The present applicant has previously disclosed a line length measuring device for a fishing double-axis reel (hereinafter, referred to as a “double-axis reel”) that measures the feed amount and the winding amount of the fishing line using an ultrasonic sensor (for example, And Patent Documents 1 and 2 below).
These yarn length measuring devices include a rotation number detecting means for detecting a rotation number of a spool rotatably supported between side plates of a reel body, and an ultrasonic wave emitted from an ultrasonic sensor for transmission wound around the spool. A time-measuring means for measuring the time required for the reflected fishing line to be reflected by the winding surface of the fishing line and to be received by the receiving ultrasonic sensor, and to measure the thread diameter based on the time-measured value; Calculating means for calculating the yarn length based on the yarn winding diameter obtained by the diameter measuring means and the detection value obtained by the rotation speed detecting means; and a display for displaying the yarn length calculated by the calculating means. As shown in FIGS. 3 and 4, the dual-axis reel 1 disclosed in Patent Document 1 has a spool of a control box (electronic control mechanism housing) 9 mounted between the side plates 5 and 7 on the upper part of the reel body 3. An ultrasonic sensor 13 for transmission is provided on the facing surface 11. The ultrasonic sensor 15 for reception, is obtained by mounting the V-shape to face the winding face 19 of the fishing line 37 wound spool 17 wound.

Further, as shown in FIGS. 5 and 6, the dual-axis reel 21 disclosed in Patent Document 2 includes a sensor support 23 on which the ultrasonic sensors 13 and 15 are mounted, and a lower side of a thumb rest 27 on the rear side of the reel body 25. The ultrasonic sensors 13 and 15 are mounted on the spool facing surface 29 of the sensor support 23 in a V-shape facing the winding surface 19 of the fishing line 37, and the outside of the sensor support 23 is protected by a protective cover 31. It is characterized by being covered with.
[0004]
As described above, in each of the conventional examples, when the ultrasonic wave is emitted from the ultrasonic sensor 13 to the winding surface 19 of the fishing line 37, the time until the reflected wave is received by the ultrasonic sensor 15 is reduced. First, the time is measured by the time measuring means of the thread diameter measuring means in the control box 9.
Next, the time measured by the time measuring means is converted into an electric signal proportional to the thread diameter, and the fishing line is detected based on the thread diameter signal and the rotational speed of the spool 17 detected by the rotational speed detecting means comprising the magnet 33 and the reed switch 35. The feeding amount of 37 is calculated by the calculating means, and the numerical value is displayed on a digital display (hereinafter, referred to as “display”) 41 provided on the operation panel 39 on the control box 9.
[0005]
Thus, by attaching these line length measuring devices, it became possible to measure the feeding amount and the winding amount of the fishing line 37 with high accuracy.

The fishing line 61 is wound uniformly around the spool 43, and the fishing line 61 wound around the spool 43 is fed uniformly along with the feeding of the fishing line 61.
[0014]
As shown in FIGS. 1 and 2, between the side plates 49 and 51 of the reel body 47, a flat control box 77 is attached to the upper front of the spool 43, and a microcomputer of the yarn length measuring device is provided therein. Is incorporated.
In FIG. 1, reference numeral 79 denotes a rotational speed detecting means for detecting the rotational speed and the direction of the spool 43. The rotational speed detecting means 79 is provided with a pair of reed switches 81 mounted in the side plate 49 and opposed to the pair. And a plurality of magnets 83 fixed to the inner peripheral edge of the spool 43. Then, the microcomputer takes in the forward / reverse rotation determination signal of the spool 43 obtained by turning the reed switch 81 on or off by the magnet 83 at any point, and counts up or down the built-in up / down counter. In addition to setting the state, the rotation pulse of the spool 43 obtained by turning on / off the reed switch 81 is input to an up / down counter to measure the number of rotations of the spool 43, which is used for a calculation of a yarn length measurement described later. It has become.
[0015]
Then, the calculation result is displayed as an amount of feeding and winding of the fishing line 61 on a display mounted on an operation panel (not shown) above the control box 77.
