-called difference file (difference program) that can realize the above-mentioned functions in combination with a program already stored in the computer system.
