  • Patent number: 9645612
    Abstract: An image-reading apparatus includes a housing having an opening, an image capturing unit that captures an image of a medium disposed at the opening, a plurality of light sources that are disposed inside the housing and emit light toward the opening, and an angle holding mechanisms.

  • Patent number: 9473653
    Abstract: An image reading apparatus comprises a housing to block ambient light and including a rectangular opening on a bottom, an image capturing unit to capture an image of a medium in the opening, and a plurality of light sources disposed in the housing and emitting light to irradiate different areas of the opening. The housing includes four cover portions corresponding to sides of the rectangular opening. The four cover portions include a pair of inclined-cover portions which are switched between an open state and a folded state and a pair of connecting-cover portions which connect the two inclined-cover portions. The two connecting-cover portions are connected to the inclined-cover portions in a transformable manner, and when the two inclined-cover portions are in the folded state, the connecting-cover portions enter gap between the inclined-cover portions by being transformed with respect to the inclined-cover portions.
