The present disclosure relates to a fishing reel.
Communication methods that are configured to automatically carry out Near Field wireless Communication (NFC), when one electronic device enters a field in which it is possible to communicate with another electronic device, are known from the prior art (for example, refer to Japanese published unexamined application 2015-76775 Official Notice).
Fishing reels in which braking parameter settings can be changed using an electronic device external to the reel are known (for example, refer to Japanese Patent No. 71,66,895).
It has been determined that there is a need to restrict or avoid an increase in the size of a fishing reel such as the reels disclosed in Japanese published unexamined application 2015-76775 Official Notice and Japanese Patent No. 7,166,895, even if a communication unit that can improve communication efficiency, such as an antenna, is provided.
The present disclosure was conceived in light of these circumstances, and an object thereof is to provide a fishing reel in which it is possible to install a communication unit that can improve communication efficiency, such as an antenna, while restricting or avoiding an increase in the size of the reel.
A first aspect of a fishing reel according to the present disclosure comprises: a reel body; an electronic circuit unit provided in the reel body; a communication unit that can communicate with an external electronic device; and a shielding part that is provided between the electronic circuit unit and the communication unit and magnetically shields the electronic circuit unit from the communication unit.
By the first aspect of the fishing reel according to the present disclosure, a shielding part is disposed between the communication unit and the electronic circuit unit. The shielding part can suppress the magnetic effect of magnets, circuit boards, etc., that are received by the communication unit from the electronic circuit unit, thereby establishing good communication with electronic devices. Moreover, the inductor value in the communication unit can be adjusted and the communication range can be increased.
In addition, it is possible to reduce the thickness and size of fishing reels equipped with a communication unit, by simply providing a shielding part.
A second aspect of the present disclosure is the fishing reel according to the first aspect, wherein the shielding part is preferably a magnetic sheet.
In this case, since a thin magnetic sheet can be disposed, the thickness and size of the fishing reel can be further reduced.
A third aspect of the present disclosure is the fishing reel according to the first aspect, wherein the shielding part preferably has a magnetic sheet and/or a copper foil, in accordance with the magnitude of the inductor value.
In this case, for example, if the inductor value is small, a magnetic sheet can be disposed as an adjustment to increase the inductor value. If the inductor value is large, a copper foil can be disposed as an adjustment to reduce the inductor value.
A fourth aspect of the present disclosure is the fishing reel according to any one of the first to the fourth aspects, wherein the electronic circuit unit can have a storage unit that stores setting information, and a control unit that causes the communication unit and the electronic device to communicate when the communication unit and the electronic device enter a field in which Near Field wireless Communication is possible, and that updates the setting information of the storage control unit.
In this case, if an electronic device such as a smartphone is brought close to a portion of a fishing reel in which a communication unit is incorporated, Near Field wireless Communication is automatically performed between the communication unit and the electronic device, the electronic device can receive supply of power, and the communication unit can receive setting information of the electronic device. The setting information received by the communication unit can be communicated with the electronic circuit unit. In this case as well, because a shielding part is disposed between the communication unit and the electronic circuit unit, it is possible to suppress the electrical impact that the electronic circuit unit has on the Near Field wireless Communication, thereby establishing good communication.
A fifth aspect of the present disclosure is the fishing reel according to any one of the first to the fourth aspects, wherein the communication unit can be an antenna substrate on which a pattern coil is disposed, and the shielding part can be disposed on a surface of the antenna substrate facing the electronic circuit unit.
In this case, it is possible to easily form a pattern coil by printing conductive paint, for example, on the substrate. Even when such an antenna substrate is employed, a shielding part can be disposed between the antenna substrate and the electronic circuit unit to adjust the inductor value to be larger.
A sixth aspect of the present disclosure is the fishing reel according to any one of the first to the fifth aspects, wherein the electronic circuit unit can include a braking part that controls the braking force of a spool, and the shielding part can magnetically shield the braking part from the communication unit.
In this case, because the communication unit is shielded from the magnetism of the braking magnet, it is possible to prevent the communication between the communication unit and the electronic device from being affected by magnetism. As a result, it is possible to prevent deterioration in the communication accuracy in the communication unit.
By the fishing reel according to the present disclosure, it is possible to provide a communication unit that can improve communication efficiency, such as an antenna, while restricting or avoiding an increase in the size of the reel.
An embodiment of the fishing reel according to the present disclosure will be described below with reference to the drawings. In each of the drawings, there are cases in which the scale of each component has been appropriately changed as required to improve the visibility of the component.

The control unit 42B can include, for example, a transmission unit. In this case, the control unit 42B can output, as transmission data from the transmission unit, to an output unit (not shown) disposed in the reel body 1. For example, the output unit is a unit that presents images, sounds, vibrations, etc., to the user of the dual bearing reel 100, such as a speaker or a display function unit, such as a liquid crystal display, that can be viewed by the angler.
The action of the dual bearing reel 100 configured in this manner will be described in detail next, based on the drawings.
The dual bearing reel 100 according to the present embodiment comprises: the reel body 1; the circuit board 31 disposed in the reel body 1; the antenna unit 41 that can communicate with the external terminal device 70; and the shielding sheet 46 that is disposed between the circuit board 31 and the antenna unit 41 and magnetically shields the circuit board 31 from the antenna unit 41.
In the dual bearing reel 100 according to the present embodiment, the shielding sheet 46 is disposed between the antenna unit 41 and the circuit board 31 to suppress the magnetic effect of magnets, circuit boards, etc., that the antenna unit 41 receives from the circuit board 31, thereby enabling good communication with the terminal device 70. Moreover, the inductor value in the antenna unit 41 can be adjusted and the communication range can be increased.
In addition, by the present embodiment, it is possible to reduce the thickness and size of the dual bearing reel 100 equipped with the antenna unit 41, by simply providing the shielding sheet 46.
Additionally, in the present embodiment, since the shielding sheet 46 is a magnetic sheet, the thickness and size of the dual bearing reel 100 can be further reduced.
In addition, in the present embodiment, the shielding sheet 46 has a magnetic sheet and/or a copper foil of the shielding sheet 46, in accordance with the magnitude of the inductor value.
As a result, for example, if the inductor value is small, a magnetic sheet can be disposed as an adjustment to increase the inductor value. If the inductor value is large, a copper foil can be disposed as an adjustment to reduce the inductor value.
In addition, in the present embodiment, the circuit board 31 comprises the storage unit 42A that stores setting information, and the control unit 42B that causes the antenna unit 41 and the terminal device 70 to communicate when the antenna unit 41 and the terminal device 70 enter a field in which Near Field wireless Communication is possible, and updates the setting information of the storage unit 42A.
As a result, if the terminal device 70 such as a smartphone is brought close to a portion (left side plate 1B) of the dual bearing reel 100 in which the antenna unit 41 is incorporated, Near Field wireless Communication is automatically performed between the antenna unit 41 and the terminal device 70, the electronic device can receive supply of power, and the antenna unit 41 can receive setting information of the terminal device 70. The setting information received by the antenna unit 41 can be communicated with the circuit board 31. In this case as well, because the shielding sheet 46 is disposed between the antenna unit 41 and the circuit board 31, it is possible to suppress the electrical impact that the circuit board 31 has on the Near Field wireless Communication, thereby enabling good communication.
In addition, in the present embodiment, the antenna unit 41 is the antenna substrate 43 on which the pattern coil 432 is formed. The shielding sheet 46 is arranged on a surface of the antenna substrate 43 facing the circuit board 31.
It is thereby possible to easily form the pattern coil 432 by printing conductive paint, for example, on the substrate body 431. Even when such an antenna substrate 43 is employed, the shielding sheet 46 can be disposed between the antenna substrate 43 and the circuit board 31 to adjust the inductor value to be larger.
Additionally, in the present embodiment, the circuit board 31 includes the braking part 30 that controls the braking force of the spool 5. The shielding sheet 46 magnetically shields the braking part 30 from the antenna unit 41.
As a result, because the magnetism of the braking magnet is shielded from the antenna unit 41, it is possible to prevent the communication between the antenna unit 41 and the terminal device 70 from being affected by magnetism. As a result, it is possible to prevent deterioration in the communication accuracy in the antenna unit 41.
By the dual bearing reel 100 according to the present embodiment configured as described above, it is possible to install the antenna unit 41 that can improve communication efficiency while restricting or avoiding an increase in the size of the reel.
Another embodiment of the fishing reel according to the present disclosure will be described next. Compositional elements that have the same functions as the compositional elements of the above-described first embodiment are given the same codes and detailed descriptions thereof are omitted to avoid redundant descriptions.
As shown in
The air core coil 45 is wound in an annular shape along the circular through-hole 31c on the front surface 31a of the circuit board 31. The air core coil 45 is disposed so as not to protrude in the radially inward direction of the through-hole 31c of the circuit board 31. The air core coil 45 has an overall cross-sectional diameter of, for example, 1.7-2.0 mm, and the number of turns of the annular winding is set to about 15 turns.
Any appropriate method, such as normal winding or a-winding, can be employed as the method of winding the enameled wire in the air core coil 45.
In the second embodiment, since the air core coil 45 is simply disposed on the existing circuit board 31, assembly of the air core coil 45 can be easily carried out. It is a particularly effective structure if there is space in the height direction (left-right direction) above the circuit board 31.
The above-described embodiment of the fishing reel according to the disclosure is presented as an example and is not intended to limit the scope of the disclosure. The embodiments can be implemented in a variety of other forms; furthermore, various omissions, substitutions and changes can be made without departing from the essence of the disclosure. Embodiments include those that can be easily conceived of by a person skilled in the art, those that are substantially the same, and those that are of equivalent scope.
For example, the configuration and the position where a communication unit, such as the antenna unit 41, is disposed in the reel body 1 are not limited to the embodiments described above. For example, the position is not limited to the left side plate 1B on the opposite side of the handle 2, which is provided on the right side plate 1A, as described above. That is, the communication unit can be provided at positions such as an inner layer of the substrate, on one side of the substrate, between the substrate and a case (side plates 1A, 1B of the reel body 1), in the case itself, or on the outer side of the case.
Additionally, in the present embodiment, the shielding sheet 46 made of a magnetic sheet is employed as the shielding part, but no limitation is imposed by such a sheet-like configuration; shielding parts having other shapes can be used. In short, it suffices if the shielding part is provided between an electronic circuit unit and a communication unit and magnetically shields the electronic circuit unit from the communication unit.
In addition, in the present embodiment, the electronic circuit unit (circuit board 31) is configured to comprise the storage unit 42A and the control unit 42B, but no limitation is imposed thereby.
In addition, configurations such as the sizes and shapes of the reel body 1, the spool 5, the handle 2, the brake unit 3, and the like, can be changed as appropriate.
