  The present invention relates to an IC card unauthorized extraction preventing system in an IC card reader / writer that prevents an IC card inserted from an IC card insertion port of an IC card reader / writer from being illegally extracted by a third party.

2. Description of the Related Art Conventionally, an IC card reader / writer is provided with an IC card insertion slot for inserting and inserting an IC card, and when a user reads data stored in the IC card, the user inserts the IC card into the IC card insertion slot. The IC card reader / writer is set so that it can be read from and written to the IC card, and after the various processing by the IC card is completed, the IC card is removed from the IC card insertion slot.
Usually, since an IC card set in an IC card reader / writer is in a state in which the IC card can be removed from the IC card insertion slot even if it is a third party, the IC card reader / writer is not a valid user of the IC card. Since the three parties can easily remove the IC card from the IC card reader / writer, there is a risk that the IC card may be illegally extracted and stolen by a third party at any time.

In recent years, card systems using these IC cards and IC card reader / writers have been used in various industries and various applications. Usually, an IC card user inserts an IC card into the IC card reader / writer. In such a state, the user may temporarily leave the place from where the IC card reader / writer is installed.
However, there is a risk that a third party illegally pulls out the IC card from the IC card reader / writer, steals it, and performs an illegal act with the stolen IC card during such leaving.

For example, when an ETC system is used for highway settlement, for example, a credit IC card may be always inserted into an in-vehicle reader / writer and set in operation.
In such a case, if it is suitable for damage such as vandalism, the credit IC card set in the in-vehicle reader / writer can be easily removed from the in-vehicle reader / writer and stolen.
This is because anybody can easily remove the IC card from the IC card reader / writer.

As a conventional technique for performing personal authentication, for example, fingerprint data registered in an ID card and fingerprint data read from the ID card holder are compared and collated. Technology for confirming whether or not the user is a legitimate person who can use the ID card is known. (For example, see Patent Document 1)
However, in the conventional known technology, since the IC card can be removed from the IC card reader / writer, the IC card set in the IC card reader / writer can be prevented from being stolen by a third party. Can not.
