Abstract

A new type of RFID tag is provided. A gaming chip that incorporates a sticker-type RFID tag comprises: an enclosing member having a predetermined shape for enclosing the RFID tag; a body member that is injection-molded to encapsulate the enclosing member with the RFID tag; and a gaming chip for amusement. The enclosing member consists of a first part and a second part, and at least the first part or the second part has a flat surface to which a sticker-type RFID tag can adhere, and the first part and the second part are combined to form an enclosing member, in which the sticker-type RFID tag is covered by the first part and the second part.

First claim

The invention claimed is:

1. A gaming chip that incorporates a sticker-type RFID tag, the gaming chip comprising:
an enclosing member having a predetermined shape that encloses the sticker-type RFID tag;
a body member that is injection-molded to enclose the enclosing member enclosing the sticker-type RFID tag; and
a decal member that represents a type or denomination of the gaming chip,
wherein:
the enclosing member consists of a first part and a second part,
at least the first part or the second part has a flat surface to which the sticker-type RFID tag can be adhered,
the first part and the second part are combined so that the enclosing member is formed and the sticker-type RFID tag is enclosed by the first part and the second part, and
at least one air gap is positioned between the sticker-type RFID tag and the first part or the second part.

2. The gaming chip according to claim 1 , wherein the enclosing member is covered on entire surface by the injection-molded body member and the decal member.

3. The gaming chip according to claim 1 , wherein the enclosing member is covered on entire surface by the injection-molded body member.

4. The gaming chip according to claim 1 , wherein:
the enclosing member enclosing the sticker-type RFID tag is located in a central portion of the gaming chip, and
the decal member is located in a peripheral portion in a thickness direction of the gaming chip.

5. The gaming chip according to claim 1 , wherein the sticker-type RFID tag stores information about the gaming chip, and is readable when a plurality of gaming chips are stacked.

6. The gaming chip according to claim 1 , wherein the sticker-type RFID tag is enclosed within plus or minus 25% of a thickness of the gaming chip from the center of a thickness direction of the gaming chip.

7. The gaming chip according to claim 1 , wherein the first part and the second part are combined to form a sealed space for enclosing the sticker-type RFID tag.

8. The gaming chip according to claim 7 , wherein the sealed space for enclosing the sticker-type RFID tag is configured by press-fitting the first part into the second part.

9. The gaming chip according to claim 7 , wherein the sealed space for having the sticker-type RFID tag therein is configured by engaging the first part and the second part with each other.

10. The gaming chip according to claim 7 , wherein the sealed space for having the sticker-type RFID tag therein is configured by gluing the first part and the second part with each other.

11. The gaming chip according to claim 1 , wherein the enclosing member enclosing the sticker-type RFID tag is configured by sandwiching the sticker-type RFID tag between the first part and the second part.

12. The gaming chip according to claim 11 , wherein the enclosing member enclosing the sticker-type RFID tag is configured by sandwiching the sticker-type RFID tag between the first part and the second part and gluing the first part and the second part.

13. The gaming chip according to claim 1 , wherein the first part and the second part are connected to each other.

14. The gaming chip according to claim 13 , wherein the first part and the second part are connected in a hinged manner.

15. The gaming chip according to claim 1 , wherein a diameter of the sticker-type RFID tag is larger than a diameter of the decal member.

16. The gaming chip according to claim 1 , wherein the specific gravity of the enclosing member is greater than that of the body member.

17. The gaming chip according to claim 1 , wherein the specific gravity of the enclosing member is smaller than that of the body member.

18. The gaming chip according to claim 1 , wherein the enclosing member is configured to be molded into a predetermined shape by injection molding.

19. A method for manufacturing a gaming chip comprising:
a first process of adhering a sticker-type RFID tag to a first part having in advance a flat surface for adhering the sticker-type RFID tag;
a second process of covering the first part to which the sticker-type RFID tag is adhered with a second part to construct an enclosing member that encloses the sticker-type RFID tag, wherein at least one air gap is positioned between the sticker-type RFID tag and the first part or the second part based on construction of the enclosing member; and
a third process of constructing a main body that encloses the enclosing member that encloses the sticker-type RFID tag by using the enclosing member as an insert part and performing insert molding.

20. A gaming chip that incorporates an RFID tag, the gaming chips comprising:
an enclosing member having a predetermined shape that encloses the RFID tag;
a body member that is injection-molded to enclose the enclosing member enclosing the RFID tag; and
a decal member representing a type or denomination of the gaming chip,
wherein:
a first part and a second part are combined to form the enclosing member,
the RFID tag is covered by the first part and the second part,
the enclosing member is covered by the body member and the decal member around the enclosing member, and
at least one air gap is positioned between the RFID tag and the first part or the second part.
