PROBLEM TO BE SOLVED: To enable a communication between an information receiving device and respective noncontact type carrier labels even when the noncontact type data carrier labels are closely arranged by providing objects to be managed with respective noncontact type data carrier means without cutting off the communication between the noncontact type data carrier means and information receiving device. SOLUTION: For the objects 1, 1a to 1e, noncontact type data carrier labels 2, 2a to 2e are arranged so that communication paths 5a to 5e to an information transmitting and receiving device 3 do not overlap. The noncontact type data carrier labels 2a to 2e store data showing IDs for identifying the objects 1a to 1e to be managed, information on their contents, etc. Then data that the respective noncontact type data carrier labels 2a to 2e have are sent to the information transmitting and receiving device 3, information, etc., showing processing stages is received from the information transmitting and receiving device 3, and the data from the information receiving device 3 are stored in the noncontact type data carrier labels 2a to 2e to manage a history of distribution processing stages of the objects to be managed. |
