BEST MODE FOR CARRYING OUT THE INVENTION (Embodiment 1) Embodiment 1 will be described with reference to FIGS. 1 to 3. FIG. 1 is a schematic side sectional view of a state in which a seal is attached to a fitting portion of a case as seen from the side, FIG. 2 is a bottom view of the seal, and FIG. 3 is a top perspective view of the seal.

In FIG. 1 to FIG. 3, reference numeral 10 denotes the entire seal, and this seal 10 is provided with a strong adhesive portion 1 having a strong adhesiveness and a strong adhesive portion 1 provided next to the strong adhesive portion 1. Weak adhesive portion 2 having weak adhesive force, IC chip 3 in which ID information is written, antenna 4 for transmitting ID information written in IC chip 3 to an ID reader in a non-contact manner, and writing of ID information Circuit 5 connected to the integrated IC chip and a seal base material 6 forming the surface of the seal 10.
It consists of

Reference numeral 9 denotes a case of an electronic device. The case 9 is composed of an upper case 7 of the electronic device and a lower case 8 of the electronic device fitted in the upper case 7.

Reference numeral 11 is an ID reader for reading the ID information written in the IC chip 3.

Then, the strong adhesive portion 1 and the weak adhesive portion 2 of the seal 10 are alternately arranged adjacent to each other.
0 is case 9 across both upper case 7 and lower case 8.
Pasted on.

The IC chip 3, the antenna 4 and the circuit 5 are also provided.
Is affixed across the strong adhesive portion 1 and the weak adhesive portion 2.

When the seal 10 is peeled off in this state, the strong adhesive portion 1 works to attach to the case 9 side, and the weak adhesive portion 2 works to attach to the seal 10 side. And due to the difference in these forces,
Since the seal 10 is easily damaged between the strong adhesive portion 1 and the weak adhesive portion 2, peeling of the seal 10 can be made difficult.

Further, the force acting between the strong adhesive portion 1 and the weak adhesive portion 2 of the seal 10 is applied to the IC chip 3,
The IC chip 3 is damaged by this force, and the ID information written in the IC chip 3 cannot be read by the ID reader 11. Since the ID information becomes unreadable in this way, it is possible to reliably detect that the seal 10 has been peeled off.

The antenna 4 and the circuit 5 are also ICs.
Like the chip 3, a force acting between the strong adhesive portion 1 and the weak adhesive portion 2 of the seal 10 is applied to the antenna 4 or the circuit 5, and the antenna 4 or the circuit 5 is damaged by this force, and the IC chip 3 The ID information written in the ID cannot be read by the ID reader 11. Thus, the ID
By making the information unreadable, it is possible to reliably detect that the seal 10 has been peeled off.

In this embodiment, the IC chip 3, the antenna 4, and the circuit 5 are shown as straddling the strong adhesive portion 1 and the weak adhesive portion 2, but only one of them is straddled. Even in the case of peeling, it is possible to reliably detect the peeling. Further, the more the number of straddling points, the easier it is to find the peeling.

Further, even after the seal 10 is peeled off and the same seal is duplicated and attached, the signal of the IC chip is detected by using the ID reader 11 and the signal from the IC chip cannot be detected. By detecting a signal different from the original signal, it is possible to reliably find that the seal 10 has been duplicated.

The strong adhesive portion 1 and the weak adhesive portion 2 may be an acrylic adhesive or the like.

The seal base material 6 may be made of a material such as wood free paper that does not have elasticity and does not expand or contract. As a result, when the seal 10 is peeled off, the force acting between the strong adhesive portion 1 and the weak adhesive portion 2 of the seal 10 causes the seal base 6
Is torn and destroyed, the peeling of the seal 10 can be visually confirmed.

(Second Embodiment) A second embodiment will be described with reference to FIG. The same parts as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

The difference from the first embodiment is that the strong adhesive portion 1 and the weak adhesive portion 2 are not provided alternately adjacent to each other, but there is a strong adhesive portion 1 as shown in FIG. ,
The weak adhesive portion 2 is provided around the strong adhesive portion 1.

With the above structure, the strong adhesive portions 1 and the weak adhesive portions 2 are not only provided alternately adjacent to each other. Therefore, no matter which direction the seal 10 is peeled off, the strong adhesive portion 1 is formed. To the weak adhesive portion 2 or from the weak adhesive portion 2 to the strong adhesive portion 1, the seal 10 is more damaged between the strong adhesive portion 1 and the weak adhesive portion 2. Since it is easy to peel, the peeling of the seal 10 itself can be made difficult.

As shown in FIG. 5, the strong adhesive portion 1 may be one instead of plural.

The IC chip 3, antenna 4 and circuit 5
The effect obtained when the is attached over the strong adhesive portion 1 and the weak adhesive portion 2 is similar to that of the first embodiment.

It should be noted that the positions of the strong adhesive portion 1 and the weak adhesive portion 2 in FIGS. 4 and 5 are replaced with each other, and there is a weak adhesive portion 2, and the strong adhesive portion 1 is provided around the weak adhesive portion 2.
May be provided.

The adhesive portions are not limited to the two types of the strongly adhesive portion 1 and the weakly adhesive portion 2 and may be several types of adhesive portions having different adhesive strengths.

The adhesive strength of the strong adhesive portion 1 is stronger than that of the seal base material 6, the IC chip 3, the antenna 4 and the circuit 5, and the weak adhesive portion. When the seal 10 is peeled off from the case 9, the adhesive strength of 2 is stronger than that of the seal base material 6, the IC chip 3, the antenna 4 and the circuit 5 as compared with the adhesive strength of the case 9. The adhesive portion 1 surely remains on the case 9 side, and the weakly adhesive portion 2 surely remains on the seal substrate 6 side. As a result, a force is applied to the IC chip 3 or the antenna 4 or the circuit 5 attached over the strong adhesive portion 1 and the weak adhesive portion 2 to damage them, and the ID information written in the IC chip 3 is written. Can no longer be read,
It can be surely found that the seal 10 has been peeled off.
