ABSTRACT:
The elements of a drive assembly for punched paper tape are arranged in a fixed relation on a shaft (42) to which the paper feed wheel (70) is attached. The assembly includes a drive mechanism (25 or 27) for selectively imparting equal increments of rotational motion to the shaft, first and second ball bearing assemblies (65, 75), spacers (74, 68, 69) and a nut (76). The shaft assembly is slidable within holes in the frame sideplates (71, 73) and within curved surfaces of projections (66, 67) of the paper guide body (28).
