Abstract: An inputting apparatus of the electromagnetic induction type may provide a transmission signal of a sufficient signal level to a position indicator. A process controlling unit controls a selection circuit on the basis of a reception state of a reception signal received by each of a plurality of electrodes and detected by a reception signal processing circuit such that a first signal for transmitting a transmission signal is supplied to a first electrode at which the reception signal indicates the highest signal level. Further, the process controlling unit controls the selection circuit such that a second signal is supplied to a second electrode at which the signal level of the reception signal is lower than a predetermined signal level. Consequently, signals can be transmitted to a position indicator from both the first electrode, which most receives the signal from the position indicator, and the second electrode spaced from the first electrode.

Abstract: A position detection apparatus of the electrostatic coupling type is provided, to detect not only a position of a pointer but also information other than the position information such as, for example, pointer pressure or side switch information. The pointer transmits two codes such that a pressure applied to a pen tip is associated with a time difference between the two codes. A position detector carries out a correlation matching operation between signals generated in reception conductors and correlation calculation codes corresponding to the two codes, to thereby detect a position on a sensor section pointed to by the pointer from a result of the correlation matching operation and based on at least one of the codes.

Abstract: A position pointer includes a first electrode disposed so as to project from one end portion of a pen-shaped housing in an axial direction; a second electrode disposed in a proximity of the first electrode so as to surround a center axis of the pen-shaped housing; and a signal generation circuit which, in operation, generates a given signal. The signal generated by the signal generation circuit is outputted to a sensor provided in a position detection apparatus. The signal generation circuit, in operation, generates a signal of a first signal level and a signal of a second signal level lower than the first signal level. A signal supply controlling circuit, in operation, selectively supplies the signal of the first signal level and the signal of the second signal level generated by the signal generation circuit to the second electrode.

The at least three electrode pieces are electrically isolated from each other. The position pointer has a signal supply control circuit, which, in operation, controls supply of signals to selectively supply the at least one signal to the second electrode that includes the at least three electrode pieces and to the first electrode.

Abstract: 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.

Abstract: Disclosed herein is an indicator position detecting device that reduces unwanted radiation from a sensor section, while being capable of robustly charging a pen-type position indicator with the sensor section, without requiring reduction in area size of a display region and a detecting region of the sensor section even when the overall device size is reduced. The sensor section has an X-axis direction loop coil group and a Y-axis direction loop coil group disposed in intersecting directions. When a transmission signal is supplied to loop coils of at least one of the X-axis direction loop coil group and the Y-axis direction loop coil group, a control circuit controls a selecting circuit so as not to supply the transmission signal to a determined number of loop coils disposed in at least one peripheral region of the sensor section.
