Abstract
An apparatus for reading images of a photographic film disposed on an image reading optical path, with a light source ( ) for emitting visible light and infrared light into the image reading optical path to irradiate the photographic film, and a zoom lens unit ( ) for the visible light and infrared light irradiating the photographic film. A visible light sensor and an infrared light sensor are disposed separately for detecting a visible image based on the visible light from the zoom lens unit, and for detecting an infrared image based on the infrared light from the zoom lens unit, respectively. A focal position varying transparent element (FT) is provided for shifting a focal position of the zoom lens unit along an optical axis. The transparent element is movable to and from a position between the zoom lens unit and infrared light sensor to correct variations in the focal position occurring with variations in magnification of the zoom lens unit.
