PURPOSE: A mouse for the STAR CRAFT is provided to perform more functions than a conventional mouse by adding some functions to each button of the conventional ball mouse so that a game user may enjoy the STAR CRAFT without using a keyboard. CONSTITUTION: A mouse for the STAR CRAFT comprises a track ball and 3 buttons. Each button has 3 function keys so that the mouse can operate 9 functions. The button comprises one groove(10), other two grooves(11,12), and protrusions(13,14). The groove(10) has contacts(7-9) formed at a proper position of the mouse. The two grooves(11,12), and protrusions(13,14) are formed on an upper and a lower face of the button. In a state that the button is elastically supported by a spring installed at the groove(11), one button can operate 3 functions by switching on/off the contacts(7-9). |
