Next, the operation of the above embodiment will be described with reference to FIGS. 5 (A) to 5 (D). The figure shows the ROM of the controller (20C)
It is a flow chart which shows a traffic control program memorized by (21).

Persons who can pass to the room, which is a specific management area, have their own ID.
The ID stored in the ID card when registering the number
Enter the number and the available time zone into the RAM (22) from the numeric keypad (24) attached to the controller (20C) (S in Fig. 5a).
5A-1, S5A-2). When the registration of all passable persons is completed, the registration operation is ended (S5A-3).

Next, when entering the room, the passer-by causes the card reader (20A) placed outside the room to read the ID card (S5B-1 in FIG. 5 (B)), and confirms the ID number recorded on the ID card. The passable time zone determines whether or not the ID number registered during the registration operation matches the passable time zone (S5B-2),
If they do not match, the NG lamp in the indicator lamp (L20A) provided on the card reader (20A) is temporarily turned on, and then again (S5B-1).
Read the ID card of (S5B-4). If a match is determined, the OK lamp in the display lamp is temporarily turned on (S5B-3), and the unlocking output is output to the electric lock (20D) of the door (D) for a predetermined time through the interface (27) (S5B- Five). As a result, the electric lock (20D) is unlocked for a predetermined time, and the door (D) is opened by turning the knob (k) (S5B-6), (S
5B-7). At this time, the door opening detection sensor (20
E) operates, and the detection signal is transmitted to the CPU (20) via the interface (27) of the controller (20C) (S5B-
8).

When the CPU (20) inputs the detection signal, it is assumed that the person who has read the ID card has entered the room and sets "I" in the flag corresponding to the ID number of the ID card (Fig. 5c,
S5C-1). Next, a card reader (20B) installed in the room
Determines whether or not the ID card has been read, and if it is determined that the ID card has been read, it is determined whether or not the ID number and the passable time of a person corresponding to the ID number match those registered in advance. Yes (S5C-2, S5C-3). At this time, if either the ID number or the passable time does not match, the NG lamp in the display lamp (L20B) is temporarily turned on (S5C-5). If it is determined that only the ID numbers match at the time of matching determination, it is determined whether "I" has already been set in the flag corresponding to the ID number (FIG. 5D, S5D). -1, S5D-
2). This is to detect whether or not a person who leaves the room uses the same ID number to enter the room. As a result, if the ID numbers match, you can exit even if the traffic time is different when you leave, and the OK lamp in the display lamp (L20B) lights up temporarily (Fig. 5C, S5C-4).
An electric unlocking output is output for a predetermined time to the electric lock (20D) of the passage door (D) through the interface (27) (S5C-6).
When the electric lock is unlocked for a predetermined time in response to the unlocking output, the leaving person can turn the knob (k) of the door (D) to open the door and exit the room (S5C-7, S5C-8). When the door opens, the door open detection sensor (20E) operates and outputs a detection signal to the CPU (20) (S5C-9). When the CPU (20) inputs the detection signal, the ID
It is assumed that the person who reads the card has left the room,
Reset the flag corresponding to the ID number to "0". If the determination result of the steps (S5D-1) and (S5D-2) is NO, it is determined that the ID number that is not registered is used and that the room is illegally entered, and the NG in the display lamp (L20B) Turn on the light temporarily (S5D-
3) Then command the reading operation of the ID card again.

The present invention is not limited to the above embodiments, and the same effects can be expected even in the following modes.

The same can be done when the room has two doors.

In addition to magnetic cards, card readers can be used with any ID card other than IC cards and contactless cards.

In addition to card readers, numeric keys, fingerprints, palm shapes, voiceprints, etc.
The ID discrimination device may be used alone or in combination.

The door can be an automatic door or a revolving door.

The traffic conditions are security level other than ID number and time zone (rank to put in the room, and this rank is an emergency switch.
If you turn it ON, you can switch the condition so that only specific people can enter the room). Similarly, if you enter the inside and satisfy the condition, you can let you go out.

The same can be done in a system with many rooms and many card readers (in a large system, data is input from the host computer).

Once you enter the room, you may not go out if the ID number is OK, but you can go out only within a predetermined time. Also, in this case, the exit delay time may be slightly (1
You may allow some time.

〔The invention's effect〕

As described above, according to the present invention, if the specific passage permission condition is satisfied and the entry into the specific management area is permitted,
Since it is possible to exit from the specified management area where entry / exit time is managed based on only the ID determination result when exiting, it is excellent in usability and does not require the troublesome traffic request operation when exiting outside the specified management area outside of the specified management area. There is an effect that it is possible to provide a traffic control device.
