Abstract
Writing incorrect information to an IC tag affixed to a medium is prevented. When a control command including recording information, an instruction to record the recording information on a medium, and an instruction to write data including at least time-related information to an IC tag affixed to the medium is received from a host computer, the system controller 35 of a media processing device 2 records the recording information and writes the write data based on time information input from a RTC 29, but does not record the recording information and write the write data based on the control command if a RTC 29 error was detected by a RTC error detection unit 36b.
Claims15
A media processing device that can connect to a control device, the media processing device comprising:
- a real-time clock that keeps time;
- an error detection unit that detects a real-time clock error;
- a data writing unit that writes specific information by wireless communication to an IC tag embedded in media;
- and
- a control unit that
- controls the data writing unit,
- checks the error detection unit when identification information is received from the control device,
- acquires time information from the real-time clock,
- causes the data writing unit to write the time information and identification information to the IC tag if the error detection unit did not detect a real-time clock error, and
- causes the data writing unit to prohibit the writing of the time information and identification information to the IC tag if the error detection unit detected a real-time clock error.
A control method for a media processing device that can connect to a control device and includes a real-time clock that keeps time, an error detection unit that detects a real-time clock error, and a data writing unit that writes specific information by wireless communication to an IC tag embedded in media, the control method comprising:
- checking the error detection unit when identification information is received from the control device;
- acquiring time information from the real-time clock,
- writing the time information and identification information to the IC tag using the data writing unit if the error detection unit did not detect a real-time clock error;
- and
- prohibiting the writing of the time information and identification information to the IC tag if the error detection unit detected a real-time clock error.
A non-transitory storage medium that stores a program for execution by a control unit that controls parts of a media processing device that can connect to a control device and includes a real-time clock that keeps time, an error detection unit that detects a real-time clock error, and a data writing unit that writes specific information by wireless communication to an IC tag embedded in media, the program causing the control unit to:
- check the error detection unit when identification information is received from the control device;
- acquire time information from the real-time clock;
- cause the data writing unit to write the time information and identification information to the IC tag if the error detection unit did not detect a real-time clock error;
- and
- cause the data writing unit to prohibit the writing of the time information and identification information to the IC tag if the error detection unit detected a real-time clock error.
