Summary of the Invention

Problems to be Solved by the Invention

[0004] In any of the insect trapping devices disclosed in the above patent documents, approximately half of the device is embedded in the wall and the remaining part is installed in a form exposed from the wall surface, so it is considered that the aesthetics of the interior may be impaired. Further, even if the entire insect trapping device is embedded in the wall, in order to release the air containing the attractant to the indoor side, it is necessary to secure an opening for releasing the air by sinking a part of the wall surface or install a duct communicating with the indoor side in the wall, so the aesthetics of the interior will still be impaired.

[0005] An object of the present invention is to provide an insect trapping device that can capture insects more efficiently without impairing the aesthetics of the interior.

Embodiments for Carrying Out the Invention

[0009] Hereinafter, embodiments of the insect-catching device according to the present invention will be described. Note that all the drawings attached to this specification are schematic diagrams, and in consideration of ease of understanding, etc., the shape, scale, vertical and horizontal dimensional ratios, etc. of each part are changed or exaggerated from the actual object. Also, in the drawings, for example, hatching indicating the cross-section of a wall or a plate material is appropriately omitted.

[0010] In this specification and the like, with respect to terms specifying shape, geometric conditions, and degrees thereof, such as terms like "orthogonal" and "direction", in addition to the exact meaning of the term, it includes a range that can be regarded as approximately orthogonal and a range that can be regarded as generally in that direction.

[0011] Also, in each of the figures shown below, for the sake of easy explanation and understanding, an orthogonal coordinate system of XYZ is appropriately provided. In this coordinate system, when viewing the insect-catching device 1 embedded in the wall surface from the front, the left-right direction is the X (X1 - X2) direction, the up-down direction is the Y (Y1 - Y2) direction, and the front-back direction is the Z (Z1 - Z2) direction. In this specification, "~ direction" is also appropriately referred to as "~ side". Also, in this specification, for example, the same direction names such as "front side Z1" are appropriately replaced with other names such as "indoor side Z1" for description.

[0012] FIG. 1 is an external view of the insect-catching device 1 according to the embodiment. FIG. 2 is a cross-sectional view when viewing the insect-catching device 1 embedded in the wall surface from the left side X1. FIGS. 3(A) and (B) are diagrams for explaining the configuration of the front plate portion 16 and the hinge 18. FIG. 4 is a diagram for explaining the configuration of the support portion 20. Note that the directions of each part shown in FIGS. 3 and 4 conform to FIG. 2.

[0013] The insect-catching device 1 is a device for capturing flying insects such as mosquitoes, moths, and flies, as well as creeping or wandering insects and arthropods (hereinafter also referred to as "insects"). The insect-catching device 1 is, for example, used by being embedded in a wall surface in an indoor environment such as a residence, an office, a restaurant, or a hotel guest room. As will be described later, the insect-catching device 1 can be used not only embedded in a wall surface but also embedded in a floor surface or a ceiling surface. In this specification, "wall surface" means, in addition to the surface of the wall, including the inner part of the wall. The same applies to "floor surface" and "ceiling surface".

[0014] As shown in Fig. 1, the insect-catching device 1 includes a housing 10, a support portion 20, and a light source 30. Also, as shown in Fig. 2, the insect-catching device 1 is embedded in the wall such that the front side (indoor side) Z1 of the housing 10 is substantially flush with the wall surface W. In Fig. 1, the illustration of the hinge 18, the insect-catching sheet 40, etc. is omitted. Also, although not shown, electrical wiring is embedded inside the wall surface where the insect-catching device 1 is installed. The light source 30 described later is supplied with power from the electrical wiring embedded in the wall.

[0015] (Housing 10) As shown in Fig. 1, the housing 10 is a box-shaped structure having a space inside. The housing 10 of the embodiment is configured in a box shape that is long in the left-right direction X. The housing 10 includes a bottom plate portion 11, a top plate portion 12, a right side plate portion 13, a left side plate portion 14, a back plate portion 15, and a front plate portion 16. The above-described portions of the housing 10 are made of, for example, wood, plastic, metal, or a composite material thereof. The above-described portions of the housing 10 may be made of the same material or may be partially made of different materials. Also, in the housing 10, the portions other than the front plate portion 16 may be integrally formed as a box-shaped structure.

[0016] The bottom plate portion 11 is a plate member disposed on the bottom surface (the surface on the Y2 side) of the housing 10. The support portion 20 and the hinge 18 (not shown) described later are provided on the bottom plate portion 11. The top plate portion 12 is a plate member disposed on the top surface (the surface on the Y1 side) of the housing 10. The right side plate portion 13 and the left side plate portion 14 are plate members disposed on the right side surface (the surface on the X2 side) and the left side surface (the surface on the X1 side) of the housing 10, respectively. The back plate portion 15 is a plate member disposed on the back surface (the surface on the Z2 side) of the housing 10. The light source 30 (described later) is provided on the back plate portion 15.

[0017] The front plate portion 16 is a plate member disposed on the front surface (the surface on the Z1 side) and the lower side Y2 of the housing 10, and is configured to be openable and closable toward the indoor side Z1. As shown in FIG. 2, the front plate portion 16 is configured to have a shorter dimension in the vertical direction Y than other plate materials. Therefore, in the state shown in FIG. 2 with the front plate portion 16 closed, an opening 17 that opens toward the indoor side Z1 is formed above the front plate portion 16 on the upper side Y1. The opening 17 is a portion where insects attracted by the light of the light source 30 enter the insect trapping device 1, and as shown in FIG. 1, it extends in the left-right direction X. When the insect trapping device 1 is embedded in the indoor wall surface, the height from the floor surface to the opening 17 is, for example, about 180 to 200 cm. Also, as will be described later, it is desirable to appropriately set the vertical position of the light source 30 in the housing 10 according to the height from the floor surface to the opening 17.

[0018] As shown in FIG. 2, the same wallpaper WP as the wall surface W is pasted on the indoor side Z1 of the front plate portion 16. Thereby, in the state where the front plate portion 16 is closed, the front side Z1 of the front plate portion 16 is visually integrated with the wall surface W, so that the aesthetics of the interior are not impaired when the insect trapping device 1 is in use. Therefore, it is possible to make it difficult to give the user a sense of discomfort. Note that a design different from the wallpaper WP may be applied to the front side Z1 of the front plate portion 16. Also, for drawings other than FIG. 2, the illustration of the wallpaper WP is omitted.

[0019] Hinges 18 (not shown in FIG. 1) are attached to both ends of the front plate portion 16 in the left-right direction X. The hinge 18 is a component that supports the front plate portion 16 so as to be openable and closable toward the indoor side Z1. As shown in FIG. 3(A), the main body portion 18a of the hinge 18 is attached to the bottom plate portion 11. Also, the hinge portion 18b of the hinge 18 is attached to the front plate portion 16. Note that the mechanism for supporting the front plate portion 16 so as to be openable and closable is not limited to the hinge 18, and other mechanisms can also be applied. For example, a slide mechanism may be used to configure the front plate portion 16 to be horizontally inserted and removed in the front-rear direction Z of the housing 10. Also, in the front plate portion 16, a hinge may be attached to one side surface in the left-right direction X, and a simple locking mechanism may be provided on the other side surface, and the front plate portion 16 may be rotated horizontally to be opened and closed.

[0020] As shown in FIG. 3(A), when the front plate portion 16 is closed, the front side of the front plate portion 16 is substantially flush with the wall surface W. On the other hand, as shown in FIG. 3(B), when the front plate portion 16 is opened to the front side Z1, the front plate portion 16 is in a state of being rotated approximately 90° to the front side Z1 with respect to the wall surface W. As a result, an opening 19 (see FIG. 2) communicating with the opening 17 is formed on the indoor side Z1 of the housing 10. Therefore, the administrator can easily perform the replacement of the insect-catching sheet 40 and the maintenance of the light source 30 by opening the front plate portion 16 of the insect-catching device 1 to the indoor side Z1. Note that the angle at which the front plate portion 16 opens with respect to the wall surface W is not limited to approximately 90°, and any angle may be used as long as the replacement of the insect-catching sheet 40 and the maintenance of the light source 30 can be performed.

[0021] (Support portion 20) Returning to FIG. 1, the support portion 20 is a member that supports the insect-catching sheet 40 (described later). As shown in FIG. 1, the support portions 20 are respectively arranged on both end sides in the left-right (width) direction X of the housing 10. The support portion 20 supports the insect-catching sheet 40 such that the first adhesive surface (described later) of the insect-catching sheet 40 and the second adhesive surface 42 (described later) are respectively exposed. Specifically, the support portion 20 supports the insect-catching sheet 40 such that the first adhesive surface 41 is exposed toward the opening 17 of the housing 10 and the second adhesive surface 42 is exposed toward the side opposite to the opening 17.

[0022] The support portion 20 is provided on the front side Z1 of the light source 30 (described later) in the front-rear direction Z of the housing 10. Since the insect-catching sheet 40 to be mounted on the support portion 20 has adhesive surfaces on both sides, it is desirable to provide the insect-catching sheet 40 at a position in the housing 10 where appropriate insect-catching spaces are formed on the front side Z1 and the rear side Z2 of the insect-catching sheet 40.

[0023] In the embodiment, since the configurations of the support portions 20 on the left and right are the same, here, the configuration of the support portion 20 provided on the left side X1 of the housing 10 will be described as an example. As shown in FIG. 4, the support portion 20 includes a support column 21 and a base portion 22. The support column 21 is a rod-shaped member around which the insect-catching sheet 40 is wound. The length of the support column 21 varies depending on the height from the floor surface of the insect-catching device 1 and the type of insects, but it is preferably longer than the width of the insect-catching sheet 40 to be attached.

[0024] The base portion 22 is a portion that supports the support column 21 so as to be tiltable toward the front side Z1 and the rear side Z2 of the housing 10. The lower end portion Y2 of the support column 21 is rotatably attached to the shaft 23 of the base portion 22. The lower end portion Y2 of the support column 21 is supported by the shaft 23 with an appropriate fastening force. Therefore, when the operator manually tilts the support column 21, the angle of the support column 21 is maintained in that state. The base portion 22 may be configured to be replaceable with support columns 21 of different lengths so as to be able to accommodate insect-catching sheets 40 having different widths (in the short side direction).

[0025] The base portion 22 is provided with a scale 24 indicating the tilt angle of the support column 21. As shown in FIG. 4, in the embodiment, the scale 24 is provided at 5° intervals within a range of 40° clockwise and 40° counterclockwise around the shaft 23. In FIG. 4, the support column 21 rotated 40° clockwise and the support column 21 rotated 40° counterclockwise are each indicated by imaginary lines (two-dot chain lines), but the range in which the support column 21 is rotated is not limited to the illustrated example. The range of the scale 24 provided on the base portion 22 is not limited to the example of the embodiment. Further, the support column 21 may be tilted further beyond the range of the scale 24.

[0026] The insect-catching sheet 40 is an adhesive sheet for catching insects. The insect-catching sheet 40 has adhesive surfaces (adhesive layers) on both sides. When in use, the first adhesive surface 41 is formed on the first surface that becomes the indoor side Z1, and the second adhesive surface 42 is formed on the second surface opposite to the first surface. Note that the first surface and the second surface are opposite to each other. That is, if the indoor side Z1 is the first surface, the opposite side is the second surface, and if the indoor side Z1 is the second surface, the opposite side is the first surface. Therefore, when the insect-catching sheet 40 is in use, the adhesive surface that becomes the indoor side Z1 may be the first adhesive surface 41 or the second adhesive surface 42. The adhesive strengths of the adhesive surfaces formed on the first surface and the second surface of the insect-catching sheet 40 may be the same or different. Also, as will be described later, the insect-catching sheet 40 may have an adhesive surface on one side only.

[0027] The insect-catching sheet 40 may have light transmissibility (transparent, translucent, etc.) or may be colored yellow, blue, etc. The insect-catching sheet 40 is mounted so as to be spanned between a pair of support portions 20 arranged on both end sides in the left-right direction X of the insect-catching device 1. Before being mounted on the support portion 20, the insect-catching sheet 40 is wound in a roll shape, for example, with a release paper laminated on one side. Note that in FIG. 4 and FIGS. 5(A) to (D) described later, the thickness of the insect-catching sheet 40 is exaggeratedly drawn.

[0028] Next, the procedure for mounting the insect-catching sheet 40 on the support portion 20 will be described. FIGS. 5(A) to (D) are diagrams for explaining the procedure for mounting the insect-catching sheet 40 on the support portion 20. FIGS. 5(A) to (D) are plan views when the support portion 20 is viewed from the upper side Y1 to the lower side Y2 in the vertical direction Y. In FIGS. 5(A) to (D), only the column 21 of the support portion 20 is shown.

[0029] First, as shown in FIG. 5(A), the insect-catching sheet 40 is supported such that the second adhesive surface 42 faces the side of the pair of support portions 20, and both end sides of the insect-catching sheet 40 are attached to the columns 21 of the pair of support portions 20. It is desirable to cut the insect-catching sheet 40 in advance so that the length in the left-right direction X is about several centimeters longer than the interval between the pair of columns 21.

[0030] Next, as shown in FIG. 5(B), the surplus portions on both end sides of the insect-catching sheet 40 are folded back toward the second adhesive surface 42 and attached to the second adhesive surface 42. Next, as shown in FIG. 5(C), the release paper 43 is peeled off from the insect-catching sheet 40. As a result, as shown in FIG. 5(D), the insect-catching sheet 40 with the first adhesive surface 41 and the second adhesive surface 42 exposed can be mounted so as to span between the pair of support portions 20.

[0031] Note that in FIGS. 5(A) to 5(D), an example of mounting the insect-catching sheet 40 from the front side Z1 of the support portion 20 is shown, but the insect-catching sheet 40 may be mounted from the rear side Z2 of the support portion 20. Further, when replacing the insect-catching sheet 40, for example, it can be removed by cutting the insect-catching sheet 40 with scissors, a cutter, etc. in the vicinity of the support portion 20.

[0032] (Light source 30) Returning to FIG. 1, the light source 30 is a light-emitting device that emits light having a wavelength for attracting insects and functions as an attracting portion for attracting insects into the housing 10. The light source 30 of the embodiment is composed of a plurality of LEDs (not shown) arranged in a line. That is, the light source 30 of the embodiment extends along the left-right (width) direction X of the housing 10. The light source 30 is not limited to the LEDs of the embodiment, and may be composed of, for example, a fluorescent lamp, an incandescent bulb, etc. The light source 30 of the embodiment is provided on the back plate portion 15 in the housing 10. That is, the light source 30 is provided on the rear side Z2 rather than the support portion 20. The position of the light source 30 in the vertical direction Y is appropriately set according to the height from the floor surface on which the insect-catching device 1 is installed. Note that the light source 30 may be installed on the back plate portion 15 or may be installed on the bottom plate portion 11.

[0033] The light source 30 is preferably positioned such that the light does not directly enter the user's eyes regardless of the height at which the insect-catching device 1 is installed. For example, when the insect-catching device 1 is installed at a position 100 cm from the floor surface, it is considered that the user often views the insect-catching device 1 from below the line of sight, i.e., in the lower side Y2. Therefore, the light source 30 is preferably provided at a position close to the bottom plate portion 11. When the insect-catching device 1 is installed at a position 180 cm from the floor surface, it is considered that the user often views the insect-catching device 1 at a position approximately the same as the line of sight or slightly above the line of sight, i.e., in the upper side Y1. Therefore, the light source 30 is preferably provided at a position slightly below the opening 17. When the insect-catching device 1 is installed at a position 200 cm from the floor surface, it is considered that the user often views the insect-catching device 1 above the line of sight, i.e., in the upper side Y1. Therefore, the light source 30 is preferably provided at a position approximately the same as the opening 17.

[0034] According to the insect-catching device 1 of the above-described embodiment, for example, the following effects can be obtained. The insect-catching device 1 of the embodiment is used by being embedded in a wall such that the front side Z1 of the housing 10 is substantially flush with the wall surface W. Also, in the insect-catching device 1, there is no need to create an opening for discharging air by sinking a part of the wall surface or to install a duct communicating with the indoor side in the wall. Therefore, in the insect-catching device 1 of the embodiment, the aesthetics of the interior are not impaired.

[0035] Further, the insect-catching device 1 of the embodiment includes a support portion 20 that supports the insect-catching sheet 40 such that the first adhesive surface 41 and the second adhesive surface 42 of the insect-catching sheet 40 are exposed, and an attracting portion (light source 30) for attracting insects into the housing 10. According to this configuration, since the insects attracted into the housing 10 can be captured on both sides of the insect-catching sheet 40, compared to an insect-catching device configured to capture insects only on one side of the insect-catching sheet, the insects attracted into the housing 10 can be captured more efficiently. Therefore, according to the insect-catching device 1 of the embodiment, insects can be captured more efficiently without impairing the aesthetics of the interior.

[0036] The insect-catching device 1 of the embodiment includes a light source 30 as an attracting unit for attracting insects into the housing 10. Therefore, by emitting light of a wavelength that attracts insects from the light source 30, insects can be attracted more efficiently. Also, the light emitted from the light source 30 can be used as indirect lighting in the room.

[0037] In the insect-catching device 1 of the embodiment, the light source 30 extends along the left-right (width) direction X of the housing 10. Therefore, the insect-catching device 1 can irradiate light more uniformly from the opening 17. Also, when the light emitted from the light source 30 is used as indirect lighting in the room, a wider range of the room can be illuminated.

[0038] In the insect-catching device 1 of the embodiment, the support portions 20 are respectively arranged on both end sides in the left-right (width) direction X of the housing 10. Therefore, in the insect-catching device 1, the insect-catching sheet 40 can be mounted so as to be spanned between the pair of support portions 20. Also, according to this configuration, the insect-catching sheet 40 can be mounted to an appropriate length in accordance with the length in the left-right (width) direction X of the opening 17 of the housing 10.

[0039] In the insect-catching device 1 of the embodiment, the support portion 20 supports the insect-catching sheet 40 such that the first adhesive surface 41 is exposed toward the opening 17 of the housing 10 and the second adhesive surface 42 is exposed toward the side opposite to the opening 17. Therefore, according to the insect-catching device 1, the capture rate of insects that have entered from the opening 17 of the housing 10 on the first adhesive surface 41 can be increased. Also, the capture rate of insects that have entered the side opposite to the opening 17 (the back side) on the second adhesive surface 42 can be increased.

[0040] In the insect trap 1 of the embodiment, the support portion 20 to which the insect trapping sheet 40 is attached is configured to be tiltable toward either the front side Z1 or the rear side Z2 of the housing 10. According to this configuration, inside the housing 10, when an insect that has moved to the side where the insect trapping sheet 40 is tilted exits the housing 10, the insect trapping sheet 40 covers the flying direction of the insect, making it easier to capture the insect. Thus, by tilting the support portion 20 toward either the front side Z1 or the rear side Z2, not only when an insect attracted by light enters the housing 10, but also when an insect exits the housing 10, it becomes easier to capture the insect, so that the capture rate of the insect can be further increased.

[0041] In the insect trap 1 of the embodiment, it is known that the types of insects that can be captured by the insect trapping sheet 40 attached to the support portion 20 differ depending on the color and light transmittance of the sheet. A variety of insect trapping sheets 40 with different colors and light transmittances can be attached to the support portion 20 of the embodiment. For example, in the case of an insect that is easy to capture by using a transparent insect trapping sheet 40, the support portion 20 with the transparent insect trapping sheet 40 attached can be tilted toward the rear side Z2 so that the insect trapping sheet 40 covers the light source 30. Thereby, since light is irradiated through the transparent insect trapping sheet 40, the capture rate of the target insects can be further increased.

[0042] In the insect trap 1 of the embodiment, the support portion 20 has a scale 24 indicating the tilt angle of the support column 21. Therefore, by recording the relationship between the tilt angle of the support column 21 to which the insect trapping sheet 40 is attached and the insect capture rate, the most efficient conditions can be specified according to the installation location of the insect trap 1, the type of insects, etc.

[0043] In the insect trap 1 of the embodiment, the housing 10 includes a front plate portion 16 that can be opened and closed toward the indoor side Z1. By opening the front plate portion 16, an opening 19 communicating with the opening 17 is formed on the front side Z1 of the housing 10. According to this configuration, the administrator can easily replace the insect trapping sheet 40 and perform maintenance on the light source 30 by opening the front plate portion 16 of the insect trap 1 toward the front side Z1.

[0044] (Modification) As described above, the embodiments of the present invention have been explained. However, the present invention is not limited to the above-described embodiments, and various modifications and changes are possible as in the modification forms described below, and these are also included within the technical scope of the present disclosure. Also, the effects described in the embodiments are merely an enumeration of the most suitable effects resulting from the present disclosure and are not limited to those described in the embodiments. Note that the above-described embodiments and the modification forms described below can be used in appropriate combination, but detailed explanations are omitted.

[0045] FIG. 6 is a conceptual diagram showing the interior (indoors) of a room in a building. In FIG. 6, the building 50 is, for example, a house, an office building, or the like. As shown in FIG. 6, the room 51 includes wall surfaces 52 to 54, a floor surface 55, and a ceiling surface 56 inside. Note that in FIG. 6, the wall surface on the front side in the figure is omitted. In the above-described embodiment, an example in which the insect-catching device 1 is embedded in a wall surface (for example, the wall surface 53) as shown in region A of FIG. 6 has been described, but it is not limited to this. For example, as shown in region B of FIG. 6, the insect-catching device 1 may be embedded in the floor surface 55 or used, or as shown in region C of FIG. 6, it may be embedded in the ceiling surface 56 and used. When the insect-catching device 1 is embedded in the ceiling surface 56 and used, it may be installed near the lighting fixture or at a position away from the lighting fixture.

[0046] Also, as shown in region D of FIG. 6, the insect-catching device 1 may be embedded in the wall surface 53 such that the longitudinal direction is along the vertical direction Y. In the configuration in which the insect-catching device 1 is embedded in the floor surface 55 (see region B) or the wall surface 53 (see region D), in order to prevent the light from the light source from directly entering the eyes of the user, as shown in FIG. 6, it is desirable to embed the insect-catching device 1 along the wall.

[0047] In the insect trap 1 of the embodiment, the light emitting surface of the light source 30 may be configured to be movable in the vertical direction Y, and the irradiation angle of the light may be manually adjusted according to the usage conditions of the insect trap 1. Further, a drive mechanism for moving the light emitting surface of the light source 30 in the vertical direction Y may be provided so that the irradiation angle of the light can be adjusted by remote control according to the usage conditions of the insect trap 1. With the above configuration, for example, during the bright daytime hours, the light from the light source 30 can be adjusted to face the opening 17, and during the dark nighttime hours, the light from the light source 30 can be adjusted so as not to directly face the opening 17, so that the opening 17 is irradiated with reflected light.

[0048] In the insect trap 1 of the embodiment, a plurality of light sources 30 may be arranged along the vertical direction Y of the housing 10, and the light source 30 to be lit may be selected according to the usage conditions. In the insect trap 1 of the embodiment, a flap (louver) movable in the vertical direction Y may be provided above the light source 30 in the Y1 direction, and the irradiation range of the light source 30 may be adjusted according to the usage conditions.

[0049] In the insect trap 1 of the embodiment, the shape of the housing 10 is not limited to a box shape that is long in the left-right direction X as shown in FIG. 1, and may be a box shape in which the length in the left-right direction X and the length in the vertical direction Y are substantially equal. That is, the housing 10 may have any shape as long as the support portion 20 and the light source 30 can be appropriately installed.

[0050] In the embodiment, an example in which the light source 30 is provided as the attracting portion has been described, but the present invention is not limited to this. The attracting portion may be a chemical storage portion having a chemical (attractant) preferred by insects. In the chemical storage portion, insects can be attracted by releasing air containing the chemical from the opening 17 into the room. Further, the attracting portion may be a device that emits a gas containing a component preferred by insects, or a device that emits a sound in a frequency band preferred by insects.

[0051] In the embodiment, an example in which the support column 21 of the support portion 20 is supported so as to be tiltable toward the front side Z1 and the rear side Z2 has been described, but the present invention is not limited thereto. The support column 21 may be configured to be tiltable only toward the front side Z1, or the support column 21 may be configured to be tiltable only toward the rear side Z2. Further, in the support portion 20, the support column 21 may be fixed at a specific tilt angle (for example, an angle orthogonal to the plate surface of the bottom plate portion 11).

[0052] In the embodiment, an example in which the support portions 20 that support the insect-catching sheet 40 are respectively arranged on both end sides in the left-right (width) direction X of the housing 10 has been described, but the present invention is not limited thereto. The support portion 20 may be provided on either one of the end sides in the left-right direction X of the housing 10. For example, the support portion 20 may be provided on the end side in the left direction X1 of the housing, and the end in the right direction X2 of the insect-catching sheet 40 may be directly attached to the right side plate portion 13 of the housing 10. Further, if there is no interference with the light source 30, a plurality of support portions 20 may be arranged along the front-rear direction Z.

[0053] In the embodiment, an example in which the insect-catching sheet 40 having adhesive surfaces formed on the first surface and the second surface has been described, but the present invention is not limited thereto. The insect-catching sheet 40 having an adhesive surface formed only on the first surface may be used, or the insect-catching sheet 40 having an adhesive surface formed only on the second surface may be used. When an adhesive surface is formed on one side of the insect-catching sheet 40, for example, by using the insect-catching sheet 40 having an adhesive surface (second adhesive surface 42) formed on the second surface on the side of the light source 30, the capture rate of insects attracted by the light of the light source 30 can be increased. Further, as described above, in the case of insects that are easy to capture by using the transparent insect-catching sheet 40, by using the transparent insect-catching sheet 40 having an adhesive surface (first adhesive surface 41) formed on the first surface on the indoor side, the capture rate of insects flying toward the light irradiated through the insect-catching sheet 40 can be increased.

[0054] In the embodiment, an example in which one insect-catching sheet 40 is mounted between a pair of support portions 20 has been described, but the present invention is not limited thereto. Two support columns 21 may be provided on each support portion 20 (for example, V-shaped in the side view of FIG. 2), and two insect-catching sheets 40 may be mounted between the pair of support portions 20. The number of support columns 21 provided on one support portion 20 is not limited to 1 or 2, and may be three or more. Further, the shape of the support column 21 may be, for example, L-shaped in the side view. In that case, two insect-catching sheets 40 can be mounted between a pair of support portions 20 each having one support column 21. Furthermore, the shape of the support column 21 is not limited to a rod shape (I-shaped), and may be a polygon such as a △ shape or a □ shape in the side view. In that case, three or more insect-catching sheets 40 can be three-dimensionally mounted between a pair of support portions 20 each having one support column 21.

[0055] In the embodiment, an example in which the light source 30 is constituted by a plurality of LEDs arranged in a line has been described, but the present invention is not limited thereto. The light source 30 may be a dot-shaped light source, or may be configured such that a plurality of dot-shaped light sources are intermittently arranged along the left-right direction X.

[0056] In the insect-catching sheet 40 of the embodiment, the adhesive material may contain an attractant. For example, by using an insect-catching sheet containing a human-derived attractant as the attractant, the capture ability of insects having positive (the property of being attracted to light) phototaxis and being likely to react to the attractant can be further enhanced. Note that as the insect-catching sheet, it is desirable to use a dedicated product having an appropriate adhesive strength, but a commercially available double-sided tape can also be used as long as it has an equivalent adhesive strength.
