<P>PROBLEM TO BE SOLVED: To restrain an increase in the number of transmission/reception devices relative to the number of radio-function-having memory modules incorporated in an apparatus. <P>SOLUTION: In a copying machine 10, a radio tag a (40), etc., are attached to a plurality of components. The radio tag a (40), etc., wirelessly communicate with an X transmission/reception terminal 30, Y transmission/reception terminal 32, and Z transmission/reception terminal 34, all of which are connected to a control section 20 with cables. Based upon the time needed for a response to a communication between each transmission/reception terminal and its corresponding radio tag, the identification data of each radio tag is obtained in advance. The identification module 22 of the control section 20 compares the identification data of each radio tag with an actual response to the communication between each transmission/reception terminal and the corresponding radio tag, thereby identifying and prescribing each of the radio tags. A data reading module 24 and a data writing module 26 read and write data between the prescribed radio tags. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
