The electronic device 100 comprises a housing 110, an input device 120, a sliding groove 130 and an actuating unit 140. The input device 120 is disposed on the housing 110. The input device 120 includes a first input interface 121 and a second input interface 122, while the first input interface 121 and the second input interface 122 are respectively disposed on opposite surfaces of the input device 120. The sliding groove 130 is formed on the housing 110. The actuating unit 140 is connected to the input device 120, and the actuating unit 140 moves automatically between a first position 131 and a second position 132 of the sliding groove 130 to rotate the input device 120. When the actuating unit 140 is in the first position 131, the first input interface 121 faces outward from the housing 110. When the actuating unit 140 is in the second position 132, the second input interface 122 faces outward from the housing 110 (reference FIGS. 2A ̃2D, which show the rotation of the input device 120).
In the first embodiment above, the first input interface 121 includes a keyboard, and the second input interface 122 includes a handwriting recognition device. In the first embodiment of the invention, the actuating unit 140 moves automatically to push and to rotate the input device 120. The input device 120 is therefore rotated automatically to exchange the positions of the first and second input interfaces. Thus, the dimensions of the electronic device can be further reduced.
