Abstract

A non-authentic article discrimination system for discriminating whether an article to which an IC tag is attached is a non-authentic article includes an IC tag and a base device. The IC tag includes a first antenna portion for receiving a radio wave, a power generation circuit for generating electric power from the radio wave received by the first antenna portion, a first storing portion for storing information regarding the article, and a radio wave output circuit for outputting a radio wave including the information stored in the first storing portion via the first antenna portion. The base device includes a second antenna portion for receiving the radio wave transmitted from the first antenna portion and transmitting a radio wave generated in the base device toward the IC tag, a second storing portion for storing information regarding the article, the information stored in the second storing portion being the same as the information stored in the first storing portion, a discriminating portion for discriminating whether the first information included in the radio wave received by the second antenna portion coincides with the information stored in the second storing portion, and a displaying portion for displaying a discrimination result of the discrimination portion.

a discriminating portion for discriminating whether the first information included in the radio wave received by the second antenna portion coincides with the information stored in the second storing portion; and

a displaying portion for displaying a discrimination result of the discrimination portion.

2. The non-authentic article discrimination system as recited in claim 1, wherein the information stored in the first storing portion and the information stored in the second storing portion are the same manufacturer ID code of the article.

3. The non-authentic article discrimination system as recited in claim 1, wherein the base device further includes an alarm device which makes warning sound depending on the discrimination result.

4. A non-authentic article discrimination system for discriminating whether an article to which an IC tag is attached is a non-authentic article, the non-authentic article discrimination system, comprising:

an IC tag; and

a base device,

wherein the IC tag includes;

a first antenna portion for receiving a radio wave;

a power generation circuit for generating electric power from the radio wave received by the first antenna portion;

a first storing portion for storing information regarding the article; and

a receiving circuit configured to receive the radio wave received by the first antenna portion;

a discrimination circuit for discriminating whether the information stored in the first storing portion coincides with information regarding the article included in the radio wave received by the receiving portion; and

and a light-emitting diode for emitting light depending on a discrimination result of the discrimination circuit,

wherein the base device includes;

a second storing portion for storing information regarding the article, the information stored in the second storing portion being the same as the information stored in the first storing portion;

a second antenna portion for transmitting the radio wave including the information stored in the second storing portion toward the IC tag; and

a radio wave supplying circuit for supplying the radio wave including to the information stored in the second storing portion to the second antenna portion.

5. The non-authentic article discrimination system as recited in claim 4, wherein the information stored in the first storing portion and the information stored in the second storing portion are the same manufacturer ID code of the article.

10. The non-authentic article discrimination system as recited in claim 4, further comprising a computing circuit for computing the information stored in the first storing portion depending on a discrimination result of the discrimination circuit.

6. A non-authentic article discrimination system for discriminating whether an article to which an IC tag is attached is a non-authentic article, the non-authentic article discrimination system, comprising:

an IC tag; and

a base device,

wherein the IC tag includes;

a first antenna portion for receiving a radio wave;

a power generation circuit for generating electric power from the radio wave received by the first antenna portion;

a first storing portion for storing information regarding the article; and

a receiving circuit configured to receive the radio wave received by the first antenna portion;

a discrimination circuit for discriminating whether the information stored in the first storing portion coincides with information regarding the article included in the radio wave received by the receiving portion; and

and a radio wave transmitting portion for transmitting a radio wave including the information stored in the first storing portion via the first antenna portion depending on a discrimination result of the discrimination circuit,

wherein the base device includes;

a second storing portion for storing information regarding the article, the information stored in the second storing portion being the same as the information stored in the first storing portion;

a second antenna portion for transmitting a radio wave including the information stored in the second storing portion toward the IC tag;
