Abstract

The present invention relates to a motor control device of an electric reel, which can prevent the motor output from increasing above the output expected by the angler. A motor control device for an electric reel (100) is provided with a first pressing unit (11) and a motor control unit (17). A motor control unit (17) increases the output of the motor (3) in response to the pressing operation of the first pressing unit (11). When the pressing operation of the first pressing unit (11) is an operation for changing the output of the motor (3) from a state smaller than the first intermediate output to an operation exceeding the first intermediate output, the motor control unit (17) limits the output of the motor (3) to the first intermediate output until the pressing operation of the first pressing unit (11) is stopped. When the pressing operation of the first pressing unit (11) is an operation in which the output of the motor (3) is changed from a state in which the output is equal to or higher than the first intermediate output and lower than the second intermediate output between the first intermediate output and the maximum output to an operation in which the output exceeds the second intermediate output, the motor control unit (17) limits the output of the motor (3) to the second intermediate output until the pressing operation of the first pressing unit (11) is stopped.

Problems to be solved by the invention

In the electric reel of patent document 1, particularly, when the rotational speed of the motor is adjusted in conjunction with the pulling force of the fish, a pressing force greater than a predetermined level may be generated depending on the posture of the angler gripping the reel, the position of the finger, or the like, and the rotational speed of the motor may be increased to a speed greater than the predetermined speed of the angler. To prevent this, an intermediate output is set in the electric reel of patent document 2, and only the motor output can be brought to the intermediate output by one press. However, in this case, there is a concern that the maximum output is unexpectedly increased in a range of not less than the intermediate output for pulling (resisting) with the fish.

The subject of the invention is to prevent the motor output from increasing above the output expected by the angler in the motor control device of the electric reel.

Technical scheme for solving problems

The motor control device of the electric reel according to one embodiment of the present invention drives a spool rotatably mounted on a reel body by a motor. The motor control device is provided with a first pressing part and a motor control part. The first pressing portion is provided on the reel body so as to perform a pressing operation. The motor control unit controls the motor output in response to the pressing operation of the first pressing unit. The motor control unit increases the motor output in accordance with at least one of a first pressing force for pressing the first pressing unit and a pressing time for pressing the first pressing unit. When the pressing operation of the first pressing portion is an operation to change the motor output from a state smaller than the first intermediate output to an operation exceeding the first intermediate output, the motor control portion limits the motor output to the first intermediate output until the pressing operation of the first pressing portion is stopped. The motor control unit limits the motor output to the second intermediate output until the pressing operation on the first pressing unit is stopped, when the pressing operation on the first pressing unit is an operation that changes the motor output from a state of the first intermediate output or more to a state of the second intermediate output smaller than a state of the second intermediate output between the first intermediate output and the maximum output to a state exceeding the second intermediate output.

In the motor control device of the electric reel, if the motor output is smaller than the first intermediate output, the motor output is not increased above the first intermediate output even if the first pressing portion is pressed. Therefore, when the motor output is smaller than the first intermediate output, for example, even if the first pressing portion is pressed with a pressing force that is not smaller than the expected pressing force, the motor output is limited not to exceed the first intermediate output. This can prevent the motor output from increasing above the output expected by the angler.

In addition, if the motor output is not less than the first intermediate output and less than the second intermediate output, the motor output is not increased to not less than the second intermediate output even if the first pressing portion is pressed. Therefore, when the motor output is changed in a range of the first intermediate output or more and less than the second intermediate output in combination with the pulling force of the fish, for example, even if the first pressing portion is pressed with a pressing force that is expected or more, the motor output is limited not to exceed the second intermediate output. That is, the motor output can be suppressed from reaching the vicinity of the maximum output. Thus, when the motor output is changed in combination with the pulling force of the fish, the breaking of the fishing line and the application of a large load to the electric reel can be suppressed, and the breaker (breaker) can be operated.

The motor control unit may maintain the motor output at the first intermediate output when the pressing operation of the first pressing unit is stopped in a state where the motor output is limited to the first intermediate output. The motor control unit may increase the motor output as compared with the first intermediate output when the pressing operation is performed on the first pressing unit in a state in which the pressing operation on the first pressing unit is stopped and the motor output is maintained at the first intermediate output. In this case, since the motor output is increased as compared with the first intermediate output by repeating the pressing operation, the motor output can be effectively prevented from increasing above the output expected by the angler.

The motor control unit may maintain the motor output at the second intermediate output when the pressing operation on the first pressing unit is stopped in a state where the motor output is limited to the second intermediate output. The motor control unit may increase the motor output as compared with the second intermediate output when the first pressing unit is pressed while the pressing operation of the first pressing unit is stopped and the motor output is maintained at the second intermediate output. In this case, since the motor output is increased as compared with the second intermediate output by re-performing the pressing operation, it is possible to effectively prevent the motor output from increasing above the output expected by the angler.

The motor control unit may perform the following increase/decrease control: in the increase/decrease control, when the pressing operation on the first pressing portion is stopped while maintaining the motor output at the second intermediate output, the motor output is increased as compared with the second intermediate output according to the first pressing force, and when the pressing operation on the first pressing portion is stopped while the motor output exceeds the second intermediate output, the motor output is reduced to the second intermediate output. In this case, the motor output can be adjusted by an intuitive operation.

In the increase/decrease control, the motor control unit may increase the motor output according to an increase in the first pressing force, and decrease the motor output to the second intermediate output according to a decrease in the first pressing force. In this case, the motor output can be adjusted with a more intuitive operation.

The motor control device may further include a notification unit that notifies the motor control unit of the increase/decrease control. In this case, it can be easily recognized that the increase/decrease control is being performed.

The motor control unit may maintain the motor output at the time of stopping the pressing operation on the first pressing unit when the motor output at the time of stopping the pressing operation on the first pressing unit is equal to or lower than the second intermediate output. In this case, adjustment of the motor output becomes easy.

The motor control device may further include a second pressing portion provided on the reel body so as to perform a pressing operation. The motor control unit may reduce the motor output according to a second pressing force for pressing the second pressing unit and a pressing time for pressing the second pressing unit, and maintain the motor output when the pressing operation on the second pressing unit is stopped. In this case, adjustment of the motor output becomes easy.

The motor control device may further include a first operation unit provided in the reel body. The motor control unit may perform the stepwise control of the motor output from the stopped state to the maximum output. The motor control unit may set the first output stage corresponding to the first intermediate output and the second output stage corresponding to the second intermediate output as arbitrary output stages according to the operation of the first operation unit. The motor control unit may exchange the first output stage and the second output stage with each other when the first output stage is set to an output stage larger than the second output stage or when the second output stage is set to an output stage smaller than the first output stage. In this case, the first output stage can be prevented from being set to an output stage larger than the second output stage.

The motor control device may further include a second operation unit provided in the reel body. The motor control unit may perform the stepwise control of the motor output from the stopped state to the maximum output. The motor control device may change the preset first output stage corresponding to the first intermediate output according to the operation of the second operation unit when the motor is being driven at an output smaller than the first intermediate output. The motor control device may change the preset second output stage corresponding to the second intermediate output according to the operation of the second operation unit when the motor is driven at the output equal to or higher than the first intermediate output and smaller than the second intermediate output. In this case, the set value of the first output stage or the set value of the second output stage can be easily changed when the motor is being driven.

The motor control unit may stop the motor output when the fishing line fed from the spool reaches the stop line length, and reset the first output stage and the second output stage changed by the operation of the second operation unit to the first output stage and the second output stage set in advance. In this case, the operability improves.

A recording medium according to another aspect of the present invention stores a program executed by a motor control device of an electric reel for driving a reel rotatably mounted on a reel body having a pressing portion for performing a pressing operation by a motor, the program being for executing: increasing the motor output according to at least one of a pressing force for pressing the pressing portion and a pressing time for pressing the pressing portion; when the pressing operation to the pressing portion is an operation to change the motor output from a state smaller than the first intermediate output to an operation exceeding the first intermediate output, the motor output is limited to the first intermediate output until the pressing operation to the pressing portion is stopped; and limiting the motor output to the second intermediate output until the pressing operation of the pressing portion is stopped, when the pressing operation of the pressing portion is an operation that changes the motor output from a state of the first intermediate output or more and less than the second intermediate output between the first intermediate output and the maximum output to an operation exceeding the second intermediate output.

Effects of the invention

According to the present invention, in the motor control device of the electric reel, the motor output can be prevented from increasing above the output expected by the angler.

Detailed Description

< first embodiment >, first embodiment

As shown in fig. 1, an electric reel 100 according to an embodiment of the present invention is an electric reel driven by a motor using electric power supplied from an external power source.

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

The 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 reel body 1, a not-shown flat winding mechanism that operates in conjunction with the spool 2, a not-shown rotation transmission mechanism that transmits rotation of the motor 3 and the handle 4 to the spool 2, and the like are disposed.

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

The motor 3 is disposed inside the reel body 1. The motor 3 is controlled by PWM (Pulse Width Modulation ) of the motor control unit 17, and rotationally drives the spool 2 in the spool winding direction in accordance with the pressing operation of the first pressing unit 11 and the second pressing unit 12.

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

The counter housing 5 is disposed at the upper portion of the reel body 1. The counter housing 5 is fixed to the outer casing 6. The counter housing 5 is provided with a display portion 10 having a liquid crystal display, a first pressing portion 11, a second pressing portion 12, and first to third operation portions 13 to 15. The first to third operating units 13 to 15 are mainly used for various settings of the electric reel 100. The first to third operation units 13 to 15 are provided for pressing operations. The first to third operation units 13 to 15 may be touch panels provided in the display unit 10. A control unit 16 (see fig. 2) for performing various controls is housed in the counter housing 5.

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

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

The first pressing portion 11, the second pressing portion 12, and the first to third operating portions 13 to 15 are connected to the control portion 16. The control unit 16 is connected to a display unit 10, a spool sensor 20 for detecting the rotational speed and rotational direction of the spool 2, and a storage unit 21. The storage unit 21 is, for example, a nonvolatile memory, and stores various setting information of the electric reel 100, such as information on the holder position and information on the rim stop position.

The motor control unit 17 performs a stepwise control of the motor output from the stopped state to the maximum output. The motor control unit 17 increases the motor output (for example, the rotation speed of the motor 3) in accordance with at least one of the first pressing force and the pressing time for the pressing operation of the first pressing unit 11. The motor control unit 17 decreases the motor output (for example, the rotation speed of the motor 3) according to at least one of the second pressing force and the pressing time for the pressing operation of the second pressing unit 12. The motor control unit 17 of the present embodiment increases the motor output according to the first pressing force and decreases the motor output according to the second pressing force. The motor control unit 17 maintains the motor output when the pressing operation on the first pressing unit 11 is stopped. The motor control unit 17 maintains the motor output when the pressing operation on the second pressing unit 12 is stopped.

When the pressing operation to the first pressing portion 11 is an operation to change the motor output from a state smaller than the first intermediate output to an operation exceeding the first intermediate output, the motor control portion 17 limits the motor output to the first intermediate output until the pressing operation to the first pressing portion 11 is stopped. The first intermediate output is any output that is greater than the output in the stopped state and less than the maximum output. Further, 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, when the pressing operation on the first pressing unit 11 is an operation to change the motor output from a state smaller than the first intermediate output to the first intermediate output or more.

When the pressing operation of the first pressing portion 11 is an operation to change the motor output from the state of the first intermediate output or more and less than the second intermediate output to the state of exceeding the second intermediate output, the motor control portion 17 limits the motor output to the second intermediate output until the pressing operation of the first pressing portion 11 is stopped. The second intermediate output is any output between the first intermediate output and the maximum output. Further, 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, when the pressing operation on the first pressing unit 11 is an operation to change the motor output from the state of the first intermediate output or higher to the state of the second intermediate output or higher.

The motor control unit 17 maintains the motor output at the first intermediate output when the pressing operation on the first pressing unit 11 is stopped in a state where the motor output is limited to the first intermediate output. The motor control unit 1 increases the motor output compared to the first intermediate output when the pressing operation is performed on the first pressing unit 11 in a state in which the pressing operation on the first pressing unit 11 is stopped and the motor output is maintained at the first intermediate output.

Motor control processing

Next, an example of the flow of the motor control process performed by the motor control unit 17 of the control unit 16 when the power supply of the electric reel 100 is in the on state will be described with reference to flowcharts shown in fig. 3 to 5. Here, the motor output is adjusted stepwise from 0 to Nmax in a plurality of stages (nmax+1 stages). The 0-stage is a stopped state of the motor 3, and the Nmax-stage is a state in which the motor 3 is driven at the maximum output. The motor output is adjusted, for example, in 31 steps.

Here, a lower limit value and an upper limit value (for example, a lower limit value of 30 g and an upper limit value of 2 kg) of the pressing force output from the pressure sensors 11a and 12a are set. Then, the range of the lower limit value and the upper limit value is divided into any number of stages (for example, thirty-one parts), and the number of increases and decreases of the motor output stages corresponding to the respective stages are set. It is preferable that the number of increases and decreases in the motor output stage is set to be larger as the pressing force is larger.

Here, the motor 3 is controlled by PWM, and the maximum output is 100% of the duty ratio. The motor output is, for example, the rotational speed of the motor 3. When a load is applied to reduce the rotational speed of the spool 2, feedback control is performed so as to maintain a predetermined rotational speed.

First, in step S1, it is determined whether or not the first pressing force P1 for pressing the first pressing portion 11 is 30g or more. Specifically, for example, by detecting the output from the pressure sensor 11a of the first pressing portion 11, it is determined whether or not the first pressing portion 11 is pressed by a pressing force of 30g or more. When only the output of the degree of less than 30g of the first pressing force P1 is detected, it is considered that the first pressing portion 11 is not pressed in order to avoid the erroneous operation, and the output is ignored. Here, for example, a resistive film type pressure sensor is used, and a circuit is configured such that the pressure as an output is proportional to the pressing force.

When it is determined in step S1 that the first pressing force P1 is 30g or more, the flow advances 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 or not the stage N is the first output stage NM1 or more corresponding to the first intermediate output. The first output stage NM1 is preferably a stage in the range of stages 5 to 15, for example. The first output stage NM1 is set to, for example, stage 10.

When it is determined in step S3 that the stage N is equal to or higher than the first output stage NM1, the routine proceeds to step S4. When it is determined in step S3 that the stage N is smaller than the first output stage NM1, the process advances to step S31 shown in fig. 4. Details about step S31 and later will be described below.

In step S4, it is determined whether or not the stage N is the second output stage NM2 or more corresponding to the second intermediate output. The second output stage NM2 is preferably a stage in the range of stages 15 to 25, for example. The second output stage NM2 is set to, for example, stage 20.

When it is determined in step S4 that the stage N is equal to or higher than the second output stage NM2, the routine proceeds to step S5. When it is determined in step S4 that the stage N is smaller than the second output stage NM2, the process advances to step S41 shown in fig. 5. Details about step S41 and later will be described below.

In step S5, it is determined whether the first pressing force P1 is less than 2Kg. When it is determined in step S5 that the first pressing force P1 is 2Kg or more, the flow proceeds to step S13, and then the stage N is set to the stage Nmax. I.e. to increase the motor output to maximum output. Then, the process advances to the next step S11 to maintain the motor output at the stage Nmax.

Further, when the first pressing portion 11 is pressed by the first pressing force P1 of 2Kg or more in a state where the motor output is maintained at the stage Nmax, the process advances to step S13, but since the motor output has already been maintained at the stage Nmax, the motor output is continued to be maintained at the stage Nmax as a result.

When it is determined in step S5 that the first pressing force P1 is smaller than 2Kg, the routine proceeds to step S6, where the step increase number M preset for the output of the pressure sensor 11a is read out from the storage unit 21.

In step S7, it is determined whether the stage obtained by adding the stage N to the stage increment M is smaller than Nmax. When less than Nmax, the process advances to step S8, where n+m is set to stage N. I.e. the motor output is increased to N + M stages. Specifically, for example, when the first pressing portion 11 is pressed by the first pressing force P1 of 300g to 400g in a state where the motor output is the stage 22, the stage 22 is added with the stage increment number 2 set in advance in correspondence with the range of the first pressing force P1, and the resulting stage 24 is set as the stage N. Then, the process advances to step S9.

When it is determined in step S7 that the current stage N plus the stage increment M is equal to or greater than Nmax, the flow proceeds to step S12, and then a stage 1 smaller than Nmax is set as stage N. That is, as long as the first pressing force P1 to the first pressing portion 11 does not exceed 2Kg, the stage N does not reach the stage Nmax. Then, the process advances to step S9.

In step S9, for example, the process advances to step S10 after waiting for 0.5 seconds.

In step S10, it is determined whether or not the first pressing force P1 is 30g or more as in step S1. That is, it is determined whether or not the first pressing portion 11 is still pressed by the first pressing force P1 of 30g or more. If the first pressing portion 11 is pressed by the first pressing force P1 of 30g or more, the process returns to step S2. If the first pressing portion 11 is not pressed by the first pressing force P1 of 30g or more, the process advances to step S11, and then the motor output is maintained at the stage N set in step S8 or step S12.

When it is determined in step S1 that the first pressing force P1 is smaller than 30g, the routine proceeds to step S14.

In step S14, it is determined whether or not the second pressing force P2 for pressing the second pressing portion 12 is 30g or more, based on the output from the pressure sensor 12 a. When only the output of the degree of less than 30g of the second pressing force P2 is detected, it is considered that the second pressing portion 12 is not pressed in order to avoid the erroneous operation, and the output is ignored.

When it is determined in step S14 that the second pressing force P2 is 30g or more, the routine proceeds to step S15, where it is determined whether or not the stage N is 1 or more, that is, whether or not the motor 3 is being driven. If the stage N is 0, the operation of the second pressing portion 12 for reducing the output is meaningless, so the motor control process is not performed. If the stage N is 1 or more, the process advances to step S16.

In step S16, it is determined whether the second pressing force P2 is less than 2Kg. When the second pressing force P2 is 2Kg or more, the process proceeds to step S24, where the stage N is changed to 0. That is, the driving of the motor 3 is stopped.

When it is determined in step S16 that the second pressing force P2 is smaller than 2Kg, the flow proceeds to step S17, where the stage N is read. Then, the process advances to step S18.

In step S18, the step reduction number L preset for the output of the pressure sensor 12a is read out from the storage unit 21, and the flow advances to step S19.

In step S19, it is determined whether or not the stage obtained by subtracting the stage reduction number L from the stage N is 1 or more. When the stage obtained by subtracting the stage reduction number L from the stage N is 1 or more, the process advances to step S20, where N-L is set as the stage N. I.e. the motor output is reduced to the N-L stage. Then, the process advances to step S21.

When the stage N minus the stage reduction number L is smaller than 1 in step S19, the routine proceeds to step S23, where the stage N is changed to 1. Then, the process advances to step S21.

In step S21, for example, the process advances to step S22 after waiting for 0.5 seconds.

In step S22, it is determined whether or not the second pressing force P2 is 30g or more as in step S14. That is, it is determined whether or not the second pressing portion 12 is still pressed by the second pressing force P2 of 30g or more. If the second pressing portion 12 is pressed by the second pressing force P2 of 30g or more, the process returns to step S16. If the second pressing portion 12 is not pressed by the second pressing force P2 of 30g or more, the process advances to step S11, and then the motor output is maintained at the stage N set in step S20 or step S23.

Next, with reference to fig. 4, a flow of the motor control process when it is determined in step S3 that the stage N is smaller than the first output stage NM1 will be described. When it is determined in step S3 that the stage N is smaller than the first output stage NM1, the flow advances to step S31.

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

In step S32, it is determined whether the stage N plus the stage increment number M is larger than the first output stage NM1. When the stage N plus the stage increment number M is larger than the first output stage NM1, the process advances to step S33.

In step S33, the first output stage NM1 is set to stage N. That is, here, the motor output is limited to the first output stage NM1 in such a manner that the stage N does not exceed the first output stage NM1. Then, the process advances to step S34.

In step S34, for example, the process advances to step S35 after waiting for 0.5 seconds.

In step S35, it is determined whether or not the first pressing portion 11 is still pressed by the first pressing force P1 of 30g or more, as in step S10. If the first pressing portion 11 is not pressed by the first pressing force P1 of 30g or more, the process advances to step S11, where the motor output is maintained at the first output stage NM1. If the first pressing portion 11 is pressed by the first pressing force P1 of 30g or more, the process returns to step S33. That is, even if the first pressing portion 11 is still pressed by the first pressing force P1 of 30g or more, the motor output can be maintained at the first output stage NM1.

When the result of adding the stage N to the stage increment M is equal to or smaller than the first output stage NM1 in step S32, the flow proceeds to step S36, where the result of adding the stage N to the stage increment M is set as a new stage N. Then, the process advances to step S9.

In step S32, it may be determined whether or not the stage obtained by adding the stage N to the stage increment M is equal to or greater than the first output stage NM 1. That is, in step S32, when it is determined that the stage obtained by adding the stage N to the stage increment M is equal to or greater than the first output stage NM1, the flow may proceed to step S33, and when it is determined that the stage obtained by adding the stage N to the stage increment M is smaller than the first output stage NM1, the flow may proceed to step S36.

Next, a flow of the motor control process when it is determined in step S4 that the stage N is smaller than the second output stage NM2 will be described with reference to fig. 5. When it is determined in step S4 that the stage N is smaller than the second output stage NM2, the flow advances to step S41.

In step S41, the step increase number M preset for the output of the pressure sensor 11a is read out from the storage unit 21. Then, the process advances to step S42.

In step S42, it is determined whether the stage N plus the stage increment number M is larger than the second output stage NM2. When the stage N plus the stage increment number M is larger than the second output stage NM2, the process proceeds to step S43.

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 here in such a way that the stage N does not exceed the second output stage NM2. Then, the process advances to step S44.

In step S44, for example, the process advances to step S45 after waiting for 0.5 seconds.

In step S45, it is determined whether or not the first pressing portion 11 is still pressed by the first pressing force P1 of 30g or more, as in step S10. If the first pressing portion 11 is not pressed by the first pressing force P1 of 30g or more, the process advances to step S11, and then the motor output is maintained at the second output stage NM2. If the first pressing portion 11 is pressed by the first pressing force P1 of 30g or more, the process returns to step S43. That is, even if the first pressing portion 11 is still pressed by the first pressing force P1 of 30g or more, the motor output can be maintained at the second output stage NM2.

When the stage obtained by adding the stage N to the stage increment M is equal to or smaller than the second output stage NM2 in step S42, the flow proceeds to step S46, where the stage obtained by adding the stage N to the stage increment M is set as a new stage N. Then, the process advances to step S9.

In step S42, it may be determined whether or not the stage obtained by adding the stage N to the stage increment M is equal to or greater than the second output stage NM2. That is, in step S42, when it is determined that the stage obtained by adding the stage N by the stage increment M is equal to or greater than the second output stage NM2, the flow may proceed to step S43, and when it is determined that the stage obtained by adding the stage N by the stage increment M is smaller than the second output stage NM2, the flow may proceed to step S46.

As described with reference to fig. 3 to 5, the motor control unit 17 has the characteristics schematically shown in fig. 6. In fig. 6, the horizontal axis represents the first pressing force P1, and the vertical axis represents the level N. The dash-dot line C1 indicates a characteristic of restricting the motor output to the first output stage NM 1. The dash-dot line C2 indicates the characteristic of limiting the motor output to the second output stage NM 2.

The motor control unit 17 can set the first output stage NM1 and the second output stage NM2 to arbitrary output stages according to the operation of the first operation unit 13. The setting method of the first output stage NM1 is to switch to a mode for setting the first output stage NM1 by, for example, operating the first operation unit 13 when the motor output is in a stopped state. At this time, the display control section 18 causes the display section 10 to display a mode for setting the first output stage NM 1. Then, for example, by performing a pressing operation on the second operation section 14 or the third operation section 15, an arbitrary stage is selected as the first output stage NM1, and the first operation section 13 is operated again, whereby the first output stage NM1 is set as the selected stage. The setting method of the second output stage NM2 is to perform the same setting as the first output stage NM1 after switching to the mode for setting the second output stage NM2 by operating the first operation unit 13.

The motor control unit 17 exchanges the first output stage NM1 and the second output stage NM2 with each other when the first output stage NM1 is set to an output stage larger than the second output stage NM2 or when the second output stage NM2 is set to an output stage smaller than the first output stage NM1. For example, when the first output stage NM1 is set from the stage 10 to the stage 25 in a state where the first output stage NM1 is set to the stage 10 and the second output stage NM2 is set to the stage 20, the second output stage NM2 is recognized as the stage 25 and the stage 20 is recognized as the first output stage NM1. That is, the motor control unit 17 controls the setting value of the first output stage NM1 and the setting value of the second output stage NM2 so that the first output stage NM1 becomes always smaller than the second output stage NM2.

When the motor 3 is driven at an output smaller than the first intermediate output, the motor control unit 17 changes the preset first output stage NM1 according to the operation of the first operation unit 13 or the second operation unit 14. When the motor 3 is driven at an output equal to or higher than the first intermediate output and smaller than the second intermediate output, the motor control unit 17 changes the preset second output stage NM2 according to the operation of the first operation unit 13 or the second operation unit 14.

In detail, the motor control section 17 decreases the first output stage NM1 by 1 stage each time the first operation section 13 is operated and increases the first output stage NM1 by 1 stage each time the second operation section 14 is operated when the motor 3 is driven at an output stage smaller than the first output stage NM1. The motor control unit 17 decreases the second output stage NM2 by 1 stage each time the first operation unit 13 is operated and increases the second output stage NM2 by 1 stage each time the second operation unit 14 is operated when the motor 3 is driven by an output stage equal to or higher than the first output stage NM1 and smaller than the second output stage NM2. The motor control unit 17 may perform the following control: the first output stage NM1 is increased by 1 stage each time the first operation section 13 is operated, and the first output stage NM1 is decreased by 1 stage each time the second operation section 14 is operated. The second output stage NM2 is also the same.

The motor control unit 17 stops the motor output when the fishing line fed from the spool 2 reaches the stop line length, and resets the first output stage NM1 and the second output stage NM2, which are changed by the operation of the first operation unit 13 or the second operation unit 14, to the first output stage NM1 and the second output stage NM2 set in advance. The stop line length is a line length for stopping the motor output, and is set to a position where the hook assembly attached to the fishing line is easily gripped, for example. The motor control unit 17 sets the line length when the third operation unit 15 is long, for example, as the stop line length.

In this electric reel 100, if the stage N of motor output is smaller than the first output stage NM1, the stage N of motor output is not increased to be higher than the first output stage NM1 even if the first pressing portion 11 is pressed. Therefore, when the motor output is smaller than the first output stage NM1, for example, even if the first pressing portion 11 is pressed with the first pressing force that is the expected or higher, the motor output is limited not to exceed the first output stage NM1. This can prevent the motor output from increasing above the output expected by the angler.

In addition, if the stage N of the motor output is the first output stage NM1 or more and smaller than the second output stage NM2, the motor output is not increased to the second output stage NM2 or more even if the first pressing portion 11 is pressed. Therefore, when the motor output is changed in a range of the first output stage NM1 or more and smaller than the second output stage NM2 in combination with the pulling force of the fish, for example, even if the first pressing portion 11 is pressed with the first pressing force that is expected or more, the motor output is limited not to exceed the second output stage NM2. That is, the motor output can be suppressed from reaching the vicinity of the maximum output. Thus, when the motor output is changed in conjunction with the pulling force of the fish, it is possible to suppress the breakage of the fishing line and the operation of the circuit breaker by applying a large load to the electric reel 100.

< other embodiments >

While the embodiment of the present invention has been described above, the present invention is not limited to the embodiment, and various modifications can be made without departing from the spirit of the invention.

Fig. 7 shows a characteristic C3 of the increase/decrease control mode of the motor control process according to the modification example. In the modification, the motor control unit 17 performs motor control processing in a range from the second output stage NM2 to the stage Nmax, unlike the embodiment. Otherwise, the same as in the above embodiment is applied.

As shown in fig. 7, the increasing/decreasing control mode is to increase the motor output in comparison with the second intermediate output according to the first pressing force P1 when the first pressing unit 11 is pressed while maintaining the output stage of the motor 3 at the second intermediate output (here, the second output stage NM 2), and to decrease the motor output to the second intermediate output when the pressing operation on the first pressing unit 11 is stopped while the motor output exceeds the second intermediate output.

In the increase/decrease control mode, the motor control unit 17 increases the motor output according to an increase in the first pressing force P1, and decreases the motor output to the second intermediate output according to a decrease in the first pressing force P1.

In the increase/decrease control mode, the output stage of the motor 3 is increased as compared with the second output stage NM2 in accordance with the first pressing force P1 only during the pressing operation of the first pressing portion 11, and the motor output is reduced to the second intermediate output when the pressing operation of the first pressing portion 11 is not performed, so that the output stage of the motor 3 is maintained at the second output stage NM2.

The motor control unit 17 releases the increase/decrease control mode when the output stage of the motor 3 is decreased compared to the second output stage NM2 in response to the pressing operation of the second pressing unit 12 in the increase/decrease control mode.

As shown in fig. 8, the display control unit 18 causes the display unit 10 (an example of a notification unit) to display that 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 released, the display control unit 18 stops the display unit 10 from displaying Boost. The notification method for notifying the execution of the increase/decrease control may be other methods such as light, sound, or vibration.

Further, the modification is a configuration in which the increase/decrease control mode is executed in a range from the second output stage NM2 to the stage Nmax. However, for example, the increase/decrease control mode may be performed in a range from the first output stage NM1 to the second output stage NM2. In this case, the maximum output stage in the increase/decrease control mode reaches the second output stage NM2. That is, in the increase/decrease control mode, the upper limit of the output stage may be set. After reaching the second output stage NM2, the same motor control process as in the embodiment is performed. The maximum output stage in the increase/decrease control mode may be an output stage that is smaller than the stage Nmax and different from the second output stage NM2.

The first pressing portion 11 and the second pressing portion 12 can be arranged interchangeably. Alternatively, the functions of the first pressing portion 11 and the second pressing portion 12 may be exchanged with each other in accordance with the operations of the first to third operation portions 13 to 15.

In the above embodiment, the motor output is adjusted by the two pressing portions, that is, the first pressing portion 11 and the second pressing portion 12, but for example, one pressing portion that can be switched to two modes, that is, an output increasing mode in which the motor output is increased and an output decreasing mode in which the motor output is decreased may be provided to adjust the motor output.

The pressure sensors 11a and 12a may be output based on a minute displacement amount generated by a member pressed by a spring having a relatively large spring constant, instead of a single member such as a pressure sensitive element.

In the above embodiment, the rotation speed of the spool 2 is detected as the motor output to perform feedback control, but the current value supplied to the motor 3 may be controlled so that the winding torque becomes a predetermined value. Alternatively, the winding diameter of the spool 2 may be calculated and controlled so that the tension becomes a predetermined value.

The control method for rotating the motor 3 based on the electric signals output from the pressure sensors 11a and 12a in the above embodiment may be arbitrarily selected from control at a predetermined spool rotation speed and control at a predetermined torque value.

In the above embodiment, when the range of the lower limit value and the upper limit value of the pressing force output from the pressure sensors 11a and 12a is divided into any stages, the range may not be equally divided. The range of the pressing force corresponding to the stage having the lower number of stages of increase and decrease of the output stage of the motor 3 may be larger than the range of the higher stage.

In the above embodiment, the lower limit value and the upper limit value (for example, the lower limit value is 30 g and the upper limit value is 2 kg) of the pressing force detected by the pressure sensors 11a and 12a are set in advance, but the lower limit value or the upper limit value, that is, the threshold value of the pressing force may be set arbitrarily by the angler. At this time, when the first pressing portion 11 and the second pressing portion 12 are operated with pressing forces equal to or greater than a predetermined value in a state where the motor 3 is stopped, the operation may be switched to a pressing force setting mode in which a threshold value of the pressing force is set.

In the above embodiment, whether or not there is an operation on the first pressing portion 11 is determined, and whether or not there is an operation on the second pressing portion 12 is determined, but the output of both the pressure sensor 11a and the pressure sensor 12a may be compared, and the pressing operation whose output is larger, that is, whose pressing force is larger, may be determined to be effective.

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