Claim:
1. An image-reading apparatus comprising: a housing that shields environmental light and has an opening on a bottom face; an image capturing unit that captures an image of a medium exposed to inside of the housing at the opening; and a plurality of light sources that are disposed inside the housing and emit light toward the opening to be emitted onto different regions of a horizontal plane at the opening, wherein the opening is formed in a rectangular shape, the housing includes at least four cover units corresponding to sides of the opening, the four cover units include two inclined cover units that are inclined from a side on which the opening is positioned toward an opposite end in a direction in which the two inclined cover units get closer to each other and two coupling cover units that couple the two inclined cover units to each other, the two inclined cover units include a first inclined cover unit and a second inclined cover unit, the two inclined cover units are switchable between an opened state in which the first inclined cover unit moves relatively to the second inclined cover unit based on an end opposite to a side on which the opening is positioned and ends of the two inclined cover units on the opening side are separated away from each other, and a folded state in which the two inclined cover units are adjacent to each other in parallel, the two coupling cover units are coupled to the two inclined cover units in a deformable manner, and deformed with respect to the two inclined cover units to enter a space between the two inclined cover units when the two inclined cover units are in the folded state, and the image-reading apparatus further comprises an angle holding mechanism that holds the two inclined cover units so that the ends of the two inclined cover units on the opening side are separated away from each other when the two inclined cover units are in the opened state.
