Abstract:
A coordinate input device comprising:a lower substrate having a first transparent resistance film formed on one side thereof;a pair of first electrode portions formed on said first transparent resistance film, said paired first electrode portions being parallel to each other and forming a first operation area;a pair of first lead-out electrode portions formed on said first transparent resistance film, said paired first lead-out electrode portions being drawn out respectively from said paired first electrode portions and being adjacent to each other and spaced apart at end portions thereof;an upper transparent film substrate having a second transparent resistance film formed on a lower side thereof;a pair of second electrode portions formed on said second transparent resistance film, said paired second electrode portions being parallel to each other and forming a second operation area;a pair of second lead-out electrode portions formed on said second transparent resistance film, said paired second lead-out portions being drawn out respectively from said paired second electrode portions and being adjacent to each other and spaced apart at end portions thereof;a flat cable having conductor portions, the conductor portions paired and correspondingly connected with said paired first lead-out electrode portions and said paired second lead-out electrode portions;said paired first lead-out electrode portions and said paired second leadout electrode portions being arranged to be adjacent and spaced apart to each other as viewed from a direction looking through said lower substrate and said upper transparent film substrate when said upper and lower substrate are overlapped;said paired conductor portions for said pair of first lead-out electrode portions and said paired conductor portions for said pair of second lead-out electrode portions being arranged adjacent to each other and spaced apart at said conductor portions of said flat cable;wherein said lower substrate and said film substrate are combined together in an opposed state of said first and second transparent resistance films to each other, and end portions of said paired first lead-out electrode portions and end portions of said paired second lead-out electrode portions are connected respectively to said conductor portions of said flat cable while each of the pair of end portions is adjacent to each other;wherein a mounting portion having a flat surface of said flat cable is provided with a slit in an end portion thereof to constitute first and second divided mounting portions, said paired conductor portions positioned in the first divided mounting portion are connected to said paired first lead-out electrode portions on the lower substrate, while said paired conductor portions positioned in the second divided mounting portion are connected to said paired second lead-out electrode portions on the upper substrate.
