  • Image reading system
    Patent number: 7225986
    Abstract: An image reading system which reads the images of a detectable object comprising an image display device that has an image display area to display images having luminosity corresponding to the display gradation and radiates the display illumination according to this luminosity; a detection surface in which the entire image display area of the image display device is covered with a laminated layer arrangement and a detectable object is placed; an image reading device comprising a first sub-area in the detection surface on which the detectable object is placed and a second sub-area which consists of an area corresponding to at least a portion of the area of the image display area except for the first sub-area; and a plurality of photosensors arranged in a matrix form provided in the first sub-area and second sub-area which has uniform transmittance, wherein at least a portion of the display illumination is permeated and the image of the detectable object is read in the first sub-area.
