Abstract
A ribbon cartridge comprises a substantially cylindrical cartridge body comprised of upper and lower casing halves. A ribbon supply reel is rotatably housed in the cartridge body having an ink ribbon wound therearound. Affixed to a leading edge of the ink ribbon, a pull sheet is attached which includes an opening allowing easy chucking of the ribbon cartridge in a printer. Also provided on the pull sheet are cut-out portions so arranged as to prevent creasing of the ink ribbon during use. When the ink ribbon has been completely used, the used ribbon is retracted back into the cartridge for easy removal from the printer.
