.~.~ With prevention of ribbon feed (e.g., for nontype operation, etc.)
DEFINITION
Classification: 400/231
With prevention of ribbon feed (e.g., for nontype operation, etc.):
(under subclass 223) Subject matter wherein there is a drive mechanism for moving the ribbon* relative to the
print-point*, and wherein significance is attributed to stopping or disconnecting such drive mechanism while a function* is performed on the typewriter.
(1) Note. It is usual to have ribbon movement depend on carriage* movement as the carriage is moved in the direction of the print-line* while character* symbols are imprinted so that a fresh ribbon surface is presented for each type-face* impact. There are other carriage movements (e.g., for spacing between words, backspace, etc.) where no imprint takes place and so a fresh ribbon surface is not needed as a result of the latter movements. This subclass (231) provides for disclosures wherein ribbon drive mechanism is disconnected for carriage movements when no imprinting takes place.
