DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safe deposit box system using an integrated multifunctional key comprising an electric storage means and a metal key, and more particularly, to identification of a safe user in the electric storage means. Store information and use the safe provided that the stored identification information matches the pre-registered information, and that at least the keyhole provided in the safe and the metal key match. Related to a safe deposit box system.

[0002]

2. Description of the Related Art A safe deposit box system is usually installed in a bank, a shinkin bank, a securities company, or the like, and is provided for use.
Generally used for storing important documents, seals, precious metals, etc.
Therefore, banks that provide safety deposit boxes need to be very thorough in security and reliability. On the other hand, from the viewpoint of customers who use safe deposit boxes, safe deposit boxes can be provided by simpler procedures and simplified operations. Desirably available.

[0003] One generation ago, the safety box was accompanied by a staff member guiding the customer to a safe box. This is a method in which a customer submits a request for opening a warehouse, in which predetermined items are filled in and stamped, to a bank, and after confirming the identity by verifying the seal on the bank side, an attendant guides the customer to a safe deposit box. The safety box is provided with two sets of locks, one for the bank and one for the user, and simultaneously operates the bank key and the customer key to open the safe door and quit the use while attending. And again,
It locks the safe with both keys in the presence of a customer.

[0004] The conventional safe deposit box was operated in the above-described manner, so that a certain level of security could be ensured. However, since the safe deposit box and clerk seats are usually separated from each other, the safe deposit box is not used. It was not possible to constantly monitor abnormal conditions such as destruction and unauthorized use, and it was difficult to say that security was perfect. In addition, a staff member must accompany each customer, and since the use status of the safe is managed in accordance with a handwritten request for opening a warehouse, there is a problem that the business efficiency of the bank is poor. In addition, customers must bring their seal and key each time they use the safety deposit box and open the store.
There was a problem that the use procedure was complicated and troublesome.

[0005] Therefore, an unmanned system of a safe deposit box which eliminates the disadvantages of the conventional safe box described above has been proposed and put into practical use. This unmanned safe deposit box system issues a safe deposit card composed of a magnetic card and a customer key to a customer, and operates using these. The safe deposit system is
Basically, it is constructed by a card reader for entry, a card reader for reception, and a center control unit. A front room is provided in the front of the safe deposit box, and the front room and the outside are separated by a front room door. The entrance card reader is arranged outside the front room door, and the customer causes the entrance card reader to read the safe deposit card, opens the front room door, and enters the front room.

[0006] A reception card reader is installed in the front room, and the customer inserts the safe deposit card into the reception card reader again, and further inputs a personal identification number. When the personal identification is performed by the safe deposit card and the personal identification number, an embossed copy of the safe deposit card is taken by the imprinter. When the procedure for accepting the use of the safe box is completed, the customer moves from the front room to the safe room and opens the corresponding safe box with the customer key. Each lending safe is provided with a bank lock and a customer lock, and the bank lock is already unlocked by the center control unit described later when the identity is verified by the information read by the reception card reader and the entered password. Locked. When the use is over, close the safe deposit door and leave the safe deposit box.

The center control unit is installed in a bank office or the like, and includes a CPU, a CRT display, a keyboard, a storage device, a printer, and the like. The center control unit is connected to a card reader for entry, a card reader for reception, a front room door, and a bank lock provided in each safe box, and controls each connected device and performs entry / exit management. ing. The entry / exit management is management of the number of users, the user name, the use time, and the like. Based on such information, a bank clerk enters the safe deposit box as needed.

[0008] The above-mentioned unmanned safe deposit box system is perfect in terms of security because only persons having a safe deposit card are allowed to enter the safe deposit box. Since entry / exit can be managed by the processing, labor saving and efficiency improvement of the business in the bank can be achieved at the same time. Also, if the user brings the safe deposit card and the customer key, the user can use the safe deposit by a relatively simple procedure, which is excellent in convenience.

[0009]

However, in the above-mentioned unmanned safe deposit box system, if the user cancels the use contract of the safe deposit box, the issued safe deposit card and customer key are collected. In this situation, it is possible to illegally open and close a safe using a forged magnetic card and a duplicated customer key. For this reason, it is desirable that the cylinder portion of the safety deposit box after the cancellation of the use contract be replaced to ensure safety, and there is a problem that the maintenance cost increases in this respect.

Further, the magnetic card has an inherent property that the stored content is easily destroyed by the influence of external magnetism and has low mechanical strength when a bending force is applied. I can't say. Further, the magnetic card has an overwhelmingly small storage capacity as compared with an electric storage means such as a ROM or the like, has poor expandability for uses other than for personal identification, and is virtually impossible to reuse. Furthermore, there is a problem that it takes a certain amount of time to issue, and it is hard to say that it is ideal as a medium used in a safe deposit box system.

From the standpoint of the user, when using the safe deposit box, the user must always bring both the safe deposit card and the customer key, and many users still feel troublesome. In addition, please use a safe deposit card,
The customer key must be properly used depending on the location and location, and this is not always satisfactory from the viewpoint of simplicity of operation of the safe deposit box.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and an electronic storage means and a metal key are integrally formed in place of a magnetic card and a customer lock conventionally used. It is intended to provide a safety deposit box system using a multifunction key.

[0013]

[0014]

A multi-function key is issued to a user of the safe deposit box , key identification information is attached to the surface of the multi-function key, and the user identification information of the user is written in the electric storage means. When using the safety box, the user enters the multifunction key with the entry control device usually installed outside the safety box to bring the multifunction key and enter the safe box. The entry control device determines whether entry into the safe deposit box is permitted based on the user identification information stored in the electrical storage means of the inserted multifunction key. If it is determined that entry into the room is permitted, the entry door is opened and closed for a certain period of time.

[0015] The user who has entered the safe deposit box next inserts the multifunction key brought again into the reception device. In the accepting device, the user identification information stored in the electric storage means is read, and it is determined whether the read user identification information matches information registered in advance in the system controller. If they match, a use permission signal is output from the system controller, and the corresponding safe deposit box can be used. At the same time,
The use recording means provided in the reception device is a table of multifunction keys.
The key identification information attached to the surface is imaged, and this is used as a usage record.
And hold.
