Description

[Technical Field]

[0001] The present invention relates to a fishing reel having a braking unit that brakes a spool rotatably attached to a reel body. [Background technology]

[0002] Conventionally, dual-bearing reels, particularly bait-casting reels that use a fishing line with a lure or other rig attached to the end for casting, have been provided with a braking means for braking the spool to prevent backlash during casting.

[0003] As an example of a fishing reel equipped with such a braking means, Patent Document 1 discloses a fishing reel with an electrically controllable braking means to suppress backlash during casting. In the fishing reel of Patent Document 1, a permanent magnet provided on the spool and a coil provided on the stator generate electricity when the spool rotates at high speed, and the induced electromotive force generated there is converted to direct current and voltage stabilized by a rectifier circuit, and the power is supplied to a storage element to drive a control board and appropriately control the conduction state of the coil, thereby realizing the application of an appropriate braking force to the spool.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-208630 Summary of the Invention [Problem to be solved by the invention]

[0005] Conventional fishing reels, including those described in Patent Document 1, are equipped with a detection unit, such as a spool rotation detection sensor, to detect reel status, such as line length and winding speed. The detected reel status can be saved as a log or communicated with an external device, such as a smartphone, improving user convenience. However, the fishing reel described in Patent Document 1 cannot supply power to the control board when the spool rotation speed is below a predetermined value (when the spool is stopped or at a low speed). This makes it difficult to save the reel status or communicate with the outside world when the spool is rotating at a low speed. Furthermore, if a method of supplying power to the control board using a battery is used to achieve these functions, there is also the problem that the functions cannot be realized when the battery runs out.

[0006] The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a fishing reel having a braking unit that applies a braking force to the spool, which allows the reel status log to be saved and retrieved externally without using a battery. Other objects of the present invention will become apparent by reading the entire specification. [Means for solving the problem]

[0008] In a fishing reel according to one embodiment of the present invention, the control unit is configured to intermittently switch the braking unit between braking and non-braking states depending on the reel state of the fishing reel when the spool rotates in the release direction, and to switch the braking unit to a constant braking state when the spool rotates in the reeling direction.

[0009] A fishing reel according to one embodiment of the present invention includes a power generation unit capable of generating electricity in response to braking by the braking unit, and the control unit has a log storage mode that stores the reel status of the fishing reel and an external communication mode that communicates the stored information to the outside, and is configured to operate and drive the control unit with power generated by the power generation unit in the storage mode, and to operate and drive the control unit with power received by the external power receiving unit in the communication mode.

[0010] In a fishing reel according to one embodiment of the present invention, the power generating unit is configured to generate electricity through interaction between the coil and the spool.

[0011] A fishing reel according to one embodiment of the present invention is configured to include a spool rotatably supported on a reel body of the fishing reel, a braking unit that applies a braking force to the spool through the interaction between a permanent magnet attached to the spool and a coil attached to the reel body, a control unit that controls the braking unit, a detection unit that detects the state of the fishing reel, and a storage unit that is removable from the fishing reel and stores information obtained by the detection unit. [Effects of the Invention]

[0012] According to the above embodiment, it is possible to provide a fishing reel that has a braking unit that applies a braking force to the spool, and that can store a log of the reel status and retrieve data externally without having to store a battery inside.

[0014] Hereinafter, an embodiment of a fishing reel according to the present invention will be described in detail with reference to the accompanying drawings. Components common to multiple drawings are designated by the same reference numerals throughout the drawings. Please note that the drawings are not necessarily drawn to scale for ease of explanation.

[0015] A fishing reel according to one embodiment of the present invention will be described with reference to Figures 1 to 3. Figures 1(a), (b), (c), and (d) are system diagrams showing the electrical functional configuration of a fishing reel 1 according to one embodiment of the present invention.

[0016] First, the component configuration of a fishing reel 1 according to one embodiment of the present invention will be described using Figure 1. As shown in the figure, the fishing reel 1 according to one embodiment of the present invention is configured to include a frame (reel body) 2, a spool 3, a braking section (braking means) 4, a control section (control means) 5, a detection section (detection means or sensor section) 6, and an external power receiving section 15, but may also include a power generating section 8, a power source selecting section 9, and other components.

[0017] The frame (reel body) 2 is configured to be attachable to a fishing rod (not shown). Like conventional fishing reels, the fishing reel 1 according to one embodiment of the present invention has an operating unit or operating means (e.g., a handle) (not shown), which can be operated by a user to rotate the spool 3 in the forward direction and reel in the fishing line. The rotation of the operating unit or operating means (hereinafter referred to as the operating unit) is transmitted to the spool 3 by a transmission means such as a gear (not shown).

[0018] Furthermore, the fishing reel 1 according to one embodiment of the present invention has a clutch unit (clutch means) (not shown), and a user can select whether to connect or disconnect power transmission to the spool 3 by operating the clutch unit (clutch means). When power transmission to the spool 3 is connected, winding of the line is possible using the operating unit. On the other hand, when power transmission to the spool 3 is disconnected, the spool can be freely rotated in both forward and reverse directions, allowing the fishing line to be released.

[0019] The fishing reel 1 according to one embodiment of the present invention may also be provided with a drag unit or drag means (not shown) that prevents the fishing line from breaking by causing the spool 3 to spin freely when torque equal to or greater than a predetermined value is generated, and a reverse rotation prevention unit or reverse rotation prevention means (not shown) that prevents the operating unit from rotating in the reverse direction. Furthermore, the fishing reel 1 may also be provided with an oscillator device (not shown) that evenly winds the fishing line by reciprocating the position of a fishing line guide that guides the fishing line in accordance with the rotation of the spool 3.

[0020] The spool 3 is supported on the reel body 2 so as to be rotatable relative to the reel body 2. When the spool 3 rotates in the forward direction, the fishing line can be wound around the outer periphery of the spool 3. On the other hand, when casting a lure or the like, the spool 3 rotates in the reverse direction, allowing the wound fishing line to be released. In this case, if the amount of fishing line released is greater than the amount of movement of the lure or the like, the excess fishing line can cause line tangles known as backlash, which can interfere with normal use of the fishing reel 1. For this reason, such backlash is prevented by applying an appropriate braking force to the spool 3 using the brake unit 4, which will be described later.

[0021] Next, we will explain the braking unit 4. The braking unit 4 is composed of a permanent magnet 41 provided on the spool 3, a coil 42 held integrally with the frame 2, and a switch element 43 provided in the control unit 5.

[0022] The permanent magnet 41 is formed in a roughly cylindrical shape coaxial with the rotation axis of the spool 3, and its outer periphery is divided into n equal parts and magnetized with alternating north and south poles. The coil 42 is wound in a roughly rectangular shape so that the wound core wire faces the permanent magnet 41 and is positioned within the magnetic field of the magnet 41. When multiple coils 42 are arranged, the coils are electrically connected in series or parallel, and both ends of the coils are connected to the switch element 43.

[0023] The switch element 43 is configured, for example, by two parallel-connected field effect transistors (FETs) that can be turned on and off at high speed, and can select electrical connection / disconnection of the coil .

[0024] This configuration makes it possible to apply braking to the spool 3 using so-called dynamic braking. That is, as the spool 3 rotates at high speed, the magnetic field generated by the permanent magnet 41 moves relative to the coil 42. When the coil 42 is electrically connected by the switch element 43 at this time, an electromotive force is generated in the coil 42. This electromotive force generates a current in the circuit formed by the coil 42, which generates a magnetic force in the permanent magnet 41 acting in the direction opposite to the direction of rotation. This generates a braking torque in the spool 3 that is proportional to the square of the rotation speed. Furthermore, when the coil 42 is electrically disconnected by the switch element 43, the generation of this braking torque can be stopped.

[0025] By appropriately switching between connection and disconnection of the switch element 43, a predetermined braking torque can be generated in the spool 3. While braking torque is being generated in the spool 3, the mechanical energy of the spool 3 is converted into electrical energy in the circuit formed by the coil 42.

[0026] In this specification, such a conversion means is referred to as a power generation unit (power generation means or power generation mechanism) 8 or a spool power generation unit 8. Here, the power generation unit 8 is composed of a permanent magnet 41, a coil 42, a switch element 43, a rectifier circuit, and a power storage element, but may include components other than these. The power generation unit 8 generates electrical energy, and the generated electrical energy is supplied to the control unit 5 to operate and drive the control unit 5. In this specification, the power generation produced by the power generation unit 8 is referred to as spool power generation. Note that a yoke made of a ferromagnetic material such as iron may be disposed around the outer periphery of the coil 42 to efficiently generate a magnetic field from the permanent magnet 41 in the coil 42.

[0027] Next, the control unit 5 controls the braking unit 4 to apply appropriate braking to the spool 3. The control unit 5 includes a ROM storing a predetermined program, a memory unit (RAM) that temporarily stores detection information and the like during program processing, a CPU that controls these, a storage unit (storage unit or storage means) 11 such as a flash ROM that can store data even after power is turned off, and a communication unit (communication means) 12 that communicates with the outside world via wireless communication using wireless communication network technology or wired communication via a USB connector or the like. Each of these components is located within a single semiconductor component or on a board with an electrical circuit printed on it. The control unit 5 can also be configured to include a display / output unit (display / output means) such as an LED, LCD, or buzzer.

[0028] The CPU (not shown) of the control unit 5 is configured to acquire detection information from the detection unit 6 that detects the state of the fishing reel. The detection unit 6 may include, for example, a spool rotation detection unit or means 61 that detects the rotation state of the spool, a handle rotation detection unit or means 62 that detects the rotation state of the handle, a clutch detection unit or means 63 that detects the engaged / disengaged state of the clutch, a tension detection unit or means 64 that detects the tension of the fishing line, a set drag force detection unit or means 65 that detects the set drag force, a motion sensor 66 that detects the movement of the fishing reel and fishing rod, a braking force detection unit 67 that detects the braking force in the braking unit 4, etc., but the control unit 5 may be configured to include some or all of these.

[0029] The spool rotation detector 61 can detect whether the spool is rotating or not by an electrical signal generated when a detectable part, such as a magnet, provided on the spool approaches a detector, such as a coil, provided on the reel body (frame). As the detection means, a conventionally known method such as a photosensor or magnetic sensor can be used, and an appropriate detectable part can be provided on the spool depending on the detection means.

[0030] The handle rotation detector 62 can be implemented by attaching a rotation sensor to the handle or a gear that rotates in conjunction with the handle. It can be implemented by known means, such as an incremental rotation sensor that uses a photointerrupter or a magnetic sensor. A non-contact rotation sensor is desirable to ensure smooth handle rotation. By calculating the difference between the handle rotation detector 62 and the spool rotation detector 61, the amount of rotation idling caused by the drag device can be calculated.

[0031] The clutch detection means 63 can detect whether the fishing line can be released from the spool by attaching a limit switch or other sensor to a part of the clutch operating member. The tension detection unit 64 can be realized by various conventionally known technologies, such as using a strain sensor to detect the force acting on the rotation axis of the pulley that guides the fishing line.

[0032] The set drag force detection unit 65 detects the set tension that is the threshold at which the spool spins freely. This can be achieved by detecting the charging force acting on the friction member in the drag device using a pressure sensor or the like.

[0033] The motion sensor 66 can detect the movement of the fishing rod or reel. This can be achieved by using a gyro sensor, a conventionally known technology, such as a method of detecting frequency changes in a vibrating piezoelectric element. By using a sensor called a nine-axis motion sensor that detects the direction, acceleration, and angular velocity of each of three orthogonal axes, the sensor can function as a direction detector, acceleration detector, and angular velocity detector. The set braking force detector 67 can detect the set value of the braking force for suppressing backlash.

[0034] The control unit 5 can generate a predetermined braking torque on the spool 3 by appropriately switching between connection and disconnection of the switch element 43 at known switching timing in accordance with the detection result of the above-mentioned detection unit 6. This can increase the casting distance of a lure or the like while avoiding the occurrence of backlash.

[0035] This sequence of appropriately controlling the braking unit 4 by the control unit 5 is referred to as the cast braking mode. Various known braking methods can be used in the cast braking mode, and detailed explanations will be omitted here.

[0036] A fishing reel 1 according to one embodiment of the present invention is configured to include a spool 3 rotatably supported on a reel body 2 of the fishing reel 1, a braking unit 4 that applies a braking force to the spool 3 through the interaction between a permanent magnet 41 attached to the spool 3 and a coil 42 attached to the reel body 2, a control unit 5 that controls the braking unit 4, a detection unit 6 that detects the state of the fishing reel 1, a storage unit 11 that stores information acquired by the detection unit 6, a communication unit 12 that transmits the information stored in the storage unit 11, and an external power receiving unit 15 that can receive power from an external source.

[0037] According to a fishing reel 1 of one embodiment of the present invention, it is possible to provide a fishing reel 1 that has a braking unit 4 that applies a braking force to a spool 3, and that can store a log of the reel status and retrieve data externally without having an internal battery. Specifically, for example, it is possible to store the change in line length while fishing and check that information on an external device such as a smartphone.

[0038] In the fishing reel 1 according to one embodiment of the present invention, the control unit 5 is configured to intermittently switch the braking unit 4 between braking and non-braking states depending on the reel state of the fishing reel 1 when the spool 3 rotates in the release direction, and to switch the braking unit 4 to a constant braking state when the spool 3 rotates in the reel-up direction. In this way, by applying an appropriate braking force to the braking unit during casting, it is possible to avoid backlash and increase the casting distance of a lure or the like. Furthermore, it is possible to ensure the amount of power generated by the power generator 8 during reel-up.

[0039] A fishing reel 1 according to one embodiment of the present invention includes a power generation unit 8 capable of generating electricity in response to braking of the brake unit 3, and a control unit 5 having a log storage mode for storing the reel status of the fishing reel 1 and an external communication mode for communicating the stored information to an external device. In the storage mode, the control unit 5 is operated and driven by the power generated by the power generation unit 8, and in the communication mode, the control unit 5 is operated and driven by the power received by the external power receiving unit 15. In this way, the reel status can be stored in the log storage mode when the spool rotation speed is equal to or greater than a predetermined value, without using a battery as a component of the fishing reel. Furthermore, data stored in the reel can be read using external power.

[0040] In the fishing reel 1 according to one embodiment of the present invention, the power generating unit 8 is configured to generate electricity through the interaction between the coil 42 and the spool 3. In this way, it is possible to generate electricity for driving the control unit using the kinetic energy generated when the spool 3 rotates.

[0041] A fishing reel 1 according to one embodiment of the present invention is configured to include a spool 3 rotatably supported on a reel body 2 of the fishing reel 1, a braking unit 4 that applies a braking force to the spool 3 through the interaction between a permanent magnet 41 attached to the spool 3 and a coil 42 attached to the reel body 2, a control unit 5 that controls the braking unit 4, a detection unit 6 that detects the state of the fishing reel 1, and a storage unit 21 that is removable from the fishing reel 1 and that stores information acquired by the detection unit 6.

[0042] According to a fishing reel 1 of one embodiment of the present invention, it is possible to provide a fishing reel 1 that has a braking unit 4 that applies a braking force to a spool 3, and that can store a log of the reel status and retrieve data externally without having an internal battery. Specifically, for example, it is possible to store the change in line length while fishing and check that information on an external device such as a smartphone.

[0043] Next, a reel state log saving mode in a fishing reel 1 according to one embodiment of the present invention will be described with reference to Figure 2. As described above, in a fishing reel 1 according to one embodiment of the present invention, while the braking unit 4 is generating a braking force on the spool 3, the kinetic energy of the spool 3 can be converted into electrical energy in the circuit created by the coil 41. This electrical energy can be used to drive the control unit 5 and the detection unit 6. When the number of rotations of the spool 3 exceeds a predetermined value during casting or high-speed handle rotation, for example, and the amount of power generated by the power generation unit (spool power generation unit) 8 exceeds a predetermined value, the control unit 5 and the detection unit 6 can be activated or driven.

[0044] Note that if the control unit 5 is operated or driven intermittently or if the rotation speed of the spool 3 fluctuates, the power generated by the power generation unit 8 may also fluctuate. However, by smoothing out these fluctuations using a power storage element, the control unit 5 and the detection unit 6 can be driven stably. Note that the threshold at which the amount of power generated by the power generation unit 8 can activate or drive the control unit 5 and the detection unit 6 is determined by the power generation efficiency of the power generation unit 8. Possible means for increasing the power generation efficiency include increasing the volume of the permanent magnet 41, using a material with a high magnetic flux density, increasing the number of turns of the coil 42, or increasing the diameter of the winding. Also, the threshold can be reduced by reducing the power consumption of the control unit 5 and the detection unit 6.

[0045] When the generated or stored power exceeds a predetermined value, the control unit 5 is activated, and the log storage mode is initiated (step A1). The initiation process also includes activating the detection unit and initializing the memory. At predetermined times (e.g., every time a certain period of time has elapsed or when the change in the rotation speed of the spool 3 exceeds a predetermined value) (step A2), the control unit 5 acquires the reel status, such as the rotation speed of the spool 3, using the reel status detection unit of the fishing reel 1 (step A3). If necessary, the acquired information may be calculated, and a timestamp may be acquired simultaneously. The results are temporarily stored in RAM as necessary, and then stored in the storage unit (storage unit or storage means) 11. The data may be stored in the storage unit 11 sequentially, or may be stored collectively during the termination process described below.

[0046] Next, it is determined whether the power generated by the power generation unit 8 is equal to or greater than a predetermined value (Step A4). When the number of rotations of the spool 3 falls below a predetermined value, such as when the casting is completed or when the handle rotation is temporarily stopped, the amount of power generated by the power generation unit 8 falls below the power required to operate the control unit 5 and the detection unit 6. If the power stored in the power storage element is subsequently depleted, the control unit 5 and the detection unit 6 will become inoperable. Therefore, the control unit 5 may perform termination processing as necessary before they become inoperable or inoperable (Step A5). Termination processing may include, for example, saving unsaved data and a termination timestamp in the storage unit 11, disconnecting the reel state detection unit of the fishing reel 1, transmitting a termination event to an external device via the communication unit 12, and releasing temporary memory used for calculations, etc.

[0047] This makes it possible to save changes in the reel state over time. That is, it is possible to grasp in detail the changes in the number of rotations of the spool 3 over time during casting, and to record changes in the line length and winding speed when retrieving the lure.

[0048] Furthermore, when reeling in the fishing line, the switch element 43 is connected to switch the brake unit 4 to a constant braking state, thereby increasing the amount of power generated by the power generator 8. While this increases the operating torque required when the user operates the handle, it increases the amount of power stored in the power storage element and extends the time for which the control unit 5 and the detection unit 6 are driven. The detection unit 6, which detects the reel state, detects the rotation direction of the spool 3. If the rotation speed in the release direction exceeds a predetermined value, a braking sequence to prevent backlash is executed, and the switch element 43 is intermittently driven as necessary. If the rotation direction of the spool 3 is the reeling direction, the brake unit 4 is constantly in a braking state, ensuring sufficient power generation by the power generator 8. The log save mode may be executed simultaneously with the cast braking mode when casting a lure, etc. Furthermore, when the rotation speed of the spool 3 is in the reeling direction, the risk of backlash is low and there is little need to execute the cast braking mode, so only the log save mode may be executed.

[0049] Next, with reference to Figure 3, an external transmission mode of stored data in a fishing reel 1 according to one embodiment of the present invention will be described. Specifically, this relates to an external transmission mode in which data on the state of the reel stored in the storage unit is transmitted to an external device. The control unit 5 in a fishing reel 1 according to one embodiment of the present invention can receive power from an external source via an external power receiver 15. The external power receiver 15 can be, but is not limited to, a power receiving coil capable of receiving power wirelessly via radio waves, or a wired connector such as a USB connector capable of receiving power via a wired power supply.

[0050] When the external power receiving unit 15 receives power from an external source, it can activate or drive the control unit regardless of the rotation speed of the spool 3. This triggers the control unit to enter external transmission mode (step B1), or when a specific command is received after the external power supply. The start process includes pairing with the transmission destination and memory initialization. In external transmission mode, the reel status log data (data) stored in the storage unit 11 (storage in the illustrated example) is acquired (step B2), and the log data (data) is transmitted to an external device via the communication unit 12 (step B3). After transmitting one section of data, such as after each cast, the next data is transmitted as needed (step B4). When there is no more data to transmit, the external transmission mode process ends (step B5).

[0051] Possible external devices include, but are not limited to, information and communication terminals such as PCs (personal computers) and smartphones, cloud devices or systems, other reels or fish finders equipped with communication means, etc. This allows the time-varying state of the reel to be shared with external devices, thereby improving user convenience. The mode of communication by the communication unit 12 can be selected depending on the type of external device and the timing of communication. For example, when communicating with a smartphone carried by the user while fishing, wireless communication (which may include wireless power supply) can be used to prevent water droplets or foreign objects from getting into the connector.

[0052] One way to achieve this is by using short-distance wireless communication such as NFC. In short-distance wireless communication, the external power receiving unit 15 that receives power supply from the outside and the communication unit 12 (for example, a coil) that transmits data to the outside can be shared. Also, by using the start of external power supply when a data destination device comes close as a trigger for starting the mode, pairing operations and commands to start the external transmission mode can be omitted, thereby improving user convenience.

[0053] When communicating with a PC at home after a fishing trip or when communicating with assembly equipment at the factory, using a wired power supply means or wired communication means can increase the number of devices that can communicate and avoid problems such as crosstalk that can occur when pairing with the communication target.

[0054] If external power supply is possible while fishing, such as when a portable wireless power supply means is held close at hand, the log storage mode may be used while power is being supplied from an external power source. In this case, switching between the log storage mode and the external transmission mode may be performed by sending a command.

[0055] Furthermore, when the power consumption required for the external transmission mode is small, the power generated by the power generation unit 8 is large, and sufficient power can be stored in the power storage element, the external transmission mode may be used without external power feeding. This will increase the size of the power storage element, but will eliminate the need for an external power supply, making it possible to omit or miniaturize the external power receiving unit 15.

[0056] Here, the technical effects of the fishing reel 1 according to one embodiment of the present invention will be described. The fishing reel 1 according to one embodiment of the present invention can record a log of the reel status during fishing using power generated by the power generator, without using a battery as a component of the fishing reel. This eliminates the need for the user to perform tasks such as battery replacement, charging, and power on / off, improving convenience. Furthermore, by eliminating the need for a battery, the fishing reel as a whole can be made smaller, lighter, and less expensive, its waterproof structure can be simplified, and its lifespan can be extended. In addition, the configuration prevents the battery from running out, and log data can be recorded whenever the spool rotation speed reaches a predetermined value or higher. This improves the reliability of log data storage.

[0057] The saved log data of the reel status can be sent to an external device when powered by an external source, which means that there is no need to use a battery in the fishing reel itself when sending log information to an external device.

[0058] Next, a fishing reel 1 according to another embodiment of the present invention will be described with reference to Fig. 4. Note that a description of the same parts as those of the fishing reel 1 according to one embodiment of the present invention described with reference to Fig. 1 will be omitted.

[0059] Similar to the embodiment described above, the control unit 15 can be configured to include a ROM storing a predetermined program, a memory unit (RAM) that temporarily stores detection information and the like during program processing, and a CPU that controls these. The control unit 15 also includes a storage unit (storage unit or storage means) 21 such as a flash ROM that can store data even after power is turned off. However, the storage unit 21 in this embodiment is a removable storage means (removable media) such as a memory card, and by replacing the storage unit 21 with an external device, it becomes possible to supply power from the external device and read data to the external device. Furthermore, the communication unit that communicates with the outside and the external power receiving unit are not essential components of the control unit 15 in this embodiment and may be omitted.

[0060] Next, a log storage mode for acquiring a log of the reel state in this embodiment will be described. In this embodiment, as in the previous embodiment, a log of changes in the reel state over time can be stored in the storage unit 21 using the power generated by the power generation unit 8. In other words, the log storage mode in the previous embodiment can be implemented, and the same effects can be achieved.

[0061] Next, a method for reading the reel state log data stored in the storage unit 21 to an external device in this embodiment will be described. As described above, by replacing the storage unit 21 in this embodiment with an external device, it becomes possible to supply power to the storage unit 21 from the external device and read the log data to the external device. This makes it possible to store information (data) on changes in the reel state over time in the external device, improving user convenience. That is, in this embodiment, by replacing the storage unit 21 with an external device and reading the log data to the external device, it is possible to achieve the same effect as the external transmission mode in the above-described embodiment.

[0062] Compared to the methods in the previously described embodiments, the method in this embodiment requires the effort of replacing the storage unit with an external device after saving the data, but it makes it possible to omit the external power supply receiving unit, power supply selecting unit, and communication unit from the control unit, resulting in a simpler configuration, which makes it possible to make the entire reel smaller, lighter, and less expensive.

[0063] The dimensions, materials, and arrangement of each component described in this specification are not limited to those explicitly described in the embodiments, and each component can be modified to have any dimensions, materials, and arrangement that can be included in the scope of the present invention. Furthermore, components not explicitly described in this specification can be added to the described embodiments, and some of the components described in each embodiment can be omitted.
