Patent number: 7548213Abstract: 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.Type: GrantFiled: December 15, 2005Date of Patent: June 16, 2009Assignees: Aruze Corp., Seta Corp., Minerva Corp.Inventors: Toshimi Koyama, Nobuyuki Nonaka, Jituo Migita

Publication number: 20060154731Abstract: A game chip transmits information in response to an inquiry from a reader/writer. The game chip comprises an IC device, an antenna coil unit, a first ring and a second ring. The IC device constitutes an electromagnetic induction coupling circuit with the reader/writer and stores information. The antenna coil unit is connected to the IC device and generates an induced current by a magnetic flux emitted from the reader/writer to supply power to the IC device when the inquiry is received. The first ring induces the magnetic flux emitted from the reader/writer in one of directions of moving away from and approaching the reader/writer. The second ring induces the magnetic flux induced by the first ring in the other of the directions of moving away from and approaching the reader/writer.Type: ApplicationFiled: December 13, 2005Publication date: July 13, 2006Applicants: Aruze Corp., Seta Corp., MINERVA Corp.Inventors: Toshimi Koyama, Nobuyuki Nonaka, Jituo Migita
