Endless ink ribbon cassette having selective ribbon tension control |
摘要 |
An ink ribbon cassette for a printer includes a ribbon storage chamber in which an endless ink ribbon is stored. The ribbon has a portion lying outside the chamber, and is movable out of and into the chamber by a feed roller. A roller is provided in the vicinity of the ribbon outlet of the chamber. A spring is provided adjacent to the chamber for holding the ribbon against the roller to impart tension to the outwardly lying ribbon portion. A lever contacts the spring, and is rotatable to deform the spring so that the spring may hold the ribbon against the roller with an increased force.
