Abstract

When writing information to the IC tag of a medium, the control unit 54 of a printer 1 determines if a specific area in the storage space of the IC tag is in an initialized state, and writes to the IC tag if the IC tag is in the specific state.

Claims

1. -15. (canceled)

16. A media processing device comprising:

a data read/write unit configured to read information stored in an IC tag and to write information to the IC tag, the IC tag being disposed on a media; and

a controller configured to control the data read/write unit to detects the IC tag that can communicate;

wherein, when the controller determines that plural IC tags are detected, the controller prevents the data read/write unit from writing information to the plural IC tags.

17. The media processing device described in claim 16,

wherein, when the controller determines that the number of detected IC tags is 1, the controller acquires memory data from the IC tag and determines whether writing information to the IC tag is permitted based on the acquired memory data.

18. The media processing device described in claim 16,

wherein, in detecting the IC tag that can communicate, the controller controls the read/write unit to send a detection signal and determines the number of detected IC tags based on receipt of a response signal to the detection signal.

19. The media processing device described in claim 16, further comprising:

a conveyance roller configured to convey the media in a conveyance path, the media having a plurality of IC tags disposed thereon,

wherein the read/write unit outputs a carrier wave, the carrier wave having directivity toward a specific area of the conveyance path.

20. A printer comprising:

a data read/write unit configured to read information stored in an IC tag and to write information to the IC tag, the IC tag being disposed on a media;

a controller configured to controls the data read/write unit to detects the IC tag that can communicate; and

a print head configured to print the media, the media including the IC tag to which information has been written,

wherein, when the controller determines that plural IC tags are detected, the controller prevents the data read/write unit from writing information to the plural IC tags.

21. The printer described in claim 20,

wherein, when the controller determines that the number of detected IC tags is 1, the controller acquires memory data from the IC tag and determines whether writing information to the IC tag is permitted based on the acquired memory data.

22. The printer described in claim 20,

wherein, in detecting the IC tag that can communicate, the controller controls the read/write unit to send a detection signal and determines the number of detected IC tags based on receipt of a response signal to the detection signal.

23. The printer described in claim 20, further comprising:

a conveyance roller configured to convey the media in a conveyance path, the media having a plurality of IC tags disposed thereon,

wherein the read/write unit outputs carrier wave, the carrier wave having directivity toward a specific area of the conveyance path.

24. The printer described in claim 23, wherein:

the specific area is upstream from a printing position in the conveyance path, the printing position being on which the media is printed by the print head.

25. A control method of a media processing device including a data read/write unit configured to read information stored in an IC tag and to write information to the IC tag, the IC tag being disposed on a media, the method comprising:

detecting the IC tag that can communicate; and

,

when the plural IC tags are detected, preventing the data read/write unit from writing information to the plural IC tags.

26. The control method described in claim 25, further comprising:

acquiring memory data from the IC tag when the number of detected IC tags is 1, and

determining whether writing information to the IC tag is capable or not based on the acquired memory data.

27. The control method described in claim 25,

wherein detecting the IC tag that can communicate includes

sending a detection signal by the read/write unit, and

determining the number of detected IC tags based on receipt of a response signal to the detection signal.

28. The control method described in claim 28, further comprising

conveying the media in a conveyance path, the media being on which a plurality of IC tags disposed;

and

controlling the read/write unit to output carrier wave, the carrier wave having directivity toward a specific area of the conveyance path.
