A first antenna section, a second antenna section, a transmitting signal generating section configured to generate a predetermined transmitting signal for a wireless tag, a transmitting section configured to transmit the transmitting signal generated by the transmitting signal generation section from the first antenna section, and a receiving section configured to receive a response signal from the wireless tag through the second antenna section. Furthermore, the invention is constituted to include an error detecting section configured to detect a predetermined error in the response signal sent from the wireless tag and received by the antenna section, and an antenna switching section configured to carry out switching for receiving the response signal sent from the tag through the first antenna section and transmitting the predetermined transmitting signal through the second antenna section based on a result of the detection obtained by the error detecting section. |
