Abstract

An IC tag searching apparatus capable of changing the shape of its searching board in a simple manner in accordance with the situations of a location to be searched, said location includes wide to narrow areas and areas in the corners, at the time of searching the positions of wireless IC tags those which are embedded in a concrete construction and the like, efficiently detecting the positions of the embedded wireless IC tags and performing reading and writing of information from/to the wireless IC tags is provided. The IC tag searching apparatus 10 according to the present invention comprises a plurality of plate members 2, 3 each having an antenna built-in, said plate members may be joined with each other in a direction of those flat surfaces, respectively, a joining means provided to the plate members having an antenna built-in and information transmission/reception section 11 for performing data transmission/reception between the plate member having an antenna built-in and the R/W main body 9.

Dependent claims

An IC tag searching apparatus comprising;

a plurality of plate members each having an antenna built-in, said plate members being joined in a direction of those flat surfaces and separated from one another, and further provided with a radio means for detecting IC tags, respectively,
a joining means adapted to join the plate members each having an antenna built-in one another and being provided to the plate member having an antenna built-in, wherein said joining means is a concave/convex interdigitation means formed in a lateral side of said plate member having an antenna built-in;
a terminal section for electrically connecting the plate members one another is formed in the lateral side of said plate member, and
an information transmission/reception section for performing data transmission/reception between the plate member having an antenna built-in and an insertion type reader/writer main body, wherein said information transmission/reception section performs transmission and reception of signals between said section and the insertion-type reader/writer main body that inserted into said plate member having an antenna built-in.
