Abstract
An image input apparatus comprises a stage provided on a substantially horizontal surface of a main body of the apparatus and detachably supporting a film original; a stage scanning mechanism for horizontally moving the stage; an illumination unit provided above the stage and containing a light source for illuminating the film original; and a photoelectric converter for effecting photoelectric conversion of the light transmitted by the film original, wherein the illumination unit can assume a position close to the stage and surrounding the upper and lateral spaces of the stage or a position separated from the stage.
Claims4
An image input apparatus which reads a film original to input an image of the film original, comprising:
- a main body portion;
- a stage provided on a substantially horizontal surface of said main body portion and adapted to detachably support the film original;
- means for effecting horizontal scanning movement of said stage;
- an illumination unit including light source means for effecting transmissive illumination of the film original supported on said stage, and a light-shielding cover;
- a light sensor provided in said main body portion;
- and
- an optical system provided in said main body portion for directing to said light sensor light transmitted from said light source means through the film original supported on said stage;
- said illumination unit being displaceable between a first position close to said horizontal surface and in which said light source means effects the transmissive illumination of the film original in association with the scanning movement of said stage and also in which said light-shielding cover shields said stage from external light, and a second position raised from said horizontal surface to enable mounting of the film original on said stage.
