PEN, SENSOR DEVICE, AND PEN SYSTEM

WIPO Patent Application WO/2019/215857

A1

[Problem] To reduce the shortage of communication resources which can be used for communication between a pen and a sensor device. [Solution] This pen for supplying an internal digital value NA of N bits to a sensor device includes an integrated circuit 27 that acquires a series of internal digital values NA on the basis of the state OPS of a pen pressure detection unit 23. The integrated circuit 27 supplies a first internal digital value NA to the sensor device by transmitting, through an antenna 22, first transmission data MF which includes a first reference digital value MS corresponding to the first internal digital value NA, and supplies a second internal digital value NA to the sensor device by transmitting, through the antenna 22, second transmission data MF of less than N bits which includes a relative digital value MR of M bits (M
