PURPOSE:To remove by discharing the frictional electricity generated due to the movement of an ink ribbon, reduce frictional resistance between an ink ribbon and a casing and suppress separation of an ink powder, by providing a conductive slip sheet between the casing and the ink ribbon. CONSTITUTION:To assemble the cartridge-type ink ribbon 33, flanges 22 of a spool 2 are inserted into spool-inserting holes 11 formed in main surface plates 36A of the casing 36, and then grooves 21 of the spool 2 are fitted to small pieces 13 of the plates 36A. In the assembly, the conductive slip sheet 5 with smooth surfaces is disposed between each of the plates 36A and the ribbon 3. With the slip sheets 5 thus provided, it is possible to prevent frictional electricity from being generated, or to remove by discharging the frictional electricity if it is generated, and to stably move the ink ribbon. |
