DEFINITION

Classification: 400/156.1

Via mechanically permutated bar(s), disc(s), or plate(s):

(under subclass 154.1) Subject matter wherein said selecting mechanism includes one or more members, each member being either (a) an elongated component that is movable along its length, or (b) a circular component that is rotatable, or (c) a flat and relatively thin component that is movable in a plane parallel to its width and length dimensions, and also having particular index characteristics on the member, which member(s) is/are moved to a position relative to an arrangement within the mechanism where the index characteristics are aligned to enable movement of another component of the mechanism to effect selection or choice of the type-face* desired by the typist.
