Abstract
A thermal transfer printer which can simply and assuredly erase a symbol recorded in error with thermal transfer ink on record paper. The printer comprises, in addition to a printing transfer ribbon and a printing thermal head, an erasing ribbon carrying thereon a layer of a thermally adhesive resin material, and an erasing thermal head which is operated, during erasing operation, to generate heat to melt the thermally adhesive resin on said erasing ribbon sufficient to adhere to the thermally fusible ink of a symbol printed on record paper so that the ink may be removed from the paper as the erasing ribbon is moved away from the record paper. The printing and erasing thermal heads are mounted in a juxtaposed relationship on a movable carriage, and the erasing thermal head has a greater heat generating area than the printing thermal head.
