Coordinates input device
First Claim
1. In a coordinates input device including first collecting electrodes disposed at both edges of a first resistive film and parallel to each other, second collecting electrodes disposed at both edges of a second resistive film and parallel to each other, said first and second resistive films being disposed opposite to each other with said first and second collecting electrodes meeting at right angles to each other, and plural auxiliary electrodes disposed on said first and second resistive films and parallel to said respective first and second collecting electrodes, said coordinates input device comprising:
- an unusable region disposed between said first or second collecting electrode and the respective auxiliary electrode disposed adjacent thereto.
