<p>PROBLEM TO BE SOLVED: To provide a mouse which is cordless, does not have a battery nor a ball and is highly operable. SOLUTION: When electromagnetic coupling between a high frequency resonance circuit mounted on a computer mouse and a grid coil equipped with a mouse pad 2 changes with the position of the mouse 1, the relative moving quantity of the mouse 1 is detected by utilizing a phenomenon in which the impedance of the grid coil changes. A means for receiving the self-oscillation of a mouse resonance circuit with the mouse pad 2 and a means for changing a self-oscillation frequency with the type of a mouse button transmit mouse button information to the mouse pad 2. The two means realizes the cordless mouse that does not have a ball nor a battery.</p> |
