摘要:
PROBLEM TO BE SOLVED: To provide a radio tag detecting system for detecting a radio tag suitably in a prescribed region while the interference of each transmission electric wave is prevented adequately. SOLUTION: A transmission control unit 146 for carrying out control so that a plurality of fixing type radio tag communication devices 12 and a portable type radio tag communication device 14 transmit their transmission signals with different timing is provided. By transmitting the transmission signal in time sharing, interference between transmission waves from the plurality of fixing type radio tag communication devices 12 and from the portable type radio tag communication device 14 is prevented suitably. Namely, while the mutual interference of the transmission wave is prevented suitably, the radio tag detecting system 10 for detecting the radio tag 16 in the prescribed region adequately can be obtained.
