Opening/closing mechanism
 An opening/closing mechanism is used in apparatus such as personal computers, word processors and liquid-crystal televisions, some of these apparatus. The opening/closing mechanism comprises: a base (10) attached to a main body (20) of an apparatus; an arm (18) attached to an opening/closing portion (21) of the apparatus and axially supported on the base (10) so as to turn freely; a rotary plate (12, 13) which turns together with the arm (18) and which has a projection (13d); a pop-up plate (14) having an engaging portion (14b, 14c), wherein when the opening/closing portion (21) is closed up to a prescribed position, the engaging portion, (14c) engages with the projection (13d) of the rotary plate so that the pop-up plate turns together with the rotary plate (13); and a resilient member (19) provided between the pop-up plate (14) and the base (10) and compressed by turning of the pop-up plate (14), wherein when the opening/closing portion (21 ) is released, the rotary plate (13) is turned together with the pop-up plate (14) by a compressive reaction force, thereby opening/closing portion (21) up to a prescribed position.
