  In addition, a power switch 112 that switches ON / OFF of energization to the light emitter 113 is provided on a side surface of the main body 111. That is, the main body 111 is connected to an external power source (not shown) (for example, a 100 V outlet) and turns on and off the light emitter 113 by electricity supplied from the external power source.

  The light emitter 113 is an electric appliance that emits light having a wavelength capable of attracting pests as attracting light. Specifically, the light emitter 113 is generally known to have a wavelength of light capable of attracting pests of approximately 250 nm to 600 nm. Therefore, depending on the type of pest to be controlled, light having a single wavelength or different wavelengths is used. It is configured by appropriately combining light sources that emit light. In the present embodiment, the light emitter 113 is constituted by a fluorescent lamp that emits light with a near-ultraviolet ray of 352 nm as a peak wavelength.

  Two sheet holders 130 are supported via support arms 120 along the longitudinal direction of the attracting light generating unit 110 on both sides (the left-right direction in the drawing) orthogonal to the longitudinal direction of the attracting light generating unit 110. The support arm 120 is a member for movably supporting the sheet holder 130 at the both side positions in the vicinity of the attraction light generation unit 110 and extends from the main body 111 of the attraction light generation unit 110 to both sides. Is formed. The support arm 120 is mainly composed of two first joints 122, two arm parts 123, and two second joints 124 with respect to one fixed part 121.

  Among these, the fixing part 121 is a part for fixing the support arm 120 to the main body part 111 of the attracting light generating part 110, and is fixed to the back surface of the main body part 111 with a screw (not shown). Arm portions 123 are connected to both sides of the fixing portion 121 through first joints 122, respectively. The first joint 122 is a connecting member that can rotatably support the arm portion 123 with respect to the fixing portion 121 and can be fixed at an arbitrary rotational position. The first joint 122 is in a locked state where the rotational displacement of the arm portion 123 becomes impossible by tightening the screw of the operating element, and the locked state of the arm portion 123 is released by loosening the screw of the operating element. To enable rotational displacement.

  The arm portion 123 is a rod-like member for supporting the sheet holder 130 at a position away from the attraction light generation unit 110, and one end portion is the attraction light generation unit via the first joint 122 and the fixing unit 121. The sheet holding body 130 is supported by the other end portion via the second connecting member 124 while being supported by the body portion 111 of the 110. The second joint 124 is a connecting member that rotatably supports the sheet holding body 102 with respect to the arm portion 123 and can be fixed at an arbitrary rotational position. The second joint 124 is in a locked state in which the rotational displacement of the sheet holder 130 becomes impossible by tightening a screw of the operator, and the locked state of the sheet holder 130 is loosened by loosening the screw of the operator. It is released and it is in a state where it can be rotationally displaced.

  As a result, the support arm 120 can position the sheet holder 130 in an arbitrary direction and position with respect to the attracting light generation unit 110 and can also hold the sheet holder 130 in a fixed direction and position. Two support arms 120 are provided along the longitudinal direction on the back surface of the main body 111 of the attracting light generator 110 and support one sheet holding body 130 on each side of the main body 111. ing.

  The sheet holding body 130 is a plate-like member for holding the capture sheet 140 in a detachable manner, and mainly includes a back surface side regulation body 131 and a front surface side regulation body 132 that are arranged to face each other. As shown in detail in FIG. 2, the back side regulating body 131 is a resin plate-like member disposed on the back side of the capture sheet 140, and is formed to extend along the longitudinal direction of the attracting light generating unit 110. ing. The back surface side regulation body 131 is formed to be recessed in a concave shape with respect to the front surface side regulation body 132. In this case, the dent amount of the back side regulating body 131 is set to an amount that can secure a bending allowance that allows the capture sheet 140 accommodated in a bent state to be further bent and deformed toward the back side regulating body 131. In the present embodiment, the gap S <b> 1 between the capture sheet 140 accommodated in a bent state and the back surface side regulation body 131 is set to a gap slightly thicker than the thickness of the capture sheet 140.

  The front surface side regulation body 132 is a resin-made frame-like member disposed on the front surface side of the capture sheet 140 and is formed in a rectangular shape having a size capable of holding the back side regulation body 131 and the capture sheet 140. The surface side regulating body 132 is supported by a part of the peripheral part connected to the second joint 124 of the support arm 120 so as to be rotatable, and the other part of the peripheral part via a fitting part 133. The back side regulating body 131 is connected to support the back side regulating body 132 in a detachable manner.

  Moreover, the back surface which opposes the capture sheet 140 among the front and back surfaces of the front surface side regulation body 132 is notched in a concave shape with a size and shape capable of storing the capture sheet 140 and protrudes toward the back surface regulation body 131 side. A protrusion 132a is formed. This protrusion 132a is a part for pressing the capture sheet 140 disposed between the back side regulation body 131 and the front side regulation body 132 toward the back side regulation body 131 to bend the capture sheet 140 into a curved surface. And are provided on the both sides in the width direction of the notched portion on the back surface of the front-side regulating body 132 in a long manner. That is, a holding space 134 having a size and a shape in which a gap S2 that can be further curved and deformed is secured between the back side regulating body 131 and the front side regulating body 132 while being curved. ing.

  The capture sheet 140 is a flexible sheet-like member having an adhesive surface 141 for capturing pests attracted by the attracting light emitted from the attracting light generating unit 110, and the resin material is arranged in the vertical direction in the figure. It is formed in a rectangular shape that extends. The pressure-sensitive adhesive surface 141 is configured by applying a pressure-sensitive adhesive (for example, polybutene) that exerts a pressure-sensitive adhesive force for capturing pests that come into contact with one surface of the capture sheet 140. In this case, the pressure-sensitive adhesive is applied to a portion other than the edge portion and the portion facing the front surface side regulation body 132 on one surface of the capture sheet 140 (the surface facing the front surface side regulation body 132). Note that one surface of the capture sheet 120 on which the adhesive surface 141 is formed constitutes the surface of the capture sheet 140.

  In addition, the surface of the capture sheet 140 is coated with a fluorescent material (for example, a fluorescent agent such as a fluorescent dye) that emits fluorescence upon receiving the attracting light emitted from the attracting light generating unit 110. Is configured. In the present embodiment, the fluorescent screen is formed by applying the fluorescent agent to the lower layer of the adhesive surface 141 on the surface of the capture sheet 140. In this case, green, yellow, red, blue, orange, or white and an intermediate color thereof can be adopted as the color that the surface including the adhesive surface 141 of the capture sheet 140 is fluorescently colored. According to the present inventors, it has been confirmed that yellowish green as a fluorescent color improves the capture rate compared to other colors. The fluorescent screen can also be formed by applying a mixture of the adhesive and the fluorescent agent to the surface of the capture sheet 140 in addition to applying the adhesive to the surface of the capture sheet 140.

(Operation of insect trap 100)
Next, the operation of the insect trap 100 configured as described above will be described. First, a user who uses the insect trap 100 prepares two capture sheets 140 for one insect trap 100 and sets the capture sheets 140 on the two sheet holders 130 in the trap 100, respectively. Specifically, the user inserts each capture sheet 140 into a holding space 134 formed between the back side regulating body 131 and the front side regulating body 132 in each sheet holding body 130. In this case, the user inserts the adhesive surface 141 of the capture sheet 140 into the holding space 134 so as to face the surface-side regulating body 142 side. In the present embodiment, the user inserts the capture sheet 140 from above in the figure. In this case, the capture sheet 140 is not coated with the adhesive on the edge portion on the surface where the adhesive surface 141 is formed and on the portion facing the surface side regulation body 132. Therefore, the user can easily set the capture sheet 140 in the sheet holder 130 by gripping a portion of the capture sheet 140 where the adhesive is not applied. Then, the capture sheet 140 is inserted into the holding space 134 while being bent and deformed in an arc shape along the curved shape of the back-side regulating body 131 by the curved shape of the back-side regulating body 131 and the projection 132a of the front-side regulating body 132. It is.

  Next, the user installs the insect trap 100 in a place where pest control is desired. Specifically, the user installs the insect trap 100 in a direction in which the attracting light can be emitted toward the area for exterminating the pest in a place where the power can be secured in or around the area for exterminating the pest. In this case, the user can fix the main body 111 from a ceiling or a beam of an agricultural house or the like in a state where the main body 111 of the attracting light generation unit 110 is fixed to an existing columnar member or a newly provided columnar member. The insect trap 100 can be installed in a state where it is suspended. In addition, the posture when installing the insect trap 100 may be arranged so that the longitudinal direction of the attracting light generator 110 is parallel to the vertical direction, or arranged so that the longitudinal direction is parallel to the horizontal direction. Alternatively, it may be arranged such that the longitudinal direction is inclined with respect to the vertical direction and the horizontal direction, respectively.

  Next, the user starts using the insect trap 100. Specifically, the user adjusts the orientation and position of the capture sheet 140 by operating the sheet holder 130 after turning on the power switch 112 of the insect trap 100 and irradiating attracting light from the light emitter 113. . In this case, the user releases the locked states of the arm unit 123 and the sheet holding body 130 by rotating the operation elements of the first joint 122 and the second joint 124 in the support arm 120. As a result, the support arm 120 of the insect trap 100 is in a state in which the orientation and position of the arm portion 123 and the sheet holder 130 can be freely changed. Therefore, the user can position the direction and position of the capture sheet 140 in arbitrary directions and positions by changing the direction and position of the sheet holder 130 by operating the sheet holder 130.

  When the user positions the capture sheet 140 in an arbitrary direction and position, the user rotates the operation members of the first joint 122 and the second joint 124 to rotate the arm portion 123 and the seat. The orientation and position of the capture sheet 140 can be fixed by bringing the holding bodies 130 into the locked state again. Thereby, the user can start the attraction and capture of the pest by the insect trap 100 in a state in which the direction and position of the capture sheet 140 in the insect trap 100 are directed to the region to be exterminated.

  A part of the attracting light emitted from the light emitter 113 of the attracting light generation unit 110 is directly irradiated toward the pest control region, and the other part is the capture sheet 140 held by the sheet holder 130. , And a part of the light is absorbed by the capture sheet 140 to emit fluorescence and the other part is reflected. Therefore, the insect trap 100 radiates the attracting light directly from the attracting light generation unit 110 and irradiates the attracting light composed of the fluorescence and the reflected light from the capturing sheet 140 toward the areas for exterminating the pests.

  Thereby, the insect pest is attracted to the insect trap 100 from the region irradiated with the attracting light. That is, in the insect trap 100 according to the present invention, since the capture sheet 140 is arranged around a part of the attracting light generating unit 110, it is possible to attract the pests in the region irradiated with the attracting light, It is possible to prevent attracting pests from a region where the attracting light is blocked and not irradiated, in other words, a region where pest attracting is not desired. Moreover, since the insect trap 100 is provided with the two capture sheets 140 via the two sheet holders 130 on both sides of the attracting light generating unit 110, each capture sheet 140 is directed toward the area for exterminating the pests. Can attract and capture pests.

  A part of the pest attracted to the insect trap 100 comes into contact with the adhesive surface 141 of the capture sheet 140 and is captured. In this case, the capture sheet 140 is held in the holding space 134 in a state where it can be displaced / or elastically deformed in the thickness direction of the capture sheet 140. For this reason, the capture sheet 140 is displaced and / or deformed in the thickness direction by contact with the pests, more specifically, on the back side regulation body 131 side, and moves in the direction in which the pests are separated from the capture sheet 140. As a result, it is displaced and / or deformed toward the surface side regulating body 132 side. That is, since the capture sheet 140 is held in the holding space 134 with a tracking margin that follows the movement of the pests in at least the range of the gap S1 between the capture sheet 140 and the back side regulating body 132 in the bent state. Pests once attached to the adhesive surface 141 are difficult to separate. Thereby, the capture sheet 130 can capture pests with high accuracy.

The capture of the pests by the capture sheet 140 is actively performed while the light emitter 113 of the attracting light generating unit 110 is lit. During the extermination of pests by the insect trap 100, since the adhesive is not applied to the portion of the capture sheet 140 that faces the surface-side regulating body 132, the sticking of the capture sheet 140 to the surface-side regulating body 132 is prevented. can do. Thereby, the insect trap 100 can maintain the said displacement and the said deformable state of the capture sheet | seat 140 during extermination of a pest favorably, and can prevent the fall of the capture precision of a pest over a long period of time. it can.

  On the other hand, when ending pest control by the insect trap 100, the user can end the pest control work by the insect trap 100 by turning off the power switch 112. In this case, the user can fold the two sheet holders 130 so that the capture sheets 140 face each other by releasing the locked state of the first joint 122 and the second joint 124 of the support arm 120. . Thereby, the insect trap 100 can prevent foreign matters such as insects, dust, water, and dust from adhering to the capture sheet 140 in a resting state in which no attracting light is irradiated from the attracting light generating unit 110.

  In addition, when the capture sheet 140 reaches the pest capture capacity, or when the adhesive force of the adhesive surface 141 of the capture sheet 140 decreases, the user performs a replacement operation of the capture sheet 140. Specifically, the user pulls out the capture sheet 140 from the holding space 134 formed between the back side regulating body 131 and the front side regulating body 132. Even in this case, the user can easily pull out the capture sheet 140 from the sheet holding body 130 by gripping a portion of the capture sheet 140 to which the adhesive is not applied. Next, after preparing a new capture sheet 140, the user can replace the capture sheet 140 by inserting the new capture sheet 140 into the holding space 134 in the same manner as described above.

  As can be understood from the above description of the operation, according to the above embodiment, the insect trap 100 is an attractant that emits an attracting light that attracts the insect by the sheet holder 130 that holds the capture sheet 140 that captures the insect by the adhesive surface 141. The direction and / or position of the light generator 110 can be changed. As a result, the insect trap 100 changes the orientation and position of the capture sheet 140 according to the environment (for example, illuminance, temperature, humidity, weather, season, etc.) to control the pest and the type and size of the pest to be controlled. can do. Thereby, the insect trap 100 can improve the attracting ability and capturing ability of pests.

  Furthermore, in carrying out the present invention, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the object of the present invention. In the following modifications, the same reference numerals are given to the same components as those in the above embodiment, and the description thereof is omitted.

  For example, in the above-described embodiment, the sheet holding body 130 that holds the capture sheet 140 is supported by the support arm 120 so that the orientation and position thereof can be changed. Specifically, the position of the sheet holder 130 can be mainly changed by the first joint 122 in the support arm 120 and the direction can be changed by the second joint 124. However, the insect trap 100 only needs to be configured so that at least one of the orientation and position of the sheet holder 130 can be changed with respect to the pest control region. Therefore, for example, the insect trap 100 can be configured to change only the position of the sheet holder 130 by configuring the support arm 120 by omitting the second joint 124, and the support arm 120 can be configured as the first support arm 120. By omitting the joint 122, only the orientation of the sheet holder 130 can be changed.

  Further, in the above embodiment, the capture sheet 140 is configured such that the adhesive surface 141 emits fluorescence by attracting light by applying a fluorescent material to the adhesive surface 141. Thereby, the insect trap 100 can attract the pests that live in the extermination target area directly toward the adhesive surface 141. However, the insect trap 100 according to the present invention does not necessarily require a fluorescent screen as long as the capture sheet 140 includes at least the adhesive surface 141.

  In the above embodiment, the sheet holder 130 forms a holding space 134 having a gap S1 that can displace and deform the capture sheet 140 elastically deformed into a curved shape in the thickness direction of the capture sheet 140. Configured. That is, the sheet holding body 130 is configured by forming the back side regulating body 131 into a curved concave shape and cutting out the back side of the front side regulating body 132 to provide a projection 132a. However, the form which hold | maintains the capture sheet 140 in the thickness direction so that a displacement and / or deformation | transformation is possible is not limited to the said embodiment. For example, as shown in FIG. 3, the sheet holding body 130 is formed with a back-side regulation body 131 and a front-side regulation body 132 on a flat plate or a curved surface parallel to each other, and the back-side regulation body 131 and the back-side regulation body 131. You may make it arrange | position the surface side regulation body 132 through the clearance gap S2 which the capture sheet 140 can displace and / or deform | transform. In this case, the gap S2 between the back side regulating body 131 and the front side regulating body 132 is preferably 1.3 times or more, more preferably around 2 times the thickness of the capture sheet 140. Also by this, it is possible to expect the same effect as the above embodiment.

  Moreover, in the said embodiment, the sheet | seat holding body 130 hold | maintained the capture sheet 140 in the state which can be displaced and deform | transformed in the thickness direction. However, in the insect trap 100 according to the present invention, it is not always necessary for the sheet holder 130 to hold the capture sheet 140 in a state where it can be displaced and deformed in the thickness direction. In other words, the insect trap 100 according to the present invention can be implemented even if the sheet holding body 130 restricts displacement and deformation of the capture sheet 140 in the thickness direction and holds it fixedly.

  Moreover, in the said embodiment, the sheet | seat holding body 130 hold | maintained the capture sheet 140 in the state elastically deformed by the curved surface shape. However, the insect trap 100 according to the present invention does not necessarily need to be held by the sheet holder 130 in a state where the catch sheet 140 is elastically deformed into a curved shape. That is, the insect trap 100 according to the present invention can be implemented even if the sheet holder 130 is configured to hold the capture sheet 140 in a flat plate shape (see FIG. 3).

  Moreover, in the said embodiment, the insect trap 100 was equipped with the sheet | seat holding body 130 on the both sides of the attracting light generation part 110, and was comprised. However, the position and number of the sheet holders 130 included in the insect trap 100 are not necessarily limited to the above-described embodiment, and may be configured to include three or more or one sheet holder 130. For example, the insect trap 100 includes the sheet holders 130 on both ends in the longitudinal direction (both ends in the vertical direction in the drawing) of the attracting light generator 110 instead of or in addition to the sheet holder 130 in the above embodiment. In addition, it is also possible to configure only one of the two sheet holders 130 in the above embodiment.

  In the above-described embodiment, the support arm 120 is configured by one arm portion 123 and two joint portions, ie, the first joint 122 and the second joint 124 with respect to one fixing portion 121. However, the support arm 120 is not necessarily limited to the above-described embodiment as long as the support arm 120 is configured to change the orientation and / or position of the sheet holder 130. For example, the support arm 120 may be configured to include two or more arm portions 123 and one or three or more joint portions with respect to one fixing portion 121. Further, for example, the support arm 120 may be configured by a so-called flexible arm in which a long arm member that supports the sheet holding body 130 can be bent at an arbitrary position. Further, in these cases, the support arm 120 does not necessarily need to be fixed to the attracting light generating unit 110, and is supported by a member different from the attracting light generating unit 110 or autonomously supports the sheet holder 130. It can also be configured to.

  In the above embodiment, the insect trap 100 uses an external power source of 100 V as the power source of the attracting light generator 110. However, the power source of the attracting light generating unit 110 may use other types, for example, a solar battery, a rechargeable storage battery, or a dry battery.

  Moreover, in the said embodiment, the insect trap 100 was comprised so that the attracting light generation part 110 might emit the attracting light of the wavelength of an ultraviolet region. However, the attracting light generation unit 110 is not necessarily limited to the above-described embodiment as long as it is configured so as to attract pests. For example, the attracting light generator 110 can be configured by a device that emits light having a wavelength in the ultraviolet region other than the wavelength in the above embodiment and light having a wavelength other than the ultraviolet region.

  Moreover, in the said embodiment, the capture sheet | seat 140 does not form the adhesive surface 141 in these parts by not apply | coating an adhesive to the edge part in the surface and the part facing the surface side regulation body 132, respectively. The configuration. However, the insect trap 100 according to the present invention can also form the adhesive surface 141 by applying an adhesive to the entire surface of the capture sheet 140. Moreover, the insect trap 100 replaces the surface of the capture sheet 140 by, for example, configuring the back side regulation body 131 with a frame-shaped, lattice-shaped, or net-shaped opening that exposes the capture sheet 140. Alternatively or additionally, an adhesive surface 141 can be formed on the back surface to attract and capture pests.
