2. Description of the Related Art Humans and natural animals such as birds and beasts (hereinafter referred to as birds and beasts) must coexist with each other, but for human beings who live in social life, they sometimes become hostile to birds and beasts. May not be available. For example, there are cases where birds and beasts eat agricultural crops cultivated in the fields, and wild birds flying in a passage near the airfield obstruct the flight.

A quick solution for suppressing such damage from birds and beasts is to kill them with guns and other weapons. However, this is not feasible in densely populated urban areas and is ethically However, since it is not a desirable solution, we have tried to coexist as much as possible by preventing intrusion into the premises or threateningly letting them go.

Conventionally, various measures have been taken to prevent damage from birds and animals. For example, it is a means for preventing a bird and beast from entering by laying a protective fence or a protective net on a site such as a field. In this case, not only was the initial investment of the equipment costly, but also the cunning birds and beasts were inevitably damaged, and maintenance and maintenance were difficult. In addition, there is a means of generating intimidating sounds such as sirens and air cannons. However, in this case, a large volume must be generated inevitably in order to exert an effect over a wide area, and the noise in a nearby area has been an adverse effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in more detail with reference to the drawings.

[First Embodiment] A first embodiment of the present invention will be described with reference to FIGS. In the figure, what is indicated by reference numeral 1 is a laser-irradiated substrate.
Are formed by arranging a plurality of laser light emitting elements 11, 11,.... In this embodiment, the laser irradiation substrate 1 is formed in a flat plate shape, and a 5 V, 40 mA, 0.2 W laser diode (GaAs-based red visible light semiconductor laser) is adopted as the specification of the laser light emitting elements 11 to be arranged. The laser light L emitted from the laser light emitting element 11 is approximately 300
Demonstrate the ability to threaten birds and beasts m away.

The reference numeral 2 designates a substrate driving mechanism. The substrate driving mechanism 2 is configured to be able to reciprocate and / or oscillate the laser irradiation substrate 1 in this embodiment. In the embodiment, an elevation drive shaft 21 that pivotally supports the laser irradiation base 1 so as to swing in the elevation direction, and a left and right drive shaft 22 that pivotally supports the laser irradiation base 1 so as to swing in the left and right direction.
Thus, the surface angle of the laser irradiation base 1 can be adjusted.

In manufacturing the laser bird / beast threatening device according to the present embodiment, first, each laser light emitting element 11 is placed on the same plane of the laser irradiation base 1 formed in a flat shape.
Are arranged at equal intervals in the vertical and horizontal directions so as to form a bundle in which the emission directions of the emitted laser lights L are substantially parallel. By forming and ejecting a bundle in this way, it is easier to set an aim when irradiating a distant target bird or animal.

Further, the laser irradiation base 1 can be swung in the elevating direction by operating the elevating drive shaft 21 of the base driving mechanism 2, so that it can handle both birds flying above and beasts on the ground. By operating the left and right drive shaft 22, the swing can also be performed in the left and right direction, so that the target bird and animal can be reliably irradiated over a wide range. By attaching a drive motor to each of the elevation drive shaft 21 and the left and right drive shaft 22, the surface angle of the laser irradiation base 1 can be adjusted electrically, which is particularly convenient for remote control. Then, the laser light L directly gives a very strong stimulus to the cornea of the bird's / eye's eyes to give fear,
Can be intimidating.

"Second Embodiment" A second embodiment of the present invention will be described with reference to FIGS. In the present embodiment, a laser irradiation substrate 1 manufactured in a cylindrical shape is adopted, and the laser light emitting elements 11 are radially arranged on the column surface of the laser irradiation substrate 1 and can be emitted in a 360-degree direction. Furthermore, the laser irradiation base 1 can be continuously rotated by pivotally supporting the substantially axis of the laser irradiation base 1 with the rotation shaft 23.

Further, similarly to the first embodiment, by attaching a drive motor to the rotating shaft 23, the rotating operation of the laser irradiation base 1 can be controlled electrically, which is also convenient for remote operation. .

In each of the laser and beast threatening apparatuses of the first and second embodiments described above, a sensor is installed in a target area such as a field to detect the presence of a bird and beast, and the apparatus is accordingly operated. It can be manufactured to turn on / off the power supply. If necessary, by linking the sensor and the angle adjusting mechanism, the target bird and beast can be tracked and aimed, and the laser beam L can be emitted.

The present invention is generally configured as described above.
The present invention is by no means limited to the illustrated embodiment, and various modifications are possible within the scope of the claims. For example, the shape of the laser irradiation substrate 1 may be flat or cylindrical. The present invention is not limited to this. For example, another curved body or prismatic body may be employed, and a wheel, a caterpillar, or the like may be provided on a leg of the apparatus main body so as to be movable.

[0020]

As described in the above embodiments, the laser-type bird-and-beast threatening device of the present invention is manufactured by taking advantage of the characteristics of the laser beam, such as the excellent directivity and the large reach distance, of the bird's-eye. A very strong stimulus can be directly applied to the cornea to intimidate. Also,
It is very preferable from the viewpoint of animal welfare, since it is silent, has no adverse effects on noise to nearby areas, and does not kill birds and beasts with weapons such as guns.

Further, it can be manufactured at low cost and consumes little power. By installing this laser-type bird and beast threatening device in fields and fish farms, it is effective not only for birds but also for monkeys that come to devour, and also for dangerous birds that fly above the vicinity by installing on airfields. This makes it possible to prevent birds from being sucked into the engine of the airplane when the airplane is taking off and landing, thereby preventing serious airplane accidents from occurring.
