The tag 5 has a required circuit 7 formed on one surface of a base 6 made of an insulating film such as a polyester film. The circuit 7 will be described. Reference numeral 8a denotes a large U-shaped conductor pattern layer formed of a good conductor such as metal, and reference numeral 8b denotes a small U-shaped conductor pattern layer. Both conductor pattern layers 8a,
8b are electrically connected by the connection layer 9. Also,
In this case, a Schottky type thin film diode 10 is formed between the conductor pattern layers 8a and 8b. When the tag 5 having such a structure receives an electromagnetic wave of a predetermined frequency, the thin film diode 10 functions as a kind of transmitter that converts the frequency of the received electromagnetic wave and retransmits the electromagnetic wave of a certain frequency.

In the tag 5, the conductor patterns 8a and 8b and the thin film diode 10 can be formed by a pattern forming technique and a thin film forming technique, respectively. It is rich in sex.

The tag 5 is buried inside the cover 3 of the book body 2 as described above.
As shown in FIG. 2, a cover 13 is provided on the inner surface side of the cover 3, that is, on the facing portion 4, and the tag 5 is closed by the cover 13. For this reason, the tag 5 will not be seen by the person who holds the book even when the cover 3 is opened, from the outside.

In the book 1A having the above configuration, the tag 5 is provided in the cover 3 when the book body 2 is bound, so that the provision of the anti-theft function is already completed in the bookbinding process.

In the book 1A having the above structure, a person
If the user tries to leave the book 1A in an outlet or the like of a store or a library in the above state, the tag 5 (circuit 7) responds to an electromagnetic wave transmitted from an electromagnetic wave source of a specific frequency provided at the outlet or the like. Therefore, it retransmits an electromagnetic wave of a specific frequency, although the frequency is different. Therefore, by installing a receiving device for detecting the retransmitted electromagnetic wave at the exit or the like, it is possible to sound a buzzer or close the exit door based on a signal from the receiving device. Shoplifting or unauthorized removal of the book 1A can be prevented.

Further, as described above, since the provision of the anti-theft function has already been completed in the bookbinding process, it is not necessary for a book store clerk or a librarian to attach an anti-theft tag to each book. The time and effort required can be completely eliminated.

Moreover, the tag 5 is provided inside the cover 3, so that the tag 5 can be seen even if the book 1A is picked up and the cover 3 is opened, as a matter of course. There is no unpleasant impression on visitors and visitors.

The tag 5 is provided with an electromagnetic wave retransmission function of the tag 5 by applying an excessive current to the thin film diode 10 to puncture the diode 10 or by punching the diode 10 or a connecting portion. Will be destroyed. Therefore, a person who has purchased or borrowed the book 1A properly can leave without detecting the exit or the like by the clerk or the clerk breaking the circuit 7 of the tag 5.

As means for destroying the retransmitting function of the electromagnetic wave of the tag 5 as described above, in addition to the above-mentioned means, a fuse portion operating at a frequency different from the frequency of the electromagnetic wave for detection is formed in the circuit 7. The tag may be irradiated with the electromagnetic wave of the frequency to destroy the fuse portion, thereby destroying the resonance circuit. Alternatively, heat is generated by a specific frequency,
It is also possible to adopt a configuration in which the fuse is cut by the heat.
