    Abstract: A scanner housing encloses a rotatable cylindrical drum (28), the outer surface having opposing rims supporting respective outer edges of a film strip. The edges are releasably held flat against respective rims by means of bands (52, 54) contacting respective radially outer edges of the film to maintain them against the respective outer rim surfaces. A scanner assembly (72) is disposed internally of the housing adjacent one outer side of the drum (28).
    A light source (114) is located adjacent an opposing outer side of the drum (28) at a location substantially diametrically opposed from the scanner assembly (72).
    A focusing lens assembly (42) is disposed internally of the drum (28) between the light source (114) and the scanner assembly (72). The film being carried on the outer circumference of the rotating drum (28) as the drum rotates, passes adjacent the light source (114). Light from the source (114) thereby is directed through the film, the lens assembly (42), and impinges upon the scanner assembly (72) whereupon the portion of the film adjacent the light source is thereby scanned (172).

    Abstract: PROBLEM TO BE SOLVED: To provide an information detecting device for a film scanner which is free of an increase in cost due to an increase in arrangement space or complexity of device constitution.
    SOLUTION: In the film scanner, a plurality of optical sensors previously detecting preliminary information on the screen position, size, etc., of a frame image of a photographic film when the frame image is read are incorporated. A light emitting element unit 52 which emits a plurality of kinds of light beams differing in wavelength is used as a light source emitting sensor light beams of the optical sensors. The light emitting element unit 52 is constituted by arraying chip type LEDs 54G, 54O, and 54W emitting light beams differing in wavelength on a pedestal 56 and packaging them in one. The LEDs 54G, 54O, and 54W emit green, orange, and white light beams respectively. Light emission colors of the light emitting element unit 52 are switched according to the kind of preliminary information and the kind of the photographic film.

    Abstract: PROBLEM TO BE SOLVED: To relax accuracy in movement, when using a miniaturized area sensor to shift pixels.
    SOLUTION: An imaging part 20 of an image reading apparatus 11, constituting a digital laboratory system 10, is composed of an image forming lens unit 23, a lens barrel 24, a support plate 25, a CCD area sensor 26 and the like. The image forming lens unit 23 is held by the lens barrel 24 which is freely movable in the direction of an optical axis 21. The lens barrel 24 is mounted on the lower surface side of the support plate 25, and the CCD area sensor 26 is mounted on the upper surface side of the support plate 25. The support plate 25 includes piezoelectric elements 35a, 25b (not illustrated) for moving the imaging part 20 in a direction at 45° to the film length direction and breadth direction. Since the image forming lens unit 23 and the CCD area sensor 26 can be moved integrally, moving accuracy can be relaxed, when pixels are shifted.
