1. An information input/output system comprising:
an indication operation device; and
an information processing device including a sensor,
wherein the indication operation device includes:
a core body,
a pressure detector that, in operation, detects a pressure applied to a tip of the core body,
a first electrode,
a second electrode,
a signal generation circuit which, in operation, generates a signal to be transmitted to the information processing device,
a first transmission circuit which, in operation, transmits the signal from the signal generation circuit to the sensor of the information processing device through the first electrode or the second electrode,
a reception circuit which, in operation, receives information from the information processing device through the first electrode or the second electrode,
an information storage device which, in operation, stores the information received by the reception circuit, and
a transmitter that is different from the first electrode and the second electrode, wherein the transmitter, in operation, transmits pressure information corresponding to the pressure detected by the pressure detector and the information stored in the information storage device to an outside of the indication operation device, and
the information processing device includes:
a processor which, in operation, processes the signal received from the indication operation device through the sensor,
an acquisition circuit which, in operation, acquires information corresponding to a result of processing performed by the processor, and
a second transmission circuit which, in operation, transmits the information acquired by the acquisition circuit to the indication operation device through the sensor.
