    Abstract: In a high speed impact printer having means for receiving a ribbon cartridge and for driving the ribbon in said cartridge, the improved apparatus comprising a ribbon cartridge to be inserted in said receiving means and adapted to be reversed one time only which comprises a cartridge housing with first and second reels rotatably mounted in said housing; each of the reels is adapted to support a portion of inventory of a ribbon web which is being driven from one reel to the other reel by the impact printer means for driving said ribbon. A keyed tenon projects from said housing and has an initial position and a second position; the keyed tenon is switchable from the initial position to the second position but irreversible from said second position. The receiving means in the printer includes means for exclusively receiving the tenon keyed in its initial position wherein the ribbon is driven from the first reel to the second reel and means for exclusively receiving the keyed tenon in its second position wherein ribbon is driven from the second reel to the first reel.

    Abstract: In an impact printer with a conventional combination of platen and cardholder wherein the cardholder has an inner surface with a curvature matching that of the platen and is mounted adjacent to but spaced from the platen so that a sheet of printing medium may be moved between the cardholder and platen and wherein conventional impact printing is carried out by impact means acting upon the sheet through an opening in the cardholder, an improved cardholder structure is provided wherein the cardholder comprises integral ribbon guide means for guiding the printer ribbon in a path along the outer surface of the cardholder across the opening whereby the impact means may selectively drive the ribbon through the opening to print upon the sheet. In accordance with another aspect of the present invention, the cardholder further comprises integral end of ribbon sensing means mounted in a fixed position along said ribbon path.

    Abstract: In a high speed printer, apparatus is provided for rotatably driving a ribbon take-up reel and a ribbon supply reel, each reel being adapted to support a portion of an inventory of ribbon running from the supply reel to the take-up reel at a constant speed differential between reels. This apparatus comprises a first inelastic drive belt for peripherally non-slip driving the ribbon portion on the take-up reel and a second inelastic drive belt unattached to the first drive belt for peripherally non-slip driving the ribbon portion on the supply reel. Means are provided for driving the first belt at a constant selected speed and drive coupling means provided which are non-slip driven by the first belt and are for non-slip driving the second belt at a constant speed which is slower than the first belt. In this manner, the web or ribbon between the supply reel and the take-up reel is maintained under a constant uniform strain level.
