Abstract: A ribbon cartridge comprising a housing, a supply reel containing a supply of ribbon wound thereon, a take-up reel, means for rotatably mounting the supply reel at a first location in the housing, means for rotatably mounting the take-up reel at a second location in the housing, the second location being spaced both vertically and horizontally from the first location, and means for transferring ribbon along a predetermined path from the supply reel onto the take-up reel.

Abstract: Apparatus for generating a velocity command signal representing a predetermined optimum velocity of movement of a selected one of a plurality of movable elements from its actual position to a desired stopping position. The apparatus comprises means responsive to a first signal representative of the distance to be traveled by the selected movable element from its actual position to a desired stopping position for generating a second signal proportional to a predetermined optimum velocity of movement for each of the plurality of movable elements when required to be moved a distance represented by the first signal.
