The operation of the personal identification device configured as described above will be described separately for the case of registering personal data, the case of re-registering personal data, and the case of performing individual discrimination.

(a) When registering personal data In this case, turn on the registration switch (3) and press the numeric keypad.
Enter the PIN code according to (2). This secret code is encoded by the encoder (9) and added as one input of the coincidence detector (11), and the secret code and personal data memory (10)
Data is applied as the other input of the coincidence detector (11). Here, when the personal identification number input by the ten-key (2) is not stored in the personal identification number memory (10), that is, when the newly input personal identification number is not registered, the coincidence detector (11 ) And the output of the monostable Maltby biflator (14) are both held at the "L" level (the level will be omitted hereinafter), so that the output of the AND circuit (26) is also at the "L" level. In this state, the output of the inverter (18) is kept at "L", so the output of the AND circuit (27) is also "L". Therefore, the buzzer (8) does not ring.

Also, after entering the PIN with the numeric keypad (2),
When the personal data reader (7) is made to read the personal data, the personal identification number and the personal data become the personal identification number and personal data registration device.
Added to (12). On the other hand, when the output of the delay circuit (13) changes to "H" level (the level is omitted below) 1 second after the encoder (9) is set, all the inputs of the AND circuit (23) become "H". It will be PIN code, personal data register
A registration command of "H" is added to (12), whereby the newly input personal identification number and personal data are registered in the personal identification number and personal data memory (10).

Furthermore, the registration signal applied to the OR circuit (30) also becomes "H" due to the registration operation of the personal identification number and the personal data registration device (12), so that the encoder (9) is reset by the output of the OR circuit (31).

On the other hand, if the personal identification number entered with the numeric keypad (2) is already registered in the personal identification data memory (10), the output of the coincidence detector (11) becomes "H" after 1 second required for the coincidence detection. It changes, and the monostable multivibrator (14) outputs a signal of "H" for 5 seconds from this point. During this time,
Buzzer (8) because all inputs of AND circuit (26) become "H"
Will sound for 5 seconds to notify that the personal identification number and personal data cannot be entered. Also, a monostable multivibrator
The output of the inverter (22) becomes "L" because the output of (14) becomes "H", and the outputs of the AND circuit (23) and the OR circuit (28) are both "L". No registration command is added to the personal data register (12). Therefore, the personal identification number and personal data are not registered.

If the buzzer (8) sounds, reset switch
When (6) is turned on, the encoder (9) is reset, so you can start over by entering another PIN using the numeric keypad (2) again.

(b) When re-registering personal data In this case, after turning on the re-registration switch (4), enter the personal identification number using the numeric keypad (2). When this PIN is not registered in the personal data memory (10), the coincidence detector (11) and monostable multivibrator (1
Since the outputs of 4) are all "L", the output of the inverter (21) is "H". Therefore, since all the inputs of the AND circuit (27) become "H", the buzzer (8) sounds for 5 seconds,
Notify that you cannot re-register your personal data. And
Even if both the outputs of the delay circuit (13) and the inverter (18) become "H", the monostable multivibrator (1
Since the output of 4) is "L", AND circuit (24), OR circuit (2
The outputs of 8) are all "L", and no registration command is given to the personal identification number and personal data register (12). That is, registration of personal data is blocked.

If the buzzer (8) sounds, the reset switch
When (6) is turned on, the encoder (9) is reset. Therefore, the numeric keypad (2) is used again to input another secret code, that is, a secret code which has been registered in advance.

On the other hand, if the personal identification number entered by the ten-key (2) is registered in the personal identification data memory (10), the output of the coincidence detector (11) changes to "H" and the monostable multivibrator (14) outputs "H" signal for 5 seconds only. Since the output of the inverter (21) is kept at "L" during this period, the output of the AND circuit (27) is also "L". Therefore, the buzzer (8) does not ring.

When the personal data reader (7) is made to read the personal data after the personal identification number is input, the personal identification number and the personal data are added to the personal identification number and the personal data registration device (12). At this time, since the output of the monostable multivibrator (14) is "H", the inputs of the AND circuit (24) are all "H", and the personal identification number and personal data register ( A registration command of "H" is added to 12). Therefore, the previously registered personal identification number and new personal data corresponding to the personal identification number are re-registered in the personal identification number and personal data memory (10).

Furthermore, the encoder (9) is reset by the personal identification number and the registration signal of the personal data register (12).

(c) In the case of individual discrimination In this case, after turning on the discrimination switch (5), the personal identification number is input by the ten-key (2) and the personal data is input by the personal data reader (7).

Here, if the entered personal identification number is not in the personal identification data memory (10), as described above, the coincidence detector (11)
Is "L", and the output of the monostable multivibrator (14) is also "L". Therefore, the output of the AND circuit (25) is held at "L" and the unlock signal is not output. This is nothing other than the fact that it was determined to be improper, and the door does not open.

Next, the entered PIN is PIN and personal data memory
If it is in (10), the output signal of the coincidence detector (11) changes to "H", and the monostable multivibrator (14) outputs a signal which becomes "H" only for 5 seconds. And encoder (9)
Is also applied to the coincidence detector (15). Therefore, the coincidence detector (15) is based on the coded personal identification number output from the encoder (9), the personal identification number, the personal data in the personal data memory (10), and the personal data reader (7).
The personal data input via the above is compared, and if both match, an "H" signal is output, and if both do not match, an "L" signal is continuously output. Where the match detector
When (15) outputs the "H" signal, the monostable multivibrator (16) outputs the "H" signal only for 5 seconds.

Thus, when the entered personal identification number is in the personal identification number and personal data memory (10) and the entered personal data matches the personal identification number and personal data in the personal data memory (10).
Since all the inputs of the AND circuit (25) become "H" level, the unlock signal is output and the door is opened, and the encoder (9) is reset by this unlock signal. Even if the entered personal identification number is in the personal identification number and personal data memory (10), the entered personal data is
When it does not match the personal data of (0), the output of the monostable multivibrator (16) does not become "H", and therefore the unlock signal is not output.

The present invention has been described above with reference to the preferred embodiments. However, in addition to a fingerprint or a palm print as a personal data reader, for example, a hand type,
Voice, eyes, etc. may be read, or a so-called ID (Identification ca
rd) The card number may be read as personal data.

Further, in the above-mentioned embodiment, the personal identification number is input by using the ten-key pad, but the same operation as described above can be performed by using a device for inputting by voice instead.

Further, in the above embodiment, the personal data cannot be registered or re-registered when the same number is already registered when the personal identification number is input and when the personal identification number input when re-registering the personal data is not registered. Although the buzzer was used to notify the effect, instead of this, a display with a lamp, a cathode ray tube (CRT) display, a light emitting diode (LED) or a liquid crystal (LC
Any notifying means such as a display using D) or a device for guiding by voice may be used.

Further, although three switches are provided for registration, re-registration and discrimination of personal data in the above embodiment, rotary switches may be used instead of these switches for switching.

Further, in the above-mentioned embodiment, the operation switch, the numeric keypad, the personal data reader, etc. are installed on the upper part of the box, but the position may be on the front part, the side part, or in some cases, the lower part.

Although the personal data is registered and blocked by the logic circuit in the above-mentioned embodiment, it goes without saying that all the functions such as coincidence detection and monostable multivibrator may be processed by the microcomputer.

[Effects of the Invention] As described above, according to the present invention, when the personal identification number and the personal data are registered, whether or not the input personal identification number has been registered is detected by the coincidence detecting means, and the personal identification number has already been registered. For example, the registration blocking means prevents registration of the personal data and the notification means notifies that the registration cannot be performed. Therefore, the management of the personal identification number for preventing the deterioration of the individual discrimination ability becomes unnecessary, and the user's favorite It has the effect that a number can be selected.
