<p>PURPOSE:To display only the component in the coordinate direction or the component in the a Y coordinate direction by providing an X coordinate switch and a Y coordinate switch or a select switch and selecting the component of a moving amount in the X coordinate direction or in the Y coordinate direction sent from a ball part by combining those switches with a selector. CONSTITUTION:This device is provided with a ball part 1 to detect the component of the moving amount caused by rotation in the X coordinate direction or in the Y coordinate direction while being rotated in any arbitrary direction and to transmit a track ball signal, left and right switches 2 and 3 to respectively designate the execution of specified functions by being pressed, X coordinate switch 4 to instruct the selection of the component of the moving amount at the ball part 1 in the X coordinate direction, Y coordinate switch 5 to instruct the selection of the component in the Y coordinate direction. Further, a selector 6 is provided to transmit the component of the coordinate direction, which moving amount is designated, while inputting signals from the X coordinate switch 4 or the Y coordinate switch 5.</p> |
