DEFINITION

Classification: 400/519

Carbon paper carrier movable rectilinearly:

(under subclass 518) Subject matter wherein said carrier for said carbon paper is movable along a straight line.

(1) Note. The path of movement of the carrier is usually along a line that extends at right angles to the axis of the platen* and substantially tangent to the circumference of the platen. The support for the carrier may extend to the rear of the typewriter in a substantially horizontal disposition or may extend substantially vertically from a member fixed at the back of the typewriter.
