Description

  The present invention is for centrally storing and managing digital keys used by a user in order to unlock a plurality of doors, and is equipped with the digital key and having a personal authentication means It is about the box.

Conventionally, for example, in an office, a key that can be opened and closed for each storage is stored in a digital key box, and the user can open and close the door of the digital key box by ID authentication such as an ID card. I borrowed a key and used it. The digital key box opens the door only when the user is authenticated by the ID card and the person has the right to access the storage.
However, in order to check the documents in a large number of vaults one by one, it was necessary to move with a lot of keys, and the workability was poor. In order to solve the problem, a system capable of opening and closing a plurality of storages using the same single key has been desired.

A master key is known as a system capable of opening and closing a plurality of storages using the same key. The master key can open and close all storages, but it is for emergency situations such as when the key is lost.If the master key is used on a daily basis, a different lock must be placed in the storage. The meaning of installing and managing is lost. Also, the right to access for each storage cannot be set for each person.
On the other hand, what makes it possible to set a storage that can be opened and closed with a single key by replacing the cylinder lock for each storage using a cylinder lock that is easy to replace is commercially available. According to this, the storage which can be opened and closed with the same one key can be arbitrarily set and changed.

On the other hand, there is a technique described in Patent Document 1 as a technique combining an IC tag and a key. In Patent Document 1, a contact IC tag is incorporated in a key gripping part, and data of the contact IC tag is read out by a door side data terminal that contacts a key data terminal exposed at a part of the gripping part. It is disclosed that when the data is not registered in ID, the solenoid is prevented from rotating.
The key is a normal key and can be opened and closed only by a specific lock. As an effect, it is described that even if a key with the same key shape is made, the key cannot be released unless a contact IC tag is built in. Paragraph (0027) describes that the electric lock is unlocked by authentication of only the IC tag.

JP-A-10-252327

The conventional cylinder locks that are easily exchanged have the following problems.
(1) A system that can be used by a single person is acceptable. However, in a system in which a plurality of persons each having different authority use the same storage, as in a normal office of a company, each person can be individually assigned to a different person. It was difficult to have a vault key available. That is, for example, if people A, B, and C have the right to access different storage groups, each person must have a key that can open and close the storage that the person can access. could not.

(2) Further, the system described in Patent Document 1 has the following problems.
In other words, the contact type IC tag is used only for confirmation, and the actual opening and closing of the key is a condition that the shape of the key insertion part matches the lock, so in the office, If you want to examine documents in multiple vaults, you need to move between vaults with a lot of keys. It was inconvenient to move with a lot of keys, and it was very inefficient because we had to find a certain key each time.
Moreover, unlocking the electric lock by recognizing the IC tag means that there is no difference between simply reading the IC tag embedded in the card and unlocking the electric lock, and combining the key and the IC tag. There is no. In other words, since an electric lock is required, there is a problem that the cost increases.
Further, in the technique of Patent Document 1, since the contact IC tag is exposed to the key holding part, the reading device must be arranged outside the lock, and may be damaged by collision or mischief of equipment. There is.

(3) In recent years, security management in offices has become stricter with the enforcement of the Personal Information Protection Law. Until now, keys that have been managed by individuals are often prohibited from being taken out of the office. That is, when leaving the office, there are many cases where it is required to store keys managed by individuals in the key management box.
(4) On the other hand, when one individual key is assigned to an individual, a key management box is required to store as many keys as the number of people using the keys in the office. The time for one person to use the key is usually a short time of the day. For this reason, even keys with little usage time must be stored, and the key management box occupies a useless space.

(5) In some storages, an IC card having an IC tag is used as a key. The vault reads information from the IC tag of the IC card held over the authentication device, and permits opening and closing when authentication is successful based on the information. Also, in office wiring work, etc., an unspecified number of traders enter and leave, so one or more entry authorities are stored in the IC card assigned to each trader, and the IC card is held over the authentication device provided for each room. Only when authorization is successful, entry is allowed. These IC cards are stored in a key box when the office furniture is not used or when the user goes out of the office in order to tighten security management. If this IC card is also prepared for the number of people using the IC card, the key box becomes large, which is not preferable.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a compact digital key box.

In order to achieve the above object, a digital key box according to the present invention has the following configuration.

A data writing means for writing at least one of the door identification data, a lock means for restricting attachment / detachment of the digital key, and a specific user who has been successfully recognized by the personal authentication means is a person who has been given a personal digital key. In some cases, the personal digital key having user identification information of the specific user is allowed to be removed from the lock means, and the specific user who has been successfully authenticated by the personal authentication means is given a personal digital key. If not, the data writing means restricts the attachment / detachment restriction of the common digital key to which the data has been written. Having a lock release means for releasing the click means.

Here, “door” refers to drawers such as storages or desks that store stored items, doors that are opened or closed, doors that are provided at the entrance of the room, and openable bars that are provided in the entrance / exit device. Etc. are included.
In addition, the meaning of “common” is subjective in the sense that multiple people use one common digital key, and objective in the sense that one common digital key can be used in multiple vaults. Can be considered common. In this specification, focusing on the subjective common, digital keys that are individually assigned individually are referred to as “individual digital keys”, and digital keys that are commonly used by a plurality of users are referred to as “common digital keys”. .

(3) In the invention described in (1) or (2), a group creation unit that groups a plurality of the common digital keys into a first group that complies with a first condition and a second group that complies with a second condition .
(4) In the invention described in (3), the group creating means includes at least one of the attribute of the user, the frequency with which the user uses the common digital key, and the time zone in which the common digital key is used. Based on the above, the first and second groups are created.

Storing the door specifying data for specifying two or more doors having the lock permission; when the digital key box recognizes the specific user, the IC tag of any common digital key A data writing means for writing at least one of user identification information of the corresponding user or door identification data of the corresponding user, and a common digital key It has a locking means for limiting the removable, the unlocking means the data writing means to release the locking means releasably limit of the common digital key data is written to the IC tag. Such a digital key box allows a user to create a digital key dedicated to the user on the spot, so that the number of digital keys is half the number of all users or about one third of the number. Can be managed with a digital key box, and the digital key box can be made compact.

  The digital key box of the present invention is for centrally storing and managing digital keys used by a user to unlock a plurality of doors. In the digital key box having means, the digital key includes an IC tag, the IC tag has user identification information for identifying the user, and the user has permission to unlock the door among the plurality of doors 2 The door specifying data for specifying the door described above is stored, the personal digital key assigned to each person, the IC tag, the user identification information for the IC tag to identify the user, A plurality of doors for storing door identification data for identifying two or more doors that the user has permission to unlock, and a common digital key used in common by the plurality of users. Including When the digital key box recognizes a specific user by the personal authentication means, at least the user identification information of the corresponding user or the door identification data of the corresponding user is added to the IC tag of any common digital key. Data writing means for writing one data, locking means for restricting attachment / detachment of the digital key, and a specific user who has been successfully recognized by the personal authentication means is a person who has been given a personal digital key. If the specific user who succeeds in the authentication by the personal authentication means is not the person who has been given the personal digital key, the data writing means will store the data. There is a lock release means for causing the lock means to release the attachment / detachment restriction of the written common digital key. Such a digital key box can unlock the door using a common digital key even if the frequency of use of the electronic key is low. In addition, since a plurality of users share a common digital key, the digital key box can reduce the number of electronic keys to be managed as compared to the case of managing a personal digital key assigned to each user. Therefore, according to the digital key box of the present invention, the digital key box can be made compact.

  In addition, the digital key box of the present invention has group creating means for grouping a plurality of common digital keys into a first group that complies with the first condition and a second group that complies with the second condition, and therefore belongs to the first group.

  Next, an embodiment of a digital key box according to the present invention will be described with reference to the drawings.

<Overall configuration of digital key box>
FIG. 1 shows a configuration diagram of the digital key box 30.
The digital key box 30 is for centrally storing and managing the electronic keys 1 used to unlock the doors of a plurality of storages. The digital key box 30 is provided with an opening / closing door 31, and the opening / closing door 31 is normally closed. Inside the open / close door 31 of the digital key box 30, a key hole unit 38 (from 38A to 38J) for holding ten electronic keys 1 (see FIG. 6) is attached. An IC card reading unit 32, a numeric keypad operation unit 33, and a liquid crystal display unit 34 are attached to the right surface of the open / close door 31 of the digital key box. The key hole unit 38 has a key hole 35 in which the electronic key 1 is mounted, an LED 43, and a name plate 37. The key hole 35 is in a state in which the electronic key 1 cannot normally be removed by the lock means 41 (see FIG. 2) which is a key removal prevention means.

Next, the controller of the digital key box will be described. FIG. 2 is a block diagram showing the control configuration. The controller 44 includes a CPU 45, a ROM 46, and a history storage unit 49. The ROM 46 includes a control program 50, an electronic key ID storage unit 47, an access right storage unit 48, and an effective time data setting unit 51.
When the electronic key 1 is attached to the controller 44, the electronic key 1 is attached to the controller 44 when the electronic key 1 is attached to the controller 44. IC tag data reading means 42A to 42J for reading data stored in the built-in IC tag 13, data writing means 40A to 40J for writing valid time data to the electronic key 1, and for identifying a user Data writing means 39 </ b> A to 39 </ b> J and LEDs 43 </ b> A to 43 </ b> J for writing data such as door identification data for identifying the personal ID number and the door of the storage room that the user has permission to unlock to the electronic key 1 are connected. Further, a liquid crystal display unit 34, a numeric keypad operation unit 33, and an IC card reading unit 32 are connected to the controller 44.

<Structure of electronic key>
FIG. 6 is a diagram showing the electronic key 1.
The electronic key 1 includes an IC tag 13. The IC tag includes a memory that can read and write data and programs, a CPU that processes and calculates data, and the like. The first terminal 11 and the second terminal 12 are connected to the IC tag 13. The IC tag 13 is covered with an insulating cover 4. The second terminal 12 has a shape that can be inserted into the key hole 35 of the digital key box 30 or the lock of the storage, and is provided so as to protrude from the case 4 to the outside. The second terminal 12 includes a recess 2d with which the locking means 41 (FIG. 2) is engaged. The first terminal 11 has a plate shape, is disposed so as to be orthogonal to the second terminal 12, and is exposed to both sides of the second terminal 12 outside the case 4. The electronic key 1 is provided with an LED 9 so as to be visible.

FIG. 7 is a diagram showing a circuit configuration of the electronic key 1.
In the electronic key 1, an IC tag 13 is disposed between the first and second terminals 11 and 12. The LED 9 is provided in parallel with the IC tag 13 and is lit using current flowing through the first and second terminals 11 and 12. Therefore, the electronic key 1 is used when the first and second terminals 11 and 12 are normally in contact with the reader / writer and the IC tag 13 reads data normally or the data is normally written to the IC tag 13. The LED 9 is lit on the first and second terminals 11 and 12. Therefore, the user can confirm whether or not data has been normally read from and written to the IC tag 13 based on whether or not the LED 9 is lit.

<Usage of digital key box>
Next, a usage form of the digital key box 30 of the embodiment will be described.
There are two possible ways of using the digital key box 30 having the above configuration. Those methods are changed by the control program 50 stored in the ROM 46. Two methods, the personal digital key method and the common digital key method, will be described in sequence.
<Personal digital key method>
In this method, one electronic key 1 is assigned to each individual. The digital key box 30 shown in FIG. 1 can manage the electronic keys 1 for 10 people. The electronic key 1 stores a unique identification number (electronic key ID). In this embodiment, the unique identification number of the contact IC tag 13 is used as the electronic key ID. Commercially available contact IC tags each have a unique identification number, are not identical, and are difficult to rewrite. The electronic key ID is used as user identification information for identifying the user.

FIG. 3 is a flowchart showing the control program 50 in the case of the personal digital key method.
The user goes to the digital key box 30 and causes the IC card reading unit 32 to read the IC card he has (S11; YES). Then, the personal identification number is input by the numeric keypad 33 (S12). The electronic key ID storage unit 47 of the controller 44 stores a personal identification number corresponding to the IC card read by the IC card reading unit 32, and collates the input personal identification number (S13). Only when the correct password is input (S13; YES), after the effective time data set by the effective time data setting unit 51 is written to the electronic key 1 by the effective time data writing means 40, the door 31 is opened. Open. In the present embodiment, the numeric keypad 33 is used, but personal authentication may be performed by a vein authentication device, a fingerprint authentication device, or the like. The personal authentication is performed in order to prevent an illegal act from being performed using another person's IC card.

Here, the valid time data setting unit 51 sets valid time data based on at least one of the attribute of the user, the type of the stored item, and the installation location of the storage.
For example, the effective time data setting unit 51 stores the user in a normal employee class, a section manager class, a manager class, and an officer class. For example, the effective time of the normal employee class is 5 minutes, and the effective time of the section manager class is set. The length of the effective time is set according to the hierarchy, such as 10 minutes, the effective time of the general manager class is set to 15 minutes, and the effective time of the officer class is set to 20 minutes.
Further, for example, the effective time data setting unit 51 sets the effective time for the storage storing the document file to the storage storing the CD-ROM or USB memory in consideration of the time for opening the storage and checking the document contents. Set longer than the valid time.
Further, for example, the effective time data setting unit 51 stores the effective time for the storage on the 10th floor above the ground on the 2nd floor when the digital key box 30 is located on the 2nd floor in a 2 floor underground building, for example. Set longer than the valid time for the warehouse.

The controller 44 opens the open / close door 31 and simultaneously releases the lock means 41 of the key hole unit 38 to which the personal electronic key 1 for which personal authentication has been performed is mounted (S14). The lock means 41 uses the recess 2d of the electronic key 1 to drive and engage / release a lock member (not shown) with a solenoid. Further, the LED 43 of the released keyhole unit 38 is turned on (S14). Thus, the user can remove the electronic key 1 dedicated to the user. When the IC tag data reading means 42 no longer detects the electronic key 1, the controller 44 determines that the electronic key 1 has been removed from the key hole 35 (S15; YES), and the authenticated individual and the extracted electronic After the key 1 and the extracted time are stored in the history storage unit 49 (S16), the process proceeds to S19.
In this digital key box 30, since the electronic key 1 is directly attached to the key hole 35, the IC tag data reading means 42 attached to the key hole unit 38 is used to read the IC tag data of the attached electronic key 1. Therefore, it is possible to reliably manage whether or not the electronic key 1 is a regular key.

  In the case of the personal digital key method, door specifying data possessed by a specific individual corresponding to the electronic key 1 is stored in the electronic key 1 in advance. Here, when the number of storages accessible to a specific individual increases or decreases, the door specifying data of the electronic key 1 is rewritten while the digital key box 30 stores the electronic key 1. In order to ensure security, the electronic key 1 is basically returned to the digital key box 30 except during use. Therefore, the electronic key 1 stores the latest door identification data in response to a change in the storage that can be unlocked by the user, and can avoid the inability to use a storage that can be unlocked by a specific individual.

  Since the conventional electronic key stores only one repository that can be used by an individual and is used as a dedicated key for the archive, the archive stores the electronic key ID of the user who can unlock the lock in the memory. When the electronic key ID read from the electronic key is registered in the memory, it is unlocked. When the user who can unlock the storage changes, the storage has rewritten the electronic key ID registered in the memory. This rewriting takes time and labor if input manually for each storage, and there is a risk of input leakage. On the other hand, if the storage is connected to the server via the network, it is possible to reduce the trouble of input and the risk of input leakage, but the system becomes expensive. On the other hand, if the storage uses a system that unlocks the electronic key 1 that stores the door identification data in the IC tag 13 and confirms that it has an identification number that it manages, it can be unlocked. Thus, it is not necessary to store the electronic key ID or to construct a network, and it is possible to construct a system that can appropriately cope with a change in the unlocking authority at low cost.

  In addition, when the electronic key 1 is taken out, the digital key box 30 stores, for example, effective time data indicating that the storage A can be unlocked for five minutes after the electronic key 1 is taken out from the digital key box 30. The data is stored in the IC tag 13. The user goes from the installation location of the digital key box 30 to the storage A in which a desired storage item (document file, CD-ROM, USB, personal computer, etc.) is stored, and the key provided with the electronic key 1 in the storage. Insert into the lock of the unit.

  IC tag data reading means for reading data from the IC tag 13 by contacting the first and second terminals 11 and 12 provided on the IC tag 13 of the electronic key 1 is provided on the lock of the storage A. The key unit reads the valid time data corresponding to the storage A from the IC tag 13 of the electronic key 1 by the IC tag data reading means. The key unit permits the storage A to be opened and closed when the electronic key 1 is inserted into the lock of the storage A within the effective time indicated by the effective time data. On the other hand, the key unit does not permit opening / closing of the storage A if the electronic key 1 is not inserted into the lock of the storage A within the effective time indicated by the effective time data. Thus, the electronic key 1 loses its function as the key of the storage A when the valid time has elapsed.

  For this reason, even if the valid time has passed without the electronic key 1 being returned to the digital key box 30 after the user opens and closes the storage A, the electronic key 1 is used even by a user having a legitimate authority. Therefore, the storage A cannot be opened and closed. In this case, if the user goes to the digital key box 30 and returns the electronic key 1 once, and takes the procedure for taking out the electronic key 1 again and writes the valid time data to the electronic key 1, the user uses the electronic key 1. You can open and close the vault.

When the storage is unlocked, the storage identification number, the date and time of unlocking, and the date and time of unlocking are written in the IC tag 13 of the electronic key 1 by the controller on the storage side. In addition, the storage places an imaging means such as a CCD camera near the lock into which the electronic key 1 is inserted, and images the face of the person who unlocked the storage with the imaging means. The controller on the storage side writes the image data picked up by the image pickup means into the IC tag 13 of the electronic key 1 as one of the usage histories. When a plurality of storage boxes are unlocked with the electronic key 1, all usage history data is stored in the IC tag 13 of the electronic key 1.
When the electronic key 1 is returned to the digital key box 30 (when the sampling cannot be confirmed) (S15: NO), the IC tag data reading means 42 reads the electronic key ID of the electronic key 1 and specifies the personal authentication. It is confirmed that the correct electronic key 1 corresponding to the individual is returned (S17; YES), and the return time is stored in the history storage unit 49 (S18). Next, the usage history read from the IC tag 13 of the electronic key 1 by the IC tag data reading means 42 of the controller 44 is stored in the history storage unit 49 as the usage history of the personal electronic key 1 (S19).

As a result, the history storage unit 49 stores all the date and time when each electronic key 1 was taken out from the digital key box 30, the date and time when it was returned, and the usage history at the storage.
Later, when troubles such as loss of documents in the vault occur, by checking the usage history stored in the IC tag 13 of the electronic key 1 or the history storage unit 49 of the controller 44, the responsibility Can be pursued. Further, by notifying the user that all histories are managed, it is expected that the user can quickly use the storage after taking out the electronic key 1 from the digital key box 30. It is possible to avoid a situation in which 1 is left on the desk for a long time.
Thereafter, the liquid crystal display unit 34 is instructed to close the open / close door 31 (S20). After confirming that the door 31 is closed (S21; YES), the process returns to S11.

  According to the digital key box 30 of the personal digital key system, the electronic key 1 used by the user is centrally stored and managed in order to unlock a plurality of storages disposed in the office. In the digital key box 30 to which the electronic key 1 is attached and has a ten key operation unit 33 and an electronic key ID storage unit 47 as personal authentication means, (a) the electronic key 1 includes an IC tag, and the IC tag 13 And (b) the digital key box 30 is stored in the electronic key ID and the door specifying data for specifying two or more storages that the user has permission to unlock from among the plurality of storages. The data reading means 42A, 42B... For reading data from the IC tag 13 of the key 1 and the lock means 41A, 41B. When the user is recognized (S13; YES), the lock means 41 has the lock release means (S14) for releasing the restriction on the attachment / detachment of the electronic key 1 having the personal identification information of the corresponding user. This is convenient because it is only necessary to have one electronic key 1 when sequentially checking the storage boxes permitted to be unlocked. Further, since the electronic key 1 managed by an individual can also be managed by the digital key box 30, it is possible to prohibit an individual from taking out the electronic key 1 from the office.

  In the digital key box 30 of this embodiment, the IC tag 13 stores the usage history using the storage, and the IC tag data reading means 42 reads the usage history (S19). When the user returns the electronic key 1 to the digital key box 30, the digital key box 30 can grasp the usage history of the electronic key 1, so the user takes out the electronic key 1 at what time and which storage box It is possible to grasp the usage history of how long it has been used, and to sufficiently manage the electronic key 1.

  The digital key box 30 according to the present embodiment includes valid time data writing means 40 that writes valid time data indicating valid time during which the storage can be unlocked using the door specifying data to the IC tag 13 of the electronic key 1. For this reason, when the electronic key 1 taken out from the digital key box 30 has passed the effective time specified by the effective time data, the storage can not be unlocked even if it is inserted into the lock of the storage, and the function as a key is lost. Therefore, according to the digital key box 30 of the present embodiment, the risk of unauthorized use of the electronic key 1 can be reduced.

  In the digital key box 30 of the present embodiment, the valid time data writing means 40 changes the valid time according to at least one of the user attribute, the type of stored item, and the installation location of the storage, and the IC tag 13 Is what you write. Since such a digital key box 30 stores an effective time suitable for the user, stored items, and storage location in the IC tag 13, a third party can digitally compare the effective time with a uniform setting. Opportunities for unauthorized use of keys are reduced, and security can be improved. In addition, even if the electronic key 1 loses its function as a key after the effective time has elapsed, if the electronic key 1 is stolen by a third party, the responsibility is pursued from the usage history remaining in the digital key box 30. Therefore, the user can also improve security in that the user is conscious of returning the electronic key 1 quickly.

<Common digital key method>
The common meaning is subjective common in the sense that a plurality of people use one electronic key 1 and objective common in the sense that one electronic key 1 can be used in a plurality of storages. Conceivable. In this specification, focusing on the subjective common, the electronic key 1 assigned individually one by one is referred to as “personal digital key”, and the electronic key 1 commonly used by a plurality of users is referred to as “common digital key”. " Therefore, the common digital key method is a method of managing the electronic key 1 as a common digital key without assigning each electronic key 1 to an individual. Since the basic configuration is the same as that of the personal digital key system, only the differences will be described in detail.
In the digital key box 30 shown in FIG. 1, ten electronic keys 1 can be managed.

FIG. 4 is a flowchart showing the control program 50 in the case of the common digital key method.
The user goes to the digital key box 30 and causes the IC card reading unit 32 to read the IC card possessed (S30; YES). Then, a password is input by the numeric keypad operation unit 33 (S31). The electronic key ID storage unit 47 of the controller 44 stores a personal identification number corresponding to the IC card read by the IC card reading unit 32, and collates the input personal identification number (S32). Only when the correct password is input (S32; YES), the door 31 is opened. In the present embodiment, the numeric keypad 33 is used, but personal authentication may be performed by a vein authentication device, a fingerprint authentication device, or the like. The personal authentication is performed in order to prevent an illegal act from being performed using another person's IC card.

After S33, the control is divided into two routes. If the controller 44 determines that the user is not currently borrowing the electronic key 1 (S33; NO), the process proceeds to S34. On the other hand, if the controller 44 determines that the user is currently borrowing the electronic key 1 (S33; YES), the process proceeds to S42.
First, the case where the user is not currently borrowing the electronic key 1 (S33; NO) will be described.
In this case, the storage unit number required by the user is input to the liquid crystal display unit 34 (S34). In this case, taking advantage of the characteristics of the liquid crystal display unit 34, it is preferable to perform a display or the like so that the user can easily specify the storage number.
When the user inputs the storage number (S34), whether or not the number input is completed is displayed on the liquid crystal display unit 34 and checked (S35). When the user wants to unlock a plurality of storages, he / she inputs the numbers of all storages (S34, S35).

The controller 44 collates the input storage number with the access right storage unit 48 that stores for each user the access right to unlock the storage and access the stored items, and the user who has succeeded in personal authentication. Is accessible to all the storages of the number entered by the data writing means 39, the number of the storage unit entered by the data writing means 39 is used as the door identification data, and any of the electronic keys 1 currently stored in the digital key box 30 is stored. Write to the IC tag 13 (S36). At the same time, the valid time data set by the valid time data setting unit 51 and the personal ID number (an example of user identification information) for identifying the user are written in the IC tag 13 (S36). Thereby, the common electronic key 1 becomes a key only for the user. If the storage number for which the user does not have access rights has been entered, a message to that effect is displayed on the liquid crystal display unit 34.
Next, the controller 44 opens the open / close door 31 and simultaneously releases the lock means 41 of the key hole unit 38 to which the arbitrary electronic key 1 in which data is written is mounted (S37). The lock means 41 uses the recess 2d of the electronic key 1 to drive and engage / release a lock member (not shown) with a solenoid. Further, the LED 43 of the released keyhole unit 38 is turned on (S37). The user can easily remove the electronic key 1 that has become a dedicated key by turning on the LED 38. When the IC tag data reading means 42 no longer detects the electronic key 1, the controller 44 determines that the electronic key 1 has been extracted from the key hole 35 (S 38; YES), and the authenticated individual and the extracted electronic The key 1 and the extracted time are stored in the history storage unit 49 (S39). Thereafter, the liquid crystal display unit 34 is instructed to close the open / close door 31 (S40). After confirming that the door 31 is closed (S41; YES), the process returns to S30.

In this digital key box 30, since the electronic key 1 is directly attached to the key hole 35, the IC tag data reading means 42 attached to the key hole unit 38 is used to read the IC tag data of the attached electronic key 1. By reading, it is possible to reliably manage whether or not the electronic key 1 is a legitimate key.
When the storage is unlocked, the storage tag identification number, the date and time of unlocking, and the date and time of unlocking are written in the IC tag 13 by the controller on the storage side. When a plurality of storage boxes are unlocked with the electronic key 1, all usage history data is stored in the IC tag 13 of the electronic key 1.

Next, a case where the user currently borrows the electronic key 1 (S33; YES) will be described. In this case, the controller 44 opens the open / close door 31 and simultaneously releases the lock means 41 of the key hole unit 38 to which the electronic key 1 is not attached (S42).
The user returns the electronic key 1 to any key hole 35 in which the electronic key 1 is not mounted (S43). When the electronic key 1 is returned to the digital key box 30, the IC tag data reading means 42 reads the electronic key ID of the electronic key 1, and the electronic key 1 borrowed by a specific individual who has been personally authenticated is returned. This is confirmed (S44; YES), and the return time is stored in the history storage unit 49 (S45). Next, the use history data read from the electronic key 1 by the IC tag data reading means 42 of the controller 44 is stored in the history storage unit 49 as the use history of the personal electronic key 1 (S46).

Thereby, the history storage unit 49 stores all the date and time taken out from the digital key box 30, the date and time returned, and the usage history in the storage for each electronic key 1.
Later, when troubles such as loss of documents in the vault occur, the location of responsibility can be pursued by checking the usage history. Further, by notifying the user that all histories are managed, it is expected that the user can quickly use the storage after taking out the electronic key 1 from the digital key box 30. It is possible to avoid a situation in which 1 is left on the desk for a long time.
Thereafter, the liquid crystal display unit 34 is instructed to close the open / close door 31 (S40). After confirming that the door 31 is closed (S41; YES), the process returns to S30.

  According to the digital key box 30 of the common digital key system, the electronic key 1 that is a common digital key that is commonly used by a plurality of users is concentrated in order to unlock a plurality of storages disposed in the office. In the digital key box 30 to which the electronic key 1 is attached and which has the numeric key operation unit 33 and the electronic key ID storage unit 47 as personal authentication means, (a) the electronic key 1 An ID tag of an individual that includes the IC tag 13 and identifies the user, and door identification data that specifies two or more storages that the user has permission to unlock from among a plurality of storages (B) When the digital key box 30 recognizes the specific user by the personal authentication means 30, the IC tag 13 of any electronic key 1 has the ID number of the specific user, Data writing means (S36) for writing at least one of the door specifying data for specifying the storage for which the user has permission to unlock, lock means 41A, 41B for restricting attachment / detachment of the electronic key 1, and data The writing unit has a lock release unit (S37) that causes the lock unit 41 to release the restriction on the attachment / detachment of the electronic key 1 in which the data is written to the IC tag 13. Since such a digital key box 30 can create a user-specific key for the user on the spot, the number of keys is about half the number of all users or about one-third of the number of users. It only needs to be managed with a digital key box, and the digital key box can be made compact.

  Even if the digital key box 30 adopts the common digital system, the usage history of the storage is read from the electronic key 1 and stored, or the effective time data is written in the electronic key 1 to be the same as the personal digital system. Has the effect of.

  By the way, when all the electronic keys 1 are lent out, the digital key box 30 writes the user's storage data and ID number into the electronic key 1 that is shared by a plurality of people, and is a key dedicated to the user. Can no longer be issued. In this case, the user is inconvenient because the user cannot unlock the storage and take out stored items such as document files, CD-ROMs, and USB memories. That said, if all electronic keys 1 are for personal use, the number of electronic keys 1 to be managed increases and the cost increases, and it is useless to give one electronic key 1 to those who use it less frequently. It is. Therefore, the digital key box 30 groups the electronic keys 1 managed by the keyhole units 38A to 38J, and changes the conditions for using the electronic key 1 for each group.

FIG. 5 is a flowchart showing a program for grouping commonly used electronic keys 1 (common digital keys). This program is stored in the ROM 46 of the controller 44.
For example, the controller 44 is common when a user inputs a common digital key grouping command to the controller 44 or when a certain period (for example, one year) has passed since the most recent grouping of common digital keys. When a digital key grouping command is input, conditions for grouping common digital keys are set (S51: YES, S52). The condition setting may be input by the administrator of the controller 44 every time a common digital key grouping command is input, or may be used by updating the conditions used in the most recent common digital key grouping. .

  Then, it is determined whether the set condition relates to the user attribute. In the case of the user attribute, the user attribute (for example, the normal employee class, the section manager class, and the department manager class) that can use the electronic key 1 as the common digital key is read from the memory of the controller 44 and acquired ( S53: YES, S54). Then, the number of people is counted for each attribute, and the number of common digital keys distributed to each group is determined. For example, when the number of users who can use the electronic key 1 as a common digital key is 30, it is assumed that the regular employee class is 20, the section manager class is 7, and the department manager class is 3. Since the department manager class is considered to use the electronic key 1 frequently, three electronic keys 1 corresponding to the number of persons belonging to the department manager class are assigned to the department manager class group. Although the section manager class uses the electronic key 1 less frequently than the department manager class, it is considered that the section manager class uses the electronic key 1 more frequently than the regular employee. Therefore, the electronic key 1 is assigned to the section manager class group at a rate higher than the rate at which the employees of the regular employee class share the electronic key 1. For example, three electronic keys 1 are assigned to the section manager class group, and four electronic keys 1 are assigned to the normal employee class group (S55).

  Then, the key hole box 38 for managing the electronic key 1 assigned to each group is determined, and the common digital keys are grouped. For example, the electronic key 1 of the general manager class is managed by the keyhole boxes 38A to 38C. Further, the electronic key 1 of the manager class group is managed by the key hole units 38D to 38F. Further, the electronic key 1 of the group of the flat employee class is managed by 38G to 38J (S56). Thereafter, the process ends.

  Thereby, the general manager class user can take out the electronic key 1 whenever he / she comes to the digital key box 30 and can use the electronic key 1 in the same manner as the personal electronic key 1. In addition, the section manager class user can easily take out the electronic key from the digital key box 30 by a regular employee, although the electronic key 1 cannot be assigned one by one. Therefore, by grouping common digital keys according to user attributes, all the electronic keys 1 in the digital key box 30 can be lent out to regular employees, reducing the problem that users of department managers and section managers cannot use the electronic keys 1 it can.

  When the setting condition relates to the usage frequency of the common digital key, the usage history of the user is read from the history storage unit 49, and the users are grouped according to the usage frequency. Then, to the group of users who are frequently used, the electronic keys 1 are assigned to the users who are frequently used so that the users belonging to the group can use the electronic keys 1 at any time. Further, the remaining electronic key 1 is assigned to a group that is less frequently used. For example, six electronic keys 1 are assigned to a group of users who are frequently used, and the remaining four electronic keys 1 are assigned to a group of users who are less frequently used (S57: YES, S58, S59). ). Then, similarly to the case of the user attribute, the electronic keys 1 are grouped and the process is terminated (S56).

  By grouping the common electronic keys 1 in accordance with the usage frequency in this way, it is possible to reduce a problem that a user with a high usage frequency cannot use the electronic key 1.

  When the setting condition relates to the usage time zone of the common digital key, the usage history of the user is read from the history storage unit 49, and the usage time is grouped by counting the users for each usage time zone. Then, the number of electronic keys 1 to be assigned is increased for a group of usage time zones with many users, and the number of electronic keys 1 to be assigned is reduced for a group of usage time zones with few users. For example, seven electronic keys 1 are assigned to a group of usage hours from 9:00 to 12:00, and three electronic keys 1 are assigned to a group of usage hours from 11:00 to 14:00. Furthermore, since the group of the time zone from 13:00 to 16:00 does not overlap with the time zone from 9:00 to 12:00, seven electronic keys 1 are assigned (S60: YES, S61, S62). Then, similarly to the case of the user attribute, the electronic keys 1 are grouped and the process is terminated (S56).

  Thus, by grouping the common electronic keys 1 according to the use time zone, the electronic keys 1 can be left in the digital key box 30 by the number determined according to the time zone.

  In this way, the digital key box 30 in which the common electronic keys 1 are grouped can be used by the user in which group of the electronic keys 1 based on information read by the IC card reading unit 32 from the user's IC card. Judge whether you are a person. For example, if the user is a section manager, it is determined that the electronic key 1 of the keyhole units 38D to 38F can be used. In this case, the digital key box 30 writes the user's ID code and door identification data in the electronic key 1 of the keyhole unit 38D, for example, releases the lock means 41D, and turns on the LED 43D. Therefore, the user can unlock the storage by taking out the electronic key 1 which is a key for himself / herself from the key hole unit 38.

  When the user returns the electronic key 1, the digital key box 30 determines which group of electronic keys 1 the user has based on the information read from the IC card by the IC card reader 32. Determine if you can use it. Then, among the keyhole units 38 of the group to which the user belongs, the lock means 41 of the keyhole unit 38 in which the electronic key 1 is not inserted into the lock 35 is unlocked, and the LED 43 is turned on. For example, if the user of the previous section manager returns the electronic key 1 and the electronic key 1 is not inserted into the key hole unit 38D, the controller 44 unlocks the lock means 41D and turns on the LED 43D. Lights up. The user inserts and returns the electronic key 1 to the lock 35D where the LED 43D is lit. Note that the return location of the electronic key 1 may not coincide with the rental location as long as it is the key hole unit 38 in the same group. Therefore, the electronic keys 1 of each group are returned to any of the key hole units 38 that manage the electronic keys 1 of each group, and the number of electronic keys 1 assigned to each group does not deviate.

  Therefore, the digital key box 30 according to the first embodiment includes group creating means (S53 to S62) for grouping the plurality of electronic keys 1 into a first group that complies with the first condition and a second group that complies with the second condition. Therefore, the electronic key 1 belonging to the first group and the electronic key 1 belonging to the second group have different conditions (for example, the user attribute, the frequency with which the user uses the common digital key, and the common digital key is used. Can be used by the user in the time zone). As a result, it is possible to solve a problem peculiar to the common digital key system that the electronic key 1 does not remain in the digital key box 30 during a time period when the electronic key 1 is used frequently or when the electronic key 1 is used frequently.

<Combination method>
The combined method is a method in which a single digital key box 30 manages a plurality of electronic keys 1 using a personal digital key method and a common digital key method together. Since the basic configuration of the personal digital key and the common digital key is the same as the personal digital key and the common digital key, only the differences will be described in detail.
In the combined method, for example, in the digital key box 30 shown in FIG. 1, the electronic key 1 serving as a personal digital key is accommodated in the key hole units 38A to 38G, and the electronic key 1 serving as a common digital key is accommodated in the key hole units 38H to 38J. Accommodate.

  The key hole units 38A to 38G for accommodating the electronic key 1 serving as a personal digital key are provided with a data reading means 42 for reading data of the IC tag 13 and a specific user when the IC card reading unit 32 recognizes a specific user. There is a first lock release means for releasing the lock means 41 of the personal digital key having the user door specifying data.

  On the other hand, the key hole units 38H to 38J that accommodate the electronic key 1 serving as a common digital key can be used for any common digital key IC tag when the IC card reader 32, which is a personal authentication means, recognizes a specific user. 13 is a data writing means 39 for writing at least one of a specific user ID number or user door specific data, lock means 41A, 41B... For locking the electronic key 1, and any common digital key. The second lock release means for releasing the lock means 41A, 41B.

  Such a digital key box 30 is stored in the key hole units 38H to 38J without giving the electronic key 1 as a personal digital key to a person who is less frequently opening and closing the storage (normal employee), for example. The electronic key 1 is used. This is because a person who frequently opens and closes the storage cabinet uses the electronic key 1 less frequently. On the other hand, the digital key box 30 is managed by the digital key box 30 by giving the electronic key 1 as a personal digital key to, for example, a person (manager) who frequently opens and closes the storage.

  When the ID number read by the IC card reader 32 is the ID number of the person who has been given one electronic key 1 to the individual, the digital key box 30 is provided with a control program 50 corresponding to the individual digital key method. Run. Thus, the digital key box 30 unlocks the lock means 41 for the key hole unit 38 that accommodates the user's electronic key 1 corresponding to the ID number. At this time, the digital key box 30 writes the valid time data to the electronic key 1 whose lock is released by the valid time data writing means 40.

  On the other hand, when the ID number read by the IC card reading unit 32 is not the ID number of the person who has been given one electronic key 1 to the individual, the digital key box 30 executes a control program corresponding to the common digital key method. Run. As a result, the digital key box 30 is provided with the door identification data, valid time data, and personal ID of the vault where the user has the authority to unlock the electronic key 1 accommodated in any of the keyhole units 38H to 38J. The number is written, and the electronic key 1 is used as a dedicated key for the user. Then, the digital key box 30 unlocks the lock means 41 of the key hole unit 38 that accommodates the electronic key 1 in which data is written, so that the electronic key 1 that is a dedicated key can be taken out.

  In such a combination method, those who frequently open and close the storage store their personal digital keys in the digital key box 30, so if they go to the digital key box 30, they can take out their electronic keys 1. Unlock storage and use stored items. On the other hand, a person who frequently opens and closes the storage can use the common electronic key 1 to unlock the storage and use the stored items.

  Therefore, according to the digital key box 30 of the present embodiment, for those with a low usage frequency of the electronic key 1, an ID number and door identification data are written in the common electronic key 1 to create a dedicated key and lend it. be able to. In addition, since a plurality of users share the common electronic key 1, the digital key box 30 reduces the number of electronic keys 1 to be managed as compared with the case of managing personal digital keys assigned to each user. be able to.

<Selection method>
The selection method is a method in which the user selects a personal digital key method, a common digital key method, and a combined method for one digital key box 30. Since the basic configuration of the personal digital key and the common digital key is the same as the personal digital key and the common digital key, only the differences will be described in detail.
In the selection method, for example, the personal ID is read by the IC card reading unit 32 of the digital key box 30 shown in FIG. The key method, common digital key method, and combination method can be selected. When the method selection is completed, the digital key box 30 manages the electronic key 1 stored in the key hole unit 38 according to the selected method. Such a digital key box 30 is easy to use because the management method of the electronic key 1 can be arbitrarily selected.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 8 is an external perspective view of the digital key box 60.
The digital key box 60 of the second embodiment is capable of storing a plurality of IC cards 61 (an example of digital keys) equipped with a non-contact type IC tag 62. Is different. Therefore, here, it demonstrates focusing on the point which is different from 1st Embodiment, attaches | subjects the same code | symbol to a common point, and abbreviate | omits description suitably.

  The digital key box 60 shown in FIG. 8 is an integrated authentication box 70 and card storage box 80. The authentication box 70 is provided with a fingerprint reading unit 71 under the liquid crystal display unit 34. The authentication box 70 incorporates a control device 72 (an example of personal authentication means, data writing means, lock releasing means, group creation means, and valid time data writing means) for controlling the operation of the digital key box 60. .

  On the other hand, in the card storage box 80, an opening / closing door 82 is rotatably held in a box-shaped casing 81. An electronic lock (an example of an opening / closing permission unit) (not shown) is attached to the casing 81. An electronic lock (not shown) is engaged with the engaging portion 83 of the opening / closing door 82 to restrict the opening / closing of the opening / closing door 82. Two card storage units 85A and 85B are fixedly attached to the hollow portion 84 of the housing 81. Each of the card storage units 85A and 85B includes storage devices 90A to 90E and 90F to 90J.

FIG. 9 is an external perspective view of the card storage unit 85A as viewed from the front side. FIG. 10 is an external perspective view of the card storage unit 85A as viewed from the back side. FIG. 11 is a cross-sectional view taken along the line AA of FIG. 12 is a cross-sectional view taken along the line BB in FIG. Since the card storage unit 85B has the same configuration as the card storage unit 85A, the description thereof is omitted.
In the card storage unit 85A, storage devices 90A to 90E are held by a cover plate 86. The card storage unit 85A is attached to the casing 81 so that it cannot be removed by locking the locking claws 86a of the cover plate 86 to the casing 81 (see FIG. 8).

  As shown in FIG. 9, openings 87 </ b> A to 87 </ b> E are formed in the cover plate 86 so that the storage devices 90 </ b> A to 90 </ b> E are positioned to expose the insertion port 95. As shown in FIGS. 9 and 10, the storage device 90 includes a case 91 in which first and second case members 92 and 93 made of resin are stacked, and a read / dryer section 98 is stacked and fixed with a fixing screw 106. Thus, the appearance is configured.

  As shown in FIG. 12, the case 91 has a storage portion 99 formed between the first and second case members 92 and 93. The first and second case members 92 and 93 have front panel portions 92a and 93a that are folded at one ends. An insertion port 95 for inserting the IC card 61 into the storage unit 99 is formed between the front panel portions 92a and 93a.

  As shown in FIGS. 9 and 11, the first and second case members 92 and 93 are formed with recesses 92b and 93b in the center of the surface panel portions 92a and 93a, and the IC card 61 stored in the storage portion 99 is taken out. It is easy. As shown in FIG. 9, an LED 94 is provided on the upper side of the insertion port 95 to inform the user of the removal position or return position of the IC card 61.

  As shown in FIG. 12, the case 91 has a shielding member 102 movably disposed on the back side of the insertion port 95. A solenoid 100 is fixed to the first case member 92 with the plunger 101 facing downward. A shielding member 102 is connected to the plunger 101 via a connecting pin 103. Therefore, when the solenoid 100 is not driven, the plunger 101 protrudes from the solenoid 100 and the shielding member 102 is disposed at a shielding position where the insertion port 95 is shielded. On the other hand, when the solenoid 100 is driven, the plunger 101 is attracted by the solenoid 100, and the shielding member 102 is disposed at an open position where the insertion port 95 is opened. In the second embodiment, the locking means 105 that restricts the attachment / detachment of the IC card 61 includes a solenoid 100, a plunger 101, a shielding member 102, and a connecting pin 103.

  As shown in FIGS. 10 and 11, the storage devices 90 </ b> A to 90 </ b> E are attached to the cover plate 86 by bonding the surface panels 92 a and 93 a together. On the cover plate 86, metal support members 89 are respectively fixed below the storage devices 90A to 90E, and support the storage devices 90A to 90E via insulating members 88. Therefore, the storage devices 90A to 90E do not tilt due to their own weight.

  The solenoid 100 and the LED 94 of the reader / writer unit 98 and the locking means 105 are connected to the control device 72 of the authentication box 70 shown in FIG. In the control device 72, a fingerprint of a user who has the authority to open and close the digital key box 60 is registered in advance. The control device 72 stores the user ID for identifying the user, the authority to open and close the digital key box 60, and the use history of the IC card and storage in association with the registered fingerprint. Further, the control device 72 stores a flowchart for using the IC card 61 as a personal digital key or a common digital key.

<Description of operation>
The digital key box 60 operates in the same manner as the digital key box 30 of the first embodiment except that the IC card 61 on which the non-contact type IC tag 62 is mounted is stored. Hereinafter, the operation of the digital key box 60 will be briefly described.
In the digital key box 60, since the control device 72 does not energize the solenoid 100 of the storage devices 90A to 90J during standby, the lock means 105 places the shielding member 102 at the shielding position so that the IC card 61 cannot be taken out. Yes.

  When the user causes the fingerprint reading unit 71 to rub his / her finger to read the fingerprint, the control device 72 of the digital key box 60 confirms the presence or absence of the IC card 61. If there is no IC card 61 in the digital key box 60, a message to that effect is displayed on the liquid crystal display unit 34. On the other hand, when the IC card 61 is in the digital key box 60, the fingerprint read by the fingerprint reading unit 71 is collated with the fingerprint registered in the control device 72. When the fingerprint read by the fingerprint reading unit 71 does not match the registered fingerprint, the control device 72 does not drive the electronic lock (not shown) and does not open / close the card storage box 80.

  On the other hand, when the fingerprint read by the fingerprint reading unit 71 matches the registered fingerprint, it is determined whether the personal IC card 61 of the user is stored in the storage devices 90A to 90J. When the personal IC card 61 is stored in the storage device 90J, for example, the solenoid 100 of the storage device 90J is energized to move the shielding member 102 from the shield position to the open position, and the LED 94 of the storage device 90J is turned on. Light up. When the user removes the IC card 61 from the storage device 90J, the control device 72 stores the read fingerprint and the date and time when the IC card 61 was taken out.

  On the other hand, when the personal IC card 61 is not stored in the storage devices 90A to 90J, one IC card 61 is selected and the read fingerprint is written in the non-contact IC tag 62. Here, it is assumed that a fingerprint is written on the IC card 61 stored in the storage device 90A. Then, the control device 72 energizes the solenoid 100 of the storage device 90 </ b> A to open the insertion port 95 in the shielding member 102. Further, the control device 72 turns on the LED 94 of the storage device 90A to inform the user of the position of the IC card 61 that can be extracted. When the user removes the IC card 61 from the insertion port 95, the control device 72 stores the usage history of the IC card 61 in the same manner as the personal IC card 61. When the control device 72 detects that the open / close door 82 is closed, the control device 72 stops energization of the solenoid 100 and causes the shielding member 102 to shield the insertion port 95.

  When taking out or returning the stored item from the storage using the IC card 61, the user holds the IC card 61 over the authentication device of the storage. Then, the vault reads the fingerprint stored in the IC card 61 and collates it with the fingerprint registered in the control device on the vault side, and when the fingerprint read from the IC card 61 matches the registered fingerprint. As long as it opens and closes the vault.

  When returning the IC card 61 to the digital key box 60, the user opens the opening / closing door 82 by causing the fingerprint reading unit 71 to read the fingerprint. For example, the control device 72 blinks the LED 94 of the storage device 90C in which the IC card 61 is not stored, and notifies the user of the return position. Further, the control device 72 energizes the solenoid 100 of the storage device 90 </ b> C to open the insertion port 95 in the shielding member 102. When the user stores the IC card 61 in the storage unit 99 of the storage device 90C and closes the open / close door 82, the control device 72 reads the fingerprint from the non-contact type IC tag 62 of the IC card 61, and the fingerprint reading unit 71 Judge whether it matches the read fingerprint.

If the fingerprint read from the non-contact IC tag 62 of the IC card 61 matches the fingerprint read by the fingerprint reading unit 71, the control device 72 returns the fingerprint read by the fingerprint reading unit 71 and the IC card 61. Memorize the date and time.
On the other hand, if the fingerprint read from the non-contact IC tag 62 of the IC card 61 does not match the fingerprint read by the fingerprint reading unit 71, an alarm is issued and an abnormality is notified to the administrator.

<Effect>
Therefore, since the digital key box 60 of the second embodiment is obtained by changing the storage object from the electronic key 1 to the IC card 61 in the digital key box 30 of the first embodiment, the digital key box 60 of the first embodiment is the same as the digital key box 30 of the first embodiment. The same effect is obtained.

  Briefly, the digital key box 60 creates a specific user's IC card 61 by writing a specific user's fingerprint (user identification information) on an IC card 61 commonly used by a plurality of people. To do. Then, the solenoid 100 of the IC card 61 in which the fingerprint is written is energized to place the shielding member 102 in the open position so that the IC card 61 can be taken out. Therefore, the digital key box 60 does not need to manage the IC cards 61 by the number of users, and the digital key box 60 can be made compact.

  The digital key box 60 is a personal IC card 61 (personal digital key) in which a fingerprint of a specific user is previously written on the IC card 61 in addition to an IC card 61 (common digital key) commonly used by a plurality of people. When the user specified by fingerprint authentication is a person who has the personal IC card 61, the solenoid 100 of the personal IC card 61 is energized and the personal IC card 61 is On the other hand, when the user specified by fingerprint authentication is not a person who has the personal IC card 61, the read fingerprint is written in the common IC card 61, and the IC card 61 in which the data is written is supported. By energizing the solenoid 100, the IC card 61 can be taken out. Therefore, the digital key box 60 can reduce the number of IC cards 61 to be managed and make the digital key box 60 compact as compared with the case of managing the personal IC card 61 individually given to the user.

Note that the digital key box 60 can be configured so that the common IC cards 61 are grouped according to conditions (user attributes, frequency with which the user uses the IC card 61, time zone in which the IC card 61 is used, etc.). The common IC card 61 can be lent out under different conditions, and the shortage of the common IC card 61 can be avoided.
If the valid time is written in the IC card 61, the IC card 61 loses its function as a key after the valid time elapses, so that the risk of unauthorized use of the IC card 61 can be avoided.

  The digital key box 60 permits the IC card 61 to be taken out only from the storage device 90A, for example, by releasing the lock means 105 of the specific storage device 90A when authority authentication is successful by fingerprint authentication. The IC card 61 is not taken out without permission. Therefore, by storing a plurality of IC cards 61 using the digital key box 60, the IC cards 61 can be strictly managed.

  The digital key box 60 of the second embodiment writes biometric information used in common to the authentication unit 70 and the authentication of the vault into the IC card 61. Therefore, if the authentication unit 79 is provided with the fingerprint reading means 71 for reading the fingerprint, it is not necessary to provide the fingerprint reading means on the storage side, and the cost of the storage can be reduced.
