There is provided an image reading system which can read an image at a high picture quality by having a plurality of light sources arranged on the same plane, an optical guide member for guiding lights irradiated from the plurality of light sources and almost uniformly irradiating an object in a line, a common converging member for converging the lights irradiated from the plurality of light sources so as to enter at least an almost same position in the longitudinal direction on the cross sectional surface of the optical guide member, a line-shaped photoelectric converting device for converting the light from the object irradiated by the optical guide member into an image signal, and a control unit for controlling the plurality of light sources and the photoelectric converting device.
An image reading unit comprising:
An illuminating unit for irradiating an object in a line, comprising:
