Abstract
The type carrying disc has the type characters spaced irregularly along the disc periphery in dependence on their width, but the order in which these characters appear on the disc is independent of their width. Associated on the disc with each type character is an aperture that indicates the angular position of the corresponding type character. A photoelectric detector reads these apertures as the disc spins, and enables, in dependence on a coded signal, the disc to be stopped at the correct position for printing the desired character. In other embodiments, the aperture or other means indicates one or another printing characteristic, such as printing force or size of the printing step.
