ABSTRACT:
There is disclosed a film scanner for scanning picture frames on photographic film. A plurality of filmstrips are spliced into a long photographic film web (17) and wound around a reel when placed in a film supply device (42) of the film scanner. The photographic film web is advanced from the supply reel through a film passageway to a film wind-up device (44). The film supply device and the film wind-up device are provided with loop formers (83, 91) for forming loops (17c,17d) of the photographic film web before and behind a movable film table (52). After a picture frame of the photographic film web is positioned and fixed in a light permeable window (56) of the film table, the film table is moved back and forth along the film passageway. In synchronism with the reciprocating movement of the film table, the film scanner sequentially makes pre-scanning, focusing and fine scanning.
