PURPOSE:To prevent the generation of printing inferiority such as ghost, by changing the angle of inclination of each type at a rising part from each spoke part corresponding to the distance from the center of a type wheel. CONSTITUTION:An umlaut in a type 4a in the upper side of a base line BL is provided on the type side pedestal 4b provided to the leading end of a spork 3 and presses the printing paper 9 mounted to a platen 8 through an ink sibbon 7 in a state sunk by a printing hammer 6. In this type 4a, because the angle theta(about 30 deg.C) of the type 4a at the rising part from the pedestal 4b of said type 4a is large, the force F2 acting on a C-range is not extremely smaller than the force F acting on a D-range and, therefore, almost uniform transfer force is generated between the ink ribbon 7 and the printing paper 9 over the entire surface of a transfer range and no ghost is generated. |
