Abstract
A digitizer includes a tablet and a position indicator. A plurality of loop coils are arranged on the tablet in association with positions. The position indicator has at least a coil on the tablet to generate a predetermined signal in each loop coil. The digitizer also includes a signal detection means and a position determination means. The position determination means selects two adjacent loop coils as a loop coil pair from the loop coil group arranged on the tablet and acquires a "sum" of and a "difference" between signals generated by interaction between the selected loop coil pair and the position indicator. The position determination means determines a position, on the tablet, which is indicated by the postion indicator on the basis of the "sum" of and the "difference" between the acquired signals by the signal detection means.
