Abstract
A film holding apparatus for use with a scanner is provided. The film holding apparatus selectively holds a positive film and a negative film that are to be scanned. The positive film is thicker than the negative film. The film holding apparatus includes a base, a plate disposed above the base, and a pressing unit disposed above the plate. The plate has a surface for selectively receiving a positive film and a negative film. When the surface of the plate receives the positive film, the plate vertically moves for a distance toward the base. When the surface of the plate receives a negative film, the negative film is held between the surface of the plate and the pressing unit.
