TECHNICAL FIELD This invention relates to the motor control apparatus of an electric reel which drives a motor control apparatus, especially the spool rotatably attached to a reel main body by a motor.

Electric reels are often used for boat fishing and are convenient for catching fishing targets that live in relatively deep water. In recent years, it is often used for a relatively shallow fishing object. As a motorized reel of this kind, a motorized reel capable of rotating a spool in a file winding direction by a motor and rotating the motor in a multistage rotational state is known. Such electric reels are supplied with electric power to a plurality of electric reels from a power source mounted on a fishing boat, or each power source or electric power is supplied by carrying a dedicated electric power source. Since various power sources may be used in the electric reel in this way, the electric reel which has a function which monitors a power supply voltage is known (refer patent document 1). In the conventional electric reel, the change of the power supply voltage is constantly monitored during use of the electric reel, and the driving of the motor is stopped when an abnormal power supply voltage is detected.                         

[Patent Document 1] Japanese Patent Application Laid-Open No. 10-286048

In the conventional electric reel having a power supply monitoring function, the power supply voltage is constantly monitored during use, so that an abnormality in the power supply voltage can be dealt with promptly. However, when a plurality of motorized reels share the ship's inboard power, there is a fear that the motor may stop by detecting the inrush voltage when an inrush voltage occurs when another motorized reel is driven. In particular, if the motor stops when a fish is caught and caught, the fish caught may be missed. In order to prevent this, it is conceivable to monitor the power supply voltage only when the power supply is turned on. However, if the power supply voltage is detected only when the power supply is turned on, an abnormal overvoltage of the inboard power supply being used may damage electric equipment such as a motor used in the electric reel.

An object of the present invention is to provide a motor control apparatus for an electric reel connected to an external power source, so that damage to the device due to an abnormal power supply voltage in use can be prevented without stopping the motor.

A motor control apparatus for an electric reel according to the first aspect of the present invention provides a motor control apparatus for an electric reel that drives a spool rotatably mounted to a reel main body with a motor, the power supply voltage detecting means, the motor rotation detecting means, and the first The determination means, the first notification means, and the motor control means are provided. The power supply voltage detecting means is means for detecting a power supply voltage supplied to the motor. The motor rotation detection means is a means for detecting the presence or absence of rotation of the motor. The first judging means judges whether or not the power supply voltage detected by the power supply voltage detecting means has exceeded the first voltage when the motor is not rotating, and determines whether the power supply voltage has exceeded the first voltage when the motor is rotating. It is a means not to judge whether or not. The first notification means is means for notifying the contents of the excess of the power supply voltage when the determining means determines that the power supply voltage is exceeding the first voltage. The motor control means is a means for controlling the rotational state of the motor, and means for prohibiting the driving of the motor until the power supply voltage becomes less than or equal to the first voltage after the first notification means notifies the contents of excess.

In this motor control apparatus, when the power supply voltage detected when the motor is not rotating exceeds the first voltage, the notification that the power supply voltage is exceeded is issued. And while the power supply voltage exceeds the first voltage, driving of the motor is prohibited. When the power supply voltage is less than or equal to the first voltage, the motor can be rotated. Here, since the abnormality of the power supply voltage is judged by the power supply voltage when the motor is not rotating, the rotation of the motor does not stop due to the power supply abnormality in use. In addition, since the judgment on the power supply voltage is always performed when the motor is not rotating, it is possible to prevent the device from being damaged due to abnormal supply voltage.

In the motor control apparatus for an electric reel according to the second aspect of the invention, in the apparatus according to the first aspect, the first determination means includes a detection result of the power supply voltage detecting means that exceeds the first voltage and the state is maintained for the first predetermined time or more. In this case, it is determined that the power supply voltage exceeds the first voltage. In this case, the driving of the motor is not immediately prohibited even if the power supply voltage exceeds the first voltage when the motor is not rotating, but it is determined that the power supply voltage exceeds the first voltage over time. A voltage rise will not interfere with the operation of the motor.

The motor control apparatus for an electric reel according to the third aspect of the invention is the apparatus according to the first aspect, wherein the state of the detection of the power supply voltage detecting means is lower than or equal to the second voltage lower than the first voltage and the state is maintained for the second predetermined time or more. Second judging means for judging whether or not and a second judging means for notifying the contents of the drop in the power supply voltage if the second judging means judges that the state has continued below the second voltage lower than the first voltage and lasted more than a second predetermined time. It further comprises two notification means. In this case, it is possible to respond quickly to the voltage drop due to the consumption of the power supply. The determination by the second judging means may be performed irrespective of the rotation of the motor, or may be performed when the motor is rotating or when the motor is not rotating.

The motor control apparatus for an electric reel according to the fourth aspect of the invention further includes a rotational state operating means for operating the rotation of the motor in a plurality of stages of rotation, in the apparatus according to any one of the first to third aspects of the invention. The motor control means controls the motor to be in the operated rotation state. In this case, by operating the rotation state operating means, the rotation state can be changed according to the fish or the fishing method of a fishing object.

The motor control apparatus for an electric reel according to the fifth aspect is the apparatus according to any one of the first to third aspects, wherein the electric reel has a depth display portion capable of displaying various depths, and the first notification means By displaying a letter indicating the content, the content of excess of the power supply voltage is notified. In this case, since the excess of the power supply voltage is displayed on the depth display portion, the angler can easily recognize the content.

The motor control apparatus for an electric reel according to the sixth aspect of the invention is the apparatus according to the third aspect, wherein the electric reel has a depth display portion capable of displaying a power supply diagram showing states of various depths and power supply voltages, and the second notification means provides a power supply. By displaying the figure, the contents of the drop in power supply voltage are notified. In this case, the fall of the power supply voltage can be recognized at the moment.

The motor control apparatus for an electric reel according to the seventh aspect is the apparatus according to the fourth aspect, further comprising motor driving means for driving the motor with pulse width modulated electric power, wherein the motor control means operates the rotational state of the motor driving means. The first duty ratio is corrected according to the power supply voltage when the detected power supply voltage exceeds the third voltage, while controlling based on the first duty ratio according to the rotational state set by the means.

In this motor control apparatus, when the power supply voltage exceeds the third voltage, the first duty ratio according to the rotation state in which the motor drive means is operated by the rotation state operation means is corrected according to the detected power supply voltage. For example, the first duty ratio is corrected by a ratio between the detected power supply voltage and the first voltage. When the rotational state of the motor is set by the rotational state operating means, the motor drive means is controlled based on the first duty ratio or the corrected first duty ratio. Here, when the power supply voltage exceeds the first voltage, the first duty ratio is corrected according to the detected power supply voltage. Therefore, the first duty ratio becomes smaller than before the correction, and even when the power supply voltage rises above the third voltage, the rotation state of each set end of the motor can be kept as constant as possible.

In the motor control apparatus for an electric reel according to the eighth aspect, in the apparatus according to the seventh aspect, the motor control means compares the third voltage with the power supply voltage detected immediately after the power is turned on. In this case, it is possible to quickly recognize that another type of power supply is connected by comparison with the power supply voltage detected immediately after the power supply is turned on.

In the motor control apparatus for an electric reel according to the ninth aspect, in the apparatus according to the seventh aspect, the motor control means corrects the first duty ratio by multiplying the value obtained by dividing the third voltage by the detected power supply voltage by the first duty ratio. . In this case, the correction of the first duty ratio can be easily performed by a simple calculation.

The motor control apparatus for an electric reel according to the tenth aspect is the apparatus according to the seventh aspect, further comprising rotational speed detecting means for detecting a rotational speed of the spool, wherein the motor control means includes a motor drive means in a N-stage rotational state. In the first rotation state up to the first M (M: N / 2 or less integer) stage, the speed is controlled so that the speed detected by the rotational speed detecting means increases step by step for every M stage, followed by the N stage from the M + 1 stage. In the second rotation state, the torque is controlled so that the tension acting on the fishing line wound on the spool is increased step by step. In this case, in a step where the torque is relatively small, it is possible to prevent the motor from stopping regardless of the load fluctuation by controlling the speed constant so that the speed is not fluctuated by the load.

In the motor control apparatus for an electric reel according to the eleventh aspect, in the apparatus according to the seventh aspect, the first duty ratio according to the maximum step set by the rotation state operating means is 85% or less. In this case, since the 1st duty ratio is 85% or less also in the maximum stage, the trouble resulting from the temperature rise of a motor can be prevented beforehand.

The motor control apparatus for an electric reel according to the twelfth aspect is the apparatus according to the tenth aspect, wherein the rotational state operating means includes a lever member mounted to the reel unit so as to be swingable, and a swinging position for detecting the swinging position of the lever member. It has a position detecting means, and the motor control means divides the detection result of the oscillation position detecting means into N steps, and performs at least one of speed control and torque control. In this case, since the first duty ratio can be set by the swinging lever member, the step and the first duty ratio accompanying it can be set finely.

The motor control apparatus for an electric reel according to the thirteenth aspect is the device according to the seventh aspect, wherein the electric reel is disposed between the spool and the handle for rotating the spool, the clutch mechanism for connecting and blocking the spool and the handle, and the motor. And a clutch return mechanism for returning the clutch mechanism from the shutoff state to the connected state by reverse rotation of the motor, wherein the motor control means corrects the first duty ratio at the forward rotation of the motor, and at the second duty at the reverse rotation of the motor. The motor driving means is controlled by gradually increasing the duty ratio from the ratio to the third duty ratio which is greater than the second duty ratio and in which the clutch return mechanism is operable. In this case, since the clutch mechanism can be restored by using the reverse rotation of the motor, an actuator dedicated to clutch return is unnecessary. In addition, since the voltage can be increased by gradually increasing the second to third duty ratio at the time of motor reverse rotation, the shock torque at the start of reverse rotation becomes difficult to act on the component connected to the motor.

The motor control apparatus for an electric reel according to the fourteenth aspect of the invention is the apparatus according to the thirteenth aspect, wherein the motor control means sets the second and third duty ratios according to the power supply voltage when the detected power supply voltage exceeds the third voltage. Correct. In this case, even if the power supply voltage rises, the voltage rise which acts on the motor at the time of motor reverse rotation can be suppressed.

In the motor control apparatus for an electric reel according to the fifteenth aspect of the invention, in the invention described in the fourteenth aspect, the motor control means includes a second and third duty ratios multiplied by a value obtained by dividing the third voltage by the detected power supply voltage. The third duty ratio is corrected. In this case, the correction of the second and third duty ratios can be easily performed by a simple calculation.

It has a second oscillation shaft 217b which is molded and rotatably coupled to the inner circumferential portion of the potentiometer 104 in a rotatable manner. The first swing shaft 217a is made of metal, and the second swing shaft 217b is made of synthetic resin. A washer 226 is provided on the outer circumference of the first swing shaft 217a between the main body portion 216b of the operation portion 216 and the end portion of the storage portion 15c. The second swing shaft 217b is rotatably disposed on the inner circumferential side of the storage portion 15c, and a waterproof seal portion made of an elastic O-ring between the second swing shaft 217b and the storage portion 15c ( 224 is mounted.

Connected. 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 through the 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, the reel control unit 100 can detect the rocking angle of the adjustment lever 101 and detect the presence or absence of disconnection of the three lead wires 152a, 152b, and 152c by the output signal. . In other words, when the lead wires 152a and 152c are disconnected, the lever angle signal is 0 volts. Also, 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.

In addition, the reel control unit 100 has pulse width modulation for the buzzer 106 for various notifications, the depth display unit 98 for displaying depth information, the storage unit 107 for storing various data, and the motor 4. The motor drive circuit 108 for driving at a duty ratio (PWM) and the other input / output unit are connected. In the counter 5, as shown in FIG. 8, the 1st circuit board 150 and the 2nd circuit board 155 arrange | positioned at intervals below the 1st circuit board 150 are accommodated. . On the surface of the first circuit board 150, an electric component including a liquid crystal drive circuit for driving the liquid crystal display constituting the depth display portion 98 is mounted. An electronic component including a CPU constituting the reel control unit 100, an EEPROM constituting the storage unit 107, and the like are mounted on the rear surface. The second circuit board 155 is equipped with an electrical component including two FETs constituting the motor drive circuit 108, two hall elements constituting the buzzer 106, the spool sensor 102, and the like. The first circuit board 150 and the second circuit board 155 are electrically connected to each other by an interconnector 156 attached to the resin case and sandwiched between the two boards 150 and 155.

The depth display section 98 uses a segment type liquid crystal display including a seven-segment numerical display, and as shown in Fig. 13, the depth of the preparation, the position of the fish layer, the bottom position, and various modes ( Characters indicating a fish habitat stop mode, a display mode from the bottom, a line feed mode, a decoy mode, etc. are displayed. Among these, the attracted characters are turned on when the electric reel 1 and the sonar monitor 120 are connected by the power cord 130 and communicate with each other. Thereby, it can confirm at the moment that the sonar monitor 120 of the electric reel 1 became communicable. Further, a depth display portion 98a for displaying the depth of the preparation is provided in the center portion, and a set display portion 98b for displaying the set step ST, the fish habitat layer position, and the like, and a drop in power supply voltage are shown in the lower portion. The power supply figure 98c is provided.

The reel control unit 100 controls the motor 4 in 31 steps including, for example, turning off the motor 4 according to 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 steps, and it is judged which stage (ST) of 31 steps by the output. 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 correct | amended by the winding diameter for every step, the tension acting on the spool 3 becomes substantially constant, and it becomes difficult to produce a neck break etc. do. In the operation of the adjustment lever 101, the first duty ratio D1 does not exceed 85% even at the maximum stage. 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. Furthermore, 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 because the calculated depth and the set bottom position or the fish habitat layer position coincide, 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 count value for each predetermined pulse of the spool sensor 102 and a plurality of map data for converting the depth data LX of the gears of various fishing lines into pieces. 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, at the time of the clutch return operation by the reverse rotation of the motor 4, as shown in FIG. 21, the reel control unit 100 provides the duty ratio applied to the motor driving circuit 108 from the second duty ratio D2. It gradually raises to 3rd 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 first voltage V1 is preferably in the range of, for example, 2 volts to less than 6 volts. 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.

Protruding ends of the connecting shaft 93 are formed with chamfers 93a and 93b parallel to each other for rotatably mounting the first and second lever members 94 and 95.

The first lever member 94 is a member whose base end is rotatably mounted to the chamfer 93a on the side of the fixed frame 20 of the connecting shaft 93. 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 front 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 advancing and retracting member 96 is a plate member connected to the proximal end so that the second lever member 95 is rotatable and moves in a predetermined range. The advancing and retracting member 96 is divided by the oscillating tooth detent 82 and extends from the source of the first contact portion 96a and the first contact portion 96a to contact the lower surface of the oscillating tooth detent 82. The second contact portion 96b that is bent toward 91 is provided at its tip. The advance and retraction member 96 is capable of pressing the second contact portion 96b by the pressing member 91, and the first contact portion 96a presses the swinging tooth detent 82 and swings to the reverse rotation permission position. 11 can be moved between the release position (shown in FIG. 11) and the locking position (shown in FIG. 10) where the first contact portion 96a is separated from the swinging tooth detent 82 and cannot be pressed by the pressing member 91. Do. 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. As described above, the engaging member 61 is pivotally supported by the second protrusion 56b of the clutch cam 51, and engages with the ratchet teeth 62a of the ratchet wheel 62 at its distal end. 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 a level wind mechanism and a casting control mechanism are the same structures as a conventionally well-known electric reel, description is abbreviate | 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 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 off state is brought into place. 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.

When the clutch cam 51 rotates to the clutch off position, the retracting member 96 of the linkage 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 from (shown in FIG. 10) to a reverse rotation permission position (shown in FIG. 11). As a result, the motor 4 is in a state capable of reverse rotation. Moreover, when advancing member 96 advances to a release position, the 2nd contact part 96b is arrange | positioned in the position which the press 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 swinged to 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. The second contact portion 96b is pressed to retreat the retracting member 96 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. 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. 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. And the coil spring 54 is moved 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 the reverse rotation of this motor 4, the pressing member 91 attached to the mechanism mounting shaft 75 via the roller clutch 90 collides with the 2nd contact part 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. As a result, 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.

Further, 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. When the engagement member 61 is provided in this empty space, the expansion of the reel unit can be made smaller than in the configuration in which the engagement member is arranged behind or below the handle shaft as in the prior art.

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. Needless to say, 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 inner 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 only frictionally engages 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 attached to 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.

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 speed 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 received. 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 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 when the power supply voltage PV fluctuates, even when the duty ratio is controlled during forward rotation (wound winding), the rotational state of the spool 3 is less likely to fluctuate. 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 water 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 these judgment is complete | finished, it 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, it can be considered that the preparation is stopped in the fish breeding layer, and therefore, the flow advances to step S16 and sets the depth data LX to the fish breeding 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 indication, the portion 98a displays, for example, the letters Err5, Err6, and Err7 in correspondence with the disconnected lead wires 152a, 152b, and 152c. If other commands or input are made, the process shifts from step S12 to step S20 to perform 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 is kept 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, other key operations, for example, setting of the learning mode by operation of the memo button TB or menu button MB and the fast forward button HB for a predetermined time are performed. Determine whether or not.

When step ST of the adjustment lever 101 is not 0, it transfers from step S21 to step S27. In step S27, it is determined whether the depth data LX is 0 or less. In this embodiment, the adjustment lever 101 is operated in a state where the power distribution mode (the mode of automatically stopping the winding of the spool in the state where the gear is easily collected) is set in order to protect the fishing line. When the depth data LX is equal to or less than 0, 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 to move the adjustment lever 101 toward the step (ST = 0) which is the swing start position within two predetermined clicks (i.e., three or more different times) within a predetermined time (for example, three seconds). Direction rocking operation) is judged. By this special click operation, it is possible to drive in the direction of winding up the spool 3 in the power distribution mode and even when the depth data LX is 0 or less. 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 process proceeds to step S23 without any processing in order to prohibit the driving of the motor.

When the menu button MB is operated, the flow advances from step S23 to step S31, whereby the character or fish habitat layer position displayed on the water depth display section 98 blinks and is moved each time an operation is performed to select an 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. In this case, the subsequent depths are represented by the subsequent line lengths, with the depth data LX of the set position being zero.

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, and 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. If 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 1 to 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 5-30 stage.

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 for 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 flow advances 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 present 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 flow 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 flow advances to step S42.

When step ST is 5 to 30 steps | steps, it transfers to step S54 from step S42. 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 a winding diameter (for example, a spool trunk diameter) which is a reference to the step ST, and the duty ratio Dst is a value when the winding diameter becomes large. It gradually increases in proportion to the winding diameter. Thereby, the torque becomes large according to the winding diameter, and the tension of the fishing line which becomes large 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 which Hall element of the spool sensor 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, whenever the count value of the pulse output from the spool sensor 102 decreases, the data showing the relationship between the depth stored in the reel control unit 100 and the count value is read out based on the count value. The data LX is calculated. This depth data LX is displayed by the 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, processing of each operation mode is finished and the process 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 of the predetermined time or more as described above. 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, a duty ratio is gradually raised from 2nd duty ratio D2 to 3rd 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 the auto attracting mode is set, the attracting width which is the range for performing the attracting operation of the auto attracting mode and the pattern by the interval which turns on / off the motor 4 can be set.

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 displays information such as the position (FL), the seabed BL, and the like of the fish habitat layer position TL and the water depth data LX outputted from the other 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 the attraction operation from any position by the operation of the attraction 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 on / off attraction operation of the motor 4 in the range set by the attraction pattern set from the fish habitat layer position M. As shown in 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 the water depth data LX has reached the position LX = M-N * L which turns off the motor 4 by attracting operation. Herein, the variable L is a value that varies depending on the attraction pattern. When the gear reaches the attracting 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 process. In addition, in this embodiment, when auto attracting, the spool 3 is rotated in the file winding direction at the same interval and at the same stopping time depending on the number of attraction. However, the attraction pattern is not limited to this and may be an inequality interval or a variable stop time.

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. As a result, the fish is disposed at a position that is easy to catch when the 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 the timer T1, for example, when a common power source is used by a plurality of electric reels for boat fishing, it is possible to eliminate the voltage rise due to the instantaneous inrush voltage. If the timer T1 has not yet been set, the flow 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, damage to an electrical device will become less likely, for example, even if voltage rise continues. 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 or not 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 display on the depth display portion 98a of the depth display unit 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. When 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 second 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 and the routine returns to the main routine.

As described above, in this electric reel, the interlock mechanism 89 is pressed by the press 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. Since the pressurizing mechanism 88 is separated, the motor 4 and the interlocking mechanism 89 do not always need to 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 will not turn, and the manual return operation will be 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 comes into contact with the interlock mechanism 89, the pressing member 91 is not pressed, so that the file feeding mode can be smoothly performed.

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 start of 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, when the power supply voltage is detected and 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 smaller than before correction, and 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 comparing the detected power supply voltage with a predetermined voltage.

In addition, the motor 4 can be driven from the reference line length to the line winding side 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 is possible to rotate the spool 3 from the reference file length to the file winding side while preventing repair of the repair line due to an incorrect operation.

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, when the motor 4 is not rotating, judgment on the power supply voltage is always performed, thereby preventing damage to the device due to abnormality of the power supply voltage being used.

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 according to the stage. 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.

[Other Examples]

(a) In the above embodiment, the determination of the decrease in the power supply voltage is performed irrespective of the rotation of the motor, but may be performed when the motor is rotating or when the motor is not rotating.                     

(b) In the above embodiment, the abnormality notification to the rising side of the power supply voltage is performed by the character display of the depth display portion 98a. However, the method of the notification is not limited to the character display, and flashing or buzzer of the entire screen is turned on / off. It may be turned off. It is also possible to change the on / off time of the buzzer.

(c) In the above embodiment, the power supply voltage is detected to correct the duty ratio when the power is supplied. However, the power supply voltage may be detected after the power supply to correct the duty ratio.

(d) In the above embodiment, the motor 4 is disposed in the spool 3, but the present invention can also be applied to an electric reel in which the motor 4 is disposed in addition to the spool 3.

According to the present invention, since the abnormality of the power supply voltage is judged by the power supply voltage when the motor is not rotating, the rotation of the motor does not stop due to the power supply abnormality in use. In addition, since the judgment on the power supply voltage is always performed when the motor is not rotating, it is possible to prevent the device from being damaged due to abnormal supply voltage.
