Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an improvement of a fishing reel equipped with a line length measuring device that detects the number of rotations of a spool in a double-bearing type reel and measures and displays the length and line speed of the line delivered from the spool.

[0002]

[Prior art]

 The detection means in the conventional measuring device for the length of the fishing line and the speed of the fishing line, which is used in the conventional Japanese Patent Publication No. 57-15847 and Japanese Utility Model Laid-Open No. 7-39435, rotates together with the spool and has a magnet on one side. The rotating body has a magnet and a magnetic sensor including a reed switch provided on the reel body so as to face the magnet on one side of the rotating body. The rotating body having the magnet is rotated by the rotation of the spool when the fishing line is fed. By magnetically detecting the magnetic attraction action approaching the reed switch of the magnet, this detection signal is transmitted to the electronic control unit to measure and display the fishing line length and line speed.

[0003]

[Problems to be solved by the device]

 However, in such a system, since the rotating body provided with the magnet is inclined and rotated with respect to the bearing portion due to the magnetic attraction when the reed switch detects the magnetism, the rotation resistance increases and the spool rotates. However, there is a problem that the rotation performance is deteriorated and the detection performance cannot be stably maintained for a long period of time due to accelerated wear. In view of these circumstances, it is an object of the present invention to provide a fishing reel which has these defects improved and has a smooth spool rotation performance and a stable rotation number detection function for a long period of time. Is.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention rotatably supports a spool between side plates of a reel body, rotates with the spool, and has a magnetic sensor lead on one side of a rotor having a magnet on one side. A fishing reel in which switches are arranged to face each other and the number of rotations of the spool is detected by a magnetic sensor, and the detected number of rotations is transmitted as a signal to be measured and displayed on an electronic control unit body provided above the reel unit. The reel body is provided with a magnetic body on the other side of the rotating body so as to face the reed switch. The rotating body is provided on a spool shaft having a spool, and In some cases, the shaft is provided separately from the shaft and is supported by the reel unit so that it can be rotated by an interlocking gear provided on the spool shaft.

[0005]

[Embodiment of the invention]

 The embodiment of the present invention will be described with reference to the embodiments of the drawings. A spool shaft 4 having a spool 3 is rotatably supported between side plates 2 and 2'of a reel main body 1 of a dual bearing reel. The spool shaft 4 is connected to a handle 6 through a clutch mechanism 5 provided on the side plate 2 side, and the end of the spool shaft 3 on the side plate 2'side is connected to a rotating body 7 pivotally supported by the side plate 2 '. It is engaged and disengaged.

A magnet 8 is installed on one side of the rotating body 7 on the side plate 2 ′ side, which is an outer side surface, and the magnet 8 faces a lead switch 9 of a magnetic sensor installed on the inner side surface of the side plate 2 ′. On the side of the spool 3 which is the inner surface of the rotating body 7, a magnetic body 10 is attached to the side plate 2 ′ so as to face the reed switch 9.

Therefore, the number of rotations of the magnet 8 of the rotating body 7 due to the rotation of the spool 3 is detected by the magnetic detection function of the reed switch 9, and this is installed on the reel main body 1 as is known. A signal is transmitted to the electronic control unit body 11 so that the fishing line length and the fishing line speed can be measured and displayed.

Since the embodiment of the present invention is configured as described above, when the rotating body 7 is rotated through the spool shaft 4 by the feeding of the fishing line wound on the spool 3, the rotation of the magnet 8 is led. While the switch 9 detects and transmits the signal to the electronic control unit body 11 to measure and display the length of the fishing line and the speed of the fishing line, the magnet 8 of the rotating body 7 and the lead switch 9 act by magnetic attraction. The inclination of the rotating body 7 with respect to the bearing is prevented by balancing the magnetic force applied to the rotating body 7 by the magnetic body 10 at a position facing the reed switch 9 with the rotating body 7 interposed therebetween.

In the embodiment shown in FIG. 3, the rotating body 7 is formed as a gear and is pivotally supported on the side plate 2 ′ by a shaft 7 ′ separately from the spool shaft 4 and is rotated integrally with the spool shaft 3. A magnetic body 10 is provided on a frame 1 ′ of the reel unit 1 while being engaged with the gear 12 to rotate.

In the embodiment shown in FIG. 4, the reed switch 9 and the rotating body 7 of the magnetic sensor in FIG. 3 are not provided on the side plate 2 ′, but the reed switch 9 and the rotating body 7 are integrated into the electronic control unit body 11. It is provided on each of the mounting portions 11 'extending in the direction, and the mounting portions 11' are detachably fixed to the inner portion of the side plate 2'by means such as screws.

[0011]

[Effect of the invention]

 According to the present invention, the inclination of the rotating body due to the magnetic attraction action of the reed switch and the magnet when the number of rotations of the spool is detected is balanced by the magnetic body installed opposite to the reed switch with the rotating body sandwiched between them. As a result, resistance and wear due to local contact in the bearing portion of the rotating body can be prevented, and smooth rotation of the spool and improvement of the detection function can be achieved.
