PURPOSE:To control static electricity generated by the increase in a thermal transfer speed and the widening of an ink ribbon, by providing cartridge sheets each comprising a thin conductive material contacted with the upper and under surfaces of a pan cake and a means for falling said cartridge sheet to the ground of a printer. CONSTITUTION:A cartridge sheet 2 comprises a conductive film and two cartridge sheets 2 are adhered to the upper and under surfaces of a cartridge 1 and contacted with pan cakes 5 comprising an ink ribbon 4 at the upper and under surfaces thereof while take a continuity state through a FG spring 6 and is earthed to the ground 8 through a cartridge guide 7 when the cartridge 1 is mounted. The static electricity charged to the ink ribbon 4 during printing is earthed to the ground 8 of a printer from the pan cakes 5 through the cartridge sheets 2 when a thermal head 9 rubbs the back surface of the ink ribbon 4 or the ink ribbon 4 is released from printing paper 9 and the generated static electricity is suppressed to 2kV or less. |
