METHOD FOR IDENTIFYING OBJECTS TO BE IDENTIFIED, ITS ELECTROSCOPE, AND AN INPUT CIRCUIT OF THE ELECTROSCOPE

摘要

When identifying particular cable A among a plurality of cables housed in a trough, a signal applying section 10 compounds three different frequency signals, which are generated by an oscillating circuit section 11, by a potential signal compounding /A applying circuit 15 and applies it to conductor A1 of the particular cable A. In a detecting section 20, a detecting circuit 22 detects the compound signal via an electrode 21, which is electrostatically coupled with particular cable A, an amplifying circuit 23 subjects the compound signal to gain adjustment, and a signal identifying circuit 24 identifies particular cable A from the compound signal.
