    Abstract: An operation unit comprises a touch panel display, a home key and a power saving key. The power saving key includes an indication portion, and a first indication portion out of the indication portion has light permeability, and a color of its surface is a dark color, and a second indication portion has no light permeability or has it hardly, which is constituted by a double-layered print. In a surface side of this second indication portion, a figure indicative of a power saving key is printed in silver ink, and in a rear side thereof, a figure indicative of the power saving key is printed in black ink. In a normal state, when a backlight is lit, a surface of the first indication portion is bright, and a surface of the second indication portion is darker than the surface of the first indication portion. On the other hand, in a power saving mode, when a light guide plate does not emit light, the surface of the first indication portion is dark, and the surface of the second indication portion is brighter than the surface of the first indication portion. Therefore, presence and location of the power saving key can be notified in a visible manner.
