Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric reel for smelt fishing in which a spool on which a fishing line is wound is rotationally driven by an electric motor.

In recent years, when ice fishing for smelt or boat fishing for smelt is performed on a frozen lake, fishing is carried out in a state where a short fishing rod is attached to a reel and placed on a table without always holding the fishing rod by hand. An electric reel for smelt fishing has been proposed. For example, Patent Literature 1 discloses an electric reel for smelt fishing in which an electric motor (hereinafter also referred to as a motor) is driven forward and reverse to automatically and continuously perform a lure operation. In such an electric reel for smelt fishing, the tackle is quickly dropped to a swimming layer (a layer where smelts and the like live, hereinafter referred to as a "shelf"), and when the tackle reaches a predetermined shelf, the motor is activated. It is possible to perform the above-described invitation operation by controlling the rotation.

JP 2019-030238

The electric fishing reel for smelt fishing described above can let out the fishing line by controlling the rotation of the motor when the tackle is released and when the smelt is lured on the shelf (jerking operation). When the fishing line is paid out by such a motor, if the reeling speed (reverse speed) of the spool is faster than the actual reeling speed of the fishing line, a backlash phenomenon occurs.

This backlash phenomenon is likely to occur when the weight is replaced with a lighter one during actual fishing. In other words, the angler needs to change the setting of the rotation speed of the motor when reeling out the fishing line to an appropriate value according to the weight of the weight. When changing to a weight, the spool rotates excessively and backlash is likely to occur. Also, when the jerking operation is performed on the shelf by controlling the motor, backlash is likely to occur unless it is controlled at an appropriate rotational speed. Furthermore, even if a motor rotation speed suitable for the weight of the weight is set, backlash may occur at the set speed due to the influence of water flow or the like.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an electric reel for smelt fishing that can be set to an optimum fishing line payout speed without knowing the weight of the weight. and

In order to achieve the above object, the electric reel for smelt fishing of the present invention comprises a reel body, a spool rotatably supported by the reel body and around which a fishing line is wound, and forward/reverse rotation of the spool. It has an electric motor for driving, and a control unit for controlling the driving of the electric motor. The control unit calculates the payout speed of the tackle equipped with a weight at the time of free fall, and adjusts the calculated payout speed to the calculated payout speed. Based on this, the optimum delivery speed is calculated and the electric motor is reversely driven.

According to the above configuration, the payout speed when the terminal tackle is free-falling does not cause backlash, so the payout speed is calculated. After that, when the tackle is reeled out by driving the electric motor in reverse rotation, the electric motor is controlled at an optimum speed based on the calculated reeling-out speed. There is no backlash even if the weight of the

In the above configuration, the optimum payout speed is determined based on the payout speed when the tackle is free-falling, and is the speed at which the tackle drops when the electric motor is reversely driven. For example, by controlling the reverse drive of the electric motor so that the payout speed is lower than the payout speed when the tackle is free-falling, it is possible to reliably prevent the occurrence of backlash. . In addition, the reverse driving of the electric motor at the optimum unwinding speed is performed, for example, by allowing the spool to fall freely in a freely rotatable state (clutch OFF), and after reaching a predetermined depth (shelf), turning the clutch ON. Alternatively, after the tackle is free-falling, the tackle is collected once, and the next tackle is charged by an electric motor.

According to the present invention, it is possible to obtain an electric reel for smelt fishing that can be set to an optimum fishing line payout speed without knowing the weight of the weight.

An embodiment of an electric reel for smelt fishing (hereinafter also simply referred to as a fishing reel) according to the present invention will be specifically described below with reference to the accompanying drawings.
In the electric reel for smelt fishing according to the present invention, a fishing rod can be directly attached to the reel body (having a rod attachment portion) as described later, and the output shaft of the electric motor is engaged with the spool so as to allow power transmission. (The transmission of power from the electric motor to the spool is connected and disconnected by releasably contacting the side surface of the spool with the output shaft of the electric motor perpendicular to the rotation axis of the spool, for example). , by controlling the voltage applied to the electric motor without shifting gears, the rotational speed, rotational direction and torque can be changed.

First, the overall construction of the fishing reel will be described with reference to FIGS. 1 to 3. FIG.
In the following description, the front-back direction and the left-right direction are the directions shown in FIG. 2, and the up-down direction is the direction shown in FIG.

A fishing reel 1 has a reel body 2. - 特許庁The reel body 2 has a housing 3 forming its outer shell. The housing 3 is made of a synthetic resin material such as ABS resin or polycarbonate.

The housing 3 is a box that is slightly curved and vertically long (long in the front-rear direction), and has a size that allows an angler to grasp it with his or her right or left hand. As shown in FIG. 3, the housing 3 is composed of a lower case 3A and a top cover 3B.

The top cover 3B is fixed to the lower case 3A by screwing or fitting, and defines a motor housing chamber for housing the electric motor 5 between the top cover 3B and the lower case 3A. Further, in the reel body 2, in this embodiment, the lower case 3A has an internal power source defining a storage section S that can detachably store, for example, a dry battery or a rechargeable battery 7 for supplying power to the electric motor 5. A housing 8 is provided.

Note that the reel body 2, or in this embodiment, the lower case 3A, has a housing portion S of the internal power supply housing 8 (in this embodiment, an opening of the lower case 3A for exposing the motor 5 and the like as a whole, including the housing portion S). ) to the outside is detachably attached.

Legs 12 are attached to the lower surface of the front side of the housing 3 so as to be spaced apart from each other in the lateral direction of the reel body 2 . The leg 12 is preferably made of, for example, a rubber-like elastic material that is softer than the housing 3, and is fixed to the bottom wall of the lower case 3A. The leg 12 functions as a grounding portion that comes into contact with the upper surface of a fishing platform that is set on, for example, a frozen lake surface when the reel body 2 is placed on the platform.

The leg 12 of the present embodiment includes projecting portions 13A that are fitted into the base end portions of the left and right sides and extend forward, and the distal ends of the projecting portions 13A are connected in the left-right direction and installed on the table. Auxiliary legs 13 are provided with connecting portions 13B. The auxiliary leg 13 can be slid in the front-rear direction with respect to the leg 12 so that the position of the connecting portion 13B can be adjusted.
By providing such auxiliary legs 13, the reel body 2 can be stably placed, and even if a large load is applied to the fishing line, for example, when many smelts are caught, the reel body can be stably mounted. 2 can be kept stable.

A support base 15 made of synthetic resin is fixed to the front end portion of the housing 3 by screwing or the like. A spool receiving portion 18 is provided.

The rod receiving portion 16 is positioned at the center of the front end of the housing 3 in the left-right direction. The rod receiving portion 16 has a support hole 16a that opens toward the front of the housing 3, and supports a fishing line guide 20 that guides the fishing line unwound from the spool. The fishing line guide 20 is held above the rod receiving portion 16 so as to be able to swing in the front-rear direction, and is normally biased and held in a state of being tilted forward as shown in FIG. Further, the spool receiving portion 18 of the support base 15 is arranged horizontally below the opening 3C of the top cover 3B.

As shown in FIG. 3, a pivot portion 21 is provided on the front bottom wall of the lower case 3A. A vertically extending spool shaft 23 a is supported by the shaft support portion 21 . The spool shaft 23a stands vertically from the bottom wall of the lower case 3A, penetrates the spool receiving portion 18, and protrudes upward.

A spool 23 made of synthetic resin or metal is rotatably supported above the spool shaft 23a. The spool 23 is positioned in the front part of the reel body 2 at the center in the left-right direction on the front side of the upper surface of the reel body 2 . Immediately behind the spool 23, a display unit (liquid crystal display device) 30 is provided on the upper surface of the housing 3 (on the top cover 3B) to display various information.

The spool 23 has a line winding body 23A on which the line is wound and a pair of flanges 23B and 23C, and rotates around a vertically disposed spool shaft 23a. The flanges 23B and 23C are disk-shaped and are coaxial with the line winding body 23A, and face each other vertically with the line winding body 23A interposed therebetween. In this case, the lower flange 23C is arranged on the upper surface of the spool receiving portion 18. As shown in FIG.

The spool shaft 23a coaxially penetrates the fishing line winding body 23A and protrudes above the upper flange 23B. A cap nut 25 is screwed onto the upper end of the spool shaft 23a. The cap nut 25 sandwiches the spool 23 between itself and the spool receiving portion 18 , whereby the spool 23 is rotatably supported on the front portion of the reel body 2 . The spool 23 is positioned inside the opening 3C of the top cover 3B.

As shown in FIG. 3, a fishing rod 80 is fitted into the support hole 16a of the rod receiving portion 16. As shown in FIG. The fishing rod 80 may have a short length of, for example, about 15 cm, and horizontally protrudes forward from the front end of the reel body 2 .

A plurality of fishing line guides (not shown) are attached to the outer peripheral surface of the fishing rod 80 . These fishing line guides are arranged in a line with intervals in the longitudinal direction of the fishing rod 80 . A fishing line (not shown) drawn out from the spool 23 is led from the fishing line guide 20 of the reel body 2 to the tip of the fishing rod 80 via the fishing line guide of the fishing rod 80, and then spreads from the tip of the fishing rod 80 to the surface of the lake, for example. It is guided into the water through a hole.

The electric motor 5 in the motor housing chamber formed between the top cover 3B and the lower case 3A can rotate forward and backward by electrical control. ) and a metal output shaft 5A projecting from the front end of the motor housing. The electric motor 5 is installed behind the spool 23 in a horizontal orientation with the output shaft 5</b>A along the longitudinal direction of the housing 3 .

The output shaft 5A of the motor 5 is positioned immediately behind the spool shaft 23a and maintains a positional relationship such that it is perpendicular to the spool shaft 23a. A front end portion of the output shaft 5A is positioned below a flange 23C on the lower side of the spool 23. As shown in FIG.

A cylindrical torque transmission member 5B is attached to the outer circumference of the output shaft 5A. The torque transmission member 5B is made of, for example, a synthetic resin material softer than the spool 23 or a rubber-like elastic body. In the state shown in FIG. 3, the outer peripheral surface of the torque transmission member 5B is in contact with the lower surface of the lower flange 23C of the spool 23. As shown in FIG.

The motor housing of the electric motor 5 (therefore, the electric motor 5) has a first horizontal position shown in FIG. position indicated by a dotted line).

In the first position, as shown in FIG. 3, the output shaft 5A of the electric motor 5 extends horizontally along the front-rear direction of the housing 3, and the outer peripheral surface of the torque transmission member 5B is located below the spool 23. It abuts on the lower surface of the flange 23C. By this contact, frictional resistance is applied to the contact portion between the flange 23C and the torque transmission member 5B, and the output shaft 5A of the electric motor 5 and the spool 23 are mechanically connected (clutch ON). ).

As a result, free rotation of the spool 23 is prevented by frictional resistance. When the electric motor 5 is further rotated forward and reverse in this state, the torque of the output shaft 5A is transmitted to the spool 23 via the torque transmission member 5B, and the spool 23 rotates in the direction to wind up the fishing line or in the direction to let out the fishing line. . That is, in this configuration, the output shaft 5A of the electric motor 5 is engaged with the spool 23 so as to transmit power, and the spool 23 is rotated in the forward and reverse directions by driving the electric motor 5 forward and backward. The fishing line is wound on the spool 23, or the fishing line is paid out from the spool 23.

On the other hand, at the second position, the electric motor 5 is tilted, the output shaft 5A is lowered forward, and the outer peripheral surface of the torque transmission member 5B is separated from the lower surface of the flange 23C on the lower side of the spool 23. As a result, the mechanical connection between the output shaft 5A of the electric motor 5 and the spool 23 is released (clutch OFF), and no frictional resistance is applied between the torque transmission member 5B and the spool 23. Therefore, the spool 23 is in a free state in which it is allowed to rotate freely in the direction of reeling in the fishing line and in the direction of reeling out the line.

The electric motor 5 is always elastically biased toward the first position via a tension coil spring (not shown). Therefore, as long as the motor 5 is in the first position, the outer peripheral surface of the torque transmission member 5B is elastically pressed against the lower surface of the lower flange 23C of the spool 23. As shown in FIG.

Further, switching between the first position and the second position of the electric motor 5 (motor housing) is performed by an operation body 28 provided protruding from the top cover 3B. The operation body 28 is supported so as to be able to swing in the lateral direction with respect to the reel body 2. The position (left side) shown in FIGS. 1 and 2 is the clutch ON position, and the opposite position (right side) is the clutch OFF position. It's becoming The lower end of the operating body 28 is directly or indirectly engaged with the torque transmission member 5B, and by moving the operating body from the clutch ON position to the clutch OFF position, the torque transmission member 5B and the electric motor 5 are driven together. is pushed downward (to the second position). As a result, the mechanical connection between the output shaft 5A of the electric motor 5 and the spool 23 is released. Further, when the operating body 28 is moved from the clutch OFF position to the clutch ON position, the electric motor 5 is returned to the first position by the urging force of the tension coil spring described above.

As described above, the operating body 28 switches between a state in which the output shaft 5A of the electric motor 5 and the spool 23 are mechanically connected (clutch ON) and a state in which the connection is released (clutch OFF). It is configured. That is, the operating body 28 functions as a clutch mechanism for switching between a power transmission state in which the power of the electric motor 5 can be transmitted to the spool 23 and a power cutoff state in which the power transmission from the electric motor 5 to the spool 23 is cut off. fulfill a function.
In addition to the operation of the operating body 28 described above, the clutch mechanism can be changed from the clutch OFF state to the clutch ON state when the fishing line has reached a predetermined amount (the tackle has reached a set depth) in the clutch OFF state. configured to automatically return to For example, it is possible to provide a drive member such as a solenoid and drive the drive member to automatically return the operating body 28 to the clutch ON position when the fishing line is drawn out by a predetermined amount.

The reel body 2 has an operation button (operation switch) for turning ON/OFF the electric motor 5, driving the electric motor 5 (normal rotation, reverse rotation, jogging, and stopping of the spool 23), setting various modes, and the like. Multiple are provided. For example, in this embodiment, an ON/OFF button 31 and a setting button 32 for selecting and storing various modes are arranged side by side on the lower side of the display section 30. A motor drive button 33 is arranged in the . In this case, the motor drive button 33 is configured so that the same motor drive operation can be performed whether the reel body is gripped with the right hand or the reel body with the left hand. By operating these operation buttons 31 to 33 (instantaneous pressing operation, long pressing operation, simultaneous operation, etc.), the driving of the fishing reel is controlled.
The arrangement position, the number of arrangement, the operation mode, etc. of the operation buttons for driving the fishing reel are not limited to the configuration shown in the drawings, and various modifications are possible. be.

FIG. 4 is a block diagram showing a schematic configuration of the control system of the electric reel for smelt fishing.
As shown in the figure, a control unit 40 for controlling the operation of the fishing reel includes a spool rotation detection unit 41, a clutch mechanism 42, a motor drive circuit 43, a fishing line guide detection sensor 45, a display unit 30, and an operation control unit 40 via a bus line 50. Information is transmitted/received to/from components such as the buttons 31 to 33 and the alarm unit 46 .

The control unit 40 executes various control operations such as display control of the display unit 30 and drive control of the electric motor 5 according to the ROM storing various operation programs and control tables for controlling the fishing reel and the operation program. It is configured as a microcomputer including a CPU, a RAM that functions as a temporary storage unit when executing an operation program, a timer that measures a predetermined time, and the like.

The spool rotation detection unit 41 has a function of detecting the amount of fishing line that is drawn out from the spool, and can be composed of, for example, a sensor (such as a Hall element) that detects changes in the magnetic field of a magnet installed on the spool. be. The spool rotation detection unit 41 detects the number of rotations of the spool (the amount of fishing line paid out), the direction of rotation, and the length of the drawn line, and detects the water depth position of the tackle 82 attached to the fishing line 81 (see FIG. 5) drawn out from the spool. It has a function to measure.

As described above, the clutch mechanism 42 automatically turns on the clutch when the spool rotation detector 41 detects that the fishing line has been reeled out by a predetermined amount while the fishing line is being reeled out in the clutch-off state. It has a function to restore.

The motor drive circuit 43 is configured by, for example, a PWM drive circuit that PWM-drives the electric motor 5 . The PWM drive circuit has a function of adjusting the rotational speed of the electric motor 5 by changing the PWM duty ratio. As will be described later, the electric motor 5 of the present invention is driven and controlled by a control program so as to slowly drop the tackle from a predetermined position in front of the shelf when the fishing line is reeled out. Further, if necessary, it is driven and controlled to execute a jerking mode in which the tackle is moved up and down continuously or intermittently within the shelf.

The fishing line guide sensor 45 has a function of stopping the winding drive of the electric motor 5 when detecting that the fishing line guide 20 has fallen backward against the urging force continuously for a certain period of time during winding of the fishing line. have As a result, troubles such as the tackle winding around the spool can be avoided.

The display unit 30 displays, for example, the type of mode that can be set by the fisherman, the actually set mode, the amount of fishing line paid out (measured water depth), speed, time, and the like. In addition, various alarm sounds are emitted from the alarm sound unit 46, for example, an operation sound that notifies each time an operation button is pressed, and that a predetermined water depth (designated shelf, predetermined position in front of the designated shelf, etc.) has been reached. An alarm sound or the like for notifying the

The control unit 40 may be configured to acquire information from the external device 48 and control various operations. For example, shelf height information may be acquired from a water depth measuring device, a fish finder, or the like that is wired or wirelessly connected to the fishing reel, and the electric motor 5 may be driven and controlled based on the acquired shelf information.

Next, the control operation when smelt is caught using the fishing reel 1 configured as described above, in particular, the control operation of inserting a tackle and feeding the tackle into the indicator shelf will be described with reference to FIGS. 5 to 7. FIG. do.

Smelt has the property of migrating in groups within a given shelf. Normally, when throwing in a tackle toward a shelf, the clutch is turned off to allow the tackle to fall freely, and when the tackle reaches the shelf, the clutch is turned on. In this case, the tackle may be set by free fall by releasing the clutch, or by rotating the spool in the fishing line payout direction at an arbitrary speed (reverse drive of the electric motor).

A first control mode example will be described below with reference to FIGS. 5 and 6. FIG.
As an example, it is assumed that the shelf D where smelt are clustered is at a depth H of 10 m from the water surface P (see FIG. 5). In this case, a tackle 82 is fastened to the tip of a fishing line 81 falling from the tip of a fishing rod 80 attached to the fishing reel 1, and a weight 83 is attached to the tip.

As shown in the flow chart of FIG. 6, shelf setting (designated shelf: 10 m) is first performed (step S1). This shelf information is set by information from an external device 48 such as a fish finder, instruction shelf information from a boatman in the case of a dome boat, or the experience of an angler. Press any one to enter. Alternatively, it may be configured to be automatically set in conjunction with the external device 48 .

Next, when it is detected that the clutch is turned off, the tackle (fishing line) is free-falling and let out at a predetermined let-out speed (step S2; Yes). Then, during the reeling-out of the tackle, the reeling-out speed of the tackle and the optimal reeling-out speed are calculated (step S3).

Regarding the method of processing in step S3, for example, while measuring the water depth (spool rotation speed x spool diameter x 3.14), water depth information for a certain depth (distance) is detected, and the water depth is reached. The timer of the control unit measures the time taken, and from the water depth information and the time information, it is possible to calculate the delivery speed of the tackle during free fall. Further, the optimum delivery speed is determined based on the calculated delivery speed during free fall, and is determined within a range in which backlash does not occur when the electric motor is reversely driven.

This optimum payout speed can be determined based on a pre-stored control table. Alternatively, if the reeling speed is set to be less than or equal to that calculated at the time of free fall, the spool will not over-rotate and the occurrence of backlash can be reliably prevented. The optimum delivery speed may be a constant value, or may be variable within a range in which backlash does not occur when the jerking mode or the like is performed.

Then, when the control unit detects that the tackle has reached the set rack, it turns on the clutch (step S4; Yes). The tackle is stopped (temporarily stopped) by turning on the clutch (step S5). It should be noted that although it has been described that the "device" has reached the set shelf, the device may reach the shelf when the "weight" attached to the device reaches the shelf.

Subsequently, various invitation modes are performed within the shelf (step S6). In this invitation mode, the electric motor repeats forward rotation and reverse rotation continuously or intermittently. controlled (step S6).

This lure mode is repeated until the electric motor is driven forward and the tackle is recovered (step S7; No, step S6). Also, if the tackle recovery operation has been performed (step S7; Yes), the process returns to step S2 described above.

After returning to step S2, the above-described steps S3 to S6 are repeated again. That is, even if the angler recovers the tackle and changes the weight, each time the tackle free-falls, the processing for calculating the reeling-out speed and the optimum reeling-out speed of the tackle is executed, and the electric motor is reversely driven. Since it is controlled, the angler can prevent the occurrence of backlash in the same state without having to perform a separate operation to change the falling speed. In addition, it is possible to prevent the occurrence of backlash due to a setting error (such as when the weight is changed but not set to match the weight of the weight).

In the above-described process, when the tackle is dropped by the reverse driving of the electric motor in the second and subsequent tackle insertions (step S7; Yes, step S2; No), control is performed so as to achieve the calculated optimum payout speed. (Step S8), no backlash occurs. After the terminal tackle reaches the shelf, various lure modes are performed at the optimum delivery speed (or a speed lower than that) in step S6 (step S9; Yes, step S6).

After setting the shelf (step S1), the tackle may be paid out by suddenly turning the clutch ON and driving the electric reel in the reverse direction. In such an operation, the reverse drive speed may be controlled to be slow until the free fall delivery speed is calculated. Alternatively, a manual or the like may clearly indicate that the first tackle drop should be performed with the clutch OFF.

As described above, the feeding speed of the terminal tackle is calculated during free fall, and the subsequent reverse driving of the electric motor is automatically controlled to the optimum feeding speed, so that backlash can be prevented. In addition, since the free fall speed of the entire fishing line (device) including the bait, hook, and weight is calculated, even if there are various changes in the situation, such as changing the weight or water flow, the optimum speed that does not cause backlash is always maintained. It is possible to pay out the gimmick in a good state.

By the way, the smelt is a migratory fish, and if the device is dropped and dropped onto the shelf at the same speed, the smelts in the shelf may perceive an abnormality and escape. In such a case, the tackle should be dropped toward the shelf in a short period of time, and the speed of reeling out the fishing line should be lowered from a predetermined position in front of the shelf so that the smelt swarming on the shelf will not run away when they sense an abnormality. It is preferable to control the reverse drive of the electric motor 5 immediately.
A second control mode example will be described below with reference to FIGS. 5 and 7. FIG.

As an example, it is assumed that the shelf D where smelt are clustered is at a depth H of 10 m from the water surface P (see FIG. 5). In this case, a tackle 82 is fastened to the tip of a fishing line 81 falling from the tip of a fishing rod 80 attached to the fishing reel 1, and a weight 83 is attached to the tip. Here, from a predetermined position D1 in front of the shelf D, the reverse driving of the electric motor is controlled at low speed.
Although the distance H1 from the shelf D to the predetermined position D1 is arbitrary, the distance is set to such a degree that the tackle falling to the predetermined position D1 cannot be detected by smelt.
As a result of specific verification, the range of 50 cm to 100 cm is preferable (50 cm in the following description), but this distance H1 is set freely by the user according to the conditions of the fishing spot. Also good. Alternatively, if the user does not set it, it can be set in advance within the range of 50 cm to 100 cm.

As shown in the flowchart of FIG. 7, first, shelf setting (designated shelf: 10 m) is performed (step S11). This shelf information is set by information from an external device 48 such as a fish finder, instruction shelf information from a boatman in the case of a dome boat, or the experience of an angler. Press any one to enter. Alternatively, it may be configured to be automatically set in conjunction with the external device 48 .

Next, when it is detected that the clutch is turned off, the tackle (fishing line) is free-falling and let out at a predetermined payout speed (step S12; Yes). Similar to step S3 of 1, the tackle pay-out speed calculation and optimum pay-out speed calculation processing are performed (step S13). Then, the control unit detects that the tackle reaches a predetermined position (here, 9m50cm) in front of the set shelf, and turns on the clutch when the tackle reaches that position (Step S14; Yes, step S15). When the clutch is turned on, the tackle stops (temporarily stops), so the smelt swarming on the shelf do not sense the falling tackle and do not run away.

Next, the electric motor is reversely driven at a low speed to drop the tackle into the shelf (step S16). The drop from the predetermined position in front of this shelf should be less than the optimum delivery speed (lower than the free-fall delivery speed) calculated in step S13, and is set to a speed that does not surprise the smelt. I wish I had. Specifically, by setting it to be slower than the delivery speed (falling speed) of the device that free-falls with a 10-g weight fastened, it becomes difficult for the smelt to escape. In step S15 described above, instead of temporarily stopping the tackle, the electric motor may be reversely driven at a low speed at the same time as the clutch is turned on to gradually drop the tackle.

As described above, when the tackle reaches the rack by low-speed driving of the electric motor (step S16, step S17; Yes), the luring mode (jerking operation) is performed thereafter (step S18). As for this invitation mode, as in step S6 in the flowchart of FIG. speed below that).

This lure mode is repeated until the electric motor is driven forward and the tackle is recovered (step S19; No, step S18). Also, if the tackle recovery operation has been performed (step S19; Yes), the process returns to step S12 described above.

After returning to step S12, the above-described steps S13 to S17 are repeated again. In other words, each time the tackle is free-falling, the reeling-out speed of the tackle and the optimum reeling-out speed are calculated to control the reverse drive of the electric motor. It is possible to prevent the occurrence of backlash in the state as it is without performing any maintenance. In addition, it is possible to prevent the occurrence of backlash due to a setting error (such as when the weight is changed but not set to match the weight of the weight).

Further, in the above-described process, when the tackle is dropped by the reverse drive of the electric motor in the second and subsequent tackle insertion, the calculated optimum payout speed is obtained as in steps S8 and S9 of the flow chart of FIG. (Steps S20 and S21), so backlash does not occur.

According to the configuration of the present embodiment described above, even if the angler does not set the reverse driving speed of the electric motor according to the weight of the weight, it is possible to let out the tackle without causing backlash. Become. In particular, when the angler changes the weight, he/she does not have to grasp the weight of the weight, and the reverse driving speed is automatically controlled to the optimum, so problems such as setting errors and forgetting to set occur. There is no In addition, even if the falling state of the terminal tackle changes due to the influence of water currents, etc., the falling speed is changed to the optimum, so that it is not affected by the environment or the like.

The calculation processing in steps S3 and S13 in the flowcharts of FIGS. 6 and 7 is an example. As for the method of calculating the free fall of the tackle, if the speed when it is falling can be detected, the calculation method can be appropriately modified. For example, if the fishing line is marked at regular intervals and a sensor for detecting the passage of the marking is provided on the reel body, the free fall speed and the falling speed during the reverse rotation of the motor can be detected. be. As for the calculation method of the optimum delivery speed, an appropriate value may be determined for each weight of the weight, and the weight information of the weight in use may be used for automatic setting. In this case, even if the weight of the weight is unknown, for example, it is possible to store the time when the device equipped with the weight whose weight information is specified free-falls and reaches a predetermined water depth. It is also possible to identify the weight of the unknown weight by comparing the time when the device equipped with the weight of unknown weight free-falls and reaches the predetermined water depth with the stored time. It is possible.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention.
The fishing reel of the present invention only needs to have the function of controlling the feeding of the tackle to the rack as described above. Various functions such as a shipboard stop function and a backlash prevention function may be provided separately. Further, the shape and size of the reel body 2, the display mode of the display section, the arrangement of the operation buttons, the operation method, etc. are not limited, and various modifications are possible.
