RIBBON CARTRIDGE FOR LABEL PRINTING DEVICE

The present invention relates to a ribbon cassette for a label printing device comprising a ribbon cassette case that contains a printing tape (18) for printing, a medium tape (17) for providing printing medium, and a carrier tape (20) used as carrier. The label printing device is provided with a determining region (5) for determining feature information of the ribbon cassette, the determining region is provided with a plurality of determining columns (XY) with planar distribution. The ribbon cassette further comprises a detecting portion (10) corresponding to the determining region of the label printing device, the detecting portion is detecting column(s) (11) corresponding to the determining columns. The number or position of the detecting column characterizes the feature of the ribbon cassette, or a combination of the number and the position of the detecting column characterizes the features of the ribbon cassette. Since the manner that the detecting column is against the corresponding determining column is adopted to make the label printing device can perform detection, which significantly improves accuracy of detection of feature information of the ribbon cassette, compared with a combination of pore and non-pore portions adopted in the detecting portion.
