Abstract
The present invention relates to the technology of recognizing and reading each game chip although game chips are stacked. The present invention is a game chip storing data readable by a reader/writer having an antenna which emits an electromagnetic wave and available in a stack of game chips, and includes: an IC device for communicating data at a request from the reader/writer; an antenna electrode connected to the IC device, and configured such that the antenna electrode can enter a resonant state with an antenna of the reader/writer through an electromagnetic wave; and a reflection member for reflecting an electromagnetic wave reflected from the antenna of the reader/writer toward upper game chips in the stack.
Claims9
A game chip comprising:
- a circuit for receiving a data request from a read device and transmitting data in response to receiving a data request from the read device;
- an electromagnetic antenna connected to the circuit for receiving the request for data from the read device as an electromagnetic signal and for transmitting data;
- a body housing the circuit and the antenna;
- an annular protector located at and defining an outer periphery of the game chip and protecting the body;
- and
- an annular electromagnetic wave reflector located between the body and the protector, wherein,
- when a plurality of the game chips are arranged in a stack, each annular electromagnetic reflector of each game chip in the stack forms a part of a stack electromagnetic wave reflector of the stack, reflecting electromagnetic waves radiated by the read device at a first end of the stack, so the electromagnetic waves reach the game chip at a second end of the stack, opposite the first end of the stack, by reflection of the electromagnetic waves from the stack electromagnetic wave reflector of the stack, and
- each chip has a height along an axial direction of the stack of game chips.
A stackable game chip stacked by a game player, with other stackable game chips, in placing a bet in an area of a game table that includes one of a plurality of read devices for reading data stored in game chips and placed on respective areas of the game table including respective read devices , via electromagnetic waves radiated by the read devices, the game chip comprising:
- a circuit receiving data from and transmitting data to a read device in response to a request from the read device;
- a game chip antenna connected to the circuit for communication with the read device, through an antenna of the read device, via electromagnetic waves;
- a body member housing the circuit and the antenna of the game chip;
- an annular protector located at an outer periphery of the body member;
- protecting the body member;
- and
- an annular reflector located between the body member and the annular protector and reflecting electromagnetic waves, wherein, in a stack of a plurality of the game chips placed on the area of the game table having the read device, the annular reflectors of the game chips form an interior wall reflecting the electromagnetic waves radiated from the antenna of the read device so the electromagnetic waves reach the game chip of the stack that is most remote from the game table via reflection from the annular reflectors of the game chips in the stack.
