<p>A scanning device for storage foils (12) comprises a scanning and transport unit (14) having a fast rotary deflecting element (54) to generate a reading light beam (36) rotating in a plane. A storage foil (12) arranged on a part-cylindrical support wall (28) is moved in axial direction by means of drive belts (70). Thus the storage foil is read along a helical line of small pitch.</p> |
