    摘要： An image sensor comprises signal generation unit for generating an image signal on the basis of reflected light using a plurality of photoelectric converters arranged on a substrate, and image forming unit for projecting the reflected light, from an original image, within a predetermined area on the substrate on which the signal generation unit is provided, wherein the signal generation unit includes signal output unit for outputting the image signal from the plurality of photoelectric converters to the outside of the signal generation unit, and a part or all of the signal output unit is arranged outside of the predetermined area on the substrate. Accordingly, reflection of light by the electrodes is prevented, and no light noise incidents on the photoelectric converters. Therefore, it is possible to increase the S/N ratio of the image sensor.

    摘要： In an image sensor having a photoelectric conversion element for receiving light, an illumination unit, and a lens array in which a plurality of gradient index lens elements for focusing light reflected by an original onto the photoelectric conversion element are arrayed, part of the peripheral portion of the lens of the gradient index lens element in the radius direction contains a light absorber for absorbing light having a predetermined wavelength other than the wavelength distribution of light emitted by the illumination unit. With this arrangement, since the optical influences of the peripheral portion of the lens element, which degrade the lens resolution can be eliminated, and the lens elements can be accurately arrayed, there can be provided an image sensor which is free from crosstalk between the lens elements although the lens elements are arrayed in tight contact with each other, and has a large focal depth by changing the angular aperture, high performance, and hardly any performance variations in mass production, and an information processing system using the image sensor.

    摘要： In an image reading device in which an original is illuminated by a light source, and a reflected beam from the original is imaged on a sensor through a rod lens array, a light-shielding member is arranged between the beam exit surface of the light source and the incident surface of the rod lens array to prevent the beam from the light source from being directly incident on the rod lens array to cause a flare. An image reading device and information processing apparatus in which the image quality is rarely degraded by the flare beam are provided.
