Positioning indicator and position indication method
First Claim
1. A method of establishing bi-directional communication between a position indicator and a position detector including a tablet sensor, the position indicator having a power supply and configured to transmit a signal from a tip portion of an elongate body of the position indicator, the method comprising:
- transmitting a first signal, which is generated based on the power supply, from the tip portion to indicate a first position of the position indicator relative to the tablet sensor;
receiving, at the position indicator, a command transmitted from the position detector; and
in response to the command, transmitting a second signal, which is generated based on the power supply, from the tip portion to indicate a second position of the position indicator relative to the tablet sensor different from the first position,wherein the command includes a request indicating what type of information the position indicator is requested to transmit to the position detector.

Abstract
A position indicator is provided, which includes a pressure sensor configured to detect a pressure applied to a tip of the position indicator. The position indicator further includes a storage configured to store the pressure as one type of digital data and to store at least one other type of digital data. The position indicator also includes a receiver configured to receive a command signal transmitted from a position sensor, and a control circuit configured to select one or more types of digital data in the storage based on the command signal. The position indicator includes a transmitter configured to transmit the selected one or more types of digital data to the position sensor.

8. A pen-shaped position indicator for use with a position detector including a tablet sensor, comprising:
-
a power supply; a signal generating oscillation circuit; an elongate body having a tip end and a proximal end; a first coil configuration provided at the tip end and configured to transmit a first signal generated by the signal generating oscillation circuit driven by the power supply, to indicate a first position of the position indicator relative to the tablet sensor; a second coil configuration provided at the tip end and configured to control transmission of a second signal generated by the signal generating oscillation circuit driven by the power supply, to indicate a second position of the position indicator relative to the tablet sensor different from the first position; and a control circuit configured to control the transmitting of the second signal based on control of the second coil configuration in response to a command received from the position detector, wherein the command includes a request indicating what type of information the position indicator is requested to transmit to the position detector. - View Dependent Claims (9, 10, 11, 12, 13, 14)
