Abstract
A ribbon cartridge with an ink ribbon for use in a printer. The printer includes a print head and a carrier, the carrier carrying the print head and ribbon cartridge along a printing position. The carrier has a mounting member for rotatably mounting a first end of the ribbon cartridge and a guide member for positioning a second end of the ribbon cartridge such that the ink ribbon is disposed between the print head and printing position. The second end of the ribbon cartridge has an opening for exposing a part of the ink ribbon loaded in the body of the cartridge. The ribbon cartridge includes a biasing member for producing a force to bias the ribbon cartridge against the guide member by elastic deformation of the biasing member in contact with a part of the carrier. The biasing member is integrally formed as part of the ribbon cartridge, thus eliminating additional and separate components and reducing part and assembling costs. Limitation members are also integrally formed as part of the ribbon cartridge to restrict maximum pivotal movement of the second end of the ribbon cartridge when mounted to the carrier, thus ensuring that the biasing member of the cartridge is not deformed beyond its normal elasticity.
