(under the class definition) Subject matter for the analysis of intrinsic properties of documents which includes a support for the document to be tested and means to examine and compare visually or to examine photoelectrically the properties of the document by means of visible light for the conformance of any given property with a standard or for the conformance of the pattern or writing generally with a standard pattern or writing as to form or configuration.
(1) Note. A document for this subclass is a sheetlike article and may be an information document having writing or printing or containing a pattern. A document is, however, excluded from this subclass when any writing, printing, or pattern contained on the document is examined for the information it conveys.
(2) Note. The analysis of the intrinsic properties of a document by means of radiant energy (nonvisible light), is classified in Class 250, Radiant Energy.
(3) Note. The analyzing of coded cards, having perforations, magnetic markings and visible markings, one at a time in business machines as well as the cards, per se, are
in Class 235, Registers.
(4) Note. Termatrix Systems (peekaboos) are found in Class 235, Registers, subclass 1; Class 250, Radiant Energy, subclasses 211 and 219. Also see Class 355, Photocopying, for projectors involving peekaboo systems.
SEE OR SEARCH THIS CLASS, SUBCLASS: 2, for contour plotting apparatus involving stereoscopic images of topos:graphical maps.
389, for mensuration or configuration comparison generally where a photograph is taken of the standard or object to be compared.
391, for configuration comparison generally of an article with a standard where light projection is involved.
394, for configuration comparison generally of an article with a desired shape.
