DEFINITION

Classification: 400/154.3

By shortest peripheral path:

(under subclass 154.1) Subject matter wherein the typewriter is provided with a type-head* having a cylindroidal or spheroidal surface having the type-face* elements of a type-set-assemblage* thereon, which type-head is normally in a particular rest position and is moved to a second position at which the selected or chosen type-face will be impressed against the record-medium*, and wherein significance is attributed to movement of the type-head that results in the least amount of type-head movement as it moves from the rest position to the second position.
