  Therefore, the security function of the electronic ID card can be easily used.

  Furthermore, by operating the operation unit, it becomes possible to exhibit substantially the same function as a conventional keyless entry system, and the convenience of using the authentication system based on ID information is good.

  FIG. 1 shows an intelligent key system of the best mode for carrying out the present invention and a portable device using the intelligent key system.

  The same or equivalent parts as those in the conventional example will be described with the same reference numerals.

  First, in terms of configuration, in the intelligent key system of the best mode, as shown in FIG. 1, an in-vehicle device 10 mounted on a vehicle 1 is connected to an antenna unit 11 used for normal vehicle communication. Yes.

  The in-vehicle device 10 is provided with an ID signal processing unit 12.

  The ID signal processing unit 12 collates the contents of the ID information of the received signal received by the antenna unit 11, and if it matches the registered ID information, the door lock control unit or the engine control unit 5 An authentication signal for permitting locking / unlocking and engine starting is transmitted.

  On the other hand, an electronic ID card 6 composed of an ID card such as an IC license has an IC chip 7 incorporated therein. This IC chip is configured to hold unique ID information and to communicate this ID information with the ID card storage type portable device 13 via a card side proximity antenna (not shown). Has been.

  Further, the ID card storage type portable device 13 is provided with a concave storage portion 13a so that the electronic ID card 6 can be attached and detached.

  As shown in FIG. 1, when the electronic ID card 6 is stored and mounted in the storage unit 13a, the ID information of the electronic ID card 6 is placed at a position facing the card-side proximity antenna. A proximity antenna unit 14 is provided as a readable reading means.

Furthermore, in this ID card storage type portable device 13, it is connected to the proximity antenna unit 14,
An operation unit 15 is provided as information processing means for processing the read ID information so as to be able to communicate via the portable antenna unit 17 as communication means.

  In the calculation unit 15, the processed control signal is sent to the portable device main control unit 16.

  In this portable machine main control unit 16, the portable antenna unit 17 used in a normal vehicle controls a transmission / reception unit 18 to be connected and a processed control signal sent from the calculation unit 15. It is mainly comprised by the part 19 and the operation part 20 which has a pushbutton switch etc. which are used for a keyless entry function.

  When the portable side antenna unit 17 receives the LF signal from the vehicle 1 when the vehicle is accessed, in the ID card storage type portable device 13, the proximity antenna unit 14 The ID information is read from the electronic ID card 6 that is close or inserted.
