An automatic document feeder (ADF) for use with an electrophotographic copier, digital copier or similar image recorder for selectively feeding ordinary documents in the form of separates sheets and a continuous document in the form of computer form (CF) paper. Sprocket holes formed through the CF paper are sensed to controllably transport and stop the CF paper on the basis of the number of sensed holes. Even when the first print area of the CF paper is set on a platen by hand, the paper can be surely transported and stopped page by page to the last print area. Regarding the last print area, the stop position is determined on the basis of the number of sprocket holes having been counted until the trailing edge thereof has moved away from a sensor. Hence, whatever the deviation of a print area relative to the CF paper may be, all the print areas including the last print area can be accurately set on the platen to reproduce complete images.
