  • Patent number: 5315346
    Abstract: Scanners for use in photofinishing operations are well-known. However, many known devices suffer from the problem of being bulky and/or having a limited range of functions. Described herein is a scanner (10) formed by a bundle of optical fibres which enables information on a film (12) to be determined. The bundle of optical fibres is divided into two sets, one which scans the film (12) through slit 1 for information relating to frame (20), and a second set which scans the film (12) through slits (2, 3, 4, 5) for other information such as DX codes (24), frame numbers or sprocket holes (26) contained in the edge (22) of the film (12). Information from the film (12) is passed to a computer (30) via an interface (28) and the information derived is used to actuate means (32).
