2. Description of the Related Art Termites have negative phototacticity (dislike light), so they make nests in dark places that are hard to see, so it is very difficult to tell that they have entered a house. Therefore, in reality, residents often notice for the first time when winged insects (feather ants) fly out of their nests in the spring, but at that time, the damage is quite aggressive and it is often difficult to respond.

Currently, methods for detecting termites at an early stage include “cavity sound inspection” of structures that may be harmed,
Methods such as "terminating sound of termites and sound of activity", "visual investigation" under the floor, and "periodic visual inspection by burying detection wood near the entrance route of the building" have been implemented.

In order to carry out the "cavity sound inspection" and the "detection of food damage sound and activity sound" of the above-mentioned conventional termite early detection methods, a person with specialized knowledge goes to the site,
Since it is necessary to investigate all the target substructures of the building, it is enormous cost and time-consuming, and in the case of the method of detecting termite noise and activity sound, when termite activity is inactive (particularly in winter) )-Reliable detection was difficult in the time zone. It is generally said that termites are most active from the evening to midnight from April to October, although there are differences depending on the area. It is difficult to detect other than the time and time zone.

[0005] Also, since the space under the floor is often narrow due to recent construction methods, it is difficult to enter under the floor and "visual inspection" is very difficult to carry out. In a bathroom where termites are said to be most vulnerable to damage, they cannot be placed under the floor and visual inspection is practically impossible. In the method of `` burying detection wood near the entrance route of the building and periodically inspecting it '', a vendor regularly visits and pulls out a considerable number of detection wood per house from the soil and checks it visually. Is necessary, so it costs a lot of money and time.

The fitting between the lower case 2 and the detection wooden part 13 is as follows.
A structure is provided in which a gap 17 of about 3 mm is provided and held. Since termites have a property called aerosolity (initiating the damage from the contact portion of the wood), providing a gap between the lower case 2 and the detection wooden portion 13 is not sufficient to attract the termites. Is effective. The lower case 2 is provided with a space 18 below the detection wooden part 13, and an attractant such as a signpost bepheromone is put in the space 18 when strongly attracting termites.

3 is not damaged, the output to signal line 14 is OF
Since the output is F, there is an advantage that power consumption is small. When a large number of sensors are installed and input is made to one control unit, there is an advantage that simple parallel connection is required.

FIG. 2 is a plan view of the detection wooden part 13. As shown in FIG.
As a material of the detection wooden part 13, pine wood, which is most preferred by termites, is optimal. Termites first attack the soft spring lumber along the tree rings, leaving the hard autumn lumber, leaving scratches on the planks as if thin plates were piled up, resulting in a decrease in strength in the direction perpendicular to the planks. Is remarkable. For this reason, the detection wooden part 13 uses a plate having a grain surface, and is 3 m in order to take advantage of the anterotacticity which is a characteristic of termites.
About m cut grooves 21 are provided. The cut groove 21 becomes a condition for attracting termites, and causes a rapid decrease in strength when the detection wooden part 13 is attacked by termites against the pressing force of the push rod 12. This is an important feature of the present invention.

FIG. 3 shows another embodiment. The configuration of the magnetic circuit / detection wooden part 13 and the like in FIG. 1 is almost the same, but concrete is struck under the floor and the ground is not exposed.
The structure makes it easier to attract termites. Only the differences will be described below. The lower surface of the lower case 21 is flat, and an enclosure 22 is provided on the outer periphery. Earth and sand 23 is placed in a groove between the case and the enclosure 21 to make it easier to attract termites. The enclosure 21 is provided with a large number of penetration holes 24 so that termites can easily enter. The intrusion hole 24 is not provided in the lower part, and has a structure in which the moisture contained in the soil 23 does not leak at the time of installation. As a result, termites that have entered the room are easily sucked by the sensor of the present invention, and early detection and handling are possible. Reference numeral 26 in FIG. 3 shows an embodiment in which a magnetic shield material is provided on the outer periphery so that the internal magnetic circuit is not affected by an external magnetic field.
