摘要：
According to one embodiment, a radio tag communication device includes an antenna configured to transmit an interrogation signal and receive a response signal from a radio tag transmitting the response signal in response to the interrogation signal. A radio tag communication control unit of the device is configured to cause the antenna to repeatedly transmit the interrogation signal from a start time of an object conveyance until a reception strength of the response signal received by the antenna is equal to or greater than a predetermined threshold, and then perform writing on the radio tag via the antenna once the reception strength of the response signal received by the antenna is equal to or greater than the predetermined threshold.
