<P>PROBLEM TO BE SOLVED: To execute an access to a wireless tag circuit element being an access object with a transmission output as small as possible. <P>SOLUTION: The wireless tag information communication apparatus includes a cartridge 20 configured to accommodate a plurality of wireless tag circuit elements 10A and to be able to sequentially extract them and an antenna 40 for making transmission / reception of data with an antenna 101 of the sequentially extracted wireless tag circuit element 10A through wireless communication, a signal processing circuit 52 generates first access information used for accessing wireless tag information of an IC circuit section 100, a transmission section 53 transmits the generated first access information to access the wireless tag information of the IC circuit section 100, after execution of the access, a control circuit discriminates whether or not the access is successful, and controls the magnitude of a transmission output from the transmission section 53 in response to a result of the discrimination. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
