DEFINITION

Classification: 358/494

Linear scanning pattern:

(under subclass 474) Subject matter wherein the surface is traversed a series of straight lines.

(1) Note. Included in this subclass are scanning mechanisms wherein the surface may be cylindrical or curved, but the scanning is performed in a straight line parallel to the axis the cylinder or curved surface.

346, Recorders,

139, for marking devices wherein a marker moves in a straight line.

347, Incremental Printing of Symbolic Information,

223+, for plural beam scanning apparatus and method, particularly subclass 238 for marking a scanned medium using light emitting diodes, and subclasses 129+ for generic electric markers where an electrostatic image is formed on a medium or discharged from a medium by scanning the medium with beam of light emitted from a light source, particularly subclass 130 for such an apparatus using light emitting diodes as the light source.
