  • Image reading apparatus for selectively illuminating a first object and a second object by the same light beam and selectively detecting imaged image information therefrom
    Patent number: 5566006
    Abstract: In an image reading apparatus, a first object and a second object are adapted to be illuminated on different regions each other with a light beam from a light source by an illuminating device. A first imaging optical system is provided to image image information of the first object on a single photoelectric converting device. A second imaging optical system is provided in an optical path different from that of the first imaging optical system so as to image image information of the second object onto the photoelectric converting device. The first and second object to be illuminated, and the photoelectric converting device are relatively displaced to read the image information of the first and second objects.
