Position indicator, position detecting device, position detecting circuit, and position detecting method
First Claim
1. A position indicator, comprising:
- a housing; and
circuitry, which, in operation, transmits a plurality of signal blocks to a position detecting device, each of the signal blocks sized to include a defined number of bits and including;
a part of first information, out of a plurality of divided parts of the first information, the first information represented as a digital signal comprised of a number of bits that is greater than the defined number of bits corresponding to a size of each of the signal blocks,wherein the position indicator, in operation, transmits the plurality of divided parts of the first information by transmitting the plurality of signal blocks.

Abstract
A position indicator includes a housing and circuitry. The circuitry transmits a plurality of signal blocks successively to a position detecting device. Each of the signal blocks includes a position detection signal, a first modulated signal acquired by modulating one part of a plurality of divided parts of position indicator identification information, and a second modulated signal acquired by modulating current position indicator status information acquired successively from a signal supplied to a control terminal or from a voltage state of the control terminal. The position indicator transmits the plurality of divided parts of position indicator identification information by transmitting the plurality of signal blocks.
