<p>PROBLEM TO BE SOLVED: To solve such a problem that discrimination of a signal transmission line is hitherto a work having the possibility of making a mistake on a signal transmission line to be discriminated, exhausting nerves and requiring much labor because it is done by reading the content of a tag by human's eyes referring to a wiring information list. SOLUTION: A tag reader/writer 15 transmits wiring information of an optical cord inputted from a key 15a as inquiry wiring information from an antenna 16 to an RF-ID tag 8 by an electromagnetic wave. A CPU 12 of the RF-ID tag 8 collates the received inquiry wiring information with characteristic wiring information read out from an EEROM 13, and emits light from an LED 11 when both wiring information coincides with each other as the result of collation. When both wiring information coincides with each other as the result of the collation, the CPU 12 transmits a coincidence signal from an antenna part 14 to the tag reader/writer 15. When receiving the coincidence signal, the tag reader/writer 15 emits a buzzer sound through a sound penetration hole 15b.</p> |
