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.

Abstract: Apparatus for feeding ribbon in an impact printer or typewriter is provided in which the ribbon metering means are very simple and minimize the potential for damage to the ribbon. Ribbon is fed from a supply reel (12) to a take-up reel (16) each of which is adapted to support a portion of an inventory of ribbon running from the supply reel to the take-up reel. The apparatus includes a drive mechanism (20) which drives the take-up reel at a selected one of a plurality of different rotational velocities, apparatus for sensing the portion of the inventory of ribbon on one of the reels and for producing an electrical signal representative of the radius of said portion, and apparatus for selecting one of said rotational velocities in response to said signal. More particularly, the sensing means which sense the portion of the ribbon inventory remaining on the supply reel and the sensing means are preferably capacitive sensing means (21, 26).

Abstract: A REVERSIBLE RIBBON CARTRIDGE FOR A HIGH SPEED IMPACT PRINTER 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: The present invention resides in an improved apparatus and method for replenishing the ribbon supply in a high speed printer or the like. A stationary ribbon supply is provided in a two reel, cartridge (2). Connected to the printer frame adjacent the stationery cartridge on either side is a flexible ribbon guide (6) for maintaining the ribbon in operative relation to a print element (10) on a moving carrier (12). … When the ribbon supply is exhausted, the specially designed ribbon segments extending from the cartridge are severed. The flexible ribbon guide (6) still contains a segment of the old ribbon in the properly threaded position for printing. The old cartridge is removed. A new cartridge with ribbon leaders having adhesive portions for splicing with the old ribbon segment remaining in the flexible guide structure is inserted. The operator then manually performs adjustments required to resume printing.

Abstract: PAPER GUIDE MEANS FOR REVERSE FEED SHEET PAPER SEPARATION DEVICE Mechanism for separating the uppermost pliant sheet of a stack of such sheets from the stack including a rotatable friction drive wheel effective on the longitudinal center line of the uppermost sheet for initially moving the sheet rearwardly, and a pair of downwardly tapered posts at the rear face of the stack and on opposite sides of the center line which cause the uppermost sheet to bow upwardly away from the stack particularly on its side edges for thereby effectively separating the sheet from the stack and allowing it to be driven subsequently in the forward direction to free it completely from the stack.
