Estimating the term…
This invention has as its object to reduce the apparatus scale by simplifying the arrangement of an image reading apparatus for radiating light including both visible and non-visible components, and detecting light obtained from a predetermined image, and provides an image reading apparatus which has illumination means for simultaneously radiating both light including a visible component and light including a non-visible component, and detection means for detecting light obtained from a predetermined image in accordance with the light radiated from the illumination means, including filter means which can be switched in accordance with whether the visible or non-visible component is radiated from the illumination means onto the predetermined image, and control means for controlling a switching operation of the filter means.
An image reading apparatus which comprises first illumination means for radiating a visible light, second illumination means, different from the first illumination means, for radiating non-visible light, and detection means for detecting light obtained from an image in accordance with the visible and non-visible light radiated onto the image from the first illumination means and the second illumination means, said apparatus comprising:
A copying apparatus which comprises first illumination means for radiating visible light, second illumination means for radiating non-visible light, and detection means for detecting light obtained from an image in accordance with the visible and non-visible light radiated onto the image from the first illumination means and the second illumination means, said apparatus comprising:
