2. Description of the Related Art There is known an IC card in which an IC (integrated circuit) in which a memory, a processor, a transmission circuit and the like are incorporated is embedded in a plastic card. An IC card has advantages such as a larger storage capacity than a magnetic card and an excellent protection of data because it is strong against a magnetic field. The IC card can transmit and receive data without contact and is used as an ID card for entry / exit management.

An entry / exit management system using an IC card includes a locking / unlocking control device provided at a door of a predetermined entrance and an IC card in which predetermined identification information is written. The user can unlock or lock the door in a non-contact manner by using the access control system. Specifically, when the user turns the transmission unit of the IC card toward the door, the identification information is transmitted from the IC card, the reception unit of the locking / unlocking control device receives the identification information, and the identification information is authenticated. Then, the locking / unlocking mechanism is controlled,
The door is unlocked.

As described above, since the IC card is used in a non-contact type, the possibility of hardware failure is lower than that of a magnetic card or the like. Further, a computer or the like can be connected to the locking / unlocking control device to record and manage the entry / exit status of each individual.

A storage unit 12 connected to the microprocessor 11 for storing identification information and the like, and a modulator 13 for modulating a signal based on the identification information supplied from the microprocessor 11
A local oscillator 14 for providing a predetermined carrier frequency to the modulator 13, a transmitter 6 for transmitting a signal modulated by the modulator 13, and a receiver 5 for receiving a weak electromagnetic wave signal
And a detector 15 for demodulating a signal received by the receiving unit 5.

The storage unit 12 is composed of an EEPROM such as a flash memory, for example.
Stores data indicating identification information of each user. This identification information is also registered in the database on the management side. This identification information can be deleted, changed, or added using a predetermined writer.

As described above, the non-contact type IC storage device 1 also has a function as a wristwatch, and the microprocessor 11 is actually connected to various circuits required for a clock function. ing. Here, a well-known circuit is used for a circuit relating to the clock function, and a description thereof will be omitted.

On the other hand, the locking / unlocking device 20 is a non-contact type
A receiving unit 21 that receives the electromagnetic wave signal transmitted from the transmitting unit 6 of the C storage device 1, a detector 22 that demodulates the signal received by the receiving unit 21, a determination of identification information, control of another block, and an inquiry signal , A lock / unlock mechanism 24 controlled by the microprocessor 23 to lock and unlock the door, and a modulator 2 that modulates an inquiry signal generated by the microprocessor 25.

If the identification information is registered, the microprocessor 23 controls the locking / unlocking mechanism 24 to unlock the door. . This allows the user to pass through this door. Further, the microprocessor 23 controls the locking / unlocking mechanism 24 to automatically lock the door several seconds to ten and several seconds after unlocking.

As described above, the locking / unlocking device 20 is connected to the external terminal 30. External terminal 30
Records the identification information received by the locking / unlocking device 20 and the reception time. Since different identification information is used for each user, it is possible to know which user has passed through the entrance and when the record is left in the external terminal 30. Or for security management of buildings.

As described above, according to the present invention, since the user can wear the non-contact type IC storage device 1 on the wrist, it is not necessary to take out the IC card from the bag every time the user passes through the entrance. And the door can be quickly unlocked.

In this specific example, the locking / unlocking device 2
Although communication between the non-contact type IC storage device 1 and the non-contact type IC storage device 1 is performed by a weak electromagnetic wave, an infrared communication method may be used instead of the electromagnetic wave.

In the above, the present invention has been described using a specific example in which the non-contact type IC storage device to which the present invention is applied is used for an access control system.
The C storage device can be used for various uses other than such an entry / exit management system. For example, the present invention can be applied to any system that can be realized using an IC card, such as passing through a tender gate of public transportation, an entrance of a movie theater, an amusement park, or the like, or adjusting by electronic money.

[0023]

As described above, the non-contact type I according to the present invention is used.
The non-contact I storage device includes a storage unit and a transmission unit.
