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.

Claims

1. The method of processing pre-printed answer sheets comprising the steps of:

entering the examinee'"'"'s name on the sheet using alphabetic characters;

entering marks to indicate responses to questions;

illuminating the sheet;

scanning the sheet with a closely-spaced series of parallel scan lines to detect radiation from the sheet along the scan lines;

producing scan spot data signals representing received radiation at closely-spaced points along each scan line;

processing the data signals representing the marks inserted on the sheet so as to produce a score for the examinee;

storing the processed mark signals; and

storing the scan spot data signals representing the examinee'"'"'s name entered on the sheet together with said processed mark signals.

2. The method of claim 1 including the steps of:

printing out said score; and

printing out the examinee'"'"'s name from said stored name-representing data signals along with said score.

3. The method of claim 2, wherein said score and said examinee'"'"'s name are printed out with a dot-matrix printer.

4. Apparatus for processing pre-printed answer sheets wherein the examinee'"'"'s name is entered on the sheet using alphabetic characters and marks are entered in designated positions to indicate responses to questions;

said apparatus comprising;

means for illuminating the sheet;

means for scanning the sheet with a closely-spaced series of parallel scan lines to detect radiation from the sheet along the scan lines;

means producing scan spot data signals representing received radiation at closely-spaced points along each scan line;

means for processing the data signals representing the marks inserted on the sheet so as to produce a score for the examinee; and

means for storing the scan spot data signals representing the examinee'"'"'s name together with processed mark signals.

5. Apparatus as claimed in claim 4, including:

means for printing out said score and for printing out the examinee'"'"'s name from said stored name-representing data signals.

6. Apparatus as claimed in claim 5, wherein said print-out means comprises a dot-matrix printer.
