ABSTRACT:
A foldable keyboard for inputting data into a portable electronic device is provided. The foldable keyboard includes an upper cover, a lower cover, a first keyboard portion, and a second keyboard portion. A space is formed, as the upper and the lower cover are in closed relationship to each other, for accommodating the first and second keyboard portions. As the upper and lower covers are opened from the closed relationship and the second keyboard portion, relative to the first keyboard portion, is rotated pivotally, said first and second keyboard portions are allowed to be substantially on a common plane.
