Abstract (en)
[origin: US4655623A] An ink ribbon cassette for winding an ink ribbon from a feed spool to a winding spool is provided. The cassette includes a base with a guide path for receiving a guide projection formed on a support member having a feed spool sleeve. A drive roller and controlling roller are rotatably mounted on the cassette base. A winding spool is rotatably mounted on the feed spool sleeve and biased towards the drive roller, and a feed spool is rotatably mounted on the feed spool sleeve and biased towards the controlling roller. The spool sleeves are positioned so that when the guide projection of the support moves within the guide path the winding spool operatively engages the drive roller and the support member pivots about the guide projection so that when the ribbon is wound from the feed spool to the winding spool, the feed spool maintains engagement with the controlling roller.
