Abstract: A tag reading device can effectively read a plurality of tags. The tag reading device includes a power control unit (109) for controlling an output power of a transmission unit (101) by a control signal so as to transmit transmission data with an output power set by an output power setting unit (108). When a plenty of tags exist in a readable area and identifiers of the gags frequently make collisions, firstly, the output power of the transmission unit (101) is reduced so as to narrow the readable area and suppress generation of collisions. When the number of tags existing in the readable area of a reader (100) and not yet read has become small, the output power of the transmission unit (101) during retransmission is increased and the readable area of the reader (100) is increased and the remaining tags are effectively read.
