Abstract:
An image reading apparatus, comprising:a conveyor mechanism to convey a film having a plurality of frame images recorded thereon; a light source to emit light such that the light is transmitted through or reflected from the plurality of frame images recorded on the film; and a line scanner to read the light transmitted through or reflected from the plurality of frame images recorded on the film; wherein said light source comprises: a first plurality of light emitting elements, each light emitting element of the first plurality of light emitting elements emitting light of a first color having a substantially same, first wavelength; a second plurality of light emitting elements, each light emitting element of the second plurality of light emitting elements emitting light of a second color having a substantially same, second wavelength; a third plurality of light emitting elements, each light emitting element of the third plurality of light emitting elements emitting light of a third color having a substantially same, third wavelength; and a photoconductive member having a light entering surface, which faces said first, second, and third plurality of light emitting elements and into which light emitted by said first, second, and third plurality of light emitting elements enters, and having a light exiting surface, which faces said film and from which light that enters the light entering surface exits, wherein said photoconductive member has a generally trapezoidal cross section.
