Mobile terminal

摘要

A mobile terminal includes a case capable of being assembled or disassembled, a printed circuit board (PCB) arranged in the case and having a tamper detection pattern, the tamper detection pattern having a plurality of conductive areas and at least one non-conductive area, a conductive area connection unit arranged between the case and the PCB and electrically connecting a part of the conductive areas during assembly of the case and electrically disconnecting the part of the conductive areas during disassembly of the case, and a conductive area connection detection circuit electrically connected to the conductive areas and detecting an electric connection state between the conductive areas. The conductive areas includes a first conductive area, a plurality of second conductive areas arranged to be separated from one another and connected to the first conductive area via the conductive area connection unit, and a third conductive area, at least a part of which is arranged between the second conductive areas.
