    Abstract: A lighting device includes a light source that illuminates an object of illumination, a reflecting member provided opposite the light source so as to direct a first part of illuminating light emitted therefrom to the object of illumination, and a light-blocking member provided between the light source and the object of illumination and between the reflecting member and the object of illumination. The light-blocking member blocks the first directed part of the illuminating light and a second part of the illuminating light directly illuminating the object of illumination with a certain ratio of a light-blocking rate for the first directed part of the illuminating light to a light-blocking rate for the second directly illuminating part of the illuminating light.

    Abstract: A contact image sensor module has a light source, at least one reflective element and a photoelectric conversion element. The photoelectric conversion element is arranged between the light source and the reflective element, such that the light from the light source is directed toward the manuscript. The reflective element receives the light reflected from the manuscript, and then the light is reflected back to the manuscript. The photoelectric conversion element receives light directed from the light source and the reflective element toward the manuscript, and then the light is converted into an electric signal, thus eliminating the dark band problem of the manuscript.

    Abstract: A line-illuminating device comprises a white casing, a bar-shaped light guide housed within the casing, and light-emitting units provided on opposite ends of the bar-shaped light guide. The light-emitting unit has a substrate forming a circuit on which a lead wire for power supply is installed. Formed on a surface of the substrate facing the bar-shaped light guide is a window for coupling in which a green-color light-emitting diode and a blue-color light-emitting diode are installed. Likewise, the light-emitting unit has a substrate on which a lead wire for power supply is installed. Formed on a surface of the substrate facing the bar-shaped light guide is a window for coupling in which two red-color light-emitting diodes are installed.
