摘要： A fabric ribbon (13) is stuffed in a cartridge chamber (11). Two pinch rollers (35 and 39) are driven by a third roller (29). The direction for forces from the pinch rollers is toward a wall portion (9a), which is near an opening having a dam (ridge 67) which leads to chamber (74) have an exit slot (71) located near the wall portion (9a). The drive roller (29) is positioned to be located where the drive roller of an existing cartridge was located, making this cartridge interchangeable with a cartridge for a spool-to-spool ribbon.
