DEFINITION

Classification: 400/516

By simultaneously advancing record-medium and retracting carbon paper:

(under subclass 513) Subject matter wherein the record-medium* is moved in a direction to line-space* the record-medium, and said carbon paper is moved in the opposite direction at the same time, both movements occurring after typing of one page* of text and before typing on a subsequent page of text.

(1) Note. The movements referred to above do not occur during typing on a particular page of text. Rather during the typing of a page both the record-medium and carbon paper materials move in the same direction, and the specified movements occur between successive pages.
