Mobile communication apparatus

The present invention discloses a mobile communication apparatus that includes a first casing and a second casing. The first casing has an opening and an operating interface disposed around the opening of a side of the first casing. The second casing has two display screens disposed separately on two corresponding surfaces thereof, and each display screen separately corresponds to a different program module of the mobile communication apparatus. The second casing is pivotally disposed in the opening, such that the second casing can be spun in the opening. If the second casing is turned over to expose a display screen with the operating interface, the mobile communication apparatus then initiates the program module corresponding to said screen display, and said screen display shows messages outputted by the program module.
