An image reading device includes: a moving body that is disposed so as to be movable with respect to an image reading device body along a reading portion; a light emitting component that is disposed in the moving body and comprises a plurality of point light sources that are arranged in one row in a substantially orthogonal direction with respect to a moving direction of the moving body; and a light guide body that is disposed adjacent to the light emitting component in the moving body, is placed so as to guide light from the light emitting component to the reading portion, and transmits some light reflected from the reading portion.
