## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to fishing reels, fishing information display devices, and fishing information display systems. More particularly, the invention relates to a fishing reel storing first information on the reel internally, as well as a fishing information display device and a fishing information display system for displaying the first information and second information.
2. Background Information
A fishing reel is generally furnished with a reel body; a spool mounted to the reel body; a handle for rotating the spool; a counter case mounted above the reel body; and a display device provided on the upper surface of the counter case and including a display unit for displaying water depth. The display unit is, for example, a liquid crystal display and is capable of displaying first information concerning the reel, such as fish zone and current water depth of terminal tackle.
A fishing boat is generally equipped with an information collecting device, such as a fish finder and a global positioning system (GPS), that is adapted for collecting second information concerning fishing. The information collecting device of this kind is provided with a display unit adapted for displaying the second information, as disclosed in Japanese Laid-Open Patent Application Publication No. 2002-142623. The information collecting device of this kind is often disposed at a location distant from the angler. For this reason, the information displayed on the display unit, which relates to fishing, is conveyed verbally from a boatman to the angler.
The foregoing fishing reel equipped with the conventional display device displays first information on a display unit in the counter case. In recent years, however, the amount of the first information concerning the reel has increased so that it has become difficult to display all the information on the display unit. In view of this problem, it is conceivable that the size of the display unit itself is increased in the arrangement, but this can cause an increase in the size of the reel. If the size of the reel is increased, “palming” or holding the reel becomes difficult.
Meanwhile, the foregoing conventional information collecting device is provided with the display unit, so that the second information can be obtained. However, since the information collecting device is disposed at a location distant from the angler, the angler is offered the second information, for example, verbally from the boatman, which makes it difficult to obtain the second information on a real-time basis.
In view of the above, there exists a need for fishing reels which overcome the above mentioned problems in the prior art. This invention addresses this need in the prior art as well as other needs, which will become apparent to those skilled in the art from this disclosure.

The information coordinating-and-controlling unit 71 is capable of selectively controlling any of the components operatively connected thereto in accordance with the control program. It will be apparent to those skilled in the art from this disclosure that the precise structure and algorithms for the information coordinating-and-controlling unit 71 can be any combination of hardware and software that will carry out the functions of the present invention. In other words, “means plus function” clauses as utilized in the specification and claims should include any structure or hardware and/or algorithm or software that can be utilized to carry out the function of the “means plus function” clause.
The information communication unit 52 can communicate wirelessly with the information communication unit 51, which is provided for the fishing information display device 60 as shown in FIG. 3. The information communication unit 52 can also communicate with the fish finder 53 and the GPS 54 through a cable.
The operation key unit 72 is adapted for inputting information that a boatman wishes to convey, for example, information for instructing lowering of the terminal tackle. The input information is stored in the memory unit 73, and is transmitted to the fishing information display device 60 on which the input information is displayed. Herein, since contents that have been conveyed by the boatman through a microphone are displayed on the fishing information display device 60, transmission of the information is made easier and more reliable.
Next, major control processes for the reel that are carried out by the reel control unit 30 are described with reference to control flowcharts of FIGS. 4–6.
When an external power supply is connected to the electric reel, an initial configuration is set in step S1 shown in FIG. 4. More specifically, various flags are reset, and the display mode is reset to “Fishing” mode.
In step S2, a display process is executed for the first display unit 5 and the second display unit 63. More specifically, if the display mode of the second display unit 63 is in the Fishing mode, the water depth and speed that have been computed are displayed, as shown in FIG. 7. If the second display unit 63 is in “Communication” mode, an initial display for the Communication mode shown in FIG. 8 is displayed. In the initial display for the Communication mode, two menu items “Fish Finder Information” and “GPS Information” are displayed as the communication menu. These two types of information concerning fishing can be selected by operating the operation key unit 6.
Herein, the item “Fish Finder Information” is for processing the second information concerning fishing that is obtained from the fish finder 53. The item “GPS information” is for displaying positional information, which is the second information concerning fishing that is obtained from the GPS 54. Thus, as shown in FIG. 9, information concerning fishing regarding a fishing location, such as information concerning fish schools or water temperature, can be obtained through graphics and/or numerical values.
In step S3, it is determined whether there has been a key input interruption through operation of the various keys on the operation key unit 6. If there has been a key input in step S3, the process flow proceeds to step S6 to perform the process required by the key operation.
In step S4, it is determined whether the spool 10 has rotated. The determination is made based on the output from the spool sensor 41. If it is determined that the spool 10 is rotating, the process flow proceeds from step S4 to step S7. In step S7, it is determined whether the Communication mode is on, and if the Communication mode is on, the process flow proceeds to step S8 to switch the display mode from the Communication mode to the Fishing mode. If the Communication mode is off and if the process of step S8 finishes, the process flow proceeds to step S9 processes corresponding to the operation mode (Fishing mode) are performed.
In step S5, it is determined whether there have been any other instructions. If other instructions are made, the process flow proceeds to step S10 to execute other processes corresponding to the instructions.
In the key input process of step S6, it is determined whether the Mode key MD has been operated in step S11 shown in FIG. 5. In step S12, it is determined whether the Change-Speed key SK or the Motor key has been operated. In step S13, it is determined whether other keys have been operated.
If it is determined that the Mode key MD has been operated, the process flow proceeds from step S11 to step S15 to determine whether the display mode is in the Fishing mode. If the Fishing mode is on, the process flow proceeds to step S16 to switch the display mode to the Communication mode. If the Communication mode is on, the process flow proceeds to step S17 to switch the display mode to the Fishing mode. When the display mode is switched to the Communication mode, the information communication unit 50 is controlled so that communication with the fishing information display device 60 is possible, and an initial display shown in FIG. 8 is presented in the display processing at step S2 shown in FIG. 4.
If the Change-Speed key SK or the Motor key is operated, the process flow proceeds from step S12 to step S18. In step S18, it is determined whether the display mode is in the fishing mode. If the display mode is determined to be in the fishing mode, the process flow proceeds to step S19 to execute a motor control process according to the operated key, which is either the Change-Speed key SK or the Motor key. For example, if the Motor key is press-operated, the motor 12 is turned on or off. In the case of the Change-Speed key SK, if the upper switch SK1 is press-operated, an accelerating process is executed, while if the lower switch SK2 is press-operated, a decelerating process is executed.
In the case of the Communication mode, the process flow proceeds to step S20 to execute a menu control process, in which menus are controlled by cursor movement.
In the menu control process of step S20, a cursor on the first display unit 5 is moved by operating the upper switch SK1 or the lower switch SK2 shown in FIG. 2, and menu selection is made by pressing the center switch, which is located between the upper switch SK1 and the lower switch SK2. For example, in the communication menu shown in FIG. 8, when the upper switch SK1 or the lower switch SK2 is pressed, a cursor moves vertically between menu items. The menu item is selected by press-operation of the center switch, whereafter information is received from the information communication unit 50, and the process flow moves to the next process. Then, when the cursor is moved vertically by operating the upper switch SK1 or the lower switch SK2 and some selection operations are performed, the second information as shown in FIG. 9 concerning fishing at the fishing location obtained from the fish finder 53 is displayed.
In each of the processes of respective operation modes in step S9, it is determined in step S41 shown in FIG. 6 whether rotational direction of the spool 10 is in a line-Line Feeding direction or not. The judgment is made based on which of the lead switches of the spool sensor 41 emitted a pulse earlier. If it is determined that the rotational direction of the spool 10 is in a line-Line Feeding direction, the process flow proceeds from step S41 to step S42.
In step S42, data stored in the memory unit 45 are read out to compute the line length that has been reeled out, based on a count value indicated by the spool counter 42. The spool counter 42 decreases with every pulse from the spool sensor 41 in a predetermined timing. A water depth LX is then computed from the line length. The water depth LX thus obtained is displayed in the display process of step S2. Examples of the screens shown on the first display unit 5 and on the second display unit 6 are depicted in FIGS. 2 and 7, respectively. In the processes for the respective operation modes in the fishing mode, the first display unit 5 and the second display unit 63 display such information as water depth of the terminal tackle, fish zone, speed of the spool 10, and the like.
In step S43, it is determined whether the obtained water depth LX matches the fish zone, that is, whether the terminal tackle has reached the depth zone or not. If the terminal tackle has not reached the depth zone yet, the process flow proceeds to step S44.
In step S44, it is determined whether any other fishing mode is on. If no other fishing mode is on, the processes for the respective operation modes are terminated and the process flow returns to the main routine.
If the water depth matches the fish zone, the process flow proceeds from step S43 to step S45, and the buzzer 43 is sounded to report that the terminal tackle has reached the depth zone. If any other fishing mode is on, the process flow proceeds from step S44 to step S46, in order to execute other mode that is turned on.
If it is determined that the rotation of the spool 10 is in the line winding direction, the process flow proceeds from step S41 to step S49. In step S49, data stored in the memory unit 45 are read out and the line length that has been reeled out is computed according to the count value indicated by the spool counter 42, which increases with every pulse from the spool sensor 41 in a predetermined timing. The water depth LX is further computed from the line length. The water depth LX thus obtained is also displayed in the display process at step S2.
In step S50, it is determined whether the water depth matches a boat side stoppage position. If the line has not yet been reeled in up to the boat side stop position, the process flow returns to the main routine.
If the boat side stoppage position is reached, the process flow proceeds from step S50 to step S51. In step S51, the buzzer 43 is sounded to alert that the terminal tackle is at the boat side. In step S44, the motor 12 is turned off. In this manner, in catching a fish, the fish can be positioned such that it is easily taken in. The boat side stoppage position is set, for example, when the water depth is 6 m or less and the spool 10 has been stopped for a predetermined period of time or longer.
In this electric reel, the fishing information display device 60 is enabled to display the first information obtained from the reel and the second information obtained from the fish finder 53 and the GPS 54 through the information coordinating device 70. In addition, the fishing information display device 60 can be controlled with the operation key unit 6 of the electric reel, and the electric reel can be controlled with the operation key unit 62 of the fishing information display device 60.
Herein, the electric reel is adapted for outputting the first information concerning the reel to outside. Therefore, by displaying the first information on the fishing information display device 60 that is provided separately from the electric reel, a large amount of information can be displayed while the size of the reel is kept small. In addition, since the second information concerning fishing is displayed on the fishing information display device 60, the second information can be obtained quickly.
OTHER EMBODIMENTS
(a) In the foregoing embodiment, the fish finder 53 and the GPS 54 are shown as examples of information collecting means on a fishing boat. However, when the fishing boat has a function of collecting information via the Internet, it is possible to employ a configuration such that the information obtained via the Internet can be displayed. Similarly, when the fishing boat is enabled to collect topographical information of the sea bottom or the like, it is possible to employ a configuration such that the obtained topographical information can be displayed. The information may be digitized, high-density information.
(b) In the foregoing embodiment, an electric reel was taken as an example of the fishing reel, but the invention is not limited thereto and may be applied to a hand-winding counter reel or the like.
(c) It is possible to further provide identifying information storage means for holding a unique ID code (identifying information) that specifies a reel, and configure the information communication unit 50 to transmit the ID code to the fishing information display device 60. Alternatively, it is possible to provide identifying information for the fishing information display device 70, and configure the information communication unit 51 to transmit the ID code to the fishing reel. In this case, the information concerning fishing can be made up of information that is related to the ID code sent by the information transmitting means. This way, the information concerning fishing that suits for a variety of reels can be received through bi-directional communications by sending the unique ID code specifying the reel.
(d) The first display unit 5 and the second display unit 63 may be switchable between a detailed standard display screen that displays all of the first and second information in a detailed manner and a simple display screen that shows the items of the first and second information in a simplified manner. For instance, in the case of the first display unit 5, the simplified screen shown in FIG. 11 only shows the water depth display area 5a, the three-digit bottom water depth display area 5b, and the gear speed display area 5c. In other words, the simplified screen shows fewer items than those shown in the standard display depicted in FIG. 2. Accordingly, the simplified screen shows the water depth display area 5a and the three-digit bottom water depth display area 5b in larger fonts than those in the standard display.
(e) Ways of connecting between the electric reel and the fishing information display device 60, and ways of connecting between the fishing information display device 60 and the information coordinating device 70 are not limited to the foregoing embodiment, but may be any combinations of cable communications and wireless communications. Also, the method of wireless communication is not limited to such wireless communication technology as Bluetooth wireless technology or Wi-Fi radio technology, but infrared communications and other communication protocols may be adopted. Further, the information coordinating device 70 may be eliminated and the fish finder 53 and the GPS 54 may be directly connected to the fishing information display device 60. Also, although a plurality of terminals, namely the fish finder 53 and the GPS 54, were described as being connected as information collecting terminals in the afore-described embodiment, this is not meant to be restrictive and only one of these terminals may be connected.
(f) In the embodiment, the fishing information display device 60 is supplied with power from an external power supply, but power may be supplied by an internal battery. In addition, although the electric reel and the fishing information display device 60 are described as being connected by the reel code 19 in the above-described embodiment, the electric reel and the external power supply may also be directly connected. Further, the shape of the connector for the code is not limited to the socket type or the alligator type.
(g) In the foregoing embodiment, the fishing information display device 60 is provided externally of, and spaced from the electric reel, but it may be configured so that the fishing information display device can be detachably mounted on a front or an upper portion of the case member 4 of the electric reel. In addition, the fishing information display device 60 may be provided with an openable and closable cover member that covers the second display unit 63, for shielding from external light. In this case, visibility of the second display unit 63 is improved and the surface of the second display unit 63 is protected when the cover member is closed.
(h) In the foregoing embodiment, the first information and the second information are displayed on the second display unit 63 of the fishing information display device 60, but they may be displayed on the first display unit 5 of the electric reel.
(i) In the foregoing embodiment, the fishing information display device 60 can be controlled with the operation key unit 6 of the electric reel and the electric reel can be controlled with the operation key unit 62 of the fishing information display device 60. However, the control need not be bi-directional; it is possible to employ a configuration in which control of only one of the directions is possible.
(j) It is also possible, as shown in FIG. 10, to employ a configuration in a first reel control unit 31, which is provided on a side of the reel and is capable of controlling one part of the reel, and a second reel control unit 66, which is provided on a side of the fishing information display device 60 and is capable of controlling the other part of the reel. Connected to the first reel control unit 31 is a motor 12 via a PWM driving circuit 44, while various keys of the operational key unit 62, the second display unit 63, and the memory unit for storing various data are connected to the second reel control unit 66.
In this embodiment, the fisherman operates the operational key unit 62 of the fishing information display device 60 based on various data such as a plurality of inducing data stored in the memory unit 67. In this manner, it is possible to conduct controls such as the fish zone stoppage function, the inducing function, and the automatic dangling function, which are reel-controlling functions, via the information communication unit 5 1, the information communication unit 50, and the first reel control unit 31. In this case, when the fishing information display device 60 is not connected to the reel, it is possible to conduct only minimum-necessary functions such as rotational control of the motor 12. On the other hand, when the fishing information display device 60 is connected to the reel, it is possible to conduct additional controls using the second reel control unit 66 of the fishing information display device 60. Therefore, it is possible to simplify the structure of the reel control and improve the operability of various operations. It is also possible to expand the functions of only the information display device side incrementally, without having to expand the reel.
Although the memory unit 45 is connected to the reel control unit 30 on the reel side in the above-describe embodiment, the memory unit 67 can alternatively be connected to the second reel unit 66 on the fishing information display unit 60. In this manner, it is possible to simplify the structure of the reel, and store many data in the memory unit 67 of the fishing information display device 67.
According to one aspect of the present invention, an output means adapted for outputting the first information concerning the reel is provided externally. Therefore, a large amount of information can be displayed while the size of the reel is kept small. In addition, since the second information concerning fishing is displayed on the second display unit, the second information can be obtained quickly.
According to another aspect of the present invention, the fishing reel has a first external control means adapted for controlling a fishing information display device used for the reel. Therefore, operability of the reel is improved in various operations.
