Abstract
The reuse of an ink ribbon is prevented and the image quality and the proper paper feeding operation are secured by providing an ink ribbon damaging means to a ink ribbon cartridge of a color video printer. For example, a ring cutter is provided to the spool shaft of a spool on which an ink ribbon used for printing is wound so that the ink ribbon wound on the spool is cut.
