In a keyboard input device, a first input device and a second input device each including a stick pointer are arranged. An input control of gesture functions such as zoom-in, zoom-out, right rotation, left rotation, forward tracking, backward tracking, left tracking, right tracking, and the like may be made possible by a combination of operational directions of operation bodies of the stick pointer (SP1) of the first input device and the stick pointer (SP2) of the second input device.
