ABSTRACT:
A printed material reader that searches for a desired frame by using blips provided on a printed material, and that prevents search errors due to variances in blip lengths. Before a search of a desired frame, the lengths of the blips adjacent to all the frames on the printed material are detected, and the permissible ranges for the blips are determined from a frequency histogram reflecting relative distributions of the blip lengths detected. The blips whose length fall within permissible ranges are counted to search for a desired frame on the microfilm.
