Abstract: A flap actuation mechanism is provided with flaps for opening an aperture formed in the housing of a notebook sized personal computer. A first shaft portion and a second shaft portion rotatably support rotating plates bent and formed in the flaps and an insertion mouth is formed in the abutting surfaces of the flaps. An opening pin is inserted into the insertion mouth from the outside. The positions of the first shaft portion and the second shaft portion are set according to the height of the rotating plates so that the moment of rotation for opening the flap outside the housing is greater than the moment of rotation for rotating the flap inside the housing. With this, it becomes possible to reduce the height of the rotating plates and therefore the flap actuation mechanism can be made thin.
