Abstract
A system for selectively effecting operation of a copying or facsimile machine in accordance with the textual content of a scanned document. The system includes an optical character reader which generates scanned character code signals representative of characters comprising at least a portion of the text of the document, a memory for storing at least one correlation criterion, and a processor for selectively effecting operation of the copying or facsimile machine in accordance with the correlation of the criterion to the text.
Claims19
A system for selectively effecting operation of a copying apparatus in accordance with the textual content of a scanned document, said copying apparatus including an operation control circuit responsive to control signals applied thereto for actuating said copying apparatus, said system comprising:
- optical character reader means, for generating respective scanned character code signals indicative of the respective characters comprising at least a portion of the test of said document;
- memory means for storing indicia of at least one correlation criterion in respect of said portion of text;
- and
- processor means, responsive to said scanned character code signals, for selectively generating said control signals to said operation control circuit for enabling or inhibiting said copying apparatus in accordance with a correlation of said criterion with said portion of text.
A method of selectively effecting operation of a copying apparatus in accordance with the textual content of a document, comprising the steps of:
- optically scanning said document to generate respective character code signals indicative of the respective characters of the text of a portion of said document;
- correlating said code signals with at least one predetermined pattern of characters, to determine the existence of said predetermined pattern of characters in the text of the portion of said document;
- and
- selectively effecting operation of said copying apparatus in accordance with the results of said correlation.
A system for selectively generating a copying actuation signal in accordance with the text of a document, comprising:
- an optical scanner for generating respective character code signals indicative of a portion of the text of said document;
- a random access memory for storing indicia of said character code signals;
- processor means, cooperating with said random access memory, for making a determination of the presence of a predetermined sequence of characters in said portion of said text and selectively generating said copying actuation signal in accordance with said determination.
