Abstract
A portable electronic device, which has a slidingly attached touch screen (DPL ) and a sliding lid (SL ) also slidingly installed on top of the touch screen. A keyboard (KB ) is installed on top of the sliding lid. In a normal state, the display of the device is partly covered by the sliding lid and, thus, protected by the sliding lid against mechanical stress. When necessary, the display can be revealed by moving the sliding lid away from the display, whereupon a cogging (R ) made on the bottom of the sliding lid rotates a cogwheel (CW ), attached inside the device, that touches the cogging. The cogwheel transmits the movement of the sliding lid to a movement that is opposite to that of the sliding lid of the display, through a gear rack R attached to the display. Correspondingly, the device can again be brought to the normal state by moving the sliding lid back on top of the display or the display to underneath the sliding lid, whereupon the cogged surfaces that touch against each other cause the remaining moving element to move, and again bring the device to the normal state.
