[Problems to be Solved by the Invention]

Since the operation part of Patent Document 1 adjusts the rotational speed of the motor according to the pressing force, it is difficult to increase or decrease the pressing force especially when the speed is slightly accelerated or decelerated. Therefore, when the speed is to be finely adjusted, a pressing force exceeding the intention is generated, and the acceleration/deceleration of the rotational speed of the motor may become abrupt. Furthermore, in the speed adjustment switch of Patent Document 2, since the rotational speed of the motor is changed according to the operation time of the switch, it is difficult to obtain the desired rotational speed of the motor quickly and easily.

The subject of this invention is to adjust the output of a motor quickly and easily with respect to the motor control apparatus of an electric reel. [means to solve the problem]

Preferably, the motor control means increases or decreases the output of the motor only by a predetermined value at a time interval set corresponding to the pressing force in the second time range exceeding the first time range. In this case, in the second time range, for example, the output of the motor including the fine adjustment can be easily adjusted by increasing or decreasing the output of the motor by a predetermined value at shorter time intervals as the pressing force increases. .

Preferably, the motor control means increases or decreases the output of the motor only by a predetermined value at a time interval set corresponding to the pressing force within the first time range whose duration exceeds the predetermined time range. In this case, in the first time range, for example, the output of the motor including the fine adjustment can be easily adjusted by increasing or decreasing the output of the motor by a predetermined value at shorter time intervals as the pressing force increases. .

The operation lever 4 is rotatably supported by the lower center portion of the first side cover 7a. In addition, the clutch operating member 9 is swingably arranged above the support portion of the operating lever 4 . The clutch operating member 9 is a member for turning ON and OFF a clutch (not shown) provided between the motor 3 , the operating lever 4 , and the spool 2 .

The meter case 5 is arranged on the upper part of the front side of the reel main body 1 , and is fixed to the first side plate 6 a and the second side plate 6 b constituting the frame 6 . The upper surface part of the meter counter case 5 is provided with the display part 10 which has a liquid crystal display. On the rear side of the display unit 10 , as shown in FIGS. 1 and 2 , a first pressing operation unit 11 , a second pressing operation unit 12 , and a first pressing operation unit 11 and a second pressing operation unit 12 , and the meter counter case 5 protruding upward are arranged. 3 operation switches 13. In the present embodiment, the first and second pressing operation parts 11 and 12 are arranged offset from the center in the left-right direction toward the opposite side to the operation lever 4 . In addition, the first push operation portion 11 and the second push operation portion 12 are arranged adjacent to each other in the vertical direction. The three operation switches 13 are mainly used for various settings of the electric cord reel 100 . Inside the meter case 5, the control part 21 (refer FIG. 3) which performs various control is accommodated.

As shown in FIG. 3, the 1st and 2nd push operation parts 11 and 12 have pressure sensors 11a and 12a, respectively. The pressure sensors 11a and 12a are means for outputting electrical signals corresponding to the level of the force (hereinafter referred to as the pressing force) for pressing the first and second pressing operation parts 11 and 12, and detect the magnitude corresponding to the pressing force. The value is output to the motor control unit 22 of the control unit 21 described later as an electrical signal.

As shown in FIG. 3 , the control unit 21 has a functional configuration including a motor control unit 22 that controls the motor 3 and a display control unit 23 that controls the display unit 10 . The motor control unit 22 is a motor drive circuit 24 that drives the motor 3 through PWM, and controls the drive of the motor 3 in accordance with the pressing operations of the first and second pressing operation units 11 and 12 . Specifically, the motor control unit 22 controls the output of the motor 3 (hereinafter referred to as motor output) according to the duration and the pressing force of the pressing of the first pressing operation unit 11 or the second pressing operation unit 12 . In the present embodiment, the motor control unit 22 increases the motor output according to the pressing force while the first pressing operation unit 11 is being pressed, and decreases the motor output according to the pressing force while the second pressing operation unit 12 is being pressed. In addition, the motor control unit 22 maintains the motor output when the pressing of the first pressing operation unit 11 or the second pressing operation unit 12 is stopped.

The control unit 21 is connected to the first and second push operation units 11 and 12 and the operation switch 13 . In addition, the control unit 21 is connected to the display unit 10 , the reel sensor 25 for detecting the rotational speed and the rotational direction of the reel 2 , and the memory unit 26 . The memory unit 26 is, for example, a non-volatile memory, and various setting information of the electric reel 100 such as information on the position of the shed (depth of fish migration layer) and information on the stop position of the boat's edge.

<Motor control process> Next, when the power supply of the electric reel 100 is in the ON state, an example of the flow of the motor control process performed by the motor control unit 22 of the control unit 21 is based on FIGS. 4 to 8 . Illustration of the flowchart shown in Fig. Here, the motor output is controlled in steps of Nmax+1 from 0 to Nmax. Stage 0 is a state in which the motor 3 is stopped, and stage Nmax is a state in which the motor 3 is driven by the maximum output.

Furthermore, the lower limit value and the upper limit value of the pressing force output from the pressure sensors 11a and 12a are set (for example, the lower limit value is 30 grams, and the upper limit value is 2 kilograms). Then, the range of the lower limit value and the upper limit value is divided into arbitrary stages (for example, 31 equal divisions), and the number of increases and decreases of the motor output stage corresponding to each stage is set. In addition, it is preferable to set the number of increases and decreases in the motor output stage as the pressing force increases.

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

First, the flow of the motor control process when the first pressing operation part 11 is pressed by the pressing force P1 of 30 g or more will be described with reference to FIGS. 4 , 5 , and 6 .

In step S1, it is determined whether or not the first pressing operation portion 11 is pressed by the pressing force P1 of 30 g or more. Specifically, by detecting, for example, the output from the pressure sensor 11a of the first pressing operation part 11, it is determined whether or not the first pressing operation part 11 is pressed by the pressing force P1 of 30 g or more. If it is determined that the first pressing operation part 11 is pressed by the pressing force P1 of 30 g or more, the process proceeds to step S2. When it is only detected that the pressing force P1 is an output of less than about 30 g, the output is ignored as a non-pressed person in order to avoid erroneous operation. Here, for example, a resistive film type pressure sensor is used, and the circuit is configured so that the output voltage is proportional to the pressing force.

In step S2, the measurement of the duration T1 of the first pressing operation part 11 being pressed is started (hereinafter only referred to as "duration T1"). In addition, the duration T1 here is the time during which the first pressing operation part 11 is continuously pressed by the pressing force P1 of 30 g or more.

In step S3, the current motor output stage N0 is read, and the process proceeds to step S4.

In step S4, it is judged whether or not the motor output stage N0 is less than Nmax. That is, here, it is determined whether or not the current motor 3 is rotated by the maximum output. If it is determined that the rotation is at the maximum output, since the output cannot be increased by more than this, the process proceeds to step S5 and the current motor output is maintained. That is, in this case, the motor output max is maintained. If it is determined that the motor output stage N0 is less than Nmax, the process proceeds to step S6.

In step S6, the motor output stage N0 is set to increase the motor output stage N1 by one stage, and the process proceeds to step S7.

In step S7, it is determined whether or not the motor output stage N1 set in step S6 is less than Nmax. That is, here, it is determined whether or not the current motor 3 is rotated by the maximum output. If it is determined that the motor is rotated at the maximum output, the process proceeds to step S5, and the motor output is maintained at the maximum output. If it is determined that the motor output stage N0 is less than Nmax, the process proceeds to step S8.

In step S8, it is determined whether or not the pressing of the first pressing operation unit 11 is continued. If it is determined that the pressing is not continued, the process proceeds to step S5, and the motor output stage N1 set in step S6 is maintained. If it is determined that the pressing is continued, the process proceeds to step S9.

In step S9, it is determined whether the duration T1 is less than 100 ms. If it is determined that the duration time T1 is less than 100 ms, the process returns to step S8, and it is determined whether or not the pressing of the first pressing operation unit 11 is continued. If it is determined that the duration T1 is 100 ms or more, the process proceeds to step S10 shown in FIG. 5 .

In step S10, the pressing force P1 of the first pressing operation part 11 is detected, and the process proceeds to step S11.

In step S11, the number M1 of stage increments corresponding to the motor output stage of the pressing force P1 detected in step S10 is read out from the memory unit 26, and the process proceeds to step S12.

In step S12, it is determined whether or not the motor output stage N0 read in step S3 shown in FIG. 4 plus the stage increment number M1 is less than Nmax. When Nmax is greater than or equal to Nmax, the process proceeds to step S13, and the current motor output stage N1 is set to Nmax. Then, it moves to step S5 shown in FIG. 4, and the present motor output is maintained. That is, in this case, the motor output max is maintained. In step S12, if the step increase number M1 is added to the motor output phase N0 and the result is less than Nmax, the process proceeds to step S14.

In step S14, the motor output stage in which the motor output stage N0 read in step S3 is increased by the stage increment number M1 is set as a new motor output stage N1. Specifically, for example, when the motor output stage N0 is "4" and the first pressing operation part 11 is pressed by the pressing force P1 of 300 g to 400 g, the range of the pressing force P1 is added with the step increment number set in advance. (eg "5"), set the motor output stage N1 to "9". Then, it moves to step S15.

In step S15, it is determined whether or not the pressing of the first pressing operation unit 11 is continued. If it is determined that the pressing is not continued, the process proceeds to step S5 shown in FIG. 4 , and the current motor output stage N1 is maintained. If it is determined that the pressing is continued, the process proceeds to step S16.

In step S16, it is determined whether the duration T1 is less than 300 ms. If it is determined that the duration T1 is less than 300 ms, the process proceeds to step S17.

In step S17, the pressing force P1 of the first pressing operation part 11 is detected, and the process proceeds to step S18.

In step S18, the step increment number M2 of the motor output step corresponding to the detected pressing force P1 is read out from the memory unit 26, and the process proceeds to step S19.

In step 19, it is judged whether the motor output stage in which the motor output stage N0 read in step S3 is increased by the stage increment number M2 is larger than the current motor output stage N1. If it is judged that it is not larger, it returns to step S15. Specifically, for example, if the motor output stage N0 is "4", the stage increment number M2 is "3", and the current motor output stage N1 is 9, 4(N0)+3(M2)>9(N1) , the current motor output stage N1 is maintained and the process returns to step S15. If it is judged that it is larger, it transfers to step S20. Specifically, for example, when the number of step increments M2 is 7, it becomes 4(N0)+7(M2)>9(N1), and the process proceeds to step S20. That is, when the 1st pressing operation part 11 is pressed further by strong force, it transfers to step S20.

In step S20, it is determined whether or not the motor output stage in which the motor output stage N0 read in step S3 is increased by the stage increment number M2 is less than Nmax. When it is judged that it is less than Nmax, it transfers to step S21.

In step S21, the motor output stage in which the motor output stage N0 read in step S3 is increased by the stage increment number M2 is set as a new motor output stage N1 (eg, "11"), and the process returns to step S15.

In step S20, if it is determined that the motor output phase N0 read in step S3 is increased by the step increase number M2, the motor output phase is Nmax or more, after step S22, the current motor output phase N1 is set to Nmax. Then, it moves to step S5 shown in FIG. 4, and the present motor output is maintained. That is, in this case, the motor output max is maintained.

Here, the pressing of the first pressing operation unit 11 is continued until the duration time T1 is determined to be 300 ms or more in step S16. First, in step S14, the stage increment number M1 read in step S11 is It is added to the motor output stage N0 read in step S3. Next, when the stage increment number M2 read out in step S18 exceeds the stage increment number M1 added in step S14, the motor output stage N1 is reset. After that, when the stage increment number M2 read out in step S18 exceeds the stage increment number M2 added in step S21 again, the motor output stage N1 is reset. That is, every time the pressing force P1 stronger than the pressing force P1 corresponding to the added number of step increments is pressed, the motor output stage N1 is reset, and if the pressing force P1 is small, the step increase up to that is maintained. Number of motor output stages.

If it is determined in step S16 that the duration time T1 is 300 ms or more, the process proceeds to step S26 shown in FIG. 6 .

In step S26, the motor output stage added by one stage to the current motor output stage N1 is set as a new motor output stage N2. Then, it moves to step S27.

In step S27, it is determined whether or not the motor output stage N2 of one stage added in step S26 is less than Nmax. That is, here, it is determined whether or not the current motor 3 is rotated by the maximum output. If it is determined that the motor is rotated at the maximum output, the process proceeds to step S5, and the motor output is maintained at the maximum output. If it is determined that the motor output stage N2 is less than Nmax, the process proceeds to step S28.

In step S28, the duration time T1 is reset, and the measurement of the duration time T1 is started again. Then, it moves to step S29.

In step S29, the pressing force P1 of the first pressing operation part 11 is detected, and the process proceeds to step S30.

In step S30, the time interval TI corresponding to the pressing force P1 detected in step S29 is read out from the memory unit 26, and the process proceeds to step S31. Here, the time interval TI of five stages (10 ms, 30 ms, 50 ms, 100 ms, 300 ms) is set in accordance with the pressing force P1, for example. In addition, the time interval TI is preferably set so that the larger the pressing force P1 is, the shorter the time interval TI is.

In step S31, it is judged whether or not the duration T1 after the measurement is resumed in step S28 exceeds the time interval TI read out in step S30. If it is judged that it exceeds, it returns to step S26, and it sets to the stage which increased the current motor output stage N2 by one stage. If it is judged that it does not exceed, it transfers to step S32.

In step S32, it is determined whether or not the pressing of the first pressing operation unit 11 is continued. If it is determined that the pressing is not continued, the process proceeds to step S5, and the current motor output stage N2 is maintained. If it is determined that the pressing is continued, the process returns to step S29. Here, even if the pressing force P1 changes on the way, the process returns to step S29, the pressing force P1 of the first pressing operation part 11 is detected, and the time interval TI corresponding to the pressing force P1 is read out. Thus, after it is determined in step S16 that the duration T1 is 300 ms or more, the increase speed of the motor output stage N2 can be adjusted only by changing the pressing force P1.

Next, the flow of the motor control process when it is determined in step S1 that the first pressing operation portion 11 is not pressed by the pressing force P1 of 30 g or more will be described with reference to FIGS. 4 , 7 and 8 .

In step S1, if it is determined that the first pressing operation portion 11 is not pressed by the pressing force P1 of 30 g or more, the process proceeds to step S41.

In step S41, it is determined whether or not the second pressing operation portion 12 is pressed by the pressing force P2 of 30 g or more. Specifically, similarly to the first pressing operation part 11 , it is determined whether the second pressing operation part 12 is pressed by the pressing force P2 of 30 g or more by detecting the output from the pressure sensor 12 a of the second pressing operation part 12 . Press. If it is determined that the second pressing operation portion 12 is pressed by the pressing force P2 of 30 g or more, the process proceeds to step S42. When it is only detected that the pressing force P2 is an output of less than about 30 g, the output is ignored as a non-pressed person in order to avoid erroneous operation. Then, it moves to step S5, and the current motor output stage is maintained. Here, for example, a resistive film type pressure sensor is used, and the circuit is configured so that the output voltage is proportional to the pressing force.

In step S42, the measurement of the duration time T2 (hereinafter only referred to as "duration time T2") during which the second pressing operation part 12 is pressed is started. In addition, the duration T2 here refers to the time during which the second pressing operation portion 12 is continuously pressed by the pressing force P2 of 30 g or more.

In step S43, the current motor output stage N0 is read, and the process proceeds to step S44.

In step S44, it is determined whether or not the motor output stage N0 read in step S43 is 1 or more. That is, it is determined whether or not the motor 3 is driven. If the motor output stage N0 is 0, since the operation of the second push operation unit 12 for reducing the output is meaningless, the motor control process is not executed. That is, the state where the motor output 0 is maintained. If it is determined that the motor output stage N0 is 1 or more, the process proceeds to step S45.

In step S45, the motor output stage N0 is set to be the motor output stage N1 reduced by one stage, and the process proceeds to step S46.

In step S46, it is determined whether or not the motor output stage N1 set in step S6 is 1 or more. That is, it is determined whether or not the motor 3 is driven. If the motor output stage N1 is 0, the process proceeds to step S5, and the motor output is maintained at 0. If it is determined that the motor output stage N1 is 1 or more, the process proceeds to step S47.

In step S47, it is determined whether or not the pressing of the second pressing operation unit 12 is continued. If it is determined that the pressing is not continued, the process proceeds to step S5, and the current motor output stage N1 is maintained. If it is determined that the pressing is continued, the process proceeds to step S48.

In step S48, it is determined whether the duration T2 is less than 100 ms. If it is determined that the duration T2 is less than 100 ms, the process returns to step S47. If it is determined that the duration T2 is 100 ms or more, the process proceeds to step S49 shown in FIG. 7 .

In step S49, the pressing force P2 of the second pressing operation part 12 is detected, and the process proceeds to step S50.

In step S50, the step reduction number L1 corresponding to the motor output step of the pressing force P2 detected in step S49 is read out from the memory unit 26, and the process proceeds to step S51.

In step S51, it is determined whether or not the motor output stage N0 read in step S43 shown in FIG. 4 minus the stage reduction number L1 is 1 or more. If it is less than 1, the process proceeds to step S52, and the motor output stage N1 is set to 0. That is, the driving of the motor 3 is stopped. Then, it moves to step S5, and the state of the motor output 0 is maintained. If it is 1 or more, it moves to step S53.

In step S53, the motor output stage obtained by subtracting the stage reduction number L1 from the motor output stage N0 read in step S43 is set as a new motor output stage N1. Specifically, for example, when the motor output stage N0 is "15" and the second pressing operation part 12 is pressed by the pressing force P2 of 300 g to 400 g, the range of the pressing force P2 is reduced by the number of steps set in advance ( For example, "5") is subtracted, and the motor output stage N1 is set to "10". Then, it moves to step S54.

In step S54, it is determined whether or not the pressing of the second pressing operation unit 12 is continued. If it is determined that the pressing is not continued, the process proceeds to step S5, and the current motor output stage N1 is maintained. If it is determined that the pressing is continued, the process proceeds to step S55.

In step S55, it is determined whether the duration T2 is less than 300 ms. If it is determined that the duration T2 is less than 300 ms, the process proceeds to step S56.

In step S56, the pressing force P2 of the second pressing operation part 12 is detected, and the process proceeds to step S57.

In step S57, the step reduction number L2 corresponding to the motor output step of the pressing force P2 detected in step S56 is read out from the memory unit 26, and the process proceeds to step S58.

In step S58, it is determined whether the motor output stage obtained by subtracting the stage reduction number L2 from the motor output stage N0 read in step S43 shown in FIG. 4 is smaller than the current motor output stage N1. If it is determined that the motor output stage is not small, the process returns to step S54. Specifically, for example, when the motor output stage N0 is "15", the stage reduction number L2 is 3, and the current motor output stage N1 is "10", 15(N0)-3(L2)<10(N1) , the current motor output stage N1 is maintained and the process returns to step S54. If it is judged that it is small, it transfers to step S59. Specifically, for example, when the number of step reductions L2 is "7", it becomes 15(N0)-7(L2)<10(N1), and the process proceeds to step S59. That is, when the 2nd pressing operation part 12 is pressed further by strong force, it transfers to step S59.

In step S59, it is determined whether or not the motor output stage obtained by subtracting the stage reduction number L2 from the motor output stage N0 read in step S43 is 1 or more. If it is determined that it is 1 or more, the process proceeds to step S60.

In step S60, the motor output stage obtained by subtracting the stage reduction number L2 from the motor output stage N1 set in step S45 is set as a new motor output stage N1 (eg, "8"), and the process returns to step S54.

In step S59, if it is determined that the motor output stage N0 read in step S43 after subtracting the stage reduction number L2 is less than 1, the process proceeds to step S61, and the motor output stage N1 is set to 0. That is, the driving of the motor 3 is stopped. Then, it moves to step S5, and the state of the motor output 0 is maintained.

Here, the pressing of the second pressing operation unit 12 is continued until it is determined in step S55 that the duration T2 is 300 ms or more. First, in step S53, the step reduction number L1 read in step S50 is The motor output stage N0 read in step S43 is subtracted. Next, when the stage reduction number L2 read out in step S57 exceeds the stage reduction number L1 calculated in step S53, the motor output stage N1 is reset. After that, when the stage reduction number L2 read out in step S18 exceeds the stage reduction number L2 calculated in step S60 again, the motor output stage N1 is reset. That is, the motor output stage N1 is reset every time the pressing force P2 stronger than the pressing force P2 corresponding to the decremented number of stages is pressed, and if the pressing force P2 is small, the decremented number of stages up to that point is maintained. the motor output stage.

If it is determined in step S55 that the duration time T2 is 300 ms or more, the process proceeds to step S62 shown in FIG. 8 .

In step S62, the motor output stage obtained by subtracting one stage from the current motor output stage N1 is set as a new motor output stage N2. Then, it moves to step S63.

In step S63, it is determined whether or not the motor output stage N2 of which one stage has been subtracted in step S62 is 1 or more. That is, it is determined whether or not the motor 3 is driven. When the motor output stage N2 is 0, the process proceeds to step S5, and the state of the motor output 0 is maintained. If it is determined that the motor output stage N2 is 1 or more, the process proceeds to step S64.

In step S64, the continuation time T2 during which the second pressing operation part 12 is pressed is reset, and the measurement of the continuation time T2 is restarted. Then, it moves to step S65.

In step S65, the pressing force P2 of the second pressing operation part 12 is detected, and the process proceeds to step S66.

In step S66, the time interval TI corresponding to the pressing force P2 detected in step S25 is read out from the memory unit 26, and the process proceeds to step S67. In addition, the time interval TI corresponding to the pressing force P2 is the same as the time interval TI corresponding to the pressing force P1, for example, the time interval TI of five stages (10ms, 30ms, 50ms, 100ms, 300ms) is set corresponding to the pressing force P2.

In step S67, it is judged whether the duration T2 of the re-measurement started in step S64 exceeds the time interval TI read out in step S66. If it is determined that it exceeds, the process returns to step S62, and the current motor output stage N2 is set to a stage obtained by subtracting one stage. If it is determined that it is not exceeded, the process proceeds to step S68.

In step S68, it is determined whether or not the pressing of the second pressing operation unit 12 is continued. If it is determined that the pressing is not continued, the process proceeds to step S5, and the current motor output stage N2 is maintained. If it is determined that the pressing is continued, the process returns to step S65. Here, even if the pressing force P2 changes on the way, the process returns to step S65, the pressing force P2 of the second pressing operation part 12 is detected, and the time interval TI corresponding to the pressing force P2 is read out. Accordingly, after it is determined in step S55 that the duration T2 is 300 ms or more, the pressing force P2 can be adjusted by changing the speed of the motor output stage N2 by one stage at a time.

Next, with reference to FIG. 9, the reset process of the stage value of the motor output stage of the motor control part 22 is demonstrated. In addition, the motor control unit 22 stops the motor output when the fishing rig reaches the boat edge stop position in the above-described motor control process. In addition, the information on the stop position of the ship's edge is stored in the memory unit 26 in advance by a well-known method.

In step S71, it is determined whether or not the current motor output stage N0 is 1 or more. That is, it is determined whether or not the motor 3 is driven. If the motor 3 is not driven, the reset processing of the stage value of the motor output stage is not executed. If it is determined that the motor output stage N0 is 1 or more, the process proceeds to step S72.

In step S72, it is determined whether the fishing rig has reached the boat edge stop position. If it is not reached, the reset processing of the motor output stage value is not executed. If it is determined that the fishing rig has reached the edge stop position, the process proceeds to step S73.

In step S73, the motor output is stopped, that is, the drive of the motor 3 is stopped. Then, it moves to step S74.

In step S74, the motor output stage N0 is set to zero. That is, the stage value of the motor output stage is reset.

In the motor control process configured as above, the following effects can be obtained. The motor control unit 22 controls the motor control unit 22 when the durations T1 and T2 during which the first pressing operation unit 11 or the second pressing operation unit 12 is pressed are within a predetermined time range (in the present embodiment, the range is less than 100 ms). The motor output stage is increased by 1 stage, or decreased by 1 stage. That is, if the first pressing operation part 11 or the second pressing operation part 12 is pressed by the pressing forces P1 and P2 of 30 g or more, the motor output stage is increased or decreased by 1 regardless of the magnitude of the pressing forces P1 and P2. stage. For example, when the motor output stage is increased by two stages, the pressing operation within the predetermined time range is performed twice. Thereby, fine adjustment of the motor output stage can be made easy.

In addition, the motor control unit 22 increases the motor output stage corresponding to the pressing forces P1 and P2 in the first time range (in the present embodiment, the range of 100ms or more and less than 300ms) in which the durations T1 and T2 exceed the predetermined time range. , or decrease. Thereby, the motor output stage can be sharply increased or decreased.

Furthermore, the motor control unit 22 controls the time interval TI corresponding to the pressing forces P1 and P2 within the second time range (in the present embodiment, the range of 300 ms or more) exceeding the first time range for the duration T1 and T2 Increase the motor output stage by 1 stage, or decrease it by 1 stage. Thereby, the motor output stage can be further adjusted in a state in which the first pressing operation part 11 or the second pressing operation part 12 is continuously pressed.

And if the fishing rig reaches the stop position of the boat's edge, the stage value of the motor output stage is reset, so it is not necessary to deliberately set the motor output such as the conventional joystick type or dial type operating member to adjust the motor output. The operating member returns to the motor output stop position.

(h) In the foregoing embodiment, the rotational speed of the reel 2 is detected as the motor output for 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 wire winding diameter of the reel 2 may be calculated and controlled so that the tension becomes a predetermined value.

(i) In the foregoing embodiment, the control method when the motor 3 is rotated in response to the electrical signals output from the pressure sensors 11a and 12a can be controlled by a predetermined reel rotational speed, or by a predetermined torque value. 2 of the control, can also be selected arbitrarily.
