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(100)，其含有磁性可变物质(10)，当所施加的磁场(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)。
摘要（英）：

A device according to the present invention for preventing counterfeiting and falsifying is characterized by comprising: a magnetically variable material including part including a magnetically variable material in which reflected light or transmitted light is changed when an applied magnetic field is changed; a magnetic field generating part for generating a magnetic field that can be applied to the magnetically variable material; and a spacer interposed between the magnetically variable material including part and the magnetic field generating part, and controlling the distance between the magnetically variable material including part and the magnetic field generating part.
