DEFINITION

Classification: 400/671

End of maximum typed line:

(under subclass 668) Subject matter wherein the preventing means is made effective when the typewriter carriage* that is moving in a character-space* direction arrives at a predetermined position relative to the typewriter.

(1) Note. In most typewriters, the position is determined by a margin* regulator (usually the right-hand-margin regulator for English or other European languages), and the locking means prevents further carriage movement as well as movement of any of the character*-key* elements. The locking means may usually be disengaged, however, to permit the typing of several more characters on the same line.
