Abstract (en)
The ribbon (20) is impelled to a point of use by a capstan (70) in frictional engagement with the ribbon. A resilient foam pad (95) is provided for urging the ribbon into frictional engagement with a frictional surface on the capstan. As a result, in operation the motion of the ribbon is damped by the force exerted on it by the foam pad. Any additional ink which has accumulated on the ribbon, as well as any contamination, is wiped off by the disposition of the inked surface of the ribbon in contact with the pad. The pad provides a damping mechanism so that when the capstan is moved incrementally by a stepping motor, the ribbon moves no further than is necessary and so is not wasted.
