[0014] An electric reel 100 embodying the present invention is an electric reel that is motor-driven by power supplied from an external power source, as shown in FIG.

[0015] The electric reel 100 includes a reel body 1, a spool 2, a motor 3, a handle 4, a counter case 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 form part of a motor control device.

[0016] The reel body 1 has a frame 6, a first side cover 7 covering one side of the frame 6, a second side cover 8 covering the other side of the frame 6, and a front cover (not shown) covering the front of the frame 6. Inside the reel body 1, there are disposed a level wind mechanism (not shown) that operates in conjunction with the spool 2, and a rotation transmission mechanism (not shown) that transmits the rotation of the motor 3 and handle 4 to the spool 2, etc.

[0017] The spool 2 is disposed inside the reel body 1. The spool 2 is rotatably attached to the reel body 1 between a first side cover 7 and a second side cover 8.

[0018] The motor 3 is disposed inside the reel body 1. The motor 3 is PWM controlled by the motor control unit 17, and drives the spool 2 to rotate in the line winding direction in response to the pressing operation of the first pressing portion 11 and the second pressing portion 12.

[0019] The handle 4 is rotatably supported by the first side cover 7 .

[0020] The counter case 5 is disposed on the upper part of the reel body 1. The counter case 5 is fixed to a frame 6. The counter case 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 operating units 13 to 15. The first pressing unit 11 is an example of a pressing unit.

[0021] The first to third operation units 13-15 are mainly used when making various settings of the electric reel 100. The first to third operation units 13-15 are operated by pressing them. The first to third operation units 13-15 may be touch panels provided on the display unit 10. A control unit 16 (see FIG. 2) that performs various controls is housed inside the counter case 5.

[0022] The first pressing portion 11 and the second pressing portion 12 are provided on the reel body 1 to be operated by pressing. The first pressing portion 11 and the second pressing portion 12 are seesaw-type pressure-sensitive switches. 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 the first pressing force) that presses the first pressing portion 11 as an electric signal to the motor control portion 17. The second pressing portion 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) that presses the second pressing portion 12 as an electric signal to the motor control portion 17.

[0023] 2, the control unit 16 has, as its functional components, a motor control unit 17 that controls the motor 3, an increase rate setting unit 18, an upper limit setting unit 19, and a display control unit 20 that controls the display unit 10. The motor control unit 17 controls the output of the motor 3 (hereinafter referred to as motor output) in response to a pressing operation on the first pressing unit 11 or a pressing operation on the second pressing unit 12 via a motor drive circuit 21 that drives the motor 3 with PWM.

[0024] The control unit 16 is connected to the first pressing unit 11, the second pressing unit 12, and the first to third operation units 13 to 15. The control unit 16 is also connected to the display unit 10, a spool sensor 22 for detecting the rotation speed and rotation direction of the spool 2, and a memory unit 23. The memory unit 23 is, for example, a non-volatile memory, and stores various setting information for the electric reel 100, such as shelf position information and ship side stop position information.

[0025] The motor control unit 17 controls the motor output in stages from a stopped state to a maximum output. The motor control unit 17 controls the motor 3 by a PWM method, and the maximum output is a duty ratio of 100%. The motor output is, for example, the rotation speed of the motor 3. Note that, here, when a load is applied and the rotation speed of the spool 2 drops, feedback control is performed to maintain a predetermined rotation speed.

[0026] In this embodiment, the motor output is adjusted in 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. The motor output is adjusted in, for example, 31 stages.

[0027] The motor control unit 17 is configured to control the motor output in one of a plurality of control modes including at least the first control mode. The motor control unit 17 is configured to control the motor output in a control mode selected from the plurality of control modes. The motor control unit 17 switches the control mode in response to, for example, a pressing operation of the third operation unit 15.

[0028] The multiple control modes include a normal control mode. In the normal control mode, the motor control unit 17 increases the motor output (e.g., the rotation speed of the motor 3) in response to the first pressing force and decreases the motor output (e.g., the rotation speed of the motor 3) in response to the second pressing force. In the normal control mode, the motor control unit 17 maintains the motor output when the pressing operation on the first pressing unit 11 or the pressing operation on the second pressing unit 12 is released.

[0029] The lower and upper limits of the pressure output from the pressure sensors 11a and 12a are set (for example, lower limit 30 grams, upper limit 2 kilograms). The range between the lower and upper limits is divided into arbitrary steps (for example, 31 equal parts), and the number of step increases and steps decreases of the motor output corresponding to each step is set.

[0030] In the first control mode, motor control unit 17 controls the motor output in response to the first pressing force only while the pressing operation on first pressing unit 11 is continued. In the first control mode, motor control unit 17 reduces the motor output to 0 stage in response to the pressing operation on first pressing unit 11 being released.

[0031] In the first control mode, the motor control unit 17 increases the motor output in proportion to the magnitude of the first pressing force. In the first control mode, the range between the lower limit value and the upper limit value of the first pressing force output from the pressure sensor 11a is divided into arbitrary stages (for example, into 31 equal parts), and the motor output (here, the rotation speed of the motor 3) corresponding to each stage is set.

[0032] As shown in Fig. 3, when the first pressing unit 11 is pressed in the first control mode, the motor control unit 17 increases the motor output to a motor output stage N1 corresponding to the magnitude of the first pressing force in the first control mode. At this time, the motor control unit 17 increases the motor output by an increase rate set by the increase rate setting unit 18. The increase rate here is, for example, the acceleration (angular acceleration) when the rotation speed of the motor 3 reaches a rotation speed corresponding to the motor output stage N1 from a state in which the rotation of the motor 3 is stopped. In Fig. 3, the horizontal axis indicates time, and the vertical axis indicates the motor output stage N.

[0033] The increase degree setting unit 18 changes the increase degree of the motor output until the motor output corresponding to the first pressing force in the first control mode is reached, in response to the operation of the first operating unit 13. Here, the increase degree setting unit 18 changes the acceleration of the motor 3 until the rotation speed of the motor 3 corresponding to the motor output stage N1 in the first control mode, in response to the operation of the first operating unit 13.

[0034] 3, the acceleration setting value that can be set by the increase degree setting unit 18 is, for example, three levels of high acceleration H, medium acceleration M, and low acceleration L. The duty ratio corresponding to the high acceleration H is higher than the duty ratio corresponding to the medium acceleration M. The duty ratio corresponding to the medium acceleration M is higher than the duty ratio corresponding to the low acceleration L.

[0035] The set value of the acceleration is stored in the storage unit 23. When the first control mode is selected, the increase rate setting unit 18 changes the acceleration until the rotation speed of the motor 3 corresponding to the motor output stage N1 in the first control mode is reached in response to a pressing operation on the first operating unit 13.

[0036] Fig. 4 is a plan view of the display unit 10 in a state where the first control mode is selected. In a state where the first control mode is selected, the display control unit 20 causes the display unit 10 to display the acceleration setting value set by the increase rate setting unit 18. As shown in Fig. 4, when high acceleration H is selected, the display control unit 20 causes the display unit 10 to display [H].

[0037] The upper limit setting unit 19 changes the upper limit value of the motor output in the first control mode. That is, as shown in FIG. 5, the motor control unit 17 limits the maximum value of the motor output to the value set by the upper limit setting unit 19 in the first control mode. Here, the motor control unit 17 limits the stage of the motor output to the upper limit stage NM set by the upper limit setting unit 19. Specifically, in the first control mode, when the first operating unit 13 is pressed with a pressing force greater than the first pressing force corresponding to the upper limit stage NM, the motor output is limited to the upper limit stage NM. In FIG. 5, the horizontal axis indicates the first pressing force.

[0038] The control unit 16 switches to a setting mode of the upper limit setting unit 19 in response to, for example, a pressing operation of the third operation unit 15. At this time, the display control unit 20 causes the display unit 10 to display the setting mode of the upper limit stage NM. Then, for example, the first operation unit 13 or the second operation unit 14 is pressed to select the upper limit stage NM at any stage, and the upper limit stage NM is changed by operating the third operation unit 15 again.

[0039] When the first control mode is selected, the display control unit 20 causes the upper limit value set by the upper limit setting unit 19 to be displayed on the display unit 10. Note that FIG. 4 shows a state in which the value of the upper limit stage NM corresponding to the upper limit value is set to 22.

[0040] As shown in FIG. 6, in the first control mode, if the first pressing unit 11 is not pressed, the motor control unit 17 increases the motor output up to the upper limit value (here, the upper limit stage NM) set by the upper limit setting unit 19 in response to the operation of the second operating unit 14, and maintains the motor output at the upper limit value set by the upper limit setting unit 19. The motor control unit 17 stops the motor output when the fishing line reeled out from the spool 2 reaches the stop line length. The stop line length is set, for example, to a position where the tackle attached to the fishing line is easy to grab. For example, the motor control unit 17 sets the line length when the third operating unit 15 is pressed and held as the stop line length.

[0041] In the first control mode, when the motor control unit 17 is in a state where the motor output is maintained at the upper limit value (here, the upper limit stage NM) in response to the second operating unit 14 being operated, the motor control unit 17 stops the motor output in response to the second operating unit 14 being operated again.

[0042] In this motor control device for an electric reel, in the first control mode, the degree of increase in motor output until it reaches the motor output corresponding to the first pressing force in the first control mode can be changed in response to the operation of the first operating unit 13, thereby improving the operability of the jigging action performed by pressing the first pressing unit 11.

[0043] When the first control mode is selected, by operating the first operating unit 13, the rate of increase in motor output until the motor output corresponding to the first pressing force is reached can be quickly changed, further improving the operability of the jiggle action.

[0044] Since the motor control device is equipped with the upper limit setting unit 19, in the first control mode, it is possible to prevent the motor output from increasing more than the angler expects during a baiting action by pressing the first pressing unit 11.

[0045] In the first control mode, it becomes possible to automatically wind in the fishing line at the motor output corresponding to the upper limit stage NM set by the upper limit setting unit 19, thereby improving the operability of the electric reel in the first control mode.

[0046] <Other embodiments> Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the invention.

[0047] The functions of the first pressing portion 11 and the second pressing portion 12 may be switched depending on the operation of the first to third operating portions 13 to 15.

[0048] The pressure sensors 11a and 12a may not be individual components such as pressure-sensitive elements, but may be ones that generate an output in response to a minute amount of displacement of a member pressed by a spring with a large spring constant.

[0049] In the above embodiment, the rotation speed of the spool 2 is detected as the motor output and feedback controlled, but the current value supplied to the motor 3 may be controlled so that the winding torque becomes a predetermined value. Alternatively, the line winding diameter on the spool 2 may be calculated and the tension may be controlled to a predetermined value.

[0050] In the above embodiment, the control method for rotating the motor 3 in response to the electrical signals output from the pressure sensors 11a, 12a may be selectable from two methods: control at a predetermined spool rotation speed, or control at a predetermined torque value.

[0051] In the above embodiment, when the range between 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 number of stages, the range does not have to be divided equally. The range of pressing force corresponding to the stage with the low step increment and step decrement of the output stage of the motor 3 may be made larger than the range of the high step.

[0052] A program for realizing the motor control processing of the motor control unit 17 described above may be recorded on a computer-readable recording medium, and the motor control processing may be performed by, for example, a CPU (Central Processing Unit) executing the program recorded on the recording medium.
