Patent application number | Description | Published |
20080231420 | DATA READER AND POSITIONING SYSTEM - A data reader can read data regardless of the position of a radio IC tag. The data reader reads data at a separate position from a radio IC tag provided with a storage unit storing data and a communicating antenna for transmitting the data stored in the storage unit, and includes a reader/writer for generating a modulated signal by modulating a carrier wave and a plurality of antenna units for transmitting radio waves for a read for communicating data with a storage medium by radiating the modulated signal into the air. The reader/writer includes a phase adjustment circuit for changing the phase of a carrier wave. | 09-25-2008 |

20090102614 | Wireless Communication Tag and Wireless Communication System - A wireless communication tag according to the present invention includes a first antenna | 04-23-2009 |
20090104981 | Game Chip, Game Chip Writer/Reader, and Game Chip Monitoring System - A game chip writer for writing at least identification information in a game chip used for a game includes an encryption unit for encrypting at least part of recording-information with use of a private key and a writing unit for writing the encrypted information. A game chip reader includes a reading unit for reading the encrypted information from the game chip and a decryption unit for decrypting the read information with use of a public key. | 04-23-2009 |
20100210355 | GAMING SYSTEM - A gaming system is provided enabling real-time cash management to be performed, even while in the play of a game to be performed by employing game media rendering their items of recorded information readable. Having received a result of detection of game chips on a game betting board from a game betting device, a server device accumulates the result of the detection, and judges whether or not movement of game chips has occurred between a dealer and each player, in comparison with a past result. When movement of game chips has occurred between the dealer and such each player, data relevant to a game chip table, a player table, and a dealer table is updated so as to reflect a result of the movement. | 08-19-2010 |
20130087613 | IDENTIFICATION INFORMATION ACCESS DEVICE - The present invention provides an identification information access device configured to read identification information stored in an RFID tag even if the RFID tag is located at a position at which identification information of the RFID tag has been difficult to read. An identification information access device includes: a first antenna unit configured to read identification information stored in an RFID IC tag included in a storage medium; a control device configured to be electrically connected to the first antenna unit and to drive the first antenna unit so as to acquire the identification information in accordance with an electromagnetic wave transmitted from the first antenna unit; and a second antenna unit configured to be independent from the first antenna unit, to be disposed at a position separated from the first antenna unit, and not to be electrically connected to the first antenna unit and to the control device. | 04-11-2013 |
20130270342 | IDENTIFYING INFORMATION ACCESS DEVICE - It is possible to read from and write in an RFID tag, and also to operate other devices. A non-contact control device is provided which is formed to have no electrical contact with the electromagnetic wave generating antenna part and integrally with the electromagnetic wave generating antenna part. The non-contact control device receives an electromagnetic wave generated by the electromagnetic wave generating antenna part to generate electric power, and controls a controlled device based on the generated electric power. | 10-17-2013 |
20140291399 | TOKEN STORAGE DEVICE - Provided is a chip tray which is capable of accurately reading out an IC tag for use in RFID without increasing a magnitude of a magnetic field generated by an antenna. A magnetic field generating antenna is disposed along a direction in which a plurality of tokens having embedded therein feeder antennas of IC tags for use in RFID are stacked. | 10-02-2014 |
