Description
도 2는 본 발명의 일 실시예에 따른 보안 장치에 대한 측단면도이다.
도 3 (a)는 본 발명의 보안 장치를 반사광을 통해 확인하는 과정을 나타낸 도면이고, 도 3 (b)는 반사광을 통해 본 발명의 보안 장치를 확인하였을 때, 일면의 이미지와 이면의 이미지가 결합되어 새로운 이미지가 형성된 상태를 도시한 도면이다.
도 4는 투명시트 내에 불투명시트가 배치될 수 있는 다양한 실시예에 대하여 도시한 도면이다.
도 5 (a)는 불투명 시트를 포함하는 본 발명의 보안 장치를 반사광을 통해 확인하는 과정을 나타낸 도면이고, 도 5 (b)는 반사광을 통해 본 발명의 보안 장치를 확인하였을 때, 다른 이면의 이미지는 불투명시트에 의해 차단되고 일면의 이미지만 나타난 상태를 도시한 도면이다.
도 6 (a)는 불투명 시트를 포함하는 본 발명의 보안 장치를 투과광을 통해 확인하는 과정을 나타낸 도면이고, 도 6 (b)는 투과광을 통해 본 발명의 보안 장치를 확인하였을 때, 일면의 이미지와 이면의 이미지가 결합되어 새로운 이미지가 형성된 상태를 도시한 도면이다.
