    摘要： An image scanner is provided which is capable of preventing decrease in image contrast and improving the reading accuracy and quality of color images to a greater extent. An image scanner includes a unit case having an opening formed on one end surface thereof; light-source lamps and light-source lenses which are disposed in the inner portion of the opening of the unit case in such a manner as to face the opening; holding plates which are disposed in the inner portion of the opening of the unit case and which have formed therein slits for extending the terminals of the light-source lamps to the inside of the unit case; and CCD sensors, disposed at the end portion of the inside of the unit case on the side opposite to the opening, for reading an image of the original document by receiving, via a lens unit, light which is radiated onto a given original document placed near the opening from the light-source lamps via the light-source lenses and reflected from this original document.

    摘要： An image reading device has a light emitting unit. The light emitting unit has a light emitting portion, a light guiding member, a holding member and a case member. The light guiding member is disposed along a main scanning direction, and an end portion of the light guiding member faces the light emitting portion. The light guiding member has a light irradiating portion which emits light to an outside. The holding member holds the light emitting portion and the light guiding member. In addition, the holding member has a first holding portion that directly or indirectly positions and holds the light emitting portion, and a second holding portion that positions and holds one end or both ends of the light guiding member. The case member houses the holding member that is in a state of being positioned.

    摘要： An image reading device includes a light source member having light source portions that release light; a light guide member that has an input section facing the light source portions and to which the released light is input, and an output section outputting the input light, and that guides the light toward a predetermined radiation position; a support member supporting the light source member and the light guide member and having higher rigidity than them; a retaining member retaining the light guide member in a supported state by the support member by pressing the light guide member toward the support member; a contact section that is provided in the light guide member, comes into contact with the retaining member, and protrudes from the light guide member toward the retaining member; and a reader member receiving the light from the radiation position so as to read an image thereof.
