An electronic device includes a main body, an input device, a latching mechanism, at least one first driving device, and at least one support mechanism. The main body includes a housing defining a recess therein. The input device is rotatably received in the recess and rotatable between a first position where a top surface of the input device is substantially coplanar with a top surface of the housing, and a second position where the input device is inclined with respect to the top surface of the housing. The latching mechanism is configured to latch the input device in the first position. The first driving device is configured to rotate the input device to the second position when the input device is released by the latching mechanism. The support mechanism is configured to support the input device, thereby maintaining the input device in the second position.
