A second case4is connected to a first case2so as to be in open and closed positions with respect to the first case2. A main display section11which is exposed when the second case4is in the open position, a sub-display section12which is exposed whether the second case4is in the open or closed position, a main illuminating device23A which illuminates the main display section11, and a sub-illuminating device23B which illuminates the sub-display section12are provided. A driver24which selects a line to supply electric power for illumination to the main illuminating device23A or the sub-illuminating device23B, and a detecting switch22which detects whether the second case4is in the open or closed position, are also provided. A control section25is also provided which controls the driver24, with reference to the detected result, to supply electric power to the main illuminating device23A when the second case4is in the open position, and to supply electric power to the sub-illuminating device23B when the second case4is in the closed position.
