プを自由に操作できない欠点があった。However, in the method using X-rays, the equipment such as the X-ray generator is expensive, and
There is a drawback that a technician with X-ray handling qualification must operate, and the ultrasonic method has a large reflection signal from the surface material of the wall material such as gypsum board, making it difficult to detect internal streaks. Since the process of detecting the streaks from the complicated waveform of the sound wave echo is complicated, there is a drawback that the device is expensive, and the fiberscope method has a drawback that the fiberscope is used because of the filling material such as the heat insulating material in the wall. There was a drawback that it could not be operated freely.

Since it detects changes in capacitance, it can detect columns directly under the wall, but cannot detect capacitance changes as the wall becomes thicker, and cannot be used as a device for detecting streaks. There was a flaw.

The output of the comparator 7 is at H
Invert from level to L level. That is, the light emitting diode 9 of the display element is turned on, and the presence of the pillars 35, the studs 36 and the scales 37 is displayed. If the lighting of the light emitting diode 9 is continuously turned on when the second electrode plate 2 is moved in the vertical direction at the lighting position of the light emitting diode 9, this is obviously the pillar 35 or the stud 36. If the judgment can be made, and if the light emitting diode 9 is turned off, then the “Shinkai 37
There exists. ” If the second electrode plate 2 is moved up and down and the light emitting diode 9 is sufficiently turned off at the position where the second electrode plate 2 is further moved left and right, the light emitting diode 9 is turned on.
