Next, the contents of the automatic primary screening in such a structure will be described. First, when the owner of the access card 1 who wants to obtain the access right puts his / her own access card 1 on the magnetic reproducing apparatus 11, the magnetic reproducing apparatus 11 is recorded in the magnetic stripe section 3 in a predetermined format. Read and play the personal information that is stored.

Here, in the magnetic reproducing apparatus 11, information is read by a magnetic head called an "induction type head" as shown in FIG. FIG. 4 is a diagram for explaining the information reproducing mechanism of the magnetic head of the magnetic reproducing apparatus shown in FIG. As shown in FIG. 4, when the medium on which the residual magnetization pattern is recorded is moved close to the tip of the magnetic head 14, the magnetic flux generated by the recording medium changes with time. At this time, magnetic flux 1 flowing into the core of the magnetic head
5 also changes according to the law of electromagnetic induction, a reproduction voltage is generated in the winding 16, and a reproduction signal is obtained. Information is reproduced by electrically processing the reproduction signal.

Next, the magnetic reproducing device 11 transfers the reproduced information to the computer 10. The computer 10 temporarily stores the information transferred from the magnetic reproducing device 11 to the computer 10 in the memory 105 in the computer 10 and confirms that the information from the magnetic reproducing device 11 has been transferred without any problem. Judging from the information, the information necessary for judging the access right is retrieved from the hard disk 109 and extracted. The information to be searched includes cardholder information, past usage information, presence / absence of unauthorized use, presence / absence of card reissue, etc., and the computer 10 determines whether or not to give access right from the searched information.

Although there are various examples of conditions for determining the access right, the following is performed in this embodiment. (1) A person who used an access card with a lost or stolen report (2) A person who illegally used the card in the past (3) A person who was reissued an access card (4) A system administrator Persons who do not recognize access rights (5) Persons who have four passage gates and have blood groups assigned to each passage gate, and the relationship between the blood type of the person and the passage gate does not match (6) Multiple passage gates Persons who do not have a relationship between the birth month of the passerby and the passing gates by assigning even months and odd months to each passing gate (7) Providing multiple passing gates and setting each passing gate to the date of birth Assigned to each month of birth, and the relationship between the month of birth of the passerby and the relationship with the passage gate does not match. (8) Specify the number of times access is valid once an hour, twice a day, and Record the access date and time, and record this (9) Monitor the time from exiting after getting the access right to exiting, and the access right was stripped because the time until exiting was exceeded or the exit did not occur within a certain time. (10) The person who has entered the personal identification number does not match the personal identification number recorded on the access card 1 (11) The person who has expired the access card 1 (12) The person who has entered the date of birth Person whose birth date recorded on the access card 1 does not match (13) The number of times and time interval that can be used for each owner of the access card 1 are limited, and the person who exceeds the limitation, the above judgment condition alone, Or a combination is used to make a determination. When the number of passage gates is increased, the magnetic reproducing device 11 and the display 12 are provided for each passage gate.

When the above-mentioned judgment conditions are met, the computer 10 does not grant the access right to the user of the access card 1, displays “access inaccessible” on the display 12, and instructs the user to undergo the secondary screening. At this time, the door lock of the automatic opening / closing door 13 is left in the locked state.

If the above judgment conditions are not met, the computer 10 grants the card user an access right, displays "access permitted" on the display 12, and unlocks the automatic opening / closing door 13.

Therefore, by performing the above-mentioned automatic primary screening, the access right can be automatically and easily determined for those who desire the access right without any particular problem.

Even if the information recorded on the magnetic stripe portion 3 is destroyed for some reason, the personal information cannot be read out, and the secondary screening is performed.

Next, the contents of the secondary screening will be described with reference to FIG. In the secondary screening, the personal information recorded in the optical recording area 2 of the access card 1 is displayed on the CRT according to the instruction of the inspector, and the inspector permits or disallows the access right based on the displayed information. To judge.

First, when the access card 1 is inserted into the optical recording / reproducing apparatus 21, the optical recording / reproducing apparatus 21 reads and reproduces the personal information recorded in the optical recording area 2 of the access card 1.

In the optical recording / reproducing apparatus 21, information is read / written by the optical head 30 as shown in FIG. FIG. 5 is a diagram for explaining the information reproducing mechanism of the optical head of the optical recording / reproducing apparatus shown in FIG. In FIG. 5, first, the optical head 30 is the optical recording / reproducing device 21.
Control is performed to seek in the optical recording area 2 of the access card 1 in the U or D direction to search for the target information recording track 4. The optical recording / reproducing apparatus 21 can know the position of the light beam spot 31 at the beginning by counting the track crossing signal generated every time the light beam spot 31 crosses the tracking track 5.
The target information recording track 4 can be accurately found. At this time, the autofocus function of the light beam spot 31 is operating, but the autotracking function for scanning the optical head 30 is temporarily stopped.

When the light beam spot 31 reaches the target information recording track 4, the optical recording / reproducing device 21 activates the auto-tracking function of the optical head 30 to move the optical head 30 over the information recording track 4 of the access card 1.
Alternatively, scan in the F direction. At this time, a reproduction signal of information can be obtained from a signal obtained from the reflected light of the light beam, and the personal information is reproduced by electrically processing the reproduction signal.

Next, the optical recording / reproducing device 18 transfers the reproduced personal information to the computer 20. Computer 20
Temporarily stores the personal information from the optical recording / reproducing apparatus 21 in the memory in the computer 20, and
When it is confirmed that the information from the computer has been transferred without any problem, it is necessary to determine the physical characteristics and other personal information and the access right stored in the hard disk in the computer 20 according to the instruction of the inspector input from the keyboard 23. The information and is displayed on the CRT 22. Then, the inspector determines the access right based on the information.

At this time, if there is necessary information, the inspector inputs the information from the keyboard 23 and records the information on the access card 1 by the optical recording / reproducing device 21.
After the secondary screening is completed in the above steps, the inspector returns the access card to the owner, and manually releases the door lock of the automatic opening / closing door 13 when the access right is recognized.

Therefore, even for a person who desires an access right that cannot be obtained by the automatic primary screening, the secondary screening is performed based on a lot of personal information recorded in the optical recording area 2. Since the owner of the access card 1 can be identified with certainty, it is possible to reliably determine the access right.

The collation of fingerprint information, retina information, etc.
Since it can be automatically performed by a collating means (not shown), a system in which an inspector determines whether access is permitted or not based on these collation results may be configured.

Although the computer 10 and the computer 20 may operate in a so-called stand-alone mode, the computer 10 and the computer 20 are connected to a computer network, and the information necessary for determining the access right is retrieved not through the hard disk but through the computer network. The system may be configured.

Further, although the access card 1 used in this embodiment is a composite card having a magnetic stripe portion and an optical recording area, the access card 1 is not limited to the magnetic stripe portion, but a storage element made of a semiconductor chip and an optical recording area. It may be a composite card in which areas are combined.

[0042]

Since the present invention is constructed as described above, it has the following effects.

A method for automatically judging whether or not to permit access by the owner based on the personal information obtained from the first reproducing means for reading and reproducing the personal information recorded in the first recording area. By the screening means No. 1, it is possible to easily determine whether or not to grant access.

Further, when the access is not recognized by the first screening means, the second screening means for displaying more personal information recorded in the second recording area and information necessary for the access determination. As a result, the owner of the card is surely specified, so that it is possible to surely determine whether or not the access is permitted.
