[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a seedling entry/removal management system suitable for use in computer rooms of banks, communication companies, etc. This relates to an entry/exit control system that makes it possible to prevent people from being brought into a room.

[Prior Art] Extremely important information is distributed in computer rooms of banks, telecommunications companies, etc. To protect this information from outsiders,
People entering and leaving the facility must be strictly controlled 24 hours a day. For this reason, conventional methods have been used, such as keeping a security guard on duty at all times, assigning a magnetic card or code number to each person entering the room, and opening and closing the door automatically based on input from a card reader or numeric keypad, or a combination of both. Various methods were used.

[Problems to be Solved by the Invention] By the way, under the above-mentioned management system, there are the following problems when goods are brought into and taken out of a computer room.

(1) It is not possible to prevent a person who does not have a magnetic card (mostly a suspicious person) from entering the room accompanied by a person who has a magnetic card.

This is because when the door is opened with a magnetic card, people who do not have the card can also enter the room at the same time.

(2) Even if the security guard determined that the person was suspicious, it was difficult to prevent the person from entering the room if the person was threatened.

The purpose of this invention is to provide an entry/exit management system that solves these problems.

[Means for Solving the Problems] In order to solve the above problems, the present invention includes: a front room leading to another room; a first automatic door separating the front room from the outside;
a second automatic door that partitions the front room and another room; a human body sensor provided in the front room; and a second automatic door that opens the first automatic door only when the front room is unoccupied and the second automatic door is occupied. The present invention is characterized by comprising a control means that permits opening of the door and permits opening of the second automatic door only when the front room is unoccupied and the first automatic door is closed.

[Operation] According to the above means, only when the front room is unoccupied and the second automatic door is closed, the first automatic door opens and it becomes possible to enter the front room from the outside, and the first automatic door opens to allow entry into the front room from the outside. Goods can be brought in. Note that during this time, the second automatic door remains closed.

On the other hand, only when the front room is unoccupied and the first automatic door is closed, the second automatic door opens and it is possible to enter the front room from another room, and items can be carried from the front room to the other room. . During this time, the first automatic door remains closed.

In this way, a state is created in which only the articles exist in the front chamber, and it is through this state that the articles are carried in and out.
It is possible to completely eliminate the risk of a suspicious person breaking into another room.
