Abstract: A joystick device includes a base, an upright joystick handle disposed pivotally on the base and operable to generate a first input signal, and a mouse unit disposed on a top end of the joystick handle and operable to generate a second input signal. An output unit is disposed on the base. A control unit is disposed on the base and connected to the joystick handle, the mouse unit, and the output unit. When the joystick handle is operated, the control unit receives the first input signal from the joystick handle so as to output a first output signal via the output unit. When the mouse unit is operated, the control unit receives the second input signal from the mouse unit so as to output a second output signal via the output unit. A power source supplies electric power to the control unit.
