<p>PURPOSE: To provide a device where safety ability for illicit access is improved compared to a known device by containing a conductive route or the like which is cut by means of an operation for piercing one of side plates for trying to make intrusion into a casing. CONSTITUTION: This device includes a casing constituted of an upper plate P1, the side plates P2-P5 and lower plate P6. Meandered conductive line parts are provided on the inner surfaces of the plates P1-P6, and conductors extending from the upper plate P1 are provided as a part of a mutual connection means and the conductive line parts. When the safety device 10 is once assembled, any attempt to remove the upper plate P1 ends up with the cutting of the conductors. An attempt to rotate the side plate P5 inward is inhibited by the side plates which are arranged by end parts to sides. An attempt to rotate it outward brings the damage to or destruction of conductor areas connected by a weak electric conductive material.</p> |
