An electronic machine, a display apparatus and a communication apparatus are provided which are capable of minimizing an increase in the dimensions of an apparatus body which is ascribed to the improvement of the controllability of the apparatus and an increase in the sizes of a display screen. A case unit is pivotably joined to an apparatus body by a pivot, and an upper operating element of a cross key and function keys are provided so that these parts are positioned on the axis of the pivot. Thus, an operating force occurring when the upper operating element and function keys are operated is exerted on the axis of the pivot.
