[0002] Regarding electric cable reels, a type of electric cable reel that uses a pressure sensor in the operating section for changing the winding speed of the spool is known.

[0005] Patent Document 1: Japanese Patent Application Publication No. 10-337138

[0006] Patent Document 2: Japanese Patent Application Publication No. 2021-016316 Summary of the Invention

[0007] The problem that the invention aims to solve

[0008] In the electric reel of Patent Document 1, especially when adjusting the motor speed in conjunction with the fish's pulling force, there is a concern that depending on the angler's grip on the reel or the position of their fingers, excessive pressing force may be applied, causing the motor speed to increase beyond the angler's desired speed. To prevent this, the electric reel of Patent Document 2 is designed with an intermediate output, where a single press only raises the motor output to the intermediate level. However, in this case, there is a concern that the output may unexpectedly increase to the maximum output within the range above the intermediate output when engaging with the fish (resisting the pull).

[0009] The objective of this invention is to prevent the motor output from increasing beyond the angler's expected output in the motor control device of an electric reel.

[0010] Technical solutions for solving the problem

[0011] According to one aspect of the present invention, a motor control device for an electric cable reel drives a spool rotatably mounted on the cable reel body using a motor. The motor control device includes a first pressing part and a motor control part. The first pressing part is disposed on the cable reel body for pressing operations. The motor control part controls the motor output based on the pressing operation of the first pressing part. The motor control part increases the motor output based on at least one of a first pressing force and a pressing time of the first pressing part. When the pressing operation of the first pressing part causes the motor output to change from a state less than a first intermediate output to a state exceeding the first intermediate output, the motor control part limits the motor output to the first intermediate output until the pressing operation of the first pressing part stops. When the pressing operation of the first pressing part causes the motor output to change from a state greater than the first intermediate output but less than a second intermediate output between the first intermediate output and the maximum output to a state exceeding the second intermediate output, the motor control part limits the motor output to the second intermediate output until the pressing operation of the first pressing part stops.

[0012] In the motor control device of this electric reel, if the motor output is lower than the first intermediate output, even if the first pressing part is pressed, the motor output will not increase above the first intermediate output. Therefore, when the motor output is lower than the first intermediate output, even if the first pressing part is pressed with a pressing force greater than expected, the motor output will be limited to not exceeding the first intermediate output. This prevents the motor output from increasing above the angler's expected output.

[0013] Furthermore, if the motor output is above the first intermediate output but below the second intermediate output, pressing the first pressing part will not increase the motor output above the second intermediate output. Therefore, when the pulling force of the fish causes the motor output to vary within the range above the first intermediate output but below the second intermediate output, for example, even if the first pressing part is pressed with a pressing force greater than expected, the motor output will be limited to not exceeding the second intermediate output. That is, it is possible to prevent the motor output from reaching near its maximum output. Thus, when the pulling force of the fish causes the motor output to change, it is possible to prevent the fishing line from breaking and to prevent the electric reel from being subjected to a large load, which could cause the circuit breaker to operate.

[0014] The motor control unit can also maintain the motor output at the first intermediate output when the pressing operation of the first pressing part is stopped while the motor output is limited to the first intermediate output. Alternatively, when the pressing operation of the first pressing part is stopped and the motor output is maintained at the first intermediate output, the motor control unit can increase the motor output relative to the first intermediate output when the first pressing part is pressed again. In this case, since the motor output increases relative to the first intermediate output by re-performing the pressing operation, it is possible to effectively prevent the motor output from increasing beyond the angler's expected output.

[0015] The motor control unit can also maintain the motor output at the second intermediate output when the pressing operation of the first pressing part is stopped while the motor output is limited to the second intermediate output. Alternatively, when the pressing operation of the first pressing part is stopped and the motor output is maintained at the second intermediate output, the motor control unit can increase the motor output relative to the second intermediate output when the first pressing part is pressed again. In this case, since the motor output increases relative to the second intermediate output by re-performing the pressing operation, it is possible to effectively prevent the motor output from increasing beyond the angler's expected output.

[0016] The motor control unit can also perform the following increase / decrease control: In this increase / decrease control, when the pressing operation of the first pressing part is stopped while maintaining the motor output at the second intermediate output, the motor output is increased relative to the second intermediate output based on the first pressing force; when the pressing operation of the first pressing part is stopped while the motor output exceeds the second intermediate output, the motor output is decreased back to the second intermediate output. In this case, the motor output can be adjusted using intuitive operation.

[0017] The motor control unit can also increase the motor output based on an increase in the first pressing pressure, and decrease the motor output to a second intermediate output based on a decrease in the first pressing pressure. In this case, the motor output can be adjusted using more intuitive operation.

[0018] The motor control device may also include a notification unit that notifies the motor control unit of any increase or decrease control being performed. In this case, it is easy to identify that an increase or decrease control is being performed.

[0019] The motor control unit can also maintain the motor output at the time the pressing operation on the first pressing part stops when the motor output is below the second intermediate output. In this case, adjusting the motor output becomes easier.

[0020] The motor control unit may also include a second pressing section on the main body of the reel for pressing operations. The motor control unit can also reduce the motor output based on the second pressing force and the pressing time of the second pressing section, maintaining the motor output when the pressing operation on the second pressing section stops. In this case, adjusting the motor output becomes easier.

[0021] The motor control device may also include a first operating unit provided in the main body of the reel. The motor control unit can also perform graded control of the motor output from a stopped state to maximum output. The motor control unit can also, based on the operation of the first operating unit, set the first output stage corresponding to the first intermediate output and the second output stage corresponding to the second intermediate output to arbitrary output stages. The motor control unit can also interchange the first and second output stages if the first output stage is set to an output stage larger than the second output stage, or if the second output stage is set to an output stage smaller than the first output stage. In this case, it is possible to prevent the first output stage from being set to an output stage larger than the second output stage.

[0022] The motor control device may also include a second operating unit provided in the main body of the reel. The motor control unit can also perform graded control of the motor output from a stopped state to the maximum output. When the motor is being driven at an output lower than the first intermediate output, the motor control device can also change a pre-set first output level corresponding to the first intermediate output based on the operation of the second operating unit. Similarly, when the motor is being driven at an output higher than the first intermediate output but lower than the second intermediate output, the motor control device can change a pre-set second output level corresponding to the second intermediate output based on the operation of the second operating unit. In this case, the setting value of the first output level or the setting value of the second output level can be easily changed while the motor is being driven.

[0023] The motor control unit can also stop the motor output when the fishing line released from the spool reaches the stop line length, and reset the first and second output stages, which have been changed by the operation of the second operation unit, to the preset first and second output stages. In this case, operability is improved.

[0024] In another aspect of the invention, the recording medium stores a program executed by a motor control device of an electric reel, which drives a reel spool rotatably mounted on a reel body having a pressing part for pressing operations using a motor. The program performs the following processing: increasing the motor output based on at least one of the pressing force and the pressing time of the pressing operation on the pressing part; limiting the motor output to the first intermediate output when the pressing operation on the pressing part changes the motor output from a state less than a first intermediate output to a state exceeding the first intermediate output, until the pressing operation on the pressing part stops; and limiting the motor output to the second intermediate output when the pressing operation on the pressing part changes the motor output from a state greater than the first intermediate output and less than a second intermediate output between the first intermediate output and the maximum output, until the pressing operation on the pressing part stops.

[0035] <First Implementation>

[0036] like Figure 1As shown, the electric cable reel 100 obtained by adopting one embodiment of the present invention is an electric cable reel driven by a motor using power supplied by an external power source.

[0037] The electric cable reel 100 includes a cable reel body 1, a cable reel 2, a motor 3, a handle 4, a counter housing 5, a first pressing part 11, a second pressing part 12, and a motor control part 17. The first pressing part 11, the second pressing part 12, and the motor control part 17 constitute part of a motor control device.

[0038] The cable reel body 1 has a housing 6, a first side cover 7 covering one side of the housing 6, a second side cover 8 covering the other side of the housing 6, and a front cover (not shown) covering the front of the housing 6. Inside the cable reel body 1, there is a (not shown) flat winding mechanism that operates in conjunction with the cable reel 2, or a (not shown) rotation transmission mechanism that transmits the rotation of the motor 3 and the handle 4 to the cable reel 2.

[0039] The cable reel 2 is disposed inside the cable reel body 1. The cable reel 2 is rotatably mounted on the cable reel body 1 between the first side cover 7 and the second side cover 8.

[0040] Motor 3 is located inside the winding reel body 1. Motor 3 is controlled by PWM (Pulse Width Modulation) of motor control unit 17, and drives the winding drum 2 to rotate in the winding direction according to the pressing operation of the first pressing unit 11 and the second pressing unit 12.

[0041] The handle 4 is supported on the first side cover 7 and rotates freely.

[0042] The counter housing 5 is disposed on the upper part of the cable reel body 1. The counter housing 5 is fixed to the outer casing 6. The counter housing 5 is provided with a display unit 10 with an LCD display, a first pressing unit 11, a second pressing unit 12, and first to third operation units 13 to 15. The first to third operation units 13 to 15 are mainly used for making various settings on the electric cable reel 100. The first to third operation units 13 to 15 are for pressing operations. The first to third operation units 13 to 15 can also be a touch panel provided on the display unit 10. The counter housing 5 houses a control unit 16 for performing various controls (see reference). Figure 2 ).

[0043] A first pressing part 11 and a second pressing part 12 are provided on the cable reel body 1 for pressing operations. The first pressing part 11 has a pressure sensor 11a. The pressure sensor 11a outputs a detection value corresponding to the magnitude of the pressing force (hereinafter referred to as the first pressing force) of the pressing operation on the first pressing part 11 to the motor control unit 17 in the form of an electrical signal. The second pressing part 12 has a pressure sensor 12a. The pressure sensor 12a outputs a detection value corresponding to the magnitude of the pressing force (hereinafter referred to as the second pressing force) of the pressing operation on the second pressing part 12 to the motor control unit 17 in the form of an electrical signal.

[0044] like Figure 2 As shown, the control unit 16 has a motor control unit 17 for controlling the motor 3 and a display control unit 18 for controlling the display unit 10 as functional structures. The motor control unit 17 controls the output of the motor 3 (hereinafter referred to as motor output) according to the pressing operation of the first pressing unit 11 or the pressing operation of the second pressing unit 12 via a motor drive circuit 19 that performs PWM driving on the motor 3.

[0045] The control unit 16 is connected to a first pressing unit 11, a second pressing unit 12, and first to third operating units 13 to 15. Additionally, the control unit 16 is connected to a display unit 10, a spool sensor 20 for detecting the rotational speed and direction of rotation of the spool 2, and a storage unit 21. The storage unit 21 is, for example, a non-volatile memory, storing various setting information of the electric reel 100, such as information on the bracket position and the rim stop position.

[0046] The motor control unit 17 performs graded control of the motor output from a stopped state to maximum output. The motor control unit 17 increases the motor output (e.g., the rotational speed of the motor 3) based on at least one of a first pressing force and the pressing time of the first pressing part 11. The motor control unit 17 decreases the motor output (e.g., the rotational speed of the motor 3) based on at least one of a second pressing force and the pressing time of the second pressing part 12. In this embodiment, the motor control unit 17 increases the motor output based on the first pressing force and decreases the motor output based on the second pressing force. The motor control unit 17 maintains the motor output when the pressing operation of the first pressing part 11 stops. The motor control unit 17 maintains the motor output when the pressing operation of the second pressing part 12 stops.

[0047] When the pressing operation of the first pressing unit 11 changes the motor output from a state less than the first intermediate output to a state greater than the first intermediate output, the motor control unit 17 limits the motor output to the first intermediate output until the pressing operation of the first pressing unit 11 stops. The first intermediate output is any output that is greater than the output in the stopped state and less than the maximum output. Alternatively, the motor control unit 17 may also limit the motor output to the first intermediate output until the pressing operation of the first pressing unit 11 stops when the pressing operation of the first pressing unit 11 changes the motor output from a state less than the first intermediate output to a state greater than the first intermediate output.

[0048] When the pressing operation of the first pressing unit 11 changes the motor output from a state where it is above the first intermediate output but below the second intermediate output to a state where it exceeds the second intermediate output, the motor control unit 17 limits the motor output to the second intermediate output until the pressing operation of the first pressing unit 11 stops. The second intermediate output is any output between the first intermediate output and the maximum output. Alternatively, the motor control unit 17 may also limit the motor output to the second intermediate output until the pressing operation of the first pressing unit 11 stops when the pressing operation of the first pressing unit 11 changes the motor output from a state where it is above the first intermediate output but below the second intermediate output to a state where it exceeds the second intermediate output.

[0049] When the motor control unit 17 stops pressing the first pressing part 11 while limiting the motor output to the first intermediate output, it maintains the motor output at the first intermediate output. When the motor control unit 1 presses the first pressing part 11 while stopping the pressing operation and maintaining the motor output at the first intermediate output, it increases the motor output compared to the first intermediate output.

[0050] <Motor Control Processing>

[0051] Next, according to Figures 3-5 The flowchart shown illustrates an example of the 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. Here, the motor output is adjusted in stages from 0 to Nmax (Nmax+1 stages). Stage 0 represents the stopped state of the motor 3, and stage Nmax represents the state where the motor 3 is driven at maximum output. For example, the motor output is adjusted in 31 stages.

[0052] Furthermore, lower and upper limits for the pressing force output from pressure sensors 11a and 12a are set here (e.g., lower limit of 30 grams and upper limit of 2 kilograms). Moreover, based on dividing the range of these lower and upper limits into any number of levels (e.g., thirty-one equal parts), the increment and decrement of the motor output stage corresponding to each level are set. Additionally, it is preferable to pre-set that the greater the pressing force, the greater the increment and decrement of the motor output stage.

[0053] Furthermore, motor 3 is controlled using PWM here, with a maximum output at a duty cycle of 100%. The motor output is, for example, the rotational speed of motor 3. Additionally, when a load is applied causing the rotational speed of the winding drum 2 to decrease, feedback control is performed to maintain a specified rotational speed.

[0054] First, in step S1, it is determined whether the first pressing force P1, which applies pressure to the first pressing part 11, is 30g or more. Specifically, for example, this is determined by detecting the output of the pressure sensor 11a from the first pressing part 11 to determine whether the first pressing part 11 is pressed by a pressure of 30g or more. If only an output indicating that the first pressing force P1 is less than 30g is detected, to avoid erroneous operation, it is considered that the first pressing part 11 has not been pressed and this output is ignored. Furthermore, a resistive diaphragm type pressure sensor is used here, and the circuit is configured such that the output pressure is proportional to the pressing force.

[0055] If it is determined in step S1 that the first pressing force P1 is 30g or more, proceed to step S2. In step S2, read the current motor output stage (hereinafter referred to as stage N).

[0056] In step S3, it is determined whether level N is a first output level NM1 or higher corresponding to the first intermediate output. The first output level NM1 is preferably a level in the range of, for example, level 5 to 15. The first output level NM1 is set to, for example, level 10.

[0057] If in step S3 it is determined that stage N is greater than or equal to the first output stage NM1, proceed to step S4. If in step S3 it is determined that stage N is less than or equal to the first output stage NM1, proceed to step S4. Figure 4 The following is step S31. Details regarding step S31 and beyond will be described below.

[0058] In step S4, it is determined whether level N is a second output level NM2 or higher corresponding to the second intermediate output. The second output level NM2 is preferably a level in the range of, for example, level 15 to 25. The second output level NM2 is set to, for example, level 20.

[0059] If in step S4 it is determined that stage N is greater than or equal to the second output stage NM2, proceed to step S5. If in step S4 it is determined that stage N is less than or equal to the second output stage NM2, proceed to step S5. Figure 5 The steps shown are S41 and beyond. Details regarding steps S41 and beyond will be described below.

[0060] In step S5, it is determined whether the first pressing force P1 is less than 2 kg. If it is determined in step S5 that the first pressing force P1 is greater than 2 kg, proceed to step S13, and then set stage N to stage Nmax. That is, increase the motor output to the maximum output. Then, proceed to the next step S11, and maintain the motor output at stage Nmax.

[0061] Furthermore, when the motor output is maintained at level Nmax, and the first pressing part 11 is pressed by a first pressing force P1 of 2Kg or more, step S13 is entered. However, since the motor output has already been maintained at level Nmax, the result is to continue maintaining the motor output at level Nmax.

[0062] When it is determined in step S5 that the first pressing force P1 is less than 2Kg, step S6 is entered, and the preset increment number M for the output of the pressure sensor 11a is read from the storage unit 21.

[0063] In step S7, it is determined whether the level obtained by adding the level increment M to level N is less than Nmax. If it is less than Nmax, proceed to step S8 and set N+M as level N. That is, increase the motor output to level N+M. Specifically, for example, when the first pressing part 11 is pressed by a first pressing force P1 of 300g to 400g while the motor output is at level 22, add a level increment 2 that is pre-set corresponding to the range of the first pressing force P1 to level 22, and set the resulting level 24 as level N. Then, proceed to step S9.

[0064] If, in step S7, it is determined that the level obtained by adding the level increment M to the current level N is greater than or equal to Nmax, then proceed to step S12. Next, a level that is one level smaller than Nmax is set as level N. That is, as long as the first pressing force P1 on the first pressing part 11 does not exceed 2 kg, level N will not reach level Nmax. Then, proceed to step S9.

[0065] In step S9, for example, after a 0.5-second standby period, proceed to step S10.

[0066] In step S10, it is determined, similar to step S1, whether the first pressing force P1 is 30g or more. That is, it is determined whether the first pressing part 11 is still being pressed by the first pressing force P1 of 30g or more. If the first pressing part 11 is being pressed by the first pressing force P1 of 30g or more, the process returns to step S2. If the first pressing part 11 is not being pressed by the first pressing force P1 of 30g or more, the process proceeds to step S11, and then the motor output is maintained at the level N set in step S8 or step S12.

[0067] When it is determined in step S1 that the first pressing force P1 is less than 30g, proceed to step S14.

[0068] In step S14, based on the output from the pressure sensor 12a, it is determined whether the second pressing force P2, which applies pressure to the second pressing part 12, is 30g or more. If only an output indicating that the second pressing force P2 is less than 30g is detected, to avoid erroneous operation, it is considered that the second pressing part 12 has not been pressed, and this output is ignored.

[0069] If it is determined in step S14 that the second pressing force P2 is 30g or more, proceed to step S15 to determine whether level N is 1 or more, i.e., whether motor 3 is being driven. If level N is 0, the operation of the second pressing part 12 used to reduce the output is meaningless, so motor control processing is not performed. If level N is 1 or more, proceed to step S16.

[0070] In step S16, it is determined whether the second pressing force P2 is less than 2 kg. If the second pressing force P2 is greater than 2 kg, proceed to step S24 and change stage N to 0. That is, stop the drive of motor 3.

[0071] If it is determined in step S16 that the second pressing force P2 is less than 2 kg, proceed to step S17 and read level N. Then, proceed to step S18.

[0072] In step S18, the preset reduction number L for the output of pressure sensor 12a is read from the storage unit 21, and the process proceeds to step S19.

[0073] In step S19, it is determined whether the level obtained by subtracting the level reduction factor L from level N is 1 or higher. If the level obtained by subtracting the level reduction factor L from level N is 1 or higher, proceed to step S20 and set N-L as level N. That is, reduce the motor output to level N-L. Then, proceed to step S21.

[0074] If, in step S19, the level obtained by subtracting the level reduction factor L from level N is less than 1, proceed to step S23 to change level N to 1. Then, proceed to step S21.

[0075] In step S21, for example, after a 0.5-second standby period, the process proceeds to step S22.

[0076] In step S22, it is determined, similarly to step S14, whether the second pressing force P2 is 30g or more. That is, it is determined whether the second pressing part 12 is still being pressed by the second pressing force P2 of 30g or more. If the second pressing part 12 is being pressed by the second pressing force P2 of 30g or more, the process returns to step S16. If the second pressing part 12 is not being pressed by the second pressing force P2 of 30g or more, the process proceeds to step S11, and then the motor output is maintained at the level N set in step S20 or step S23.

[0077] Next, refer to Figure 4 The process of motor control when stage N is determined to be less than the first output stage NM1 in step S3 is explained. When stage N is determined to be less than the first output stage NM1 in step S3, the process proceeds to step S31.

[0078] In step S31, the preset increment number M for the output of pressure sensor 11a is read from the storage unit 21. Then, the process proceeds to step S32.

[0079] In step S32, it is determined whether the level obtained by adding the level increment M to the level N is greater than the first output level NM1. If the level obtained by adding the level increment M to the level N is greater than the first output level NM1, proceed to step S33.

[0080] In step S33, the first output stage NM1 is set as stage N. That is, here, the motor output is limited to the first output stage NM1 such that stage N does not exceed the first output stage NM1. Then, proceed to step S34.

[0081] In step S34, for example, after a 0.5-second standby period, proceed to step S35.

[0082] In step S35, it is determined, similarly to step S10, whether the first pressing part 11 is still being pressed by a first pressing force P1 of 30g or more. If the first pressing part 11 is not being pressed by a first pressing force P1 of 30g or more, then proceed to step S11 and maintain the motor output at the first output stage NM1. If the first pressing part 11 is being pressed by a first pressing force P1 of 30g or more, then return to step S33. That is, even if the first pressing part 11 is still being pressed by a first pressing force P1 of 30g or more, the motor output can be maintained at the first output stage NM1.

[0083] If, in step S32, the result of adding the level increment M to level N is less than or equal to the first output level NM1, proceed to step S36, where the result of adding the level increment M to level N is set as the new level N. Then, proceed to step S9.

[0084] Furthermore, in step S32, it can also be determined whether the level obtained by adding the level increment M to level N is greater than or equal to the first output level NM1. That is, in step S32, if it is determined that the level obtained by adding the level increment M to level N is greater than or equal to the first output level NM1, the process proceeds to step S33; if it is determined that the level obtained by adding the level increment M to level N is less than the first output level NM1, the process proceeds to step S36.

[0085] Next, refer to Figure 5 The process of motor control when it is determined in step S4 that stage N is less than the second output stage NM2 is explained. When it is determined in step S4 that stage N is less than the second output stage NM2, the process proceeds to step S41.

[0086] In step S41, the preset increment number M for the output of pressure sensor 11a is read from the storage unit 21. Then, the process proceeds to step S42.

[0087] In step S42, it is determined whether the level obtained by adding the level increment M to the level N is greater than the second output level NM2. If the level obtained by adding the level increment M to the level N is greater than the second output level NM2, proceed to step S43.

[0088] In step S43, the second output stage NM2 is set to stage N. That is, the motor output is limited to the second output stage NM2 such that stage N does not exceed the second output stage NM2. Then, proceed to step S44.

[0089] In step S44, for example, after a 0.5-second standby period, proceed to step S45.

[0090] In step S45, it is determined, similarly to step S10, whether the first pressing part 11 is still being pressed by a first pressing force P1 of 30g or more. If the first pressing part 11 is not being pressed by a first pressing force P1 of 30g or more, then proceed to step S11, and then maintain the motor output in the second output stage NM2. If the first pressing part 11 is being pressed by a first pressing force P1 of 30g or more, then return to step S43. That is, even if the first pressing part 11 is still being pressed by a first pressing force P1 of 30g or more, the motor output can be maintained in the second output stage NM2.

[0091] If, in step S42, the level obtained by adding the level increment M to level N is lower than or equal to the second output level NM2, proceed to step S46, where the level obtained by adding the level increment M to level N is set as the new level N. Then, proceed to step S9.

[0092] Furthermore, in step S42, it can also be determined whether the level obtained by adding the level increment M to level N is greater than or equal to the second output level NM2. That is, in step S42, if it is determined that the level obtained by adding the level increment M to level N is greater than or equal to the second output level NM2, the process proceeds to step S43; if it is determined that the level obtained by adding the level increment M to level N is less than the second output level NM2, the process proceeds to step S46.

[0093] For reference Figures 3-5 As explained, the motor control unit 17 has Figure 6 The characteristics are schematically represented in the diagram. Figure 6 In the diagram, the horizontal axis represents the first pressing force P1, and the vertical axis represents stage N. The dotted-dashed line C1 indicates the characteristic of limiting the motor output to the first output stage NM1. The dotted-dashed line C2 indicates the characteristic of limiting the motor output to the second output stage NM2.

[0094] The motor control unit 17 can set the first output stage NM1 and the second output stage NM2 to any output stage based on the operation of the first operation unit 13. The method for setting the first output stage NM1 is to switch to the mode for setting the first output stage NM1 by operating the first operation unit 13 when the motor output is in a stopped state. At this time, the display control unit 18 causes the display unit 10 to display the mode for setting the first output stage NM1. Then, for example, by pressing the second operation unit 14 or the third operation unit 15, any stage is selected as the first output stage NM1, and the first operation unit 13 is operated again to set the first output stage NM1 to the selected stage. The method for setting the second output stage NM2 is to perform the same setting as for the first output stage NM1 after switching to the mode for setting the second output stage NM2 by operating the first operation unit 13.

[0095] When the first output stage NM1 is set to an output stage greater than the second output stage NM2, or when the second output stage NM2 is set to an output stage less than the first output stage NM1, the motor control unit 17 interchanges the first output stage NM1 and the second output stage NM2. For example, when the first output stage NM1 is set to stage 10 and the second output stage NM2 is set to stage 20, if the first output stage NM1 is set from stage 10 to stage 25, the second output stage NM2 is identified as stage 25, and stage 20 is identified as the first output stage NM1. That is, the motor control unit 17 controls the setting values ​​of the first output stage NM1 and the second output stage NM2 in such a way that the first output stage NM1 is always less than the second output stage NM2.

[0096] When the motor 3 is driven with an output less than the first intermediate output, the motor control unit 17 changes the preset first output level NM1 according to the operation of the first operation unit 13 or the second operation unit 14. When the motor 3 is driven with an output greater than or equal to the first intermediate output but less than the second intermediate output, the motor control unit 17 changes the preset second output level NM2 according to the operation of the first operation unit 13 or the second operation unit 14.

[0097] In detail, when the motor 3 is driven at an output level less than the first output level NM1, the motor control unit 17 decreases the first output level NM1 by one level whenever the first operation unit 13 is operated, and increases the first output level NM1 by one level whenever the second operation unit 14 is operated. When the motor 3 is driven at an output level greater than or equal to the first output level NM1 but less than the second output level NM2, the motor control unit 17 decreases the second output level NM2 by one level whenever the first operation unit 13 is operated, and increases the second output level NM2 by one level whenever the second operation unit 14 is operated. Alternatively, the motor control unit 17 can also perform the following control: increase the first output level NM1 by one level whenever the first operation unit 13 is operated, and decrease the first output level NM1 by one level whenever the second operation unit 14 is operated. The same applies to the second output level NM2.

[0098] When the fishing line released from the spool 2 reaches the stop line length, the motor control unit 17 stops the motor output and resets the first output stage NM1 and the second output stage NM2, which have been changed by the operation of the first operation unit 13 or the second operation unit 14, to their preset values. The stop line length is the length at which the motor output stops, for example, set to a position that facilitates gripping the hook assembly mounted on the fishing line. For example, the motor control unit 17 sets the line length when the third operation unit 15 is pressed and held as the stop line length.

[0099] In this electric reel 100, if the motor output level N is less than the first output level NM1, even if the first pressing part 11 is pressed, the motor output level N will not increase above the first output level NM1. Therefore, when the motor output is less than the first output level NM1, even if the first pressing part 11 is pressed with a first pressing force greater than expected, the motor output will be limited to not exceeding the first output level NM1. This prevents the motor output from increasing above the angler's expected output.

[0100] Furthermore, if the motor output level N is above the first output level NM1 and below the second output level NM2, even if the first pressing part 11 is pressed, the motor output will not increase above the second output level NM2. Therefore, when the motor output varies within the range of above the first output level NM1 and below the second output level NM2 due to the pull of the fish, for example, even if the first pressing part 11 is pressed with a first pressing force greater than expected, the motor output will be limited to not exceeding the second output level NM2. That is, it is possible to prevent the motor output from reaching near its maximum output. Thus, when the motor output changes due to the pull of the fish, it is possible to prevent the fishing line from breaking and to prevent the circuit breaker from operating due to a large load on the electric reel 100.

[0101] <Other Implementation Methods>

[0102] The above describes one embodiment of the present invention, but the present invention is not limited to the described embodiment and various modifications can be made without departing from the spirit of the invention.

[0103] Figure 7 Characteristic C3 represents the increase / decrease control mode of the motor control processing in the modified example. In the modified example, the motor control unit 17 performs motor control processing in the range from the second output stage NM2 to stage Nmax, which differs from the embodiment described above. Otherwise, it is the same as the embodiment described above.

[0104] like Figure 7 As shown, the increase / decrease control mode means that when the output stage of motor 3 is maintained at the second intermediate output (here, the second output stage NM2), and the first pressing part 11 is pressed, the motor output is increased relative to the second intermediate output according to the first pressing force P1. When the pressing operation of the first pressing part 11 is stopped when the motor output exceeds the second intermediate output, the motor output is reduced to the second intermediate output.

[0105] In the increase / decrease control mode, the motor control unit 17 increases the motor output according to the increase of the first pressing force P1, and decreases the motor output to the second intermediate output according to the decrease of the first pressing force P1.

[0106] In the increase / decrease control mode, only during the period when the first pressing part 11 is pressed, the output level of the motor 3 is increased relative to the second output level NM2 according to the first pressing force P1. When the first pressing part 11 is not pressed, the motor output is reduced to the second intermediate output, and the output level of the motor 3 is maintained at the second output level NM2.

[0107] When the motor control unit 17 deactivates the increase / decrease control mode by pressing the second pressing unit 12 to reduce the output stage of the motor 3 relative to the second output stage NM2, the increase / decrease control mode is activated.

[0108] like Figure 8 As shown, the display control unit 18 causes the display unit 10 (an example of a notification unit) to display the state where the motor output is controlled in the increase / decrease control mode. When the increase / decrease control mode is executed, the display control unit 18 causes the display unit 10 to display, for example, "Boost". When the increase / decrease control mode is deactivated, the display control unit 18 causes the display unit 10 to stop displaying "Boost". Furthermore, as a notification method for notifying the execution of increase / decrease control, other methods such as light, sound, or vibration may also be used.

[0109] Furthermore, the modified example is a structure that executes the increment / decrease control mode within the range from the second output stage NM2 to stage Nmax. However, for example, the increment / decrease control mode can also be executed within the range from the first output stage NM1 to the second output stage NM2. In this case, the maximum output stage in the increment / decrease control mode reaches the second output stage NM2. That is, an upper limit for the output stage can also be set in the increment / decrease control mode. After reaching the second output stage NM2, the same motor control processing as in the described embodiment is performed. Furthermore, the maximum output stage in the increment / decrease control mode can also be an output stage smaller than stage Nmax and different from the second output stage NM2.

[0110] The first pressing part 11 and the second pressing part 12 can be interchanged. Alternatively, the functions of the first pressing part 11 and the second pressing part 12 can be interchanged depending on the operation of the first to third operating parts 13 to 15.

[0111] In the embodiment described above, the motor output is adjusted using the first pressing part 11 and the second pressing part 12. However, for example, a pressing part that can switch between two modes—an output increase mode that increases the motor output and an output decrease mode that decreases the motor output—can also be provided to adjust the motor output.

[0112] Pressure sensors 11a and 12a may not be a single component like a pressure-sensitive element, but rather output based on the minute displacement produced by a component pressed by a spring with a large spring constant.

[0113] In the described embodiment, the rotational speed of the spool 2 is detected and used as the motor output for feedback control. However, the current supplied to the motor 3 can also be controlled to make the winding torque a predetermined value. Alternatively, the winding diameter of the spool 2 can be calculated to control the tension to a predetermined value.

[0114] Regarding the control method in the above embodiment for rotating the motor 3 based on the electrical signals output from the pressure sensors 11a and 12a, either the control method of controlling at a specified drum speed or the control method of controlling at a specified torque value can be arbitrarily selected.

[0115] In the described embodiment, when the range of the lower and upper limits of the pressing force output from pressure sensors 11a and 12a is divided into arbitrary levels, the range may not be divided equally. Alternatively, the range of pressing forces corresponding to the levels with lower increments and decrements in the output stages of motor 3 may be greater than the range of the higher levels.

[0116] In the described embodiment, a lower limit and an upper limit of the pressing force detected by the pressure sensors 11a and 12a are preset (for example, a lower limit of 30 grams and an upper limit of 2 kilograms). However, it can also be configured so that the angler can arbitrarily set the lower limit or the upper limit, i.e., the threshold of the pressing force. In this case, it can also be configured to switch to a pressing force setting mode when the first pressing part 11 and the second pressing part 12 are operated with a pressing force of more than a predetermined value while the motor 3 is stopped, thus setting the threshold of the pressing force.

[0117] In the embodiment described above, it is determined whether there is an operation on the first pressing part 11, and then it is determined whether there is an operation on the second pressing part 12. However, it is also possible to compare the outputs of the pressure sensor 11a and the pressure sensor 12a, and determine the one with the larger output, i.e. the one with the larger pressing force, as a valid pressing operation.

[0118] Alternatively, motor control processing can be performed by recording the program for implementing the motor control unit 17 in a recording medium that can be read by a computer, for example, by executing the program recorded in the recording medium by a CPU (Central Processing Unit).
