DEFINITION

Classification: 400/518.3

With means to imprint selectively on one or more media (e.g., by holding selected media away from print-line):

(under subclass 518) Subject matter wherein a typewriter normally is used to type an original copy and several carbon copies simultaneously, and wherein a typist is enabled to type one or more character* symbols on one or more of the copies without typing those character symbols on the other copies.

(1) Note. Usually the original copy and/or one or more of the carbon copies that is/are not to be imprinted are moved to a position away from the print-point* so that a type-face* will not impact there-against. An alternative structure to perform this operation is the provision of a second platen* member positioned to shield some of the copies and enable imprinting on the other copies.
