PURPOSE:To print a reversed letter by a method wherein letters and signs are printed on a medium such as a paper tape or the like with an one-time ribbon and the shape of the letters are punched out, thereafter, are printed on a printing paper with a whole black type body. CONSTITUTION:When a signal of a reversed printing is received, a magnet 13 is excited simultaneously and a tape base 10 is attracted. According to this operation, a paper tape 8 is inserted and set between an one-time carbon ribbon 1 and a printing paper 4. When a type of an enphasized letter is printed selectively under this condition, carbon corresponding to the letter on the ink ribbon 1 is disappeared wholly. Thereafter, the paper tape 8 is returned to an original position and a constant amount thereof is wound up by a motor 14. On the other hand, the ink ribbon 1 is not moved and a whole black type 16 is selected to print in a superposed condition, therefore, the reversed letter is formed on the printing paper 4. |
