ABSTRACT:
The present invention relates to document positioning and feeding apparatus for high speed printers, such as normally associated with data processing systems. The document feeding apparatus is particularly adapted to provide high quality, high speed printing of stock consisting of multiple pages or non-uniform thicknesses. It is useful for the printing of savings-books, checks and statement of account forms. The apparatus utilizes a unique coupling means to maintain equal and opposite rotation of the feeding elements and to substantially reduce relative rotary motion between the feeding elements during the feeding of stock into the printer. Novel support means allow the feeding elements to accommodate stock having a different thickness for one part of the stock compared to another part.
