Abstract
PURPOSE:To accurately protrude the leading end of each color ink layer, by intermediately providing a film having a coefficient of friction not lower than those of ink layers between a base and the ink layers and markers. CONSTITUTION:A color ink ribbon 1 comprises, on a base 2, a film 5 having a coefficient of friction not lower than those of ink layers 3, the film 5 being colorless and transparent so that it is not detected by a sensor 10. A plurality of color ink layers 3A, 3B, 3C... are provided in a laminate form on the film 5 at intervals, and markers 4 different in length are provided on the base 2 at positions spaced from each of the ink layers 3. When color printing is conducted, the film 5 instead of the base 2 makes contact with a paper 20, and since the coefficient of friction of the film 5 is not lower than those of the ink layers 3, the color ink ribbon 1 is fed at a constantly fixed velocity without generating any relative velocity between the ribbon 1 and the paper 20. Since the film 5 is colorless and transparent, it does not hinder the passage of light which is to travel from a light emitter 23 to a light receiver 24, and the sensor 10 accurately discriminates the colors of the ink layers 3 by the markers 4. Accordingly, an operation of protruding the leading end of each of the ink layers 3 can be carried out accurately, and color printing with favorable quality can be performed.
