Description

도난방지방법 및 장치Anti-theft Method and Device

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 코일틀장치들, 저자회로장치 및 경보장치를 도시한 도난방지 시스템의 투시도.1 is a perspective view of an anti-theft system showing the coil frame devices, the low circuit device and the alarm device.

제5도는 제4도에서 선 5-5를 따라 전송코일과 수신코일을 드러낸 코일틀장치의 단면도.5 is a cross-sectional view of the coil frame device revealing the transmission coil and the reception coil along the line 5-5 in FIG.

제6도는 원조 및 반대모우드의 동작설명을 보조하는 다이어 그램.6 is a diagram to assist in explaining the operation of the aid and the opposing mode.

Claims (6)

감시지대를 통과하는 물건을 탐지하는데 있어서, 상기 감시지대 내에서 문의 진동전자계를 발생시키는 수단과 물건에 부착되고 라벨들의 공간적 방위에 관계없이 상기 발생된 문의 전자계와 차폐 또는 쇄금되게 개작되고 경보를 울리게 개작된 회로수단을 포함하는 도난방지장치.In detecting the object passing through the surveillance zone, the means for generating a vibrating electromagnetic field of the door within the surveillance zone and attached to the object and adapted to shield or lock the electromagnetic field of the generated door irrespective of the spatial orientation of the labels and to alarm.
