ABSTRACT:
A protective pack for holding a cartridge for a daisy wheel type printer is disclosed. The cartridge has a supply spool for holding a fresh ribbon pancake and a take-up spool for holding used ribbon. The cartridge body has a viewport extending radially adjacent the ribbon pancake to allow observation thereof. The cartridge includes two arms which define a path for the ribbon to pass between the paper and the printer mechanism. Two drive gears are serially engaged with each other and with the ribbon drive means. When the first drive wheel is driven by a drive shaft of the printer, the second acts as an idler gear so that the direction of ribbon take-up is the same as the direction of the rotation of the drive shaft. When the second gear is driven, it drives the ribbon drive gear means directly so that the rotational direction of the ribbon take-up is opposite that of the drive shaft. The drive gears are located and their lower portions are configured to engage the respective drive shafts of various printers. The ribbon pack is an open shell having a cavity shaped to conform to the cartridge body. A shoulder projecting upward in the cavity inserts into the viewport when the cartridge is placed therein to prevent the ribbon pancake from telescoping during shipment.
