Abstract
PURPOSE:To improve convenience in use by providing well-lighted back illumination by increasing the reflecting properties of a printed circuit board, by treating silk printing in white on the whole surface on the side of a printed circuit board on which parts are installed, and by printing the letters of a cooking menu and the symbols of parts by cutout printing on the silk printing. CONSTITUTION:When a cake key 3 is depressed, for example, the whole area of the key pad of a cake key 3 is emitted, and the whole area of it is flickered at predetermined time intervals in order to show a heating operation proceeding. A switch 7 is depressed by the intermediary of a transparent actuator 6 and a lamp 8 is turne ON by depression of the key pad part of a cake key 3. The lights of a lamp 8 turned ON illuminate the key pad part of a cake key 3 from the back, directly partly, and by reflection partly. The whole surface of a printed circuit board 10 is treated by silk printing in all white and items on a cooking menu are printed by cutout printing. Negative letters are printed on a positive surface reversely, so that brighter back illumination can be obtained by the same electric power consumption by the lamp 8.
