Claim:
An image reading apparatus comprising: a document placement portion on which a document is allowed to be placed; a display portion, at least a part of which is transmissive of light; an image reading unit movable along a first direction below the document placement portion and comprising a light emitting unit comprising a red light source, a green light source, and a blue light source, configured to emit light; and a control unit operable to control the image reading unit in a plurality of operation modes, wherein the plurality of operation modes include a first operation mode that allows the image reading unit to be positioned at a first position corresponding to the display portion and causes the light emitting unit to emit the light from at least one of the red light source, the green light source, and the blue light source, the display portion being transmissive of the light emitted from the light emitting unit at the first position, wherein the image reading unit further comprises a light receiving unit, wherein the plurality of operation modes include a second operation mode that allows the control unit to activate the light emitting unit to emit light from all of the red light source, the green light source, and the blue light source and the light receiving unit and to move the image reading unit to perform an image reading operation, wherein the at least one color of light emitted from the light emitting unit in the first operation mode is different from the colors of light emitted from the light emitting unit in the second operation mode, such that the display portion is colored in a color made by the at least one color of the light emitted from the light emitting unit, and wherein, when in the first operation mode, two of the red light source, the green light source, and the blue light source are turned on to create a color that is different from the color in the second operation mode.
