PURPOSE:To make it possible to make easy to print a high throughout multicolor printing and to prevent a production of a dirty printing by providing an inking roller supplying a prescribed color ink on a printing negative plate on which a printing hole is formed. CONSTITUTION:Printing holes which permit a passing through of an ink by an impact of a dot wire are formed on the ribbon 6 between the medium 3 and the print head 1. Three inking rollers 7 (71, 72) which can supply a prescribed color ink to the ribbon are provided on both sides of the print head 1 on the carrier 4, and the mechanism section 8 which sends out the roller 7 to contact to the ribbon 6 is also provided. The high throughout printing is made possible, since a selection of the printing color is carried out by contacting the rollers 71, 72 to the ribbon being displaced arbitrary and supplying the ink. It is easy to make into a multicolor by providing the like inking rollers 71, 72 on both sides of the head 1, the production of a dirty printing of the medium by the ribbon 2 is prevented, since the contact of the ink to the medium is limitted only to the holes on the ribbon 6 which permit a passing through of the ink. |
