DEFINITION

Classification: 400/70

INCLUDING SELECTION OF TYPE-FACE BY PROGRAMMED-CONTROL-SYSTEM OR BY REMOTE CONTROL:

(under the class definition) Subject matter wherein a programmed-control-system or a signal from outside of a typewriter governs the operation of the typewriter so as to impress selected or chosen type-face* elements against the record-medium* to imprint character* symbols successively.

(1) Note. In the typewriter of this and indented subclasses the programmed-control-system is used to select or choose the type-face elements that are to imprint the characters in sequence. The difference between "select" and "choose" as to the type-face element is discussed in the glossary, section III, under definitions such as case-shift*, type-face-carrier*, type-head*, and type-head-carrier*. Briefly, A particular type-face is selected from among the many available from a type-set-assemblage*, whereas an upper-case* form of letter (As distinguished from a lower-case* form of the same letter) is chosen from the forms of that letter available on one key* element.

(2) Note. The signal from outside the typewriter that governs the operation of the typewriter is usually referred to in such functional terms as "reader", "translator", "storage", "input", etc. it is not a remote signal such as that transmitted by a printing telegraph of Class 178. See (1) note to Class 178, Telegraphy, in section IV of the class definition of this class (400), for the distinction between this class (400) and Class 178, Telegraphy.
