Abstract
A ribbon cartridge includes a feed core and a takeup core around which an ink ribbon is wound. The cartridge is formed substantially symmetrically in the right-left direction and reversibly loaded in a printer. The ribbon whose width is great enough to accommodate two characters has a upper and a lower parts which each extend in the lengthwise direction of the ribbon, the upper and lower parts being usable in sequence for printing out data. A ribbon feed belt is passed over a drive roller and a pair of rollers which are located to define apexes of a triangle, remaining in frictional contact with the outer peripheries of the ribbon on the opposite cores. The drive roller drives the belt to feed the ribbon. A color ink ribbon which may be installed in the cartridge has an upper portion in which different colors are provided in a repetitive pattern in a predetermined order and a lower portion in which they are provided in a predetermined order opposite to that of the upper part, the colors appearing in the same order at a print position even when the cartridge is turned upside down.
