Abstract
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.

A radio tag communication device, comprising:
- 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;
- and
- a radio tag communication control unit 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.
A radio tag communication method, comprising:
- repeatedly transmitting an interrogation signal from a start time of an object conveyance until a reception strength of a response signal received from a radio tag on the object in response to the interrogation signal is equal to or greater than a predetermined threshold;
- and
- performing a writing on the radio tag once the reception strength of the received response signal is equal to or greater than a predetermined threshold.
An image forming apparatus, comprising:
- a sheet conveyance unit configured to convey a sheet for image formation;
- a printer unit configured to form an image on the sheet conveyed by the sheet conveyance unit;
- 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;
- and
- a radio tag communication control unit configured to cause the antenna to repeatedly transmit the interrogation signal from a start time of the sheet 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.
