  • Image reader having spectroscope for color separation
    Patent number: 4873569
    Abstract: A spectroscope (20) and a multi-row image sensor (40) are fixed to each other. Light from an original is supplied through an image-formation optical system to a spectroscope, which in turn separates the light into a plurality of color light components (LR, LG, LB). the color light components form linear images on light receiving surfaces of linear image sensors (42R, 42G, 42B) respectively. Respective image-formation positions of the color light components have a common conjugate position (P).
