It relates to a key management box having a key locking means to which the common key is attached and cannot be taken out.

In a private lodging where multiple rooms are used as accommodation facilities among the rooms arranged in the condominium, it is necessary to hand over the key for unlocking the lock of the room to the user.
The manager of the private lodging can hand over the key by handing it directly to the user, but it takes time and effort because the manager and the user have to keep in touch and meet. It is also possible to hand over the key by putting the key in the locked mailbox and the administrator telling the user how to unlock the mailbox, but the mailbox is destroyed by a third party. The key may be taken out and security cannot be guaranteed.

As a system for eliminating the trouble and time of the administrator and ensuring security when handing over the keys, in order to unlock the locks of multiple rooms located in the accommodation facility, to multiple users of the accommodation facility A key management box can be used for centrally storing and managing the common keys used, and having a key locking means to which the common key is attached and cannot be taken out.
For example, Patent Document 1 by the applicant of the present application has personal authentication means, and when the personal authentication means recognizes a specific user, the storage specific data for which the recognized user has unlocking permission is provided. A key management box having a writing means for writing to an IC tag having a common key is disclosed, and a user can use a common key in which the vault specific data is written to use a vault that has unlocking permission. The lock can be unlocked.

That is, the user of the private lodging uses the reservation confirmation means of the key management box to confirm the reservation information by using a smartphone or the like. When the reservation confirmation means confirms the reservation, the writing means writes the specific data for which the user has the unlock permission (that is, the specific data of the reserved room) in the IC tag having the common key. The user can unlock the lock of the reserved room by using the common key in which the specific data of the reserved room is written.

Japanese Patent No. 5456463

The applicant of the present application has proposed an electric lock of Japanese Patent Application No. 2018-029898 as a lock for a private lodging room. The electric lock is an electric lock that has an automatic locking means and can be retrofitted to the door by removing the thumb turn existing on the door. Here, the automatic locking means is for performing a locking operation and waiting in a locked state when it is detected that the door of the room is closed. By using the electric lock, the private room can be automatically locked. The purpose of auto-locking is to prevent third parties from entering the room and to ensure the same level of security as a hotel.

However, the conventional key management box has the following problems.
If the user forgets the common key indoors and goes out of the room, or if the common key is lost outdoors, the electric lock is automatically locked because it has an automatic locking means and is locked out of the room. ..
In this case, if the hotel has a front desk, the hotel employee can be requested to unlock with the master key and re-enter the room. At this time, the employee can memorize the user's face at the time of check-in or confirm personal information such as name, address, date of birth, etc., so he requested unlocking with the master key. It is possible to confirm that the person is the user himself / herself. Therefore, there is no risk of a third party entering the user's room with the master key, and security is ensured.

On the other hand, in private lodging, the key is handed over in the key management box, so if there is no front desk and the user leaves the common key in the room and goes out of the room, the master key is used like a hotel. It is not possible to take such measures.
Further, if the user forgets the smartphone together with the common key indoors and goes out of the room, the user has no means to confirm the reservation in the key management box and receive the common key again.
Therefore, there is a need for a key management box that has a system that replaces the front desk of the hotel and can re-provide the common key while ensuring security.

The present invention is for solving the above-mentioned problems, and when a user of an accommodation facility further needs a common key, a key management box capable of re-providing the common key while ensuring security. The purpose is to provide.

In order to solve the above problems, the key management box of the present invention has the following configuration.
(1) In order to unlock the electric locks of a plurality of rooms arranged in the accommodation facility, the common key used by a plurality of users of the accommodation facility is centrally stored and managed, and is common. In a key management box having a key locking means to which a key is attached and cannot be taken out, the electric lock automatically locks and waits in the locked state when it detects that the door of the room is closed. Having a locking means, the key management box acquires the user's personal authentication information when the reservation is confirmed by the reservation confirmation means and the reservation confirmation means that confirms the information of the accommodation reservation made by the user. The personal authentication information acquisition means, the storage means for storing the personal authentication information acquired by the personal authentication information acquisition means, and the electricity of the room reserved by the user in the common key when the storage of the personal authentication information is completed. A room reserved by the user, which has an authorization means for granting the unlocking authority for unlocking the lock and a control means for releasing the key locking means when the unlocking authority is granted. The user made a reservation when the common key to which the unlocking authority was granted was left behind in the room and the room reserved by the user was locked by the automatic locking means of the electric lock. It is characterized by having a re-providing means for re-providing a common key having an unlocking authority to unlock an electric lock in a room.

(2) In the key management box described in (1), the re-provision means has the unlocking authority to unlock the electric lock of the room reserved by the user when the reservation confirmation is performed again in the reservation confirmation means. It is characterized by re-providing a common key having.
(3) In the key management box described in (1), the key management box is stored in the personal authentication information acquired again and the storage means when the personal authentication information is acquired again by the personal authentication information acquisition means. It has a collation means for collating the personal authentication information, and the re-provision means makes a reservation by the user when the personal authentication information acquired again in the collation means and the personal authentication information stored in the storage means match. It is characterized by re-providing a common key having the unlocking authority to unlock the electric lock in the room.

(4) In the key management box described in any one of (1) to (3), the user can select whether to receive the common key for the first time or to receive the common key again. Having a capable operating means, the user can select the first option of having the personal authentication information acquisition means acquire the personal authentication information and the second option of not causing the personal authentication information acquisition means to acquire the personal authentication information. That is, when the user selects the second option, the common key is not re-provided by the re-provision means.

(5) In the key management box according to any one of (1) to (4), when the electric lock is unlocked by using the re-provided common key, it is provided before the re-provision. It is characterized in that the electric lock cannot be unlocked using a common key.
(6) In the key management box according to any one of (1) to (4), the unlocking authority given to the re-provided common key is valid only for a predetermined time. .. If the common key is re-provided by the re-providing means, the user may take the re-provided common key home and re-enter the room on a day different from the reserved period of the room, and the common key may be misused. Since there is a problem that it is difficult to guarantee security, the unlocking authority is valid for a certain period of time.

(7) In the key management box according to any one of (1) to (6), the personal authentication information acquisition means is at least one of face authentication, fingerprint authentication, vein authentication, iris authentication, voiceprint authentication, and handwriting authentication. It is characterized in that personal authentication information is acquired by one of the methods.

The key management box of the present invention has the following actions and effects by having the above configuration.
(1) In order to unlock the electric locks of a plurality of rooms arranged in the accommodation facility, the common key used by a plurality of users of the accommodation facility is centrally stored and managed, and is common. In a key management box having a key locking means to which a key is attached and cannot be taken out, the electric lock automatically locks and waits in the locked state when it detects that the door of the room is closed. Having a locking means, the key management box acquires the user's personal authentication information when the reservation is confirmed by the reservation confirmation means and the reservation confirmation means that confirms the information of the accommodation reservation made by the user. The personal authentication information acquisition means, the storage means for storing the personal authentication information acquired by the personal authentication information acquisition means, and the electricity of the room reserved by the user in the common key when the storage of the personal authentication information is completed. A room reserved by the user, which has an authorization means for granting the unlocking authority for unlocking the lock and a control means for releasing the key locking means when the unlocking authority is granted. The user made a reservation when the common key to which the unlocking authority was granted was left behind in the room and the room reserved by the user was locked by the automatic locking means of the electric lock. Since it is characterized by having a re-providing means for re-providing a common key having the unlocking authority to unlock the electric lock in the room, the electric lock is automatically used, for example, when the user goes out without having the common key. Even if the lock is automatically locked by the locking means and the user is locked out of the room, the user can receive the common key again by the means of re-providing the key management box.

(2) In the key management box described in (1), the re-provision means has the unlocking authority to unlock the electric lock of the room reserved by the user when the reservation confirmation is performed again in the reservation confirmation means. Since it is characterized by re-providing a common key with a common key, for example, when the user goes out without having a common key, the automatic lock is performed by the automatic locking means of the electric lock, and the user is locked out of the room. However, if the user has a smartphone, the reservation can be confirmed by the reservation confirmation means of the key management box using the QR code (registered trademark) that stores the reservation information stored in the smartphone. When the reservation is confirmed, the re-provision means re-provides a common key having the unlocking authority to unlock the electric lock of the room reserved by the user, and the user can enter the reserved room. Confirming a reservation by means of reservation confirmation in order to re-provide the common key is the same as confirming personal information such as name at the front desk of the hotel when using the master key, ensuring security. be able to.

(3) In the key management box described in (1), the key management box is stored in the personal authentication information acquired again and the storage means when the personal authentication information is acquired again by the personal authentication information acquisition means. It has a collation means for collating the personal authentication information, and the re-provision means makes a reservation by the user when the personal authentication information acquired again in the collation means and the personal authentication information stored in the storage means match. Since it is characterized by re-providing a common key that has the unlocking authority to unlock the electric lock in the room, for example, the user rushes to chase the child and goes outdoors without carrying the smartphone with the common key. Even if it comes out, the key management box confirms the reservation by the reservation confirmation means at the time of check-in, the personal authentication information acquisition means acquires the personal authentication information, and the storage means stores the personal authentication information. Therefore, if the user causes the personal authentication information acquisition means of the key management box to acquire the personal authentication information again, and the personal authentication information and the personal authentication information stored by the storage means at the time of check-in match by the collation means, The re-provision means re-provides a common key that has the unlocking authority to unlock the electric lock in the room reserved by the user. Personal authentication is the same as using the master key after the front desk employee remembers the user's face and confirms that he / she is the user, and security can be ensured. ..

(4) In the key management box described in any one of (1) to (3), the user can select whether to receive the common key for the first time or to receive the common key again. Having a capable operating means, the user can select the first option of causing the personal authentication information acquisition means to acquire the personal authentication information and the second option of not causing the personal authentication information acquisition means to acquire the personal authentication information. That is, when the user selects the second option, the common key is not re-provided by the re-provision means. Therefore, for example, if the touch panel is used as the operation means, the check-in is performed by the touch panel. The convenience of operating the key management box can be improved by allowing the user to select whether to perform the authentication or to receive the re-provision of the common key. Furthermore, if the user does not want the key management box to acquire personal authentication information, by selecting the second option, the key management box can be provided with a common key without acquiring personal authentication information. it can. Therefore, it is possible to consider the emotions of the user. However, even when the user needs to re-provide the common key, the personal authentication information cannot be collated by the collation means because the key management box does not acquire the personal authentication information. Therefore, the common key is not re-provided by the re-providing means, and security can be ensured.

(5) In the key management box according to any one of (1) to (4), when the electric lock is unlocked by using the re-provided common key, it is provided before the re-provision. The feature is that the electric lock cannot be unlocked using the common key. Therefore, if the electric lock is unlocked with the re-provided common key, the room in which the provided common key is reserved before the re-provision. Even if it is inserted into the electric lock, it cannot be unlocked and loses its function as a key. For example, even if the user loses the common key provided before re-provision and a third party picks up the lost common key, the room reserved by the user using the re-provided common key. After unlocking the electric lock, it is possible to prevent unauthorized use such as entering the room reserved by the user by using the common key picked up by the third party.
(6) In the key management box according to any one of (1) to (4), the unlocking authority given to the re-provided common key is valid only for a predetermined time. Therefore, the common key re-provided from the key management box cannot be unlocked even if it is inserted into the electric lock of the reserved room after the valid time has passed, and loses its function as a key. Since the re-provision of the common key is performed as an extremely means when the user is locked out by the automatic locking means of the electric lock, a valid time for re-provision is set and the re-provided common key is provided. Prompt return can be encouraged.

(7) In the key management box according to any one of (1) to (6), the personal authentication information acquisition means is at least one of face authentication, fingerprint authentication, vein authentication, iris authentication, voiceprint authentication, and handwriting authentication. It is characterized in that personal authentication information is acquired by one of the methods. At least one of the user's face, fingerprint, vein, iris, voiceprint, and handwriting is acquired by personal authentication information and stored in a storage means. In order for the key management box to re-provide the common key, the memorized face, fingerprint, vein, iris, voiceprint, and the same face, fingerprint, vein, iris, voiceprint, and handwriting as the handwriting are read by the personal authentication information acquisition means. Must be matched by matching means. Since no one has the exact same face, fingerprint, vein, iris, voiceprint, or handwriting as the user, it will be stolen by a third party such as a QR code or barcode, and authentication will be performed by the third party. There is no danger and security is guaranteed. In addition, by ensuring security, residents other than the rooms used as private lodgings in the condominium can feel secure. In practice, many users avoid fingerprint authentication, and it is preferable to acquire personal authentication information by face authentication. When using a private lodging, the staying period is short and the appearance of the user does not change significantly. Therefore, rather than collating the user with a photo that has passed several years like a passport photo, the face image acquired by the key management box at check-in and the key management box when the electronic key 1 is re-provided. The matching of the face images acquired by 50 is easy to match.

The rotating shaft 48 rotates according to the rotational force transmitted from the first and second pressing portions 351 and 352 to the first and second engaging projecting pieces 482 and 483. The width of the first engaging projecting piece 482 and the second engaging projecting piece 483 in the rotational direction is smaller than the distance between the first pressing portion 351 and the second pressing portion 352. Therefore, the rotating shaft 48 is affected by the resistance generated by the driving force transmitting unit 29 without engaging with the thumb turn gear member 35 as long as it is within the range between the first pressing unit 351 and the second pressing unit 352. Can rotate without. In this case, since the resistance generated in the gear train of the driving force transmitting unit 29 does not act on the rotating shaft 48 via the thumb turn gear member 35, the thumb turn 25 can be rotated with the same force as the existing thumb turn. it can.

As shown in FIGS. 8 and 9, in the electric lock 20, a lock position detection switch 45, an unlock position detection switch 46, and a standby position detection switch 47 are mounted in the main body cover 24. The locking position detecting switch 45 and the unlocking position detecting switch 46 are arranged outside the thumb turn gear member 35, and the switch pieces 45a and 46a are pressed against the second engaging projecting piece 483. The lock position detection switch 45 and the unlock position detection switch 46 are turned on when the switch pieces 45a and 46a are pressed by the second engaging projecting piece 483, respectively, and the switch pieces 45a and 46a are in the second engagement. If it is not pressed by the collision piece 483, it is turned off.

Further, as shown in FIG. 7, a gear 48a is provided at the end of the rotating shaft 48 on the key cylinder 23 side and is meshed with the gear cam 49. When the rotating shaft 48 rotates, the gear cam 49 is passed through the gear 48a. Rotates. Therefore, when the rotating shaft 48 rotates due to the driving force transmitted from the driving force transmitting unit 29, the rotating force for rotating the rotating shaft 48 is transmitted to the internal cam via the gear 48a and the gear cam 49, and the dead bolt protrudes. Alternatively, it can be retracted and can be locked or unlocked.

As shown in FIG. 7, the first unit 21 and the second unit 22 are provided with fitting portions 211 and 221 fitted into the thumb turn mounting holes D1. The fitting portions 211 and 221 are provided with pin insertion holes 211a and 221a into which the fixing pins that have fixed the existing thumb turns of the door D are inserted. In the electric lock 20, the fixing pin that fixed the existing thumb turn is removed from the door D, and the fitting portions 211 and 221 are fitted into the thumb turn mounting holes D1 to which the existing thumb turn is mounted, and the fitting portions 211 and 221 are inserted into the pin insertion holes 211a and 221a. By inserting the fixing pin and attaching it to the door D, it can be retrofitted to the door D.

Next, the electrical configuration of the electric lock 20 will be described with reference to FIG.
The electric lock 20 has a motor 26, a data reading means 41, a door position detecting means 44, a locking position detecting switch 45, an unlocking position detecting switch 46, and a standby position detecting switch 47 on a control board 31. It is connected. Further, the control board 31 includes a CPU 311, a ROM 312, a RAM 313, an NVRAM 314, and a timer 315.

The ROM 312 includes an unlocking permission program 312a that permits unlocking of the electric lock 20 when the electronic key 1 is authenticated, and an automatic locking program 312b that automatically locks when the door D is detected to be closed. Automatic locking means) is stored. The NVRAM 314 has a room number information storage unit 314a and a control number storage unit 314b. The room number information storage unit 314a stores the room number information to which the electric lock 20 is attached. Further, the control number storage unit 314b stores the control number stored in the control number storage means 10 of the electronic key 1 read by the data reading means 41.
The CPU 311 controls the operation of the electric lock 20 while storing data in the NVRAM 314 according to the program stored in the ROM 312. The CPU 311 can also control the electric lock 20 while measuring the time with the timer 315.
In the automatic locking program 312b, when the door position detecting means 44 detects that the door D is closed, the motor 26 rotates the thumb turn 25 to the locking position where the door D is locked to automatically lock the door D. When the door D is closed, the electric lock 20 always stands by in the locked state.

Next, the outline of the operation of the electric lock 20 will be described.
When the electric lock 20 stands by in the locked state, the lock position detection switch 45 is on, the unlock position detection switch 46 is off, and the standby position detection switch 47 is on. On the other hand, when the electric lock 20 stands by in the unlocked state, the lock position detection switch 45 is in the off state, the unlock position detection switch 46 is in the on state, and the standby position detection switch 47 is in the on state.

The electric lock 20 rotates the motor 26 when the door position detecting means 44 detects that the door D has been closed by the automatic locking program 312b. The rotational force of the motor 26 is transmitted to the thumb turn gear member 35 via the worm gear 32 and the reduction gear member 33, and the thumb turn gear member 35 starts to rotate in the locking direction. The thumb turn gear member 35 rotates to a position where the pressing surfaces 351a and 352a at the time of locking are brought into contact with the first and second engaging projectiles 482 and 483, respectively, and then further rotates in the locking direction. The thumb turn 25 and the key cylinder 23 are transmitted a rotational force in the locking direction from the thumb turn gear member 35 via the first and second engaging projecting pieces 482, 483 of the rotating shaft 48, and from the unlocked position toward the locked position. It starts to rotate. The electric lock 20 stops the motor 26 when the lock position detection switch 45 is turned on. As a result, the thumb turn 25 and the key cylinder 23 are arranged at the locked positions, and the door D is locked. By performing auto-locking with the automatic locking program 312b, it is possible to prevent a third party from entering the room. Therefore, by retrofitting the electric lock 20 to the door D, it is possible to ensure the same security as a hotel even in a private room.

In this state, the first and second engaging projecting pieces 482 and 483 are in contact (engaged) with the pressing surfaces 351a and 352a at the time of locking. Therefore, even if the thumb turn 25 is turned to unlock it, the resistance generated in the meshing portion between the worm gear 32 and the first gear 331 and the meshing portion between the second gear 332 and the gear of the thumb turn gear member 35 is generated in the thumb turn gear member. It acts on the rotating shaft 48 via 35, and the thumb turn 25 cannot be turned. Therefore, the electric lock 20 enters the standby state after rotating the motor 26 in the direction opposite to that at the time of locking and turning the thumb turn gear member 35 back by 90 degrees. In this standby state, the first and second pressing portions 351 and 352 are not in contact (engaged) with the locking pressing surfaces 351a and 352a of the first and second pressing portions 351 and 352. Therefore, when the thumb turn 25 or the key cylinder 23 is manually rotated to unlock, it occurs in the meshing portion between the worm gear 32 and the first gear 331 and the meshing portion between the second gear 332 and the gear of the thumb turn gear member 35. The resistance does not act on the rotating shaft 48 via the thumb turn gear member 35. That is, the thumb turn 25 and the key cylinder 23 receive only the sliding resistance generated between the rotating shaft 48 and the thumb turn gear member 35, and can rotate with a small rotational torque. Therefore, when the electric lock 20 cannot be used due to a power failure, for example, the user can turn the thumb turn 25 or the key cylinder 23 with a light force to unlock the lock.

Subsequently, the operation procedure of the electric lock 20 will be described with reference to FIG.
When the user intends to unlock the electric lock 20, the electric lock 20 stands by in a locked state by the automatic locking program 312b. When the user inserts the electronic key 1 into the electric lock 20, the data reading means 41 reads the room number information stored in the electronic key 1, and the CPU 311 reads the read room number information into the room number of the NVRAM 314. The authority is authenticated by collating with the room number information stored in the information storage unit 314a (S11). If the read room number information does not match the room number information stored in the room number information storage unit 314a and the authentication fails (S12; NO), there is a possibility of a reading error or the like. After the error notification is performed (S25), the error notification history is stored in the history storage unit 314c of the NVRAM 314 (S23), and the process ends. The error notification may be performed by a buzzer, voice, or the like, or may be displayed by a lamp or the like, and when the electric lock 20 is connected to a device provided with a display unit, an error message is displayed on the display unit. You may notify by letting you.

When the collation of the room number information matches (S12; YES), the data reading means 41 reads the control number stored in the control number storage means 10 of the electronic key 1, and the CPU 311 reads the read control number. The control number stored in the control number storage unit 314b of the NVRAM 314 is collated (S13). When the read control number matches the control number stored in the control number storage unit 314b (S14; YES), the unlock permission program 312a grants unlock permission, and the key cylinder 23 becomes rotatable (S15). If the read control number is larger than the control number stored in the control number storage unit 314b, the control number stored in the control number storage unit 314b is rewritten to the larger number read. After that (S24), unlocking permission is given by the unlocking permission program 312a, and the key cylinder 23 becomes rotatable (S15). If the read control number is smaller than the control number stored in the control number storage unit 314b (S14; NO), the CPU 311 gives an error notification (S26), and then displays the error notification history. It is stored in the history storage unit 314c of the NVRAM 314 (S23), and the process ends.

As will be described later, each time the electronic key 1 is provided, the key management box 50 sets a number larger than the management number set at the time of the previous provision. Therefore, for example, when the user tries to enter the reserved room for the first time, the electric lock 20 stores the control number (hereinafter, the previous control number) assigned to the electronic key 1 used by the user last time. However, since the user's electronic key 1 is given a management number larger than the management number given to the user's electronic key 1 last time (hereinafter referred to as the provision management number), the user can use the electronic key 1. By inserting the electric lock 20, the previous management number stored in the electric lock 20 is rewritten to the provided management number (S24), and unlocking permission is given (S15). Therefore, even if the user illegally brings back the electronic key 1 last time, even if the electronic key 1 having the control number last time is inserted into the electric lock 20, authentication is not performed and the lock cannot be unlocked (S14; NO).

When the user enters the reserved room for the second time or later, the electric lock 20 stores the provision management number, so that the electric lock 20 is collated with the provision management number of the user's electronic key 1 (S14; (Same number), unlocking permission is given (S15).

Further, when the user receives the re-provision of the electronic key 1, the re-provided electronic key 1 is given a management number larger than the provision management number (hereinafter referred to as the re-provision management number). By inserting the electronic key 1 re-provided by the person into the electric lock 20, the provision control number stored in the electric lock 20 is rewritten to the re-provision control number (S24), and unlocking permission is given (S15). .. Therefore, even if the electronic key 1 having the new control number is inserted into the electric lock 20, authentication is not performed and the lock cannot be unlocked (S14; NO). Therefore, after the electronic key 1 is re-provided, the re-provided electronic key is provided. Use 1 to enter and leave the room.

Since the electric lock 20 has an automatic locking program 312b, when the user opens the door D (S16), enters the room, and then the door position detecting means 44 detects that the door D is closed (S17; YES), the CPU 311 Rotates the motor 26 in the locking direction (S18). The rotational force of the motor 26 causes the thumb turn 25 to rotate toward the locked position, and the rotational force applied to the thumb turn 25 is transmitted to the internal cam via the gear 48a and the gear cam 49, and the dead bolt connected to the internal cam. Projects from the door D and can be locked. By performing auto-locking with the automatic locking program 312b, it is possible to prevent a third party from entering the room. Therefore, by retrofitting the electric lock 20 to the door D, it is possible to ensure the same security as a hotel even in a private room.

The CPU 311 determines whether or not the locked position has been detected (S19). When the lock position detection switch 45 remains in the off state, the CPU 101 determines that the lock position is not detected, and continues to rotate the motor 26 in the lock direction (S19; NO). On the other hand, when the lock position detection switch 45 is switched from the off state to the on state to detect the lock position (S19; YES), the CPU 101 stops the motor 26.

After that, the CPU 311 inverts the motor 26 (S20). The CPU 311 determines whether the thumb turn gear member 35 has returned to the position immediately before the unlocking operation is started (S21). In the CPU311, when the lock position detection switch 45 is in the ON state, the detection lever 471 is disengaged from the fourth detection recess 353d, and when the standby position detection switch 47 is in the OFF state, the thumb turn gear member 35 is rotating. Yes, it is determined that the position immediately before the unlocking operation is started has not been restored (S21; NO).

On the other hand, when the locking position detection switch 45 is in the ON state, the CPU 311 is fitted into the third detection recess 353c after the detection lever 471 is disengaged from the fourth detection recess 353d, and the standby position detection switch 47 is in the ON state. When the switch is switched between the off state and the on state, it is determined that the thumb turn gear member 35 has been returned to the position immediately before the unlocking operation is started in S20 (S21; YES). In this case, the CPU 311 stops the motor 26 (S22). As a result, in the electric lock 20, the portions of the first and second engaging projecting pieces 482 and 483 located in the unlocking rotation direction do not abut (engage) with the first and second pressing portions 351 and 352. The door D is locked at, and the unit is in a standby state.

Then, the CPU 311 stores the lock / unlock history of the door D in the history storage unit 314c of the NVRAM 314 (S23), and ends the process.

<Electronic key management system>
A system for managing the electronic key 1 will be described.

It is connected to 54.

Next, the operation of the present embodiment will be described with reference to the flowcharts of FIGS. 14 to 16 and the display images of FIGS. 17 to 19.
First, the case where the user checks in to the private lodging will be described.
The user makes an accommodation reservation with the manager of the private lodging in advance using a personal computer, a smartphone, or a general telephone, and receives a QR code containing the reservation information from the manager. Up to this point, the key management box 50 is not used. In the standby state of the key management box 50, the display image 531 is displayed on the touch panel 53 as shown in FIG. 17A, and the user goes to the key management box 50 at the time of staying and displays it on the display image 531. Select check-in 531a from the options provided. Then, as shown in FIG. 17B, the display image 532 is displayed on the touch panel 53, and the user is made to read the QR code stored in the smartphone in advance by the CCD camera 54 so as to fit in the display frame 532a ( S31). The CPU 311 connects to the private lodging manager's server 72 (see FIG. 13) by the communication means 70, and collates the reservation information. When the reservation is confirmed (S32; YES), the display image 533 is displayed on the touch panel 53 as shown in FIG. 17 (c), and it is selected whether or not to take a picture of the user's face for personal authentication. can do. If the user approves the shooting of the face, the option 533a is selected (S33; YES). Then, as shown in FIG. 14D, the display image 534 is displayed on the touch panel 53, the user's face is photographed by the CCD camera 54, and the photographed user's face data is stored in the face recognition data storage unit 681. Is memorized by (S34).

After that, the room number information writing means 60 writes the room number information (unlocking authority) of the reserved room to the room number information storage means 9 of the arbitrary electronic key 1 (S35). Further, the control number writing means 61 writes the control number in the control number storage means 10 of the electronic key 1 (S36).
The management number is managed by the server 72 of the private lodging manager through the communication means 70, is an electronic key 1 used for the same room number, and is larger than the management number assigned to the electronic key 1 provided earlier. The control number of the number is set by the control number setting unit 676. Then, the control number having a large number is written by the control number writing means 61 in the control number storage means 10 of the electronic key 1 (for example, 10 as the control number in the electronic key 1 of the previous user who stayed in room 101). If a number is assigned, the electronic key 1 of the user staying in room 101 this time is set with a management number of 11 and assigned).

Next, the controller 65 opens the opening / closing door 51, and at the same time, displays the display image 535 on the touch panel 53 as shown in FIG. 17 (e), and the key 1 on which the arbitrary electronic key 1 in which the data is written is attached. The key locking means 58 of the hole unit 52 is released, and the LED 56 of the released key hole unit 52 is turned on (S37). Therefore, the user can pull out the predetermined electronic key 1. When the electronic key 1 is extracted and the IC tag data reading means 59 no longer detects the electronic key 1, the controller 65 determines that the electronic key 1 has been extracted from the key hole 55 (S38; YES) and is extracted. The electronic key 1 and the time taken out are stored in the history storage unit 682 (S39). After that, as shown in FIG. 17F, the display image 536 is displayed on the touch panel 53, and the user is instructed to close the opening / closing door 51 (S40). When it is confirmed that the opening / closing door 51 is closed (S41; YES), the electronic key providing program 671 at check-in ends, and the display image 531 is displayed on the touch panel 53 as shown in FIG. 17A. ..

Remembering personal credentials by facial recognition is similar to having a hotel employee remember the guest's face at check-in, and the key management box 50 acts like a hotel employee. Become. In this embodiment, the face authentication unit 64 is used as a means for acquiring personal authentication information, but even if personal authentication is performed by biometric authentication such as fingerprint authentication, face authentication, vein authentication, iris authentication, voiceprint authentication, and handwriting authentication. good.

If the user does not approve the shooting of the face, the option 533b in the display image 533 of FIG. 17C is selected (S33; NO). Then, the display image 547 of FIG. 17 (d-2) is displayed, and the reconfirmation is performed, noting that the electronic key 1 cannot be re-provided. If the user still does not approve the shooting of the face, the user can receive the electronic key 1 by selecting option 547a (S42; YES). However, for security reasons, the electronic key 1 cannot be re-provided by personal authentication, which will be described later.

The key management box 50 may provide not only the electric lock 20 of a specific room but also an electronic key 1 capable of unlocking the electric lock 20 of two or more of all the rooms available as accommodation facilities. It is possible. For example, when the user has already checked out and has to clean the room, the cleaner receives in advance a QR code containing information such as the cleaning schedule and the room to be cleaned from the administrator. .. When cleaning, the cleaning staff goes to the key management box 50 and has the CCD camera 54 of the key management box 50 read the QR code. The CPU 311 connects to the private lodging manager's server 72 (see FIG. 13) by the communication means 70, and collates the reservation information. When the reservation is confirmed, if there are a plurality of rooms requiring cleaning in the room number information storage means 9 of any electronic key 1 by the room number information writing means 60, all the room number information (unlocking authority). Is written. If there are multiple rooms that need to be cleaned, it is a detour that the cleaner must go to the key management box 50 and receive the electronic key 1 every time one room is cleaned, so one electronic device. It is practical to be able to unlock the electric lock 20 in all the rooms that need to be cleaned with the key 1.

Next, a case where the user receives the re-provision of the electronic key 1 will be described.
If the user forgets the electronic key 1 indoors and goes out of the room, or if the electronic key 1 is lost outdoors, the electric lock 20 is automatically locked by the automatic locking means, so that the electronic key 1 is locked out. In this case, the case 1 in which the user carries the smartphone and the case 2 in which the user misplaces the smartphone and does not carry it will be described separately.

<Case 1>
If the user carries a smartphone, the user uses the smartphone to contact the administrator of the private lodging, and the administrator issues a new QR code for re-providing the electronic key, which is different from the QR code used at check-in. receive. Up to this point, the key management box 50 of the present invention is not used. Next, the user goes to the key management box 50 and selects "key re-provision" 531c from the options displayed in the display image 531 (FIG. 17A). Then, since the display image 537 is displayed on the touch panel 53 as shown in FIG. 18A, the option “Yes” 537a is selected in order for the key management box 50 to read the new QR code for re-providing the electronic key. (S51; YES).

Then, as shown in FIG. 18 (b-1), the display image 538 is displayed on the touch panel 53, and the user puts the new QR code saved in the smartphone on the CCD camera 54 so as to fit in the display frame 538a. Read (S52). The CPU 311 connects to the private lodging manager's server 72 (see FIG. 13) by the communication means 70, and collates the reservation information. When the reservation is confirmed (S53; YES), the room number information of the reserved room is given to the arbitrary electronic key 1 by the room number information writing means 60 (S54). Next, a new control number set by the control number setting unit 676 is written in the control number storage means 10 of the electronic key 1 by the control number writing means 61 (S55).

The management number is managed by the server 72 of the private lodging manager through the communication means 70, and is the electronic key 1 used for the same room number, and the management assigned to the electronic key 1 provided before the re-provision. A control number having a number larger than the number is set by the control number setting unit 676. Then, the control number having a large number is written by the control number writing means 61 in the control number storage means 10 of the electronic key 1 (for example, as a control number in the electronic key 1 provided when the user checks in). If the number 10 is assigned, the number 11 is set and assigned as the control number to the electronic key 1 to be re-provided).

At the same time as opening the opening / closing door 51, the controller 65 displays the touch panel 53 display image 539 as shown in FIG. 18 (c-1), and the key hole unit 52 to which an arbitrary electronic key 1 into which data is written is mounted. The key locking means 58 of the above is released, and the LED 56 of the released key hole unit is turned on (S56). Therefore, the user can pull out the predetermined electronic key 1. When the electronic key 1 is extracted and the IC tag data reading means 59 no longer detects the electronic key 1, the controller 65 determines that the electronic key 1 has been extracted from the key hole 55 (S57; YES) and is extracted. The electronic key 1 and the time taken out are stored in the history storage unit 682 (S58). After that, as shown in FIG. 18D, the display image 540 is displayed on the touch panel 53, and the user is instructed to close the opening / closing door 51 (S59). When it is confirmed that the opening / closing door 51 is closed (S60; YES), the electronic key re-provision program 672 by the QR code is terminated, and the display image 531 is displayed on the touch panel 53 as shown in FIG. 17A. Will be done.

<Case 2>
Next, a case where the user misplaces the smartphone in the room and does not carry it will be described. If the user does not carry a smartphone, it is difficult to contact the private lodging manager and he / she will not be able to receive a new QR code for re-providing the electronic key 1, but by the following method , The electronic key 1 can be re-provided in the key management box 50.
The user goes to the key management box 50 and selects "key re-provision" 531c from the options displayed in the display image 531 (FIG. 17 (a)). Then, as shown in FIG. 18A, the display image 537 is displayed on the touch panel 53, and the option “No” 537b is selected (S51; NO).
As shown in FIG. 18 (b-2), the display image 541 is displayed on the touch panel 53, and the face of the user is photographed by the CCD camera 54 (S61).
The user's face data taken at check-in stored by the face recognition data storage unit 681 is collated with the user's face data taken by S24, and if the face data match, (S62; YES), the room number information writing means 60 writes the room number information of the reserved room to the room number information storage means 9 of the arbitrary electronic key 1 (S54).

Next, the control number set by the control number setting unit 676 is written in the control number storage means 10 of the electronic key 1 by the control number writing means 61, and the opening / closing door 51 is opened. At the same time as opening the opening / closing door 51, the controller 65 displays a display image 542 on the touch panel 53 and a key hole in which an arbitrary electronic key 1 into which data is written is mounted, as shown in FIG. 18 (c-2). The key locking means 58 of the unit 52 is released, and the LED 56 of the released key hole unit 52 is turned on (S56). Therefore, the user can pull out the predetermined electronic key 1.

In order for the key management box 50 to re-provide the common key 1, the exact same face as the stored face is read by the personal authentication information acquisition means (consisting of the CCD camera 54 and the face recognition unit 64) and matched by the matching means. Must be (S61, S62 in FIG. 15). Since no one has the exact same face as the user, there is no risk of being stolen by a third party such as a QR code or barcode and being authenticated by a third party, and security is guaranteed. .. In addition, by ensuring security, residents other than the rooms used as private lodgings in the condominium can feel secure.

As the personal authentication information acquisition means, in addition to face authentication, personal authentication information can be acquired by at least one of fingerprint authentication, vein authentication, iris authentication, voiceprint authentication, and handwriting authentication. In practice, many users avoid fingerprint authentication, and it is preferable to acquire personal authentication information by face authentication. When using a private lodging, the staying period is short and the appearance of the user does not change significantly. Therefore, rather than collating the user with a photo that has passed several years like a passport photo, the face image acquired by the key management box at check-in and the key management box when the electronic key 1 is re-provided. The matching of the face images acquired by 50 is easy to match.

As another embodiment, when the user is a group customer, the key management box may be able to provide a number of electronic keys 1 according to the number of group customers.
When a user makes an accommodation reservation with a private lodging manager in advance using a personal computer, smartphone, or general telephone, the number of guests is notified, and the manager stores the reservation information and the number of guests.

When the user causes the key management box 50 to read the QR code at check-in, the electric lock of the room reserved by the authorization means 60 is unlocked on the electronic keys 1 for the number of guests based on the read information on the number of guests. The unlocking authority is granted, and when the unlocking authority is granted, the control means 65 can release the key locking means 58 of the electronic key 1 for the number of people so that the electronic key 1 can be provided. deep. Further, at the time of check-in, each group guest stores the face recognition information in the storage means 69 of the key management box 50, so that each person individually needs to provide the electronic key 1 again. Is made to read the face recognition information into the key management box 50 again, and if the verification matches, each person can individually receive the re-provision of the electronic key 1.
According to this embodiment, the group guests can receive the electronic keys 1 for the number of guests in the same way that the front desk of the hotel provides the keys for the number of rooms according to the number of guests.

On the other hand, in a private lodging, it is possible that a large amount of electronic keys 1 cannot be stocked in the key management box 50 from the viewpoint of cost. In that case, the key management box 50 provides one electronic key 1 to the group customer. Then, when all the group customers go out, the electronic key 1 is returned to the key management box 50. By returning it, even if a group guest takes individual action on the go and one of them returns to the private lodging, he / she can enter the room if the electronic key 1 is provided by the key management box 50. It is no longer necessary to provide the electronic key 1 for the minute. Further, returning the electronic key 1 to the key management box 50 when going out is the same as depositing the key at the front desk when going out at the hotel, and security can be ensured.

It should be noted that the present embodiment is merely an example and does not limit the present invention in any way. Therefore, as a matter of course, the present invention can be improved and modified in various ways without departing from the gist thereof.
