Abstract

The present invention relates to an IC tag housing case configured to house an IC tag therein, and the objective thereof is to accurately exchange information between an IC tag and a reader/writer without increasing costs for an IC tag. To this end, an IC tag housing case is configured to include a lid body formed of a material that allows electromagnetic waves to pass therethrough, and a case body having a space portion where an IC tag is housed and formed of a high magnetic permeability material.

Claims

1. An IC tag housing case comprising a high magnetic permeability member formed of a high magnetic permeability material and disposed so as to oppose a portion in which an IC tag may be placed.

2. The IC tag housing case of claim 1, wherein a relative magnetic permeability of the high magnetic permeability material is from 1,000 to 800,000.

3. The IC tag housing case of claim 1, wherein the high magnetic permeability material is at least one of a group consisting of permalloy, nickel, and cobalt.

4. The IC tag housing case of claim 1, wherein an antenna composed of a passive component is provided on a face where the high magnetic permeability member is absent.

5. The IC tag housing case of claim 1, in combination with an IC tag, wherein the IC tag is attached to the portion.

6. An IC tag housing case comprising:

a case body formed of a high magnetic permeability material and defining a space portion in which an IC tag may be placed; and

a lid body arranged so as to cover the space portion and subjected to an incoming electromagnetic wave.

7. The IC tag housing case of claim 6, wherein a relative magnetic permeability of the high magnetic permeability material is from 1,000 to 800,000.

8. The IC tag housing case of claim 6, wherein the high magnetic permeability material is at least one of a group consisting of permalloy, nickel, and cobalt.

9. The IC tag housing case of claim 6, wherein the lid body is configured as attachable to and detachable from the case body.

10. The IC tag housing case of claim 6, wherein the lid body is provided with an antenna composed of a passive component.

11. An IC tag housing case comprising:

a case body defining a space portion in which an IC tag may be placed;

a lid body arranged to cover the space portion and subjected to an incoming electromagnetic wave; and

a high magnetic permeability member formed of a high magnetic permeability material and disposed in the case body so as to oppose the space portion.

12. The IC tag housing case of claim 11, wherein a relative magnetic permeability of the high magnetic permeability material is from 1,000 to 800,000.

13. The IC tag housing case of claim 11, wherein the high magnetic permeability material is at least one of a group consisting of permalloy, nickel, and cobalt.

14. The IC tag housing case of claim 11, wherein the lid body is configured as attachable to and detachable from the case body.

15. The IC tag housing case of claim 11, wherein the lid body is provided with an antenna composed of a passive component.
