<p>PROBLEM TO BE SOLVED: To easily find out required baggage from piled up baggage. SOLUTION: An IC tag 10 is stuck to a baggage label, etc. In the IC tag 10, a sounding body 22 and an RF circuit 24 for radio communication are connected to an IC 20 consisting of a microprocessor 12, a mask ROM 14, an EEPROM 16 and an RAM 18. An antenna 26 is connected to the RF circuit 24. For instance, the operation program and the fixed information of the microprocessor 12 are stored in the mask ROM 14, and the data, etc., to be revised at need are stored in the EEPROM 16. A deliverer calls out the IC tag 10 stuck to the baggage by a calling radio equipment when the baggage to be taken out exists. This radio signal is received by the antenna 26 and the RF circuit 24 to be transferred to the microprocessor 12. The microprocessor 12 judges whether or not a call shows itself, and when it shows itself, the microprocessor 12 makes the sounding body 22 generate an acoustic signal for a prescribed time.</p> |
