Abstract
Abstract A remote optical character recognition system including a central processor time-shared among a number of remote scanner units each adapted to receive a document bearing information characters to be scanned so as to produce corresponding signals which are transmitted to the central processor for analysis, whereby signals are developed identifying each of the information characters on the document. The document is additionally provided with control characters presented with a distinctive characteristic to enable the central processor to distinguish the control characters from the information characters. The central processor identifies the control characters and produces corresponding control effects related to procedures for scanning the document and processing the scan data. Certain of the control characters provide basic information concerning the particular customer whose document is being scanned, as well as initial instructions such as specifying portions of the document to be scanned. Other control characters relate specifically to corresponding information characters placed in directly associated data fields on the document.

Claim 1
Independent Claim
314 words
A record medium for storing data entered in the form of alphanumeric characters to be scanned by an optical character recognition apparatus having facilities to analyze scan signals to provide recognition of such characters and processing of the stored data comprising: a record member comprising a document to be scanned by an optical character recognition scanner; a plurality of sets of indicia means formed on said document with each set defining a series of horizontally-adjacent separate rectangular spaces each dimensioned to have entered therein a corresponding individual two-dimensional alphanumeric information character the shape of which carries intelligence, the sets of characters when entered representing respective fields of data to be stored in said record member; said sets of indicia means being positioned in different locations on said record member yet all being located to be scanned by said optical character recognition scanner; and a plurality of two-dimensional alphanumeric field code characters formed on said record member and having shapes carrying instructional intelligence, said field code characters being arranged in a series of separated locations each positionally related in a predetermined manner with respect to and closely adjacent the location of a respective one of said sets of indicia means; said field code characters carrying said instructional intelligence embodied in the two-dimensional shapes thereof to permit recognition analysis thereof by the same facilities of said optical character recognition apparatus used to recognize said information characters; said field code characters being provided with distinctive stylistic configurational characteristics embodied in the character format of at least certain of the field code characters and serving to permit said optical character recognition apparatus to distinguish the field code characters from said alphanumeric information characters, said field code characters, upon scanning and recognition by said optical character recognition apparatus, serving to provide to that apparatus instructional intelligence for directing the processing by that apparatus of the corresponding alphanumeric information characters.
Claim 2

314 words
A record medium for storing data entered in the form of alphanumeric characters to be scanned by an optical character recognition apparatus having facilities to analyze scan signals to provide recognition of such characters and processing of the stored data comprising: a record member comprising a document to be scanned by an optical character recognition scanner; a plurality of sets of indicia means formed on said document with each set defining a series of horizontally-adjacent separate rectangular spaces each dimensioned to have entered therein a corresponding individual two-dimensional alphanumeric information character the shape of which carries intelligence, the sets of characters when entered representing respective fields of data to be stored in said record member; said sets of indicia means being positioned in different locations on said record member yet all being located to be scanned by said optical character recognition scanner; and a plurality of two-dimensional alphanumeric field code characters formed on said record member and having shapes carrying instructional intelligence, said field code characters being arranged in a series of separated locations each positionally related in a predetermined manner with respect to and closely adjacent the location of a respective one of said sets of indicia means; said field code characters carrying said instructional intelligence embodied in the two-dimensional shapes thereof to permit recognition analysis thereof by the same facilities of said optical character recognition apparatus used to recognize said information characters; said field code characters being provided with distinctive stylistic configurational characteristics embodied in the character format of at least certain of the field code characters and serving to permit said optical character recognition apparatus to distinguish the field code characters from said alphanumeric information characters, said field code characters, upon scanning and recognition by said optical character recognition apparatus, serving to provide to that apparatus instructional intelligence for directing the processing by that apparatus of the corresponding alphanumeric information characters.
Claim 3
Dependent Claim
26 words
A record medium as claimed in claim 1, wherein said field code characters are located immediately to the left of the corresponding set of indicia means.
