Abstract
An IC tag includes: an antenna that receives a modulation signal in which a pause period, during which a carrier wave is interrupted, is intermittently present in a carrier wave signal; a clock signal extraction circuit that extracts, as a clock signal from the modulation signal received by antenna, a signal attained by binarizing the carrier wave included in the signal; a demodulation circuit that detects the received modulation signal to generate a binary detection signal; a control circuit that, during reception mode, restores a command data piece from the detection signal in synchronization with the clock signal and performs a process based on the command data piece; and a reset circuit unit that supplies, to the control circuit, a pause reset signal prompting a reset upon detecting the pause period in received modulation signal when the circuit is in a state other than the reception mode.
