PROBLEM TO BE SOLVED: To provide an inexpensive alarm clock capable of performing awakening action quickly, thereby ensure waking. SOLUTION: Not only a sound as awakening function but also light incorporated with an electric bulb or the like is used, by knowing that a nerve existing on the back of an eyelid transmits a signal to the brain, and by utilizing a person's nature that he/she wakes up when a dark room is suddenly lit up. Either kind of a flashing type and a continuously-lighting type can be used as well as the kind of awakening sound function. A desk lamp and the alarm clock can be incorporated together. |
