摘要：
An improved drive mechanism for an ink ribbon cassette for advancing an ink ribbon particularly well suited for use in a typewriter is provided. The drive mechanism includes a drive roller rotatably supported in the casing with a free floating pressure ring supported by a roller. The pressure ring is supported against the roller and against the drive roller so that there is an increase in pressure with an increase in the tension of the ribbon.
