<p>PURPOSE:To make the same table available for various kinds of patterns, by arranging the respective loop-form parallel electric conductors so that they overlap the adjacent loop-form parallel electric conductors, respectively, and also providing the logical circuit of the segment coordinate value. CONSTITUTION:The scanning lines x1-xn of the loop-form parallel electric conductor are arranged so that they overlap the adjacent scanning lines. The Y-axis scanning lines are also arranged in the same way. Now, when the detection pen is put on an optional segment on the pattern, the switch 6 operates, and the detection signal detected by the detection coil 4 becomes applicable to many kinds of patterns. Accordingly, when this detection signal is led to the control circuit 8 and the logical signal processing is executed, the position of the selection segment signal can be decided.</p> |
