[0009] Below, we will explain Examples 1 and 2, in which the present disclosure is embodied in a key lending system 1 for lending keys to users U, with reference to the drawings. In the following explanation, "manager" includes the manager of an apartment building and / or a resident of dwelling unit R. Furthermore, "user U" includes a person who temporarily uses dwelling unit R with key K for dwelling unit R. In each example, common components are given the same reference numerals and will not be explained further. [Example]

[0010] In the first embodiment, the key lending system 1 is installed in a common entrance terminal 102.

[0011] As shown in FIG. 1(a), a user U can receive a key K from a key box 2 by having a camera 121 read a two-dimensional barcode Qu distributed in advance by the manager of the dwelling unit R. As shown in FIG. 1(b), when the user U puts the key K into the key box 2, a camera 2a photographs the key K. The collective entrance device 102 then verifies the key K based on the image from the camera 2a.

[0012] As shown in Fig. 2, the apartment building intercom system 101 includes an apartment entrance unit 102 installed in a common area of ​​an apartment building including multiple dwelling units R, an entrance sub-unit 103 and a room main unit 104 installed in each dwelling unit R, and a controller 105 that controls the apartment building intercom system 101. Each dwelling unit R can also be used for private lodging, etc.

[0013] The collective entrance device 102 includes a key box 2 that stores keys K, a CPU 126 (Central Processing Unit), and a storage unit 127. The number of key boxes 2 provided in the collective entrance device 102 can be changed as appropriate.

[0014] The collective entrance device 102 also includes a camera 121 that captures images of the area around the collective entrance device 102, a microphone 122, a speaker 123, a display unit 124 for displaying images and text, and an operation unit 125 that includes room number keys and a call button. The display unit 124 and the operation unit 125 can also be touch panels. The camera 121 can also read two-dimensional barcodes.

[0015] The operation unit 125 includes a key box unlock button (not shown) for unlocking the key box 2 and a key box lock button (not shown) for locking the key box 2.

[0016] The speaker 123 functions as the output unit 4 that outputs the matching result by the key matching unit 33 to the user U by voice. The display unit 124 functions as the output unit 4 that outputs the matching result by the key matching unit 33 to the user U by image. For example, the output unit 4 outputs a message indicating key matching failure (such as "The key is incorrect") when matching by the key matching unit 33 fails, and outputs a message indicating return completion (such as "Key return completed") when matching by the key matching unit 33 is successful. Note that the output unit 4 can also output a message indicating user authentication failure (such as "User U could not be authenticated") when user authentication by the user authentication unit 34 fails.

[0017] The key box 2 is equipped with a camera 2a that photographs the inside of the key box 2, and an electronic lock 2b. The camera 2a photographs the inside of the key box 2 when the user U presses the key box lock button. Alternatively, the camera 2a may be configured to photograph the inside of the key box 2 when the user U closes the door of the key box 2. The camera 2a can also read two-dimensional barcodes.

[0018] The storage unit 127 is composed of a ROM (Read Only Memory) and a RAM (Random Access Memory). The ROM is a non-volatile memory or the like, and stores various programs, files used by the programs, parameters, etc. The RAM temporarily stores data used when the various programs are executed.

[0019] The common entrance device 102 includes a key matching unit 33 that matches the key K returned to the key box 2 based on the image from the camera 121, a locking / unlocking unit 32 that locks and unlocks the electronic lock 2b of the key box 2, a notification unit 31 that notifies the manager of the dwelling unit R of the matching result by the key matching unit 33, and a user authentication unit 34 that authenticates the user U who lends the key K. The key matching unit 33, the locking / unlocking unit 32, the notification unit 31, and the user authentication unit 34 can each be installed as a program in the ROM of the memory unit 127. The CPU 126, the memory unit 127, the key matching unit 33, the locking / unlocking unit 32, the notification unit 31, and the user authentication unit 34 function as a control unit 3 that controls the key lending system 1.

[0020] The user authentication unit 34 authenticates the user U based on the image captured by the camera 121. For example, the camera 121 reads a two-dimensional barcode Qu, and authenticates the user U based on the user authentication information contained in the two-dimensional barcode Qu. The user authentication information includes a password, etc. The user authentication information is registered in advance in the storage unit 127 by the administrator of the dwelling unit R, and is distributed to the user U together with the two-dimensional barcode Qu. Note that the administrator may also register biometric information such as a facial image and fingerprints of the user U in the storage unit 127 in advance, and the user authentication unit 34 may authenticate the user U by comparing the biometric information with the user U contained in the image captured by the camera 121.

[0021] The key matching unit 33 matches the key K based on the image captured by the camera 2a. For example, the camera 2a reads the two-dimensional barcode Qk, and matches the key K based on the key identification information included in the two-dimensional barcode Qk. The key identification information is registered in advance in the storage unit 127 by the manager of the dwelling unit R, and is included in the two-dimensional barcode Qk and printed on the tag of the key K. Alternatively, the manager may register an image of the key K in the storage unit 127 in advance, and the key matching unit 33 may match the image of the key K with the key K included in the image captured by the camera 2a.

[0022] The notification unit 31 notifies the manager of the dwelling unit R of the result of the matching by the key matching unit 33. For example, if the matching by the key matching unit 33 fails, the notification unit 31 notifies the manager of a key matching failure message (such as "The key returned by user U is incorrect"), and if the matching by the key matching unit 33 is successful, the notification unit 31 notifies the manager of a return completion message (such as "The key has been returned"). The notification unit 31 can also notify the manager of a rental completion message (such as "The key rental has been completed"). The notification unit 31 is provided with a SIM (Subscriber Identity Module) and is configured to be able to call a mobile terminal carried by the manager.

[0023] The locking / unlocking unit 32 unlocks the electronic lock 2b when the user authentication unit 34 is successful when lending out the key K or when returning the key K. The locking / unlocking unit 32 also locks the electronic lock 2b when the key matching unit 33 is successful when returning the key K.

[0024] The control device 105 includes a CPU 156 and a memory unit 157. The memory unit 157 is composed of a ROM and a RAM. The ROM is a non-volatile memory or the like, and stores various programs, as well as files and parameters used by the programs. The RAM temporarily stores data used when various programs are executed. The control device 105 can also be provided with a key matching unit 33, a locking / unlocking unit 32, a notification unit 31, and a user authentication unit 34, and can serve as a control unit 3 that controls the key lending system 1.

[0025] Next, the flow of lending the key K to the user U using the collective entrance device 102 configured as described above will be described with reference to FIG.

[0026] 3, when the user U operates the key box unlock button, the CPU 126 activates the camera 121 and reads the two-dimensional barcode Qu (S1). The user authentication unit 34 authenticates the user U based on the user authentication information in the two-dimensional barcode Qu and the user authentication information read from the storage unit 127 (S2). If the authentication of the user U fails (S3: No), a message indicating that the user authentication has failed is output to the output unit, and the process ends.

[0027] On the other hand, if the authentication of user U is successful (S3: Yes), the locking / unlocking unit 32 unlocks the electronic lock 2b (S4). When user U removes key K from key box 2, closes key box 2, and operates the key box lock button, the locking / unlocking unit 32 locks electronic lock 2b (S5). The notification unit 31 notifies the manager with a message that the lending is complete (S6).

[0028] Next, the flow of the user U returning the key K using the collective entrance device 102 will be described with reference to FIG.

[0029] The flow of S1 to S4 in Fig. 4 is the same as S1 to S4 in Fig. 3, and therefore description thereof will be omitted. When user U places key K in key box 2 and operates the key box lock button (S5), CPU 126 activates camera 2a, which reads two-dimensional barcode Qk printed on the tag of key K (S6). Key verification unit 33 verifies key K based on the key identification information in two-dimensional barcode Qk and the key identification information read from storage unit 127 (S7). If verification of key K fails (S8: No), notification unit 31 notifies the administrator of a key verification failure message (S10). In addition, a message of key verification failure is output to the output unit.

[0030] On the other hand, if the key matching unit 33 matches successfully (S8: Yes), the locking / unlocking unit 32 locks the electronic lock 2b. The notification unit 31 notifies the administrator of the completion of the return with a message (S9). The output unit also outputs a message of the completion of the return.

[0031] According to the collective entrance device 102 (key lending system 1) configured as described above, a camera 2a is provided to capture images of the inside of the key box 2, and the key K returned to the key box 2 is verified based on the image captured by the camera 2a, making it possible to confirm that the correct key K has been returned. Furthermore, because the key box 2 is provided integrally with the collective entrance device 102, it is possible to save space compared to arranging the key box 2 and the collective entrance device 102 separately, and it is possible to create a unified appearance and improve the design. [Example]

[0032] In the second embodiment, the key lending system 1 is installed in an intercom system 201 for individual residences.

[0033] As shown in FIG. 5(a), the user U can receive the key K from the key box 2 by having the camera 231 read the two-dimensional barcode Qu distributed in advance by the manager of the dwelling unit R. As shown in FIG. 5(b), when the user U puts the key K into the key box 2, the camera 2a photographs the key K. Thereafter, the key verification unit 33 of the room master unit 204 verifies the key K based on the image captured by the camera 2a.

[0034] As shown in Fig. 6, the individual residence intercom system 201 includes an entrance slave unit 203 and a room master unit 204. The dwelling unit R can also be used for private lodgings.
