A turntable-type input device includes a base, a first keyboard, a second keyboard and a turntable. The first keyboard and second keyboard are movably disposed on the base. The turntable is rotatably disposed on the base and located above the first keyboard and the second keyboard. The turntable is coupled to the first keyboard and the second keyboard. When the turntable is rotated, the turntable brings the first keyboard and the second keyboard synchronously to move in opposite directions relative to the base such that the first keyboard and the second keyboard are spread out from the base or received to the base.
