Next, the operation of this embodiment will be explained in terms of setting entry/exit conditions, normal entry, normal exit, abnormal entry (bringing), abnormality release processing, report function, and other functions.

(1) Setting room entry/exit conditions When the device is started or when the room entry/exit conditions are changed, the main controller 50 transmits information such as room entry/exit conditions to the terminals 38 and 39. Terminal 38,3
The control unit C of 9 stores this information, and thereafter controls the opening and closing of each door based on the stored information until a change is made from the main controller 50. In addition,
When the main controller 50 stops operating due to a failure or the like, the terminals 38 and 39 are designed to perform independent control.

(2) Normal entry A person with the correct magnetic card can enter the computer room 23 by following the steps below. Note that data such as a recitation number and name are magnetically recorded on this magnetic card.

Entering the front room 22 In the elevator hall 21, present the magnetic card to the card reader 26,
When you enter the recitation number from the numeric keypad 26a,
The control section C of the terminal 39 checks whether the conditions match. When the conditions match, the automatic door 24 is opened to permit entry, and the data read from the magnetic card is transmitted to the CPU 58. Note that if the conditions do not match three times in a row, the cards are collected.

Pass through check-in gate 30 and enter computer room 23.

Enter the front room 22a through the automatic door 24,
Card reader 33 of check-in gate 30
Terminal 38
The control unit C checks whether the conditions match. If the conditions match, the control section C opens the door of the check-in gate 30 through the door control section D and permits entry into the gate 30. And the human 37 central detection sensor 3, 4,
8, 9 (light is blocked), the door 35 is closed and the door 36 is opened, and the exit sensor 6, 12
The door 36 is closed when one second has elapsed after passing through. When the user enters the front room 22b from the front room 22a and reaches the automatic door 25, the automatic door 25 is opened by an infrared sensor (not shown), allowing entry into the computer room 23.

Note that when the check-in gate 30 is successfully passed, data to that effect is transferred to the main controller 50 and stored.

(3) Normal exit A person with the correct magnetic card can exit the computer room 23 by following the steps below.

From the computer room 23 to the front room 22b.

When the person leaving the room stands in front of the automatic door 25 in the computer room 23, the automatic door 25 is opened by the infrared sensor and the person is permitted to enter the front room 22b.

Passing check-in gate 30.

When a magnetic card is presented to the card reader 34 in the front room 22b, the control section C of the terminal 38 checks whether the conditions match or do not match. When the conditions match, the door 36 is opened, and thereafter, when the person passes the central detection sensors 3, 4, 8, and 9, the door 36 is closed and the door 35 is opened, and when the person passes the exit sensors 1 and 11, the door 35 is opened. When seconds have elapsed, the door 35 is closed. In this way, it is possible to exit from the front chamber 22b to the front chamber 22a. If the conditions do not match, the magnetic card is requested to be re-presented, and if the conditions do not match three times in a row, the card is collected and an abnormality processing is performed. These data are then sent to the main controller 50 as room occupancy management information.

From the front room 22a to the elevator hall 21.

In the front room 22a, the magnetic card is presented to the card reader 27, and when the conditions match, the automatic door 24 opens and the user can exit to the elevator hall 21.

(4) Abnormal Entry (Enterprise) If an abnormal approach to the check-in gate 30 occurs, that is, entrapment, the situation will be as shown in FIGS. 5a and 5b, and the following processing will be performed.

(a) In the case of Figure 5 a, the light shielding of central detection sensors 3, 4, 8, and 9 is 2
When this is repeated, the control unit C of the terminal 38 determines that entrainment has occurred and notifies the main control device 50. As a result, the main controller 50 issues commands to the terminals 39 and 40,
Automatic doors 24 and 25 are closed. Further, an alarm is output from the alarm unit A (FIG. 3) and a buzzer is sounded in the computer room 23. Furthermore, the main controller 50 records abnormalities and outputs a warning.

In this way, the two people shown in FIG. 5a are trapped in the front room 22, and this state is maintained until a security guard or the like performs an abnormality release process.

(b) In the case of Figure 5b When the lower detection sensors 2 and 5 are simultaneously shielded from light (the black dots 2 and 5 in Figure 5b indicate a shielded state), it is determined that entrainment has occurred, and the same situation as above occurs. The process is carried out, and the two people shown in the figure are confined in the front room 22.

Note that when leaving the room, the same process as above is performed, and the automatic doors 24 and 25 are closed and an alarm is output.

(5) Abnormality Release Process When the front chamber 22 is blocked due to the above-mentioned abnormal entry, it becomes impossible to enter or leave the computer room 23. Therefore, it is necessary to perform an operation to release this, which is performed in the following steps.

A magnetic card usually carried by security guards (a special code is recorded on this card)
while presenting it to the card reader 26,
The automatic door 24 opens by inputting the recited code from the numeric keypad 26a. However, the abnormality has not been resolved yet.

Next, after confirming the occurrence of the abnormality, when the security guard's magnetic card is presented to the card reader 33, the control unit C of the terminal 38 resets the check-in gate 30 and sends a signal to the main controller 50. As a result, the main controller 50 resets the terminals 39 and 40, stops the buzzer, and records that the abnormality has been cleared.

(6) Report function When a magnetic card is presented to the card reader 26, 27, 33, or 34, or when a command is input from the keyboard 57 in Fig. 4,
The following record is output from the CRT display device 54 or printer 56.

(a) When you present your magnetic card.

A: Month, day, hour, minute, day of the week B: I/D number, name C: Door number D: Normal (conditions matched) or abnormal (conditions mismatched) E: Reason for abnormality (b) From the keyboard 57 Online report by directive.

B: Computer room 2 at specified time and by department.
Outputs the number of people in room 3.

B: Search/display whether or not someone is in the room by entering their name or name code.

C: Report output of usage status by entry/exit time.

D: Report/display of entry/exit status for each designated individual.

(7) Other functions (a) All doors are unlocked and each door is locked/unlocked by inputting a command from the keyboard 57 of the main controller 50 or by operating a manual switch (not shown).

(b) Monitoring of locked/unlocked status.

A door opening/closing indicator 56 displays the opening/closing of each door with a lamp.

(c) Setting the time period during which unlocking is prohibited.

By inputting commands from the keyboard 57,
You can set times when entry is prohibited.

(d) All doors are forced open by a fire signal. This ensures the safety of those inside the computer room.

Note that the following may be considered as a modification of the above embodiment.

(1) In addition to the above, methods for detecting entrapment include phototubes, infrared sensors,
It is possible to use ITV or a combination of these.

(2) As the check-in gate, a rotating type used at amusement parks, hotel entrances, etc. may be used.

(3) As a pass, in addition to the above-mentioned magnetic card and recitation number, a neighborhood card, an ID card, or a combination of recitation number and various cards can be used.

(4) Magnetic recording devices (magnetic tapes and floppy disks) in computer rooms are weak to magnetism, so
By adding a magnetic detection device to the check-in gate, it is possible to prevent anyone holding a magnet from entering the room.

(4) By changing the reading level of magnetic cards, it is possible to prevent the use of fraudulent cards and strengthen access control.

〔Effect of the invention〕

As explained above, the present invention includes an anteroom leading to a separate room, a partition that divides the anteroom into two and prevents passage to the separate room, and a check-in gate provided so as to penetrate through the partition. The check-in gate is equipped with an information reader that reads information entered by the person entering the room.
A control unit is provided that opens and closes the automatic door provided at the entrance to the front room based on the information read by the information reader, and a sensor that detects the passage of a person entering the room is installed in the direction of travel of the passage of the check-in gate. Since a plurality of them are provided at predetermined intervals, the following effects are achieved.

(1) There is no need for security guards to enter and exit the room, allowing unattended management. Therefore, labor saving can be achieved.

(2) Computer rooms and other facilities are often open 24 hours a day, which increases personnel costs for security guards, but by making them unmanned, personnel costs can be significantly reduced.

(3) With conventional security guards, it is not possible to completely control entry and exit when the security guard is not present (for emergencies, late at night, etc.), but mechanization makes it possible to maintain complete control at all times.

(4) Partitions and check-in gates can completely prevent people from being dragged into the room.

In addition, the front room is provided with a first automatic door leading to the outside and a second automatic door leading to the separate room, and when the check-in gate detects abnormal entry such as bringing someone into the room, the first and second automatic doors open to the outside. Since the automatic door is closed, the following effects can be achieved.

(5) It is possible to prevent suspicious persons from entering the computer room and preventing suspicious persons from escaping.

(6) Since a suspicious person can be confined in the front room, the safety of the general public (people in the computer room and people outside) can be ensured.

Furthermore, since a recording means is provided for recording information input by the person entering the room who has successfully passed through the check-in gate, the following effects can be obtained. (7) Since entry and exit records can be recorded for each individual, it is possible to check for people who are behaving suspiciously.

(8) It is possible to instantly know who is in the computer room. As a result, it is possible to quickly check whether there are any people left in the computer room after the work is completed, allowing for more detailed operations.
