ABSTRACT:
A linear light source having a relatively large numerical aperture emits reading light of a substantially fully diffused light intensity distribution toward a film original that is held between support glass panels. The reading light passes through the film original and then through a slit that is disposed as a field stop between the film original and a reading lens and positioned closely to the film original for limiting a field of view with respect to the reading light. The reading light that has passed through the slit is converged by the reading lens onto CCD line sensors each having the same field of view as that of the slit.
