防止伪造变造装置
摘要：
本发明涉及防止伪造变造装置。根据本发明的防止伪造变造装置，包括磁性可变物质含有部场(B)发生变化时，所述磁性可变物质(10)的反射光或透射光(L)发生变化；磁场产生部(200)，设置于磁性可变物质含有部(100)的下部，产生向磁性可变物质(10)施加磁场(B)；以及颜色可变部(500,600,700)，设置于磁性可变物质含有部(100)的上部，或介于磁性可变物质含有部(100)和磁场发生部(200)之间，通过外部刺激(E,P)使从磁性可变物质含有部(100)反射或透射光发生变化(L1->L2-L7)。(100)，其含有磁性可变物质(10)，当所施加的磁
摘要（英）：

According to the present invention, an apparatus for preventing counterfeiting and alteration includes a magnetic variable material (100) including unit which includes a magnetic variable material (10) wherein reflected light or transmitted light changes when applied magnetic fields (B) change; a magnetic field generation unit (200) which generates the magnetic fields which can be applied to the magnetic variable material (10); and a spacer which is interposed between the magnetic variable material including unit and the magnetic field generation unit, and controls a distance between the magnetic variable material including unit and the magnetic field generation unit, thereby changing the light reflected or transmitted in the magnetic variable material including unit.
