Beschreibung
Zusammenfassung:	In a film image reading out device, in which one surface of a film, where images are recorded, is scanned repeatedly with a laser light beam along a scanning line and images are read out by detecting continuously light, which has passed through the film, while moving the film with a low speed in the direction, which is perpendicular to the scanning line, a light diffusing member is disposed closely to the surface opposite to that of the film scanned with the laser light beam and the optical density of the film is detected continuously by leading transmitted and diffused light to a photodetector by means of a bundle of optical fibers.
