ABSTRACT:
A radio-communication apparatus carries out movement of a dielectric element toward an antenna of RFID reader/writer when the RFID reader/writer cannot perform within a predetermined time radio-communication with a data carrier mounted on the RFID label that is arranged on a rolled base sheet passing between the dielectric element and the antenna. The movement is performed step by step to stop the dielectric element at positions at each of which the radio-communication is executed until the reader/writer can perform radio-communication with the data carrier within the predetermined time at any one of the positions.
