PROBLEM TO BE SOLVED: To securely communicate with even a wireless tag having a different wirelessly communicable range by wireless.SOLUTION: An image formation apparatus body 10 comprises: a plurality of antennas 20, 30 provided corresponding to a plurality of wireless tags 40, 50 differing in wirelessly communicable range; a read/write part 501; and a connection part (analog switches 60, 70 and 80) which determines a previously selected antenna as a selected antenna out of the plurality of antennas 20, 30 according to a wirelessly communicable range of a wireless tag (wireless tag 40 or wireless tag 50) fitted to a toner container 127 attached to the image formation apparatus body 10, and connects the selected antenna to the read/write part 501. The read/write part 501 uses the selected antenna connected to the read/write part 501 by the connection part so as to wirelessly communicate with the wireless tag (wireless tag 40 or wireless tag 50) fitted to the toner container 127 attached to the image formation apparatus body 10.SELECTED DRAWING: Figure 6 |
