ABSTRACT:
A mouse has a ball, a rotation detecting section for detecting the rotation of the ball, and a casing for containing the ball and the rotation detecting section. A hole is formed at a position on the upper surface of the casing directly above the ball, and covered with a transparent acrylic plate. This structure allows the operator to make certain, during operation, that the ball is smoothly rotating. The ball is placed offset toward the leading end of the mouse.
