摘要： The present invention relates to a foldable keyboard comprising a left base plate, a right base plate, and a link shaft. Each of the base plates has a side pivotally connecting to the link shaft, enabling the base plates to expand and fold. The invention is characterized in that a first keypad secured on the left base plate; a second keypad glidingly mounted on the right base plate, and at least a linkage mechanism with a first pivot joint, a second pivot joint, and a third pivot joint; whereby the first, second, and third pivot joints are pivotally connected to the left base plate, the link shaft, and the second keypad respectively, allowing the linkage mechanism to pull the second keypad close to the first keypad when the left and right base plates are expanded horizontally; and when the left and right base plates are folded, the linkage mechanism pushes the second keypad away from the first keypad.
