ABSTRACT:
A printer includes a type wheel carrying a multiplicity of fingers each carrying types disposed in a plurality of tiers, and centrally formed with a rotary shaft. The type wheel is disposed perpendicular to the axis of a platen. The printer performs a printing operation by imparting to the type wheel a motion which selects one of the plurality of tiers and a rotary motion for selecting one of the multiplicity of fingers. A rotating drive from a drive shaft is transmitted to the rotary shaft of the type wheel through a joint comprising a pair of closely disposed or coplanar pins which are orthogonal to each other and a ring-shaped or forked coupling member having openings or grooves in which the respective pins are slidably fitted.
