Printer and ribbon roll

Abstract

A ribbon roll held by a ribbon holder comprises a cylindrical member, an ink ribbon wound around the cylindrical member and a data holding section which is arranged on surface of the cylindrical member and has plural areas where identification codes indicating information relating to the ink ribbon are recorded A driver rotates the cylindrical member held by the ribbon holding section. A detector detects components of the identification code and the mark from a position facing the data holding section of the ribbon roll held by the ribbon holder. A rotation controller enables the driver to rotate the cylindrical member to an extent to which the detector can detect the identification code. A reading controller carries out reading of the identification code by taking the mark as a reference from the components detected by the detector in synchronization with the rotation by the rotation controller.
