In the conventional electric reel, when a large load acts at a low stage where the set torque is small, the motor may be difficult to rotate. In particular, if the set torque is increased by using the lever as the operation member and the set torque is finely divided, the motor may become difficult to rotate depending on the load in the low divided step. If the load is small even at a low level, there is a fear that the spool will rotate at a speed higher than the angler can imagine.

An object of the present invention is to stabilize a rotation of a motor in a low stage in a motor control apparatus for an electric reel that controls a motor with a plurality of stages of set torque.

A motor control apparatus for an electric reel according to the first aspect of the present invention is a motor control apparatus for an electric reel that drives a spool rotatably mounted to a reel unit with a motor, the rotational speed detecting means, the rotational state operating means, and the first A control means is provided. The rotational speed detecting means is a means for detecting the rotational speed of the spool. The rotation state operating means is a means for operating the rotation state of the motor in N (N: integer of 2 or more) steps. The first control means detects the speed detected by the rotational speed detecting means at a target speed set to be faster for each step in the first rotational state up to the first M (M: N / 2 or less) stage in the rotational state of the N stages. The motor is speed-controlled so that it becomes, and in the following second rotation state from the M + 1 stage to the N stage, it is a means of torque controlling the motor so that the torque of the motor becomes the torque set so that it may become large every step.

In this motor control apparatus, when the rotational state operating means is operated so that the rotational state is set to any one of the plurality of stages, in the first rotational state up to the first M stage, the target speed at which the detected motor speed is set for each stage is increased. The motor is speed controlled as much as possible. In the second rotational state from the M + 1 stage to the final N stage, the motor is torque controlled so that the torque of the motor becomes the set torque. Here, in the low stage up to the first M stage among the N stages, since the motor is speed-controlled so that the detected speed becomes the target speed set to increase the speed for each stage, in the low stage, at the target speed according to each stage, The motor is controlled. Also at high stages, the motor is torque controlled. For this reason, in the low stage, even if a load is large, rotation of a motor becomes difficult to stop, and even if a load is small, a motor becomes difficult to rotate at high speed. Therefore, the rotation of the motor is stabilized at low stages.

In the motor control apparatus for an electric reel according to the second aspect of the invention, the rotational state operating means includes a lever member mounted to the reel main body so as to be able to swing within a predetermined range, and a swinging position detecting means for detecting the swinging position of the lever member. The first control means divides the detection result of the swing position detecting means into N stages to perform speed control and torque control. In this case, even if the rotational state is finely divided and controlled by the swinging position of the lever member, the rotation of the motor is stabilized at a low level.

The motor control apparatus for an electric reel according to the third aspect of the invention is the apparatus according to the first aspect or the second aspect, further comprising motor driving means for driving the motor with pulse width modulated power, and the first control means provides a duty ratio. To control the motor drive means. In this case, since the motor can be PWM controlled, the motor can be easily controlled according to the speed or torque.

The motor control apparatus for an electric reel according to the fourth aspect is the apparatus according to the third aspect, in which the first control means controls the motor drive means at a duty ratio set according to each step in the second rotation state. In this case, the torque is not controlled to the target torque but controlled to the set duty ratio, i.e., the current value, so that the control is simplified and it is difficult to produce the howling in which the duty ratio frequently changes.

In the motor control apparatus for an electric reel according to the fifth aspect, in the apparatus according to the fourth aspect, the set duty ratio is set so as to change in accordance with the winding diameter wound on the spool. By increasing the set torque accordingly when the winding diameter becomes large, the motor can be controlled so that the tension becomes constant for each step. Thus, the constant tension control can be realized with simple control.

The motor control apparatus for an electric reel according to the sixth aspect is the apparatus according to any one of the inventions 1 to 3, further comprising torque detecting means for detecting a torque acting on the motor, wherein the first control means includes: In the second rotation state, the motor is torque controlled so that the detected torque becomes a target torque set in accordance with each step. In this case, since the feedback control is performed so that the detected torque becomes the set torque, the accuracy in torque control is improved.

In the motor control apparatus for an electric reel according to the seventh aspect, in the apparatus according to the sixth aspect, the torque to be set is set to change in accordance with the winding diameter wound on the spool. In this case, since the motor can be controlled so that the tension becomes constant every step by increasing the target torque set accordingly when the winding diameter becomes large, tension constant control can be implemented with control with high precision.

The motor control apparatus for an electric reel according to the eighth aspect is the apparatus according to any one of the inventions 2 to 7, wherein the line length measuring means for measuring the line length of the fishing line discharged from the spool and the line length reference Reference line length setting means for setting the reference line length to be used, and when the motor is driven in the line winding direction by the first control means, the motor is stopped at the reference line length with reference to the measurement result of the line length calculating means, And a second control means for starting the drive of the file winding direction of the motor further from the reference file length by the rocking operation in another direction that is continuous three or more times within a predetermined time of the lever member.

In this motor control apparatus, when a lever member is operated, a motor is controlled as mentioned above according to the swing position, and the rotation state of a spool changes. Further, when the fishing line is wound up by the operation of the lever member in the state where the reference line length is set, the rotation of the motor stops at the reference line length. In this state, it is impossible to rotate the motor toward the bobbin winding side in the normal lever member operation. However, by performing a special operation of operating the lever member three times within a predetermined time, it is possible to rotate the motor from the reference line length to the file winding side. Here, the motor can be driven from the reference string length to the string winding direction by a special operation that is difficult to malfunction, such as a rocking operation in another direction three or more times within a predetermined time of the lever member. For this reason, it is possible to rotate the spool from the reference file length to the file winding side while preventing the breakage of the repair due to an incorrect operation.

Further, the second motor control means stops the motor even in the length of the delivery line, and when the delivery setting means is setting the length of the delivery line, the second motor control means moves from the reference line length by the oscillation operation in the direction of the winding direction of the motor. Start the drive. In this case, when the length of the delivery string is not set, it can be rolled up from the reference line length to the line winding side, thereby improving the operability of the motor except when fishing is actually performed.

The motor control apparatus for an electric reel according to the tenth aspect is the apparatus according to the eighth or ninth aspect, wherein the second control means is formed from the reference string length by two swing operations within a predetermined time to the swing start position of the lever member. The drive of the motor winding direction is started. In this case, since the motor can be driven by two operations to the swing start position that is easy to position without looking at the lever member, the special operation can be performed without further misoperation.

The motor control apparatus for an electric reel according to the eleventh aspect is the apparatus according to any one of the eighth to tenth aspects, wherein the second control means swings the position of the lever member when the motor is subjected to the winding of the motor from the reference string length. Regardless of whether you drive the motor at a given speed. In this case, when driving from the reference line length to the line winding side, the motor is driven at a predetermined speed, making it easy to predict the stopping timing of the motor. In addition, when the predetermined speed is set at a low speed, it is easier to prevent damage to the waterline.

The motor control apparatus for an electric reel according to the twelfth aspect is the apparatus according to any one of the eighth to eleventh aspects, wherein the first control means stops the motor when the lever member is located at the swing start position. In this case, since the operation member for on / off of a motor may not be provided separately, operation becomes easy.

As for the motor control apparatus of the electric reel which concerns on invention 13, the apparatus in any one of inventions 3-12, The duty ratio in the swing end position of a lever member is less than 96%. In this case, since the maximum duty ratio set by the lever member is considerably suppressed than 100%, even if the lever member is operated to the swing end position, malfunction by heat of the motor is unlikely to occur.

The motor control apparatus for an electric reel according to the fourteenth invention is the apparatus according to any one of the inventions 2 to 13, which invalidates the first control means when the power feeding to the motor is returned after the power feeding to the motor is stopped. When the lever member is in a position where the lever member is oscillated by the rotation invalid means by the rotation invalid means and the rotation control means becomes invalid by a predetermined oscillation range or more from the oscillation start position, It is provided with the rotation return means which makes a 1st control means effective when the operation | movement to the reverse direction of a lever member is performed after performing operation.

In this motor control apparatus, for example, when the cord is disconnected from the reel or the battery and the power supply to the motor is stopped, and the cord is connected to return the power supply to the motor, the first control means, i.e. Operation of the lever member is invalidated under predetermined conditions. When the motor is driven again, the first control means is made effective by swinging the lever member in the deceleration direction in a deceleration direction and then swinging the lever member in the deceleration direction. Here, after performing the rocking operation of the lever member in the deceleration direction or more in the deceleration direction, rocking the gear member in the deceleration direction so as to drive the motor again without causing the lever member to swing to the stop position (swing start position) as in the prior art. can do. Therefore, the operability of the lever member at the time of driving a motor can be improved.

The motor control apparatus according to the fifteenth aspect is the motor control apparatus according to the sixteenth aspect, wherein the rotation return means has a predetermined swing range from the swing start position when the first control means is invalidated by the rotation invalidation means. When it is in the lesser position, the first control means is effective when the lever member is returned to the swing start position. In this case, when the lever member is in a position less than the predetermined swing range, the first control means is effective when the lever member is returned to the stop position, so that the lever member is only slightly rotated when the motor is restarted. In addition, the operability of the lever member can be further improved.

The motor control apparatus according to the sixteenth aspect of the invention is the motor control apparatus according to the sixteenth or fifteenth aspect, wherein the rotation return means returns to the swing start position when the power supply to the motor is returned after the power supply to the motor is stopped. If there is, the first control means is made effective. In this case, by making the rotation control means effective when the operation member is in the stop position, the operation of returning the lever member when the motor is driven again becomes unnecessary, and the operability of the operation member can be further improved.

In the motor control apparatus according to the seventeenth aspect of the invention, in the motor control apparatus according to any one of the inventions 14 to 16, the predetermined range is 5 degrees or more and 45 degrees or less, preferably 20 degrees or more and 40 degrees or less. to be. In this case, for example, when the swinging range of the operating member is in the range of 0 degrees to 140 degrees, the predetermined range is in the range of 5 degrees to 45 degrees, preferably in the range of 20 degrees to 40 degrees, for example By setting it as 30 degree | times, since the fluctuation | variation of the operation member can be reduced, re-drive of a motor can be performed quickly.

[Overall Configuration of Electric Reel]

The electric reel 1 is fixed to the fishing rod R attached to the boat FB of the fishing boat by the rod support RK, for example. As shown in FIG. 2, the electric reel 1 mainly includes a reel main body 2 to which the handle 2a is mounted, a spool 3 rotatably mounted to the reel main body 2, and a spool 3.

Further, an adjustment lever 101 for variably rotating the spool 3 on the front side of the reel unit 2 and a clutch operation for on / off operation of the clutch mechanism 7 (to be described later) on the rear side. The levers 50 are mounted so as to be swingable, respectively.

The adjustment lever 101 is rotatably mounted in a range of approximately 140 degrees, and a potentiometer 104 (see FIG. 3) for detecting a swing angle is connected to a swing shaft (not shown) of the adjustment lever 101. . This potentiometer 104 can detect the rotation angle in the range of 0 degree to 270 degree, for example, and detects the rocking angle of the adjustment lever 101 in the range of 50 degree to 190 degree. 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 according to the swing angle detected by the potentiometer 104.

In other words, when the lead wires 152a and 152c are disconnected, the lever angle signal is 0 volts. Further, if the value of the resistor 154 is 1 MΩ and the maximum value of the variable resistor 110 is 5 kΩ, when the lead wire 152b is disconnected, the combined resistance (1 MΩ / (1 MΩ + 5 kΩ)) becomes approximately 1, The output signal is 5 volts. On the other hand, when the lead wire 152b is not disconnected, since the potentiometer 104 fluctuates only in the range of 50 degrees to 170 degrees, only a signal having a voltage lower than 5 volts is output. Therefore, when such a value is output during operation, disconnection of the lead wires 152a, 152b, and 152c can be determined.

Also, in step 31, the motor 4 is turned off in the step (ST = 0) disposed at the very front side where no operation is performed. In the following example, the feedback speed for controlling 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 step by step in the fourth step (ST = 1 to 4). Control is performed. In the remaining 26 steps (ST = 5 to 30), the motor 4 is controlled by the first duty ratio D1 which is large for each step ST and corrected according to the winding diameter. Thereby, the spool 3 does not stop rotating even if high load acts by speed control in the first four steps of speed. In addition, in the remaining 26 steps after that, since it controls by the constant 1st duty ratio D1 corrected by the winding diameter for every step, the tension acting on the spool 3 becomes substantially constant, and a collar | collar break etc. arises. Becomes difficult. In addition, in operation of the adjustment lever 101, even in the maximum stage, the 1st duty ratio D1 does not exceed 85%. In the operation of the fast forward button HB, for example, the motor 4 is driven at high speed with the first duty ratio D1 of 95% at maximum. Thereby, malfunction by overheating of the motor 4 can be prevented beforehand.

In addition, the reel control unit 100 calculates the depth of the gear attached to the tip of the fishing line by the output of the spool sensor 102, and displays it on the depth display portion 98a. Further, when the bottom position or the fish habitat layer position is set by the operation of the operation key unit 99, when the prepared depth reaches the fish habitat layer position or the bottom position by matching the calculated bottom position or the fish habitat layer position, The motor 4 is rotated in reverse to operate the clutch switching mechanism 8 via the first clutch return mechanism 11 to return the clutch mechanism 7 to the clutch on state. Thereby, the gear is arrange | positioned at the position.

The storage unit 107 stores a plurality of map data for converting the count value for each predetermined pulse of the spool sensor 102 into the depth data LX of the gear on the various fishing lines. The plurality of map data considers that the coefficient value and the water depth data LX change depending on the rope diameter and the winding diameter. Map data is previously stored in the storage unit 107 for a plurality of fishing lines frequently used in the electric reel 1 of that size. Moreover, about the fishing line which is not memorize | stored previously, map data are produced | generated by learning, and it is made to memorize | store in the memory | storage part 107.

When the count value of the spool sensor 102 is output, the reel control unit 100 outputs the depth data of the display for display based on the map data of the fishing line selected from the plurality of map data stored in the storage unit 107 based on the count value ( LX is calculated and the calculated depth data LX is displayed on the depth display unit 98. When the sonar monitor 120 is connected to the sonar monitor 120, various types of information including the water depth data LX of the equipment are output to the sonar monitor 120 through the communication lines of the information communication unit 105 and the power cord 130.

In addition, during the clutch return operation due to the reverse rotation of the motor 4, as shown in FIG. 21, the reel control unit 100 sets the duty ratio applied to the motor driving circuit 108 in the second duty ratio D2. 3 Raise slowly to duty ratio (D3). As a result, the voltage applied to the motor 4 gradually rises from the first voltage V1 to the second voltage V2. In addition, the range of 2 volts to less than 6 volts is preferable for the 1st voltage V1 here, for example. The second voltage V2 is preferably in the range of 6 volts to 12 volts at a voltage at which the pressing member 91 (described later) can press the retreating member 96 due to the reverse rotation of the motor 4. The second duty ratio D2 needs to be changed according to the power supply voltage PV, but 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. Do. In addition, the third duty ratio D3 is preferably in the range of 50% to 100%. Thereby, the mechanism mounting shaft 75 fixed to the output shaft 30 at the time of reverse rotation of the motor 4 becomes difficult to idle.

In addition, when the power supply voltage PV is 15 volts using a lithium battery, the duty ratios D1, D2, and D3 are corrected to a value of 12/15, for example, to correct an increase in the power supply voltage PV. . As a result, even when a storage battery having a higher power supply voltage than a lead battery such as a lithium battery or a nickel hydride battery is used, the voltage applied at the time of forward rotation of the motor 4 by the operation of the adjustment lever 101 and at the start of reverse rotation The first and second voltages V1 and V2 applied to the motor 4 become difficult to fluctuate, and the fluctuation of the speed and torque at the time of forward rotation of the motor 4 by the operation of the adjusting lever 101 decreases. The mechanism mounting shaft 75 fixed to the output shaft 30 at the time of reverse rotation of the motor 4 becomes harder to idle.

Here, the roller clutch 90 is attached to the pressing member 91 when the interlocking mechanism 89 is in the line-off mode in which the interlocking mechanism 89 rotates forward and closes the pressing member 91 in the clutch off state. This is to prevent a problem from occurring even when the pressing member 91 contacts the interlocking mechanism 89. The pressing member 91 rotates when the motor 4 reversely rotates and the rotation is transmitted through the roller clutch 90. The pressing member 91 is formed in the normal portion 91a rotatably mounted to the outer ring 90a of the roller clutch 90 and protrudes in the radial direction on the outer circumferential side of the ordinary portion 91a at intervals in the circumferential direction.

The interlock mechanism 89 operates in conjunction with the operation of the clutch switching mechanism 8, and when the clutch mechanism 7 is switched to the clutch off state by the clutch switching mechanism 8, the interlocking mechanism 89 contacts the oscillating tooth detent 82. In this way, the swinging detent 82 is separated from the ratchet 81 and moved to a release position where the pressing by the pressing mechanism 88 is possible. As a result, the motor 4 is brought into the reverse rotation permit state. In addition, when the motor 4 reverses rotation in the state, the interlock mechanism 89 is pressed by the pressing mechanism 88 to move to the stop position where the pressing is impossible. When moving to the locked position, the swinging tooth detent 82 is locked to the ratchet 81 from the swinging tooth detent 82.

The front end of the first lever member 94 is locked to the front end of the third protruding portion 56c of the clutch cam 51 constituting the clutch switching mechanism 8 so as to be rotatable and to move a predetermined distance. Thereby, while the rotation of the clutch cam 51 is transmitted to the 1st clutch return mechanism 11, the return operation of the 1st clutch return mechanism 11 is transmitted to the clutch cam 51, and a clutch switching mechanism ( 8) can be operated.

The second lever member 95 is a member whose proximal end is rotatably mounted to the chamfer 93b on the side plate 16 side of the connecting shaft 93. The tip end of the second lever member 95 is locked to the base end of the advancing and retracting member 96 so as to be able to move a predetermined distance. Thereby, the retraction member 96 moves forward and backward in conjunction with the operation of the clutch switching mechanism 8, and the clutch switching mechanism 8 operates in the clutch-off direction by the retraction operation of the retraction member 96. .

The advancing and retracting member 96 is guided by the pair of guides 27a and 27b formed in the bulge 27 so as to be linearly movable toward the oscillating tooth detent 82 and the pressing member 91. The retracting member 96 is a plate-like member in which the second lever member 95 is rotatably connected to the proximal end and movable in a predetermined range. The advancing and retracting member 96 is divided by the oscillating tooth detent 82 and extended to contact the lower surface of the oscillating tooth detent 82 and the pressing member 91 from the source of the first contact portion 96a. The tip has a second contact portion 96b that is bent toward (). The retracting member 96 allows the second contact portion 96b to be pressed by the pressing member 91, and the first contact portion 96a presses the swinging tooth detent 82 to swing to the reverse rotation permitting position. The release position (shown in FIG. 11) and the first contact portion 96a are movable from the swinging tooth detent 82 and the locking position (shown in FIG. 10), which is not pressurized by the press member 91. . 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 rock and the advancing member 96 advances to the release position and the motor When pressed by the pressing member 91 by the reverse rotation of (4), it retracts to a locked position. Thereby, the clutch cam 51 rotates to the clutch on direction via the 2nd and 1st lever members 95 and 94, and the clutch operating lever 50 returns to a clutch on position, and the clutch mechanism 7 ) Becomes 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 in accordance with the rotation of the file winding direction of the handle 2a to return the clutch mechanism 7 to the clutch on state. In addition, the clutch cam 51 returns the clutch operation lever 50 from the clutch off position to the clutch on position. The second clutch return mechanism 12 divides and presses the engaging member 61 (described above), the ratchet wheel 62 having the ratchet teeth 62a formed on the outer circumference, and the engaging member 61 toward the engaged position and the non-engaged position. It is comprised by the 2nd toggle spring 66 to be made.

It has the projection 61a and the 2nd projection 61b extended to the left of FIG. 6 of the 1st projection 61a.

The 1st protrusion 61a is bent toward the outer side of the ratchet wheel 62, and the 2nd protrusion 61b is bent in the reverse side to the fixing frame 20 side. The fixed frame 20 is formed with guide traps 20a having a deformed trapezoidal shape that engage with the second protrusions 61b. The guide protrusion 20a engages with the second protrusion 61b and is provided to control the swinging direction of the engagement member 61.

When the engaging member 61 is disposed in the engaged position, the first projection 61a is located on the inner circumferential side of the ratchet wheel 62 so as to be able to engage the ratchet teeth 62a, so that the engaging member 61 is not in the engaged position. When arrange | positioned, the 1st protrusion 61a is located in the position slightly separated from the outer periphery of the ratchet wheel 62. As shown in FIG. This engagement member 61 is arrange | positioned in front of or above the shaft center of the ratchet wheel 62. As shown in FIG. For this reason, compared with the conventional example arrange | positioned behind the ratchet wheel 62, the space at the back side of the ratchet wheel 62 becomes small. The first projection 61a of the engagement member 61 is pulled by the ratchet teeth 62a to rotate from the engagement position (shown in FIG. 7) to the non-engagement position (shown in FIG. 6).

In addition, since it is the same structure as the conventionally well-known electric reel 1 about a level wind mechanism and a casting control mechanism, description is abbreviate | omitted.

[Clutch switching action]

Next, the clutch switching operation of the electric reel 1 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 in a clutch on state.

In the case of putting the gear, the clutch operating lever 50 is swung to the clutch off position (shown in FIG. 7). When the clutch operating 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 in the counterclockwise direction in FIG. As a result, the clutch yoke 52 is caught by the cam protrusions 57a and 57b of the clutch cam 51, and the clutch yoke 52 moves outward in the pinion gear axial direction. Since the clutch yoke 52 is engaged with the reduced portion 35c of the pinion gear 35, the pinion gear 35 also moves in the same direction as the clutch yoke 52 moves outward. In this state, the engagement between the engagement concave portion 35a of the pinion gear 35 and the engagement convex portion 46a of the second carrier 46 is released, and the clutch is turned off. In this clutch off state, the spool 3 is freely rotatable. As a result, the fishing line is discharged from the spool 3 by the weight of the gear.

In the jogging mode, for example, when the discharge amount exceeds a predetermined amount (for example, the depth indication of the gear is 6 m), or the rotation speed of the spool 3 exceeds the predetermined speed, the motor 4 Rotate in the winding direction. In this clutch off state, since the second carrier 46 rotates, the planetary gear mechanism 40 does not decelerate even when the motor 4 is rotated forward. However, the planetary gear mechanism 40 and the spool 3 between the planetary gear mechanism 40 are rotated. The friction is reduced, so that the spool 3 rotates in the Joule discharge direction at a higher speed than in the free rotation state.

In addition, when the clutch cam 51 rotates to the clutch off position, the engaging member 61 of the second clutch return mechanism 12 is guided to the guide protrusion 20a to swing in the clockwise direction, and when the dead point exceeds the dead point, The two toggle springs 66 are pressed into the ratchet wheel 62. As a result, the engagement member 61 is arrange | positioned at the engagement position latched by the ratchet tooth 62a.

In addition, when the clutch cam 51 rotates to the clutch off position, the retraction member 96 of the interlocking mechanism 89 of the first clutch return mechanism 11 is released from the locking position (shown in FIG. 10) (FIG. 11). To the city). When the retracting member 96 advances to the release position, the first contact portion 96a contacts the swinging tooth detent 82 of the second one-way clutch 10 to move the swinging tooth detent 82 in the reverse rotation prohibition position. It swings to the reverse rotation permission position (shown in FIG. 11) from (shown in FIG. As a result, the motor 4 is in a state capable of reverse rotation. Moreover, when the advancing member 96 advances to a release position, the 2nd contact part 96b is arrange | positioned in the position which the protrusion part 91b of the press member 91 can press.

When the gear is placed on a predetermined fish breeding layer, the motor 4 is rotated in reverse, the handle 2a is rotated in the file winding direction, or the clutch operating lever 50 is swung in the clutch on position to spool ( Stop the joule discharge of 3). In the automatic fish breeding layer stop mode, the discharge of the spool 3 automatically stops at the fish breeding layer position by the reverse rotation of the motor 4.

When the motor 4 is reversely rotated, the first clutch return mechanism 11 returns to the clutch on state. When the motor 4 is rotated in reverse, as shown in FIG. 11, the pressing member 91 rotates in reverse (rotation in clockwise direction in FIG. 11), and one of the three protrusions 91b moves forward and backward. 2nd contact part 96b of the () is pressed, and the advancing member 96 is retracted from a release position toward a latching 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. 7. 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 member 96 also returns to the locked position. Moreover, when the clutch cam 51 rotates clockwise to the clutch on position, the clutch yoke 52 caught by the cam protrusions 57a and 57b of the clutch cam 51 withdraws from the cam protrusions 57a and 57b. The coil spring 54 moves inward in the spool shaft direction. As a result, the pinion gear 35 also moves inward in the spool axis direction and is disposed at the clutch on position. In addition, when the clutch cam 51 rotates clockwise in FIG. 7, the clutch operation lever 50 held by the first protrusion 56a also swings to the clutch on position. Thereby, the clutch mechanism 7 can be made into the clutch on state from the clutch off state, without operating the clutch operation lever 50. FIG. Also, when the retraction member 96 returns to the locked position, the swinging detent 82 pushed by the torsion coil spring 83 returns to the reverse rotation prohibition position, and the first one-way clutch 9 reversely rotates. In the prohibition state, reverse rotation of the motor 4 is prohibited.

At the time of reverse rotation of this motor 4, the pressing member 91 mounted on the mechanism mounting shaft 75 via the roller clutch 90 collides with the second contact portion 96b of the retraction member 96 and presses it. do. At this time, an impact acts on the pressing member 91, and the torque thereby acts on the serration 30a of the fixed portion between the mechanism mounting shaft 75 and the output shaft 30. Since this part is 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 fear of idling at that part. Thus, in the present embodiment, the motor 4 is controlled to a duty ratio that gradually increases from the second duty ratio D2 shown in FIG. 21 to the third duty ratio D3 as described above, and is applied to the motor 4. The voltage to be increased is gradually raised to the voltage at which the advance / remove member 96 can be pressed. As a result, the torque when the pressing member 91 collides with the retreating member 96 at the start of reverse rotation becomes small, and the output shaft 30 such as the mechanism mounting shaft 75 on which the pressing member 91 is mounted is reduced. The mounted driving parts become difficult to idle.

When the handle 2a is rotated in the file winding direction, the second clutch return mechanism 12 returns to the clutch on state. When the handle 2a is rotated in the file winding direction, the handle shaft 33 rotates clockwise in FIG. 7. According to this, the ratchet wheel 62 fixed to the handle shaft 33 so as not to rotate also rotates clockwise. When the ratchet wheel 62 rotates clockwise, the first projection 61a of the engagement member is caught by the ratchet tooth 62a and the engagement member 61 is pulled out.

When the engagement member 61 is pulled out, the engagement member 61 is guided to the guide protrusion 20a and oscillated in the counterclockwise direction, and the engagement member 61 is moved at a time when the dead point of the second toggle spring 66 is exceeded. It is pressed outward of the ratchet wheel 62. The engagement member 61 swings outward toward the non-engagement position not engaged with the ratchet wheel 62.

In addition, when the engagement member 61 is pulled out, the clutch cam 51 connected to the engagement 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 made into the clutch on state from the clutch off state, without operating the clutch operation lever 50. FIG.

The engaging member 61 of the second clutch return mechanism 12 is disposed above and behind the handle shaft 33. The upper front position of this handle shaft 33 becomes an empty space, when the counter 5 is provided. If the engagement member 61 is provided in this empty space, expansion of the reel main body can be made small compared with the structure which arrange | positions an engagement member to the back or the bottom of a handle shaft like a conventional thing.

In addition, even when the clutch operating lever 50 is operated from the clutch off position to the clutch on position, the first and second clutch return mechanisms 11 and 12 return the engaging member 96 to the locked position and the engaging member ( It goes without saying that 61 returns to the non-engaged position.

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

At the time of manual winding, rotation of the handle 2a in the file winding direction (Fig. 6 clockwise rotation) is performed by the handle shaft 33, the main gear 34, the pinion gear 35 and the planetary gear mechanism 40. Through this, it is transmitted to the spool 3 at an increased speed. At this time, the reverse rotation of the motor 4 (counterclockwise rotation as viewed from the right in FIG. 4) is prohibited by the second one-way clutch 10. For this reason, the 1st sun gear 41 of the planet gear mechanism 40 does not rotate reversely, and since the 1st sun gear 41 rotates in the file winding direction (rotation clockwise from the right of FIG. The rotation is transmitted to the internal gear 3d through the two planetary gears 44, the first carrier, and the first planetary gear 43, so that the spool 3 is driven in the file winding direction at an increased speed.

In addition, at the time of motor drive, rotation of the motor 4 which rotates forward (clockwise rotation from the right of FIG. 4) is transmitted to the spool 3 via the planetary gear mechanism 40. At this time, since the rotation (rotation in the counterclockwise direction as seen from the right in FIG. 4) of the handle shaft 33 is prohibited by the first one-way clutch 9, the second carrier 46 is reversed. Rotation (clockwise rotation from the right of FIG. 4) is prohibited. For this reason, the rotation of the reduced 2nd sun gear 42 is transmitted to the internal gear 3d through the 2nd planetary gear 44, and the spool 3 is decelerated-driven.

In addition, as shown in FIG. 12, when the motor 4 rotates forward (rotation counterclockwise in FIG. 12) in the clutch-on state, the silent cam 85 of the toothed detent control mechanism 84 moves in the same direction. It rotates and stops the tooth detent part 82a of the oscillation tooth detent 82 by the rotation control part 86 in the position which the press part 85a presses. At this time, since the silent cam 85 is only frictionally engaged with the mechanism mounting shaft 75, the motor 4 rotates as it is. As a result, the swinging tooth stop 82 is pushed by the pressing portion 85a to swing to the reverse rotation permitting position to the position crossing the protrusion 81a of the ratchet 81, and the ratchet 81 stops swinging. It is not in contact with the iron 82. For this reason, when the motor 4 rotates forward, the click sound by the swinging detent 82 of the 1st one-way clutch 9 repeats contact with the ratchet 81 will not generate | occur | produce. Can be planned.

When the motor 4 rotates in reverse, the silent cam 85 also rotates in the same direction, and as shown in FIG. 10, the pressing portion 85a is moved from the tooth detent portion 82a by the rotation restricting portion 86. It stops at the fall position, and the oscillation tooth detent 82 is pressed by the torsion coil spring 83, and returns to a reverse rotation prohibition position.

In addition, when the motor 4 rotates forward in the clutch-off state as in the line feed mode, the silent cam 85 also rotates in the same direction, so that the silence can be achieved. At this time, since the pressing member 91 is mounted on the mechanism mounting shaft 75 via the roller clutch 90 which transmits only the reverse rotation of the motor 4, the rotation of the mechanism mounting shaft 75 is performed by the pressing member ( 91) is not delivered. For this reason, even when the advancing member 96 is arranged so as to be in contact with the pressing member 91 in a clutch off state, the pressing member 91 does not press the advancing member 96, thereby causing malfunction It does not occur

[Operation of the Reel Control Unit]

Next, the specific control process performed by the reel control part 100 is demonstrated according to the control flowchart of FIG.

By connecting one end of the power cord 130 to the connector portion 14a of the electric reel 1, and connecting the alligator clip of the other end of the power cord 130 to the battery 136, the electric reel 1 When connected to this battery 136, initial setting is performed in step S1 of FIG. In the initial setting of step S1, as shown in FIG. 24, in step S121, the prohibition flag FP for prohibiting the drive of the motor 4 is set (on). Next, the flow advances to step S122 to perform motor control processing. In step S123, for example, other settings such as resetting the count value of the spool rotation speed and resetting various variables and flags are performed.

As shown in FIG. 25, the motor control process of step S122 starts with the prohibition flag FP set. In step S131, it is determined whether the step ST of the potentiometer 104 according to the output of the potentiometer 104 (that is, the swing angle of the adjustment lever 101) is zero. If step ST = 0, that is, when the adjustment lever 101 is in the stop position, the flow advances to step S136 to turn off the prohibition flag FP. When step ST> 0 (ST = 1 to 30), that is, when the adjustment lever 101 is in the swinging position, the process proceeds to step S132.

In step S132, it is determined whether step ST is larger than predetermined swing step SU. The predetermined swinging step SU is a step of determining according to the predetermined swinging angle of the adjustment lever 101. The predetermined swing angle range of the adjustment lever 101 is in the range of 5 degrees or more and 45 degrees or less, preferably in the range of 20 degrees or more and 40 degrees or less. For example, when the predetermined rotational angle of the adjustment lever 101 is 30 degrees, since the rotation angle range of the adjustment lever 101 is 140 degrees, the predetermined swinging step SU = [(30 degrees / 140 degrees) × 30 steps ] = [6.42 steps] = 7 steps. Here, when step ST> step SU, ie, step ST> 7 (ST = 8-30), it transfers to step S134 and step ST <= step SU, ie step When (ST) ≤ 7 (ST = 1 to 7), the process proceeds to step S133.

In step S133, the process starts with a state of ST ST ≤ 7 (ST = 1 to 7), and furthermore, the adjustment lever 101 is swung to the stop position to determine whether or not the step ST is zero. . When step ST = 0, the flow advances to step S135 to turn off the prohibition flag FP. When the step ST does not become 0, for example, the adjustment lever 101 is not rocked, rocked in the speed increasing direction, or rocked in the deceleration direction at a position where step ST> 0. When it returns to the main routine.

In step S134, it starts in the state where step ST> 7 (ST = 8-30), rocks the adjustment lever 101 more than step SA in a deceleration direction, and also speeds up the adjustment lever 101. It is judged whether or not the oscillation is more than step SB in the direction. Step SA is at least step SU, here at least 7 steps. In addition, step SB is one or more steps | paragraphs. In step S134, when step ST decreases step SA and> step SU, and after step SB increases, it progresses to step S136 and the prohibition flag FP is turned off. Specifically, when step ST = 10 steps, for example, step SA = 8 steps (> step SU = 7 steps) is oscillated in the deceleration direction, and further, step SB = 12 steps (≥ 1). However, by oscillating in the increasing direction, steps ST = 10 steps (step ST)-8 steps (step SA) + 12 steps (step SB) = 14 steps are obtained in this state. Since the prohibition flag FP is turned off, the drive in the 14th stage of the motor 4 becomes possible. In addition, the adjustment lever 101 is not oscillated after the step ST decreases the step SA and the step SU or the step SB after the step ST decreases the step SA and SU. When it increases, or when the adjustment lever 101 is not rocked, or only rocked in the speed increasing direction or the speed decreasing direction, it returns to the main routine.

In step S2 of FIG. 15, the power supply voltage PV detected by the power supply voltage sensor 103 is received. In step S3, it is determined whether 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 different power supply voltage from the lead acid battery is connected to the reel. When a battery having a high power supply voltage PV (for example, a lithium battery or a nickel hydride battery) is connected, the process shifts from step S3 to step S4 where the duty ratio D1, D2 and D3 are corrected according to the detected power supply voltage PV. Specifically, the first, second and third duty ratios D1, D2, and D3 are multiplied by the value (Vh1 / PV) obtained by dividing Vh1 (for example, 12) by the power supply voltage PV. Let it be 1, 2nd and 3rd duty ratio D1, D2, and D3. 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 the duty control is performed in the forward rotation (row winding direction). The first and second voltages V1 and V2 applied to the motor 4 hardly change. In addition, in this embodiment, the power supply voltage for determining the power supply is determined only once after the initial setting to which the power supply is connected. However, multiple determinations may be made after the power supply is connected.

Next, in step S5, display processing is performed. In the display process, various display processes such as depth display are performed. In step S6, it is determined whether any one of the operation key portions 99 or the adjustment lever 101 has been operated. In step S7, it is determined whether or not the spool 3 is rotating. This determination is judged by the output of the spool sensor 102. In step S8, a power supply voltage detection process (shown in FIG. 20) for monitoring a voltage abnormality is performed. In step S9, it is determined whether or not the depth data LX calculated by the output of the spool sensor 102 exceeds 6m. In step S10a, when the depth data LX is 6 m or less, it is determined whether the spool 3 has stopped for more than 6 seconds. In step S10b, it is determined whether the request to be transmitted to the sonar monitor 120 exists. In step S11, it is determined whether any one of the three lead wires 152a, 152b, 152c of the potentiometer 104 connected to the adjustment lever 101 is disconnected. This determination is made by the voltage output from the potentiometer 104 as mentioned above. In step S12, it is determined whether other commands or input have been made. When this determination is finished, the flow returns to step S5.

When the key input by the operation key part 99 or the adjustment lever 101 is made, it transfers to step S13 from step S6, and performs a key input process (shown in FIG. 16). When rotation of the spool 3 is detected, the flow advances 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 6m, the process proceeds from step S9 to step S15. In step S15, it is determined whether the stop time of the preparation in the depth data LX exceeds 6 second. If it exceeds 6 seconds, since it is considered that the preparation is stopped in the fish habitation layer, the flow advances to step S16 and sets the depth data LX to the fish habitation layer position M. FIG. When the water depth data LX is 6 m or less, when the spool 3 is stopped for more than 6 seconds, it is considered that the preparation is stopped at the power distribution. For this reason, it transfers from step S10a to step S17, and sets the depth data LX to distribution line length FB. If there is a transmission request, the flow proceeds from step S10b to step S18. In step S18, the sonar monitor 120 transmits the requested data. For example, the depth data LX and the item set on the reel side are transmitted to the sonar monitor 120. If it is determined that the lead wires 152a, 152b, and 152c of the potentiometer 104 are disconnected, the flow advances from step S11 to step S19, and the alarm display of the contents is, for example, the depth display of the depth display unit 98. In place of the depth display, the portion 98a displays, for example, the letters Err5, Err6, and Err7 in correspondence with the lead wires 152a, 152b, and 152c that were disconnected. If any other command or input is made, the process shifts from step S12 to step S20 to execute other processing.

In the key input process of step S13 of FIG. 15, as shown in FIG. 16, it is determined whether step ST operated by the adjustment lever 101 in step S21 is 0. FIG. When step ST is zero here, it transfers to step S22 and the motor 4 is stopped (off). In addition, if it is already stopped, it stops as it is. In step S23, it is determined whether the menu button MB has been operated. In step S24, it is determined whether the decision button DB has been operated. In step S25, it is determined whether the fast forward button HB has been operated. In step S26, another key operation is performed, for example, setting of the learning mode by operation of the memo button TB or operation of the menu button MB and the fast forward button HB for a predetermined time. Determine whether or not.

When step ST of the adjustment lever 101 is not 0, it transfers to step S27 from step S22. In step S27, it is determined whether the depth data LX is 0 or less. In this embodiment, the depth data LX is operated even when the adjustment lever 101 is operated in the state where the power distribution mode (the mode of automatically stopping the winding of the spool while the gear is easily recovered) is set in order to protect the fishing rod. If)) is 0 or less, it cannot be wound further. In addition, as described above, the delivery mode is automatically set when the spool 3 is in the stopped state for a predetermined time (for example, six seconds) when the depth data LX is 6 m or less. When the depth data LX is not equal to or less than zero, the flow advances to step S28 to execute the motor drive process (shown in FIG. 17). When the depth data LX is equal to or less than zero, the flow advances from step S27 to step S29. In step S29, it is determined whether it is in a power distribution mode. If it is not in the power distribution mode, the flow advances to step S28 to execute the motor drive process. In the power distribution mode, the flow advances to step S30, whereby the adjustment lever 101 moves two clicks within a predetermined time (for example, three seconds) toward step ST = 0, which is the swing start position (that is, three or more times different). Direction rocking operation) is judged. This special click operation enables driving in the direction of winding up the spool 3 in the power distribution mode and even when the depth data LX is equal to or less than zero. If it is judged that the click operation has been performed, the flow advances to step S28 to execute the motor drive process. If the click operation is not performed, the driving of the motor is prohibited, and therefore, the process proceeds to step S23 without any processing.

When the menu button MB is operated, the flow advances from step S23 to step S31, and the item of the character or fish habitat layer position displayed on the depth display section 98 is flickered and moved for each operation to select the item.

When the decision button DB is operated, the process proceeds from step S24 to step S32. In step S32, it is determined whether the decision button DB has been pressed for 3 seconds or more. If it is not pressed for a long time, the process proceeds 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 sonar monitor 120. If it is necessary to transmit, the process proceeds to step S35 to make a request for transmission of the item, and if unnecessary, skips step S35 and proceeds to step S25. On the other hand, when it determines with a long press, it transfers to step S36 from step S32. In step S36, the current depth data LX is set to 0 as the reference line length as a reference for the line length. After this, the subsequent depths are expressed by the depth of the data LX at the set position as 0 and the subsequent line lengths.

When the fast forward button HB is operated, the flow advances from step S25 to step S37. In step S37, it is determined whether the depth data LX is less than the distribution line length FB. When the depth data LX is equal to or larger than the distribution line length FB, the flow advances to step S38, where a prohibition flag FP for prohibiting the driving of the motor 4 set in the power supply voltage detection process (described later) is set ( It is determined whether or not it is on). When the prohibition flag FP is not set, the process proceeds to step S39, where the first duty ratio D1 is set to 95%, for example, to drive the motor 4 at the highest speed. When the depth data LX is less than the distribution line length FB, the flow advances to step S26 to invalidate the operation by the fast forward button HB. When other key input such as an operation to enter the memo button TB or the winding learning mode is performed, the process moves from step S26 to step S40 to perform key input processing according to the operation, and returns to the main routine.

In the motor drive process by the adjustment lever 101 of step S28 of FIG. 16, step ST is a rotation speed of the spool 3 (an example of the rotation speed of the motor 4) from 1 to 4 steps. By detecting and controlling the speed of the motor 4, the motor 4 is torque-controlled so that the tension acting on a fishing line may be constant from 5 to 30 steps. In the motor drive 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 processing ends and returns to the key input processing. If the prohibition flag FP is not set, the process proceeds to step S41b. In step S41b, it is determined whether the step ST by the swing angle of the adjustment lever 101 is any of 1-4 steps. In addition, this determination is made by the voltage of the signal output from the potentiometer 104. In step S42, it is determined whether step ST is any of 5-30 stages.

When step ST is 1-4 steps, it will transfer to step S43 from step S41b. In step S43, the speed V output from the spool sensor 102 is received. In step S44, it is determined whether the speed V of the spool 3 is less than the lower limit speed Vst1 according to step ST. In step S45, it is determined whether the speed V of the spool 3 exceeds the upper limit speed Vst2 in step ST. In addition, the step ST which performs speed control provided the lower limit speed Vst1 and the upper limit speed Vst2 for every step ST in the 1st-4th stage, and the speed is fluctuating between both speeds Vst1 and Vst2. In this case, the duty ratio does not change, and there is no occurrence of a woring in which the duty ratio fluctuates frequently, so that 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.

If the speed V is less than the lower limit speed Vst1, the flow advances from step S44 to step S46 to read the current first duty ratio D1. This first duty ratio D1 is stored in the storage unit 107 whenever the setting is changed. In addition, the maximum value DUst and the minimum value DLst are set for each step ST, and when it is initially set in each step ST, for example, the first duty ratio D1 = ((DUst) in the middle thereof. + DLst) / 2). In step S47, it is determined whether the present first duty ratio D1 exceeds the maximum value DUst of the set step. If exceeded, the process proceeds to step S48 where the maximum value DUst is set in the first duty ratio D1. If it is not exceeded, the process proceeds from step S47 to step S49, and the first duty ratio D1 is increased by only a predetermined increment DI (for example, 1%) to move to step S45. In addition, the maximum value DUst of the highest stage (ST = 4) is set to 85% or less. Therefore, the upper limit of the adjustment operation by the adjustment lever 101 is 85% in duty ratio.

When the speed V exceeds the upper limit speed Vst2, the process shifts from step S45 to step S50 to read the current first duty ratio D1. This first duty ratio D1 is also the same as in step S46. In step S51, it is determined whether the current 1st duty ratio D1 is less than the minimum value DLst of the set step. If it is less, the flow proceeds to step S52 and the minimum value DLst is set in the first duty ratio D1. If not, the process proceeds from step S51 to step S53, where the first duty ratio D1 is reduced by only a predetermined decrease (for example, 1%), and the process proceeds to step S42.

If step ST is 5 to 30 steps, the process proceeds from step S42 to step S54. In step S54, the first duty ratio D1 is set to the duty ratio Dst according to step ST. Thereby, when step ST is 5-30 steps | paragraphs, it is controlled so that the electric current which flows into the motor 4 may become large for every step, and the motor 4 is torque-controlled. The duty ratio Dst according to each step ST is a value at the winding diameter (for example, the spool body diameter) which is a reference to the step ST, and the duty ratio Dst is determined by the winding diameter as the winding diameter increases. It grows gradually in proportion to each other. As a result, the torque of the fishing line becomes large according to the winding diameter, and the tension of the fishing line in which the torque increases as the winding diameter becomes large becomes substantially constant. In addition, the maximum duty ratio at the highest stage DUst of the speed constant control (ST = 4) and the maximum duty ratio at the highest stage of the torque control (ST = 30) are set to 85% or less. Therefore, the upper limit of the adjustment operation by the adjustment lever 101 is 85% in duty ratio.

In each operation mode process of step S14 of FIG. 15, as shown in FIG. 18, it is determined in step S61 whether the rotation direction of the spool 3 is a Joule discharge direction. This determination is judged by whether or not the Hall element of one of the spool sensors 102 has pulsed first. If it is determined that the rotation direction of the spool 3 is the Joule discharge direction, the flow proceeds from step S61 to step S62. In step S62, each time the count value of the pulse output from the spool sensor 102 decreases, data showing the relationship between the depth of water stored in the reel control unit 100 and the count value is read out based on the count value. The depth data LX is calculated. This depth data LX is displayed by a large 7-segment character in the center part of the depth display part 98 by the display process of step S5. In step S63, the transmission request of this depth data LX is performed.

In step S64, it is determined whether or not it is in the line sending mode. In step S65, it is determined whether or not the fish habitat layer is stopped. In step S66, it is determined whether or not it is another mode. If it is not in another mode, it finishes processing each operation mode and returns to the main routine.

In the line sending mode, the flow advances from step S64 to step S67. In step S67, it is determined whether the water depth LX exceeds 6m. In the file feed mode, the motor 4 is not rotated forward from the beginning, but the discharge of the fishing line is waited until the depth at which the fishing line can be surely discharged. When the water depth data LX exceeds 6 m, the flow advances to step S68 to rotate the motor 4 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 Joule discharge direction at a higher speed. When the depth data LX is 6 m or less, the step S68 is skipped.

When it determines with a fish culture layer stop mode, it transfers to step S69 from step S65. In step S69, it is determined whether or not the obtained water depth data LX coincides with the fish habitat layer position M, that is, whether the preparation has reached the fish habitat layer. The fish habitat layer position is set by pressing the memo button TB when the preparation reaches the fish habitat layer, in addition to the automatic set by the stop above the predetermined time. When the preparation reaches the fish habitat layer position, the process proceeds from step S69 to step S70. In step S70, the buzzer 106 is sounded to indicate that the preparation is in the fish habitat. In step S71, the motor 4 is rotated in reverse for a predetermined time. At this time, as shown in FIG. 21, the duty ratio is gradually raised from the second duty ratio D2 to the third duty ratio D3, and the voltage applied to the motor 4 is gradually raised. As a result, excessive torque due to the impact on the mechanism mounting shaft 75 is less likely to act, and the mechanism mounting shaft 75 mounted on the output shaft 30 of the motor 4 becomes difficult to idle. By the reverse rotation of this motor 4, the clutch mechanism 7 is returned to the clutch-on state by the 1st clutch return mechanism 11 via the clutch switching mechanism 8 by the above-mentioned operation | movement. As a result, the rotation of the spool discharge direction stops. If the depth data LX does not reach the fish habitat layer position M, the steps S70 and S71 are skipped. If it judges that it is another mode, it transfers to step S72 from step S66 and performs another set mode process.

If it is determined that the rotation of the spool 3 is in the file winding direction, the process proceeds from step S61 to step S73. In step S73, whenever the count value of the spool sensor 102 increases, the data stored in the reel control unit 100 is read out to calculate the depth data LX. This depth is displayed in the display process of step S5. In step S74, as in step S63, a transmission request is output. In step S75, it is determined whether the auto attracting mode is set. This auto attracting mode can be set in the electric reel 1 or the sonar monitor 120. When this auto attracting mode is set, the pattern can be set according to the attracting width which is the range in which the auto attracting mode is performed and the interval at which the motor 4 is turned on / off.

When the attraction width is set, the attraction width SA is displayed on the sonar monitor 120 side at a position along the water depth as shown by hatching as shown in FIG. In addition, the sonar monitor 120 also displays information such as the position FL of the fish farm, the position FL, the seabed BL, etc., based on the fish habitat layer position TL and the depth data LX output from the fish group detector 140. . Moreover, in the menu screen on the sonar monitor 120 side, as shown in FIG. 23, various settings on the electric reel 1 side including auto attracting setting AS and attracting width SA can also be performed. . It is also possible to perform an operation by tempting from an arbitrary position by the operation of the attracting button 134.

In step S76, it is determined whether the power distribution mode is set. In step S77, it is determined whether or not the depth data LX is negative.

If it is determined that the auto attracting mode is set, the process proceeds from step S75 to step S78. In step S78, an auto attracting process (shown in FIG. 19) is executed. This auto attraction process performs the attraction operation of turning on / off the motor 4 in the range set by the attraction pattern set from the fish habitat layer position M. FIG. Specifically, in step S90 (FIG. 19), it is determined whether the water depth data LX is winding more than the attraction width SA from the fish habitat layer position M. FIG. If the gear is within the attraction width SA, the flow advances to step S91. In step S91, it is determined whether the variable N for setting the number of attraction is zero. When this variable N is 0, it is said that attracting is performed for the first time. When the variable N is zero, the process proceeds to step S92 and sets the variable N to one. If the variable N is not zero, this processing is skipped. In step S93, it is determined whether or not the depth data LX has reached the position LX = M-N × L for turning off the motor 4 in the attraction operation. Here, the variable L is a value which changes by the attraction pattern. When the gear reaches the attraction position, the flow advances to step S94 to stop the motor 4 for a predetermined time. In step S95, only one variable N is increased in order to arrange the gear at the next attraction position. If the preparation has passed the attracting width, the process proceeds to step S96, where the variable N is cleared to zero and the process returns to each mode operation. In addition, in this embodiment, at the time of auto attracting, the spool 3 is rotated in the file winding direction at the same interval and at the same stop time depending on the number of attraction. However, the attraction pattern is not limited to this, and the inequality interval and the variable stop time may be sufficient.

If it is determined that the power distribution mode is set, the process proceeds from step S76 to step S79. In step S79, it is determined whether or not the water depth coincides with the distribution stop position. If it is not wound up to the delivery stop position, the flow proceeds to step S77. When the delivery stop position is reached, the flow advances from step S79 to step S80. In step S80, the buzzer 106 is sounded to indicate that the gear is in the boat. In step S81, the motor 4 is turned off. Thereby, a fish is arrange | positioned in the position which is easy to catch when a fish is caught. As described above, this delivery stop position is set if the spool 3 is stopped for a predetermined time or longer at a depth of 6 m or less. When the water depth becomes less than zero, the flow advances from step S77 to step S82. In step S82, the buzzer 106 is sounded to inform that the wind is over. In step S83, the motor 4 is turned off and the flow returns to the main routine.

In the power supply voltage detection process in step S15 of FIG. 15, the power supply voltage PV is received in step S100 of FIG. 20. In step S101, it is judged whether the motor 4 is rotating by the electric current which flows into the motor 4, for example. If the motor 4 is not rotating, the flow proceeds to step S102. In step S102, it is determined whether the power supply voltage PV has exceeded the allowable maximum voltage Vh2 (for example, 18 volts). If the power supply voltage PV exceeds the allowable maximum voltage Vh2, the flow proceeds from step S102 to step S103. In step S103, it is determined whether or not the timer T1 which measures the time which exceeds the permissible maximum voltage Vh2 is already set. By this timer T1, for example, when the common power supply is used by the some electric reel 1 in boat fishing, the voltage rise by an instantaneous inrush voltage can be excluded. If the timer T1 has not yet been set, the process advances to step S104 to set the timer T1. The value of the timer T1 is preferably in the range of 0.1 second to 1 second, for example. If it is in this range, even if a voltage rise continues, for example, damage to an electrical device will become less likely to occur. If the timer T1 is already set, step S104 is skipped. In step S105, the timer T1 determines whether the time has expired, that is, whether the power supply voltage PV continues to exceed the allowable maximum voltage Vh2 for the time T1. If the power supply voltage PV continues to exceed the allowable maximum voltage Vh2 for the time T1, the flow advances to step S106 to replace the depth indication on the depth display portion 98a of the depth display portion 98. For example, display the character of Err1. In step S107, the operation by the adjustment lever 101 or the fast forward button HB for the motor 4 is then invalidated until the power supply voltage falls below the allowable maximum voltage Vh2 or less. A prohibition flag FP is set (on) to prohibit driving of 4). In step S108, the timer T1 is reset, and the flow advances 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. As a result, it is judged whether or not the prohibition state is set due to excess voltage. If the prohibition flag FP is set, the process proceeds to step S110, the prohibition flag FP is reset (off), and the process proceeds to step S111. That is, in the motor driving prohibition state, when the power supply voltage PV becomes lower than the allowable maximum voltage Vh2, the motor driving prohibition is released.

In step S111, it is determined whether or not the power supply voltage PV has fallen below the allowable minimum voltage Vm (for example, 9 volts). When the power supply voltage PV is equal to or higher than the allowable minimum voltage, the control returns to the main routine. When the power supply voltage PV falls below the allowable minimum voltage Vm, the flow proceeds from step S111 to step S112. In step S112, it is determined whether or not the timer T2 which measures the time below the permissible minimum voltage Vm is already set. By this timer T2, the instantaneous voltage drop by the increase of a load can be excluded, for example. If the timer T2 has not yet been set, the process advances to step S113 to set the timer T2. As for the value of this timer T2, the range of 0.1 to 1 second is preferable, for example. Within this range, instantaneous voltage drops can be reliably ruled out. If the timer T2 has already been set, step S113 is skipped. In step S114, it is determined whether the timer T2 has timed out, that is, whether or not the power supply voltage PV continues to fall below the allowable minimum voltage Vm for the time T2. If the power supply voltage PV continues to fall below the allowable minimum voltage Vh2 for a period of time T2, the flow advances to step S115 to, for example, cause the power supply graphic 98c of the depth display unit 98 to blink. . In step S116, the timer T2 is reset to return to the main routine.

As described above, in the electric reel 1, the interlock mechanism 89 is operated by the pressing mechanism 88 only when the interlock mechanism 89 is operated by the reverse rotation of the motor 4 to return to the clutch on state. ), The pressing mechanism 88 is separated, so that the motor 4 and the interlock mechanism 89 are not always interlocked. For this reason, when the clutch switching mechanism 8 is manually operated and the clutch mechanism 7 is switched from the clutch off state to the clutch on state, the motor 4 does not rotate, and manual return operation is easily performed. .

In addition, when the motor 4 rotates forward, the toothed detent control mechanism 84 swings to the position where the oscillating toothed stop 82 intersects the ratchet 81. The oscillation tooth detent 82 for rotation prevention does not vibrate, and can aim at a quiet sound.

In addition, since the roller clutch 90 is installed between the pressing member 91 and the output shaft 30 of the pressing mechanism 88 to prevent the forward rotation of the output shaft 30 from being transmitted to the pressing member 91, At this time, even if the pressing member 91 contacts the interlocking mechanism 89, it will not be pressed, and a line feed mode can be performed smoothly.

Furthermore, since the voltage applied to the motor 4 is gradually raised from the first voltage V1 to the second voltage V2 at the time of the clutch return operation due to the reverse rotation of the motor 4, from the time of starting rotation When the switching operation is started, no shock torque load is applied, and excessive force is not applied to the mechanism mounting shaft 75 fixed to the output shaft 30 of the motor 4, thereby preventing idling of the mechanism mounting shaft 75. can do.

In addition, when the power supply 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. Therefore, each duty ratio becomes a smaller value than before the correction, so that even if the power supply voltage rises, the rotation state of each set end of the motor 4 at the forward rotation and the rotation state at the reverse rotation can be kept as constant as possible. In addition, since the power supply voltage is detected immediately after the power supply, it is possible to quickly recognize that another type of power supply is connected by comparison between the detected power supply voltage and the predetermined voltage.

In addition, the motor 4 can be driven in the direction of winding in the string direction even if the power distribution mode is set by a special operation that is difficult to malfunction such as a click operation to the swing start position within the predetermined time of the adjustment lever 101. . For this reason, it becomes possible to rotate the spool 3 to the side which winds up from a reference line length, preventing damage to a repair by a misoperation.

Furthermore, since the abnormality of the power supply voltage is judged by the power supply voltage when the motor 4 is not rotating, the rotation of the motor 4 does not stop by the abnormality of the power supply in use. In addition, since the judgment about the power supply voltage is always performed when the motor 4 is not rotating, damage due to an abnormality of the power supply voltage in use can be prevented.

Furthermore, in the lower stages up to the first M stages (for example, four stages) of the N stages, since the motor is speed-controlled so as to be the detected speed at the target speed set to increase the speed for each stage, The motor is controlled at the target speed accordingly. The motor is also torque controlled at higher stages (e.g. 5 to 30 gears). For this reason, in the low stage, even if a load is large, rotation of a motor becomes difficult to stop, and even if a load is small, a motor becomes difficult to rotate at high speed. Therefore, the rotation of the motor is stabilized at low stages.

In addition, for example, the power cord 130 is disconnected from the connector portion 14a of the electric reel 1, or the alligator clip of the power cord 130 is disconnected from the battery 136. After stopping, when the power cord 130 is connected to the electric reel 1 or the battery 136 and the motor 4 is restarted, the adjustment lever 101 is moved in the deceleration direction by a predetermined swing step (SU) or more. After performing only the swing operation SA, the motor 4 can be driven by swinging only the step SB in the speed increasing direction. Here, since the motor 4 can be restarted without rocking the adjustment lever 101 to the stop position (step ST = 0) as in the prior art, adjustment when restarting the motor 4 is performed. The operability of the lever 101 can be improved.

<Other Embodiments>

(a) In the above embodiment, open loop control is performed in which the torque control from the 5th stage to the 30th stage is performed at a constant duty ratio for each step, thereby simplifying the control and preventing chattering. However, the present invention is not limited to this, and as shown in Fig. 26, a torque sensor 109 for detecting the torque of the motor is provided, and the motor (by the feedback control) is controlled so that the detected torque becomes the target torque set for each step. 4) may be torque controlled. In addition, the torque sensor 109 may use a current detecting means for detecting a current flowing in the motor 4, and a torque sensor is installed on an axis that rotates in conjunction with a motor such as a shaft of the motor to detect torque. It is okay. Hereinafter, the motor drive process of another embodiment is demonstrated based on FIG. In FIG. 27, since the process similar to the Example shown in FIG. 17 is performed from step S41a to step S53, description is abbreviate | omitted.

If step ST is 5 to 30 steps, the process proceeds from step S42 to step S143. In step S143, the torque T of the motor 4 is taken in. Here, the torque T is detected based on the current value flowing in the motor 4. In step S144, it is determined whether the torque T of the motor 4 is less than the lower limit J torque Tst1 in step ST. In step S145, it is determined whether the torque T of the motor 4 exceeds the upper limit J torque Tst2 in step ST. In addition, the step ST performing torque control has the lower limit torque Tst1 and the upper limit torque Tst2 for each step ST in 5 to 30 steps, when the torque is fluctuating between both torques Tst1 and Tst2. This is because the duty ratio does not change, and there is no occurrence of a woring in which the duty ratio varies frequently, so that the feedback control is stabilized. The upper limit torque Tst2 and the lower limit torque Tst1 are set within ± 10% of the target torque Tst, for example.

If the torque T is less than the lower limit torque Tst1, the process shifts from step S144 to step S146 to read the current fourth duty ratio D4. This fourth duty ratio D4 is stored in the storage unit 107 whenever the setting is changed. In addition, the maximum value DUst and the minimum value DLst are set for each step ST, and when it is first set in each step ST, for example, the fourth duty ratio D4 = ((Dust) in the middle thereof. + DLst) / 2). In step S147, it is determined whether the present first duty ratio D1 exceeds the maximum value DUst of the set step. If it exceeds, step S148 is reached in which the maximum value DUst is set in the fourth duty ratio D4. If it is not exceeded, the process proceeds from step S147 to step S149, and the fourth duty ratio D4 is increased by only a predetermined increment DI (for example, 1%), and the process proceeds to step S145. In addition, the maximum value DUst of the highest stage (ST = 30) is set to 85% or less. Therefore, the upper limit of the adjustment operation by the adjustment lever 101 is 85% in duty ratio.

If the torque T exceeds the upper limit torque Tst2, the flow advances from step S145 to step S150 to read the current fourth duty ratio D4. This fourth duty ratio D4 is also the same as in step S146. In step S151, it is determined whether or not the current fourth duty ratio D4 is lower than the minimum value DLst of the set step. If it is less, the flow advances to step S152 to set the minimum value DLst in the fourth duty ratio D4. If not, the flow proceeds from step S151 to step S153, where the fourth duty ratio D4 is reduced to only a predetermined decrease DI (for example, 1%), and the flow advances to step S42. In addition, the lower limit torque Tst1 and the upper limit torque Tst2 set for every step are the values in the winding diameter (for example, the spool trunk diameter) which are the reference | standard with respect to the step ST, and these values are winding when the winding diameter becomes large. It grows gradually in proportion to the diameter. As a result, the torque is increased in accordance with the winding diameter, and the tension of the fishing line in which the torque increases as the winding diameter becomes large becomes substantially constant.

In such torque control, since the feedback control is performed so that the detected torque becomes the set torque, the accuracy in the torque control is improved.

(b) In the above embodiment, the speed control is performed from the first stage to the fourth stage, and the torque control is performed from the fifth stage to the 30 stage, but the step of changing from the overall step and the speed control to the torque control is limited to the above embodiment. It doesn't work.

(c) In the above embodiment, an electric reel having a counter has been described as an example, but the present invention can be applied to an electric reel having no counter.

(d) Although the potentiometer is used as the swing position detecting means in the above embodiment, the swing position detecting means is not limited to the potentiometer and may be any type as long as it can detect the swing position of the adjustment lever.

(e) In the above embodiment, the lower limit value Vst1 (Tst1) and the upper limit value Vst2 (Tst2) for each step ST are determined during feedback control, and the duty ratio is changed when there is a speed or torque therebetween. Wowing is prevented by preventing the feedback, but feedback control may be performed at a predetermined target value Vst (Tst) for each step ST.

(f) In the above embodiment, the motor driving process by the adjustment lever 101 is performed even in the click operation of the adjustment lever 101 in FIG. 16. However, in the click operation, for example, step ST is performed. The motor 4 may be driven at a fixed speed of any one of the low speed sides of 1 to 4. In this case, if it is determined in step S30 of FIG. 16 that the click operation is performed, for example, the first duty ratio D1 may be set to a value of step ST = 1.

(g) In the above embodiment, the adjustment lever 101 is limited so that the maximum duty ratio is 85% or less, but it is not necessary to limit it.

(h) In the above embodiment, the distribution line length is set when the spool is stopped for a predetermined time when the water position data LX is less than 6 m in the distribution position, but the distribution line length can be set by the operation member. It's okay. In the above embodiment, the reference line length is set by pressing and holding the decision button DB. However, the reference line length may be set automatically under any condition as in the case of the distribution line length.

(i) In the above embodiment, it was possible to wind up from the O-set to the minus side by the click operation of the adjustment lever 101 when the distribution string length was set, regardless of whether the distribution string length was set or not. It is also possible to make it possible to wind up to the negative side by a special operation.

(j) Although the predetermined rotational angle of the adjustment lever 101 was 30 degrees in the said embodiment, it is not limited to this, It can set to arbitrary angles. According to this, the predetermined swing stage SU can also be set to any stage. For example, when the swing angle range of the adjustment lever 101 is 30 degrees, the previous step is 30 steps. When the swing angle is 5 degrees or more and 45 degrees or less, the predetermined swing step SU is in the range of 2 steps or more and 10 steps or less. Becomes

(k) In the above embodiment, the number and motor control process were detecting the step ST of the potentiometer 104 outputted according to the swing of the adjustment lever 101, but to detect the swing angle of the adjustment lever 101 directly. You may.

(l) Although the adjustment lever 101 was a lever member which can rock in the front-back direction in the said embodiment, it is not limited to this, For example, you may rock in the left-right direction.

According to the present invention, in the low stages up to the first M stage of the N stages, since the motor is speed-controlled so that the detected speed becomes the target speed set to increase the speed in each stage, the target speed according to each stage in the low stage is obtained. The motor is controlled. Also at high stages the motor is torque controlled. For this reason, in the low stage, even if a load is large, it becomes difficult to stop rotation of a motor, and even if a load is small, a motor becomes difficult to rotate at high speed. Therefore, the rotation of the motor is stabilized at low stages.
