Method of processing a document carrying two kinds of indicia
First Claim
1. The method of processing a document carrying two different kinds of information-bearing indicia;
- said method comprising the steps of;
scanning the document with a closely-spaced and uniformly-spaced series of parallel scan lines to produce corresponding scan data signals;
producing binary scan spot signals representing the presence or absence of indicia elements at closely-spaced and uniformly-spaced point along each scan line;
storing said scan spot data signals;
processing the scan spot data signals representing one of said kinds of indicia to produce corresponding processed data signals;
storing said processed data signals;
said processed data signals and said scan spot data signals being stored so as to provide that (1) the processed data signals can be read out and (2) at least a portion of the stored scans spot data signals can be read out to produce an image reproduction of unprocessed indicia.

Abstract
Apparatus for scanning answer sheets with a series of closely-spaced parallel scan lines to produce scan signals for spots closely-spaced along each scan line, thereby producing a rectilinear data array of binary (black/white) representations at the intersections of a rectangular coordinate grid. Marks on the answer sheet are detected and processed to develop and print-out a score for the examinee by means of a dot-matrix printer. Scan spot signals representing the examinee'"'"'s name written in prior to the test are used to directly control the dot-matrix printer to reproduce the examinee'"'"'s name. The scan spot signals representing the name are stored with and physically accompany the test results, so that at any time the score data can be printed out together with the examinee'"'"'s name.

5. The method of processing a document carrying first and second sets of indicia, one of said sets including alphanumeric characters;
-
said method comprising the steps of; scanning a region of the document encompassing both said first and second sets of indicia; producing binary scan spot data signals constituting a rectilinear data array of binary signals representing the presence or absence of character-or-other-indicia elements at the intersections of a rectangular coordinate grid for said region; processing in a predetermined manner the scan data signals representing one of said sets of indicia to produce processed data signals representing information related to a subject of the other of said sets of indicia; storing said processed data signals for said one set of indicia for subsequent read-out; and storing the scan spot data signals representing said other set of indicia for subsequent direct read-out as reproductions of the geometric shapes of said other set of indicia, the storage of said scan spot data signals preserving the rectilinear data array character of the original indicia and being arranged to permit said direct read-out to present said geometric shapes as a reproduction of the original geometric shapes thereof so as to accommodate visual identification of the information represented thereby.

6. The method of processing a document carrying two different sets of information-bearing indicia;
-
said method comprising the steps of; scanning the document to produce binary scan spot data signals representing the presence or absence of indicia elements at closely-spaced and uniformly-spaced points on the document; processing the scan spot data signals representing one of said sets of indicia to produce corresponding processed data signals; said processed data signals and at least a portion of said scan spot data signals being stored so as to provide that (1) the processed data signals can be read out and (2) at least said portion of said stored scan spot data signals can be read out to produce an image reproduction of unprocessed indicia.

7. The method of processing a document carrying first and second sets of indicia, one of said sets including alphanumeric characters;
-
said method comprising the steps of; scanning a region of the document encompassing both said first and second sets of indicia; producing binary scan spot data signals constituting a rectilinear data array of binary signals representing the presence or absence of character-or-other-indicia elements at the intersections of a rectangular coordinate grid for said region; processing in a predetermined manner the scan data signals representing one of said sets of indicia to produce processed data signals corresponding to said one set of indicia; and storing the scan spot data signals representing said other set of indicia for subsequent direct read-out as reproductions of the geometric shapes of said other set of indicia, the storage of said scan spot data signals preserving the rectilinear data array character of the original indicia and being arranged to permit said direct read-out to present said geometric shapes as a reproduction of the original geometric shapes thereof so as to accommodate visual identification of the information represented thereby.
