Description

  The present invention relates to a mousetrap used by being placed on a mounting surface such as a floor surface or the ground in a workplace such as an office, a factory, a warehouse, or a general household.

  Conventionally, various capture methods and traps for capturing mice have been proposed and practiced.

  For example, the method of killing mice by poisoning them such as poisoned dumplings has been practiced for a long time.

  Further, as a catcher, it is generally known that a bait is put in a relatively small box made of a wire mesh and a mouse enters from the entrance and tries to take this bait, so that the entrance is blocked and cannot escape.

  Furthermore, in Patent Document 1, a housing whose front side is opened is constituted by a bottom plate, left and right side plates, an upper plate, and a back plate, and a vertically movable door is set in an open state in this opening, and the mouse is a housing. A device is disclosed in which the device is removed and the door is closed when it enters the inside.

JP 2005-328716 A

  However, the method of eating a poisonous mouse does not know where the poisonous mouse will die.For example, if the mouse is dead on the ceiling, a bad smell or miscellaneous bacteria may be generated due to postmortem decay. There is a problem that it is not hygienic. There is also a safety problem that if a pet accidentally eats a poison, it will die.

  In addition, although the trap made of wire mesh is simple and convenient, other mice can easily see the captured mice from the outside, so they can learn and capture them. There is a problem that the container becomes difficult to hang.

  Furthermore, although the mouse | mouth captured by the housing of patent document 1 becomes invisible from the exterior, after that, the mouse | mouth captured in the housing | casing must be taken out with a hand or an instrument, and this operation | work is complicated. There was a problem of being.

  The above problem also applies to the case of capturing small animals other than mice.

  Therefore, the present invention is hygienic and safe, prevents the captured mouse (small animal) from being seen from the outside, allows the mouse (small animal) to be well captured, and further, the mouse after capture (small animal). An object of the present invention is to provide a mouse removal that can be easily post-processed.

  The invention according to claim 1 relates to a mousetrap used by being placed on a mounting surface. The mousetrap according to the present invention includes a guideway having an entrance provided at an end and opening laterally, and a bait holder provided at a depth from the entrance, and the entrance A door which is attached and is movable between an open position for opening the entrance and a closed position for closing the entrance; a detecting means for detecting that a mouse has entered from the entrance; and Closing means for releasing the locking by the detection signal of the detection means and moving the locked door to the closed position; and a base end portion is branched laterally from the guide path and a distal end portion is closed A removable capture path, a light source provided at the front end of the capture path to allow for daylighting from outside and prohibiting internal viewing from the outside, and a mouse entering the capture path.

  According to a seventh aspect of the present invention, in the mousetrap according to the sixth aspect, the detecting means detects a footboard that is disposed near the bait holder and descends when the mouse rides, and detects the lowering of the footboard. And a switch for operating the electromagnet.

  According to an eighth aspect of the present invention, in the mousetrap according to any one of the first to seventh aspects, the door extends toward the back side on the inner surface located on the inner side when the door is disposed at the closed position. It has a shape member.

  The invention according to claim 9 is the mousetrap according to any one of claims 1 to 8, wherein the biasing member biases the door toward the closed position between the door and the guide path. Is interposed.

  The invention according to claim 10 is the mousetrap according to any one of claims 1 to 9, wherein the guide path has the entrance at one end and the other end, and the door is It is attached to each of the entrances of the one end and the other end.

  According to an eleventh aspect of the present invention, in the mousetrap according to the tenth aspect, the guide path is a slit in which a transparent plate for closing the entrance is inserted and removed at the one end and the other end. It is characterized by having.

  According to the first aspect of the present invention, when the mouse enters from the entrance of the guide path, the detection means detects this, and the entrance is closed by the closing means. The mouse, whose retreat path is closed, proceeds toward the light at the front end of the capture path and enters the capture path from the taxiway. The mouse that has entered the capture path cannot be returned to the guide path by the retrograde prevention means, and is thus captured by the capture path. Although the light can be taken, the inside cannot be seen from the outside through this, so other mice cannot see the mouse captured in the catching path from the outside. This prevents other mice from learning and becoming less likely to be captured by this mousetrap. In addition, since the capture path is detachable, the mouse can be easily discharged to the outside simply by removing the capture path from the taxiway and tilting the base end (side near the taxiway) downward. it can.

  According to the invention of claim 2, since the capture path is formed in a pipe shape with a circular cross section, it can be easily engaged and disengaged while rotating with respect to the guide path.

  According to the invention of claim 3, the mouse that has entered the capture path cannot be moved freely because the adhesive sheet is adhered to the body and is captured by the capture path. Moreover, when taking out a mouse | mouth from a capture path, it can take out the whole adhesive sheet.

  According to the fourth aspect of the present invention, the mouse that has entered the capture path cannot reverse from the capture path to the guide path by the retrograde prevention member.

  According to the invention of claim 5, since the tip of the guide path is detachable, for example, even when a member for preventing retrograde is provided on the catching path side, the mouse is removed from here by removing the tip. It can be discharged to the outside.

  According to the invention of claim 6, the door can be moved from the open position to the closed position by moving the closing member from the engagement position to the release position with the electromagnet.

  According to the seventh aspect of the present invention, the switch can detect when the mouse descends on the tread board and issues a detection signal to activate the electromagnet to close the door.

  According to the invention of claim 8, when the door is closed, when a part or tail of the mouse is not completely entered from the entrance, or when the mouse tries to escape from the entrance, Since the member stabs the mouse and gives a stimulus, the mouse is surprised and moves to the back side.

  According to the ninth aspect of the present invention, since the biasing member that biases the door in the closing direction is interposed between the door and the guide path, the door can be closed smoothly and reliably when the door is closed. it can.

  According to the tenth aspect of the present invention, since the entrance and the door for closing the entrance are provided at both ends of the guide path, it is easy to see the bait placed on the guide path. The mouse is allowed to enter. Furthermore, from another point of view, the taxiway can be seen as a passage having an entrance and an exit, so that the mouse easily enters from this point.

  According to the eleventh aspect of the present invention, for example, in the case where one entrance is preferable to two due to restrictions such as the place where the mousetrap is placed, a transparent plate is inserted into the slit to provide one entrance. Close and place the door in the open position. As a result, the transparent plate acts as a light collector, and the mouse makes it easy to see the food in the taxiway. When a mouse enters the taxiway, the doors of both entrances are closed, but one of them is the original purpose, which blocks the entrance and cuts the exit of the mouse, while the other is transparent. The door on the plate side is already a transparent plate and the mouse's retraction is cut off. This makes the interior invisible from the outside and makes it easier for the mouse in the taxiway to move toward the light source, which is the only light.

  With reference to FIGS. 1-4, the mousetrap 1 of Embodiment 1 to which this invention is applied is demonstrated. Here, FIG. 1 is a partially broken perspective view showing the entire structure of the mousetrap 1. In the following, for the sake of convenience of explanation, the front, rear, left, right, top, and bottom indicated by arrows at the top in FIG. 1 are described as front, back, left, right, top and bottom of the mousetrap 1, but the front and rear direction and the left and right direction may be interchanged. Of course. FIG. 2 is a diagram for explaining the detection means 30. FIG. 3 is a diagram illustrating the capture path 50. FIG. 4 is a schematic diagram illustrating the operation of the mouse in the mousetrap 1 as seen from above. In FIG. 4, hatching is omitted.

  As shown in FIG. 1, the mousetrap 1 includes entrances 11 and 11, a guide path 10 having a bait holder 12, openable doors 20 and 20 attached to the entrances 11 and 11, and an entrance, respectively. 11 and 11, a detecting means 30 for detecting that a mouse (not shown) has entered, a closing means 40 for closing the door 20 by a detection signal of the detecting means 30, and a lateral direction (forward direction) from the guide path 10. The branched capture path 50, the light collecting 60 provided at the front end (front end) 50 a of the capture path 50, and the anti-reverse means 70 for preventing the mouse entering the capture path 50 from going back to the guide path 10. And.

  The guide path 10 is formed in a square cylinder shape, and includes a bottom plate 13, a top plate 14, and a pair of front and rear side plates 15, 15. The bottom plate 13 is placed on a mounting surface such as a floor surface or the ground. The guide path 10 has openings at both ends in the longitudinal direction (left-right direction), and these openings serve as entrances 11 through which the mouse enters. A bait holder 12 is provided in the depth direction from the entrances 11, 11, that is, in the longitudinal center of the upper surface of the bottom plate 13, and a pin 16 to which the bait F is attached projects. It is installed. A tread plate 31 (a part of the detection means 30) is disposed on both the left and right sides so as to sandwich the pin 16. Further, a mounting hole 13a (see FIG. 2) for mounting the switch sensor 32 (a part of the detecting means 30) is vertically penetrated in a portion of the bottom plate 13 positioned below the tread plate 31. In addition, the guide path 10 has a substantially central portion in the longitudinal direction of one side plate (front side plate) 15 that is pierced in a circular shape. Here, a cylindrical shape for attaching the capture path 50 to the outside is provided. The pedestal 17 is provided. Further, in the vicinity of each entrance 11 in the front side plate 15, a slit 15 a extending in the vertical direction is provided so as to penetrate the front side plate 15 in the front-rear direction. A transparent plate 18 (for example, an acrylic plate or a vinyl chloride plate) that closes the entrance 11 is detachably inserted into the slits 15a. The operation of the transparent plate 18 will be described later.

  The doors 20 and 20 are attached to the respective entrances 11 and 11 at both ends in the longitudinal direction of the guide path 10. Each door 20 is formed in a rectangular shape slightly larger than the entrance 11, and two (plural) hinges 21 are attached between the upper end 20a and the end of the top plate 14 of the guide path 10. With these hinges 21 as the swing center, between the open position P1 (see the solid line in FIG. 1) for opening the entrance 11 and the closed position P2 (see the two-dot chain line on the right door in FIG. 1) for closing. Can be moved (oscillated). One of the two hinges 21 and 21 is a spring member 21a that urges the door 20 in the direction of arrow R1 (the closing direction) toward the closing position P2 (see the two-dot chain line of the right door 20 in FIG. 1). Thus, when the door 20 is closed, the door 20 is reliably and quickly closed by its own weight and urging force, and is difficult to open after being placed at the closed position P2. An “L” -shaped hook 22 projects from the approximate center of the outer surface 20 b of the door 20. Further, a plurality (a large number) of needle-like members 23, 23,... Project from the inner surface 20c of the door 20 so as to face the back side when the door 20 is disposed at the closed position P2. 1, illustration of the needle-like members 23, 23... Of the right door 20 is omitted. These needle-like members 23, 23... Are for preventing a mouse once trapped in the guide path 10 from pushing the door 20 outward to open it. The needle-like members 23, 23... Are detachably fitted to the fitting holes (not shown) formed in the door 20 at the base end side.

  As shown in FIG. 2, the detection means 30 includes two tread plates 31 and 31, sensor switches (switches) 32 and 32, and spring members (compression springs) 33 and 33. Each tread plate 31 is formed of a rectangular thin plate, the proximal end side is stopped by a tape 34, and the distal end side is biased upward by a spring member 33 to maintain an inclined posture. In the sensor switch 32, the sensor body 32 a is fitted in the mounting hole 13 a of the bottom plate 13 of the guide path 10, and the switch portion 32 b that can move up and down with respect to the sensor body 32 a contacts the back surface (lower surface) of the tread plate 31. Or it is arranged through a slight gap. When the tread 31 is stepped on and lowered by the mouse, the detection means 30 is turned on by pressing the switch portion 32b and outputs a detection signal. This detection signal is transmitted to the closing means 40 described below.

  As shown in FIG. 1, the closing means 40 is disposed on the top surface of the top plate 14 of the guide path 10, and includes an electromagnet 41 disposed substantially rearward of the center of the top plate 14 in the longitudinal direction, It has an arm (closing member) 42 formed in a plate shape that is long in the direction, and a spring member (tensile spring) 43 that biases the arm 42. The electromagnet 41 has a main body 44 that is fixedly arranged and an operating part 45 that is supported by the main body 44 so as to be movable in the front-rear direction. The operating part 45 is detected by a detection signal from the detecting means 30. Is pulled backward (in the direction of arrow K1) by the magnetic force of. The arm 42 is fixed at the center in the longitudinal direction to the operating portion 45 of the electromagnet 41 and can move between the engagement position P3 (see the solid line) and the release position P4 (see the two-dot chain line). The arm 42 is provided with a roller 42b that rolls on the top surface of the top plate 14 in the vicinity of both end portions. The rollers 42b and 42b maintain balance and enable smooth movement. Yes.

  The central portion of the electromagnet 41 and the arm 42 in the longitudinal direction (left-right direction) is covered with a cover member 46 that is long in the left-right direction. In the vicinity of both end portions in the longitudinal direction of the cover member 46, one end portion (base end portion) 43a of the spring member 43 is attached, and the other end portion (tip end portion) 43b of the spring member 43 is It is attached to the arm 42. With the arm 42 biased forward, the hooks 22 of the doors 20 and 20 are locked (engaged) with the respective end portions 42a and 42a in the longitudinal direction.

  When the electromagnet 41 is turned on by the detection signal of the detection means 30 and the operating part 45 is pulled backward (in the direction of the arrow K1), the closing means 40 has the arm 42 integrated with the operating part 45 attached to the spring members 43, 43. It moves from the engagement position P3 to the release position P4 against the force, thereby releasing the hooks 22 and 22 from being engaged. Thereby, the doors 20 and 20 move from the open position P1 to the closed position P2 by their own weight and the biasing force of the spring member 21a of the hinge 21, and close the entrance 11.

  The capture path 50 is branched from the guide path 10 at right angles in the lateral direction (forward), and has a pipe-shaped capture path main body 51 having a circular cross section, and a cap 52 attached to the tip 51a of the capture path main body 51. have. The capture path main body 51 is formed of, for example, an opaque vinyl chloride pipe, and the base end 51b is fitted to the inner surface of the base 17 on the guide path 10 side. This fitting state is a tight fit, and the base end part 51b (hereinafter referred to as the base end part 50b of the capture path 50 as appropriate) is pushed into the inner surface of the base 17 while rotating the capture path main body 51. It can be fitted, and when removed, the fitting can be released by pulling out while rotating. Thus, the capture path main body 51 is easy to attach and detach depending on the user's active attaching and detaching operation, but once fitted, that is, in a state where the mousetrap 1 is set in a predetermined place, It cannot be easily removed. This fitting state is the same for the cap 52. The cap 52 includes a cylindrical cylindrical portion 52a and a disc-shaped disc portion 52b. The cylindrical portion 52a is connected to the distal end portion 51a of the capture path main body 51 and the proximal end portion 51b of the capture path main body 51. Similar to the fitted state, that is, it can be attached / detached relatively easily by a positive attaching / detaching operation while rotating, for example, in a fitted state that does not fall off even when a mouse collides. Are combined. The disk portion 52b is provided with a light harvester 60.

  The light collecting 60 is constituted by a large number of through holes 61 passing through the disc part 52b in the front-rear direction. These through holes 61 can be daylighted by reducing their diameters, but it is difficult to see the inside from the outside. This light harvesting 60 enables air circulation in addition to light lighting. It is conceivable that the mouse trapped in the guide path 10 feels this air flow and moves from the guide path 10 to the capture path 50.

  As shown in FIGS. 1 and 3, the retrograde prevention means 70 is configured by an adhesive sheet 71 disposed on the inner surface of the catching path main body 51 of the catching path 50. The pressure-sensitive adhesive sheet 71 has a surface 71 a coated with a pressure-sensitive adhesive. With the surface (coating surface) 71 a wound inside, the cap 52 of the capture path 50 is removed and inserted into the capture path main body 51. Has been. The inserted pressure-sensitive adhesive sheet 71 is stored such that the back surface 71b to which the pressure-sensitive adhesive is not applied is in close contact with the inner surface of the catching path main body 51 by its own restoring force. The mouse that enters the capture path 50 from the guide path 10 sticks to the adhesive sheet 71 and cannot move. The adhesive sheet 71 has a back surface 71b that does not have an adhesive, and moderate slip occurs between the inner surface of the capture path main body 51. Therefore, in order to discharge the rat stuck to the adhesive sheet 71, the capture path main body 51 is guided. By pulling out the base 17 from the pedestal 17 of the path 10 and inclining the capture path 50 with the pulled out base end 51b downward, it is possible to discharge the mouse together with the adhesive sheet 71.

  The effect of the mousetrap 1 having the above-described configuration will be described.

  First, a case will be described in which a mouse can enter from both of the two entrances 11 and 11 of the guide path 10.

  As shown in FIGS. 1 and 4, the food F is set on the pin 16 of the food holder 12 of the guide path 10. Moreover, the cap 52 of the capture path 50 is removed, and the adhesive sheet 71 is rolled and inserted inside the capture path body 51, and the base end portion 51 b of the capture path body 51 is fitted to the base 17 of the guide path 10. Then, the doors 20 and 20 (not shown in FIG. 4) are opened and arranged at the open position P1, and the hooks 22 and 22 of the doors 20 and 20 are respectively connected to the end portions 42a and 42a of the arm 42 at the engagement position P3. Lock to. Thereby, the doors 20 and 20 can be hold | maintained in the open position P1.

  By the way, it is known that the mouse is nocturnal and, when moving, for example, does not cross the floor, but moves along the corner where the floor and the wall intersect. .

  Therefore, the mousetrap 1 is set so that the longitudinal direction of the guide path 10 is along the corner. Thereby, the guide path 10 can be arrange | positioned along a mouse | mouth channel | path. Further, the guide path 10 is formed in a square cylinder shape. For example, unlike the case where the guide path 10 is formed in a cylindrical shape, there is no gap between the corner and the guide path 10, so that the mouse is in the guide path 10. You can make it easier to enter. When the mousetrap 1 is set in the corner, the sensor switches 32 and 32 and the electromagnet 41 are connected to a power source (not shown). Preparation is now complete.

  The mouse that has traveled along the corner is attracted by the bait F attached to the pin 16 at the center of the guideway 10 and enters, for example, the left entrance 11 and proceeds in the direction of the arrow N1. When the mouse steps on the tread board 31, the tread board 31 descends, and the sensor switch 32 is turned on to generate a detection signal. By this detection signal, the electromagnet 41 is actuated, the actuating part 45 is pulled backward (in the direction of the arrow K1), and the arm 42 integrated with the actuating part 45 moves from the engagement position P3 to the release position P4. As a result, the hooks 22, 22 locked to the respective end portions 42 a, 42 a of the arm 42 are unlocked, and the doors 20, 20 arranged at the open position P <b> 1 have their own weight and hinge 21. Due to the urging force of the spring member 21a, it moves to the closing position P2 and closes the entrances 11 and 11. At this time, needle-like members 23, 23... Are attached to the doors 20, 20, and if the mouse tries to escape from the entrance 11, or if it is caught between the doors 20, 20, the needle-like members 23, 23. 23... Stabs the mouse and gives a stimulus, so the mouse cannot push the doors 20 and 20 outward to escape, but proceeds to the back side. At this time, the two doors 20 and 20 are closed, and the inside of the guide path 10 is dark. Here, the mouse moves from the guide path 10 to the capture path 50 so as to be invited to the flow of light and air leaking from the light collecting 60. The mouse that has moved to the catching path 50 sticks to the pressure-sensitive adhesive sheet 71 and cannot be moved and is captured. The same applies to the mouse that enters from the right entrance 11 and proceeds in the direction of the arrow N2.

  The captured mouse is pulled out of the base end 50b of the capture path 50 from the pedestal 17 on the guide path 10 side by the user, and then the base end 50b side is inclined downward so that the mouse is taken together with the adhesive sheet 71. Can be discharged outside. The mouse can be discharged in the same manner from the distal end 51a side of the catching path main body 51 by removing the cap 52.

  It can be said that the mousetrap 1 described above realizes a three-dimensional pitfall two-dimensionally. In the pitfalls, once a small animal falls into the pit, it cannot crawl up from the bottom of the pit and escape. On the other hand, the mousetrap 1 that has entered the taxiway 10 is invited by the light, and once enters the captureway 50, it cannot go backwards and escape. Although it is the same in this point, in this embodiment, the processing of the mouse | mouth after a capture is very easy and it differs greatly from a pitfall.

  The mousetrap 1 described above can achieve the following effects.

  The mouse that has entered the guideway 10 from the entrance 11 is detected by the detection means 30, and the doors 20 and 20 are moved to the closed position P2 by the closing means 40 to reliably close the entrances 11 and 11. Can be confined in the guide path 10. At this time, since the needle-like members 23, 23... Project from the inner side of the doors 20, 20 that close the entrances 11, 11 toward the back side, the mice pierce the needles. It cannot be released by pushing 20 outward. Further, this makes it possible to reduce the biasing force of the spring member 21a that biases the doors 20 and 20 in the closing direction. For this reason, the engagement force between the hook 22 and the arm 42 can be reduced to facilitate the movement of the arm 42. Therefore, when the arm 42 is moved from the engagement position P3 to the release position P4, it is ensured with a small force accordingly. It is possible to move to.

  When the entrance 11 is closed by the door 20, the inside of the mousetrap 1 becomes dark, and only light enters from the light 60 at the tip 50 a of the catching path 50, so the mouse trapped in the guideway 10. Moves in the direction of light and enters the capture path 50 from the guide path 10. Thus, the mouse that has entered the capture path 50 is stuck to the adhesive sheet 71 as the retrograde prevention means 70 and cannot be moved and is captured.

  In addition, when the entrances 11 and 11 are closed by the door 20, the inside of the mousetrap 1 cannot be seen from the outside, so that other mice outside are trapped in the taxiway 10. I ca n’t see what ’s being caught in the capture path 50. For this reason, it is not possible to learn, and there is no possibility that other mice will not easily catch the mousetrap 1.

  The trapped mouse can be discharged together with the adhesive sheet 71 by removing the capture path 50 from the guide path 10 and inclining the base end 50b side downward. It is also possible to remove the cap 52 and discharge the same to the outside. In any case, since the user does not have any work of touching the mouse or picking out the mouse with a tool such as a pinch, the mouse can be treated hygienically and very easily.

  In addition, at the time of processing of the captured mouse, the guide path 10 side where the electrical components such as the sensor switches 32 and 32 and the electromagnet 41 that need to be connected to the power source via the lead wire are moved is moved at all. It is not necessary to perform this process, and only the capture path 50 that is detachably attached to the guide path 10 side can be processed. Therefore, it is possible to simplify the process from this point.

  Next, the case where only one entrance 11 (left entrance 11 in FIG. 1) of the guide path 10 is used will be described. Depending on the location of the mousetrap 1 or the like, there is a case where only one (left) entrance 11 is sufficient or only the left entrance 11 can be used. In such a case, the right entrance 11 is closed by inserting the transparent plate 18 into the slit 15a, and the right door 20 is disposed at the open position P1. The right door 20 is removed because the needle-like members 23, 23... Are unnecessary. Thus, the reason why the right door 20 is not closed is to brighten the inside of the guideway 10 so that the food F can be easily seen, and the food can also be seen from the closed right entrance 11. . When the mouse enters from the left entrance 11 and the detection means 30 detects this, and the closing means 40 is activated, both doors 20 and 20 are placed in the closed position P2. In addition, since it is the same as that of the case where both the entrances 11 are open | released after that, description is abbreviate | omitted.

  Next, modifications of each component will be described.

  In the above description, the case where the guide path 10 has a rectangular cylindrical shape has been described as an example. However, the shape of the guide path 10 is not limited to a square cylindrical shape, and for example, a hexagonal cylindrical shape or a cylindrical shape may be adopted. Is also possible. However, considering that the general installation location of the mousetrap 1 is the path of the mouse, that is, the corner where the mounting surface such as the floor or the ground intersects the wall perpendicular to it, it fits perfectly in this corner. A full rectangular tube shape is preferred.

  With reference to FIG. 5, the modification of the detection means 30 is demonstrated. The figure is a schematic view of the inside of the taxiway 10 as viewed from above. As the detection means 30, it is also possible to use a light transmission type optical sensor 35 as shown in FIG. 5 instead of using the above-described footboard 31 and sensor switch 32. The light projecting portion 35 a is provided on one side plate 15 of the guide path 10, and the light receiving portion 35 b is provided on the other side plate 15. The optical sensor 35 can generate the detection signal and operate the closing means 40 when the mouse blocks the optical path L formed between the light projecting unit 35a and the light receiving unit 35b. In addition, when using such an optical sensor 35, the tread board 31 becomes unnecessary.

  With reference to FIGS. 6, 7 and 8, different closing means 40 will be described. In FIG. 6, an arm (closing member) 47 is disposed so as to be swingable with respect to a swing center 47a set in the vertical direction. In addition, the electromagnet 41 is disposed so as to be shifted from the swing center 47 a in one of the longitudinal directions, and the operating portion 45 of the electromagnet 41 is fixed to the arm 47 at this position. When the operating portion 45 of the electromagnet 41 is moved in the direction of arrow K2 by the detection signal of the detection means 30, the end portions 47b and 47b of the arm 47 are moved in the directions of arrow R2 and arrow R3, respectively, and the hooks 22 of the doors 20 and 20 are moved. , 22 is released. In this example as well, rollers 42b similar to the rollers 42b shown in FIG. 1 may be provided at the ends of the arms 47 where the electromagnet 41 is not provided.

  In FIG. 7, the arm 48 (closing member) is divided into two parts, which are a left arm 48a and a right arm 48b that can move in the longitudinal direction. In addition, the electromagnet 41 is disposed sideways, and the operating portion 45 is fixed to a mounting portion 48c projecting from the base end portion of the left arm 48a. Further, racks (not shown) are respectively formed at the base end portion of the left arm 48a and the base end portion of the right arm 48b, and a pinion 48d is interposed between these racks. When the operating portion 45 of the electromagnet 41 is moved in the direction of the arrow K3 by the detection signal of the detection means 30, the left arm 48a is moved in the direction of the arrow K4, and the right arm 48b is moved in the direction of the arrow K5. The hooks 22 and 22 that have been engaged are released. According to the example shown in FIG. 7, since the long left arm 48a and the right arm 48b are moved in the longitudinal direction, even when a relatively light arm is used, there is no need to consider the deformation of the arm, etc. The operation is reliable.

  In FIG. 8, solenoids 49 and 49 (however, only one of them is shown in FIG. 8) are disposed at both ends in the longitudinal direction of the top plate 14 of the guide path 10, and can be expanded and contracted with respect to the main body 49a. The plunger 49b is engaged with the hook 22 in the extended state. Due to the detection signal of the detection means 30, the plunger 49b is shortened in the direction of the arrow K6, and the hook 22 is unlocked. Although the solenoid shown in FIG. 8 requires two solenoids 49 and 49, a long arm is unnecessary, the configuration can be simplified, and the operation is reliable because the arm is unnecessary. It will be a thing.

  In addition, although the thing of a respectively different structure was demonstrated with reference to FIG. 1, FIG. 6-FIG. 8 about the closing means 40, in this invention, any of these can be used about the closing means 40, It is also possible to employ another closing means 40 other than these.

  With reference to FIG. 9, the modification of the capture path 50 is demonstrated. In the above description, the case where the capture path 50 is orthogonal to the guide path 10 and intersects in a “T” shape has been described. However, as illustrated in FIG. 9, the capture path 50 may be configured in a “ten” shape. . That is, a similar capturing path 50 may be provided on the left side plate 15 of the guiding path 10. In any case, the capture path 50 is not limited to being orthogonal to the guide path 10, and may be branched at an appropriate angle. For example, when only the left entrance 11 is used, as shown in FIG. 10, θ is 90 with respect to the traveling direction so that the mouse entering from the entrance 11 can easily move from the guide passage 10 to the capture passage 50. You may make it incline so that it may become a loose angle below a degree.

  With reference to FIG. 11, another example of the lighting 60 will be described. An inner through hole 62 having a diameter larger than that of the through hole 61 shown in FIG. 1 is formed in the side wall of the distal end portion 51a of the catch path main body 51 of the catch path 50. On the other hand, an outer through hole 63 having the same size is formed in a radial direction at a position corresponding to the inner through hole 62 in the cylindrical portion 52 a of the cap 52. If comprised in this way, opening area S, ie, substantially light, will be carried out by shifting the position of the outer side through-hole 63 by rotating the cap 52 suitably with respect to the inside through-hole 62 by the side of the capture path main body 51. FIG. It is possible to adjust the area of the portion where the is inserted. Furthermore, if the inner through-hole 62 and the outer through-hole 63 are made to coincide with each other to increase the opening area S, the user sees the appearance inside the capture path 50 from the outside without removing the capture path 50 from the guide path 10 side. be able to.

  With reference to FIG. 12, another example of the retrograde prevention means 70 will be described. The retrograde prevention means 70 is formed by a large number of elastic blades (retrograde prevention members) 72, 72. Each blade 72 has a proximal end portion 72 a fixed to the inner surface of the capture path main body 51 and a distal end portion 72 b that is free and arranged toward the distal end side and the center side of the capture path 50. When the mouse passes from the guide path 10 side toward the capture path 50 side, each vane 72 expands to allow the retrograde prevention means 70 to pass therethrough. On the other hand, when going backward from the capture path 50 side to the guide path 10 side, the tip 72b of each blade 72 moves in the direction of narrowing and prohibits passage. The retrograde prevention means 70 may be disposed inside the base 17 of the guide path 10 instead of the base end portion 51 b of the capture path main body 51. When arranged on the pedestal 17 side, the structure of the capture path 50 to be attached and detached during the treatment of the mouse can be simplified and lightened to improve workability, while on the other hand, when disposed on the capture path main body 51 side, When removing the capture path 50 from the pedestal 17, there is no risk of accidentally dropping a mouse that has already been captured from the capture path 50. As the retrograde preventing means 70, both the adhesive sheet 17 and the blades 72, 72,...

  Each blade 72 can be formed of, for example, synthetic resin or metal. Furthermore, instead of the blades 72, a large number of thin wire-like metal bars having appropriate elasticity may be attached. These metal rods are disposed in a funnel shape as a whole with the base end side fixed to the inner surface of the capture path main body 51 and the tip end side directed toward the center. For example, if the tip side is formed in a needle shape, the mouse is stabbed into the mouse that is going to go backward, so that the mouse can't go backwards forcibly, and it is possible to reliably prevent the backward movement.

  The mousetrap 1 described above is mainly called mousetrap because it is intended to catch the mouse, but the mousetrap 1 is also used to capture not only mice but also other small animals. Of course you can.
