摘要： A position detecting apparatus transmits position detecting signals from internal and external transmission coils, which are electrically connected to each other and are wound in opposite directions. The signals are transmitted to a position indicator that is housed within a pen-shaped input member. Since the internal and external transmission coils are wound in opposite directions, the position indicator can be efficiently excited in the entire area of a sensor unit including the end portion thereof. The position indicator receives the position detecting signals and transmits position indicating signals indicating a position. Sensor coils receive the signals from the position indicator. The position detecting apparatus detects the position of the position indicator based on the signals detected by the sensor coils.

摘要： A reference circuit having a variable-impedance function for reducing current consumption is provided. By switching an output impedance of the reference circuit so that the output impedance is large when transmitting a high-frequency signal to a sensor coil, and the output impedance is small when receiving a response signal from the sensor coil, current consumption is reduced. The reference circuit includes a loop gain adjusting circuit having a switch for switching a gain. The magnitude of the output impedance of the reference circuit is switched by opening and closing the switch to switch the gain.

摘要： Methods and apparatus are provided to further facilitate detection not only of a position on a position detector pointed to by a pointing member, but also of information other than the position information such as pen pressure applied to the pointing member, in a position detection apparatus of the electrostatic coupling type. In one embodiment, a pointing member includes a first electrode substantially in the form of a rod, a substantially cylindrical second electrode disposed in such a manner as to surround the first electrode, and a transmission signal production section for producing a signal of a first frequency f1 and another signal of a second frequency f2 different from the first frequency f1 and controlling a phase difference between the signals in response to pressure applied to the pointing member. On a position detector side, the signal of the first frequency f1 is used for position detection of the pointing member, and the phase difference is used for detection of information other than the position information such as pen pressure on the pointing member. Alternatively, a pulse signal having a pulse width corresponding to pressure applied to the pointing member is produced, and on the position detector side, the position, pen pressure and so forth are detected from the pulse signal and the pulse width.

摘要： 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. The position detector further includes a pressure calculation circuit for detecting pressure applied to the pointer, which is associated with the time difference between the two codes, from the result of the correlation matching operation calculated by the correlation matching operation and based on the two codes.
