  • Patent number: 5541370
    Abstract: A writing pad having a construction wherein two substrates each having electrodes formed on one of the surfaces are disposed in parallel in such a way that their electrodes face one another with a predetermined gap between them. The gap is defined by insulating dot spacers fixed at regular intervals to at least one of the electrode surfaces. The height G of the dot spacers is smaller than 15 .mu.m, the average center distance L between the adjacent dot spacers is smaller than 100 .mu.m, d>G and 3 d<L<100 d (where d is a diameter of the dot spacers on the electrode surface to which the dot spacers are fixed). According to this writing pad, when characters or graphics are inputted to the input substrate of the writing pad by an input pen, an erroneous input does not occur even when fingers, etc., erroneously come into contact with the input substrate, and the erroneous operation does not occur, either, when the input operation is repeated many times by the input pen.
