<p>PROBLEM TO BE SOLVED: To provide a mechanical mouse hardly causing malfunctions even when dust is stuck to the ball of the mechanical mouse. SOLUTION: This mouse is provided with a mechanism for detecting the movement of the mechanical mouse from a rotation amount detector 13 for detecting the rotation amount of a primary shaft 11 passed through the ball 10 and a moving angle detector 22 for detecting an angle formed by a primary bearing 12 for supporting the primary shaft 11 and a secondary bearing 22 connected to the primary shaft 11 at the center part of the primary bearing 12 by a secondary shaft 20 provided with the angle of 90 degrees. Also, for the ball 10, a contact point part with the primary shaft 11 is plane worked so as to secure a distance with the primary bearing 12.</p> |
