Description

The present invention relates to a motor control device, and in particular to a motor control device and program for an electric reel that uses a motor to drive a spool rotatably attached to the reel body.

Patent Document 1 discloses a motor control device for an electric reel that increases motor output in response to pressing of a pressing operation unit. When increasing motor output, the motor control device of Patent Document 1 temporarily limits motor output to the intermediate output if the motor output is about to exceed the intermediate output. This prevents the motor output from increasing more than the angler expected.

Japanese Patent Application Laid-Open No. 2021-016316

In Patent Document 1, after the motor output is limited to the intermediate output, the motor output is increased or decreased by pressing the first pressing operation unit and the second pressing operation unit. When anglers adjust the motor output in response to the pull of a fish, they often change the motor output at an output above the intermediate output. For this reason, it is preferable to be able to flexibly adjust the motor output in response to the pull of the fish once the motor output is at the intermediate output or higher.

The objective of this invention is to provide a motor control device for an electric reel that can flexibly adjust motor output above medium output.

A motor control device for an electric reel according to one aspect of the present invention uses a motor to drive a spool rotatably attached to the reel body. The motor control device includes a first pressing unit and a motor control unit. The first pressing unit is provided on the reel body so as to be pressed. The motor control unit increases the motor output in accordance with at least one of the first pressing force applied to press the first pressing unit and the pressing time for which the first pressing unit is pressed. The motor control unit performs adjustment control such that, when the first pressing unit is pressed while the motor output is at or above an intermediate output less than the maximum output, the motor output is increased above the intermediate output in accordance with the first pressing force, and when pressure on the first pressing unit is stopped, the motor output is reduced to the intermediate output.

With this motor control device for electric reels, when the motor output is at or above intermediate output, the motor output can be increased or decreased in response to pressure on the first pressing portion, and when pressure on the first pressing portion is stopped, the motor output is maintained at intermediate output, allowing for flexible adjustment of motor output at or above intermediate output. Furthermore, when the motor output is at or above intermediate output, the motor output can be adjusted intuitively.

In the adjustment control, the motor control unit may increase the motor output as the first pressure increases, and decrease the motor output to the second intermediate output as the first pressure decreases. In this case, the motor output can be adjusted with even more intuitive operation.

The motor control device may further include a second pressing portion provided on the reel body to be pressed. The motor control unit may reduce the output of the motor in accordance with the second pressing force applied to the second pressing portion and the duration of time the second pressing portion is pressed. In this case, it is possible to prevent the motor output from increasing more than the angler expected, and it becomes easier to adjust the motor output.

If the pressing operation on the first pressing unit increases the motor output from a state where the motor output is less than the intermediate output to a state where the motor output exceeds the intermediate output, the motor control unit may limit the motor output to the intermediate output until the pressing operation on the first pressing unit is stopped, and if the motor output when the pressing operation on the first pressing unit is stopped is equal to or less than the intermediate output, the motor control unit may maintain the motor output at the time when the pressing operation on the first pressing unit is stopped. This makes it easier to adjust the motor output.

The upper limit of the motor's output during acceleration/deceleration control may be set to be lower than the motor's maximum output. In this case, it is possible to prevent the motor's output from increasing more than the angler anticipates.

The motor control device may further include a notification unit that notifies the user that the motor control unit is performing acceleration/deceleration control. In this case, it is easy to recognize that acceleration/deceleration control is being performed.

The motor control device may further include an operating unit provided on the reel body. The motor control unit may control the motor output in stages from a stopped state to maximum output. If the motor is driven at an output less than the intermediate output, the motor control unit may change the setting value of the output stage corresponding to the intermediate output in response to operation of the operating unit. In this case, the setting value of the output stage corresponding to the intermediate output can be easily changed while the motor is driven.

The motor control unit may stop the motor output when the fishing line unwound from the spool reaches the stop line length, and may reset the setting value of the output stage corresponding to the intermediate output changed by operating the operating unit to a preset setting value. This improves operability.

The motor control device may further include a pressure sensor that detects the first pressure. In the adjustment control, the motor control unit may control the motor output in stages in a range from one stage greater than the stage corresponding to intermediate output to the stage corresponding to maximum output, depending on the first pressure. The first pressure corresponding to each stage from the stage one stage greater than the stage corresponding to intermediate output to the stage corresponding to maximum output may be divided into a range from the lower limit value to the upper limit value of the first pressure detected by the pressure sensor. In this case, the motor output stage can be adjusted quickly and easily.

A program according to another aspect of the present invention causes a motor control device of an electric reel, which uses a motor to drive a spool rotatably attached to a reel body having a pressing portion, to execute processing to increase the motor output above the intermediate output in response to pressing of the pressing portion when the pressing portion is pressed while the motor output is at or above an intermediate output less than the maximum output, and to decrease the motor output to the intermediate output when pressing of the first pressing portion is stopped.

This invention provides a motor control device for an electric reel that can flexibly adjust motor output above medium output.

FIG. 10 is a diagram illustrating the characteristics of a motor control unit according to a modified example.

As shown in Figure 1, the electric reel 100 embodying one embodiment of the present invention is an electric reel that is motor-driven by power supplied from an external power source.

The electric reel 100 comprises a reel body 1, a spool 2, a motor 3, a handle 4, a counter case 5, a first pressing unit 11, a second pressing unit 12, and a motor control unit 17. The first pressing unit 11, the second pressing unit 12, and the motor control unit 17 constitute part of a motor control device.

The reel body 1 has a frame 6, a first side cover 7 that covers one side of the frame 6, a second side cover 8 that covers the other side of the frame 6, and a front cover (not shown) that covers the front of the frame 6. Inside the reel body 1, there are arranged a level wind mechanism (not shown) that operates in conjunction with the spool 2, and a rotation transmission mechanism (not shown) that transmits the rotation of the motor 3 and handle 4 to the spool 2.

The spool 2 is disposed inside the reel body 1. The spool 2 is rotatably attached to the reel body 1 between the first side cover 7 and the second side cover 8.

The motor 3 is located inside the reel body 1. The motor 3 is PWM controlled by the motor control unit 17, and drives the spool 2 to rotate in the line winding direction in response to the pressing operation of the first pressing portion 11 and the second pressing portion 12.

The handle 4 is rotatably supported by the first side cover 7.

The counter case 5 is located on top of the reel body 1. The counter case 5 is fixed to the frame 6. The counter case 5 is provided with a display unit 10 having an LCD display, a first pressing unit 11, a second pressing unit 12, and first to third operating units 13 to 15. The first to third operating units 13 to 15 are primarily used to configure various settings for the electric reel 100. The first to third operating units 13 to 15 are operated by pressing them. The first to third operating units 13 to 15 may also be touch panels provided on the display unit 10. The counter case 5 houses a control unit 16 (see Figure 2) that performs various controls.

The first pressing portion 11 and the second pressing portion 12 are provided on the reel body 1 so as to be pressed. The first pressing portion 11 has a pressure sensor 11a. The pressure sensor 11a detects a value corresponding to the magnitude of the pressing force (hereinafter referred to as the first pressing force) applied to press the first pressing portion 11 and outputs it to the motor control unit 17 as an electrical signal. The second pressing portion 12 has a pressure sensor 12a. The pressure sensor 12a detects a value corresponding to the magnitude of the pressing force (hereinafter referred to as the second pressing force) applied to press the second pressing portion 12 and outputs it to the motor control unit 17 as an electrical signal.

As shown in FIG. 2, the control unit 16 has, as its functional components, a motor control unit 17 that controls the motor 3 and a display control unit 18 that controls the display unit 10. The motor control unit 17 controls the output of the motor 3 (hereinafter referred to as motor output) in response to a pressing operation on the first pressing unit 11 or a pressing operation on the second pressing unit 12 via a motor drive circuit 19 that PWM drives the motor 3.

The control unit 16 is connected to the first pressing unit 11, the second pressing unit 12, and the first to third operating units 13 to 15. The control unit 16 is also connected to the display unit 10, a spool sensor 20 for detecting the rotation speed and direction of the spool 2, and a memory unit 21. The memory unit 21 is, for example, a non-volatile memory, and stores various setting information for the electric reel 100, such as information on the shelf position and information on the boat side stop position.

The motor control unit 17 controls the motor output in stages from a stopped state to maximum output. The motor control unit 17 increases the motor output (e.g., the rotation speed of the motor 3) in response to at least one of the first pressing force and the pressing time for which the first pressing unit 11 is pressed. The motor control unit 17 decreases the motor output (e.g., the rotation speed of the motor 3) in response to at least one of the second pressing force and the pressing time for which the second pressing unit 12 is pressed. In this embodiment, the motor control unit 17 increases the motor output in response to the first pressing force and decreases the motor output in response to the second pressing force.

When the first pressing unit 11 is pressed while the motor output is at or above an intermediate output that is less than the maximum output, the motor control unit 17 increases the motor output above the intermediate output in accordance with the first pressing force, and when the pressing operation on the first pressing unit 11 stops, decreases the motor output to the intermediate output, performing adjustment control. The intermediate output is an arbitrary output that is greater than the output when the motor is stopped and less than the maximum output.

In the adjustment control, the motor control unit 17 increases the motor output in response to an increase in the first pressing force, and decreases the motor output to an intermediate output in response to a decrease in the first pressing force.

If the pressing operation on the first pressing unit 11 is an operation that increases the motor output from a state below the intermediate output to above the intermediate output, the motor control unit 17 limits the motor output to the intermediate output until the pressing operation on the first pressing unit 11 is stopped, and if the motor output when the pressing operation on the first pressing unit 11 is stopped is equal to or less than the intermediate output, the motor control unit 17 maintains the motor output when the pressing operation on the first pressing unit 11 is stopped. Note that if the pressing operation on the first pressing unit 11 is an operation that increases the motor output from a state below the first intermediate output to equal to or greater than the first intermediate output, the motor control unit 17 may limit the motor output to the first intermediate output until the pressing operation on the first pressing unit 11 is stopped.

If the motor output when the pressing operation on the second pressing unit 12 is stopped is equal to or lower than the intermediate output, the motor control unit 17 maintains the motor output when the pressing operation on the second pressing unit 12 is stopped.

Next, an example of the flow of motor control processing performed by the motor control unit 17 of the control unit 16 when the power supply to the electric reel 100 is on will be described with reference to the flowcharts shown in Figures 3 and 4. Here, the motor output is adjusted in multiple stages from 0 to Nmax (Nmax + 1 stages). Stage 0 is the state in which the motor 3 is stopped, and stage Nmax is the state in which the motor 3 is driven at maximum output. The motor output is adjusted in 31 stages, for example.

In addition, lower and upper limits (e.g., lower limit 30 grams, upper limit 2 kilograms) of the pressure output from pressure sensors 11a and 12a are set. The range between the lower and upper limits is then arbitrarily divided into stages (e.g., 31 equal divisions), and the increments and decrements of the motor output stages corresponding to each stage are set. Note that it is preferable to set the increments and decrements of the motor output stages so that the greater the pressure, the greater the increase in the pressure.

Motor 3 is controlled using the PWM method, with a maximum output at a duty ratio of 100%. Motor output is, for example, the rotational speed of motor 3. When the rotational speed of spool 2 drops due to a load, feedback control is performed to maintain the specified rotational speed.

First, in step S1, it is determined whether the first pressure P1 applied to the first pressing portion 11 is 30 g or greater. Specifically, for example, the output from the pressure sensor 11a of the first pressing portion 11 is detected to determine whether the first pressing portion 11 is pressed with a pressure of 30 g or greater. If an output of the first pressing force P1 of less than 30 g is detected, the output is ignored, assuming that the first pressing portion 11 is not being pressed, to avoid erroneous operation. Note that here, for example, a resistive film-type pressure sensor is used, and the circuit is configured so that the output voltage is proportional to the pressing force.

If it is determined in step S1 that the first pressing force P1 is 30 g or greater, the process proceeds to step S2. In step S2, the current motor output stage (hereinafter referred to as stage N) is read.

In step S3, it is determined whether stage N is equal to or greater than intermediate stage NM, which corresponds to intermediate output. Intermediate stage NM is preferably a stage within the range of stages 5 to 15, for example. Intermediate output is set to, for example, approximately half the maximum output. Therefore, in this embodiment, intermediate stage NM is set to, for example, stage 16. It is preferable that the motor output corresponding to intermediate stage NM be set to an output within the range of 30% to 80% of the maximum output. It is preferable that the motor output corresponding to intermediate stage NM be set to an output within the range of 40% to 70% of the maximum output.

In step S4, it is determined whether the first pressing force P1 is less than 2 kg. If it is determined in step S4 that the first pressing force P1 is 2 kg or more, the process proceeds to step S12, where stage N is set as stage Nmax. In other words, the motor output is increased to its maximum output. Then, the process proceeds to the next step S10, where the motor output is maintained at stage Nmax.

If the first pressing portion 11 is pressed with a first pressing force P1 of 2 kg or more while the motor output is maintained at stage Nmax, the process will proceed to step S12. However, since the motor output is already maintained at stage Nmax, the motor output will continue to be maintained at stage Nmax.

If it is determined in step S4 that the first pressure force P1 is less than 2 kg, the process proceeds to step S5, where the preset step increase number M for the output of the pressure sensor 11a is read from the memory unit 21.

In step S6, it is determined whether stage N plus the step increment number M is less than Nmax. If it is less than Nmax, the process proceeds to step S7, where N+M is set as stage N. That is, the motor output is increased to N+M stages. Specifically, for example, if the motor output is at stage 22 and the first pressing unit 11 is pressed with a first pressing force P1 of 300g to 400g, stage N is set to 24, which is the added step increment number of 2 that is preset to correspond to that range of first pressing force P1. Then the process proceeds to step S8.

If it is determined in step S6 that the current stage N plus the stage increment number M is equal to or greater than Nmax, the process proceeds to step S11, where the stage one stage lower than stage Nmax is set as stage N. In other words, stage N will not become stage Nmax unless the first pressing force P1 on the first pressing unit 11 exceeds 2 kg. Then, the process proceeds to step S8.

In step S8, the system waits for, for example, 0.5 seconds before proceeding to step S9.

In step S9, similar to step S1, it is determined whether the first pressing force P1 is 30 g or greater. That is, it is determined whether the first pressing unit 11 is being pressed with a first pressing force P1 of 30 g or greater. If the first pressing unit 11 is being pressed with a first pressing force P1 of 30 g or greater, the process returns to step S2. If the first pressing unit 11 is not being pressed with a first pressing force P1 of 30 g or greater, the process proceeds to step S10, where the motor output is maintained at stage N set in step S7 or step S11.

If it is determined in step S1 that the first pressing force P1 is less than 30 g, proceed to step S13.

In step S13, it is determined whether the second pressure P2 applied to the second pressing portion 12 is 30 g or greater based on the output from the pressure sensor 12a. If the second pressure P2 output is less than 30 g, the output is ignored, assuming that the second pressing portion 12 is not being pressed, to avoid erroneous operation.

If it is determined in step S13 that the second pressing force P2 is 30 g or greater, the process proceeds to step S14, where it is determined whether stage N is 1 or greater, i.e., whether the motor 3 is driven. If stage N is 0, operating the second pressing unit 12 to reduce output is meaningless, and therefore the motor control process is not executed. If stage N is 1 or greater, the process proceeds to step S15.

In step S15, it is determined whether the second pressing force P2 is less than 2 kg. If the second pressing force P2 is 2 kg or more, the process proceeds to step S23, where stage N is changed to 0. In other words, the drive of motor 3 is stopped.

If it is determined in step S15 that the second pressing force P2 is less than 2 kg, the process proceeds to step S16 and reads the stage N. Then, the process proceeds to step S17.

In step S17, the number of stages L that has been preset for the output of the pressure sensor 12a is read from the memory unit 21, and the process proceeds to step S18.

In step S18, it is determined whether the value obtained by subtracting the number of step reductions L from stage N is 1 or greater. If the value obtained by subtracting the number of step reductions L from stage N is 1 or greater, the process proceeds to step S19, where N-L is set as stage N. In other words, the motor output is reduced to stage N-L. Then, the process proceeds to step S20.

If in step S18 the result of subtracting the number of stages L from stage N is less than 1, proceed to step S22 and change stage N to 1. Then proceed to step S20.

In step S20, the system waits for, for example, 0.5 seconds before proceeding to step S21.

In step S21, similar to step S13, it is determined whether the second pressing force P2 is 30 g or greater. That is, it is determined whether the second pressing unit 12 is being pressed with a second pressing force P2 of 30 g or greater. If the second pressing unit 12 is being pressed with a second pressing force P2 of 30 g or greater, the process returns to step S16. If the second pressing unit 12 is not being pressed with a second pressing force P2 of 30 g or greater, the process proceeds to step S10, and the motor output is maintained at stage N set in step S19 or step S22.

Next, referring to Figure 4, the flow of the motor control process when it is determined in step S3 that stage N is less than intermediate stage NM will be explained. If it is determined in step S3 that stage N is less than intermediate stage NM, the process proceeds to step S31.

In step S31, the preset step increase number M for the output of the pressure sensor 11a is read from the memory unit 21. Then, the process proceeds to step S32.

In step S32, it is determined whether the sum of stage N and stage increment M is greater than the intermediate stage NM. If the sum of stage N and stage increment M in step S32 is equal to or less than the intermediate stage NM, the process proceeds to step S36, where the sum of stage N and stage increment M is set as the new stage N. Then, the process proceeds to step S9.

In step S32, it may be determined whether the sum of stage N and stage increment M is equal to or greater than intermediate stage NM. That is, if it is determined in step S32 that the sum of stage N and stage increment M is equal to or greater than intermediate stage NM, the process may proceed to step S33, and if it is determined that the sum of stage N and stage increment M is less than intermediate stage NM, the process may proceed to step S36.

If step S32 finds that the sum of step increase number M and step N is greater than intermediate step NM, proceed to step S33. In step S33, intermediate step NM is set as step N. That is, the motor output is limited to intermediate step NM so that step N does not exceed intermediate step NM. Then, proceed to step S34.

In step S34, the system waits for, for example, 0.5 seconds before proceeding to step S35.

In step S35, similar to step S9, it is determined whether the first pressing unit 11 is being pressed with a first pressing force P1 of 30 g or more. If the first pressing unit 11 is being pressed with a first pressing force P1 of 30 g or more, the process returns to step S33. In other words, even if the first pressing unit 11 is being pressed with a first pressing force P1 of 30 g or more, the motor output is maintained at the intermediate stage NM. If the first pressing unit 11 is not being pressed with a first pressing force P1 of 30 g or more in step S35, the process proceeds to step S37.

In step S37, the motor output is controlled in the adjustment control mode. The adjustment control mode has the characteristics shown by the dotted line C2 in Figure 5. In Figure 5, the horizontal axis represents the first pressure force P1, and the vertical axis represents the stage N. Note that the dotted line C1 represents the characteristics in which the motor output is limited to the intermediate stage NM.

In the increase/decrease control mode, if the first pressing unit 11 is pressed while the output stage of the motor 3 is maintained at the intermediate stage NM, the motor output is increased above the intermediate stage NM in accordance with the first pressing force P1, and if the pressing operation on the first pressing unit 11 is stopped while the motor output exceeds the intermediate stage NM, the motor output is reduced to the intermediate stage NM.

In the adjustment control mode, the output stage of the motor 3 increases as the first pressing force P1 increases, and decreases to the intermediate stage NM as the first pressing force P1 decreases. In the adjustment control mode, the output stage of the motor 3 increases above the intermediate stage NM in response to the first pressing force P1 only while the first pressing unit 11 is being pressed; if the first pressing unit 11 is not being pressed, the output stage of the motor 3 decreases to the intermediate stage NM and is maintained at the intermediate stage NM.

In this embodiment, the first pressing force P1 corresponding to each stage from the stage one stage greater than the intermediate stage NM to the stage corresponding to maximum output is divided into a range from the lower limit value to the upper limit value of the first pressing force P1 detected by the pressure sensor 11a, and the output stage of the motor 3 is controlled according to the first pressing force P1.

The motor control unit 17 cancels the adjustment control mode when the output stage of the motor 3 decreases below the intermediate stage NM in response to the pressing operation of the second pressing unit 12 during the adjustment control mode. Specifically, in step S38, the motor control unit 17 determines whether the first pressing force P1 is 30 g or greater based on the output from the pressure sensor 11a. If it is determined that the first pressing force P1 is 30 g or greater, the reduction control mode is maintained and the output stage of the motor 3 is controlled in the adjustment control mode. If it is determined in step S38 that the first pressing force P1 is less than 30 g, the process proceeds to step S39.

If it is determined in step S39 that the first pressing force P1 is less than 30 g, the process proceeds to step S39.

In step S39, it is determined whether the second pressing force P2 is 30 g or greater. If it is determined that the second pressing force P2 is 30 g or greater, the process proceeds to step S15, where processing is performed to reduce the output level of the motor 3. This cancels the adjustment control mode. If it is determined in step S39 that the second pressing force P2 is less than 30 g, the adjustment control mode is maintained.

As shown in FIG. 6, the display control unit 18 causes the display unit 10 (an example of a notification unit) to display that the motor output is being controlled in the adjustment control mode. While the adjustment control mode is being executed, the display control unit 18 causes the display unit 10 to display, for example, "Boost." When the adjustment control mode is released, the display control unit 18 causes the display unit 10 to stop displaying "Boost." Note that the notification means for notifying that adjustment control is being executed may be other means such as light, sound, or vibration.

The motor control unit 17 can set the intermediate stage NM to any output stage in response to operation of the first operation unit 13. The intermediate stage NM is set by, for example, operating the first operation unit 13 to switch to the intermediate stage NM setting mode when the motor output is stopped. At this time, the display control unit 18 causes the display unit 10 to display the intermediate stage NM setting mode. Then, for example, the second operation unit 14 or the third operation unit 15 is pressed to select the intermediate stage NM to any stage, and the first operation unit 13 is operated again to set the intermediate stage NM to the selected stage.

If the motor 3 is driven at an output less than the intermediate stage NM, the motor control unit 17 changes the preset setting value for the intermediate stage NM in response to operation of the first operating unit 13 or the second operating unit 14.

In detail, when the motor 3 is driven at an output level lower than the intermediate level NM, the motor control unit 17 decreases the intermediate level NM by one level each time the first operating unit 13 is operated, and increases the intermediate level NM by one level each time the second operating unit 14 is operated. The motor control unit 17 may also perform control such that the intermediate level NM is increased by one level each time the first operating unit 13 is operated, and decreased by one level each time the second operating unit 14 is operated.

When the fishing line unwound from the spool 2 reaches the stop line length, the motor control unit 17 stops the motor output and resets the intermediate stage NM setting, which was changed by operating the first operating unit 13 or the second operating unit 14, to a preset intermediate stage NM. The stop line length is the line length at which motor output is stopped, and is set, for example, to a position that makes it easy to grab the tackle attached to the fishing line. For example, the motor control unit 17 sets the stop line length to the line length when the third operating unit 15 is pressed and held.

With this electric reel 100, when the motor output is at or above intermediate stage NM, the motor output can be increased or decreased in response to pressure on the first pressing portion 11. Furthermore, when pressure on the first pressing portion 11 is stopped, the motor output decreases to intermediate stage NM and is maintained at intermediate stage NM, allowing for flexible adjustment of motor output above intermediate stage NM. Furthermore, when the motor output is at or above intermediate stage NM, the motor output can be adjusted intuitively.

<Other Embodiments>
Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the invention.

In the above embodiment, if the pressing operation on the first pressing unit 11 is an operation that causes the motor output to exceed the intermediate output from a state below the intermediate output, the motor control unit 17 limits the motor output to the intermediate output until the pressing operation on the first pressing unit 11 is stopped. However, it is not necessary to limit the motor output to the intermediate output when the pressing operation on the first pressing unit 11 is an operation that causes the motor output to exceed the intermediate output from a state below the intermediate output.

Figure 7 is a diagram illustrating the characteristics of the motor control unit according to the first modified example. If the pressing operation on the first pressing unit 11 is an operation that changes the motor output from a state below the first intermediate output to the intermediate output or higher and from a state below the second intermediate output to the second intermediate output or higher, the motor control unit 17 may limit the motor output to the second intermediate output until the pressing operation on the first pressing unit 11 is stopped. The second intermediate output is any output between the first intermediate output and the maximum output.

That is, the motor control unit 17 may have the characteristics shown by the dashed line C3 in Figure 7. If the pressing operation on the first pressing unit 11 is an operation in which the output stage of the motor 3 exceeds the second intermediate stage NM2 from a state in which the output stage is equal to or greater than the intermediate stage NM and less than the second intermediate stage NM2 corresponding to the second intermediate output, the motor control unit 17 may limit the motor output to the second intermediate stage NM2 until the pressing operation on the first pressing unit 11 is stopped. In this case, the motor control unit 17 controls the motor output in the adjustment control mode in the range from the second intermediate stage NM2 to stage Nmax.

Also, as shown in FIG. 8 , an upper limit for motor output may be set in the adjustment control mode. The upper limit output of the motor 3 in the adjustment control mode is set to be smaller than the maximum output of the motor 3. For example, the adjustment control mode may be executed in the range from the intermediate stage NM to the second intermediate stage NM2. In this case, the upper limit output stage in the adjustment control mode is the second intermediate stage NM2. In the adjustment control mode, after the output stage of the motor 3 reaches the second intermediate stage NM2 in response to the pressing operation of the first pressing unit 11, the output of the motor 3 may be maintained at the second intermediate stage NM2. When the pressing operation of the first pressing unit 11 is stopped and the first pressing unit 11 is pressed again, the output of the motor 3 may be increased above the second intermediate stage NM2. Note that the upper limit for motor output in the adjustment control mode may be an output stage different from the second intermediate stage NM2.

The positions of the first pressing unit 11 and the second pressing unit 12 may be interchangeable. Alternatively, the functions of the first pressing unit 11 and the second pressing unit 12 may be interchangeable depending on the operation of the first to third operating units 13 to 15.

In the above embodiment, the motor output was adjusted using two pressing parts, the first pressing part 11 and the second pressing part 12. However, the motor output may also be adjusted by providing a single pressing part that can switch between two modes, for example, an output increase mode in which the motor output increases, and an output decrease mode in which the motor output decreases.

The pressure sensors 11a and 12a may not be individual components such as pressure-sensitive elements, but may output signals in response to minute displacements of a member pressed by a spring with a large spring constant.

In the above embodiment, the rotational speed of the spool 2 was detected as the motor output and feedback controlled, but the current value supplied to the motor 3 may also be controlled so that the winding torque is a predetermined value. Alternatively, the line diameter wound on the spool 2 may be calculated and the tension may be controlled to a predetermined value.

In the above embodiment, the control method for rotating the motor 3 in response to the electrical signals output from the pressure sensors 11a and 12a may be selectable from two options: control at a predetermined spool rotation speed, or control at a predetermined torque value.

In the above embodiment, when dividing the range between the lower and upper limits of the pressure force output from the pressure sensors 11a and 12a into arbitrary stages, the range does not have to be divided equally. The range of pressure force corresponding to stages with low step increments and decrements in the motor 3 output stage may be larger than the range of high steps.

In the above embodiment, the lower and upper limits of the pressure detected by the pressure sensors 11a and 12a (e.g., a lower limit of 30 grams and an upper limit of 2 kilograms) were set in advance, but the lower and upper limits, i.e., the pressure thresholds, may be set by the angler. In this case, when the motor 3 is stopped and the first pressing unit 11 and the second pressing unit 12 are operated with a pressure equal to or greater than a predetermined value, the device may enter a pressure setting mode in which the pressure threshold is set.

In the above embodiment, the presence or absence of operation of the first pressing portion 11 is determined first, followed by the presence or absence of operation of the second pressing portion 12. However, the outputs of both pressure sensors 11a and 12a may be compared, and the one with the greater output, i.e., the greater pressing force, may be determined to be the valid pressing operation.

The program for realizing the motor control processing of the motor control unit 17 described above may be recorded on a computer-readable recording medium, and the motor control processing may be performed by, for example, a CPU (Central Processing Unit) executing the program recorded on the recording medium.
