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.
