Further, reference numeral 15 denotes a reflection paper pasted around the optical sensor 8.

FIG. 2 shows the internal configuration of the automatic fishing device. A hoisting motor 17 is provided beside the swinging motor 16. The front end side of the rotating shaft 18 of the swing motor 16 is supported by a support frame 20, and a rotor 21 is connected to the rotating shaft 18 on the inner side. As shown in FIG. 4, the rotor 21 is configured by combining a large-diameter rotor 21 </ b> A having a magnet 22 protruding from the outer periphery and a small-diameter rotor 21 </ b> B provided on this side surface. An arc-shaped groove 23 is provided on the side surface of the large-diameter rotor 21A, and a pin 24 protrudes from the side surface of the small-diameter rotor 21B opposite to the groove 23, as shown in FIGS. Is inserted into the arc-shaped groove 23.

A large-diameter rotor 21A is inserted into the rotary shaft 18 in a loose fit, and the small-diameter rotor 21B is fixed. Accordingly, the rotation of the rotary shaft 18 causes the small-diameter rotor 21B to rotate integrally, and the rotation of the pin 24 projecting from the rotation shaft 18 causes the pin 24 to move toward the front end in the rotation direction within the arc-shaped groove 23 as shown in FIG. The large-diameter rotor 21A with which the magnet 22 protrudes is abutted to rotate.

As shown in FIG. 3, a swing member 26 is rotatably supported by a support shaft 27 on the inner side of the support frame 20 in front of the rotor 21 and in proximity to the rotor 21. The swinging member 26 has a curved portion 29 formed on the side surface facing the rotor 21, and a magnet 28 is embedded therein. The magnets 28 and the magnets 22 protruding from the rotor 21 are attached so that the opposite sides are, for example, the same polarity of N poles as shown in FIG. The base of the fishing rod 2 is inserted into the front surface of the swing member 26.

Further, as shown in FIG. 2, the hoisting motor 17 provided adjacent to the swinging motor 16 is movably supported by the mounting base 30, and is always pulled forward by the coil spring 31, and the fishing line set lever 12 is moved. It comes to pull back. A small diameter gear 33 </ b> A is attached to the rotary shaft 32 of the hoisting motor 17, and a large diameter gear 33 </ b> B meshing with the small gear 33 </ b> A is attached to the rotary shaft 34 of the fishing line reel 10.

Further, a hoisting stop mechanism 36 is provided between the swinging member 26 to which the fishing rod 2 is attached and the fishing line reel 10. As shown in FIG. 7, the winding stop mechanism 36 has a coil 38 attached to the contact point of the limit switch 37, and a stopper ball 39 opened along the center line is provided in front of the coil 38. When the yarn ball 4 serving as a yarn stopper is hit, the stopper ball 39 is pressed against the coil 38, the limit switch 37 is turned on, and the winding motor 17 is stopped.

As shown in FIG. 2, the optical sensor 8 and the swinging motor 16 are connected to a timer circuit 40, and after the swinging motor 16 has been operated for a predetermined time, it is stopped intermittently, and this is stopped. The operation time is set alternately so that the optical sensor 8 operates only for the time. That is, as shown in FIG. 9, the timer circuit 40 is composed of a timer A for setting the time for the optical sensor 8 to operate and a timer B for setting the time for the swing motor 16 to operate. The motor 16 is intermittently operated alternately.

The optical sensor 8 and the hoisting motor 17 are connected to the hoisting control circuit 41. When the optical sensor 8 does not receive the reflected light from the reflecting plate 3, the hoisting motor 17 is activated. Yes. In the figure, reference numeral 42 denotes a battery serving as a power source.

Next, the operation of the automatic fishing device having the above configuration will be described. First, the timer A of the timer circuit 40 is set to a time for the optical sensor 8 to operate, and the timer B is set in advance to the time for the swing motor 16 to operate. Next, as shown in FIG. 8, the angle of the automatic fishing device and the angle of the reflector 3 are adjusted so that sunlight strikes the reflector 3 and the reflected light strikes the optical sensor 8.

Thereafter, when the fastener 11 of the fishing line reel 10 is removed and the fishing line set lever 12 is moved forward, the meshing of the small diameter gear 33A and the large diameter gear 33B is released as shown in FIG. 10 is in a free state. In this state, the fishing line 4 is fed out from the tip of the fishing rod 2 from the fishing line reel 10 and lowered to the position of the fish layer in the water. After the fixture 11 is attached to the fishing line reel 10, the fishing line set lever 12 is returned.

Next, when the power switch 13 is turned on, the timer B of the timer circuit 40 is operated, and the swing motor 16 rotates for a predetermined time. When the oscillating motor 16 rotates, the small-diameter rotor 21B fixed to the rotating shaft rotates integrally. As a result of the rotation of the pin 24 projecting therefrom, the pin 24 is inserted into the arc-shaped groove 23 as shown in FIG. The large-diameter rotor 21A projecting from the magnet 22 is also rotated in contact with the front end side in the rotation direction.

The rotation of the rotor 21 causes the magnet 22 projecting therefrom to rotate integrally, and when approaching the magnet 28 attached to the swing member 26 as shown in FIG. 3, the N poles have the same polarity. Therefore, the repulsive force works, the swinging member 26 attached with the magnet 28 rotates forward, and the fishing rod 2 attached to the upper part rises. When the rotor 21 further rotates and the magnet 22 moves away, the repulsive force disappears, the swinging member 26 returns due to its own weight, and the fishing rod 2 descends. In this manner, the fishing rod 2 can swing up and down by the rotation of the rotor 21 to automatically perform scorpion.

When this saturation is repeated a plurality of times, the timer B expires and the rotation of the swinging motor 16 stops, and this time the timer A activates the optical sensor 8 for a predetermined time. At this time, if the fish is not hooked on the fishhook 5, the tip of the fishing rod 2 is positioned almost horizontally as in the initial state, so that the light sensor 8 receives the reflected light from the reflector 3 attached here. This is a state and a certain time elapses as it is.

Thereafter, the timer B is activated again and the swinging motor 16 is rotated for a predetermined time, and the fishing rod 2 repeats up and down swinging and intermittently repeats scorpion. When the swinging motor 16 stops, as shown in FIG. 6, when the magnet 22 of the rotor 21 and the magnet 28 of the swinging motor 16 are opposed to each other, the fishing rod 2 is stopped in an upward state while being repelled. As a result, fish information to the optical sensor 8 may not be transmitted. For this reason, the arc-shaped groove 23 is formed on the side surface of the large-diameter rotor 21A, and the large-diameter rotor 21A is guided by the arc-shaped groove 23 while maintaining the state of being connected to the pin 24 of the small-diameter rotor 21B. Is rotated downward by its own weight, and stops at a position where the magnet 22 and the magnet 28 are displaced.

When the swinging motor 16 rotates intermittently and the fishing rod 2 swings up and down while the fish is hooked on the fishhook 5 and pulls the fishing line 4, the phantom line in FIG. The fishing rod 2 bends and the angle of the reflector 3 attached to the tip changes. When the angle of the reflecting plate 3 changes, the reflected light does not reach the optical sensor 8. If the reflected light does not reach the optical sensor 8 in a state where the swing motor 16 is stopped and the optical sensor 8 is activated, the hoisting control circuit 41 is activated and the hoisting motor 17 is switched on. This rotates and the fishing line reel 10 begins to rotate.

As the fishing line reel 10 rotates, the fishing line 4 is taken up through the hoisting stop mechanism 36 and the fish is pulled up. The fishing line 4 is provided with a thread ball 7 serving as a stopper for stopping the thread on the upper portion of the fish hook 5, and when this reaches the hoisting stop mechanism 36, the thread ball 4 is attached to the stopper ball 39 as shown in FIG. Hook and move it backwards. As a result, the stopper ball 39 is pressed against the coil 38, the limit switch 37 is turned on, the hoisting motor 17 is stopped, and the fish can be automatically lifted and taken in. This series of operations is as shown in FIG.

In addition, when sunlight is located in front of the reflector 3, or when it is cloudy and sunlight is not sufficient, the auxiliary light source switch 14 is turned on to irradiate the reflector 3 with light from the auxiliary light source 9 for use. it can. The reflector 3 may be attached to the upper part or the lower part of the tip of the fishing rod 2, and the size thereof can be arbitrarily selected. In the above description, the fishing line 4 is wound up when the fishing rod 2 is bent and the reflected light from the reflecting plate 3 is not received by the optical sensor 8, but the fishing rod 2 is reversed. A structure may be employed in which the fishing line 4 is wound up when the light sensor 8 receives the reflected light from the reflecting plate 3 by bending.
