ABSTRACT:
In a tablet unit comprising a plurality of X-axis magnetic wires and a plurality of Y-axis magnetic wires arranged on a tablet board in a matrix fashion for detecting an abscissa and an ordinate, respectively, each of the plurality of X-axis and Y-axis magnetic wires is made of an amorphous material. The plurality of X-axis magnetic wires are divided into first through N-th groups. Any one of the X-axis magnetic wires belonging to a particular group is arranged to adjoin two other X-axis magnetic wires belonging to different groups to form a specific combination of three different groups so that those X-axis magnetic wires belonging to the particular group are spaced from one another by at least a predetermined distance and that the specific combination is unique and does not repeatedly appear. The X-axis magnetic wires belonging to each group are connected to one another in series or in parallel. The plurality of Y-axis magnetic wires are utilized in the manner similar to that of the plurality of X-axis magnetic wires. A switching circuit successively and selectively put the plurality of X-axis and Y-axis magnetic wires group by group into the electroconductive state in a predetermined cycle.
