Abstract
This invention is concerned with a character recognition device which includes a writing pad having a pair of sheets with one of the sheets comprising an area of high resistivity and the other one of the sheets comprising a layer of conductive material, the sheets being normally electrically insulated from one another but adapted to be brought into contact with one another by application of writing pressure by a writing implement upon the writing pad, the sheets being adapted to be connected to an electrical switching circuit whereby current is caused to flow through the pad along two alternate paths, wherein the high resistivity and the conductive sheet are separated by a layer of reticulated material and the conductive material is sufficiently elastomeric to provide good continuous electrical contact between the sheets when writing pressure is applied.
