ABSTRACT:
Combination automatic feed systems and sheet readers are provided by this invention which include aligning and picking mechanisms for transporting and laterally aligning a sheet of paper relative to a flow path. The system includes a microprocessor for delivering a sheet to the alignment mechanism whereby a timing of this delivery by the automatic feeding mechanism is coordinated with the timing of the reading of the sheets in the sheet reader to compensate for both regular and irregular delays in reading the sheets, for example, during the grading of test scores. Methods for automatically feeding, reading and aligning sheets for a sheet reader are also provided.
