This will be explained with reference to (b) and (c).

FIGS. 5(a), 5(b), and 5(c) are flowcharts of entry/exit management in FIG. 1.

For example, employee M who is the holder of the IC card 20
They approached the employee's room 34-1c in the figure.

The work process regarding employee M's entry is shown in Figure 5(a).

, (ii) executed as follows.

(i) Password verification process for ID card 20 alone (Figure 5 (
a)) When the user presses the start key in the key switch 21 of the ID card 20 (step 50) and then presses the room entry/exit key, the CPU 25a determines the mode designation according to the program stored in the ROM 25 (step 51);
When the entry/exit mode is selected, the process proceeds to step 52, and when another mode is specified, the process proceeds to other mode processing. In step 52, the CPU 25a determines whether the number of incorrect inputs (NG) of the password is equal to or less than the maximum number of incorrect inputs N (for example, 3 times) stored in a predetermined area of the EEPROM 25d, and determines whether the number of incorrect inputs is NG≦N. If so, the display element 22 displays, for example, the characters "PAAN SHOWODOUZO" as a password input request display (step 53).If N0 times>N,
A message indicating that the card cannot be used is displayed (step 58). When a PIN number (for example, 4 digits "1234") is entered using the key switch 21 according to the PIN input request display (step 54), the CPU 25a inputs the EEP at the time of issuance.

(C)) In Figure 5(b), employee M has verified the ID
The card 20 is placed in the fourth
When inserted into the card reader 3O-1c shown in the figure (step 6
0), after the card reader 30-1c inhales the ID card 20 (step 61), it reads the contents of the OK flag in the ID card 20 (step 62), and when the OK flag ≠ 1, ejects the ID card 20. (Step 69).

When the OK flag = 1, the card reader 30-10 reads the card holder code (for example, a PIN number) (step 63), and reads the holder code via the security controller 31 as indicated by reference numeral 64a. It is transmitted to the lock control computer 40 side in FIG. 5(c) (step 64).

When the CPU 42a on the lock control computer 40 side receives the owner code signal (step 70), the CPU 42a on the lock control computer 40 side reads the ROM 42
According to the program stored in c, it is determined whether or not to permit entry into the room 34-1c (step 71).

When permitting entry, enter the owner code and timer 42d.
ROM the date, time, and permission information = 1
42b (step 72), the response signal is
As shown by reference numeral 73a, it is transmitted to the security controller 31 side in FIG. 5(b) (step 73). CPU
If entry is not permitted in step 71, 42a transmits permission information=O to the security controller 31 via steps 74 and 73.

Upon receiving the response signal (step 65), the security controller 31 on the side of FIG. Then, the door 32-1c is opened (step 67), the N0 count and the 'OK flag in the ID card 20 are set to "0", and the ID card 20 is ejected from the card reader 3O-1c (step 69).

This allows the employee M to remove the ID card 20 from the card reader 3O-1c and enter the employee room 34-1C, after which the door 32-1c automatically closes.

Note that when the permission information≠1 in step 66, the door 3
2-1c does not open and the ID card 20 is inserted into the card reader 32.
-1c.

Note that in the above explanation, the owner code was not described in detail, but it will be described next.

For example, assign a 5-digit number to this as the owner code.

Store this 5-digit number in the EEPROM 25 inside the ID card 20.
d at the time of issuance, and also record the same 5-digit number in the RAM 42b in the lock control computer 40. These 5-digit numbers are then compared by the CPU 42a in the lock control computer 40, and if they match, the identity of the person can be authenticated.The features of this embodiment are particularly as described below. That is, the last digit of this five-digit number is set to, for example, an alphabet.

For example, if the 5-digit number is 3845C, this alphabet (C) indicates the class of the cardholder, and
If the classification of rooms, safes, etc. is also indicated, it will be possible to allow or deny the use of rooms, safes, etc. to ID card holders, resulting in higher-quality access and exit. Able to create a management system.

What should be noted here is that the PIN number and owner code do not necessarily have to match. In the above example, the owner code is 38450, and the password is 3845, which is a four-digit code. If you organize these, the PIN number is 3845 (memory of the ID card 20 holder), the holder code is 3845C (corresponds to the 10 card 20 and the lock control computer 40), the room number is 34-IC, the room door number is 32-IC, and the suffix is as follows: Figure 5 (b
), as shown in step 64.70.71 of (c),
The door 32-1c can be opened or closed.

Based on the above idea, the following modifications are also possible by simply rearranging the logic.

End of card holder number End of number that allows unlocking [) a, b, c b, c Only C In the above explanation, the four digits of the holder code were used as the PIN number, but this holder code For example, an employee number may be used instead. However, at the end of the employee number, a suffix that allows unlocking must be added, such as PIN number 3845 (II) Card 20 holder's memory) Holder code 2538C (employee number 2538). do. It is convenient to classify the last letters into classes as follows: a: president and officer, b: department/section manager, C: section manager and general employee. For example, if a dedicated computer (not shown) for employee management is provided in addition to the lock control computer 40, both computers can be used for independent purposes. It is possible to respond to changes from time to time, such as the hiring of new employees, promotions, etc., without much confusion, as it is only necessary to rewrite the last number.

Next, the card holder's room usage history will be described.

Since the lock control computer 40 is equipped with a timer 42d, when the card holder enters or leaves the room, the ID card 2
The date and time of inserting 0 into the card reader 3O-1a... is C.
It is read by the PU 42a and stored in the RAM 42b, so by inputting the owner code from the keyboard 44, the owner's actions (entry/exit history, usage status of safe, etc.)
can also be displayed on the CRT 45 as a screen or printed by the printer 46. In addition, the lock control computer 40
Since it is also possible to transfer the contents of the RAM 42b and FD 43 in the ID card 20 to the RAM 25b, it is possible to display the memory information on the display element 22 of the ID card 20.

As explained above, in this embodiment, the display ID card 20
By using the , a password (first signal) is input into the ID card 20, and a comment is displayed on the display element 22 of the ID card 20 based on the matching signal (second signal) that is the result of password verification. By transmitting the owner code (third signal) indicating the class classification, the room can be used. Furthermore, R of the lock control computer 40
Recorded contents (fourth signal) in AM42b or FD43
Write it to the RAM 25b in the D card 20 and write it to the I
It is also possible to display the D card 20 alone. Therefore, in addition to rooms, safes, lockers, and other OA equipment, the management of buildings,
For example, it is extremely effective for managing business-related facilities in tenant buildings, as well as facilities on ships and the like. Furthermore, the holder code is not limited to the employee number, and can be replaced with a sports club membership number or the like.

Note that the present invention is not limited to the above embodiments, and various modifications are possible. Examples of such modifications include the following.

■ The LSI 25 of the ID card 20 can be configured with another one-chip or multiple-chip circuit, or can be configured with an EEPROM 25.
d may be configured with other non-volatile memory, or further functions such as a computer function or a timer may be added.

(2) Although the signal exchange means of the ID card 20 is configured by the external terminal 24, it may be configured by a non-contact type means such as a photocoupler method using light or an induction coil method using magnetism.
