Abstract

A wireless IC tag mounted on a low magnetic permeability material is mounted on a holding part which has first and second surfaces and is made of a high magnetic permeability material. The holding part has a penetrating part which penetrates the first and second surfaces, and a notch which penetrates a part of the first and second surfaces at a periphery. A discontinuous region is formed on the holding part due to the notch, and at least on the penetrating part, the wireless IC tag is tightly held together with the low magnetic permeability material. An axis of reverse direction magnetic flux generated by an eddy current that flows in the periphery of the penetrating part and the notch is shifted from an axis of the magnetic flux produced by electromagnetic waves directed toward the wireless IC tag on the first and second surfaces.

Claims

1. A fastening article with a wireless IC tag, comprising:

a holding part which has first and second surfaces and is made of a high magnetic permeability material, the holding part holding the wireless IC tag mounted with a low magnetic permeability material, and the first surface being opposite and spaced apart from the second surface, wherein

the holding part has a passage which is defined between the first and second surfaces so as to open the first and second surfaces, respectively,

a notch which divides a periphery of the passage along the first surface and the second surface and extends between a part of the first and second surfaces that continue in the periphery of the passage is provided,

a discontinuous region is formed on the holding part in the periphery of the passage due to the notch, and

the wireless IC tag with the low magnetic permeability material is tightly held together in said notch and in said passage.

2. The fastening article with the wireless IC tag according to claim 1, wherein an axis of a magnetic flux accompanied by a carrier emitted to the wireless IC tag and an axis of a magnetic flux generated by an eddy current flowing in the periphery of the passage and the notch, the latter magnetic flux being in an opposite direction to the former magnetic flux, are deflected with respect to the first surface and the second surface.

3. The fastening article with the wireless IC tag according to claim 1, wherein the wireless IC tag is accommodated in an accommodating member formed of a low magnetic permeability material;

the accommodating member is composed of a first accommodating member and a second accommodating member; and

the first accommodating member and the second accommodating member sandwich the wireless IC tag.

4. The fastening article with the wireless IC tag according to claim 3, wherein the fastening article is a slide fastener, and a holding part of the wireless IC tag is a slider of the slide fastener.

5. The fastening article with the wireless IC tag according to claim 4, wherein the slider has an upper plate, a lower plate, and a connecting post for connecting the upper plate and the lower plate;

and the passage and the notch are provided at an edge of the lower plate.

6. The fastening article with the wireless IC tag according to claim 4, wherein the slider has a pull tab and a pull tab attaching post for attaching the pull tab;

the pull tab attaching post has a front post and a rear post which are separated to a front and a rear with respect to the slider, and the passage and the notch are provided between opposing end faces of the front post and the rear post.

7. The fastening article with the wireless IC tag according to claim 3, wherein the fastening product is a slide fastener, and a holding part of the IC tag is a pull tab of the slide fastener.

8. The fastening article with the wireless IC tag according to claim 3, wherein the fastening product is a button, and a holding part of the wireless IC tag is a main body of the button.

9. The fastening article with the wireless IC tag according to claim 3, wherein the fastening article is a button;

the button has a circular base part and a covering member integrally fixed to a peripheral part of the base part; and

the passage and the notch are provided at the peripheral part of the base part.

10. The fastening article with the wireless IC tag according to claim 3, wherein the fastening product is a button, and a holding part of the wireless IC tag is an eyelet of the button.

11. The fastening article with the wireless IC tag according to claim 1 or 2, wherein the wireless IC tag has data for discriminating the real from the false.

12. The fastening article with the wireless IC tag according to claim 1 or 2, wherein the wireless IC tag has data for distribution management.

13. The fastening article with the wireless IC tag according to claim 1, wherein a shielding member made of a high magnetic permeability material for shielding the passage to interrupt communication is attached on a transmitting/receiving face of the holding part made of a high magnetic permeability material with respect to an external reader/writer.
