Claims

[Scope of utility model registration request]

A code plate having position detection information is fixed to a shaft that contacts a rotatable sphere, the shaft is rotatably supported by a case, and rotation of the sphere is transmitted to the code plate via the shaft. In the coordinate input device, a bearing fixed to a case near the code plate and rotatably supporting the shaft includes a slider slidingly in contact with the pattern of the code plate, and a slider attached to the slider. A coordinate input device characterized by being provided with a contact that connects directly to a pattern on a conductive circuit board.
