Abstract: PROBLEM TO BE SOLVED: To actualize keyboard lighting which saves the space and has small power consumption, is usable even by battery driving, and exerts no adverse effect on a display device by irradiating a keyboard with the light emitted by an LED through an opening part. SOLUTION: When a computer 10 is used, a rear cover 105 is opened and stopped at 90 deg. or more and the keyboard 103 is operated while looking at an LCD. The computer 100 is provided internally with an LED holder 150 holding the LED for keyboard lighting and an LED switch 113. An opening part is formed in the bottom of the LED holder 150; and part of the light emitted by the LED is cut off by the bottom part and the rest is emitted out of the LED holder 150 through the opening part. While the rear cover 105 is opened, the LED is turned on by operating the switch 113 to light up the keyboard 103.
