Description

  The present invention relates to a casting support apparatus that supports determination of an appropriate release timing in casting.

  Casting is performed to throw the device attached to the tip of the fishing rod to a remote landing point. When casting using a bait casting reel, hold the spool with your thumb at the start of casting to regulate the rotation of the spool, and perform a release operation to release the thumb from the spool at a predetermined timing after the start of casting. To allow the spool to rotate freely. A similar release operation is required when using a spinning reel.

  In casting, the landing point of the device varies according to the speed and moving direction of the device at the time when the release operation is performed. Therefore, in order to land the device at a desired landing point, it is necessary to perform a release operation at an appropriate timing after the start of casting. If the release timing for performing the release operation is too early or too late, the device will fly in a direction significantly deviating from the target according to the swing trajectory. For example, if the release timing is too early in overhead casting, the device will fly in a direction close to the top. As a result, the device lands before the target landing point. On the other hand, if the release timing is too late in overhead casting, the device will land before the target immediately after the release.

  Thus, in order to perform casting properly, a certain skill is required of the angler. Therefore, an apparatus that supports an angler who is not skilled in casting has been proposed. For example, Japanese Patent Application Laid-Open No. 2009-159847 discloses a device that prevents backlash during casting by automatically braking a spool of a bait casting reel during casting. Japanese Patent Application Laid-Open Nos. 2001-095443 and 2004-208630 disclose devices that automatically apply a braking force to a spool during casting.

  Japanese Patent Application Laid-Open No. 2014-082938 discloses that when the device is determined to be in the landing state, the angler can easily recognize the landing of the device by notifying that the device is in the landing state. An apparatus is disclosed.

  As described above, in casting, it is necessary to perform a release operation at an appropriate release timing. This determination of an appropriate release timing requires a particular skill in casting. However, conventional apparatuses for supporting casting are limited to those that automatically brake the spool and notify the timing of landing. To date, no device is known to assist in determining the appropriate release timing.

  One of the objects of the present invention is to provide a casting support apparatus that supports determination of an appropriate release timing in casting. Other objects of the present invention will become apparent by referring to the entire specification.

  A casting support apparatus according to an embodiment of the present invention includes a notification unit that performs notification, and a timing determination unit that determines that a release timing for releasing the device has arrived based on a moving direction of the fishing device to be cast. And a notification control unit that causes the notification unit to notify when it is determined by the timing determination unit that the release timing has arrived.

  According to this embodiment, when the angler casts a device by casting, the release timing is determined based on the moving direction of the device. Then, the notification unit notifies the determined release timing. Therefore, the angler can grasp an appropriate release timing by the notification from the notification unit. The angler can easily land the device at a desired landing point by performing the release operation at the notified release timing.

  In one embodiment of the present invention, the timing determination unit is configured to obtain the moving direction of the device based on a sensor signal representing a physical quantity detected by a sensor unit including at least one sensor. The sensor unit includes, for example, at least one sensor provided for the device. At least one sensor provided for this device is, for example, a motion sensor. This motion sensor can output a sensor signal representing at least one of the device speed, acceleration, angular velocity, angular acceleration, and posture angle.

  In an embodiment of the present invention, the sensor unit may include a tension sensor that detects a tension acting on a fishing line to which a device is attached. In this case, the timing determination unit is configured to detect the moving direction of the device based on a tension signal representing a tension acting on the fishing line from the tension sensor. In addition to the tension signal detected by the tension sensor, the timing determination unit, if necessary, the length of the fishing rod in the axial direction, the length of the fishing line from the tip of the fishing rod to the device (trimming length), The moving direction of the device can be detected based on the mass of the device and fishing rod characteristic information indicating the characteristics of the fishing rod. The fishing rod characteristic information includes at least one of the length of the fishing rod (the rod length), the mass matrix M (x), the stiffness matrix K (x), and the damping matrix C (x).

  In one embodiment of the present invention, the timing determination unit is configured to determine that the release timing has arrived when it is determined that an angle of the device moving direction with respect to a vertical direction has reached a predetermined angle. This predetermined angle is set to 45 degrees, for example. This predetermined angle can be appropriately set according to the angle of the angler's swing or release action.

  In one embodiment of the present invention, the timing determination unit determines that an angle of the moving direction of the device with respect to a vertical direction is within a predetermined angle, and detects that the device speed has a maximum value. In the case, it is configured to determine that the release timing has arrived. Generally, the faster the mechanism moves at the time of release, the farther the mechanism can be skipped. In the above embodiment, it is possible to notify the angler at the maximum value of the moving speed of the device by determining that the release timing has arrived when it is detected that the device speed has shown the maximum value. it can. Thereby, the angler can fly the device far by releasing the device at the notification timing of the notification unit.

  In one embodiment of the present invention, the timing determination unit is configured to determine that the release timing has arrived when it is determined that the moving direction of the device is within a predetermined angle with respect to the target direction. According to these embodiments, the release timing is determined based not only on the angle of the mechanism moving direction with respect to the vertical direction but also on the angle formed with respect to the target direction. Therefore, even when performing so-called side hand casting in which the fishing rod is swung in a trajectory inclined with respect to the vertical plane, an appropriate release timing for throwing the device in the target direction can be notified to the angler.

  In one embodiment of the present invention, the notification unit is configured to notify the angler of the release timing by at least one of sound, light, and vibration.

  A casting support apparatus according to an embodiment of the present invention includes a timing determination unit that determines that a release timing for releasing a device has arrived based on a moving direction of the fishing device to be cast, and the fishing reel. A reel control unit for controlling. The fishing reel includes a handle, a spool around which a fishing line is wound, a clutch capable of switching between an on state in which rotation is transmitted between the handle and the spool and an off state in which transmission of the rotation is blocked. Mechanism. The reel control unit is configured to switch the clutch mechanism to an off state when the timing determining unit determines that the release timing has arrived.

  According to the embodiment, when the angler casts a device, the release timing is determined based on the moving direction of the device. Then, the clutch mechanism is switched to the off state at the determined release timing. Therefore, casting can be performed without manually switching the clutch mechanism to the off state.

  According to the embodiment of the present invention, it is possible to provide a casting support apparatus that supports determination of an appropriate release timing.

  Hereinafter, various embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings, common components are denoted by common reference numerals. It should also be noted that the drawings are not necessarily drawn to scale for convenience of explanation.

  With reference mainly to FIG. 1 thru | or FIG. 3, the casting assistance apparatus which concerns on one Embodiment of this invention is demonstrated. FIG. 1 is a side view of a fishing rod 1 provided with a casting support apparatus 50 according to an embodiment of the present invention, FIG. 2 is a block diagram illustrating functions of the casting support apparatus 50, and FIG. It is a block diagram explaining the function of the control part 51 of the said casting assistance apparatus 50. FIG. In the illustrated embodiment, a reel R is attached to the fishing rod 1, and a casting support device 50 is provided on the reel R. That is, the casting support device 50 is provided on the fishing rod 1 via the reel R.

  The fishing rod 1 is composed of a single rod or a plurality of rods. Each of the rods constituting the fishing rod 1 can be formed using a prepreg sheet in which a carbon fiber is impregnated with a synthetic resin. Each of the housings may be formed to have a tapered shape that tapers in the tip direction.

  A plurality of fishing line guides 10 for guiding the fishing line L fed from the reel R to the tip of the fishing rod 1 are provided on the outer peripheral surface of the fishing rod 1.

  The fishing reel R is mounted on a reel sheet that is externally mounted on the rod body of the fishing rod 1. In the present invention, for example, various fishing reels such as a spinning reel, a double bearing reel, and a single bearing reel can be used as the fishing reel R.

  A device 20 is attached to the tip of the fishing line L extending from the tip. The device 20 is, for example, various articles used as lures, weights, baskets, and other fishing devices. The device 20 is thrown by casting.

  In one embodiment of the present invention, a motion sensor 31 is attached to the device 20 to detect at least one of acceleration, angular velocity, posture angle, and angular acceleration of the device 20. The motion sensor 31 can be attached to any place of the device 20. The motion sensor 31 is, for example, one of a triaxial angular velocity sensor, a triaxial acceleration sensor, and a geomagnetic sensor, or a combination thereof. The motion sensor 31 can detect, for example, the triaxial angular velocity of the device 20, the triaxial translational acceleration, the inclination with respect to the direction of gravity (vertical direction), and the direction. As the motion sensor 31, various commercially available motion sensors can be used.

  The reel R includes a handle and a spool around which a fishing line is wound, similarly to a known general fishing reel. When the angler rotates the handle, the rotation of the handle is transmitted to the rotating body for winding the fishing line L. As the rotating body rotates, the fishing line L is wound around the spool. When the reel R is a bait casting reel, the rotating body that rotates according to the rotation of the handle is a spool. When the reel R is a spinning reel, the rotating body that rotates according to the rotation of the handle is a rotor.

  The reel R is between a rotating body (a spool in the case of a bait casting reel and a rotor in the case of a spinning reel) that rotates according to the rotation of the handle to wind up the fishing line. A clutch mechanism 42 for turning on / off rotation transmission is provided. That is, the clutch mechanism 42 is configured to be able to switch between an on state in which rotation is transmitted between the handle and the rotating body and an off state in which transmission of this rotation is blocked. The clutch mechanism 42 is provided with a clutch drive mechanism 42a that switches between an ON state and an OFF state of the clutch mechanism 42 using a mechanical output from the prime mover. The clutch drive mechanism 42a is configured to switch the clutch mechanism 42 between an ON state and an OFF state by using various motors such as a servo motor or various actuators such as a solenoid actuator. A mechanism for switching the clutch mechanism using the mechanical output of such a motor or actuator is known. For example, Japanese Patent Laid-Open No. 6-335341 discloses a device that switches a clutch mechanism by using a motor for driving a spool (corresponding to the drive motor 8 in the illustrated embodiment).

  In one embodiment of the present invention, a motion sensor 32 is attached to the reel R. The motion sensor 32 is configured to detect at least one of the acceleration, angular velocity, posture angle, and angular acceleration of the reel R. In one embodiment, the motion sensor 32 is one or a combination of a three-axis angular velocity sensor, a three-axis acceleration sensor, and a geomagnetic sensor. The motion sensor 32 can detect, for example, the triaxial angular velocity of the reel R, the triaxial translational acceleration, the inclination with respect to the gravity direction (vertical direction), and the direction. As the motion sensor 32, various commercially available motion sensors can be used. The reel R is fixed to the fishing rod 1 at the time of casting. Further, the position where the reel R of the fishing rod 1 is attached or the base side thereof is hardly elastically deformed even during casting. Therefore, from the detection value of the motion sensor 32, the movement (angular velocity, translational acceleration, etc.) of the portion of the fishing rod 1 that is not elastically deformed (the portion on the base side of the fishing rod 1 including the reel attachment position where the reel R is attached) can be obtained. it can.

  In place of the motion sensor 32 or in addition to the motion sensor 32, another motion sensor is provided on a portion of the fishing rod 1 that is not elastically deformed (for example, a portion near the attachment position of the reel R of the fishing rod 1 or a portion on the base side thereof). It may be provided. The motion sensor provided in the fishing rod 1 is configured in the same manner as the motion sensor 32. For example, the three-axis angular velocity in the vicinity of the mounting position of the reel R of the fishing rod 1 or the base side portion thereof, the three-axis translational acceleration, The inclination and direction with respect to the direction of gravity (vertical direction) can be detected.

  In one embodiment of the present invention, the reel R is provided with a tension sensor 33 that detects the tension acting on the fishing line L. A mechanism for detecting the tension acting on the fishing line L is known. As the tension sensor 33, various known tension detection mechanisms can be used. Conventional mechanisms for detecting the tension acting on the fishing line L are described in, for example, Japanese Patent Laid-Open Nos. 8-103195 and 11-4030, and the mechanisms described in these publications are disclosed in the present disclosure. Can be used as the tension sensor 33 in FIG.

  The casting support apparatus 50 according to the embodiment of the present invention calculates the moving direction of the device 20 based on the detection signals from the above-described or other various sensors, and the device 20 based on the moving direction of the device 20. Is configured to determine that the release timing for releasing the has arrived. Moreover, the casting assistance apparatus 50 which concerns on one Embodiment of this invention is comprised so that an angler may be notified that the release timing has come. As shown in FIG. 2, the casting support apparatus 50 includes a control unit 51 that performs various processes such as determination that the release timing has arrived, a notification unit 56 that performs notification, and an operation button 57. As will be described later, the notification unit 56 is configured to emit at least one of sound, light, and vibration when it is determined that the release timing has arrived. The notification unit 56 is, for example, various buzzers that emit sound. The angler can know that the release timing has arrived by sensing at least one of the sound, light, and vibration generated by the notification unit 56. The operation button 57 is configured to output an operation signal in accordance with an angler's operation. Details of the operation button 57 will be described later.

  The control unit 51 includes a CPU 52 that performs various calculations, a ROM 53 that stores various programs and setting information, and a RAM 54 that temporarily stores various data. As shown in the figure, the operating elements of the controller 51 are electrically connected to each other via an I / O port 55 so that signals can be transmitted and received. The control unit 51 executes a predetermined program stored in the ROM 53 by the function of the CPU 52, and sends a control signal generated in accordance with the program to each operating element (notification unit 56, etc.) via the I / O port 55. Each actuating element is controlled by supplying.

  The motion sensors 31 and 32 and the tension sensor 33 described above are also connected to the I / O port 55. The motion sensor 31 detects at least one of the acceleration, the angular velocity, the posture angle, and the angular acceleration of the device 20, and detects at least one of the detected acceleration, angular velocity, posture angle, and angular acceleration of the device 20. A signal is transmitted to the control unit 51. The motion sensor 32 detects at least one of the acceleration, angular velocity, posture angle, and angular acceleration of the reel R, and detects at least one of the detected acceleration, angular velocity, posture angle, and angular acceleration of the reel R. A signal is transmitted to the control unit 51. The tension sensor 33 detects the tension of the fishing line L and transmits a detection signal indicating the detected tension to the control unit 51. Since the motion sensor 31 is provided remotely from the reel R (in the device 20 described above), the detection signal of the motion sensor 31 may be wirelessly transmitted to the casting support device 50. In this case, the motion sensor 31 is connected to the I / O port 55 via a wireless communication interface (not shown).

  Next, functions of the casting support apparatus 50 will be described. The casting support apparatus 50 according to an embodiment of the present invention executes various computer-readable instruction sets by the CPU 52, thereby causing the timing determination unit 101, the notification control unit 102, and the reel control unit 103 illustrated in FIG. These functions and other functions can be realized.

  The timing determination unit 101 determines that the release timing for releasing the device 20 has arrived based on the moving direction of the device 20 to be cast. For example, the release timing is determined based on the angle θ with respect to the vertical direction V of the moving direction of the device 20 (the direction indicated by the arrow in FIG. 4).

  In one embodiment, the angle θ of the moving direction of the device 20 with respect to the vertical direction can be calculated by a known method based on the detection signal of the motion sensor 31 provided in the device 20. Specifically, by calculating the triaxial speed based on the triaxial acceleration of the device 20 output from the motion sensor 31 and calculating the inclination of the motion sensor 31, the moving direction of the device 20 with respect to the vertical direction is calculated. The angle θ can be obtained.

  In another embodiment, the angle θ of the moving direction of the device 20 with respect to the vertical direction is determined from the detected value of the motion sensor 32, the detected value of the tension sensor 33, the fishing rod characteristic value indicating the characteristics of the fishing rod 1, and the tip of the fishing rod 1 It can be calculated based on at least one of the length of the fishing line L up to 20 (running length) and the mass of the device 20. For example, the angle θ is calculated as follows. (1) Based on the detection signal of the motion sensor 32, the speed of the portion of the fishing rod 1 that is not elastically deformed is calculated. (2) Based on the tension of the fishing line L detected by the tension sensor 33, the displacement and speed of the tip with respect to the portion of the fishing rod 1 not elastically deformed are calculated. The displacement of the tip of the fishing rod 1 includes, for example, the characteristics of the fishing rod 1 (the axial length of the fishing rod 1, the mass matrix M (x), the stiffness matrix K (x), and the damping matrix C (x)) and the tension sensor. It can be calculated by the finite element method based on the tension of the fishing line L detected by 33. The tip speed can be calculated by differentiating the tip displacement with respect to time. The fishing rod characteristic value indicating the characteristics of the fishing rod is often displayed on the fishing rod 1. Therefore, when the casting support device 50 is attached to the fishing rod 1, the fishing rod characteristic value of the fishing rod 1 can be input to the casting support device 50. (3) The displacement and speed of the device 20 with respect to the tip of the fishing rod 1, the axial length of the fishing rod 1, the length of the fishing line L from the tip of the fishing rod 1 to the device 20, and the mass of the device 20, Using the tension of the fishing line L detected by the tension sensor 33, calculation is performed, for example, by the Runge-Kutta method. By combining the speed of the portion of the fishing rod 1 that is not elastically deformed, the speed of the tip for the portion of the fishing rod 1 that is not elastically deformed, and the speed of the device 20 for the tip, the three axes of the device 20 are calculated. Can be determined. Based on the triaxial speed of the device 20, the angle θ of the moving direction of the device 20 with respect to the vertical direction can be obtained.

  The process for calculating the moving direction of the device 20 described above is merely an example, and the method for calculating the moving direction of the device 20 applicable to the present invention is not limited to the one explicitly described in this specification. As long as it is not contrary to the gist of the present invention, the moving direction of the device 20 can be calculated by any method apparent to those skilled in the art.

  In one embodiment, the timing determination unit 101 is configured to determine that the release timing has arrived when the angle θ between the moving direction of the device 20 and the vertical direction has reached a predetermined release angle. When so-called overhead casting is performed, as shown in FIG. 5, the angle θ of the moving direction of the device 20 with respect to the vertical direction monotonously increases from the start of casting. FIG. 5 is a graph showing the relationship between the time during casting and the moving direction of the device. The horizontal axis shows the elapsed time from the start of casting, and the vertical axis shows the angle θ of the device 20 with respect to the vertical direction. Overhead casting is an aspect of casting in which a device is thrown by swinging a fishing rod along a vertical plane.

  The angle θ with respect to the vertical direction of the moving direction of the device 20 will be further described with reference to FIG. FIG. 6 is a diagram schematically illustrating the trajectory of the fishing rod and the trajectory of the device 20 that moves along with the fishing rod 1 when overhead casting is performed. FIGS. 6A to 6G show the posture of the fishing rod 1 from the start of casting to the release of the device 20 in time series. FIG. 6A shows the posture of the fishing rod 1 at the start of casting, and FIG. 6G shows the posture of the fishing rod 1 when the device 20 is released. As shown in FIG. 6 (a), at the start of casting, the fishing rod 1 is held by the angler in such a posture that the front in the axial direction faces the direction of approximately 9 o'clock. Therefore, immediately after the start of casting, the device 20 moves upward in the vertical direction in accordance with the movement of the fishing rod 1. At this time, since the mechanism 20 moves substantially along the vertical direction, the angle θ of the movement direction of the mechanism 20 with respect to the vertical direction takes a small value. In the section shown in FIGS. 6B to 6G, the device 20 gradually moves in the horizontal direction according to the posture of the fishing rod 1. Accordingly, in the section shown in FIGS. 6B to 6G, the angle θ of the moving direction of the device 20 with respect to the vertical direction gradually increases. Thus, the angle θ of the moving direction of the device 20 with respect to the vertical direction monotonously increases until the device 20 is released at time T1 with respect to the elapsed time from the start of casting. FIG. 5 shows that the angle θ of the moving direction of the device 20 with respect to the vertical direction reaches the release angle θ1 when the time from the start of casting is T1.

  This release angle is set to 45 degrees, for example. In consideration of air resistance, the release distance is larger than 45 degrees, for example, around 50 degrees, because the flying distance can be increased by releasing the device when the angle is larger than 45 degrees with respect to the vertical direction. May be set. In addition, considering that it is determined that the mechanism moving direction is at a predetermined angle, the release timing is notified to the angler, and then it takes time for the angler to actually perform the operation for release, The release angle may be set to an angle slightly smaller than 45 degrees, for example, around 40 degrees. This release angle can be appropriately set according to the angle of the angler's casting operation.

  With reference to FIG. 7, another aspect for determining that the release timing has arrived will be described. FIG. 7 is a graph showing the relationship between the time during casting and the moving speed of the device. The horizontal axis shows the elapsed time from the start of casting, and the vertical axis shows the speed (absolute value) of the device 20. In one embodiment, the timing determination unit 101 detects that the angle formed by the moving direction of the device 20 with respect to the vertical direction is within the release angle range, and detects that the speed of the device 20 has a maximum value. If so, the release timing is determined to have arrived. As described above, the angle θ between the moving direction of the device 20 and the vertical direction monotonously increases from the start of casting until the device 20 is released. The time T2 in FIG. 7 is the time when the angle θ between the moving direction of the device 20 and the vertical direction reaches the lower limit of the release angle range, and the time T3 is when the angle θ reaches the upper limit of the release angle range. Is the time. The lower limit of the release angle range is, for example, 40 degrees, and the upper limit is, for example, 50 degrees. The lower limit and the upper limit of the release angle range can be changed as appropriate.

  If the speed profile when casting the mechanism 20 is the profile indicated by VP1 in FIG. 7, the timing determination unit 101 reaches the lower limit of the release angle range at time T2, and then the speed of the mechanism 20 reaches the maximum value. It is determined that the release timing has arrived at time T4. When the timing determination unit 101 detects that the speed of the device 20 has decreased before the time T3 has elapsed after the time T2 has elapsed, the timing determination unit 101 determines that the release timing has arrived when the speed of the device 20 has decreased. May be. On the other hand, if the speed profile when casting the device 20 is the profile indicated by VP2 in FIG. 7, the timing determination unit 101 reaches the lower limit of the release angle range at time T2, and then the release angle range at time T3. Since the speed of the device 20 does not take the maximum value until the upper limit of the above is reached, it can be determined that the release timing has arrived at time T3.

  When the timing determination unit 101 determines that the release timing has arrived, the notification control unit 102 performs control for causing the notification unit 56 to perform notification. For example, when the timing determination unit 101 determines that the release timing has arrived, the notification control unit 102 transmits a drive signal to the notification unit 56 and emits at least one of sound, light, and vibration to the notification unit 56. Let me. The angler can know that the release timing has arrived by sensing at least one of the sound, light, and vibration generated by the notification unit 56.

  When the timing determination unit 101 determines that the release timing has arrived, the reel control unit 103 performs control for switching the clutch mechanism 42 to the OFF state. For example, a control signal (OFF signal) for switching the clutch mechanism 42 to the OFF state is transmitted from the CPU 52 to the clutch drive mechanism 42a. When receiving the OFF signal, the clutch drive mechanism 42a operates, for example, an electric actuator to switch the clutch mechanism 42 to the OFF state. Thus, according to the casting support apparatus 50 according to the embodiment of the present invention, when it is determined that the release timing has arrived, the clutch mechanism 42 is automatically turned off (without requiring an angler's operation). Can be switched to. Therefore, it is not necessary for the angler to perform an operation for turning off the clutch before starting casting.

  The present invention can also be applied to the case where the device 20 is thrown by side throw casting. Side throw casting is an aspect of casting in which a device is thrown by swinging a fishing rod along a horizontal plane. In order to determine an appropriate release timing in the side slow casting, it is necessary to set in the control unit 51 a direction that can be used as a reference direction, such as a vertical direction in overhead casting. The reference direction in the horizontal plane is set by operating the operation button 57 in a state where the front of the fishing rod 1 in the axial direction is directed toward the target landing point before the casting is performed. For example, the azimuth | direction which the fishing rod 1 faces can be acquired with a geomagnetic sensor, and this acquired azimuth | direction can be set as a reference direction (target direction) in a horizontal surface.

  In the embodiment in which the device 20 is thrown by side slow casting, the timing determination unit 101 calculates the angle φ of the moving direction of the device 20 in the horizontal plane with respect to the target direction, and the calculated angle φ is predetermined. It may be configured to determine that the release timing has arrived when the release angle is reached. The angle φ in the moving direction of the device 20 monotonously decreases from the start of casting, and becomes 0 when the moving direction of the device 20 matches the target direction. Therefore, the release angle for the angle φ is set to approximately 0 degrees. Considering that it takes time for the angler to be notified of the release timing and then the angler to actually perform the release operation, the release angle is set to a slightly larger angle than 0 degrees, for example, around 10 degrees. May be. This release angle can also be appropriately set according to the angle of the angler's casting operation.

  The angle φ of the moving direction of the device 20 in the horizontal plane with respect to the target direction can be calculated by the same method as the method for calculating the angle θ described above. The timing determination unit 101 determines that the angle formed by the moving direction of the device 20 in the horizontal plane with respect to the target direction is within the release angle range, and detects that the speed of the device 20 exhibits a maximum value. In this case, it may be configured to determine that the release timing has arrived.

  The swing surface through which the fishing rod passes during casting may have a predetermined angle with respect to the vertical direction and the horizontal direction, respectively. Casting that swings a fishing rod along a plane inclined with respect to both the vertical direction and the horizontal direction is sometimes referred to as “sleek alter casting”. The present invention can also be applied to the case where the device 20 is thrown by leak alter casting. In the embodiment in which the mechanism 20 is thrown by the leak alter casting, the timing determination unit 101 combines the above-described determination method in overhead casting and the determination method in side slow casting as needed, or releases timing using one of them. Can be determined.

  The dimensions, materials, shapes, and arrangements of each component described herein are not limited to those explicitly described in the embodiments, but rather are any dimensions that can be included within the scope of the present invention, Each component can be modified to have material, shape, and arrangement. In addition, components other than those explicitly described in the present specification can be added to the described embodiments, and some of the components described in the embodiments can be omitted.

  For example, some or all of the components of the casting support apparatus 50 may be provided in addition to the reel R. For example, the notification unit 56 may be provided on the outer surface (for example, near the grip) of the rod body of the fishing rod 1. In particular, when the notification unit 56 is an actuator that performs notification by vibration, the actuator can be provided on the grip of the fishing rod 1.
