BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for catching insects used for controlling pests.

[0002]

2. Description of the Related Art A ribbon-shaped double-sided pressure-sensitive adhesive tape is generally known as a trapping tool for exterminating pests using a pressure-sensitive adhesive sheet indoors and outdoors. Such a double-sided pressure-sensitive adhesive tape for catching insects is mainly intended for controlling flies, and the necessity for ordinary households in recent years has been reduced. However, suburban facilities and medical facilities that require a clean atmosphere,
The necessity is being reexamined in facilities that use required hygiene management of foods or the like, or facilities related to electronic devices related to semiconductor manufacturing and the like.

That is, in a so-called clean room or the like in the above-mentioned facility, in order to ensure the qualitative reliability of the product or to perform sanitary control, a multi-door, an air curtain, and other facilities effective for insect control are constantly operated. In spite of this, they escape and rarely enter by insects. As a method of controlling such insects, it is necessary to use a method that does not contaminate the clean atmosphere, and therefore, a method with a high control efficiency, such as spraying of a pesticide, cannot be adopted. And so on.

As an insect trapping device provided with an adhesive sheet, a light source that emits a light beam having a predetermined wavelength to attract insects is mounted on the front of a rectangular box-shaped machine frame. In some cases, the pressure-sensitive adhesive sheet is detachably mounted face-up on a substantially same plane as the reflection surface with a hook such as a hook or a clip.

[0005]

However, in the above-mentioned conventional insect trapping device, the sticky surface of the pressure-sensitive adhesive sheet is attached to the front of the device, so that the trapped insects and dirty light source can be removed. There is a problem that there is a sense of dirty when seen from outside the device. In addition, since the work of attaching a wide adhesive sheet on the same plane as the reflector behind the light source is complicated, the workability of renewing the adhesive sheet and the capture efficiency cannot be solved at once.

The present invention solves the above-mentioned problems, so that the captured insects and the light source are not visible from the outside, so that they are not dirty during use, and a relatively large area is used to increase the trapping efficiency. It is an object of the present invention to provide an insect catching device that can easily update an adhesive sheet even when an adhesive surface is used.

[0007]

In order to solve the above-mentioned problems, in the present invention, a single-sided adhesive sheet wound in a roll shape is provided inside a machine frame so as to be rotatable about a horizontal axis. A front cover for covering the non-adhesive surface of the pulled-out adhesive sheet on the front side inside the machine frame, and the front cover
Guide the adhesive sheet so that it hangs down
An insect trap provided with a rotating ring guide and a light source for illuminating the adhesive surface on the rear side inside the machine frame.
That is, the device was adopted.

Further, a configuration in which an optical reflecting surface is provided inside the machine frame may be adopted.

[0009]

The insect trapping device according to the present invention has a drawn-out adhesive surface of a freely rotating roll-shaped adhesive sheet inside the front of the machine frame facing the light source on the rear side of the machine frame. As a result, the adhesive surface can be renewed simply by pulling out a wide, large-area adhesive sheet .
The renewal workability and the capture efficiency can be both improved with a simple structure without the need for a roll or the like . Also,
Since the adhesive surface is guided and held rearward facing the light source on the front side inside the machine frame by the guide with the front cover , the captured insects and the light source are not visible from the front of the device, making it dirty. Can be used without.

[0010]

An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the embodiment comprises a front cover 1 connected to the front half of the top wall, a rear cover 2 connected to the rear half of the top wall, and upper and lower side walls 3 and 4 fixed to the back cover 2. A rolled adhesive sheet 6 is rotatably provided inside a machine frame 5 made of a stainless steel plate composed of an edge frame portion 1a, 2a, and 3a integrated therewith, with a shaft core disposed in the left-right direction. The roll shafts 7, 8 with rings 7a, 8a for guiding the adhesive sheet 6 are attached to the front ends of the lower side walls 3, 4, respectively, and a light source 9 by a fluorescent lamp is arranged inside the back cover 2.

As shown in FIG. 2, the front cover 1 of the machine casing 5
Is formed with a slit 10 that opens downward on the outer surface, so that the light from the light source 9 passes through the adhesive sheet 6 and leaks to the outside to enhance the effect of attracting insects. Front cover 1
A plate-like projection 11 is provided downward at the upper end of the rear cover 2, and when engaged with a locking hole 12 formed at the upper end edge of the back cover 2,
The front cover 1 can be temporarily fixed in a half-open state. Further, as shown in FIG. 1, when the hook 13 fixed to the edge frame 1a and the hook of the clamp 14 with the toggle mechanism attached to the lower side wall 4 are engaged, the front cover 1 and the rear cover 2 are completely completed. Fixed.

In addition, a locking hole 15 which can be locked to an existing nail or hook is formed at a key point of the rear cover 2 so that the rear cover 2 can be attached to a wall surface or the like.

The pressure-sensitive adhesive sheet 6 is formed by applying a known pressure-sensitive adhesive to the other surface of a paper sheet having a releasable surface. The pressure-sensitive adhesive sheet 6 is formed on a cylindrical core 16 made of cardboard or the like. of the length of the web, toward the adhesive surface 6a to the inside
It is wound in the form of a roll in the state. A bearing 18 with a flange is detachably fitted in a through hole 17 formed at a position facing the upper wall 3 of the pair, and both ends of the core 16 are rotatably held.
