Abstract
A coordinate input device includes a columnar operation member and a printed circuit board to which the operation member is mounted on a major surface thereof. The printed circuit board includes a deformation part which can be deformed when the operation member is tilted or depressed. Deformation detecting elements disposed on one major surface or the other major surface of the deformation part determine the amount of deformation of the deformation part. A substrate such as used in a known coordinate input device is eliminated from the operation member so that the number of components is reduced and the coordinate input device is easily manufactured.
Claims9
A coordinate input device comprising:
- a columnar operation member;
- a printed circuit board which is provided with the operation member mounted to one major surface thereof and which includes a deformation part which is deformable when the operation member is tilted or depressed;
- and
- at least one deformation detecting element provided on the deformation part, for determining the amount of deformation of the deformation part.
