Claims

[Claims for Utility Model Registration] (1) A sphere that rolls in any direction on a plane; a roller that is a rotating body with a smaller diameter than the sphere and that rotates forward and backward in response to the rolling of the sphere; A roller that supports the roller so that the rotating surface of the roller is brought into contact with the surface of the spherical body, and the central axis of rotation of the roller always follows parallel to an arbitrary central axis of rotation perpendicular to an arbitrary rotating direction of the spherical body. A mouse comprising a support mechanism, a rotation speed reading sensor that detects the rotation speed of the sphere from the rotation speed of the roller, and a direction detection sensor that detects the rotation direction of the sphere from the orientation of the roller. (2) The roller has a plurality of light reflectors arranged at equal intervals on the rotating surface along the rotating direction,
The rotation speed reading sensor includes a light emitting element that irradiates light onto the rotating surface of the roller via a light emitting fiber optic cable that is open at both ends, and a light emitting element that irradiates light onto the rotating surface of the roller via a light receiving optical fiber cable that is open at both ends. 2. The mouse according to claim 1, further comprising a light receiving element that receives reflected light from the mouse. (3) The roller has a plurality of magnetic bodies arranged at equal intervals on the rotating surface along the rotation direction, and the rotation speed reading sensor includes a magnetic detection element that detects passage of the magnetic body. The mouse according to claim 1, characterized in that the mouse has: (4) The direction detection sensor includes a slit disk that rotates forward and backward according to the roller support posture of the roller support mechanism, and a photo interrupter that optically detects the amount of rotation of the slit disk in the forward and reverse directions. The mouse according to claim 1, characterized in that: (5) Claim 1 characterized in that the direction detection sensor has a rotation volume whose output changes according to the roller support posture of the roller support mechanism.
The mouse described.
