[0002] Patent Document 1 discloses a motor control device for an electric reel that increases motor output based on a pressing operation of a pressing part. When the motor output of Patent Document 1 is increased, if the motor output is about to exceed an intermediate output, the motor control device temporarily limits the motor output to the intermediate output. This prevents the motor output from increasing above the output desired by the angler. [Previous Technical Documents] [Patent Literature]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2021-016316 Summary of the Invention

[0004] [The problem the invention aims to solve]

[0005] In Patent Document 1, after limiting the motor output to an intermediate level, the motor output is increased or decreased by pressing the first and second pressing operation units. When the angler adjusts the motor output relative to the fish's pull, the motor output is usually changed to an output above the intermediate level. Therefore, it is preferable that after the motor output reaches the intermediate level, the motor output can be adjusted flexibly relative to the fish's pull.

[0006] The present invention addresses the issue of providing a motor control device for an electric reel that can flexibly adjust the motor output above the intermediate output. [Technical means to solve the problem]

[0007] One aspect of the electric cable reel of the present invention relates to a motor control device that uses a motor to drive a cable reel spool that is rotatably mounted on the cable reel body. The motor control device includes a first pressing part and a motor control unit. The first pressing part is provided on the cable reel body for pressing operations. The motor control unit increases the motor output based on at least one of a first pressing force and a pressing time. The motor control unit performs the following increase / decrease control: when the first pressing part is pressed while the motor output is at or above the intermediate output (below maximum output), the motor output increases above the intermediate output based on the first pressing force; when the pressing operation on the first pressing part is stopped, the motor output decreases back to the intermediate output.

[0008] In the motor control device of this electric reel, when the motor output is at or above the intermediate output level, the motor output can be increased or decreased according to the pressing operation of the first pressing part. When the pressing operation of the first pressing part is stopped, the motor output is maintained at the intermediate output level. Therefore, the motor output above the intermediate output level can be adjusted flexibly. Furthermore, when the motor output is at or above the intermediate output level, the motor output can be adjusted intuitively.

[0009] The motor control unit can also increase the motor output by increasing the first pressing pressure and decrease the motor output to a second intermediate output by decreasing the first pressing pressure. In this case, the motor output can be adjusted using more intuitive operation.

[0010] The motor control unit may further be provided in the second pressing section of the reel body 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 operation. In this case, it can prevent the motor output from increasing beyond the angler's desired output, and the adjustment of the motor output becomes easier.

[0011] The motor control unit can also limit the motor output to the intermediate output until the pressing operation of the first pressing part stops when the motor output exceeds the intermediate output from the state that has never reached the intermediate output. If the motor output is below the intermediate output when the pressing operation of the first pressing part stops, the motor output at the time when the pressing operation of the first pressing part stops is maintained. In this case, the adjustment of the motor output becomes easy.

[0012] The upper limit output of the motor in the increase / decrease control can also be set to be less than the maximum output of the motor. In this case, it can prevent the motor output from increasing beyond the output desired by the angler.

[0013] The motor control device may further include a notification unit that notifies the motor control unit of the increase or decrease control being performed. In this case, it is easy to know that an increase or decrease control is being performed.

[0014] The motor control unit may further include an operating section installed on the reel body. The motor control unit can also control the motor output in stages from a stopped state to maximum output. When the motor is driven at an output below the intermediate output level, the motor control unit can also change the set value of the output stage corresponding to the intermediate output level based on the operation of the operating section. In this case, the set value of the output stage corresponding to the intermediate output level can be easily changed while the motor is being driven.

[0015] The motor control unit can also stop the motor output when the fishing line wound from the spool reaches the stop length, and reset the set value of the output stage corresponding to the intermediate output, which was changed by the operation unit, to the preset value. In this case, operability is improved.

[0016] The motor control unit may further include a pressure sensor for detecting the first pressing pressure. During increment / decrement control, the motor control unit can, based on the first pressing pressure, progressively control the motor output within a range from a stage one stage larger than the intermediate output stage to the stage corresponding to the maximum output stage. The first pressing pressure corresponding to each stage from the stage one stage larger than the intermediate output stage to the stage corresponding to the maximum output stage can also be divided within the range from the lower limit to the upper limit of the first pressing pressure detected by the pressure sensor. In this case, the motor output stage can be adjusted quickly and easily.

[0017] Another aspect of the present invention involves a motor control device of an electric reel that drives a reel drum rotatably mounted on a reel body having a first pressing part using a motor to perform the following processing: when the first pressing part is pressed while the motor output is at or above the intermediate output (below the maximum output), the motor output is increased above the intermediate output based on the pressing operation of the first pressing part; when the pressing operation of the first pressing part is stopped, the motor output is reduced to the intermediate output. [Effects of the Invention]

[0018] According to the present invention, a motor control device for an electric reel can be provided that is capable of flexibly adjusting the motor output above the intermediate output. Simple Explanation of the Diagram

[0020] As shown in Figure 1, the electric cable reel 100 obtained by one embodiment of the present invention is an electric cable reel driven by a motor using power supplied by an external power source.

[0021] The electric cable reel 100 includes a cable reel body 1, a cable reel 2, a motor 3, a hand operation unit 4, a counter housing 5, a first pressing unit 11, a second pressing unit 12, and a motor control unit 17. The first pressing unit 11, the second pressing unit 12, and the motor control unit 17 constitute part of the motor control device.

[0022] The cable reel body 1 has a frame 6, a first side housing 7 covering one side of the frame 6, a second side housing 8 covering the other side of the frame 6, and a front housing (not shown) covering the front of the frame 6. Inside the cable reel body 1, there is a (not shown) leveling mechanism that operates in conjunction with the cable drum 2, or a (not shown) rotation transmission mechanism that transmits the rotation of the motor 3 and the manual operation unit 4 to the cable drum 2.

[0023] The cable reel 2 is disposed inside the cable reel body 1. The cable reel 2 is mounted on the cable reel body 1 between the first side housing 7 and the second side housing 8, and can rotate freely.

[0024] 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.

[0025] The hand operating part 4 is supported on the first side housing 7 with free rotation.

[0026] The counter housing 5 is disposed on the upper part of the cable reel body 1. The counter housing 5 is fixed to the frame 6. The counter housing 5 is provided with a display unit 10 having a liquid crystal 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 various settings of 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 touch panels provided on the display unit 10. A control unit 16 for performing various controls is housed inside the counter housing 5 (see Figure 2).

[0027] The first pressing part 11 and the second pressing part 12 are provided on the 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.

[0028] As shown in Figure 2, 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 components. 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 part 11 or the pressing operation of the second pressing part 12 via a motor drive circuit 19 that performs PWM driving on the motor 3.

[0029] The control unit 16 is connected to a first pressing unit 11, a second pressing unit 12, and first to third operation units 13 to 15. Furthermore, the control unit 16 is connected to a display unit 10, a spool sensor 20 for detecting the rotation speed and direction of rotation of the spool 2, and a memory unit 21. The memory unit 21 is, for example, a non-volatile memory, storing various setting information of the electric reel 100, such as information on the support position and the stop position of the hull edge.

[0030] The motor control unit 17 controls the motor output in stages from a stopped state to maximum output. The motor control unit 17 increases the motor output (e.g., the rotational speed of 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 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.

[0031] The motor control unit 17 performs the following increase / decrease control: when the motor output is above the intermediate output (below the maximum output), pressing the first pressing part 11 increases the motor output above the intermediate output according to the first pressing force; when the pressing operation of the first pressing part 11 is stopped, the motor output decreases to the intermediate output. The intermediate output is any output that is greater than the output in the stopped state and less than the maximum output.

[0032] In the increase / decrease control, the motor control unit 17 increases the motor output according to the increase of the first pressing force, and decreases the motor output to the intermediate output according to the decrease of the first pressing force.

[0033] When the pressing operation of the first pressing part 11 causes the motor output to exceed the intermediate output from a state that has never reached the intermediate output, the motor control unit 17 limits the motor output to the intermediate output until the pressing operation of the first pressing part 11 stops. When the motor output at the time the pressing operation of the first pressing part 11 stops is below the intermediate output, the motor control unit 17 maintains the motor output at the time the pressing operation of the first pressing part 11 stops. Furthermore, the motor control unit 17 can also limit the motor output to the first intermediate output until the pressing operation of the first pressing part 11 stops when the pressing operation of the first pressing part 11 causes the motor output to change from a state that has never reached the first intermediate output to a state that exceeds the first intermediate output.

[0034] When the motor output of the motor control unit 17 is below the intermediate output when the pressing operation of the second pressing unit 12 is stopped, the motor output of the motor control unit 17 is maintained at the same level as when the pressing operation of the second pressing unit 12 is stopped.

[0035] Next, following the flowcharts shown in Figures 3 and 4, 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 will be described. Here, the motor output is adjusted in stages to a plurality of stages from 0 to Nmax (Nmax+1 stages). Stage 0 is the stopped state of the motor 3, and stage Nmax is the state in which the motor 3 is driven at maximum output. For example, the motor output is adjusted to 31 stages.

[0036] Furthermore, here, a lower limit and an upper limit value for the pressing force output from pressure sensors 11a and 12a are set (for example, a lower limit of 30 grams and an upper limit of 2 kilograms). Moreover, based on dividing the range of these lower and upper limits into any number of stages (for example, thirty-one equal parts), the increment and decrement of the motor output stages corresponding to each stage are set. Furthermore, it is preferable to pre-set that the greater the pressing force, the greater the increment and decrement of the motor output stages.

[0037] Furthermore, motor 3 is controlled here using PWM, with a maximum output of 100% duty cycle. The motor output is, for example, the rotational speed of motor 3. Moreover, when a load is applied causing the rotational speed of the winding drum 2 to decrease, feedback control is implemented to maintain a specific rotational speed.

[0038] First, in step S1, it is determined whether the first pressing force P1, which applies pressure to the first pressing part 11, is 30 g or more. Specifically, for example, it is determined whether the first pressing part 11 is pressed by a pressing force of 30 g or more by detecting the output of the pressure sensor 11a from the first pressing part 11. When only an output of less than 30 g is detected for the first pressing force P1, in order to avoid false operation, it is considered that the first pressing part 11 has not been pressed and the output is ignored. Furthermore, for example, a resistive film type pressure sensor is used here, and the circuit is configured so that the output voltage is proportional to the pressing force.

[0039] If it is determined in step S1 that the first pressing force P1 is 30 g or more, proceed to step S2. In step S2, read the current motor output stage (hereinafter referred to as stage N).

[0040] In step S3, it is determined whether stage N is an intermediate stage NM or higher corresponding to the intermediate output. The intermediate stage NM is preferably a stage within the range of stage 5 to 15. The intermediate output is, for example, set to approximately half of the maximum output. Therefore, in this embodiment, the intermediate stage NM is, for example, set to stage 16. Furthermore, the motor output corresponding to the intermediate stage NM is preferably set to an output within the range of 30% to 80% of the maximum output. The motor output corresponding to the intermediate stage NM is preferably set to an output within the range of 40% to 70% of the maximum output.

[0041] In step S4, it is determined whether the first pressing force P1 is less than 2 kg. If it is determined in step S4 that the first pressing force P1 is greater than 2 kg, proceed to step S12 and set stage N to stage Nmax. That is, increase the motor output to the maximum output. Then, proceed to the next step S10 and maintain the motor output at stage Nmax.

[0042] Furthermore, when the motor output is maintained at stage Nmax, and the first pressing part 11 is pressed by the first pressing force P1 of 2 kg or more, step S12 is entered. However, since the motor output has already been maintained at stage Nmax, the result is to continue to maintain the motor output at stage Nmax.

[0043] When it is determined in step S4 that the first pressing pressure P1 has not reached 2 kg, step S5 is entered, and the preset stage increase number M for the output of the pressure sensor 11a is read from the memory unit 21.

[0044] In step S6, it is determined whether the result of adding the stage increment M to stage N has not reached Nmax. If Nmax has not been reached, proceed to step S7 and set N+M as stage N. That is, increase the motor output to stage N+M. Specifically, for example, when the first pressing part 11 is pressed by a first pressing force P1 of 300 g to 400 g while the motor output is in stage 22, add a pre-set stage increment 2 corresponding to the range of the first pressing force P1 to stage 22, and set the resulting stage 24 as stage N. Then, proceed to step S8.

[0045] If, in step S6, it is determined that the sum of the current stage N and the stage increment M is greater than or equal to Nmax, then proceed to step S11, where stage Nmax minus one stage is set as stage N. That is, as long as the first pressing force P1 on the first pressing part 11 does not exceed 2 kg, stage N will not become stage Nmax. Afterward, proceed to step S8.

[0046] In step S8, for example, wait 0.5 seconds before proceeding to step S9.

[0047] In step S9, it is determined, similarly to step S1, whether the first pressing force P1 is 30 g or more. That is, it is determined whether the first pressing part 11 is still being pressed by the first pressing force P1 of 30 g or more. If the first pressing part 11 is being pressed by the first pressing force P1 of 30 g or more, then return to step S2. If the first pressing part 11 is not being pressed by the first pressing force P1 of 30 g or more, then proceed to step S10, and maintain the motor output at the stage N set in step S7 or step S11.

[0048] If it is determined in step S1 that the first pressing force P1 is less than 30 g, proceed to step S13.

[0049] In step S13, based on the output from the pressure sensor 12a, it is determined whether the second pressing force P2, which is used to press the second pressing part 12, is 30 g or more. If only an output of less than 30 g is detected for the second pressing force P2, in order to avoid misoperation, it is considered that the second pressing part 12 has not been pressed and the output is ignored.

[0050] If it is determined in step S13 that the second pressing force P2 is 30 g or more, proceed to step S14 to determine whether stage N is 1 or more, i.e., whether motor 3 is being driven. If stage 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 stage N is 1 or more, proceed to step S15.

[0051] In step S15, it is determined whether the second pressing force P2 is less than 2 kg. If the second pressing force P2 is 2 kg or more, proceed to step S23 and change stage N to 0. That is, stop the drive of motor 3.

[0052] If it is determined in step S15 that the second pressing force P2 has not reached 2 kg, proceed to step S16 and read stage N. Then proceed to step S17.

[0053] In step S17, the preset stage reduction number L for the output of pressure sensor 12a is read from memory unit 21, and then the process proceeds to step S18.

[0054] In step S18, it is determined whether the result of subtracting the stage reduction number L from stage N is greater than or equal to 1. If the result of subtracting the stage reduction number L from stage N is greater than or equal to 1, proceed to step S19 and set NL to stage N. That is, reduce the motor output to stage NL. Then proceed to step S20.

[0055] If, in step S18, the result of subtracting the stage reduction number L from stage N is less than 1, proceed to step S22 to change stage N to 1. Then proceed to step S20.

[0056] In step S20, for example, wait 0.5 seconds before proceeding to step S21.

[0057] In step S21, similar to step S13, it is determined whether the second pressing force P2 is 30 g or more. That is, it is determined whether the second pressing part 12 is still being pressed by the second pressing force P2 of 30 g or more. If the second pressing part 12 is being pressed by the second pressing force P2 of 30 g or more, then return to step S15. If the second pressing part 12 is not being pressed by the second pressing force P2 of 30 g or more, then proceed to step S10, and maintain the motor output at the stage N set in step S19 or step S22.

[0058] Next, referring to Figure 4, the motor control process when it is determined in step S3 that stage N has not reached the intermediate stage NM will be explained. When it is determined in step S3 that stage N has not reached the intermediate stage NM, step S31 is entered.

[0059] In step S31, the preset stage increment number M for the output of pressure sensor 11a is read from memory unit 21. Then, step S32 is performed.

[0060] In step S32, it is determined whether the result of adding the stage increment M to stage N is greater than the intermediate stage NM. If, in step S32, the result of adding the stage increment M to stage N is less than or equal to the intermediate stage NM, the process proceeds to step S36, where the result of adding the stage increment M to stage N is set as the new stage N. Then, the process proceeds to step S8.

[0061] Furthermore, in step S32, it can also be determined whether the result of adding the stage increment M to stage N is above the intermediate stage NM. That is, in step S32, if it is determined that the result of adding the stage increment M to stage N is above the intermediate stage NM, then proceed to step S33; if it is determined that the result of adding the stage increment M to stage N does not reach the intermediate stage NM, then proceed to step S36.

[0062] When the sum of stage N and stage increment M obtained in step S32 is greater than the intermediate stage NM, proceed to step S33. In step S33, the intermediate stage NM is set as stage N. That is, the motor output is limited to the intermediate stage NM such that stage N does not exceed the intermediate stage NM. Then, proceed to step S34.

[0063] In step S34, for example, wait 0.5 seconds before proceeding to step S35.

[0064] In step S35, similar to step S9, it is determined whether the first pressing part 11 is still being pressed by a first pressing force P1 of 30 g or more. If the first pressing part 11 is being pressed by a first pressing force P1 of 30 g or more, the process returns to step S33. That is, even if the first pressing part 11 is still being pressed by a first pressing force P1 of 30 g or more, the motor output is maintained at the intermediate stage NM. If the first pressing part 11 is not being pressed by a first pressing force P1 of 30 g or more in step S35, the process proceeds to step S37.

[0065] In step S37, the motor output is controlled in the increase / decrease control mode. The increase / decrease control mode has the characteristics represented by the chain line C2 in Figure 5. In Figure 5, the horizontal axis represents the first pressing force P1, and the vertical axis represents stage N. Furthermore, the chain line C1 indicates the characteristic of limiting the motor output to the intermediate stage NM.

[0066] The increase / decrease control mode refers to the following: when the first pressing part 11 is pressed while the output stage of motor 3 is maintained at the intermediate stage NM, the motor output is increased from the intermediate stage NM 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 intermediate stage NM, the motor output is reduced to the intermediate stage NM.

[0067] In the increase / decrease control mode, the output stage of motor 3 increases according to the increase of the first pressing force P1, and the output stage of motor 3 decreases to the intermediate stage NM according to the decrease of the first pressing force P1. In the increase / decrease control mode, only during the period when the first pressing part 11 is pressed, the output stage of motor 3 increases from the intermediate stage NM according to the first pressing force P1, and when the first pressing part 11 is not pressed, the output stage of motor 3 decreases to the intermediate stage NM, and the output stage of motor 3 is maintained at the intermediate stage NM.

[0068] In this embodiment, the first pressing pressure P1 corresponding to each stage from the stage one stage larger than the intermediate stage NM to the stage corresponding to the maximum output is divided within the range from the lower limit to the upper limit of the first pressing pressure P1 detected by the pressure sensor 11a, and the output stage of the motor 3 is increased or decreased according to the first pressing pressure P1.

[0069] When the motor control unit 17 deactivates the increase / decrease control mode in which the output stage of the motor 3 decreases from the intermediate stage NM due to the pressing operation of the second pressing unit 12, the increase / decrease control mode is deactivated. Specifically, in step S38, the output of the pressure sensor 11a is used to determine whether the first pressing force P1 is 30 g or more. If it is determined that the first pressing force P1 is 30 g or more, the increase / decrease control mode is maintained, and the output stage of the motor 3 is controlled in this mode. If it is determined in step S38 that the first pressing force P1 is less than 30 g, the process proceeds to step S39.

[0070] In step S39, it is determined whether the second pressing force P2 is 30 g or more. If it is determined that the second pressing force P2 is 30 g or more, the process proceeds to step S15, where the output stage of motor 3 is reduced. This deactivates the increase / decrease control mode. If it is determined in step S39 that the second pressing force P2 is less than 30 g, the increase / decrease control mode is maintained.

[0071] As shown in Figure 6, 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 increment / decrease control mode. When the increment / decrease control mode is executed, the display control unit 18 causes the display unit 10 to display, for example, "Boost". When the increment / 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 increment / decrease control, other methods such as light, sound, or vibration may also be used.

[0072] The motor control unit 17 can set the intermediate stage NM to any output stage based on the operation of the first operation unit 13. The intermediate stage NM is set when the motor output is stopped, for example, by operating the first operation unit 13 to switch to the intermediate stage NM setting mode. At this time, the display control unit 18 causes the display unit 10 to display the intermediate stage NM setting mode. Then, for example, by pressing the second operation unit 14 or the third operation unit 15, any stage is selected as the intermediate stage NM, and the first operation unit 13 is operated again to set the intermediate stage NM to the selected stage.

[0073] When the motor 3 is driven with an output that has not reached the intermediate stage NM, the motor control unit 17 changes the preset value of the intermediate stage NM according to the operation of the first operation unit 13 or the second operation unit 14.

[0074] In detail, when the motor 3 is driven at an output stage below the intermediate stage NM, the motor control unit 17 decreases the intermediate stage NM by one stage whenever the first operation unit 13 is operated, and increases the intermediate stage NM by one stage whenever the second operation unit 14 is operated. Furthermore, the motor control unit 17 can also perform the following control: increase the intermediate stage NM by one stage whenever the first operation unit 13 is operated, and decrease the intermediate stage NM by one stage whenever the second operation unit 14 is operated.

[0075] When the fishing line wound from the spool 2 reaches the stop line length, the motor control unit 17 stops the motor output and resets the intermediate stage NM setting value changed by the operation of the first operation unit 13 or the second operation unit 14 to the preset intermediate stage NM. The stop line length is the line length at which the motor output stops, for example, set to a position that is easy to grip the fishing rig attached to 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.

[0076] In this electric reel 100, when the motor output is at or above the intermediate stage NM, the motor output can be increased or decreased according to the pressing operation of the first pressing part 11. When the pressing operation of the first pressing part 11 is stopped, the motor output is reduced to the intermediate stage NM and maintained at the intermediate stage NM. Therefore, the motor output at or above the intermediate stage NM can be adjusted flexibly. Furthermore, when the motor output is at or above the intermediate stage NM, the motor output can be adjusted by intuitive operation.

[0077] <Other Implementation Methods> The above describes one embodiment of the present invention, but the present invention is not limited to the above embodiment and various modifications can be made without departing from the spirit of the invention.

[0078] In the above embodiment, when the pressing operation of the first pressing unit 11 causes the motor output to exceed the intermediate output from a state that has never reached the intermediate output, the motor control unit 17 restricts the motor output to the intermediate output until the pressing operation of the first pressing unit 11 stops. However, when the pressing operation of the first pressing unit 11 causes the motor output to exceed the intermediate output from a state that has never reached the intermediate output, it is not necessary to restrict the motor output to the intermediate output.

[0079] Figure 7 is a diagram illustrating the characteristics of the motor control unit in the first variation. The motor control unit 17 can 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 causes the motor output to change from a state that has never reached the first intermediate output to an intermediate output or higher, and also causes the motor output to change from a state that has never reached the second intermediate output to a second intermediate output or higher. The second intermediate output is any output between the first intermediate output and the maximum output.

[0080] That is, the motor control unit 17 may also have the characteristics indicated by the chain line C3 in FIG7. The motor control unit 17 may also limit the motor output to the second intermediate stage NM2 until the pressing operation of the first pressing unit 11 stops when the pressing operation of the first pressing unit 11 causes the output stage of the motor 3 to exceed the second intermediate stage NM2, which corresponds to the second intermediate output. In this case, the motor control unit 17 controls the motor output in the increment / decrement control mode within the range from the second intermediate stage NM2 to stage Nmax.

[0081] Furthermore, as shown in Figure 8, the upper limit of motor output can also be set in the increase / decrease control mode. In the increase / decrease control mode, the upper limit output of motor 3 is set to be less than the maximum output of motor 3. For example, the increase / decrease control mode can also be executed within the range from the intermediate stage NM to the second intermediate stage NM2. In this case, the upper limit output stage in the increase / decrease control mode becomes the second intermediate stage NM2. In the increase / decrease control mode, after the output stage of motor 3 reaches the second intermediate stage NM2 due to the pressing operation of the first pressing part 11, the output of motor 3 can be maintained at the second intermediate stage NM2. When the pressing operation of the first pressing part 11 is stopped and the first pressing part 11 is pressed again, the output of motor 3 increases compared to the second intermediate stage NM2. Moreover, the upper limit of motor output in the increase / decrease control mode can also be an output stage different from the second intermediate stage NM2.

[0082] 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 according to the operation of the first to third operating parts 13 to 15.

[0083] In the above embodiment, the motor output is adjusted by two pressing parts, the first pressing part 11 and the second pressing part 12. However, for example, a pressing part that can switch between two modes, namely 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.

[0084] 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.

[0085] In the above embodiments, the rotational speed of the winding drum 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 specific value. Alternatively, the winding diameter of the winding drum 2 can be calculated to control the tension to a specific value.

[0086] Regarding the control method in the above embodiment that causes the motor 3 to rotate based on the electrical signals output from the pressure sensors 11a and 12a, either the control method can be selected from two methods: control with a specific drum speed or control with a specific torque value.

[0087] In the above embodiments, when the range of the lower and upper limits of the pressing force output from the pressure sensors 11a and 12a is divided into arbitrary stages, the range may not be divided equally. Alternatively, the range of pressing force corresponding to the stage with the lower increase and decrease in the output stage of the motor 3 may be larger than the range of the higher stage.

[0088] In the above embodiment, the lower limit and upper limit of the pressing force detected by the pressure sensors 11a and 12a are preset (for example, the lower limit is 30 grams and the upper limit is 2 kilograms). However, it can also be set so that the angler can arbitrarily set the lower limit or upper limit, i.e., the threshold of the pressing force. In this case, it can also be set to switch to the pressing force setting mode when the first pressing part 11 and the second pressing part 12 are operated with a pressing force of a certain amount or more while the motor 3 is stopped.

[0089] In the above embodiment, 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, the outputs of the pressure sensor 11a and the pressure sensor 12a can also be compared, and the one with the larger output, that is, the one with the larger pressing force, can be judged as a valid pressing operation.

[0090] Alternatively, the program used to implement the motor control processing of the motor control unit 17 can be recorded in a recording medium that can be read by a computer. For example, the CPU (Central Processing Unit) can execute the program recorded in the recording medium to perform motor control processing.
