Claims (1)

[Scope of utility model registration request] A thin wire type abscissa tablet and an ordinate tablet are made by arranging multiple conductive thin wires in parallel on one side of an elastic insulating plate, and press-fitting a resistor through which a current is passed orthogonally to one end of the thin wire. In a character/figure input device that overlaps each other with a pressure-sensitive conductive spacer in between so that the directions of the thin wires are perpendicular to each other and presses on an elastic insulating plate to detect a voltage indicating the coordinates of the pressed point, each doublet thin wire A character/figure input device characterized in that a group of thin lines selected from every other side of a surface is connected to an area detection resistor, and the remaining groups of thin lines are connected to a thin line detection resistor.
