摘要： A pointer detection apparatus is provided, which is capable of detecting a pointed position and a pressure applied by a pointer on a detection sensor. The detection sensor includes a plurality of first conductors disposed in a first direction, a plurality of second conductors disposed in a second direction crossing with the first direction, and a pressure sensitive material disposed between the first and second conductors and having a variable resistance characteristic. When a pointer is positioned in the proximity of (but not in contact with) the detection sensor or when a pressure applied to the detection sensor by the pointer in contact with the detection sensor is equal to or lower than a threshold, detection signals corresponding to variation in electrostatic capacity between the first and second conductors are supplied. When the pressure applied to the detection sensor is higher than the threshold, detection signals corresponding to variation in resistance characteristic of the pressure sensitive material are supplied.

摘要： A pointer detection apparatus includes a conductor pattern formed of intersecting first and second conductors. A signal supplying circuit generates transmission signals each comprised of a first code and a second code having an equal code length and having a predetermined relationship to each other, and supplies the generated transmission signals to the first conductors. A signal detection circuit is connected to the second conductors and detects reception signals, at least one of which corresponds to a variation of capacitance between the conductor pattern and a pointer. A correlation arithmetic operation circuit calculates, for each of the reception signals, first and second correlation values between the reception signal and first and second correlation value arithmetic operation signals corresponding to the first and second codes, respectively. A synthesis circuit calculates, for each pair of the first and second correlation values, a synthesis correlation value, based on which the pointer is detected.
