Patent ID: 7602295

Claim:
A radio-communication apparatus which carries out a data read/write operation to RFID labels peelably arranged on a base sheet, comprising: an antenna configured to perform transmission or reception of radio waves; a reader/writer configured to execute radio-communication with one of the RFID labels through the antenna to carry out the data read/write operation when the one of the RFID labels comes to a radio communicable area of the antenna; a dielectric element facing the antenna at a distance, the base sheet passing between the dielectric element and the antenna; a moving mechanism configured to regulate a relative distance between the dielectric element and the antenna if the reader/writer cannot execute radio-communication with the one of the RFID labels within a predetermined time; and a control section configured to control the operation of the moving mechanism to enable radio-communication between the reader/writer and the one of the RFID labels.
