ABSTRACT:
A color printing apparatus is provided with a document moving mechanism for reciprocatably moving a color document four times, and a scanner for applying successively white, red, green, and blue lights to the color document during each of the forward movements to produce image signals representative of complementary colors of the color lights. A drum with a paper wound therearound rotates forwardly and reversely in synchronism with the reciprocal movement. At the time of the forward movement of the document and the forward rotation of the drum, the thermal head presses a color ink ribbon against the paper to thermally transfer the ink of the color ink ribbon to the paper. At the time of the reverse rotation of the drum, the thermal head is separated from the drum by means of a solenoid.
