Input device having coordinate-inputting unit and switching unit
First Claim
1. An input device comprising:
- a face sheet;
coordinate-inputting means opposing a lower portion of the face sheet; and
switching means opposing a lower portion of the coordinate-inputting means, wherein the face sheet, the coordinate-inputting means, and the switching means are laminated in a thickness direction;
the coordinate-inputting means comprises a plurality of X-direction electrodes and Y-direction electrodes opposing each other and arranged on both surfaces of a base sheet in a grid manner;
the switching means comprises a substrate having a plurality of switch contact portions in a grid arrangement, the switch contact portions being switched by the inversion of invertible plates; and
projections are disposed between the coordinate-inputting means and the invertible plates.

Abstract
An input device is provided. The input device contains a face sheet, coordinate-inputting means opposing the lower portion of the face sheet, and switching means opposing the lower portion of the coordinate-inputting means. The face sheet, the coordinate-inputting means, and the switching means are laminated in a thickness direction. The coordinate-inputting means has X- and Y-direction electrodes opposing each other and arranged on both surfaces of a base sheet in a grid manner. The switching means has a substrate with a switch contact portions in a grid arrangement. The switch contact portions are switched by the inversion of invertible plates. Projections are disposed between the coordinate-inputting means and the invertible plates.
