摘要： An inquiry device in the conventional non-contact IC card system has a problem that the electronic circuit size is large and complicated, requiring a very expensive high frequency part to increase the cost. In order to solve this problem, a part of the signal processing function realized by an electronic circuit in an inquiry device is performed by a receiving antenna and a receiving high frequency amplifier, thereby significantly reducing the electronic circuit size. The inquiry device includes a carrier oscillator connected to a transmitting mixer, a receiver section, and a receiving high frequency amplifier for amplifying the receiving high frequency received by the receiver section. The inquiry device in the non-contact IC card system is characterized in that a carrier generated by the carrier oscillator is interference-input to the receiving high frequency amplifier so as to modulate the receiving high frequency. As compared to the conventional method, the power distributor and the frequency converter can be omitted.

摘要： In the conventional non-contact passive (power-source-less) IC card system method, a self-oscillator is built in a responder. The self-oscillator changes its oscillation frequency by the fluctuation of the power source voltage. Accordingly, it has been difficult to perform time management in the circuit in the responder. In order to solve this problem, in a carrier signal (micro wave) transmitted from an interrogator, the information to be transmitted is multiplexed by a clock frequency component reproduced by the responder. Upon reception of this, the responder extracts the clock frequency component from the modulated wave multiplexed and oscillates a stable frequency clock according to that component. Thus, it is possible to eliminate the problem that the information transfer rate of the circuit signal from the responder to the interrogator fluctuates according to the distance between the interrogator and the responder.
