Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
242 words
A scanning apparatus, comprising: a. a cable of optical fibers, the cable at each end being spread to form a line of individual fibers arranged in the same order at each end to derive a single scanning line from a copy bearing a visual image, b. a self-propelled carriage holding one end of the cable adjacent the said copy, c. a first elongated supporting roller mounted in the carriage and resting on the copy with its axis of rotation parallel tO and spaced from the said line of fibers, d. a motor mounted on the carriage and connected to the roller for driving the same, e. a second elongated supporting roller mounted in the carriage and resting on the copy with its axis of rotation parallel to and spaced from the said line on the opposite side thereof from the first roller, the two rollers serving to smooth the copy in the neighborhood of the line, f. a pair of illuminating means mounted in the carriage adjacent the copy, on opposed sides of the one end, and spaced from the copy a greater distance than the one end, g. a scanner to which the other end of the cable is attached for deriving an electrical signal representative of the said visual image, and h. an electrical cable extending along and fixed to the optical fiber cable from the scanner to the carriage to supply power to the motor and the illuminating means.
