Patent ID: 7271723

Claim:
A closed space apparatus comprising: all of the constituent walls of the closed space provided with a plurality of intrusion detection sensor panels on all of the inner walls of said apparatus, each of said intrusion detection sensor panels having a panel surface to detect an intrusion from any portion of the constituent wall of said closed space apparatus, wherein said plurality of said intrusion detection sensor panels are additionally attachable on all of the inner walls of existing conventional closed space apparatus having no intrusion detection sensor panels, wherein each of the inner walls of said apparatus is provided with said intrusion detection sensor panel over the entire surface of the inner wall without any gaps or lapses, wherein said intrusion detection sensor panel having an entire surface to detect said intrusion comprises: an optical fiber or fine electric wire configured at a prescribed density that covers the entire surface of the inner wall; a signal input unit that inputs a signal into one end of said optical fiber or fine electric wire; and a signal receiving unit that receives said input signal at the other end of said optical fiber or fine electric wire, wherein said intrusion is detected if said input signal is no longer received at the other end by said signal receiving unit in the event that said optical fiber or fine electric wire is broken by an unlawful intrusion through said wall of said closed space apparatus.
