Abstract: To provide a protrusion drop structure and others in which when a load applied to an operating button in a back direction is smaller than a predetermined load, the bending of a printed circuit board is made sufficiently small so as not to give a feeling of strangeness when a user depresses the operating button, and when a load applied to the operating button in the back direction reaches the predetermined load, a projecting height of the operating button from a surface of a casing is reduced to less than or equal to a predetermined height.

Abstract: An electronic device includes: a backlight holding case 8 accommodating a light guide plate 7; a design frame 3 which includes a flange part 3a protruding inward from a peripheral edge of a frame opening, and a design panel part 3b protruding outward therefrom, and which is attached to an opening of a backlight holding case 8 to sandwich the plate 7 between the flange part 3a and backlight holding case 8; a protective-plate-attached liquid crystal display panel 2 in which a protective plate 2a is mounted on a display surface, and which the outer peripheral part of the protective plate 2a is fixed to the panel part 3b, and the back side is illuminated with light from the light source guided by the plate 7; and a rear side case 4 assembled to the design frame 3 fixed by the panel 2 through the panel part 3b.

Abstract: A mold frame 5 includes a flange part 5b that is formed to expand outward on a peripheral edge of a frame opening, and that holds an outer peripheral part 3b of a protection plate 3 from a rear surface side thereof.
