2. Description of the Related Art Conventionally, as a card type information recording medium,
Various types such as magnetic cards, IC cards, and optical cards are known. A magnetic card has a magnetic recording unit for magnetically recording and reproducing information, and has a recording capacity of about several tens of bytes.
It is widely used because of its low price and easy to use. However, magnetic cards have become a social problem because of their low security and easy forgery. For this reason, IC cards with high security have attracted attention in recent years. In general, an IC card has an IC section containing a CPU, a ROM, a RAM, and an electrically erasable EEPROM, and can electrically record and reproduce information. Normally, the recording capacity of an IC card is about 8 kbytes, and the price is higher than that of a magnetic card. However, since the security is extremely high, it is expected that the IC card will be widely used in the future.

On the other hand, an optical card has an optical recording section for optically recording and reproducing information and is a write-once recording medium on which recorded information cannot be erased, but the recording capacity of the optical card is as large as several megabytes and the price is high. Due to the relatively low cost, a wide range of applications is envisaged. Recently, an optical recording unit and a CPU for optically recording and reproducing information, focusing on the size of the recording capacity of an optical card and the security of an IC card,
An optical / IC card having a ROM, a RAM, and an IC unit containing an electrically erasable EEPROM has also been developed.

16 is a data input / output terminal, and 13 and 17 are unused terminals. In an IC card information recording / reproducing apparatus that records or reproduces information on an IC card, when recording information on the IC unit 7, the recording is performed by serially transferring the information via the data input / output terminal 16 of the IC unit 7. When reproducing information from the IC unit 7, the data input / output terminal 16 of the IC unit 7 is used.
Reproduction is performed by serially receiving information via the.

Next, an entry / exit management system as one application example using an IC card will be described with reference to FIG. 10 and FIG. FIG. 10 is a diagram showing information of the IC unit 7. The IC unit 7 includes a CPU, a ROM, a RAM,

To 2 are provided.

[0007] The file 1 records personal information (ID information and the like) of the card owner. The information of the file 2 will be described later. On the other hand, a file 3 is provided in the IC information recording area, and the file 3 records history information such as a date, a time when the card owner releases the key, and a place where the card is entered and exited. The history information of the entry / exit of the file 2 is about several tens of bytes. In the file 2 of the IC information management area, size information of the history information recorded in the file 3 is recorded. The access right is set for each file, and the IC card information recording / reproducing device can release the access right for each file.
Can be played.

Next, the operation of the entry / exit management system using the IC card as a key for entering / exiting the room will be described with reference to FIG. In FIG. 11, first, it is monitored that a card is inserted into the IC card information recording / reproducing apparatus (S
1) When the card is inserted into the device, the personal information of the file 1 shown in FIG. 10 is reproduced (S2). Next, it is determined whether or not the personal information has been normally reproduced (S3). If the personal information has not been reproduced normally, the card is ejected (S9) and waiting for the next card to be inserted. .
On the other hand, when the personal information can be normally reproduced, the reproduced personal information is compared with the personal information registered in the system in advance (S4), and it is determined whether the card owner is permitted to enter and leave (S5). ).

Here, if the personal information does not match and entry / exit is not permitted, the card is ejected (S9).
Wait for the next card to be inserted. When the personal information matches and entry / exit is permitted, history information on the current entry / exit is additionally recorded in the history information of the file 2 shown in FIG. 10 (S6), and whether or not the history information has been normally recorded It is determined whether it is (S7). If the history information could not be recorded normally, the card is ejected (S9) and the system waits for the next card to be inserted. When the history information can be normally recorded, the key is released (S8), and the card is ejected (S8).
9) Wait for the next card to be inserted. The cardholder who is allowed to enter and exit in this way is
When an IC card is inserted into the C card information recording / reproducing device,
The entry / exit history is recorded on the IC card and can pass through the door.

[0010]

However, in the above-mentioned conventional system, when recording / reproducing information on / from the IC card, communication is performed by connecting the IC section to the terminal of the apparatus. Or the terminal of the device cannot be normally connected to the IC unit due to contamination of the terminal of the IC unit or the like. Therefore, there has been a problem that information on the IC card cannot be recorded and reproduced, and even a card owner permitted to enter and exit cannot enter and exit.

In addition to a contact type in which information is recorded and reproduced by contacting a terminal like an IC portion of an IC card, a non-contact type IC card in which communication is performed by electromagnetic waves to record and reproduce information, There is also known an optical communication type IC card or the like that performs optical communication using an optical emitter and an optical receiver to record and reproduce information. However, in such a non-contact type IC card, in a place where strong electromagnetic waves are generated, such as under a high-voltage wire, communication between the device and the IC unit may be disabled due to the influence. As described above, communication failure occurs in both the contact type and the non-contact type IC card, and the system may not be operated.

An object of the present invention is to provide a card system capable of reducing the probability of being unable to communicate with a recording medium and stably operating it in view of the above conventional problems.
