<p>A coordinates input apparatus has the construction wherein one of the two sense line groupes each disposed along either of X-Y orthogonal coordinates axes is sequentially excited by an excitation circuit (4), a signal processing circuit (5) processes sequentially those induction signals which are induced in the other sense line group (1) when a coordinates indicator having a resonance circuit resonating with the excitation signal is brought close to the sense line, an induction signal memory circuit (7) stores the magnitudes of the processed induction signals and the position of the coordinates indicator (8), or in other words, the coordinates, are determined from the induction signal.</p> |
