It relates to a key management box having a key locking means that makes it impossible to retrieve.

In the student dormitory, insurance is used to deal with problems in the student dormitory, such as replacing lamps, repairing home appliances, and repairing furniture and other fixtures. When a resident of a student dormitory asks a contractor to deal with the above problems in the student dormitory, the resident must be at home to attend the work. In addition, if the resident is requesting delivery of the package, the resident must be at home to receive the package. However, when the resident was absent due to circumstances, it was necessary to readjust the work schedule for troubleshooting in the student dormitory and to redeliver the package for delivery. Therefore, in order to be able to deal with troubles in the student dormitory and deliver luggage even when the resident is absent, it is necessary to hand over the key to unlock the lock of the room to the work and delivery company. ..

The student dormitory manager can hand over the keys by handing them directly to the contractor, but it takes time and effort because the student dormitory manager and the contractor have to keep in touch and meet. Alternatively, the resident can hand over the key by handing it directly to the contractor, but the resident is absent from the dormitory because he has errands, so there is time to hand it over directly. If so, you can wait for the contractor to visit the room, and waiting for the visit will prevent the key from being misused. In addition, the key can be handed over by putting the key in the locked mailbox and telling the trader how to unlock the mailbox, but the mailbox is destroyed by a third party and the key is taken out. There is a risk that security cannot be guaranteed.

It is possible to use a key management box for centrally storing and managing the keys, which has a key locking means to which the common key is attached and cannot be taken out.
For example, Patent Document 1 has a personal authentication means, and when the personal authentication means recognizes a specific user, the common key has vault specific data for which the recognized user has unlocking permission. A key management box having a writing means for writing to an IC tag is disclosed, and a user unlocks a lock of a storage having unlocking permission by using a common key in which the storage specific data is written. can do.

In other words, it is agreed that the contractor who works and delivers when the resident is absent is a person who has previously agreed with the resident to enter the room when he is absent, such as by using a smartphone. Perform by confirmation means. When the agreement confirmation means recognizes that the contractor is the person who has received the agreement, the writing means of the resident's room where the recognized contractor has the unlocking permission specific data (that is, the resident's room which has agreed to enter the contractor). Specific data) is written in the IC tag having the common key. The contractor can unlock the lock of the room for which the resident has agreed to enter the room by using the common key in which the specific data of the room for which the resident has agreed is written.

Japanese Patent No. 5456463

However, the conventional key management box has the following problems.
If the contractor visits the resident's room when the resident is absent, the resident cannot know what kind of person entered the room. In addition, if the visiting contractor accidentally finds money left in the room, the room may be damaged by stealing it. Furthermore, the resident cannot be sure that the contractor who visited the room has left the room, and the resident may have a chance to meet with the contractor in the room when returning home. Especially when the resident is a woman, unless the above problems are resolved, there is a great deal of anxiety about the contractor visiting the resident's room when the resident is absent, and the replacement of the lamp in the student dormitory There is a possibility that it will not be possible to utilize insurance to deal with problems in the student dormitory, such as repairing home appliances and furniture and other fixtures.

In addition, since the above-mentioned problems with conventional key management boxes are related to the safety of residents in student dormitories, it is not possible for manufacturers to leave them aware of the problems and continue manufacturing key management boxes.

It permits access to the storage means 9, the control number storage means 10, the effective time data storage means 11, and the history storage means 12.
The electronic key ID storage means 8 stores the "electronic key ID". Here, the electronic key ID means a unique identification number for identifying the electronic key 1. In this embodiment, the unique identification number of the contact type IC tag 5 is stored in the electronic key ID storage means 8 as an “electronic key ID”. There is no IC tag 5 having the same identification number in the world, and it is difficult to rewrite the identification number. Therefore, the electronic key 1 can be distinguished from other electronic keys 1 by using the identification number of the IC tag 5 as it is, without the trouble of assigning and storing individual identification numbers at the time of manufacturing.

The room number information storage means 9 reads and writes room number information that identifies the room R that has been agreed to be entered by a contractor who is an outside user among the plurality of rooms in the student dormitory. Further, the management number storage means 10 stores the management number set by the management number setting unit 974 of the key management box 80.

The effective time data storage means 11 stores effective time data indicating an effective time during which the electric lock 20 of the room R can be unlocked by using the room number information. The valid time data is written in the valid time data storage means 11 when the electronic key 1 is taken out from the key management box 80.
When the electric lock 20 of the room R is unlocked by using the electronic key 1, the history storage means 12 writes the identification number of the room R, the usage history such as the unlocked date and time, and the electronic key 1 is used as a key. The usage history is read into the key management box 80 when it is returned to the management box 80.

The external communication interface means 7 is a means for reading / writing data to / from the IC tag 5 (for example, a data reading means 42 for the electric lock 20 and an IC tag data reading means 90 for the key management box 80, a room number information writing means 91, which will be described later. It controls communication with the control number writing means 92, the effective time data writing means 99, etc.). The means for reading and writing the data comes into contact with the first and second terminals 5a and 5b, and reads and writes data to the IC tag 5.

The wiring 33 is arranged in the hollow portion of the slide shaft 34 so as not to hinder the slide of the slide shaft 34 and the holding shaft 35. In the present embodiment, the keyhole internal contact member 31, the wiring 33, and the keyhole external contact member 32 constitute a "contact means" that is held by the "shaft" and comes into contact with the electronic key 1 inserted into the keyhole 26a. There is.

As shown in FIG. 9, the inner cylinder 26 is integrated by connecting the first holder 261 and the second holder 262, the third holder 263, and the back plate 27 with a connecting bolt 264. It was done. Further, as shown in FIGS. 7 and 8, a slide shaft 34 is connected to the back plate 27 so that the inner cylinder 26 and the slide shaft 34 operate integrally. A slide shaft 34 is connected to the back plate 27 so that the inner cylinder 26 and the slide shaft 34 operate integrally.

In the second unit 22, a gear cam 49 connected to an internal cam (not shown) is rotatably held in the housing 41. In the cam member 48, the cylindrical portion 48c is loaded into the gear cam 49, and the cam member 48 is held by the cylindrical portion 50a of the shaft socket 50 internally provided in the housing 41, and rotates about an axis or reciprocates linearly along the axis. You can do it.

In the second unit 22, the slide shaft 34 and the holding shaft 35 are inserted into the shaft socket 50 from the gear cam 49 via the cam member 48, and the keyhole outer contact member 32 is arranged in the shaft socket 50. ..

In the second unit 22, a reset lever 51 is arranged on the side opposite to the inner cylinder 26 with the slide shaft 34 and the holding shaft 35 interposed therebetween. The reset lever 51 is rotatably held by a rotating shaft 53 fixed to the housing 41. The reset spring 52 is arranged on the side opposite to the holding shaft 35 with the reset lever 51 interposed therebetween, and the inner cylinder 26 is constantly urged to the left in the drawing via the reset lever 51, the holding shaft 35, and the slide shaft 34. , The inner cylinder 26 is automatically moved to the key insertion position (see FIG. 7).

The data reading means 42 is fixed to the shaft socket 50 away from the outer cylinder 25 and the inner cylinder 26 so that no voltage is applied through the outer cylinder 25 and the inner cylinder 26. The data reading means 42 is arranged on the slide path of the holding shaft 35 so as to be in communicable contact with the keyhole outer contact member 32 only when the inner cylinder 26 is slid to the pushing position against the reset spring 52. Has been done. Therefore, when the electronic key 1 is not inserted into the keyhole 26a, the data reading means 42 does not communicatively contact the keyhole external contact member 32, and the connection with the electronic key 1 is cut off. When the electronic key 1 is inserted into the keyhole 26a and pressed, it comes into communicable contact with the keyhole external contact member 32 and is connected to the electronic key 1. Therefore, in the present embodiment, the connection control means 30 is configured by the keyhole internal contact member 31, the wiring 33, the keyhole external contact member 32, the slide shaft 34, the holding shaft 35, and the reset spring 52.

As shown in FIG. 7, the unlocking permission means 60 includes a solenoid 43, a slide lever 44, a slide plate 45, a slide spring 46, a link member 47, a cam member 48, and a gear cam 49.

As shown in FIG. 9, the cam member 48 is connected to the slide shaft 34 so as to rotate integrally with the slide shaft 34. Further, the cam member 48 is slidably attached to the slide shaft 34. The cam member 48 is provided with a cross-shaped cam 48a so as to engage with the cross-shaped cam groove 49a formed in the gear cam 49. Therefore, when the cam 48a and the cam groove 49a are engaged, the rotational force of the inner cylinder 26 is transmitted to the gear cam 49 via the slide shaft 34 and the cam member 48.

As shown in FIG. 9, a cam groove 48b is formed in an annular shape on the outer peripheral surface of the cam member 48, and the cam pin 47a of the link member 47 is engaged. The link member 47 is swingably held in the housing 41. Therefore, the cam member 48 slides along the slide shaft 34 due to the swing of the link member 47 to engage the cam 48a with the cam groove 49a or release the engagement state between the cam 48a and the cam groove 49a. Let me do it.

As shown in FIGS. 7 and 9, the link member 47 swings toward the inner cylinder 26 side or the side opposite to the inner cylinder 26 when the slide plate 45 reciprocates linearly in the horizontal direction. The slide plate 45 is constantly urged by the slide spring 46 toward the side opposite to the inner cylinder 26. The slide lever 44 is rotatably held by the rotation shaft 53 at a position opposite to the slide spring 46 with the slide plate 45 interposed therebetween. The slide lever 44 is connected to the plunger 55 of the solenoid 43 via the support shaft 54, and rotates about the support shaft 54 according to the vertical movement of the plunger 55.

When the solenoid 43 is not energized and the plunger 55 is projected, the slide lever 44 is in a posture of being separated from the slide plate 45 (hereinafter, also referred to as “non-pressing posture”). On the other hand, when the solenoid 43 is energized and the plunger 55 is sucked upward, the slide lever 44 comes into contact with the slide plate 45 and presses the slide plate 45 toward the inner cylinder 26 side against the slide spring 46 (a posture (). Hereinafter, it is also referred to as “pressing posture”).

As shown in FIG. 7, the slide plate 45 has an opening 45a through which the link member 47 penetrates. When the slide lever 44 is held in a non-pressing posture and the slide plate 45 is urged to the side opposite to the inner cylinder 26 by the slide spring 46, the link member 47 is connected to the inner cylinder 26 by the edge of the opening 45a. It is pressed to the opposite side and swings. In this case, the link member 47 pulls the cam member 48 away from the gear cam 49 and does not engage the cam 48a with the cam groove 48b. In this case, even if the inner cylinder 26 is rotated, the cam member 48 idles and no rotational force is applied to the gear cam 49.

On the other hand, when the slide lever 44 is held in the pressing posture and the slide plate 45 slides toward the inner cylinder 26 side against the slide spring 46, the link member 47 is the pressurizing portion 45c of the slide plate 45. Is pressed against and swings toward the inner cylinder 26 side. As a result, the link member 47 pulls the cam member 48 toward the gear cam 49 and engages the cam 48a with the cam groove 48b. In this case, when the inner cylinder 26 is rotated, the rotational force is transmitted to the slide shaft 34, the cam member 48, and the gear cam 49, and the locking or unlocking can be performed.

By the way, the electric lock 20 includes a hold lever 56 that is rotatably held by the rotating shaft 53. The hold lever 56 is arranged above the holding protrusion 45b of the slide plate 45. The hold spring 57 urges the hold lever 56 toward the slide plate 45 side. The hold lever 56 is provided with a recess 56a that can be engaged with the holding protrusion 45b of the slide plate 45.

The hold lever 56 is restricted in rotation by the reset lever 51 while the reset lever 51 is not pressed against the reset spring 52. When the reset lever 51 is pressed against the reset spring 52, the hold lever 56 is released from the rotation restriction by the reset lever 51. Even if the rotation restriction by the reset lever 51 is released, the hold lever 56 cannot be rotated by being pushed up by the holding protrusion 45b until the holding protrusion 45b comes below the recess 56a. On the other hand, when the slide plate 45 moves so as to arrange the holding protrusion 45b below the recess 56a, the hold lever 56 rotates to engage the recess 56a with the holding protrusion 45b. Since the hold lever 56 is urged by the hold spring 57, it is possible to continue holding the slide plate 45 even when the energization of the solenoid 43 is stopped.

The second unit 22 is covered with a main body cover 40 so that the internal structure cannot be seen from the outside. In the thumb turn 24, the rotating shaft 24a is inserted through the main body cover 40. The tip of the rotating shaft 24a is engaged with a gear 58 rotatably held by the housing 41. The gear 58 meshes with the gear cam 49. Therefore, when the thumb turn 24 is rotated, the gear cam 49 is rotated via the gear 58 to lock or unlock.

Subsequently, the mounting structure of the electric lock 20 will be described.
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.

In the present embodiment, the control board 70 is driven by using the dry battery provided in the electric lock 20 as a power source. Therefore, the electric lock 20 can be installed on the door D without wiring.

Next, the electrical configuration of the electric lock 20 will be described with reference to FIG.
In the electric lock 20, the solenoid 43 and the data reading means 42 are connected to the control board 70. Further, the control board 70 includes a CPU 701, a ROM 702, a RAM 703, and an NVRAM 704.

The ROM 702 stores an unlocking permission program 702a that permits unlocking of the electric lock 20 when the electronic key 1 is authenticated. The NVRAM 704 has a room number information storage unit 704a, a control number storage unit 704b, and a history storage unit 704c. The room number information storage unit 704a stores the room number information to which the electric lock 20 is attached. Further, the control number storage unit 704b stores the control number stored in the control number storage means 10 of the electronic key 1 read by the data reading means 42. The CPU 701 controls the operation of the electric lock 20 while storing the data in the NVRAM 704 according to the program stored in the ROM 702.

Next, the operation procedure of the electric lock 20 will be described with reference to FIG.
When the trader inserts the electronic key 1 into the electric lock 20, the data reading means 42 reads the room number information stored in the electronic key 1, and the CPU 701 uses the read room number information as the room number information of the NVRAM 704. The authority is authenticated by collating with the room number information stored in the storage unit 704a (S11). If the read room number information does not match the room number information stored in the room number information storage unit 704a and the authentication fails (S12: NO), there is a possibility of a reading error or the like. After notifying the error (S19), the process ends. The error notification may be performed by a buzzer, voice, etc., may be displayed by a lamp, etc., 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 42 reads the valid time data stored in the valid time data storage means 11 of the electronic key 1, and the CPU 701 is within the valid time. If it is determined (S13: YES), then the data reading means 42 reads the control number stored in the control number storage means 10 of the electronic key 1. The CPU 701 collates the read control number with the control number stored in the control number storage unit 704b of the NVRAM 704 (S14). When the read control number matches the control number stored in the control number storage unit 704b (S15: same number), the unlock permission program 702a grants unlock permission, and the key cylinder 23 becomes rotatable (S16). .. When the read control number is larger than the control number stored in the control number storage unit 704b (S15: larger number), the control number stored in the control number storage unit 704b is larger than the read control number. After being rewritten to the one number (S18), unlocking permission is given by the unlocking permission program 702a, and the key cylinder 23 becomes rotatable (S16). If the read control number is smaller than the control number stored in the control number storage unit 704b (S15: NO), the CPU 701 gives an error notification (S19) and then ends the process.

As will be described later, each time the electronic key 1 is provided, the key management box 80 sets a number larger than the management number set at the time of the previous provision. Therefore, for example, when the contractor intends to enter the room R for which the contractor has agreed to enter the room, the electric lock 20 has the management number assigned to the electronic key 1 used by the contractor who visited the room R last time (hereinafter, the previous time). The control number) is stored, but the trader's electronic key 1 is given a higher control number (hereinafter referred to as the provision control number) than the control number given to the trader's electronic key 1 that visited the room R last time. Therefore, when the trader inserts the electronic key 1 into the electric lock 20, the previous management number stored in the electric lock 20 is rewritten to the provided management number (S18), and unlocking permission is given (S16). Therefore, even if the trader who visited the room R last time illegally brought back the electronic key 1, even if the electronic key 1 having the control number last time was inserted into the electric lock 20, the authentication was not performed and the lock could not be unlocked (S15: NO).

When the electronic key 1 is used multiple times while the contractor is working, the electric lock 20 stores the provision management number from the second time onward, so that the electronic key 1 is collated with the provision management number of the user's electronic key 1. (S15: same number), unlocking permission is given (S16). After the unlocking permission is given, the CPU 701 stores the lock / unlock history of the door D in the history storage unit 704c of the NVRAM 314 (S17), and ends the process.

<Electronic key management system>
A system for managing the electronic key 1 will be described.
FIG. 12 shows a configuration diagram of the key management box 80. The key management box 80 is provided with an opening / closing door 81, and the opening / closing door 81 is closed in the standby state.

A touch panel 83 as an operating means is attached to the right surface of the opening / closing door 81 of the key management box 80, and a CCD camera 84 and a microphone 88 are attached to the upper surface of the opening / closing door 81. The key hole unit 82 has a key hole 85, an LED 86, and a name plate 87 to which the electronic key 1 is mounted. The key hole 85 is normally in a state in which the electronic key 1 cannot be removed by the key locking means 89 (see FIG. 13) which is a key removal preventing means.

Next, the controller 95 (control means) of the key management box 80 will be described. FIG. 13 shows a block diagram of the control configuration. The controller 95 includes a CPU 96, a ROM 97, and a RAM 98. The ROM 97 includes an electronic key providing program 971 (S21 to S32 in FIG. 14), an electronic key returning program 972 (S41 to S52 in FIG. 15), an electronic key ID storage unit 973, a control number setting unit 974, and an effective time. A data setting unit 975 is provided.

Further, the RAM 98 is between the photographing data storage unit 981 that stores the face information and voice of the trader, the photographing device data storage unit 982 that stores the photographing data photographed by the photographing device 100 described later, and the student dormitory manager in advance. Contracted to deal with troubles in the student dormitory, and allowed entry to the room R with the external user memory unit 983, which remembers multiple vendors who are allowed to enter the room R of the student dormitory. Of the plurality of vendors, the licensed user storage unit 984 that stores the vendor selected in advance by the resident of each room R to receive the service, and the history storage means 12 of the electronic key 1 store the services. It is provided with a history storage unit 985 that stores the usage history of the electronic key 1.

When the key locking means 89A to 89J, which are key removal preventing means attached to the controller 95 corresponding to each key hole unit 82, and the electronic key 1 are attached, the IC tag built in the electronic key 1 is attached. IC tag data reading means 90A to 90J for reading the data stored in 5, and a room for writing the room number information of the room R for which the contractor has agreed to enter the room to the room number information storage means 9 of the electronic key 1. Number information writing means 91A to 91J, control number writing means 92A to 92J for writing the control number in the control number storage means 10 of the electronic key 1, valid time data of unlocking authority is stored in the valid time data storage means 11 of the electronic key 1. Effective time data writing means 99A to 99J and LEDs 86A to 86J for writing to the data are connected. Further, a touch panel 83, a QR code (registered trademark) reading unit 93, a face information acquisition unit 94, a microphone 88, and a communication means 110 are connected to the controller 95. The QR code reading unit 63 and the face recognition unit 64 are connected to the CCD camera 84, and the communication means 110 is a photographing device 100 installed in each room R of the student dormitory and a server 111 of the student dormitory manager. And are connected to.

As shown in FIG. 18, the photographing device 100 is installed on the ceiling of the resident's room R. By installing the photographing device 100 in the room R, it is possible to photograph a state in which the contractor enters the resident's room R and is working with the photographing device 100. The photographing device 100 has a swing function, and is capable of sufficiently photographing the entire room R. Further, the photographing device 100 has a motion detection function, and can detect the entry of a trader and follow the action. Since the photographer has a feeling that it is difficult to cheat in the room R where he / she entered the room, he / she can prevent criminal acts.

Next, the operation of the present embodiment will be described with reference to the flowcharts of FIGS. 14 and 15 and the display images of FIGS. 16 and 17.
First, a case where a contractor enters the room R of the student dormitory will be described.
The contractor is a contractor who has a contract with the student dormitory manager in advance, such as dealing with troubles in the student dormitory, and the resident will receive the services of the contractor contracted with the student dormitory manager. It is a prerequisite that you agree. Then, when the resident actually wants to receive the service, the contractor uses a personal computer, a smartphone, a general telephone, etc. to enter the room R in advance with the student dormitory manager and the resident when the resident is absent. After making an agreement to enter the room, you will receive a QR code from the student dormitory manager that stores information about the agreement, such as the contractor's name, date and time of visit, room number to visit, and scheduled working hours in the dormitory. Up to this point, the key management box 80 is not used. In the standby state of the key management box 80, the display image 831 is displayed on the touch panel 83 as shown in FIG. 16A, and the trader goes to the key management box 80 when entering the student dormitory and the display image. Among the options displayed in 831, "Provide key" 831a is selected. Then, as shown in FIG. 17B, the display image 832 is displayed on the touch panel 83, and the vendor causes the CCD camera 84 to read the QR code stored in the smartphone in advance so as to fit in the display frame 832a (S21). ). The CPU 96 connects to the student dormitory manager's server 111 (see FIG. 13) by the communication means 110, and collates the contents of the agreement.

Here, the collation of the contents of the agreement is based on the information stored in the QR code, whether or not the trader is a trader stored in the external user storage unit 983 and the authorized user storage unit 984, and whether or not the contractor is a resident. The CPU 96 determines whether or not the date and time for entering the room R is the same as the agreement made in advance by the electronic key providing program 971 at the time of entering the room. By determining whether or not the contractor is stored in the external user storage unit 983 and the licensed user storage unit 984, it is possible to prevent the resident from entering the room R other than the contractor. You can get a sense of security.

When the agreement is confirmed (S22: YES), the display image 833 is then displayed on the touch panel 83 as shown in FIG. 16 (c). Here, since the CCD camera 84 takes a picture of the trader and the microphone 88 acquires the voice of the trader, the trader goes to the CCD camera 84 and the microphone 88 and describes the trader name, name, purpose of visit, working time, and the like ( S23). The shooting data acquired by the CCD camera 84 and the microphone 88 is stored in the shooting data storage unit 981 (S24). By memorizing the face information and voice of the trader, the trader feels that it is difficult to cheat in the room R where he / she entered, so that criminal acts can be prevented. The photograph of the trader may be a still image or a moving image.

After that, the room number information writing means 91 writes the room number information (unlocking authority) of the room R for which the contractor has agreed to enter the room to the room number information storage means 9 of the arbitrary electronic key 1 (S25). Further, the control number writing means 92 writes the control number in the control number storage means 10 of the electronic key 1, and the effective time data writing means 99 writes the effective time data in the effective time data storage means 11 of the electronic key 1. Write (S26).

The management number is managed by the student dormitory administrator's server 111 through the communication means 110, and is the electronic key 1 used for the same room number, and is from the management number assigned to the electronic key 1 provided earlier. A control number having a large number is set by the control number setting unit 974. Then, the control number of the large number is written in the control number storage means 10 of the electronic key 1 by the control number writing means 92 (for example, the electronic key 1 of the contractor who visited the room R last time when he / she entered the room 101). If the control number 10 is assigned, the control number 11 is set and assigned to the electronic key 1 of the trader who enters the room 101 this time). Further, the valid time data is set by the valid time data setting unit 975 based on the information regarding the scheduled working time in the student dormitory stored in the QR code. After the valid time elapses, the electronic key 1 cannot be unlocked even if it is inserted into the electric lock 20 of the room R that has been agreed to enter the room, and loses its function as a key.

Next, the controller 95 opens the opening / closing door 81, and at the same time, displays a display image 834 on the touch panel 83 as shown in FIG. 16D, and a key to which an arbitrary electronic key 1 into which data is written is attached. The key locking means 89 of the hole unit 82 is released, and the LED 86 of the released key hole unit 82 is turned on (S27). Therefore, the trader can take out the predetermined electronic key 1. When the electronic key 1 is extracted and the IC tag data reading means 90 does not detect the electronic key 1, the controller 95 determines that the electronic key 1 has been extracted from the key hole 85 (S28: YES) and is extracted. The electronic key 1 and the time taken out are stored in the history storage unit 985 (S29).

Since the time when the trader took out the electronic key 1 is stored and the time when the electronic key 1 is returned in S48 of FIG. 15 is stored in the history storage unit 985 as described later, the staying time in the student dormitory of the trader is stored. It can be confirmed. Therefore, since it is possible to confirm whether or not the staying time is commensurate with the purpose of the visit of the contractor, the contractor feels that it is difficult to cheat in the room R where he / she entered, and it is possible to prevent criminal acts and actually cheat. It can be circumstantial evidence if done.

After the time when the electronic key 1 is taken out is stored in the history storage unit 985, the display image 835 is displayed on the touch panel 83 as shown in FIG. 16E, and the user is instructed to close the opening / closing door 81. (S30). When it is confirmed that the opening / closing door 81 is closed (S31: YES), the key management box 80 contains the photographed data of the vendor stored in the photographed data storage unit 981 in S24 and the electronic key stored in the history storage unit 985 in S29. The take-out time of 1 is transmitted to the resident's smartphone 120 or the like by the communication means 110 (S32).

As shown in FIG. 18, the resident can confirm the shooting data by playing back the shooting data on the screen 120a of the smartphone 120. At this time, the voice spoken by the trader, such as the trader's name, name, purpose of visit, and working hours, is also reproduced. Residents can know that the contractor has visited and what kind of person has visited, which gives them a sense of security. In particular, when the resident is a woman and wishes to visit a female worker, etc., the resident can know that the female worker is definitely visiting by checking the face information. You can get a sense of security.

When the transmission of the photographed data of the trader and the extraction time of the electronic key 1 is completed, the electronic key providing program 971 at the time of entering the room is terminated, and the display image 831 is displayed on the touch panel 83 as shown in FIG. 16A.

By receiving the electronic key 1 provided by the electronic key provision program 971 when entering the room, the contractor can deal with troubles in the student dormitory and deliver the luggage even when the resident is absent. Efficient because there is no need to readjust the work schedule or redeliver the package.

The key management box 80 may provide not only the electric lock 20 of a specific room R but also the electronic key 1 capable of unlocking the electric lock 20 of two or more rooms R of all the rooms R of the student dormitory. It is possible. For example, if the contractor has agreed with multiple residents on the same day to work while the resident is absent, the contractor will ask the student dormitory manager in advance about the contractor's name, date and time of visit, and visit. Receive a QR code that stores information about the agreement, such as the room number to be used and the scheduled working hours in the dormitory. When cleaning, the cleaning staff goes to the key management box 80 and has the CCD camera 84 of the key management box 80 read the QR code. The CPU 96 connects to the student dormitory manager's server 111 by the communication means 110 and collates the agreement information. When the agreement is confirmed, if there are a plurality of rooms R visited by the contractor in the room number information storage means 9 of any electronic key 1 by the room number information writing means 91, all the room number information (unlocking authority). ) Is written. If there are multiple rooms R visited by the trader, it is a roundabout way to go to the key management box 80 and receive the electronic key 1 every time the work of one room R is completed, so one electronic key. It is practical to be able to unlock the electric lock 20 of the room R visited in 1.

Next, the operation of the photographing apparatus 100 when the trader enters the room R will be described with reference to FIGS. 18 to 20.
When the trader unlocks the electric lock 20 with the electronic key 1 taken out from the key management box 80 and enters the room R, the photographing device 100 installed in the room R has a motion detection function, so that the trader enters the room. Detected (S61: YES) and started shooting in the room R (S62). Since the photographing device 100 has a swing function, it is possible to take a picture while chasing the behavior of the trader by the motion detecting function. Since the photographer has a feeling that it is difficult to cheat in the room R where he / she entered the room, he / she can prevent criminal acts.

The photographing device 100 notifies the student dormitory manager's server 111 and the resident's smartphone 120 that the photographing has started via the communication means 110 (S63). After that, in order to transmit the state in the room R (photographing device data) photographed by the photographing device 100 in real time via the communication means 110 (S64), the student dormitory manager and the resident who received the notification in S63 are in the room. It is possible to confirm in real time how the contractor works in R. In addition, in S63, not only the server 111 of the student dormitory manager and the smartphone 120 of the resident, but also the management department of the contractor can be notified that shooting has started, and in S64, the shooting device data can be notified to the management department. Can also be transmitted in real time.

As long as the motion detection function continues to detect the movement of the vendor, the shooting and the real-time transmission of the shooting device data can be continued (S65: YES). Then, when the contractor leaves the room and the motion detection function does not detect the movement of the contractor (S65: NO), the photographing device 100 ends the photographing (S66).

The photographing device data is transmitted to the key management box 80 via the communication means 110 and stored in the photographing device data storage unit 982. The stored imaging device data can be transmitted to the student dormitory manager's server 111 and the resident's smartphone 120 via the communication means 110. In addition, it is possible to transmit the photographing device data not only to the server 111 of the student dormitory manager and the smartphone 120 of the resident, but also to the management department of the contractor.

Student dormitory managers and residents can check the state of work in room R by checking the imaging device data. For example, if the resident requests home delivery, the courier does not take any action other than bringing the luggage to room R, or if the resident asks the contractor to replace the lamp, the contractor is in room R. Since you can check if you have moved to a place that is not related to the lamp replacement work, you can know whether the contractor is cheating in the resident's room R, and you can feel secure. be able to. Furthermore, if the shooting data is sent to the management department of the contractor, it is possible to check whether the person in charge of the work is cheating at the visited place.

Next, a case where the trader returns the electronic key 1 to the key management box 80 will be described.
The trader goes to the key management box 80 and selects "return key" 831b from the options displayed in the display image 831 (FIG. 16A). In this case, as shown in FIG. 17A, the display image 842 is displayed on the touch panel 83, and the vendor reads the QR code previously stored in the smartphone by the CCD camera 84 so as to fit in the display frame 842a. Let (S41). The CPU 96 connects to the student dormitory manager's server 111 (see FIG. 13) by the communication means 110, and collates the agreement content information.

When the agreement is confirmed (S42: YES), the display image 843 is displayed on the touch panel 83 as shown in FIG. 17 (b). Here, since the CCD camera 84 takes a picture of the trader and the microphone 88 acquires the voice of the trader, the trader heads for the CCD camera 84 and the microphone 88, and the trader name, name, purpose of visit, work time, and scheduled work. If the work cannot be performed on time, the reason and the like will be described (S43). The shooting data acquired by the CCD camera 84 and the microphone 88 is stored in the shooting data storage unit 981 (S44). By memorizing the face information and voice of the trader, the trader feels that it is difficult to cheat in the room R where he / she entered, so that criminal acts can be prevented. The photograph of the trader may be a still image or a moving image.

Next, the controller 95 opens the opening / closing door 81, and at the same time, releases the key locking means 89 of the key hole unit 82 to which the electronic key 1 is not mounted (S45). As shown in FIG. 17C, the display image 844 is displayed on the touch panel 83, and the trader returns the electronic key 1 to an arbitrary key hole 85 to which the electronic key 1 is not mounted (S46). When the electronic key 1 is returned to the key management box 80, the IC tag data reading means 90 reads the electronic key ID of the electronic key 1 and confirms that the electronic key 1 borrowed by the trader has been returned ( S47: YES), the return time is stored in the history storage unit 985 (S48).

Since the time when the trader took out the electronic key 1 is stored in S29 of FIG. 14, the time when the trader returned the electronic key 1 in S48 is stored in the history storage unit 985, so that the time spent in the student dormitory of the trader is stored. Can be confirmed. Therefore, since it is possible to confirm whether or not the staying time is suitable for the purpose of the visit of the contractor, the contractor feels that it is difficult to cheat in the room R where he / she entered the room, and it is possible to prevent criminal acts and actually cheat. It can be circumstantial evidence if done.

After the return time is stored in the history storage unit 985, the usage history data read from the electronic key 1 by the IC tag data reading means 90 of the controller 95 is stored in the history storage unit 985 as the usage history of the electronic key 1. (S49). After that, as shown in FIG. 17D, the display image 845 is displayed on the touch panel 83, and the contractor is instructed to close the opening / closing door 81 (S50). After that, as shown in FIG. 17D, the display image 845 is displayed on the touch panel 83, and the contractor is instructed to close the opening / closing door 81 (S50). When it is confirmed that the opening / closing door 81 is closed (S51: YES), the key management box 80 contains the photographed data of the vendor stored in the photographed data storage unit 981 in S44 and the electronic key stored in the history storage unit 985 in S48. The return time of 1 is transmitted to the resident's smartphone or the like by the communication means 110 (S52).

As shown in FIG. 20, the resident can confirm the shooting data by playing back the shooting data on the screen 120a of the smartphone 120. At this time, the voice spoken by the trader, such as the trader's name, name, purpose of visit, working time, and the reason why the work could not be performed according to the scheduled working time, is also reproduced. Residents can be reassured that they have completed the handling of problems in the student dormitory and that the contractor has definitely left Room R. In addition, by knowing that the contractor has left the room R, the resident can return home in the room R without having to collaborate with the contractor.

When the transmission of the photographed data of the trader and the return time of the electronic key 1 is completed, the electronic key return program 972 ends, and the display image 831 is displayed on the touch panel 83 as shown in FIG. 16A.

If the electronic key 1 is not returned to the key management box 80 even after the valid time determined by the valid time data stored in the electronic key 1 has elapsed, the key management box 80 is used by the student dormitory manager through the communication means 110. It is possible to communicate with the server 72 and issue a warning to the dormitory manager and the contractor.

As described above, according to the key management box 80 of the present embodiment,
