Description

[Detailed Description of the Invention] This invention relates to a device for measuring the length of fishing line reel on a double-bearing reel.

Utility Model Publication No. 49-27115 is a mechanism for measuring the unwinding length (winding length) of the fishing line around which the spool is wound in this type of double-bearing reel.

This device has a roller pressed against the outer circumferential surface of the fishing line that can be wound around a spool, and a worm attached to the rotating shaft of the roller is meshed with the worm gear of a distance counting counter. The circumference of the part where the fishing line is wound
It is designed to reliably read and display short and short characters.

However, since the above-mentioned idea transmits the rotation of the roller to the gear of the counting counter via a gear mechanism to operate the counting counter, problems are likely to occur in the meshing of the gears in the rotation transmission path. However, it has been difficult to maintain stable functionality over a long period of time.

The present invention was developed to solve the above-mentioned drawbacks of the conventional technology, and uses optical detection means to detect the rotational speed of a roller that rotates while being in elastic contact with the outermost circumference of a fishing line wound around a spool. This solves the drawbacks of the mechanical means described above and makes it possible to maintain stable measurement functions over a long period of time.

The measuring device of the present invention that achieves this purpose has a light emitter and a light receiver installed facing each other on the side plate of a frame which supports a roller freely rotatably, and a roller located between the emitter and the light receiver. The method is characterized in that a through hole is opened through which the light from the projector enters the light receiver, and the output of the optical detection means consisting of the projector and receiver is processed by an electric circuit and the length is measured. .

In the measuring device of the present invention, the detection means for detecting the number of rotations of the roller is composed of a light projector installed opposite to the frame supporting the roller, and a light receiver that receives the light emitted from the projector. ing.

Also, if you want to simultaneously detect the rotational speed of the roller as well as the rotational direction, that is, rotation in the direction of feeding out the fishing line or rotation in the direction of reeling the fishing line, it is possible to do so by arranging multiple sets of emitters and receivers. be.

The detection means is connected to an electric circuit, and the output signal emitted by the detection means is input to a microcomputer or digital circuit and processed, and the actual length (m) is displayed on an LED (light emitting diode display), LCD (liquid crystal display), etc. Depending on the means, it is output and displayed as a number.

In addition, the data input to the electric circuit and processed is not only displayed as the actual measured length, but also controls various operations such as the brake that stops the rotation of the spool, and the ON/OFF control of the motor in the electric reel. used for.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows a measuring device equipped with a mounting means that can be detachably attached to both bearing shaft reels. 4 is a light emitter fixed to the side plate 2' of the device frame 2, 4 is a receiver fixed to the device frame 2 facing the projector 3, and 5 is a through hole drilled through the roller 1; The light projector 3 is located so that the light emitted by the light receiver 4 enters the light receiver 4 .

Reference numeral 6 denotes a mounting means for attaching to the double-bearing reel (shown in the figure), which can be attached and detached by turning a screw.
The base 2'' of the spool 7 is rotatably supported, and is biased by a spring so that the roller 1 is pressed into contact with the bobbin winding surface 8 of the spool 7.

Reference numeral 9 denotes a rubber ring attached to the outer peripheral surface of the roller 1, which accurately captures the rotation of the spool 7 and allows the roller 1 to rotate in conjunction with the rotation.

Furthermore, the three sets of emitters and receivers 4 attached to the side plate 2' of the container frame 2 detect the number of rotations of the roller 1, and at the same time detect whether the rotation direction of the roller 1 is forward or reverse. I'm starting to get it.

With the above configuration, when the spool 7 is driven and rotated by the rotation of the handle or the tension of the fishing line, the roller 1, which is in elastic contact with the outermost circumference of the bobbin, rotates due to contact friction.

The roller 1 is provided with a through hole 5, and each time the roller 1 rotates, the light emitter/receiver 3, 4
The light emitted by the light emitter 3 is received by the light receiver 4, the rotation speed of the roller 1 is detected, and the output signal of the light receiver 4 is input to a microcomputer or digital circuit for processing and actual measurement. The length (m) is output and displayed as a number by a display means such as LED or LCD.

The fishing line payout length measuring device of the present invention detects the rotation of a roller that rotates by being in elastic contact with the outermost periphery of a line wound around a spool that is driven and rotated, using a detection means consisting of a light emitter and a light receiver, and outputs the Since the roller is processed by an electric circuit and the length is measured, the number of rotations of the roller can be detected without contacting the roller.

Therefore, if sand or the like adheres to the winding part of the fishing line wound around the spool, in conventional devices, the sand gets bit into the gear mechanism through the rollers, interfering with the operation of the counting counter, and making it impossible to measure the length. However, with this invention, even if sand or the like adheres to the roller, it does not affect the rotation speed detection for length measurement at all, and stable operation can be achieved over a long period of time. It is something that can be secured.

Moreover, the data that is input to the electric circuit and processed is not only displayed as the actual measured length, but also controls various operations such as the brake that stops the rotation of the spool, the ON/OFF of the motor in the electric reel, etc. It is very convenient because it allows you to
