Classification: 358/400


(under the class definition) Subject matter including generating and transmitting, recording, reproducing, or displaying a scanned image representative electrical signal in which the local light variations composing the image are not subject to variation with time.

(1) Note. Image includes s:graphical, text or pictorial matter.


178, Telegraphy,

37, for secret (i.e., automatic) insertion of printing telegraph recorder paper into an envelope.

345, Computer Graphics Processing, Operator Interface Processing, and Selective Visual Display Systems,

467, 472 for character font generation and subclasses 326+ for operator interface processing. 347, Incremental Printing of Symbolic Information,

224+, for radiation marking, particularly subclasses 225+ for marking a medium by scanning the medium with a writing beam (e.g., light, electron), and subclasses 129+ for generic electric marker where an electrostatic image is formed on a medium or discharged from a medium by scanning the medium with a beam of light.

371, Error Detection/Correction and Fault Detection/Recovery, appropriate subclasses for error detection, correction, recovery or prevention in pulse code data or computers.

379, Telephonic Communications,

93+, for digital facsimile and subclass 100 for facsimile combined with a telephone or telephone system.

380, Cryptography,

18, for encrypted facsimile transmission.

395, Information Processing System Organization,

80+, for data processing of robot control systems 186+ for security.

399, Electrophotography, for electrophotos:graphic devices without facsimile signal or without electric signal control of the light used to form the electrophotos:graphic image,

9+, for diagnostics, subclasses 38+ for controls, subclasses

130+ for image formation, subclasses 168+ for charging, subclasses 177+ for exposure, subclasses 222+ for development, subclasses 297+ for transfer, subclasses 320+ for fixing, subclasses 343+ for cleaning, and subclasses 361+ for document handling. 430, Radiation Imagery Chemistry: Process, Composition, or Product Thereof,
