DEFINITION

Classification: 400/313

Carriage-return mechanism:

(under subclass 283) Subject matter wherein the carriage* is caused to be moved in a direction opposite to the typing (i.e., character-space*) direction that enables the character* symbols to be imprinted in succession, and wherein the movement in said opposite direction is regulated to retrogress the carriage back to the beginning of a print-line*.

(1) Note. The carriage is usually returned until it is stopped by a margin* regulator or margin-stop* element. In some typewriters the carriage return may be modified to stop at a preset position to permit the first character of a new print-line to be indented from the margin*.
