  • Code data writing-once apparatus for recording writing-once code data in unrecorded writing-once blocks of optically readably printed and recorded code data
    Patent number: 5768402
    Abstract: In a code data edit apparatus, dot code data read by an optical read unit is input to a processing function unit. In the processing function unit, the dot code data is decoded, and the processing result is displayed on a screen display unit. Upon reception of an instruction and data from a change input unit, the dot code data is edited in the processing function unit, and this process is displayed on the screen display unit in real time. The edit result is output by an edit output unit. In a dot code data writing-once apparatus, a data information determination unit is connected to the output stage of a dot code data read unit through a decoding unit. A display unit is connected to the output stage of the data information determination unit. The data information determination unit is connected to the output stage of a data input unit for inputting writing-once data.
