摘要： A constant tension device for peeling an ink ribbon away from a printing medium during a correction operation in which ink printing produced by a thermal transfer printer is erased, a roller mounted on the printer is pressed against another roller mounted on a ribbon cassette, an ink ribbon is trained over the roller mounted on the ribbon cassette and between the two rollers, and the ink ribbon is stretched by the rotation of the roller mounted on the ribbon cassette which is rotated with a constant speed so as to provide a constant tension so that the ribbon is reliably peeled away from the printing medium.
