ABSTRACT:
A photographic film is prevented from being damaged by dust adhering thereto due to static electricity generated in the photographic film during the feeding thereof. A brush for removing the static electricity as being a conductive member is brought into contact with a portion of the photographic film other than a photographic exposure surface. Furthermore, the brush is grounded through a line to a casing of a film image input system, which has electric potential 0. With this arrangement, the static electricity generated in the photographic film during the feeding thereof can be removed through the line from the brush for removing the static electricity. Thus, the static electricity is not accumulated in the photographic film and the dust does not adhere to the photographic film. Therefore, the photographic film can be prevented from being damaged by the dust.
