Abstract
A position detecting device and a position pointing device therefor transmit information concerning the position pointing device or an operator from a cordless position pointing device to a tablet. An AC field containing information about the position pointing device or the operator and a write instruction is transmitted to the position pointing device by an instruction source of the tablet. The information is stored in a memory of the position pointing device by an instruction extractor responsive to a controller of the position pointing device. The stored information is read out to a characteristic controller in response to an AC field containing a read instruction received by the device from the tablet.
