いる。Further, a low frequency signal generating mechanism section of 50 KHz or less is attached to the glass plate 21 via a frame 22 and a holder 35. The generation of a low frequency signal is basically obtained by dropping a metal ball from a predetermined height. A metal ball 27, for example an iron ball having a diameter of about 11 mm, is positioned at a predetermined location on the glass plate 21 with its circumference regulated by a cylindrical member 28. The cylindrical member 28 is fixedly supported by a holder 35 attached to the frame 22,
A suction nozzle 29 is slidably fitted into the cylindrical member 28 .

Therefore, in FIG. 3, the lower end surface of the suction nozzle 29 is normally located above the metal ball 27 by a predetermined height. The other end of the tube 34 communicating with the vacuum suction hole 30 of the suction nozzle is connected to a vacuum pump 38, and the suction nozzle is normally in a state where vacuum suction is possible.

As the motor 33 rotates, the suction nozzle 29 approaches the metal ball 27 to a predetermined height and is configured to suction the metal ball 27 to the end of the nozzle. Note that the means for fixedly supporting the motor 33 is omitted in FIG. 3. To check the operating characteristics of the glass breakage sensor 1 described above, first, apply a liquid material 36 made of silicone oil, water, etc. to a predetermined location on the glass plate 21, and then apply the glass breakage sensor to the surface where the liquid material is applied. The glass breakage sensor 1 is mounted by pressing it with a predetermined pressure so that the three surfaces of the metal plate 1 are in contact with each other.

With the glass breakage sensor 1 attached, the external connection terminal 11 of the glass breakage sensor 1 and the signal measuring device 26 are electrically connected, and the high frequency signal generator 25 and the high frequency signal transmission element 24 are connected.
When a signal of 100 KHz or higher is generated through the glass breakage sensor 1 , the glass breakage sensor 1 detects the high frequency signal propagated through the glass plate 21 and transmits a predetermined waveform signal to the measuring device 26 .

伝播する。When the measuring device 26 detects and displays a predetermined signal, it means that the glass breakage sensor 1 and the glass plate 21 have obtained an adhesion state that approximates the actual usage state, and
This means that the operation test preparation is complete. Next, a predetermined high frequency signal is supplied to the glass plate 21 in the above-mentioned state, and the suction nozzle 29 is connected to the solid line arrow A through the cam 32.
After the metal ball 27 is vacuum-adsorbed,
When the metal ball 27 is raised again and the metal ball 27 reaches a predetermined height, the vacuum suction is turned off and the metal ball 27 is dropped.
A low frequency signal of 50 KHz or less is generated and propagates through the glass plate 21.

Two types of signals, one above the pressure and one below the 5th pressure, are simultaneously supplied to the glass breakage sensor. As a result, the glass breakage sensor 1 catches both signals and displays a waveform signal of a predetermined mode on the measuring device 26. That is, the operating state of the glass breakage sensor can be tested and confirmed. After the operation test has been completed, the glass breakage sensor 1 is removed from the glass plate, and the liquid material adhering to the metal plate 3 is wiped off with a cloth or the like to complete the product. The liquid member 36 used in the above operation test serves to temporarily bond and fix the glass plate and the glass breakage sensor, and is used for the purpose of firmly adhering the two members like a normal epoxy adhesive. It's not a thing.

As described above, the present invention can be easily implemented without fixing a glass breakage sensor to a glass plate with an adhesive, and can stably measure operating characteristics.
