Abstract
An improved mechanism for incrementing characters in a printing device, generally applicable to the field of endorsers. An endless character belt has printing characters on its outer surface, the character belt designed to be incremented to present varied characters. The belt is moved by means of a sprocket wheel having gear teeth. A rod with an upstanding pin engages the sprocket wheel of the character belt to be incremented. By stacking several character belts adjacent to each other, each having its own sprocket wheel, the belts can be incremented separately and apart from each other.
