摘要: A digitizer and a method for calculating the position coordinates indicated by indicator on tablet. The has coil that electromagnetically interacts with loop group of signal detection unit, "sum" specifying coordinate determination unit are utilized. sequentially selects two coils as pair from tablet acquires "difference" between signals generated in respective each pair. specifies one pairs which generates maximum absolute value when brought into an interaction state. determines designated indicator, basis specified
