  • Coordinate input device with flat cable having two divided flat mounting parts composing divided conductor portions
    Patent number: 6304251
    Abstract: A coordinate input device is disclosed wherein first lead-out electrode portions formed on a lower substrate and second lead-out electrode portions formed on a film substrate are connected to conductor portions, respectively, of a flat cable and are thereby drawn out to the exterior. Therefore, unlike the prior art which requires that third lead-out electrode portions formed on a film substrate be connected to second lead-out electrode portions formed on a lower substrate with use of an electrically conductive adhesive, it is not necessary to do so. Thus, the connecting operation is easy and the coordinate input device of the present invention is superior in productivity and less expensive.
