ABSTRACT:
An ink ribbon cartridge for a printing apparatus, in which two reels for the supply and take-up of a ink ribbon are rotatably mounted, incorporates a cartridge body and cover in which support sections for retaining the ends of the reels are provided. At an end of the cartridge, leaf springs are included which apply a constant frictional force to the reel hubs to prevent unwanted rotation of the reels. Therefore unwanted slackening of the ribbon is prevented, whether or not the printing apparatus is engaged in a printing operation.
