[Patent Document 1] Japanese Patent Laid-Open No. 2007-195433

This type of previous double-bearing reel is oriented toward the end of the reel shaft and the bearing receiving portion. The first side plate protrudes. Therefore, in order to ensure a space for accommodating a power source, the space is restricted, and the design is also restricted in the design. Furthermore, the space between the first side cover and the first side plate is increased, whereby the length in the spool axis direction of the dual-bearing reel becomes longer.

An object of the present invention is to reduce the length in the spool axis direction of a double-bearing reel.

The double bearing reel according to the present invention is a person who can install a fishing rod and release the fishing line forward. The double bearing reel includes a handle, a reel body, a reel, and a reel shaft. The reel main body has a frame including a first side plate and a second side plate facing the first side plate, and a fishing rod attachment portion provided on the frame and capable of attaching a fishing rod. In this system, the handle is provided on the side of the second side plate. The reel has a cylindrical reel body portion capable of winding a fishing line, a pair of flange portions formed on both sides of the reel body portion with a diameter larger than the reel body portion, and integrally formed on the reel body with the reel body portion. Mounting portion on the inner peripheral side of the barrel portion. The reel shaft is integrally rotatably connected to the mounting portion, and is rotatably supported by the reel body. The first side plate has a cylindrical bearing housing portion extending to the inner peripheral side of the bobbin body portion. The first end portion on the first side plate side of the spool shaft is rotatably supported on the inner peripheral side of the spool body portion by the first bearing received in the bearing receiving portion and supported in the bearing receiving portion.

The first end portion of the double-bearing reel system is supported by a first bearing accommodated in a bearing accommodation portion extending to the inner peripheral side of the reel body portion. Therefore, the first end of the first side plate side of the reel shaft is supported by the first bearing at a position closer to the handle side than the conventional double bearing winder. Thereby, the first side plate can be brought as close as possible to the reel, so that the length in the reel axis direction of the dual-bearing reel can be shortened.

The first side plate may further include a side receiving portion extending from the bearing receiving portion. In this case, since the first side plate near the handle side has a side receiving portion extending from the bearing receiving portion, even if a power supply and other parts are installed in the side receiving portion, the length in the direction of the reel axis of the dual bearing reel can be made Get shorter.

The side accommodating portion may be partially disposed on the inner peripheral side of the flange portion on the first side plate side of the roll. In this case, since a part of the side accommodating portion is disposed on the inner peripheral side of the flange portion of the roll, the side accommodating portion is closer to the handle side. Thereby, even if a side accommodating portion is provided, the length in the reel axis direction of the dual-bearing reel can be further shortened.

The double-bearing reel may further include a calculation unit that displays information about the fishing line. At least a power supply unit that supplies power to the computing unit is housed in the side housing unit. In this case, even if the relatively large power supply section is accommodated in the side accommodating section, the length in the direction of the reel axis of the dual-bearing reel can be shortened.

The calculation unit may include a rotation detection unit, a rotation direction detection unit, and a line length calculation unit. The rotation detecting section detects the rotation of the reel. The rotation direction detection unit detects the rotation direction of the roll based on the detection result of the rotation detection unit. The line length calculation unit calculates the length of the fishing line taken up or released based on the detection results of the rotation detection unit and the rotation direction detection unit. In this case, the water depth of the fishing group can be obtained by calculating the line length.

The calculation unit may include a speed calculation unit that calculates the take-up speed or the take-off speed of the roll based on the detection result of the rotation detection unit. In this case, the speed of the reel can be obtained during winding and unwinding.

The double bearing reel can further include: a counter box, which is disposed at a position of the reel body away from the fishing rod installation portion; and a display unit, which is housed in the counter box and displays the length of the fishing line calculated by the arithmetic unit. In this case, the angler can recognize the water depth of the fishing group, so that it is easy to arrange the fishing group in the position where the fish gathers.

The computing unit can also be housed in a counter box. In this case, since the calculation section may not be arranged on the side accommodating section, even if the calculation section is provided, the length in the reel axis direction of the dual-bearing reel can be shortened.

The reel main body may further include a first side cover covering the outer side of the first side plate, and a second side cover covering the outer side of the second side plate. The second end portion of the spool shaft opposite to the first end portion is rotatably supported by the second side cover by a second bearing mounted on the second side cover. herein In this case, since the first side cover and the second side cover are provided, the internal mechanism of the double bearing winder is not exposed to the outside.

The side storage portion may be covered by a first side cover. In this case, even if electrical parts such as a power supply are stored in the side accommodating portion, failures such as poor insulation are unlikely to occur in the electrical parts.

According to the present invention, the first end of the first side plate side of the spool shaft is supported by the first bearing at a position closer to the handle side than the conventional double-bearing reel. Thereby, the first side plate can be brought as close as possible to the reel, so that the length in the reel axis direction of the dual-bearing reel can be shortened.

The relationship between the number of reels and the line length in the total length of different lengths of a plurality of types of fishing lines is memorized in the storage unit 41 when the following line winding mode is the designated mode. For example, there are stored coil data of No. 4 100m, No. 3 150m, and No. 2 200m formed by so-called PE (polyethylene, polyethylene) wires formed by twisted wires made of ultra-high molecular weight polyethylene. In addition, the coiling data of different types of coilers are also stored in the memory section 41, and the counter box 15 is realized in common with the double bearing coilers of different models.

Next, the configuration of the control system including the arithmetic unit 30 will be described based on FIG. 5.

The calculation unit 30 includes a rotation detection unit 51, a rotation direction detection unit 52, a line length calculation unit 53, and a speed calculation unit 54, and is configured as a function realized by software. The rotation detection unit 51 detects whether the reel 14 is rotated by the pulse output of the reel sensor 36. The rotation direction detecting section 52 is that if the rotation detecting section 51 detects the rotation of the reel 14, then at this time, any of the magnetic detectors 36a and 36b outputs a pulse signal first, and the rotation direction of the reel 14 is detected as the winding direction Or pay off direction. The line length calculation unit 53 detects the number of reels based on the pulse output from the reel sensor 36 detected by the rotation detection unit 51 and the rotation direction detected by the rotation direction detection unit 52. The relationship between the number of reel rotations and the line length is used to calculate the line length of the detected number of reel rotations and display it on the display unit 20 as the depth of the fishing group. The speed calculation unit 54 calculates the rotation speed of the reel 14 based on the number of pulses per unit time of the pulse output detected by the rotation detection unit 51.

In the double-bearing reel 10 configured in this manner, the bearing accommodating portion 24 b is arranged on the inner peripheral side of the reel body portion 14 a of the reel 14. Therefore, the first end on the side of the first side plate 17a of the reel shaft 26 is supported by the first bearing 25a at a position closer to the handle 12 side than the conventional double bearing winder. Thereby, the end portion of the reel shaft 26 and the bearing accommodation portion 24b do not protrude toward the first side plate 17a, so that the first side plate 17a can approach the reel 14 as much as possible, so that the reel shaft direction of the dual-bearing reel 10 The length becomes shorter.

<Feature>

The above embodiment can be expressed as follows.

(A) The double-bearing reel 10 is a double-bearing reel 10 capable of attaching a fishing rod and releasing a fishing line forward. The double-bearing reel 10 includes a handle 12, a reel body 11, a reel 14, and a reel shaft 26. The reel main body 11 includes a frame 17 including a first side plate 17a and a second side plate 17b facing the first side plate 17a, and a fishing rod attachment portion 17d provided on the frame 17 and capable of attaching a fishing rod.

The reel 14 includes a cylindrical reel body portion 14a capable of winding a fishing line, and a first flange portion 14b and a second flange portion formed on both sides of the reel body portion 14a with a diameter larger than that of the reel body portion 14a. 14c and a mounting portion 14d integrally formed with the spool body portion 14a on the inner peripheral side of the spool body portion 14a. The spool shaft 26 is rotatably coupled to the mounting portion 14d, and is rotatably supported by the reel body 11. The first side plate 17a has a cylindrical bearing housing portion 24b extending to the inner peripheral side of the spool body portion 14a. The first end portion on the first side plate 17a side of the spool shaft 26 is rotatably supported on the inner peripheral side of the spool body portion 14a by the first bearing 25a housed in the bearing housing portion 24b in the bearing housing portion 24b.

In this double-bearing reel 10, the first end portion of the spool shaft 26 is supported by a first bearing 25a housed in a bearing housing portion 24b extending to the inner peripheral side of the spool body portion 14a. Therefore, the first end on the side of the first side plate 17a of the reel shaft 26 is supported by the first bearing 25a at a position closer to the handle 12 side than the conventional double bearing winder. Thereby, the end portion of the reel shaft 26 and the bearing accommodation portion 24b do not protrude toward the first side plate 17a, so that the first side plate 17a can be as close to the reel 14 as possible, so that the reel shaft of the dual-bearing reel 10 can be made The length in the direction becomes shorter.

(B) The first side plate 17a may further include a power supply accommodating portion (an example of a side accommodating portion) 24c extending from the bearing accommodating portion 24b. In this case, the end of the reel shaft 26 and the bearing receiving portion 24b do not protrude toward the first side plate 17a, and the first side plate 17a close to the handle 12 side has a power receiving portion 24c extending from the bearing receiving portion 24b. The components such as the power supply can be freely stored in the power supply accommodating portion 24c, and even if the components such as the power supply are installed, not only the length in the direction of the reel axis of the double-bearing reel 10 can be shortened, but also the appearance design can be changed. More compact, so that the degree of freedom in design can be increased.

(C) The power supply accommodating portion 24c may be partially disposed on the inner peripheral side of the first flange portion 14b on the first side plate 17a side of the roll 14. In this case, since a part of the power supply accommodating portion 24c is disposed on the inner peripheral side of the first flange portion 14b of the reel 14, the power supply accommodating portion 24c is closer to the handle 12 side. Thereby, even if the power supply accommodating portion 24c is provided, the length in the reel axis direction of the double-bearing reel 10 can be further shortened.

(D) The double bearing reel 10 may further include a calculation unit 30 that displays fishing line information. At least a power supply unit 31 that supplies power to the computing unit 30 is housed in the power supply housing unit 24c. In this case, even if the relatively large-volume power supply section 31 is housed in the power supply housing section 24c, the length in the roll axis direction of the dual-bearing reel 10 can be shortened.

(E) The calculation unit 30 may include a rotation detection unit 51, a rotation direction detection unit 52, and a line length calculation unit 53. The rotation detection unit 51 detects the rotation of the reel 14.
