FLEXIBLE TYING MEMBER FOR THEFTPROOF DEVICE

摘要

TITLE OF THE INVENTION FLEXIBLE TYING MEMBER FOR THEFTPROOF DEVICE A flexible tying member for a theftproof device which is adapted to give warning in response to a change in a photo signal transmitted in an optical fiber extending through the flexible tying member. The flexible tying member has a first layer including the optical fiber and at least one electric fire connected to at least one photoelectric element, and a second layer including a reinforcing member. The flexible tying member has a coaxial structure having an inner layer formed by the above first layer, and an outer layer formed by the above second layer, or a parallel structure in which the above first and second layers longitudinally extend parallel with each other.
