DEFINITION

Classification: 400/511.2

With retraction of carbon paper for reuse thereof (e.g., by slidable carrier):

(under subclass 511) Subject matter wherein said carbon paper is advanced from a wound roll in a first direction toward the platen* for use in typing carbon copies, and wherein said carbon paper is drawn back in a second direction opposite to the first direction so that the carbon paper may be used again in a subsequent typing operation while it is advanced in the first direction for use in typing carbon copies.

(1) Note. The retraction of the carbon paper usually occurs at the completion of one page* (e.g., one form of a plurality of business forms) on the record-medium* web and is for the purpose of repositioning the carbon paper between the next forms to be typed. When the pigment on the carbon paper is depleted, the worn portion of carbon paper is torn off and a fresh supply pulled from the wound roll of carbon paper. In

this subclass the carbon paper roll is mounted on a slidable carrier and the movement of the carrier effects advancement and retraction of the carbon paper.
