<p>PURPOSE:To provide a highly unctional keyboard switch provided with the track ball which actualizes corresponding track ball operation by the combinational operation of keys of a keyboard. CONSTITUTION:The keyboard switch 1, a keyboard arithmetic part 3, the track ball 2, and a track ball arithmetic part 4 are provided, and the keyboard arithmetic part 3 and track ball arithmetic part 4 are connected to each other by a track ball control signal line 8 for transmitting control signals mutually. A corresponding track ball control signal is outputted to this track ball control signal line 8 by specific predetermined key operation on the keyboard, and the track ball arithmetic part 4 outputs a movement signal corresponding to the track ball control signal to a main body 7 by considering that the track ball 2 is virtually moved, and obtains a corresponding movement distance by the combinational operation of keys.</p> |
