ABSTRACT:
The present invention discloses an image reading apparatus which enables high-speed reading of an image transmitted through a transparent material such as a photographic film or an image reflected by a reflective material. In the image reading apparatus, a transparent material such as a photographic film is first conveyed in a conveying direction thereof, and an image frame to be read is positioned at a reading position. After the image frame is positioned, light emitted from a lamp is made into slit light by a light diffusion box, a longitudinal direction of the slit light coinciding with the conveying direction of the photographic film, and the slit light is irradiated on a portion (line) to be read of the photographic film. Light transmitted through the portion of the photographic film is imaged by a lens unit onto a light-receiving surface of a line CCD (a reading sensor) which is disposed along the longitudinal direction of the photographic film. The photographic film is moved by sub-scanning means in a direction substantially perpendicular to the direction the photographic film is conveyed, and the position of a subsequent portion (line) to be read is determined. In this way, an image recorded on the photographic film is read line by line along a longitudinal direction of the image frame.
