MOUSE

摘要

PROBLEM TO BE SOLVED: To provide a mouse for preventing dusts from intruding in a simple structure. SOLUTION: A ball part 3 moves on a desk face 8 so that mouse moving amounts can be transmitted. A difference in level 4 is formed so that dusts can be prevented from intruding. A groove 2 is formed so that the dusts can be stored. A roller part 5 is formed so that the mouse moving amounts can be detected. A rubber part 6 is formed so that the dusts can be removed by rubber adhesion preventing materials. An optical sensor 7 is formed so that the removed dusts can be detected.
