Abstract
A ribbon cartridge for a serial printer includes a casing containing a supply reel, a take-up reel and a ribbon drive roller. A lower axial end of the drive roller is slotted to receive a drive shaft of a ribbon advance motor on the serial printer. The upper axial end of the drive roller is connected by a tension band to the upper end of the take-up reel shaft. The cartridge may be inverted by removing the tension band from the shafts of the drive roller and take-up reel, inverting the cartridge, and replacing the tension band on the shaft of the other reel and the shaft of a drive roller associated with the second reel.
