  • Patent number: 4668961
    Abstract: A recording apparatus includes supply and take-up reels stored in a cassette case, a print head and a carriage. An ink ribbon housed in the cassette case can be fed from the supply reel in both the forward and reverse directions guided by means of guide rollers. The print head can be movable along print paper in a direction perpendicular to the forward and reverse directions so as to press portions of the ink ribbon fed in the forward and reverse directions against the print paper so as to perform printing. The print head and the cassette case are mounted on the carriage. Thus, since printing can be performed by driving the supply reel in a single direction, a ribbon driving system can be simplified, resulting in low cost.
