In this conventional technique, when the structure of the removal detection is sensed, when removing, for example,
When the thin holding plate 12 is inserted between the device 1 and the wall 2, the switch 9 does not operate, and the device can be taken out as a normal device.

器取外し検出機構を提供することを目的とする。As described above, the above-described prior art has a drawback that when the switch is taken out while holding down the lever, it can be used as a device similar to a normal device. The present invention eliminates this drawback and provides a device removal detection mechanism that can reliably detect the removal of the device by operating the switch whenever it is removed, and control to stop the normal device operation.

As a result, even if a concealed screw is detected by a person who is about to steal, if the concealed screw is loosened, the switch will operate reliably because the plate will push the switch lead by the repulsive force of the screw lead and spring. Thus, the removal of the device can be reliably detected.

It is attached to the wall 2. The lid 3 is located at the center of the front of the device 1.
To hide the hidden screw unit 4 installed inside. The lid 3 is better provided with a key. Equipment 1
When the cover 3 is removed from the wall 2, the cover 3 is removed and the screw 6 of the hidden screw unit 4 is rotated in the removing direction with the special screwdriver 5. When the lead of the screw 6 and the repulsive force of the spring 7 cause the plate 8 to move the lead 10 of the switch 9 Push. The lead 10 presses the switch 9, and when the switch 9 is operated, the detecting circuit 11 that is linked is operated, and the device does not operate normally.

に適用でき、その応用範囲は広い。As described above, according to the present invention, theft is prevented by the hidden screw. However, even if the hidden screw is detected and theft occurs, the removal of the equipment is reliably detected and the normal equipment is removed. Since control is performed so that performance is not exhibited, in the case of a wireless device or the like, it is possible to prevent radio wave interference, radio wave jack, and the like. Further, the present invention is not limited to a wireless device, but can be applied to general electronic devices mounted on a wall or a table, and its application range is wide.
