The card-side loop antenna 52 is formed by wiring an Al pattern on a printed wiring board by, for example, a technique such as etching.

(Communication method)
Next, a basic communication method of the communication system 10 according to the first embodiment will be described.

(Connection between electrostatic coupling side reader / writer unit 29 and electrostatic coupling type IC card 40)
The conductive members 32A and 32B of the electrostatic coupling-side reader / writer unit 29 and the conductive plates 42A and 42B of the electrostatic coupling IC card 40 are formed by facing the conductive members 32A and 32B and the conductive plates 42A and 42B to each other. The two are connected in a non-contact manner by an electrostatic coupling method, and information can be transmitted.
The first IC chip 41 included in the electrostatic coupling IC card is capable of electromagnetic induction communication standardized to any one of ISO / IEC14443, 15693, and 18092. The signal frequency is 13.56 MHz for communication. Is used.
In this case, in the circuit of the reader / writer 21, a signal having a resonance frequency is generated by the R / W loop antenna 21a. Since the reader / writer 21 is connected by the R / W loop antenna 21a, the AC signal generated by the reader / writer 21 is efficiently transmitted to the R / W loop antenna 21a and the conductive members 32A and 32B.

When the conductive plates 42A and 42B approach the conductive members 32A and 32B, the conductive members 32A and 32B and the conductive plates 42A and 42B are electrostatically coupled, and the AC signal generated by the reader / writer 21 is connected to the conductive plates 42A and 42B. The first IC chip 41 obtains drive power. Further, transmission data from the communication device 20 can be transmitted to the first IC chip 41, while return data from the first IC chip 41 can be transmitted to the communication device 20.
In this way, the control unit 27 communicates with the first IC chip 41 of the electrostatic coupling IC card 40 by electrostatically coupling the pair of conductive members 32A and 32B to the pair of conductive plates 42A and 42B. Process.

(Connection between electromagnetic induction side reader / writer 28 and electromagnetic induction type IC card 50)
The R / W loop antenna 21a of the electromagnetic induction side reader / writer unit 28 and the card side loop antenna 52 of the electromagnetic induction type IC card 50 are connected in a non-contact manner by the electromagnetic induction type, and can transmit and receive information. The communication system of the electromagnetic induction system IC card 50 is standardized by ISO / IEC 14443, 15693, 18092, and a signal frequency of 13.56 MHz is used.
In addition, although the number of turns of the R / W loop antenna 21a and the card-side loop antenna 52 has been described as being about 3 turns, it is not limited thereto. What is necessary is just the number of turns by which both are connected non-contactingly by an electromagnetic induction system, and the number of turns should just be 1 or more turns, for example.

An electromotive force is generated when the card-side loop antenna 52 approaches the R / W loop antenna 21 a, and the driving power is transmitted to the second IC chip 51. Further, transmission data from the communication device 20 can be transmitted to the second IC chip 51, while return data from the second IC chip 51 can be transmitted to the communication device 20.
In this way, the control unit 27 communicates with the second IC chip 51 of the electromagnetic induction IC card 50 by the R / W loop antenna 21a communicating with the card-side loop antenna 52 by the electromagnetic induction method. Perform communication processing. In this case, the communicable distance is, for example, about several tens of mm.

(Simultaneous communication between the electrostatic coupling side reader / writer unit 29 and the electrostatic coupling type IC card 40 and between the electromagnetic induction side reader / writer unit 28 and the electromagnetic induction type IC card 50)
The R / W loop antenna 21a of the electromagnetic induction side reader / writer unit 28 and the conductive members 32A and 32B of the electrostatic coupling side reader / writer unit 29 are arranged at positions that do not overlap when viewed from the vertical direction Z. Therefore, the control unit 27 performs communication processing with the first IC chip 41 of the electrostatic coupling IC card 40 by electrostatically coupling the pair of conductive members 32A and 32B to the pair of conductive plates 42A and 42B. And the R / W loop antenna 21a communicates with the second IC chip 51 of the electromagnetic induction IC card 50 by communicating with the card-side loop antenna 52 by the electromagnetic induction method. Either communication process can be executed, or both communication processes can be executed at the same time.

  Here, “to execute both communication processes at the same time” means that both the electromagnetic induction IC card 50 and the electrostatic coupling IC card 40 are brought close to the communication device 20 and the communication process is executed at the same time. Means that. In other words, in the communication between the communication device 20 and the electromagnetic induction IC card 50 and between the communication device 20 and the electrostatic coupling IC card 40, for example, the timing at which both communication processes are executed is complete. Need not coincide with each other as long as the communication process is executed at the same time. In this case, the control unit 27 is preferably provided with an anti-collision function for avoiding collision of these pieces of information.

  As described above, the communication system 10 is connected between the control unit 27 of the communication device 20 and the second IC chip 51 of the electromagnetic induction IC card 50 and between the control unit 27 of the communication device 20 and the electrostatic coupling IC card 40. Communication processing can be performed with the 1 IC chip 41.

As described above, the communication system 10 of the present embodiment has the following effects.
(1) The conductive members 32A and 32B of the communication device 20 and the conductive plates 42A and 42B of the electrostatic coupling IC card 40 face each other and are electrostatically coupled, whereby the communication device 20 and the electrostatic coupling IC card 40 are A signal can be transmitted to and from the first IC chip 41.
In addition, the electrostatic coupling IC card 40 does not include an antenna, and has a simple and small structure including only the conductive plates 42A and 42B, and thus can be manufactured at low cost. For this reason, as the number of issued electrostatic coupling IC cards 40 increases, the cost becomes more advantageous, and the system can be constructed at a low cost.

(2) Since electromagnetic induction communication devices that are widely distributed in the market can be diverted, a system can be constructed easily and at low cost.
Even when a new electrostatic coupling system is introduced, an IC chip used for an electromagnetic induction IC card can be used, and an existing non-contact IC reader / writer can be used. As a result, a system can be constructed without the need to newly develop a special IC chip for electrostatic coupling and a communication device of electrostatic coupling type.

(3) Even when a new electrostatic coupling system is introduced, the R / W loop antenna 21a and the card-side loop antenna 52 of the electromagnetic induction IC card 50 perform electromagnetic induction, whereby the communication device 20 Can be communicated by a conventional electromagnetic induction IC card 50. As a result, any one of the electrostatic coupling IC card 40 and the conventional electromagnetic induction IC card 50 can be used. Therefore, when a new electrostatic coupling system is introduced, the conventional electromagnetic induction IC card 50 can be used, and the conventional system can be changed smoothly.

(4) Communication can be performed at the same time between the electromagnetic induction side reader / writer unit 28 and the electromagnetic induction type IC card 50 and between the electrostatic coupling side reader / writer unit 29 and the electrostatic coupling type IC card 40.
Further, in the communication device 20, the R / W loop antenna 21a and the conductive members 32A and 32B have different configurations. Therefore, compared with a conventional system that can read two conventional electromagnetic induction type IC cards in a stacked manner, the two IC cards can be read without being stacked. For this reason, by making it communicate without overlapping two IC cards, the fall of the transmission efficiency at the time of communicating with two IC cards at the same time can be suppressed, and efficient and stable communication can be performed.
