  • Publication number: 20190281180
    Abstract: An illuminating device capable of stably illuminating an irradiated object such as a document while suppressing light loss with a simply structure is provided. An LED array and a reflective plate are disposed sandwiching a slit (St) through which light reflected by a document MS passes and a light-guiding member is disposed on the side of the LED array. The light-guiding member includes a direct emission unit disposed between an illumination range y centered on a document reading position and the LED array and an indirect emission unit disposed between the reflective plate and the LED array, a light incidence face of the direct emission unit and a light incidence face of the indirect emission unit are disposed at mutually different position around the LED array, and the LED array is disposed on a side of an interior angle formed by the light incidence faces.

  • Publication number: 20190208074
    Abstract: An image reading device includes an image reader that scans a document so as to read an image of the document. The image reader includes a scanning body in which at least plural mirrors, a condenser lens, and an image sensor are disposed. In the scanning body, concerning positional relationships among the plural mirrors as viewed from a main scanning direction, the plural mirrors are disposed on two sides with respect to an imaginary line extending along an optical axis of reflected light from the document. The mirrors on a corresponding one of the two sides are disposed such that a reflecting position of a mirror on a downstream side in a traveling direction of the reflected light is positioned closer to the document and also to the imaginary line than that of a mirror on an upstream side in the traveling direction of the reflected light.

  • Publication number: 20190191050
    Abstract: An illumination device includes a light guide member having a bar-like shape and a light source disposed so as to face an end surface of the light guide member. The illumination device guides light from the light source in the light guide member and emits the light from a light emission surface of the light guide member formed in a longitudinal direction of the light guide member. The light emission surface includes a first light diffusing portion that is formed in a first portion near the light source and that has a protruding/recessed shape, and a second light diffusing portion that is formed in a second portion adjacent to an end of the first light diffusing portion, the end being away from the light source. The second light diffusing portion has a protruding/recessed shape and has lower light diffusivity than the first light diffusing portion.
