This application claims priority to Japanese Patent Application No. 2003-070532 filed Mar. 14, 2003 which is hereby expressly incorporated by reference herein in its entirety.
A second mode of the invention is different from the first mode of the invention in that the contactless identification tag includes a detection result transmission means to transmit information indicating detachment of the tag to the reader-writer device when the detachment detection means detects that the contactiess identification tag is detached from a given object.
That is, the contactless identification tag transmits information indicating the detachment to the reader-writer device, when the contactiess identification tag is detected as being detached from the given object.
A sixth mode of the invention is the contactless identification tag in the contactiess communication system according to the first mode of the invention. The contactless identification tag includes a driving electric power generation means that generates driving electric power from electromagnetic waves for supplying power transmitted from the reader-writer device, an attachment means to attach the contactless identification tag to a given object, a detachment detection means to detect whether the contactless identification tag attached to the given object by the attachment means is detached from the given object or not and a specific information display means to display the specific information based on the detection result obtained by the detachment detection means.
The present mode provides the contactless identification tag in the contactiess communication system according to the second mode of the invention. Its functional operations being already described, the description is omitted here.

[0052]FIG. 5(a) is a figure showing the circuit composition of the contactless identification tag, while FIG. 5(b) is a sectional view along the line A-A in FIG. 5(a).
[0053]FIG. 6(a) is a sectional view along the line A-A when the contactless identification tag 3 shown in FIG. 5 is attached to a piece of baggage 4, while FIG. 6(b) is a figure showing the state in which the contactless identification tag 3 is detached from the baggage 4 in the sectional view FIG. 6(a).
[0054]FIG. 7 is a flow chart showing the function operation of the data communication device 2.

The detachment detection part 35 functions to detect that the contactiess identification tag 3 once attached to the baggage 4 is detached, as a voltage change in the voltage monitoring part 34.
[0089]FIG. 5(a) is a figure showing the circuit composition of the contactless identification tag, FIG. 5(b) is a sectional view along the line A-A in FIG. 5(a). FIG. 6(a) is a sectional view along the line A-A when the contactless identification tag 3 shown in FIG. 5(a) is attached to the baggage 4. FIG. 6(b) is a figure showing the state in which the contactless identification tag 3 shown in FIG. 5(a) is detached from the baggage 4 in the sectional view of FIG. 6(a).
As shown in FIG. 5(a), the circuit composition of the contactless identification tag 3 includes a substrate 300 b and a coil antenna 39. Formed on the substrate 300 b, the coil antenna 39 is made of a whirl-like (concentric) metal wire with one stroke sketch (continuous) along the surrounding of the substrate 300 b. According to the embodiment of the present invention, the coil antenna 39 is formed by the ink-jet method using a metal ink.
At the center of the substrate 300 b, the control part 3 b is mounted as an IC chip, and the electrophoresis display part 37 is also mounted. Coupled to the control part 3 b with a wiring 300 a as shown in FIG. 5(b), a detachment detection circuit part 300 is provided. In the detachment detection circuit part 300, a wiring 300 d of the first detective resistor part 35 a is formed so that it can be conductive to the wiring 300 a, while being adjacent to the wiring 300 a. An adhesion part 300 c in the figure adheres the contactless identification tag 3 to the baggage 4.
That is, as shown in FIG. 6(a), the contactiess identification tag 3 is adhered to the baggage 4 by the adhesion part 300 c. Here, the adhesion part 300 e of the first detective resistor part 35 a is formed in such a way as it can be separated from the other adhesion part 300 c. As shown in FIG. 6(b), when the contactless identification tag 3 is detached from the baggage 4, the first detective resistor part 35 a, accompanied by the wiring 300 d and the adhesion part 300 e, is left on the baggage 4, separated from the body of the contactiess identification tag 3, because the wiring 300 d is adhered to the wiring 300 a with weaker adhesion strength with that to the adhesive part 300 c.
When the contactless identification tag 3 is detached from the baggage 4, the first detective resistor part 35 a is separated from the body, as shown in FIG. 6(b). Then, in this state, if the contactless identification tag 3 receives the response request signal from the reader-writer device 2, it generates driving electric power from carrier waves of the signal in the power supply generation part 38 and supplies the power to each part of the contactless identification tag 3, in the same way as described above. Thereby, in the voltage monitoring part 34, to which electric power is supplied, a change of the voltage E3 is detected, and it is informed to the data control part 32. When the data control part 32 receives the information, it judges that the contactless identification tag 3 is detached from the baggage 4, and transmits a command to the display processing part 36 to make the electrophoresis display device 37 display the information indicating the detachment.
the contactiess identification tag including:
6. In a contactless data communication system, a contactiess identification tag comprising:
a detachment detection means that detects whether the contactiess identification tag attached to the given object by the attachment means is detached from the attachment means; and
