<p>PURPOSE:To detect coordinates even at the end part of a tablet and to expand the effective area of coordinate detection by correcting the operation value of a position in a pitch when a indicator is included in the end part area. CONSTITUTION:At the time of detecting coordinates, an area deciding means always decides whether the indicator is included in the end part area or not, and when the indicator is not included in the area, outputs the detected coordinate value as it is. When the indicator is included in the area is decided, the operation value of the position in the pitch of a conductor is corrected by a correction value through a correcting means and the coordinate value calculated by the corrected value is outputted as a detected coordinate value. Consequently, coordinate detection can be attained even at the end part of the tablet and the effective area of the coordinate detection can be expanded.</p> |
