    • The invention relates to a mobile communication device, with a casing and a keypad comprising a plurality of keys and a plurality of rotatable key elements comprising a protrusion. Each key element is adapted to depress a first key in a first direction, when rotated in a first rotating direction, and depress a second key in said first direction, when rotated in a second rotating direction. Each key element is adapted to be rotated in said first rotating direction upon application of a force onto the protrusion in a second direction. Each key element is adapted to be rotated in said second rotating direction upon application of a force onto the protrusion in a third direction. The second and third direction is opposite to each other, and the first direction is perpendicular to said second and said third direction.
    • 本发明涉及一种移动通信设备,其具有包括多个键的壳体和键盘以及包括突起的多个可旋转键元件。 每个键元件适于当沿第一旋转方向旋转时按第一方向按压第一键,并且当沿第二旋转方向旋转时,按所述第一方向按下第二键。 每个键元件适于在沿第二方向施加到突起上的力时沿所述第一旋转方向旋转。 每个键元件适于在沿着第三方向施加到突起上的力时沿所述第二旋转方向旋转。 第二方向和第三方向彼此相反,并且第一方向垂直于所述第二方向和所述第三方向。
