Description

  The present invention relates to a motor control device, and more particularly, to a motor control device for an electric reel that is driven by a motor that operates with electric power supplied from a power source.

  Electric reels are often used for boat fishing and are useful for lifting fishing objects that live in relatively deep water. Recently, it is often used for fishing objects in relatively shallow places. As this type of electric reel, there is known an electric reel capable of rotating a spool in a winding direction by a motor and rotating the motor in a plurality of stages of rotation (see Patent Document 1). Conventional electric reels employ PWM control that controls the rotational state of the motor, such as the rotational speed and rotational torque, based on the duty ratio. A conventional electric reel adopting such PWM control has an operation unit (an example of a rotation state operation means) for setting, for example, a rotation speed of a motor (spool) in a plurality of stages from a low speed to a high speed, and according to an operation of the operation part. A control unit (an example of a motor control unit) that sets the basic duty ratio and increases or decreases the basic duty ratio so that the detection result of the rotational speed becomes the set speed.

On the other hand, the electric reel uses an external power source such as a storage battery to drive the motor. Conventionally, many lead batteries are used as storage batteries. However, recently, many storage batteries other than lead batteries such as lithium batteries have been used to increase the spool winding speed.
Japanese Patent No. 3448439

  Generally, in a lithium battery, the power supply voltage is set higher than that of a lead battery. For this reason, high-speed winding becomes possible compared with a lead battery. However, when such a high-voltage external power supply is used, the PWM control using the duty ratio has a problem that the rotational speed is higher than that when a lead battery is used even if the setting stage by the operation unit is the same.

  An object of the present invention is to provide a motor control device for an electric reel that can be set to a plurality of stages of rotation state, and can maintain the rotation state of each setting stage of the motor as constant as possible even when the power supply voltage of an external power source increases. There is in doing so.

  A motor control device for an electric reel according to a first aspect of the present invention is a dual-bearing reel control device that drives a spool rotatably mounted on a reel body by a motor, and includes a power supply voltage detection means, a rotation state operation means, a motor The power supply voltage detection means provided with the drive means and the motor control means is means for detecting the power supply voltage supplied to the motor. The rotation state operation means is a means for setting and operating the rotation state of the motor in N (N: integer greater than or equal to 2) stages. The motor driving means is means for driving the motor with electric power subjected to pulse width modulation. The motor control means controls the motor driving means on the basis of the first duty ratio according to the rotational state in which the setting operation has been performed, and when the detected power supply voltage exceeds the first voltage, the motor control means converts the first duty ratio to the power supply voltage. It is a means to correct according to.

  In this motor control device, when the power supply voltage exceeds the first voltage, the first duty ratio corresponding to the rotation state in which the motor driving means is set and operated is corrected according to the detected power supply voltage. For example, the first duty ratio is corrected by the ratio between the detected power supply voltage and the first voltage. Then, when the rotation state of the motor is set by the rotation state operation means, the motor drive means is controlled based on the first duty ratio or the corrected first duty ratio accordingly. Here, when the power supply voltage exceeds the first voltage, the first duty ratio is corrected according to the detected power supply voltage. For this reason, the first duty ratio becomes a smaller value than before the correction, and the rotational state of each setting stage of the motor can be maintained as constant as possible even when the power supply voltage rises above the first voltage.

  An electric reel motor control apparatus according to a second aspect of the present invention is the apparatus according to the first aspect, wherein the motor control means compares the first voltage with the power supply voltage detected immediately after the power is turned on. In this case, it is possible to quickly recognize that a different type of power source is connected by comparison with the power source voltage detected immediately after the power source is turned on.

  The motor control device for an electric reel according to a third aspect is the device according to the first or second aspect, wherein the motor control means multiplies the first duty ratio by a value obtained by dividing the first voltage by the detected power supply voltage. The first duty ratio is corrected. In this case, the first duty ratio can be easily corrected by a simple calculation.

  A motor control device for an electric reel according to a fourth aspect of the present invention is the device according to any one of the first to third aspects, further comprising a rotational speed detecting means for detecting a rotational speed of the spool, wherein the motor control means includes a motor driving means, Among the N rotation states, in the first rotation state up to the first M (M: integer less than or equal to N / 2), the speed detected by the rotation speed detecting means is increased stepwise for each M step. In the second rotation state from the (M + 1) stage to the N stage, the torque is controlled so that the tension acting on the fishing line wound around the spool increases stepwise. In this case, at a stage where the torque is relatively small, the motor can be prevented from stopping regardless of the load fluctuation by performing the constant speed control so that the speed does not fluctuate due to the load.

  The motor control device for an electric reel according to a fifth aspect of the present invention is the device according to any one of the first to fourth aspects, wherein the first duty ratio corresponding to the maximum stage set by the rotation state setting means is 85% or less. In this case, since the first duty ratio is 85% or less even at the maximum stage, it is possible to prevent troubles caused by the motor temperature rise.

  The motor control device for an electric reel according to a sixth aspect of the invention is the device according to any one of the first to fifth aspects, wherein the rotation state operating means is a lever member swingably attached to the reel body, and a swing of the lever member. The motor control unit performs speed control and torque control by dividing the detection result of the swing position detection unit into N stages. In this case, since the first duty ratio can be set by the swinging lever member, the stage and the accompanying first duty ratio can be set finely.

  The motor control device for an electric reel according to a seventh aspect is the device according to any one of the first to sixth aspects, wherein the electric reel is disposed between the spool and a handle for rotating the spool, And a clutch return mechanism for returning the clutch mechanism from the disconnected state to the connected state by reverse rotation of the motor, the motor control means corrects the first duty ratio during normal rotation of the motor, and During the reverse rotation of the motor, the motor drive means is controlled by gradually increasing the duty ratio from the second duty ratio to a second duty ratio larger than the second duty ratio and operable by the clutch return mechanism. In this case, since the clutch mechanism can be restored by utilizing the reverse rotation of the motor, an actuator dedicated for clutch restoration is not required. Further, since the voltage can be increased by gradually increasing the duty ratio from the second to the third duty ratio at the time of reverse rotation of the motor, shocking torque is less likely to act on components connected to the motor at the start of reverse rotation.

  An electric reel motor control device according to an eighth aspect of the invention is the device according to the seventh aspect, wherein the motor control means sets the second and third duty ratios to the power supply when the detected power supply voltage exceeds the first voltage. Correct according to the voltage. In this case, even if the power supply voltage increases, it is possible to suppress an increase in voltage that acts on the motor during reverse rotation of the motor.

  The motor control device for an electric reel according to a ninth aspect is the device according to the eighth aspect, wherein the motor control means multiplies the second and third duty ratios by a value obtained by dividing the first voltage by the detected power supply voltage. Then, the second and third duty ratios are corrected. In this case, the correction of the second and third duty ratios can be easily performed with a simple calculation.

After the notification, the driving of the motor is prohibited until the power supply voltage becomes equal to or lower than the second voltage. In this case, damage to the motor control unit and the motor due to overvoltage during use can be prevented. In addition, since motor driving is not prohibited during motor rotation, when power from the same power source is supplied to a plurality of electric reels, the motor is stopped due to an increase in inrush voltage generated by the operation of other electric reels. Can be prevented.

  An electric reel motor control apparatus according to an eleventh aspect of the present invention is the apparatus according to the tenth aspect of the present invention, wherein when the detection result of the power supply voltage detecting means is equal to or lower than a third voltage lower than the second voltage and the state continues for a predetermined time or longer, Second notification means for notifying that the voltage has dropped is further provided. In this case, it is possible to prevent problems caused by a decrease in power supply voltage.

  According to the present invention, when the power supply voltage exceeds the first voltage, the first duty ratio is corrected according to the detected power supply voltage. For this reason, the first duty ratio becomes a smaller value than before the correction, and the rotational state of each setting stage of the motor can be maintained as constant as possible even when the power supply voltage rises above the first voltage.

[Overall configuration of electric reel]
The electric reel 1 is fixed to a fishing rod R mounted on a boat FB of a fishing boat, for example, by a rod receiver RK. As shown in FIG. 2, the electric reel 1 includes a reel body 2 that is mainly mounted with a handle 2 a, a spool 3 that is rotatably mounted on the reel body 2, and a motor 4 that is mounted in the spool 3. I have. A counter 5 having a water depth display unit 98 is mounted on the top of the reel body 2. Further, an adjustment lever 101 for variably rotating the spool 3 is oscillated on the front side portion of the reel body 2, and a clutch operation lever 50 for turning on and off a clutch mechanism 7 (described later) is oscillated on the rear side portion. It is installed freely.

  The adjustment lever 101 is swingably mounted in a range of approximately 140 degrees, and a potentiometer 104 (FIG. 3) for detecting a swing angle is provided on a swing shaft (not shown) of the swing lever 101. It is connected. The potentiometer 104 can detect the rotation angle in the range of 0 to 270 degrees, and for example, detects the swing angle of the adjustment lever 101 in the range of 50 to 190 degrees. As shown in FIG. 3, the potentiometer 104 is connected to the reel control unit 100, and the motor 4 is controlled by the reel control unit 100 in accordance with the swing angle detected by the potentiometer 104. In this embodiment, the rotation of the motor 4 is stopped when the adjustment lever 101 is swung most rearward (near side).

  As shown in FIG. 3, the potentiometer 104 has a center shaft 111 connected to the swing shaft of the swinging adjustment lever 101 and a variable resistor 110 connected to the center shaft. The potentiometer 104 is provided with three terminals 151 a, 151 b, and 151 c that are connected to three locations of both ends of the variable resistor 110 and the central shaft 111. These three terminals 151a, 151b, and 151c are connected to the three terminals 153a, 153b, and 153c disposed on the first circuit board 150 provided in the counter 5 by lead wires 152a, 152b, and 152c, respectively. . For example, a power supply voltage of 5 volts is applied to the terminal 153a, and the terminal 153b is grounded. The terminal 153c is grounded via a pull-down resistor 154 and outputs a signal corresponding to the swing angle of the adjustment lever 101 to the reel control unit 100 described later. Here, based on the output signal, the reel control unit 100 can detect the swing angle of the adjustment lever 101 and can detect the presence or absence of disconnection of the three lead wires 152a, 152b, and 152c. That is, when the lead wires 152a and 152c are disconnected, the lever angle signal becomes 0 volts. Also, assuming that the value of the resistor 154 is 1 MΩ and the maximum value of the variable resistor 110 is 5 kΩ, the combined resistance (1 MΩ / (1 MΩ + 5 kΩ)) is approximately 1 when the lead wire 152 b is disconnected, so the output signal is 5 Become a bolt. On the other hand, when the lead wire 152b is not disconnected, the potentiometer 104 swings only in the range of 50 degrees to 170 degrees, and therefore, only a signal having a voltage lower than 5 volts is output. Therefore, if these values are output during operation, it is possible to determine the disconnection of the lead wires 152a, 152b, 152c.

  As shown in FIG. 4, the reel body 2 has a rotation transmission mechanism 6 that transmits the rotation of the handle 2 a to the spool 3 and transmits the rotation of the motor 4 to the spool 3, and is provided in the middle of the rotation transmission mechanism 6.

Further, when the decision button DB is pressed and held for 3 seconds or longer, for example, a zero set process in which the water depth data LX at that time is set as the reference position of the water depth 0 can be performed. Thereafter, the water depth data LX is displayed with the yarn length from the set reference position. In addition, the angler usually presses the enter button and sets it to 0 when the device reaches the sea surface. Further, a thread winding learning mode for learning the relationship between the spool rotation speed and the thread length can be entered by simultaneously pressing the shelf memo button TB and the fast winding button HB at a water depth of 6 m or less.

  Further, as shown in FIG. 14, a reel control unit 100 including a water depth display unit 98 and a microcomputer for controlling the motor 4 is provided inside the counter 5. The reel control unit 100 is connected to the operation key unit 99, a spool sensor 102 that detects the rotation speed and rotation direction of the spool 3 with, for example, two hall elements arranged in the rotation direction, and the electric reel 1. A power source voltage sensor 103 for detecting the voltage of the power source, a potentiometer 104 connected to an adjustment lever 101 for adjusting the speed of the spool 3 and the tension of the fishing line, and an information communication unit for exchanging information with the fish finder monitor 120 105 is connected.

  Further, the reel control unit 100 performs pulse width modulation (PWM) on various notification buzzers 106, a water depth display unit 98 for displaying water depth information, a storage unit 107 for storing various data, and the motor 4. A motor drive circuit 108 driven at a duty ratio is connected to another input / output unit. As shown in FIG. 8, the counter 5 accommodates a first circuit board 150 and a second circuit board 155 arranged below the first circuit board 150 with a space therebetween. Electrical components including a liquid crystal driving circuit for driving a liquid crystal display constituting the water depth display unit 98 are mounted on the first circuit board 150. Electronic components including a CPU constituting the reel control unit 100 and an EEPROM constituting the storage unit 107 are mounted on the rear surface. On the second circuit board 155, electrical components including two FETs constituting the motor driving circuit 108, the buzzer 106, two Hall elements constituting the spool sensor 102, and the like are mounted. The first circuit board 150 and the second circuit board 155 are electrically connected by an interconnector 156 that is mounted on a resin case and sandwiched between the boards 150 and 155.

  The water depth display unit 98 uses a segment-type liquid crystal display including a 7-segment numerical display. As shown in FIG. 13, the water depth, the shelf position, the bottom position, and various modes (shelf stop) are provided. The characters indicating the mode, bottom display mode, thread feed mode, and saddle mode) are displayed. Among these characters, the character “Sosai” is turned on when the electric reel 1 and the fish finder monitor 120 are connected by the power cord 130 and are communicable. Thereby, it can be confirmed instantaneously that the electric reel 1 fish finder monitor 120 can communicate. Further, a water depth display portion 98a for displaying the water depth of the device is provided in the central portion, and a set display portion 98b for displaying the set stage ST, the shelf position and the like, and a power supply figure indicating a decrease in power supply voltage are provided in the lower portion. 98c is provided.

  The reel control unit 100 controls the motor 4 in 31 stages including, for example, turning off the motor 4 in accordance with the output of the potentiometer 104 (that is, the swing angle of the adjustment lever 101). Specifically, the range of 140 degrees from 50 degrees to 190 degrees of the potentiometer 104 is divided into 31 appropriate stages, and it is determined which of the 31 stages ST is based on the output. In addition, among the 31 stages, the motor 4 is turned off at the stage (ST = 0) arranged on the frontmost side where no operation is performed. In the next four stages (ST = 1 to 4), for example, feedback speed control is performed to control the first duty ratio D1 with reference to the output of the spool sensor 102 so that the rotational speed of the spool 3 increases stepwise. . In the remaining 26 stages (ST = 5 to 30), the motor 4 is controlled with the first duty ratio D1 that increases at each stage ST and is corrected according to the bobbin diameter. As a result, the spool 3 does not stop rotating even if a high load is applied by controlling the speed in the first four stages where the speed is low. In the remaining 26 stages thereafter, control is performed with a constant first duty ratio D1 corrected by the bobbin diameter at each stage, so that the tension acting on the spool 3 becomes substantially constant, and Harris breakage is less likely to occur. . In the operation of the adjustment lever 101, the first duty ratio D1 does not exceed 85% even at the maximum stage. Further, when the fast winding button HB is operated, the motor 4 is driven at a high speed with the first duty ratio D1 of 95% at the maximum, for example. Thereby, the malfunction by the overheating of the motor 4 can be prevented beforehand.

  Further, the reel control unit 100 calculates the water depth of the device attached to the tip of the fishing line based on the output of the spool sensor 102, and displays it on the water depth display portion 98a. Furthermore, when the bottom position and the shelf position are set by operating the operation key unit 99, the calculated depth of water coincides with the set bottom position and the shelf position, and the device reaches the shelf position or the bottom position. Then, the motor 4 is reversely rotated to operate the clutch switching mechanism 8 via the first clutch return mechanism 12 to return the clutch mechanism 7 to the clutch-on state. Thereby, the device is arranged at that position.

  The storage unit 107 stores a plurality of map data for conversion into count values for each predetermined pulse of the spool sensor 102 and device depth data LX for various fishing lines. The plurality of marp data takes into consideration that the count value and the water depth data LX change according to the yarn diameter and the bobbin diameter. Map data is stored in advance in the storage unit 107 for a plurality of fishing lines often used in the electric reel 1 of that size. For fishing lines that are not stored in advance, map data is created by learning and stored in the storage unit 107.

  When the count value of the spool sensor 102 is output, the reel control unit 100 displays a value for display based on map data of a fishing line selected from a plurality of map data stored in the storage unit 107 based on the count value. The device water depth data LX is calculated, and the calculated water depth data LX is displayed on the water depth display unit 98. In addition, when the fish school monitor 120 is connected, various information including the water depth data LX for the device is output to the fish school monitor 120 via the information communication unit 105 and the communication line of the power cord 130.

  In the clutch return operation by the reverse rotation of the motor 4, as shown in FIG. 21, the reel control unit 100 gradually increases the duty ratio provided by the motor drive circuit 108 from the second duty ratio D2 to the third duty ratio D3. To go. As a result, the voltage applied to the motor 4 gradually increases from the first voltage V1 to the second voltage V2. Here, the first voltage V1 is preferably in the range of 2 to less than 6 volts, for example. The second voltage V2 is a voltage at which a later-described pressing member 91 can press the advance / retreat member 96 by the reverse rotation of the motor 4, and is preferably in the range of 6 volts to 12 volts. The second duty ratio D2 needs to be changed according to the power supply voltage PV. However, when the power supply voltage PV is 12 volts as in the case of using a lead battery, a range of 15% to less than 50% is preferable. The third duty ratio D3 is preferably in the range of 50% to 100%. As a result, the mechanism mounting shaft 75 that is fixed to the output shaft 30 during the reverse rotation of the motor 4 is less likely to idle.

  When the power supply voltage PV becomes 15 volts using a lithium battery, the duty ratios D1, D2, and D3 are corrected to a value of 12/15, for example, so as to correct the increase in the power supply voltage PV. As a result, even if a storage battery having a higher power supply voltage than a lead battery such as a lithium battery or a nickel metal hydride battery is used, the voltage applied when the motor 4 is rotated forward by the operation of the adjustment lever 101 and applied to the motor 4 at the start of reverse rotation. The first and second voltages V <b> 1 and V <b> 2 are less likely to fluctuate, and fluctuations in speed and torque during forward rotation of the motor 4 due to operation of the adjustment lever 101 are reduced, and are fixed to the output shaft 30 during reverse rotation of the motor 4. The mechanism mounting shaft 75 is more difficult to idle.

[Configuration of rotation transmission mechanism]
As shown in FIG. 4, the rotation transmission mechanism 6 includes a handle shaft 33 on which the handle 2 a is non-rotatably mounted, a main gear 34 that is rotatably mounted on the handle shaft 33, and a pinion gear 35 that meshes with the main gear 34. And a drag mechanism 36 disposed around the handle shaft 33 and a planetary gear mechanism 40 that decelerates the rotation of the motor 4 in two stages.

  The handle shaft 33 is rotatably supported on the fixed frame 20 by a bearing 37 and a roller clutch 38 that prohibits rotation of the handle shaft 33 in the thread drawing direction. The handle 2a is non-rotatably attached to the tip of the handle shaft 33, and the star drag 39 of the drag mechanism 36 is screwed inside.

  The rotation of the handle shaft 33 is transmitted to the main gear 34 via the drag mechanism 36. The pinion gear 35 is attached to a pinion gear shaft 47 erected on the side cover 15 so as to be rotatable and axially movable. The pinion gear shaft 47 is disposed concentrically with the output shaft 30 of the motor 4. An engagement recess 35 a is formed at the left end of the pinion gear 35 in FIG. 2, and a tooth portion 35 b that meshes with the main gear 34 is formed at the right end. A small-diameter constricted portion 35c is formed between them. The engagement recess 35a engages with an engagement protrusion 46a formed at the tip (right end in FIG. 2) of the planetary gear mechanism 40, which will be described later, in a non-rotatable manner. The clutch mechanism 7 is composed of the engagement concave portion 35a and the engagement convex portion 46a. The pinion gear 35 is moved in the axial direction of the pinion gear shaft 47 by the clutch switching mechanism 8 engaged with the constricted portion 35c.

  The drag mechanism 36 brakes the rotation of the spool 3 in the yarn unwinding direction. The drag mechanism 36 includes a star drag 39 and a drag disk 48 in which a pressing force (drag force) on the main gear 34 is changed by the star drag 39. Mechanism.

Three first planetary gears 43 arranged, a first carrier 45 rotatably supporting the first planetary gear 43, a second sun gear 42 fixed to the first carrier 45, and a second sun gear 42 For example, it includes three second planetary gears 44 that are arranged at regular intervals on the circumference, for example, and a second carrier 46 that rotatably supports the second planetary gear 44. The first planetary gear 43 and the second planetary gear 44 mesh with an internal gear 3 d formed on the inner peripheral surface of the spool 3. The first carrier 45 and the second carrier 46 are cylindrical shafts, through which the output shaft 30 of the motor 4 passes. The second sun gear 42 and the second carrier 46 are provided to be rotatable relative to the output shaft 30. The second carrier 46 is rotatably mounted on the gear plate 3c. Between the second planetary gear 44 and the first carrier 45, a washer member 29 made of synthetic resin having a slippery property is mounted. When such a washer member 29 is mounted, the play of the first carrier 45 is reduced, and the noise of the planetary gear mechanism 40 can be reduced.

[Configuration of clutch mechanism]
The clutch mechanism 7 is a mechanism capable of switching the spool 3 between a yarn winding-capable state and a free-rotatable state. As shown in FIG. 4, the clutch mechanism 7 includes the engagement concave portion 35 a of the pinion gear 35 and the engagement convex portion 46 a of the second carrier 46 as described above. The state in which the pinion gear 35 moves to the left and engages with the engagement recess 35a and the engagement protrusion 46a of the second carrier 46 is the clutch-on state, and the separated state is the clutch-off state. In the clutch-on state, the spool 3 is in a yarn winding-capable state, and in the clutch-on state, the spool 3 is in a freely rotatable state. If the motor 4 is turned in the yarn winding direction in the clutch-off state, the frictional resistance of the planetary gear mechanism 40 is reduced. As a result, the free rotation speed of the spool 3 increases, and the device can be quickly lowered to the shelf position. This is the yarn feeding process.

[Configuration of clutch switching mechanism]
The clutch switching mechanism 8 switches the on / off state of the clutch mechanism 7. As shown in FIGS. 6 and 7, the clutch switching mechanism 8 rotates around the pinion gear shaft 47 by the clutch operating lever 50 swingably attached to the side cover 15 and the swing of the clutch operating lever 50. The clutch cam 51 and the clutch yoke 52 that moves in the direction of the pinion gear shaft 47 by the rotation of the clutch cam 51 are provided.

The second projecting portion 56b extends forward of the reel, and extends outward of the ratchet wheel 62 of the first one-way clutch 9 disposed between the main gear 34 and the fixed frame 20. A first toggle spring 65 made of a torsion coil spring is engaged with the second protrusion 56b. The other end of the first toggle spring 65 is locked to the fixed frame 20. By the first toggle spring 65, the clutch cam 51 is held at the clutch-on position shown in FIG. 6 and the clutch-off position shown in FIG. A swing shaft 51a is mounted on the second protrusion 56b, and an engagement member 61 of the second clutch return mechanism 12 is swingably mounted on the swing shaft 51a.

The third protrusion 56c extends rearward and downward of the reel, and the first clutch return mechanism 11 is connected to the tip of the third protrusion 56c.

  The cam protrusions 57a and 57b are provided to press the clutch yoke 52 outward in the spool axial direction. That is, when the clutch cam 51 rotates from the clutch-on position shown in FIG. 6 to the clutch-off position shown in FIG. 7, the clutch yoke 52 rides on the cam protrusions 57a and 57b and moves outward in the spool axial direction (see FIG. 6 and FIG. 7). Move forward).

  The clutch yoke 52 is disposed on the outer peripheral side of the pinion gear shaft 47, and is supported by two guide shafts 53 so as to be movable in parallel with the axis of the pinion gear shaft 47. The clutch yoke 52 has a semicircular arc engaging portion 52a that engages with the constricted portion 35c of the pinion gear 35 at the center thereof. Further, a coil spring 54 is disposed in a compressed state between the clutch yoke 52 and the side cover 15 on the outer periphery of the guide shaft 53 that supports the clutch yoke 52, and the clutch yoke 52 is always inward ( The side plate 17 is biased.

  In such a configuration, in a normal state, the pinion gear 35 is located at the inner clutch engagement position, and the engagement concave portion 35a and the engagement convex portion 46a of the second carrier 46 are engaged with each other to provide a clutch mechanism. 7 is in a clutch-on state. On the other hand, when the pinion gear 35 is moved outward by the clutch yoke 52, the engagement concave portion 35a and the engagement convex portion 46a are disengaged, and the clutch is turned off.

[Configuration of the first one-way clutch]
The first one-way clutch 9 is provided to prevent the handle 2a from rotating when the motor 4 is driven, by prohibiting the handle shaft 33 from rotating in the yarn drawing direction. The first one-way clutch 9 includes a ratchet wheel 62 that is non-rotatably attached to the handle shaft 33, a ratchet wheel 62, a ratchet pawl 71, and a clamping member 72.

  The ratchet wheel 62 is non-rotatably mounted on the handle shaft 33 between the main gear 34 and the fixed frame 20. On the outer peripheral side of the ratchet wheel 62, serrated ratchet teeth 62a are formed.

  The ratchet pawl 71 is rotatably mounted on the side plate 17. The clamping member 72 is attached to the tip of the ratchet pawl 71 and can clamp the outer peripheral surface of the ratchet wheel 62. Due to the friction between the pinching member 72 and the ratchet wheel 62, the ratchet pawl 71 is separated to a position where it does not interfere with the ratchet teeth 62a when the ratchet wheel 62 rotates clockwise (yarn winding direction). The ratchet pawl 71 does not come into contact with each other at the time of rotation, and the noise can be reduced. On the other hand, when rotating counterclockwise (yarn feeding direction), the ratchet pawl 71 is pulled to a position where it interferes with the ratchet teeth 62a, and rotation in the yarn drawing direction is prohibited. In this electric reel, in addition to the first one-way clutch 9, a roller clutch 38 that instantaneously inhibits the reverse rotation of the handle shaft 33 is disposed between the side cover 15 and the handle shaft 33.

[Configuration of the second one-way clutch]
The second one-way clutch 10 is provided to prevent the planetary gear mechanism 40 from operating due to the reverse rotation of the motor 4 when the handle 2a is operated. As shown in FIGS. 8 and 9, the second one-way clutch 10 has a claw wheel 81 that is non-rotatably mounted on the second shaft portion 75 b of the mechanism mounting shaft 75, and a swing that makes contact with and separates from the claw wheel 81. A claw 82; a torsion coil spring 83 that urges the swing claw 82 toward the claw wheel; and a claw control mechanism 84 that controls the swing claw 82 when the motor 4 rotates forward in the yarn winding direction. ing.

  The claw wheel 81 has an oval hole 81b that engages with a chamfered portion 75c formed in the second shaft portion 75b of the mechanism mounting shaft 75 in a non-rotatable manner at the center. Moreover, it has two protrusion parts 81a formed in the outer periphery so as to protrude in the radial direction.

  The swinging claw 82 has a base end mounted on a swinging shaft 80 erected on the bulging portion 27 of the side plate 16 so as to be swingable. At the tip of the swinging claw 82, a claw portion 82a that protrudes toward the back side in FIG. 9 is formed. The claw portion 82a contacts the projection 81a of the claw wheel 81 to prevent reverse rotation of the claw wheel 81 (output shaft 30), and contacts the silent cam 85 (to be described later) of the claw control mechanism 84 to dodge the projection 81a. It is provided to swing the swinging claw 82 to the position.

  The swinging pawl 82 swings between the reverse rotation prohibiting position where the first clutch return mechanism 11 can contact the protrusion 81a shown in FIG. 10 and the reverse rotation allowing position shown in FIG. As described above, when the motor 4 is rotating forward, it swings slightly toward the reverse rotation permission position to the position where the projection 81a of the ratchet wheel 81 is dodged.

  The claw control mechanism 84 is a mechanism for swinging the swing claw 82 to the reverse rotation permission position side to a position where the projection 81a of the claw wheel 81 is displaced when the motor 4 rotates forward. The claw control mechanism 84 is rotatably mounted on the first shaft portion 75a of the mechanism mounting shaft 75, and has a silent cam 85 having a protruding pressing portion 85a on the outer periphery for pressing the swinging claw 82 toward the reverse rotation prohibiting position. And a rotation restricting portion 86 for restricting the rotation range of the silent cam 85. The silent cam 85 is frictionally engaged with the first shaft portion 75 a and rotates in the same direction in conjunction with the rotation of the mechanism mounting shaft 75, and the rotation cam 86 rotates the silent cam 85. The mechanism mounting shaft 75 can rotate even if it is restricted. The rotation restricting portion 86 includes a locking piece 86a that is integrally formed so as to protrude in the radial direction from the silent cam 85, and a notch portion 86b that is formed on the cover member 28 and is locked with the locking piece 86a. Yes. The notch 86b is formed by cutting the arc-shaped side surface of the cover member 28 into an arc shape within the swing range. A washer 87 is mounted between the silent cam 85 and the claw wheel 81.

[Configuration of first clutch return mechanism]
The first clutch return mechanism 11 returns the clutch mechanism 7 from the clutch-off state to the clutch-on state via the clutch switching mechanism 8 by the reverse rotation of the motor 4. As shown in FIGS. 4 to 7, the first clutch return mechanism 11 includes a pressing mechanism 88 that is mounted on the mechanism mounting shaft 75 side by side with the ratchet wheel 81 and rotates in conjunction with at least the reverse rotation of the motor 4, and the clutch switching mechanism 8. And an interlocking mechanism 89 that operates in conjunction with the.

  The pressing mechanism 88 is arranged on the third shaft portion 75 d of the mechanism mounting shaft 75 side by side with the claw wheel 81, and rotates in conjunction with the reverse rotation of the motor 4. The pressing mechanism 88 includes a roller clutch 90 mounted on the third shaft portion 75d and a pressing member 91 mounted non-rotatably on the outer peripheral side of the roller clutch 90. The roller clutch 90 is an outer ring idle type one-way clutch having an outer ring 90a and a plurality of rollers 90b housed in the outer ring 90a. The inner ring is integrated with the third shaft portion 75d of the mechanism mounting shaft 75. The roller clutch 90 transmits only the reverse rotation of the motor 4 to the pressing member 91. Here, the roller clutch 90 is attached to the pressing member 91 when the interlocking mechanism 89 is close to the pressing member 91 and the motor 4 is rotated forward in the clutch-off state. This is to prevent a problem from occurring even if contact is made. When the motor 4 rotates in the reverse direction, the rotation of the pressing member 91 is transmitted via the roller clutch 90 and rotates. The pressing member 91 includes, for example, three cylindrical portions 91a that are non-rotatably mounted on the outer ring 90a of the roller clutch 90, and are formed on the outer peripheral side of the cylindrical portion 91a in the radial direction and spaced apart in the circumferential direction. And a protrusion 91b. The protrusion 91 a is a protrusion that can press the interlock mechanism 89.

  The interlocking mechanism 89 operates in conjunction with the operation of the clutch switching mechanism 8. When the clutch mechanism 7 is switched to the clutch-off state by the clutch switching mechanism 8, the interlocking mechanism 89 comes into contact with the swinging claw 82 and moves the swinging claw 82 to the claw wheel. It moves away from 81 and moves to a release position where pressing by the pressing mechanism 88 is possible. As a result, the motor 4 enters the reverse rotation permission state. Further, when the motor 4 rotates in the reverse state, the interlocking mechanism 89 is pressed by the pressing mechanism 88 and moves to a locking position where pressing is impossible. When moved to the locking position, the swinging claw 82 moves away from the swinging claw 82 and is locked to the claw wheel 81.

  The interlock mechanism 89 passes through the side plates 16 and 17, has one end rotatably mounted on the side plates 16 and 17, and a connection shaft 93 disposed outside the fixed frame 20, and cannot be rotated at both ends of the connection shaft 93. The first and second lever members 94 and 95 are attached, and the advance / retreat member 96 is connected to the tip of the second lever member 95.

The connecting shaft 93 is a shaft member that is rotatably attached to the side plates 16 and 17 and has one end protruding outward from the fixed frame 20 and the other end protruding outward from the side plate 16. Chamfered portions 93a and 93b that are parallel to each other for mounting the first and second lever members 94 and 95 in a non-rotatable manner are formed at the protruding ends of the connecting shaft 93. The first lever member 94 has a base end Is a member that is non-rotatably attached to the chamfered portion 93a of the connecting shaft 93 on the fixed frame 20 side. The distal end of the first lever member 94 is locked to the distal end of the third projecting portion 56c of the clutch cam 51 constituting the clutch switching mechanism 8 so as to be rotatable and movable for a predetermined distance. Thereby, the rotation of the clutch cam 51 is transmitted to the first clutch return mechanism 11, and the return operation of the first clutch return mechanism 11 is transmitted to the clutch cam 51 and the clutch switching mechanism 8 can be operated.

  The second lever member 95 is a member whose base end is non-rotatably attached to the chamfered portion 93 b of the connecting shaft 93 on the side plate 16 side. The distal end of the second lever member 95 is locked to the proximal end of the advance / retreat member 96 so as to be rotatable and movable for a predetermined distance. As a result, the advance / retreat member 96 advances and retracts in conjunction with the operation of the clutch switching mechanism 8, and the clutch changeover mechanism 8 operates in the clutch-off direction by the backward operation of the advance / retreat member 96.

  The advancing / retracting member 96 is guided by a pair of guide portions 27 a and 27 b formed on the bulging portion 27 so as to be linearly movable toward the swinging claw 82 and the pressing member 88. The advancing / retracting member 96 is a plate-like member in which the second lever member 95 is connected to the base end so as to be rotatable and movable within a predetermined range. The advancing / retracting member 96 is understood by the swinging claw 82 and extends so that it can contact the lower surface of the swinging claw 82, and a second contact member 96b bent from the base of the first contact portion 96a toward the pressing member 91. A contact portion 96b is provided at the tip. The advancing / retreating member 96 has a release position shown in FIG. 11 in which the second contact portion 96b can be pressed by the pressing member 91 and the first contact portion 96a presses the swinging claw 82 and swings to the reverse rotation permission position. The one contact portion 96a is movable away from the swinging claw 82 and to the locking position shown in FIG. 10 where the pressing by the pressing member 91 is impossible. Specifically, when the clutch switching mechanism 8 moves from the clutch-off position to the clutch-on position side, the first and second lever members 94 and 95 swing and the advance / retreat member 96 advances to the release position, and the motor 4 When it is pressed by the pressing member 91 by reverse rotation, it moves backward to the locking position. As a result, the clutch cam 51 rotates in the clutch-on direction via the second and first lever members 95, 94, the clutch operation lever 50 returns to the clutch-on position, and the clutch mechanism 7 enters the clutch-on state.

[Configuration of second clutch return mechanism]
The second clutch return mechanism 12 returns the clutch cam 51 disposed at the clutch-off position to the clutch-on position according to the rotation of the handle 2a in the yarn winding direction, and returns the clutch mechanism 7 to the clutch-on state. The cam 51 returns the clutch operation lever 50 from the clutch-off position to the clutch-on position. The second clutch return mechanism 12 urges the engaging member 61, the ratchet wheel 62 having ratchet teeth 62a formed on the outer periphery thereof, and the engaging member 61 to be moved toward the engaging position and the non-engaging position. And a second toggle spring 66. As described above, the engaging member 61 is swingably supported by the second projecting portion 56b of the clutch cam 51, and has a first protrusion 61a that engages with the ratchet teeth 62a of the ratchet wheel 62, and a first protrusion 61a. The first protrusion 61a has a second protrusion 61b extending to the left in FIG.

  The first protrusion 61a is bent toward the outside of the ratchet wheel 62, and the second protrusion 61b is bent to the opposite side to the fixed frame 20 side. The fixed frame 20 is formed with a deformed trapezoidal guide protrusion 20a that engages with the second protrusion 61b. The guide protrusion 20a is provided to control the swinging direction of the engaging member 61 by engaging with the second protrusion 61b.

  When the engaging member 61 is disposed at the engaging position, the first protrusion 61a is located on the inner peripheral side from the outer periphery of the ratchet wheel 62 and can be locked to the ratchet teeth 62a, and is disposed at the non-engaging position. Then, the first protrusion 61 a is located at a position slightly separated from the outer periphery of the ratchet wheel 62. The engaging member 61 is disposed in front of and above the axis of the ratchet wheel 62. For this reason, the space on the rear side of the ratchet wheel 62 can be small as compared with the conventional example disposed behind the ratchet wheel 62. The first protrusion 61a of the engaging member 61 is pulled by the ratchet teeth 62a and rotates from the engaging position shown in FIG. 7 to the non-engaging position shown in FIG.

  Since the level wind mechanism and the casting control mechanism have the same configuration as a conventionally known electric reel, description thereof is omitted.

[Clutch switching operation]
Next, the clutch switching operation of the electric reel will be described.

  In a normal state, the clutch yoke 52 is pushed inward in the pinion gear axial direction by the coil spring 54, whereby the pinion gear 35 is moved to the clutch-on position. In this state, the engagement concave portion 35a of the pinion gear 35 and the engagement convex portion 46a of the second carrier 46 are engaged with each other and the clutch is on.

  When putting the device, the clutch operating lever 50 is swung to the clutch-off position shown in FIG. When the clutch operation lever 50 swings from the clutch-on position shown in FIG. 6 to the clutch-off position shown in FIG. 7, the clutch cam 51 rotates counterclockwise in FIG. As a result, the clutch yoke 52 rides on the cam protrusions 57a and 57b of the clutch cam 51, and the clutch yoke 52 is moved outward in the pinion gear axial direction. Since the clutch yoke 52 is engaged with the constricted portion 35c of the pinion gear 35, the pinion gear 35 is also moved in the same direction as the clutch yoke 52 moves outward. In this state, the engagement concave portion 35a of the pinion gear 35 and the engagement convex portion 46a of the second carrier 46 are disengaged, and the clutch is turned off. In this clutch-off state, the spool 3 is in a freely rotatable state. As a result, the fishing line is unwound from the spool 3 due to the weight of the device.

  In the yarn feed mode, for example, when the feed amount exceeds a predetermined amount (for example, the water depth display of the device is 6 m) or the rotation speed of the spool 3 exceeds the predetermined speed, the motor 4 rotates in the yarn winding direction. Since the second carrier 46 rotates in this clutch-off state, the planetary gear mechanism 40 does not decelerate even when the motor 4 is rotated forward, but the friction between the planetary gear mechanism 40 and the spool 3 is reduced, and the spool 3 is free. Rotates in the yarn unwinding direction at a higher speed than the rotating state

  Further, when the clutch cam 51 rotates to the clutch-off position, the engaging member 61 of the second clutch return mechanism 12 is guided by the guide protrusion 20a and swings in the clockwise direction. The spring 66 biases the ratchet wheel 62 inward. As a result, the engaging member 61 is disposed at an engaging position where the engaging member 61 is locked to the ratchet teeth 62a.

  Further, when the clutch cam 51 rotates to the clutch-off position, the advance / retreat member 96 of the interlocking mechanism 89 of the first clutch return mechanism 11 advances from the locking position shown in FIG. 10 to the release position shown in FIG. When the advance / retreat member 96 advances to the release position, the first contact portion 96a comes into contact with the swing claw 82 of the second one-way clutch 10, and the swing claw 82 is moved from the reverse rotation prohibition position shown in FIG. 10 to the reverse rotation permission position shown in FIG. Rocks. As a result, the motor 4 becomes in a state capable of reverse rotation. When the advance / retreat member 96 advances to the release position, the second contact portion 96a is disposed at a position where the projection 91b of the pressing member 91 can be pressed.

  When the device is placed on a predetermined shelf, the motor 4 is rotated in the reverse direction, the handle 2a is rotated in the yarn winding direction, or the clutch operating lever 50 is swung to the clutch-on position to stop the thread feeding of the spool 3. . In the automatic shelf stop mode, the spool 3 is fed out by the reverse rotation of the motor 4 and dynamically stops at the shelf position.

  When the motor 4 is reversely rotated, the first clutch return mechanism 11 returns to the clutch-on state. When the motor 4 is reversely rotated, as shown in FIG. 11, the pressing member 91 is reversely rotated (clockwise rotation in FIG. 11), and any one of the three protrusions 91b presses the second contact portion 96b of the advance / retreat member 96. Then, the advance / retreat member 96 is retracted from the release position toward the locking position. Then, the clutch cam 51 connected to the first lever member 94 via the second lever member 95 and the connecting shaft 93 rotates clockwise in FIG. At this time, when the dead point of the first toggle spring 65 is exceeded, the clutch cam 51 returns to the clutch-on position, whereby the advance / retreat member 96 also returns to the locking position. When the clutch cam 51 rotates clockwise toward the clutch-on position, the clutch yoke 52 riding on the cam protrusions 57a and 57b of the clutch cam 51 descends from the cam protrusions 57a and 57b and the coil spring 54 is attached. It moves inward in the spool axial direction by the force. As a result, the pinion gear 35 also moves inward in the spool axial direction and is disposed at the clutch-on position. When the clutch cam 51 rotates clockwise in FIG. 7, the clutch operation lever 50 locked to the first protrusion 56a also swings to the clutch-on position. Thereby, the clutch mechanism 7 can be changed from the clutch-off state to the clutch-on state without operating the clutch operation lever 50. When the advancing / retracting member 96 is locked and returned to the position, the swinging claw 82 urged by the torsion coil spring 83 returns to the reverse rotation prohibiting position, and the first one-way clutch 9 enters the reverse rotation prohibiting state, and the motor Inversion of 4 is prohibited.

  During the reverse rotation of the motor 4, the pressing member 91 mounted on the mechanism mounting shaft 75 via the roller clutch 90 collides with the second contact portion 96 b of the advance / retreat member 96 and presses it. At this time, an impact acts on the pressing member 91, and the torque caused thereby acts on the serration 30 a of the fixed portion between the mechanism mounting shaft 75 and the output shaft 30. Since this portion has a small diameter, the force in the tangential direction is increased, and if the power supply voltage is applied to the motor 4 as it is, there is a possibility that the portion may idle. Therefore, in the present embodiment, the motor 4 is controlled at a duty ratio that gradually increases from the second duty ratio D2 to the third duty ratio D3 shown in FIG. The member 96 is gradually raised to a voltage that can be pressed. As a result, the torque when the pressing member 91 collides with the advancing / retracting member 96 at the start of reverse rotation is reduced, and the drive components mounted on the output shaft 30 such as the mechanism mounting shaft 75 mounted with the pressing member 91 are less likely to idle. .

  When the handle 2a is rotated in the yarn winding direction, the second clutch return mechanism 12 returns to the clutch-on state. When the handle 2a is rotated in the yarn winding direction, the handle shaft 33 rotates clockwise in FIG. Accordingly, the ratchet wheel 62 fixed to the handle shaft 33 so as not to rotate is also rotated clockwise. When the ratchet wheel 62 rotates clockwise, the first protrusion 61a of the engaging member is caught by the ratchet teeth 62a, and the engaging member 61 is pulled.

  When the engaging member 61 is pulled, the engaging member 61 is guided by the guide protrusion 20 a and swings counterclockwise. When the engaging member 61 exceeds the dead point of the second toggle spring 66, the engaging member 61 is moved to the ratchet wheel 62. Is energized outward. Then, the engaging member 61 swings outward toward the non-engaging position where the ratchet wheel 62 is not engaged.

  When the engaging member 61 is pulled, the clutch cam 51 connected to the engaging member 61 rotates clockwise in FIG. 7 and returns to the clutch-on position as described above. Thereby, also here, the clutch mechanism 7 can be changed from the clutch-off state to the clutch-on state without operating the clutch operation lever 50.

  The engagement member 61 of the second clutch return mechanism 12 is disposed on the upper front side of the handle shaft 33. The upper front position of the handle shaft 33 is an empty space when the counter 5 is provided. When the engaging member 61 is provided in this vacant space, the bulge of the reel main body can be reduced as compared with a configuration in which the engaging member is disposed behind and below the handle shaft as in the prior art.

  In the first and second clutch return mechanisms 11 and 12, even if the clutch operating lever 50 is operated from the clutch-off position to the clutch-on position, the advancing / retracting member 96 returns to the locking position and the engaging member 61 is not engaged. It goes without saying that it returns to the matching position.

  When a fish is put on the device in the clutch-on state, the spool 3 is rotated in the line winding direction by the rotational drive of the handle 2a or the motor 4, and the fishing line is wound up.

  During manual winding, the rotation of the handle 2a in the yarn winding direction (clockwise rotation in FIG. 6) is transmitted to the spool 3 at an increased speed via the handle shaft 33, the main gear 34, the pinion gear 35, and the planetary gear mechanism 40. Is done. At this time, the reverse rotation of the motor 4 (counterclockwise rotation when viewed from the right side of FIG. 4) is prohibited by the second one-way clutch 10. Therefore, the first sun gear 41 of the planetary gear mechanism 40 does not reverse, and the second planetary gear 44 and the first carrier rotate from the second carrier 46 that rotates in the yarn winding direction (clockwise rotation as viewed from the right side in FIG. 4). The rotation is transmitted to the internal gear 3d via the first planetary gear 43, and the spool 3 is driven to increase in the yarn winding direction.

  When the motor is driven, the rotation of the motor 4 that normally rotates (clockwise rotation as viewed from the right side in FIG. 3) is transmitted to the spool 3 via the planetary gear mechanism 40. At this time, the first one-way clutch 9 prohibits rotation of the handle shaft 33 in the yarn feeding direction (counterclockwise rotation when viewed from the right side of FIG. 4), and therefore the second carrier 46 is reversely rotated (viewed from the right side of FIG. 4). (Clockwise rotation) is prohibited. For this reason, the rotation of the decelerated second sun gear 42 is transmitted to the internal gear 3d via the second planetary gear 44, and the spool 3 is driven to decelerate.

  Also, as shown in FIG. 12, when the motor 4 rotates normally (counterclockwise rotation in FIG. 12) in the clutch-on state, the silent cam 85 of the pawl control mechanism 84 rotates in the same direction, and the rotation restricting portion 86. As a result, the claw portion 82a of the swinging claw 82 stops at the position where the pressing portion 85a presses. At this time, since the silent cam 85 is merely frictionally engaged with the mechanism mounting shaft 75, the motor 4 rotates as it is. As a result, the swinging claw 82 is pressed by the pressing portion 85a and swings to the reverse rotation permission position side to the position where the projection 81a of the claw wheel 81 is displaced, so that the claw wheel 81 does not contact the swinging claw 82. For this reason, when the motor 4 rotates in the forward direction, the click sound due to the swinging claw 82 of the first one-way clutch 9 repeatedly contacting the claw wheel 81 is not generated, and the noise can be reduced.

  When the motor 4 rotates in the reverse direction, the silent cam 85 also rotates in the same direction, and as shown in FIG. 10, the rotation restricting portion 86 stops at a position where the pressing portion 85a is disengaged from the claw portion 82a, and the swinging claw 82 is twisted. The coil spring 83 is biased to return to the reverse rotation prohibited position.

  Further, when the motor 4 rotates in the forward direction in the clutch-off state as in the yarn feed mode, the silent cam 85 can also rotate in the same direction to achieve noise reduction. At this time, since the pressing member 91 is mounted on the mechanism mounting shaft 75 via the roller clutch 90 that transmits only the reverse rotation of the motor 4, the rotation of the mechanism mounting shaft 75 is not transmitted to the pressing member 91. For this reason, even if the advancing / retracting member 96 is disposed so as to be in contact with the pressing member 91 in the clutch-off state, the pressing member 91 does not press the advancing / retreating member 96, and there is no problem due to this.

[Operation of reel control unit]
Next, specific control processing performed by the reel control unit 100 will be described with reference to the control flowchart of FIG.

  When an external power source is connected to the electric reel, initial setting is performed in step S1 of FIG. In this initial setting, the count value of the spool rotation number is reset, and various variables and flags are reset. In step S2, the power supply voltage PV detected by the power supply voltage sensor 103 is captured. In step S3, it is determined whether or not the power supply voltage PV is higher than Vh1 (for example, 12 volts), that is, whether or not a type of storage battery having a higher power supply voltage than the lead storage battery is connected to the reel. When a battery with a high power supply voltage PV (for example, a lithium battery or a nickel metal hydride battery) is connected, the process proceeds from step S3 to step S4, and the duty ratios D1, D2, and D3 at the time of motor reverse rotation are detected. Correction is performed according to the power supply voltage PV. Specifically, the basic first, second, and third duty ratios D1, D2, and D3 are multiplied by a value (Vh1 / PV) obtained by dividing Vh1 (for example, 12) by the power supply voltage PV. The second and third duty ratios D1, D2, and D3 are set. As a result, even if the power supply voltage PV fluctuates, the rotation state of the spool 3 is less likely to fluctuate even when duty control is performed during forward rotation (at the time of yarn winding), and is applied to the motor 4 during reverse rotation (at the time of clutch return). The first and second voltages V1 and V2 to be changed are less likely to fluctuate. In this embodiment, the power supply voltage for determining the power supply is determined only once after the initial setting for connecting the power supply. However, the determination may be performed a plurality of times after the power supply is connected.

  In step S5, display processing is performed. In the display process, various display processes such as water depth display are performed. In step S6, it is determined whether any button of the operation key unit 99 or the adjustment lever 101 is operated. In step S7, it is determined whether or not the spool 3 is rotating. This determination is made based on the output of the spool sensor 102. In step S8, the power supply voltage detection process shown in FIG. 20 for monitoring voltage abnormality is performed. In step S9, it is determined whether or not the water depth data LX calculated from the output of the spool sensor 102 exceeds 6 m. In step S10a, when the water depth data LX is 6 m or less, it is determined whether or not the spool 3 has stopped for more than 6 seconds. In step S10b, it is determined whether or not there is a request for transmission to the fish finder monitor 120. In step S11, it is determined whether any of the three lead wires 152a, 152b, 152c of the potentiometer 104 connected to the adjustment lever 101 is disconnected. This determination is made based on the voltage output from the potentiometer 104 as described above. In step S12, it is determined whether any other command or input has been made. When these determinations are finished, the process returns to step S5.

  When key input is performed by the operation key unit 99 or the adjustment lever 101, the process proceeds from step S6 to step S13, and the key input process shown in FIG. 16 is executed. When the rotation of the spool 3 is detected, the process proceeds from step S7 to step S14. In step S14, each operation mode process shown in FIG. 18 is executed. When the water depth data LX exceeds 6 m, the process proceeds from step S9 to step S15. In step S15, it is determined whether or not the device stop time at the water depth LX exceeds 6 seconds. If it is longer than 6 seconds, it is considered that the device has stopped on the shelf, so the process proceeds to step S16 and the water depth LX is set at the shelf position M. When the water depth data LX is 6 m or less and the spool 3 has stopped for more than 6 seconds, it is considered that the device has stopped at the ship's edge. For this reason, the process proceeds from step S10a to step S17, and the water depth data LX is set to the ship edge yarn length FB. If there is a transmission request, the process proceeds from step S10b to step S18. In step S18, the requested data is transmitted to the fish finder monitor 120. For example, the water depth data LX and items set on the reel side are transmitted to the fish finder monitor 120. If it is determined that the lead wires 152a, 152b, 152c of the potentiometer 104 are disconnected, the process proceeds from step S11 to step S19, and the alarm display to that effect is replaced with, for example, the water depth display portion 98a of the water depth display unit 98. Thus, for example, the characters Err5, Err6, and Err7 are displayed in correspondence with the disconnected lead wires 152a, 152b, and 152c. If any other command or input is made, the process proceeds from step S12 to step S20 to execute other processes.

  In the key input process in step S13 of FIG. 15, it is determined whether or not the stage ST operated by the adjustment lever 101 in step S21 is 0, as shown in FIG. Here, when the stage ST is 0, the process proceeds to step S22 and the motor 4 is stopped (turned off). In addition, when already stopped, the stopped state is maintained as it is. In step S23, it is determined whether or not the menu button MB has been operated. In step S24, it is determined whether or not the enter button DB has been operated. In step S25, it is determined whether or not the fast winding button HB has been operated. In step S26, it is determined whether another key operation, for example, an operation such as setting a learning mode by operating the memo button TB or operating the memo button MB and the fast-winding button HB for a predetermined time has been performed.

  If the stage ST of the adjustment lever 101 is not 0, the process proceeds from step S22 to step S27. In step S27, it is determined whether or not the water depth data LX is 0 or less. In this embodiment, in order to protect the tip of the fishing rod, in the state where the ship's edge mode (mode in which the spool winding is automatically stopped in a state where the device is easily collected) is set, the water depth can be adjusted even if the adjustment lever 101 is operated. When the data LX is 0 or less, no further winding is possible. As described above, the ship edge mode is automatically set when the spool 3 is stopped for a predetermined time (for example, 6 seconds) or more when the water depth data LX is 6 m or less. When the water depth data LX is not 0 or less, the process proceeds to step S28, and the motor driving process shown in FIG. 17 is executed. When the water depth data LX is 0 or less, the process proceeds from step S27 to step S29. In step S29, it is determined whether or not the ship edge mode is set. When it is not the ship edge mode, the process proceeds to step S28 to execute the motor driving process. In the ship edge mode, the process proceeds to step S30, and the adjustment lever 101 is moved twice in a predetermined time (for example, 3 seconds) toward the stage ST = 0 which is the swing start position (that is, three or more different directions). It is determined whether or not a rocking operation has been performed. By this special click operation, the spool 3 can be driven in the winding direction even in the ship edge mode and when the water depth data LX is 0 or less. Accordingly, when it is determined that the click operation has been performed, the process proceeds to step S28 to execute the motor driving process. If the click operation has not been performed, no processing is performed to prohibit the motor drive, and the process proceeds to step S23.

  When the menu button MB is operated, the process proceeds from step S23 to step S31, and the item of the character or shelf position displayed on the water depth display unit 98 is moved while blinking to select an item.

  When the determination button DB is operated, the process proceeds from step S24 to step S32. In step S32, it is determined whether or not the enter button DB has been pressed for 3 seconds or longer. When it is not long press, it transfers to step S33. In step S33, the selected item is determined and the process proceeds to step S34. In step S34, it is determined whether or not the determined item needs to be transmitted to the fish finder monitor 120. If it is necessary to transmit, the process proceeds to step S35 to request transmission of the item, and if not required, step S35 is skipped and the process proceeds to step S25. On the other hand, if it is determined that the button is pressed long, the process proceeds from step S32 to step S36. In step S36, the current water depth data LX is set to 0 as a reference yarn length serving as a reference for the yarn length. Thus, the subsequent water depth is displayed by setting the water depth data LX at the set position to 0, and the yarn length thereafter.

  When the fast winding button HB is operated, the process proceeds from step S25 to step S37. In step S37, it is determined whether or not the water depth data LX is less than the ship edge yarn length FB. When the water depth data LX is equal to or larger than the ship edge yarn length FB, the process proceeds to step S38, and it is determined whether or not a prohibition flag FP for prohibiting driving of the motor 4 set in the power supply voltage detection process described later is set (ON). to decide. When the prohibition flag FP is not set, the process proceeds to step S39, the first duty ratio D1 is set to 95%, for example, and the motor 4 is driven at the highest speed. When the water depth data LX is less than the ship edge yarn length FB, the process proceeds to step S26 in order to invalidate the operation by the fast winding button HB. When other key inputs such as a memo button TB or an operation to enter a bobbin learning mode are performed, the process proceeds from step S26 to step S40 to perform a key input process according to the operation and return to the main routine.

  In the motor driving process by the adjustment lever 101 in step S28 of FIG. 16, the rotation speed of the spool 3 (an example of the rotation speed of the motor 4) is detected and the motor 4 is controlled at a constant speed when the stage ST is from the first stage to the fourth stage. From step 5 to step 30, the motor 4 is torque-controlled so that the tension acting on the fishing line is constant. In the motor driving process, as shown in FIG. 17, it is determined whether or not the prohibition flag FP described above is set in step S41a. If the prohibition flag FP is set, this process ends and the process returns to the key input process. If the prohibition flag FP is not set, the process proceeds to step S41b. In step S41b, it is determined whether or not the stage ST based on the swing angle of the adjustment lever 101 is any one of 1 to 4 stages. This determination is made based on the voltage of the signal output from the potentiometer 104. In step S42, it is determined whether the stage ST is any of 5 to 30 stages.

  When the stage ST is 1 to 4, the process proceeds from step S41 to step S43. In step S43, the speed V output from the spool sensor 102 is captured. In step S44, it is determined whether or not the speed V of the spool 3 is less than the lower limit speed Vst1 corresponding to the stage ST. In step S45, it is determined whether or not the speed V of the spool 3 exceeds the upper limit speed Vst2 corresponding to the stage ST. It should be noted that the stage ST in which the speed control is performed is 1 to 4 and the lower limit speed Vst1 and the upper limit speed Vst2 are provided for each stage ST when the speed varies between the speeds Vst1 and Vst2. This is because there is no change in wowing in which the duty ratio fluctuates frequently, and feedback control is stabilized. The upper limit speed Vst2 and the lower limit speed Vst1 are set within, for example, ± 10% of the target speed Vst.

  When the speed V is less than the lower limit speed Vst1, the process proceeds from step S44 to step S46, and the current first duty ratio D1 is read. The first duty ratio D1 is stored in the storage unit 107 every time the setting is changed. In addition, the maximum value DUst and the minimum value DLst are set for each stage ST. When the stage ST is initially set, for example, the intermediate first duty ratio D1 = ((DUst + DLst) / 2) is set. Is done. In step S47, it is determined whether or not the current first duty ratio D1 exceeds the set maximum value DUst. When exceeding, the process proceeds to step S48, and the maximum value DUst is set to the first duty ratio D1. If not, the process proceeds from step S47 to step S49, the first duty ratio D1 is increased by a predetermined increment DI (for example, 1%), and the process proceeds to step S45. The maximum value DUst at the highest stage (ST = 4) is also set to 85% or less. Therefore, the upper limit of the adjustment operation by the adjustment lever 101 is a duty ratio of 85%.

  When the speed V exceeds the upper limit speed Vst2, the process proceeds from step S45 to step S50, and the current first duty ratio D1 is read. The first duty ratio D1 is the same as that in step S46. In step S51, it is determined whether or not the current first duty ratio D1 is below the minimum value DLst at which the current first duty ratio D1 is set. If it is below, the process proceeds to step S52, and the minimum value DLst is set to the first duty ratio D1. If not, the process proceeds from step S51 to step S53, the first duty ratio D1 is reduced by a predetermined decrement DI (for example, 1%), and the process proceeds to step S42.

  When the stage ST is 5 to 30 stages, the process proceeds from step S42 to step S54. In step S54, the first duty ratio D1 is set to the duty ratio Dst corresponding to the stage ST. As a result, when the stage ST is 5 to 30 stages, the current flowing through the motor 4 is controlled to increase at each stage, and the motor 4 is torque controlled. The duty ratio Dst corresponding to each stage ST is a value at a reference bobbin diameter (for example, spool body diameter) with respect to the stage ST, and the duty ratio Dst is stepwise in proportion to the bobbin diameter as the bobbin diameter increases. Gradually grows. Thereby, the torque increases according to the bobbin diameter, and the tension of the fishing line where the torque increases as the bobbin diameter increases becomes substantially constant. The maximum value DUst at the highest stage (ST = 4) of constant speed control and the maximum duty ratio at the highest stage (ST = 30) of torque control are set to 85% or less. Therefore, the upper limit of the adjustment operation by the adjustment lever 101 is a duty ratio of 85%.

  In each operation mode process in step S14 in FIG. 15, as shown in FIG. 18, it is determined in step S611 whether or not the rotation direction of the spool 3 is the yarn unwinding direction. This determination is made based on which Hall element of the spool sensor 102 has emitted a pulse first. If it is determined that the rotation direction of the spool 3 is the yarn feeding direction, the process proceeds from step S61 to step S62. In step S62, every time the count value of the pulse output from the spool sensor 102 decreases, data indicating the relationship between the water depth and the count value stored in the reel control unit 100 is read based on the count value, and the water depth data LX is calculated. To do. This water depth data LX is displayed in large 7-segment characters in the central portion of the water depth display unit 98 in the display process of step S5. In step S63, a transmission request for the water depth data LX is made.

  In step S64, it is determined whether or not the yarn feed mode is set. In step S65, it is determined whether or not the shelf stop mode. In step S66, it is determined whether or not another mode is selected. If it is not in another mode, each operation mode process is terminated and the process returns to the main routine.

  In the yarn feed mode, the process proceeds from step S64 to step S67. In step S67, it is determined whether or not the water depth LX exceeds 6 m. In the line feed mode, the motor 4 is not normally rotated from the beginning, but waits for the fishing line to be fed to a water depth at which it can be determined that the fishing line has been reliably fed. When the water depth data LX exceeds 6 m, the process proceeds to step S68 and the motor 4 is rotated forward. As a result, as described above, the friction between the planetary gear mechanism 40 and the spool 3 is reduced, and the spool 3 rotates in the yarn unwinding direction at a higher speed. When the water depth data LX is 6 m or less, step S68 is skipped.

  The process proceeds from step S65 for determining the shelf stop mode to step S69. In step S69, it is determined whether the obtained water depth data LX coincides with the shelf position M, that is, whether the device has reached the shelf. The shelf position is set by pressing the memo button TB when the device reaches the shelf, in addition to the above-described automatic setting by stopping for a predetermined time or more. When the device reaches the shelf position, the process proceeds from step S69 to step S70. In step S70, the buzzer 106 is sounded to notify that the device is on the shelf. In step S71, the motor 4 is reversely rotated for a predetermined time. At this time, as shown in FIG. 21, the duty ratio is gradually increased from the second duty ratio D2 to the third duty ratio D3, and the voltage applied to the motor 4 is gradually increased. As a result, excessive torque due to impact is less likely to act on the mechanism mounting shaft 75, and the mechanism mounting shaft 75 mounted on the output shaft 30 of the motor 4 is less likely to idle. Due to the reverse rotation of the motor 4, the clutch mechanism 7 is returned to the clutch-on state by the first clutch return mechanism 11 via the clutch switching mechanism 8 in the above-described operation. As a result, the rotation of the spool in the yarn unwinding direction stops. If the water depth data LX has not reached the shelf position M, steps S70 and S71 are skipped. If it is determined that the mode is another mode, the process proceeds from step S66 to step S72, and the set other mode processing is executed.

  When the rotation of the spool 3 is determined to be the yarn winding direction, the process proceeds from step S61 to step S73. In step S73, every time the count value of the spool sensor 102 increases, the data stored in the reel control unit 100 is read and the water depth data LX is calculated. This water depth is displayed in the display process of step S5. In step S74, a transmission request is output as in step S63. In step S75, it is determined whether or not the auto rewind mode is set. This automatic pitching mode can be set on the electric reel 1 or the fish finder monitor 120. When this auto rewind mode is set, it is possible to set a replay width that is a range in which the replay operation of the auto replay mode is performed and a replay pattern according to the interval at which the motor 4 is turned on / off.

  When the saddle width is set, as shown in FIG. 22, the saddle width SA is displayed at the position corresponding to the water depth as shown by hatching on the fish finder monitor 120 side. In addition, the fish finder monitor 120 displays information such as the shelf position TL output from the fish finder 140, the device position FL based on the water depth data LX, and the seabed BL. Further, on the menu screen on the fish finder monitor 120 side, various settings on the electric reel 1 side including the automatic pitch setting AS and the pitch width SA can be performed as shown in FIG. It is also possible to perform a rewind operation from an arbitrary position by operating the replay button 134.

  In step S76, it is determined whether or not the ship edge mode is set. In step S77, it is determined whether or not the water depth data LX is negative.

  If it is determined that the auto rewind mode is set, the process proceeds from step S75 to step S78. In step S78, the automatic pitching process shown in FIG. 19 is executed. In this automatic rewinding process, a rewinding operation for turning on and off the motor 4 is performed within a range set from the shelf position M by the set rebound speed. Specifically, it is determined in step S90 of FIG. 19 whether or not the water depth data LX has been wound up beyond the shelf width M from the shelf position M. If the device is within the ramp width SA, the process proceeds to step S91. In step S91, it is determined whether or not the variable N for setting the number of times of feeding is 0. When this variable N is 0, it means that the scouring is performed for the first time. When the variable N is 0, the process proceeds to step S92 and the variable N is set to 1. When the variable N is not 0, this process is skipped. In step S93, it is determined whether or not the water depth data LX has reached a position (LX = M−N * L) at which the motor 4 is turned off by the rewinding operation. Here, the variable L is a value that varies depending on the pitch pattern. When the device reaches the saddle position, the process proceeds to step S94, and the motor 4 is stopped for a predetermined time. In step S95, the variable N is incremented by 1 to place the device at the next jump position. If the device has passed the saddle width, the process proceeds to step S96 where the variable N is cleared to 0 and the process returns to each mode operation process. In this embodiment, the spool 3 is wound at the same interval and at the same stop time according to the number of times of auto-saw. However, the saddle pattern is not limited to this, and may have unequal intervals and variable stop times.

  If it is determined that the ship edge mode is set, the process proceeds from step S76 to step S79. In step S79, it is determined whether the water depth matches the boat edge stop position. If it has not been wound up to the ship edge stop position, the process proceeds to step S77. When the ship edge stop position is reached, the process proceeds from step S79 to step S80. In step S80, the buzzer 106 is sounded to notify that the device is on the shore. In step S81, the motor 4 is turned off. As a result, the fish is arranged at a position where it can be easily taken when the fish is caught. As described above, the ship edge stop position is set when the spool 3 is stopped for a predetermined time or more at a water depth of 6 m or less, for example. When the water depth is less than 0, the process proceeds from step S77 to step S82. In step S82, the buzzer 106 is leveled to notify that the device has been wound too much. In step S83, the motor 4 is turned off and the process returns to the main routine.

  In the power supply voltage detection process in step S15 of FIG. 15, the power supply voltage PV is captured in step S100 of FIG. In step S101, for example, it is determined whether or not the motor 4 is rotating based on the current flowing through the motor 4. If the motor 4 is not rotating, the process proceeds to step S102. In step S102, it is determined whether or not power supply voltage PV has exceeded allowable maximum voltage Vh2 (for example, 18 volts). When the power supply voltage PV exceeds the allowable maximum voltage Vh2, the process proceeds from step S102 to step S103. In step S103, it is determined whether or not a timer T1 for measuring a time exceeding the allowable maximum voltage Vh2 has already been set. For example, when a common power source is used for a plurality of electric reels for boat fishing, the timer T1 can eliminate a voltage increase due to an instantaneous inrush voltage. When the timer T1 has not been set yet, the process proceeds to step S104 and the timer T1 is set. The value of the timer T1 is preferably in the range of 0.1 second to 1 second, for example. If it is in such a range, even if the voltage rise continues, for example, it becomes difficult to cause damage to the electrical equipment. If the timer T1 has already been set, step S104 is skipped. In step S105, it is determined whether or not the timer T1 has timed up, that is, whether or not the power supply voltage PV has continuously exceeded the allowable maximum voltage Vh2 for the time T1. When the power supply voltage PV continues to exceed the allowable maximum voltage Vh2 for the time T1, the process proceeds to step S106, and instead of the water depth display, for example, the characters Err1 are displayed in the water depth display portion 98a of the water depth display portion 98. In step S107, a prohibition flag FP is set (on) to disable the operation of the motor 4 by disabling the operation of the adjustment lever 101 and the fast winding button HB on the motor 4 until the power supply voltage drops below the maximum allowable voltage Vh2. ) In step S108, the timer T1 is reset and the process proceeds to step S111.

  When the power supply voltage PV is equal to or lower than the allowable maximum voltage Vh2, the process proceeds from step S102 to step S109. In step S109, it is determined whether or not the prohibition flag FP is set. Thereby, it is determined whether or not the state is prohibited due to the voltage excess. If the prohibition flag FP is set, the process proceeds to step S110, the prohibition flag FP is reset (turned off), and the process proceeds to step 111. That is, when the power supply voltage PV becomes the allowable maximum voltage Vh2 or less in the motor drive prohibited state, the motor drive prohibition is released.

  In step S111, it is determined whether or not the power supply voltage PV has dropped below an allowable minimum voltage (for example, 9 volts) Vm. If the power supply voltage PV is equal to or higher than the allowable minimum voltage, the process returns to the main routine. When the power supply voltage PV falls below the allowable minimum voltage Vm, the process proceeds from step S111 to step S112. In step S112, it is determined whether or not the timer T2 for measuring the time during which the allowable voltage Vm is lower is already set. By this timer T2, for example, an instantaneous voltage drop due to an increase in load can be eliminated. When the timer T2 has not been set yet, the process proceeds to step S113 to set the timer T2. The value of the timer T2 is preferably in the range of 0.1 second to 1 second, for example. Within such a range, an instantaneous voltage drop can be reliably eliminated. If the timer T2 has already been set, step S113 is skipped. In step S114, it is determined whether or not the timer T2 has expired, that is, whether or not the power supply voltage PV has continued to fall below the allowable minimum voltage Vm for the time T2. When the power supply voltage PV continues to fall below the allowable minimum voltage Vh2 for the time T2, the process proceeds to step S115, and the power supply graphic 98c of the water depth display unit 98 is blinked, for example. In step S116, the timer T2 is reset and the process returns to the main routine.

  As described above, in this electric reel, only when the interlock mechanism 89 is operated by reverse rotation of the motor 4 to return to the clutch-on state, the interlock mechanism 89 is pressed by the pressing mechanism 88 to separate the pressing mechanism 88. Therefore, the motor 4 and the interlocking mechanism 89 need not always be interlocked. For this reason, when the clutch switching mechanism 8 is manually operated to switch the clutch mechanism 7 from the clutch-off state to the clutch-on state, the motor 4 does not rotate, and a manual return operation is facilitated.

  When the motor 4 rotates forward, the claw control mechanism 84 swings the swing claw 82 to a position where the claw wheel 81 is displaced, so that the swing claw 82 for preventing reverse rotation does not vibrate when the motor 4 rotates forward. Silence can be achieved.

  Furthermore, since the roller clutch 90 is interposed between the pressing member 91 of the pressing mechanism 88 and the output shaft 30 so that the forward rotation of the output shaft 30 is not transmitted to the pressing member 91, in the yarn feeding mode, Even if the pressing member 91 comes into contact with the interlocking mechanism 89, it is not pressed, and the yarn feeding mode can be carried out smoothly.

  Furthermore, since the voltage applied to the motor 4 is gradually increased from the first voltage V1 to the second voltage V2 during the clutch return operation due to the reverse rotation of the motor 4, it is shocking from the start of rotation to the start of the switching operation. An excessive force is not applied to the mechanism mounting shaft 75 fixed to the output shaft 30 of the motor 4 without being a torque load, and the mechanism mounting shaft 75 can be prevented from idling.

  Further, when the power is turned on, the power supply voltage is detected, and when the power supply voltage is high, the first, second, and third duty ratios D1, D2, and D3 are corrected according to the detected power supply voltage. For this reason, each duty ratio becomes a smaller value than before correction, and even if the power supply voltage increases, the rotation state of each setting stage of the motor 4 during forward rotation and the rotation state during reverse rotation are made as constant as possible. Can be maintained. Moreover, since the power supply voltage is detected immediately after the power is turned on, it is possible to quickly recognize that a different type of power supply is connected by comparing the detected power supply voltage with a predetermined voltage.

  In addition, the motor 4 can be driven in the yarn winding direction from the reference yarn length by a special operation that is unlikely to malfunction, such as a click operation to the swing start position within a predetermined time of the adjustment lever 101 even when the ship edge mode is set. For this reason, the spool 4 can be rotated from the reference yarn length to the winding side while preventing damage to the tip due to an erroneous operation.

  Further, since the abnormality of the power supply voltage is determined based on the power supply voltage when the motor 4 is not rotating, the rotation of the motor 4 does not stop due to the abnormality of the power supply in use. In addition, since the determination on the power supply voltage is always performed when the motor 4 is not rotating, it is possible to prevent damage to the equipment due to an abnormality in the power supply voltage in use.

  Furthermore, in the low stages up to the first M stages (for example, 4 stages) out of the N stages, the motor is speed controlled so that the detected speed is the target speed set so that the speed is increased at each stage. Therefore, at a low stage, the motor is controlled to a target speed corresponding to each stage. In addition, at a high stage (for example, 5 to 30 stages), the motor is torque-controlled. For this reason, at a low stage, the rotation of the motor is difficult to stop even if the load is large, and the motor is difficult to rotate at high speed even if the load is small. Therefore, the rotation of the motor is stabilized at a low stage.
