  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same members are designated by the same reference numerals, and the description of the members once described is omitted as appropriate.

  FIG. 1 (a) is a diagram for explaining the structure and operation of the animal repellant device according to one embodiment of the present invention, and FIG. 1 (b) shows the light irradiation region formed on the surface of the irradiation target by the animal repellant device. It is a figure which shows a pattern.

  The animal repellent device 10 shown in FIG. 1A and FIG. 1B is a plate having a light source 11 for irradiating a laser beam L and a diffraction grating 12 for changing the traveling direction of the laser beam L emitted from the light source. The member 13 is provided. The plate-shaped member 13 is attached to the main body 15 via the rotation mechanism 14, and the main body 15 is installed on the ceiling S using the attachment member 16. By rotating the plate member 13 by the rotating mechanism 14, the relative position of the diffraction grating 12 with respect to the light source 11 can be changed. As a result, the position of the light irradiation area SP1 on the floor surface F of the laser light that has passed through the diffraction grating 12 can be changed.

  FIG. 1A shows a case where the animal repellent device 10 is provided so that the optical axis Ax of the laser light emitted from the light source 11 is parallel to the Y axis. In this case, the plate-shaped member 13 of the animal repellent device 10 rotates about a direction parallel to the optical axis Ax (Y axis) as a rotation axis while maintaining its surface parallel to the XZ plane. The relationship between the optical axis Ax, the rotation axis of the plate member 13, and the Y axis is not limited to this. The animal repellent device 10 may be provided so that the optical axis Ax of the laser light intersects the Y axis, and the plate member 13 may be provided so that the rotation axis is not parallel to the optical axis Ax.

  The plate-like member 13 is provided with the diffraction grating 12 in a region where the laser light L passes. Therefore, the laser light L emitted from the light source 11 passes through the diffraction grating 12 to form a pattern of the light irradiation area SP1 on the floor surface F which is an irradiation target. Here, the "pattern" refers to the light irradiation area SP1 formed on the surface (XZ plane) of the floor surface F so as to spread two-dimensionally, that is, in both the X-axis direction and the Z-axis direction. Therefore, for example, the light irradiation area SP1 including only one straight line is not included in the “pattern”.

  FIG. 1B shows an example in which the light irradiation area SP1 is evenly spread in the X-axis direction and the Y-axis direction, but the pattern may not be evenly spread. However, from the viewpoint of exhibiting the animal repellent effect in a wide range, a pattern that is evenly spread is preferable. For example, the width (WX) in the X-axis direction, the width (WY) in the Y-axis direction, and the aspect ratio (WX / WY) in the light irradiation region SP1 are preferably about 0.5 to 2.

  FIG. 2A is a diagram showing a structure of a main part of the animal repellent device, and FIG. 2B is a diagram showing how the light irradiation region SP1 formed on the surface of the irradiation target object by the animal repellent device moves. is there. In FIG. 2B, the locus of movement of the pattern in the light irradiation area SP1 is indicated by a white circle.

  When the plate member 13 is rotated by the rotating mechanism 14, the relative position of the diffraction grating 12 with respect to the light source 11 changes. As a result, the position of the light irradiation area SP1 on the floor surface F moves to form a locus as shown in FIG. 2B, for example. It suffices that the diffraction grating 12 be provided in a region through which the laser light passes, and it is not necessary to provide the whole of the plate member 13.

  By moving the floor surface F so that the pattern of the light irradiation area SP1 forms a locus, the animal can be effectively repelled. The animals to be repelled include not only mammals such as mice and moles and birds such as crows, but also insects such as cockroaches and flies and arthropods including spiders. When the light irradiation area SP1 moves around the floor F, the animal to be repelled mistakenly recognizes the light irradiation area SP1 as its predator or extermination object, and it becomes difficult to approach the floor F.

  Further, the plate member 13 provided with the diffraction grating 12 can be easily configured with a small and light member. Therefore, the load on the rotation mechanism 14 when moving the position of the light irradiation area SP1 on the floor F is reduced. Therefore, it is useful for increasing the durability and reliability of the animal repellent device 10. Moreover, the animal repellent device 10 can be downsized by using the plate-shaped member 13 provided with the diffraction grating 12.

  The light irradiation area SP1 does not need to move the entire movable area (moving area) shown in FIG. For example, the light irradiation area SP1 may move a part of the movement area by blinking the light source 11. If this blinking is performed irregularly, it may be difficult for the animal to be repelled to notice that the light irradiation region SP1 moves only in the region, and the effect of repelling the animal may be enhanced.

  The animal repellent device 10 according to the present embodiment may further include a housing that surrounds the light source 11 and the plate member 13 in a state capable of emitting the laser light L. Since it is possible to prevent light leaking from the light source 11 by the housing, it is possible to prevent a light-collecting animal (such as an insect) from approaching the animal repellent device 10.

(Second embodiment)
The animal repellent device 10A of the present embodiment includes a diffraction grating (first diffraction grating) 12A and a diffraction grating (second diffraction grating) in which patterns formed by the light irradiation areas of the plate-shaped member 13 having passed through the diffraction grating are different. 1 and the two light sources 11 are provided, and the animal repellent device 10 shown in FIG. 1 is different.

  FIG. 3A is a diagram showing a main part structure of an animal repellent device according to another embodiment of the present invention, and FIG. 3B is a light irradiation region formed on the surface of an irradiation target by the animal repellent device. It is a figure which shows the pattern of.

  As shown in FIG. 3A, a different pattern is obtained when the laser light from the light source 11 passes through the diffraction grating 12A and when the laser light from the light source 11 passes through the diffraction grating 12B. (See FIG. 1). In FIG. 3B, as an example, the light irradiation area SP1 forms a pattern in which small dots are arranged in a radial pattern, and the light irradiation area SP2 forms a pattern in which four rings are evenly arranged. By rotating the plate member 13 by the rotating mechanism 14, the pattern of the light irradiation area SP1 and the pattern of the light irradiation area SP2 move on the floor surface F.

  In this way, by providing the diffraction grating 12A and the diffraction grating 12B in each region facing each light source 11, different patterns can be simultaneously formed on the floor surface F. Thereby, the repellent effect of animals can be improved.

  Further, the diffraction grating 12A and the diffraction grating 12B may be designed so that the light irradiation area SP1 and the light irradiation area SP2 move on different trajectories. This complicates the movement of the pattern of the laser light L on the floor surface F, so that the repellent effect on the repellent target animal can be enhanced. In the present embodiment, the example in which the two light sources 11 are configured by the same one has been described, but one that emits laser beams having different wavelengths may be used.

(Third Embodiment)
The animal repellent device 10B of the present embodiment is provided with two light sources 11A and two light sources 11B that emit laser beams having different wavelengths, two in total, that is, a total of four light sources. It is different from 10A.

  The light source 11A and the light source 11B emit laser light of different wavelengths (colors), and one of the laser light emitted from the two light sources 11A can pass through the diffraction grating 12A while the other is diffracted. It is configured to be able to pass through the grid 12B. Also, the laser light L emitted from the two light sources 11B is configured such that the other one can pass through the diffraction grating 12A while the other one can pass through the diffraction grating 12A, like the laser light L emitted from the light source 11A. Has been done.

  FIG. 4 (a) is a diagram showing a main structure of the animal repellent device 10B according to the present embodiment, and FIG. 4 (b) shows the animal repellent device 10B formed on the surface of the floor surface F (see FIG. 1). It is a figure which shows the pattern of the light irradiation area | region SP1 and the light irradiation area | region SP2 which do.

  As shown in FIG. 4A, the light source 11A and the light source 11B are provided one by one at positions where the laser light that has passed through the diffraction grating 12A can be emitted. Also, one light source 11A and one light source 11B are provided at positions where the laser light that has passed through the diffraction grating 12B can be emitted. With this configuration, both the diffraction grating 12A and the diffraction grating 12B can selectively emit laser light from the light source 11A or the light source 11B.

  With respect to each of the diffraction grating 12A and the diffraction grating 12B, depending on which of the light source 11A and the light source 11B emits the laser light, the laser light and the patterns shown in FIGS. 4B and 5A to 5C are formed. The four combinations with and can be easily changed. Thereby, the repellent effect can be enhanced by selecting a combination suitable for the repellent target animal, and the repellent effect can be maintained for a long time by using various patterns.

  In the above-described embodiment, the mode in which only the light source that emits the laser light is used has been described, but in addition to the light source that emits the laser light, a light source that emits light other than the laser light may be used together. Examples of such a light source include an LED lamp. By using a light source that emits laser light and an LED lamp in combination, it is possible to further diversify the irradiation pattern.

  As described above, according to the present invention, for example, it is possible to provide an animal repellent device that surprises the extent to which an indoor animal cannot stay indoors or enter an outdoor cultivated land. It will be possible.

(Fourth Embodiment)
In this embodiment, an animal repellent method using the above-described animal repellent device of the present invention will be described.
FIG. 6 is a diagram illustrating an embodiment of the indoor animal evasion method according to the present embodiment. The animal repellent method of the present embodiment is a method in which the animal repellent device 10 is attached to the ceiling S and the animal repellent device 10 displaces the laser light irradiation region SP1 formed on the floor surface F. Although FIG. 6 shows an example in which the animal repellent device 10 is attached to the ceiling S, the animal repellent device of the present embodiment can be implemented by attaching the animal repellent device 10 to the wall surface W.

  By changing the relative position between the light source 11 and the diffraction grating 12, the light irradiation area SP1 based on the light source 11 formed on the floor surface F or the wall surface W moves within a predetermined area (see FIG. 2) and FIG. 2B), animals in the room can be repelled.

  FIG. 7: is a figure explaining the embodiment of the animal repellent method of irradiating the indoor arrangement object 20 with light. For the convenience of cleaning, kitchens, counters, and appliances made of stainless steel are often used in kitchens of restaurants, which are places where it is particularly necessary to avoid animals. By irradiating the indoor placement object 20 made of stainless with the laser light L and changing the position by the animal repellent device, the light irradiation area SP2 of the reflected laser light LR reflected from the indoor placement object 20 is also displaced. . According to this method, the laser light LR reflected from the surface of the indoor placement object 20 reaches the wall surface W and the ceiling S, and the irradiation area SP2 can be displaced simultaneously with the irradiation area SP1 of the laser light L. When the light irradiation areas SP1 and SP2 move on the surface of the indoor placement object 20, the floor surface F, the wall surface W, or the ceiling S, the repellent target animal falls into a panic state. Moreover, when the light irradiation areas SP1 and SP2 are formed not only on the floor surface F but also on the wall surface W and the ceiling S, the repellent target animal recognizes that the escape route has been cut off, and becomes further confused. For this reason, it may be caught by a sticky animal catching device that can be easily avoided under normal circumstances.

  When used indoors, the wall DR may be provided with a door DR that can be moved only indoors to outdoors. In this case, the animal can escape to the outside from the door DR while the animal repellent device 10B is operating, and the trouble of capturing the animal is unnecessary. As described above, if the indoor animal excluding device is configured by the animal repelling devices 10, 10A, and 10B and the door DR that can only be moved from the indoor to the outdoor, the indoor animals can be efficiently excluded. it can.

  In the above-described embodiment, the mode in which the animal repellent device is mainly used indoors has been described, but the animal repellent device can also be used outdoors.

  Although the respective embodiments of the present invention have been described above, the present invention is not limited to these examples. Those skilled in the art appropriately add, delete, and change the design of the above-described embodiments, and those that appropriately combine the features of the configuration examples of the respective embodiments also have the gist of the present invention. As long as it is present, it is included in the scope of the present invention.
