[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-127196 Summary of the Invention [Problem to be solved by the invention]

[0004] Suppose a configuration is adopted in which the items to be stored by the storage unit or the holding unit that holds those items can only be managed by an authorized person identified by an identification unit. In that case, even if the items or holding units to be stored by the storage unit are managed, they cannot be managed unless an operation is performed to be identified as an authorized person by the identification unit. In other words, the operability of managing the items or holding units to be stored by the storage unit is poor. For example, there are cases where the operability of the storage unit when storing the object to be stored or the holding unit in the storage unit is poor. Furthermore, there are cases where operability is poor when managing items or holders that are or are not to be stored by a storage unit using their identification information. Furthermore, there are cases where the operability is poor when storing an item or holding part reserved for storage in a storage part in the storage part.

[0005] An object of the present invention is to improve operability when managing items to be stored in a storage unit or a holding unit. An object of the first aspect of the present invention is to improve operability when storing an article to be stored by a storage section or a holding section in the storage section. An object of the second aspect of the present invention is to improve operability when managing items or holders that are to be stored or not to be stored by a storage unit using their identification information. An object of the third aspect of the present invention is to improve operability when storing an article or a holding part that has been reserved for storage in a storage part in the storage part. [Means for solving the problem]

[0006] With this objective in mind, the present invention provides an item management system comprising: a storage unit that stores items or holding units that hold items; a reading unit that reads identification information attached to the items or holding units; and a control unit that performs control to manage the items or holding units to be stored by the storage unit based on the identification information read by the reading unit.

[0007] A first aspect of the present invention provides an item management system that includes a door that can be locked to restrict operations of storing items or holding units in a storage unit, and a control unit that controls the door to be unlocked when the identification information read by the reading unit is the identification information of the item or holding unit to be stored by the storage unit.

[0008] The control unit may control the door not to be unlocked if the identification information read by the reading unit is not the identification information of the item or holding unit to be stored by the storage unit. In this case, the item management system may further include an output unit that outputs information to the outside, and the control unit may control the output unit to output information to that effect if the identification information read by the reading unit is not the identification information of the item or holding unit to be stored by the storage unit. If the identification information read by the reading unit is not the identification information of the item to be stored by the storage unit or the holding unit, the control unit may record information to that effect and control the door to be unlocked.

[0009] A second aspect of the present invention provides an article management system in which the control unit manages the identification information read by the reading unit as identification information of the article to be stored by the storage unit or the holder.

[0010] The control unit may manage the identification information read by the reading unit as identification information of the item or holding unit to be stored by the storage unit by registering information that corresponds the identification information read by the reading unit with item information regarding the item or holding unit to which the identification information is attached.

[0011] A second aspect of the present invention also provides an article management system in which the control unit manages the identification information read by the reading unit as identification information of an article not to be stored by the storage unit or of a holder.

[0012] The control unit may manage the identification information read by the reading unit as identification information of an item or holding unit that is not to be stored by the storage unit by deleting information that associates the identification information read by the reading unit with item information regarding the item or holding unit to which the identification information is attached. The item management system may further include an output unit that outputs item information regarding the items or holding units that are to be stored by the storage unit, and the control unit may control the output unit to output information that the identification information has been read, in association with the item information regarding the items or holding units that have the identification information read by the reading unit.

[0013] A third aspect of the present invention provides an item management system that includes a door that can be locked to restrict operations of storing items or holding units in a storage unit, and a control unit that controls the door to be unlocked when the identification information read by the reading unit is the identification information of an item or holding unit that has been scheduled for storage by the storage unit.

[0014] The item management system may further include a second storage unit that stores the item or holding unit, and the second storage unit may output identification information of the item or holding unit in response to the item or holding unit being removed, and the control unit may identify the identification information output by the second storage unit as identification information of the item or holding unit that is scheduled to be stored by the storage unit. In this case, the item management system may further include a transfer unit connected to the second storage unit and the control unit via a communication line, and the second storage unit may transmit identification information of the item or holding unit to the transfer unit, and the transfer unit may receive the identification information of the item or holding unit from the second storage unit and transmit the identification information of the item or holding unit to the control unit. The item management system may further include a reception unit that receives the type of item or holding unit, and the second storage unit notifies the location where the item or holding unit of the type received by the reception unit should be stored. In this case, the item management system may further include a transfer unit connected to the reception unit and the second storage unit via a communication line, and the reception unit may transmit the type of item or holding unit to the transfer unit, and the transfer unit may receive the type of item or holding unit from the reception unit and transmit information for identifying the location where the item or holding unit of the type should be stored to the second storage unit.

[0015] The present invention also provides an item management method in an item management system having a storage unit that stores items or holding units that hold items, the method including the steps of: a reading unit reading identification information attached to the item or holding unit; and a control unit performing control to manage the items or holding units to be stored by the storage unit based on the identification information read by the reading unit.

[0016] Furthermore, the present invention also provides a program that causes an item management system having a storage unit that stores items or holding units that hold items to function as a reading unit that reads identification information attached to the items or holding units, and a control unit that performs control to manage the items or holding units to be stored by the storage unit based on the identification information read by the reading unit. [Effects of the Invention]

[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0020] [Overall configuration of key management system] 1 is a diagram showing an example of the overall configuration of a key management system 1 according to this embodiment. The key management system 1 may manage any keys. However, the following description will be given taking as an example a case where keys for construction machinery in a construction machinery rental service are managed.

[0021] As shown in the figure, the key management system 1 includes a first key management device 10a and a second key management device 10b. The key management system 1 further includes a management client 40 and a management server 50. The key management system 1 further includes a communication line 80 such as the Internet.

[0022] The first key management device 10a is a key management device that enables the keys of construction machines to be rented out, for example, even at night. Therefore, the first key management device 10a is a so-called outdoor key management device installed outdoors in the construction machine rental service office F. The first key management device 10a is operated by an administrator or a user. The administrator is a user who manages the keys, such as a staff member of a company that provides the construction machine rental service. The user is a user who uses the keys, such as a customer who receives the construction machine rental service. The first key management device 10a is connected to the management server 50 via a communication line 80. Note that although only one first key management device 10a is shown in the figure, multiple first key management devices 10a may be installed.

[0023] The second key management device 10b is a key management device that enables centralized management of keys that may be rented out by the first key management device 10a. Therefore, the second key management device 10b is a so-called centralized management board installed in the construction equipment rental service office F. The second key management device 10b is operated by an administrator. However, the second key management device 10b may also handle the lending and returning of keys, just like the first key management device 10a. In that case, the second key management device 10b is also operated by the user. The second key management device 10b is connected to the management server 50 via a communication line 80. Note that although only one second key management device 10b is shown in the figure, multiple second key management devices 10b may be installed.

[0024] The management client 40 is a client computer used to input reservation information. When a user makes a reservation to lend a key, the administrator inputs the reservation information related to the reservation into the management client 40. The reservation information includes information about the user, the key, the lending period, etc. The management client 40 is operated by the administrator, so it is preferable that it be installed in the office F. The management client 40 is connected to the management server 50 via a communication line 80. Therefore, when the reservation information is input, the management client 40 transmits the reservation information to the management server 50. The management client 40 is preferably realized, for example, by a PC (Personal Computer). Note that although only one management client 40 is shown in the figure, multiple management clients 40 may be installed.

[0025] The management server 50 is a server computer that controls the lending of keys. When the management server 50 receives reservation information from the management client 40, it performs processing for lending the key based on the reservation information. For example, the management server 50 issues a code that can be used to instruct the first key management device 10a by holding it over the first key management device 10a. The code may be a one-dimensional or two-dimensional code. Alternatively, the code may be considered as a graphic code. In the following description, a QR code (registered trademark) is used as the code. The management server 50 may be implemented by a general-purpose computer or the like. The management server 50 may also be implemented by the same device as the management client 40.

[0026] This embodiment can also be applied to an item management system that manages items other than keys. However, the following description will be given assuming that this embodiment is applied to the key management system 1.

[0027] [External configuration of the first key management device] Fig. 2 is a diagram showing an example of the external configuration of first key management device 10a in this embodiment. As shown in Fig. 2, first key management device 10a has an outer door 21a on its front surface that can be opened and closed. First key management device 10a also has a key storage unit 23a that can be opened and closed by outer door 21a. First key management device 10a also has a display / operation unit 25a, an RFID (Radio Frequency Identification) reader 26a, and a code reader 27a on its front surface. Furthermore, first key management device 10a has a return box 29a.

[0028] The key storage section 23a is a space for storing keys. The outer door 21a can be locked and unlocked. The outer door 21a is usually locked so that only authorized administrators or users can access the key storage section 23a. The key storage section 23a is an example of a storage section that stores a holding section. The outer door 21a is an example of a door that can be locked to restrict the operation of storing a holding section in the storage section. The key storage section 23a has a plurality of inner doors 22a on its front surface that can be opened and closed. The key storage section 23a is provided with a plurality of (12 in this example) individual storage sections 24a, each of which can be opened and closed by a corresponding inner door 22a. The individual storage sections 24a detachably store holders 31 that hold keys. Note that, although the following description will be given assuming that the inner doors 22a cannot be locked or unlocked, they may be lockable and unlockable.

[0029] Each individual storage section 24a is provided with a locking mechanism 241a to permit or prohibit removal of the holder 31. The first key management device 10a controls the locking mechanism 241a for each individual storage section 24a. In this way, the first key management device 10a controls whether or not removal of each holder 31 is permitted. A light-emitting unit 242a is also provided on the front surface of the inner door 22a corresponding to each individual storage section 24a. The light-emitting unit 242a is, for example, an LED (Light Emitting Diode). Furthermore, an RFID reader 243a is provided in the space within the inner door 22a corresponding to each individual storage section 24a.

[0030] The display operation unit 25a is, for example, a touch panel display, which accepts operations by a user and displays various information. The display operation unit 25a is an example of an output unit that outputs information to the outside. The RFID reader 26a is a reading device that reads RFID information from the holder 31. The RFID information is an example of identification information attached to an item. The RFID reader 26a is an example of a reading unit that reads the identification information. The code reader 27a is a reading device that reads codes from various media. For example, the code reader 27a may be a QR code reader that reads a QR code (registered trademark) displayed on the screen of a terminal device. Alternatively, the code reader 27a may be a QR code reader that reads a QR code printed on paper.

[0031] The return box 29a is a box in which used keys can be returned. Used keys can be returned to the return box 29a so that the multiple individual storage sections 24a can be used to the maximum extent possible for loaned keys. The return box 29a has an inner door 291a on its front that can be opened and closed. The inner door 291a has an insertion slot 292a and a dial lock 293a. After using a key, a user can return the holder 31 that holds the key to the return box 29a through the insertion slot 292a. The administrator can unlock and open the inner door 291a with the dial lock 293a. The administrator can then remove the holder 31 from inside the return box 29a.

[0032] 2 are merely examples, and the first key management device 10a may include other components. For example, the first key management device 10a may include a speaker. In that case, instead of displaying a warning on the display operation unit 25a, an alarm may be output from the speaker. The first key management device 10a may also include a card reader.

[0033] [External configuration of the second key management device] 3 is a diagram showing an example of the external configuration of second key management device 10b in this embodiment. As shown in Fig. 3, second key management device 10b is provided with key storage unit 23b and display operation unit 25b on its front surface.

[0034] The key storage section 23b is a space for storing keys. The key storage section 23b is provided with a plurality of (88 in this example) individual storage sections 24b. The individual storage sections 24b detachably store holders 31 that hold keys.

[0035] Each individual storage unit 24b is provided with a locking mechanism 241b to permit or prohibit removal of the holder 31. The second key management device 10b controls the locking mechanism 241b for each individual storage unit 24b. In this way, the second key management device 10b controls whether or not removal of each holder 31 is permitted. Each individual storage unit 24b is also provided with a light-emitting unit 242b. The light-emitting unit 242b is, for example, an LED. Furthermore, each individual storage unit 24b is provided with an RFID reader 243b.

[0036] The display operation unit 25b is, for example, a touch panel display, which accepts operations by the user and displays various information.

[0037] 3 are merely examples, and the second key management device 10b may include other components. For example, the second key management device 10b may include a speaker. In that case, instead of displaying a warning on the display operation unit 25b, an alarm may be output from the speaker. The second key management device 10b may also include a card reader.

[0038] [Holder and key configuration] 4 is a diagram showing an example of the external configuration of the holder 31 and the key 33 used in this embodiment. As shown in FIG. The holder 31 is provided with an IC tag 34. The IC tag 34 is an RFID tag. The RFID tag has RFID information for identifying the holder 31. To provide the IC tag 34 on the holder 31, for example, a sticker-type IC tag 34 may be attached to the holder 31, or the IC tag 34 may be embedded in the holder 31. The holder 31 is an example of a holding part that holds an item.

[0039] [Outline of this embodiment] In this embodiment, in such a key management system 1, an administrator or a user inserts and removes a key 33 into and from the first key management device 10a. Here, inserting and removing means returning, loading, collecting, etc. At that time, the administrator or the user reads the IC tag 34 attached to the holder 31 connected to the key 33. This reduces the effort required to insert and remove the key 33 in and from the first key management device 10a.

[0040] Specifically, in the first mode, the user reads the IC tag 34 when returning the key 33. This allows the first key management device 10a to check the data, and if the check result is normal, allows the key 33 to be returned. In the second aspect, the administrator reads the IC tag 34 when registering the key 33. The administrator also reads the IC tag 34 when collecting the key 33. This causes the first key management device 10a to check the data, and if the check result is normal, displays the data of the key 33 to be collected. Furthermore, in a third aspect, the administrator removes the key 33 from the second key management device 10b and loads it into the first key management device 10a. At this time, the administrator causes the IC tag 34 to be read. The first key management device 10a then checks the data, and if the check result is normal, registers the data of the key 33.

[0041] [First embodiment] (overview) The first embodiment is an invention relating to an improvement in the control of the return of the holder 31 in the first key management device 10a. Specifically, the user causes the first key management device 10a to read the IC tag 34 of the holder 31 while the outer door 21a is locked. The first key management device 10a then determines whether the holder 31 is a subject of management by the first key management device 10a. If the first key management device 10a determines that the holder 31 is one that is subject to its own management, it unlocks the outer door 21a, allowing the user to return the holder 31 without using an ID card. If the first key management device 10a determines that the holder 31 is not under its management, it does not unlock the outer door 21a and displays a message on the display operation unit 25a indicating that the holder 31 is not under its management.

[0042] The following describes the differences between the return operation in the first key management device 10a before and after the first embodiment is applied.

[0043] First, a case where the holder 31 is returned to the first key management device 10a before the first embodiment is applied will be described. In this case, if the outer door 21a is unlocked, no authentication is required. In other words, the user can return the holder 31 without being authenticated. On the other hand, if the outer door 21a is locked, authentication is required. Here, authentication is authentication that the person is an authorized person. Such authentication is performed by an ID card held by the authorized person. That is, if the user is authenticated as an authorized person, the user can unlock the outer door 21a and return the holder 31. On the other hand, unless the user is authenticated as an authorized person, the user cannot unlock the outer door 21a and cannot return the holder 31.

[0044] Next, a case where the holder 31 is returned to the first key management device 10a after the first embodiment has been applied will be described. In this case, if the outer door 21a is unlocked, no authentication is required. That is, the user can return the holder 31 without being authenticated. This is the same as the first key management device 10a before the first embodiment was applied. On the other hand, if the outer door 21a is locked, authentication is required. Here, authentication includes authentication of the authorized person. Such authentication is performed using an ID card held by the authorized person. Authentication also includes authentication by reading the holder 31. In other words, if the user is authenticated as an authorized user, the user can unlock the outer door 21a and return the holder 31. This is also the same as the first key management device 10a before the first embodiment was applied. On the other hand, suppose the user has not been authenticated as an authorized user. In this case, if the user is authenticated by reading the holder 31, the user can unlock the outer door 21a and return the holder 31. Furthermore, if the user is not authenticated by reading the holder 31, the user cannot unlock the outer door 21a and cannot return the holder 31. This is different from the first key management device 10a before the first embodiment was applied.

[0045] (Functional configuration of the first key management device) 5 is a block diagram showing an example of the functional configuration of a first key management device 10a according to the first embodiment. As shown in the figure, the first key management device 10a includes a control unit 11a, a storage unit 14a, a communication unit 15a, and an outer door locking mechanism 16a. The first key management device 10a further includes a locking mechanism 241a, a light-emitting unit 242a, and an RFID reader 243a. The first key management device 10a further includes a display operation unit 25a, an RFID reader 26a, and a code reader 27a.

[0046] The control unit 11a includes an arithmetic circuit such as a CPU (Central Processing Unit), etc. The control unit 11a controls each unit of the first key management device 10a in accordance with an operation program stored in the storage unit 14a. The storage unit 14a includes a ROM (Read Only Memory), a RAM (Random Access Memory), etc. The storage unit 14a stores the operation programs of the control unit 11a. The storage unit 14a is also used as a work area when the control unit 11a performs control processing. The operation programs include programs for the control unit 11a to execute processing, which will be described later. The communication unit 15a communicates information with other devices via a communication line. The outer door locking mechanism 16a is a mechanism that locks the outer door 21a. The locking mechanism 241a, the light emitting unit 242a, the RFID reader 243a, the display operation unit 25a, the RFID reader 26a, and the code reader 27a have already been described with reference to FIG. 2, and therefore will not be described here.

[0047] Here, the information stored in the storage unit 14a will be specifically described. The storage unit 14a stores management information 140a, which is information for managing the holders 31 that are the objects of management by the first key management device 10a. Although not shown, the storage unit 14a also stores the processing history of each process. In the following description, the management information 140a and the processing history are stored in the storage unit 14a, but this is not limiting. The management information 140a and the processing history may be stored in another device such as the management server 50.

[0048] Next, the configuration of the control unit 11a will be specifically described. The control unit 11a includes an RFID information acquisition unit 110a, a locking mechanism control unit 111a, and a locking / unlocking control unit 112a. The control unit 11a further includes a light emission control unit 113a, a storage detection unit 114a, and a communication control unit 115a. The control unit 11a further includes a display control unit 116a, an operation reception unit 117a, and a storage control unit 118a.

[0049] The RFID information acquisition unit 110a acquires the RFID information read from the IC tag 34 of the holder 31 by the RFID reader 26a. The lock mechanism control unit 111a controls the lock mechanism 241a so as to prohibit or permit removal of the holder 31 from the individual storage unit 24a.

[0050] The locking / unlocking control unit 112a controls the outer door locking mechanism 16a to lock or unlock the outer door 21a.

[0051] Specifically, suppose that the RFID information acquired by the RFID information acquisition unit 110a is subject to management by the first key management device 10a. Then, the locking / unlocking control unit 112a controls to unlock the outer door 21a. In this case, the locking / unlocking control unit 112a is an example of a function of the control unit that controls to unlock the door when the identification information read by the reading unit is the identification information of the holding unit of the storage target by the storage unit.

[0052] Furthermore, suppose that the RFID information acquired by the RFID information acquisition unit 110a is not subject to management by the first key management device 10a. In this case, the locking / unlocking control unit 112a controls so as not to unlock the outer door 21a. In this case, the locking / unlocking control unit 112a is an example of a function of the control unit that controls so as not to unlock the door when the identification information read by the reading unit is not the identification information of the holding unit of the storage target by the storage unit. Note that the locking / unlocking control unit 112a does not generally unlock the outer door 21a if the RFID information is outside the management target. The following description will be based on this assumption of operation. However, the locking / unlocking control unit 112a may also control the outer door 21a to be unlocked. In other words, the locking / unlocking control unit 112a may allow a holder 31 outside the management target to be temporarily inserted into the individual storage unit 24a. In this case, however, the memory unit 14a stores a history that a holder 31 outside the management target has been inserted into the individual storage unit 24a. In this case, the locking / unlocking control unit 112a is an example of a function of the control unit that controls the door to be unlocked if the identification information read by the reading unit is not the identification information of the holding unit of the storage target.

[0053] The light emission control unit 113a controls the light emitting unit 242a to turn on or off. Specifically, when the lock mechanism control unit 111a permits removal of the holder 31 from the individual storage unit 24a, the light emission control unit 113a controls the light emitting unit 242a provided on the inner door 22a of the individual storage unit 24a to light up. Furthermore, suppose that the storage detection unit 114a detects that the holder 31 has been removed from the individual storage unit 24a. In response, the light emission control unit 113a controls the light emitting unit 242a provided on the inner door 22a of the individual storage unit 24a to turn off.

[0054] The storage detection unit 114a detects removal of the holder 31 from the individual storage unit 24a or loading of the holder 31 into the individual storage unit 24a. Furthermore, the storage detection unit 114a acquires RFID information that the RFID reader 243a reads from the IC tag 34 of the holder 31. Specifically, the storage detection unit 114a acquires this RFID information when the holder 31 is loaded into the individual storage unit 24a.

[0055] The communication control unit 115a receives information from other devices and transmits information to other devices via the communication unit 15a.

[0056] The display control unit 116a controls the display of information on the display operation unit 25a. Specifically, suppose that the RFID information acquired by the RFID information acquisition unit 110a is outside the management target of the first key management device 10a. Then, the display control unit 116a controls the display of information indicating that the holder 31 read by the RFID reader 26a is outside the management target. In other words, the display control unit 116a controls the display operation unit 25a to display such information. The display control unit 116a is an example of a function of the control unit that, when the identification information read by the reading unit is not the identification information of the holder to be stored by the storage unit, controls the output unit to output information to that effect.

[0057] The operation receiving unit 117a receives operations performed by the administrator or the user on the display operation unit 25a.

[0058] The storage control unit 118a controls writing of data to the storage unit 14a and reading of data from the storage unit 14a.

[0059] Specifically, the storage control unit 118a writes the management information 140a and the processing history of each process into the storage unit 14a. Suppose that the RFID information acquired by the RFID information acquisition unit 110a is outside the scope of management by the first key management device 10a. Then, suppose that the locking / unlocking control unit 112a controls the outer door 21a to be unlocked. Then, the memory control unit 118a stores in the memory unit 14a a history indicating that the holder 31 outside the scope of management has been inserted into the individual storage unit 24a. In this case, the memory control unit 118a is an example of a function of the control unit that, when the identification information read by the reading unit is not the identification information of the holder to be stored by the storage unit, records information indicating that.

[0060] Furthermore, the storage control unit 118a reads out the management information 140a from the storage unit 14a, and then determines whether or not the RFID information acquired by the RFID information acquisition unit 110a is included in the management information 140a. Assume that it is determined that the RFID information acquired by the RFID information acquisition unit 110a is included in the management information 140a. Then, the storage control unit 118a determines that the RFID information acquired by the RFID information acquisition unit 110a is subject to management by the first key management device 10a. Assume that it is determined that the RFID information acquired by the RFID information acquisition unit 110a is not included in the management information 140a. Then, the storage control unit 118a determines that the RFID information acquired by the RFID information acquisition unit 110a is not subject to management by the first key management device 10a.

[0061] As described above, the control unit 11a is an example of a control unit that performs control for managing the holding unit of the storage target by the storage unit based on the identification information read by the reading unit.

[0062] (Specific content of management information) 6 is a diagram showing an example of the management information 140a. As shown in the diagram, the management information 140a is information that associates a holder number, RFID information, an authority holder, and a status.

[0063] The holder number is a number that identifies the holder 31. The holder number is also identification information of the holder 31, but unlike RFID information, it is identification information that can be recognized by humans. The RFID information is information that can be read by the RFID reader 26a and is possessed by the holder 31 having the corresponding holder number. The RFID information is also identification information of the holder 31, but unlike the holder number, it is identification information that cannot be recognized by humans but can be recognized by machines. The authorized user is information about a user who has the authority to retrieve the folder 31 with the corresponding folder number. The status is information indicating whether the folder 31 with the corresponding folder number is currently stored in the individual storage section 24a.

[0064] In the figure, for example, it is shown that the holder 31 with the holder number "1" has RFID information "A1234." It also shows that the holder 31 can be taken out by "Tanaka" and "Sato." It also shows that the holder 31 is currently "stored" in the individual storage section 24a.

[0065] (Operation of the first key management device) 7 is a flowchart showing an example of the operation of the first key management device 10a in the first embodiment. Here, the example of the operation of the first key management device 10a will be described as an example of the operation of the control unit 11a of the first key management device 10a. This operation starts when the user holds the IC tag 34 of the holder 31 to be returned over the RFID reader 26a.

[0066] As shown in the figure, in the control unit 11a, first, the RFID information acquisition unit 110a acquires RFID information (step 321). Specifically, the RFID reader 26a reads the RFID information from the IC tag 34 of the holder 31 held by the user. Then, the RFID information acquisition unit 110a acquires this RFID information from the RFID reader 26a.

[0067] Next, the storage control unit 118a determines whether the RFID information acquired in step 321 is a management target (step 322). Specifically, the storage control unit 118a may make this determination by referring to the management information 140a stored in the storage unit 14a. For example, if the RFID information is included in the management information 140a, the storage control unit 118a may determine that the RFID information is a management target. If the RFID information is not included in the management information 140a, the storage control unit 118a may determine that the RFID information is not a management target.

[0068] Assume that it is determined in step 322 that the RFID information is subject to management (YES in step 322), and then the locking / unlocking control unit 112a controls the outer door locking mechanism 16a to unlock the outer door 21a (step 323). Then, the storage detection unit 114a determines whether or not the holder 31 is loaded in any of the plurality of individual storage units 24a (step 324).

[0069] If it is not determined in step 324 that the holder 31 is loaded in the individual storage section 24a (NO in step 324), the storage detection section 114a then repeats the process of step 324. Assume that it is determined in step 324 that the holder 31 has been loaded into the individual storage section 24a (YES in step 324). Then, the storage control section 118a updates the management information 140a stored in the storage section 14a (step 325). Specifically, the storage control section 118a acquires the RFID information from the storage detection section 114a. Then, the storage control section 118a sets the status of the RFID information in the management information 140a to "storage".

[0070] On the other hand, suppose that it is not determined in step 322 that the RFID information is a management target (NO in step 322). Then, display control unit 116a performs control to display that holder 31 held by the user is not a management target (step 326). Specifically, display control unit 116a performs control to display that fact on display operation unit 25a.

[0071] (effect) In the first embodiment, when the outer door 21a is locked, the holder 31 can be returned by having its RFID information read. This makes it possible to omit authentication of the authorized person when returning the holder 31. Furthermore, in the first embodiment, it is possible to omit the registration of users who may only return items, thereby reducing the burden of user registration and management. Furthermore, in the first embodiment, even when the outer door 21a is locked (locked operation), if the holder 31 is managed by the first key management device 10a, it is possible to have it returned on behalf of another person, improving the operability of the return. In the locked operation, it is also easy to install the first key management device 10a in a place where an unspecified number of people come and go.

[0072] (Variation) After reading the RFID information of the holder 31, the first key management device 10a may prompt the user to input authentication information regardless of whether the holder 31 is registered or unregistered. For example, the authentication information may be input by reading an ID card or inputting an employee number. The first key management device 10a may then record this authentication information in the storage unit 14a as information about the returner.

[0073] The first key management device 10a may store, in the storage unit 14a, an operation history including information indicating that the return was made by reading the RFID.

[0074] The first key management device 10a may store in the storage unit 14a an operation history that further includes information about the user who removed the holder 31. In other words, when the holder 31 is returned by proxy, the user who removed the holder 31 may be held responsible as the person who requested the return.

[0075] The first key management device 10a may indicate the individual storage unit 24a to which the holder 31 should be returned on the display operation unit 25a. Alternatively, the first key management device 10a may indicate the individual storage unit 24a to which the holder 31 should be returned by lighting up the corresponding light-emitting unit 242a.

[0076] Even when the outer door 21a is unlocked, the first key management device 10a may read the RFID information of the holder 31. Then, the first key management device 10a may display, on the display operation unit 25a, the individual storage unit 24a to which the holder 31 should be returned.

[0077] The first key management device 10a may be configured to allow the key 33 to be returned by reading the holder 31. On the other hand, the first key management device 10a may be configured to allow some keys to be returned only upon authentication using an ID card. This embodiment may be applied to the first key management device 10a and the second key management device 10b that directly store the keys 33 without using the holder 31. In this case, the keys 33 are directly stored in the key storage unit 23a of the first key management device 10a and the key storage unit 23b of the second key management device 10b. Also, the IC tag 34 may be attached to or embedded in the key 33 itself, and when the first key management device 10a acquires identification information, the key 33 itself is held over the RFID reader 26a. In this case, the key 33 is an example of an article.

[0078] The first key management device 10a may use an IC tag 34 that uses FeliCa (registered trademark) technology instead of an IC tag 34 equipped with RFID. The first key management device 10a may also use a QR code (registered trademark) instead of an IC tag 34. That is, the first key management device 10a may use any information that can identify the holder 31. This is because it is important to be able to identify the holder 31 operated by the first key management device 10a. When using a QR code, it is advisable to affix, for example, a QR code sticker or the like that includes RFID information to the holder 31.

[0079] [Second embodiment] (overview) The second embodiment is an invention relating to an improvement in the administrator's operation of the first key management device 10a. Specifically, suppose that an administrator wants to register a new holder 31. At that time, the administrator reads the IC tag 34 of the holder 31 to be registered. Then, the first key management device 10a identifies the holder 31 and registers it in the management information. Also, suppose that the administrator collects the holder 31 holding the key 33 after it has been used and returned, and takes it back to the office. At that time, the administrator reads the IC tag 34 of the holder 31 to be collected. The first key management device 10a then identifies the holder 31 and updates the management information. This prevents operational errors that may occur when manually selecting the holder 31 to be collected.

[0080] First, the operation of registering the holder 31 in the first key management device 10a in the second embodiment will be described. The operation of registering the holder 31 is an operation in which, when an administrator loads a new key 33, the administrator registers information about the holder 31 that holds the new key 33. In the first key management device 10a before the second embodiment was applied, when registering a new folder 31, the administrator performed the following operation: The administrator prepared a file containing information about the folder 31 to be registered, for example, in a USB (Universal Serial Bus) memory. Then, the administrator performed an operation to have the first key management device 10a read the file from the USB memory. On the other hand, in the first key management device 10a after the second embodiment is applied, when registering a new holder 31, the administrator performs the following operation: That is, the administrator performs an operation to have the RFID reader 26a read the RFID information of the holder 31 to be registered.

[0081] Specifically, the administrator holds the management QR code over the code reader 27a. The first key management device 10a then displays a management menu screen on the display operation unit 25a. The management menu screen includes a holder registration button (not shown). Assume that the administrator touches the holder registration button on the management menu screen. The first key management device 10a then displays, for example, a message on the display operation unit 25a prompting the administrator to read the holder 31. Assume that the administrator then causes the RFID reader 26a to read the IC tag 34 of the holder 31 to be registered. The first key management device 10a then displays a holder number input screen on the display operation unit 25a.

[0082] FIG. 8 is a diagram showing an example of a holder number input screen 210. As shown in the figure, the holder number input screen 210 includes a holder number input area 211 and an end button 215. The holder number input area 211 is an area for inputting a holder number. Here, the holder number is a number that can be recognized by a human (administrator or user). Because the RFID information read from the IC tag 34 of the holder 31 is difficult for humans to recognize, the holder 31 is also assigned a holder number. Assume that the administrator inputs the holder number in the holder number input area 211 and presses the end button 215. Then, the first key management device 10a associates the RFID information read by the RFID reader 26a with the holder number and registers them.

[0083] Next, a description will be given of the operation of collecting the holder 31 in the first key management device 10a in the second embodiment. The operation of collecting the holder 31 is an operation in which the administrator collects the holder 31 that the user has put into the return box 29a. In the first key management device 10a before the second embodiment was applied, the administrator performed the following operation when collecting the returned folder 31. That is, the administrator performed an operation to specify the folder 31 to be collected by operating the screen. On the other hand, in the first key management device 10a after the second embodiment is applied, when the administrator collects the returned holder 31, the administrator performs the following operation: That is, the administrator performs an operation to have the RFID reader 26a read the RFID information of the holder 31 to be collected.

[0084] Specifically, the administrator removes the holder 31 holding the key 33 from the return box 29a. At this time, the administrator may remove multiple holders 31. Next, the administrator holds the collection QR code over the code reader 27a. The first key management device 10a then displays a collection operation screen on the display operation unit 25a.

[0085] FIG. 9 is a diagram showing an example of a collection operation screen 220. As shown in the figure, the collection operation screen 220 includes a holder number display area 222, a status display area 223, and a lending period display area 224. The collection operation screen 220 further includes an end button 225. Assume that the administrator has the RFID reader 26a read the IC tag 34 of the holder 31 to be collected. The first key management device 10a then displays a collection mark 221 linked to the holder number of the holder 31. Thereafter, assume that the administrator checks the holder 31 read by the RFID reader 26a and presses the end button 225. The first key management device 10a then deletes the RFID information read by the RFID reader 26a from the management information.

[0086] (Functional configuration of the first key management device) 10 is a block diagram showing an example of the functional configuration of a first key management device 10a according to the second embodiment. As shown in the figure, the first key management device 10a includes a control unit 12a, a storage unit 14a, a communication unit 15a, and an outer door locking mechanism 16a. The first key management device 10a further includes a locking mechanism 241a, a light-emitting unit 242a, and an RFID reader 243a. The first key management device 10a further includes a display operation unit 25a, an RFID reader 26a, and a code reader 27a.

[0087] The control unit 12a includes an arithmetic circuit such as a CPU, etc. The control unit 12a controls each unit of the first key management device 10a in accordance with an operation program stored in the storage unit 14a. The storage unit 14a includes a ROM, a RAM, etc. The storage unit 14a stores an operation program for the control unit 12a. The storage unit 14a is also used as a work area when the control unit 12a performs control processing. The operation program includes a program for the control unit 12a to execute processing described below. The communication unit 15a communicates information with other devices via a communication line. The outer door locking mechanism 16a is a mechanism that locks the outer door 21a. The locking mechanism 241a, the light emitting unit 242a, the RFID reader 243a, the display operation unit 25a, the RFID reader 26a, and the code reader 27a have already been described with reference to FIG. 2, and therefore will not be described here.

[0088] Here, the information stored in the storage unit 14a is the same as that described in the first embodiment, and therefore a description thereof will be omitted.

[0089] Next, the configuration of the control unit 12a will be specifically described. The control unit 12a includes an RFID information acquisition unit 120a, a locking mechanism control unit 121a, and a locking / unlocking control unit 122a. The control unit 12a further includes a light emission control unit 123a, a storage detection unit 124a, and a communication control unit 125a. The control unit 12a further includes a display control unit 126a, an operation reception unit 127a, a memory control unit 128a, and a code processing unit 129a.

[0090] The RFID information acquisition unit 120a and the lock mechanism control unit 121a are similar to the RFID information acquisition unit 110a and the lock mechanism control unit 111a in the first embodiment, and therefore a description thereof will be omitted here. The locking / unlocking control unit 122a controls the outer door locking mechanism 16a to lock or unlock the outer door 21a. The light emission control unit 123a, storage detection unit 124a, and communication control unit 125a are similar to the light emission control unit 113a, storage detection unit 114a, and communication control unit 115a in the first embodiment, and therefore their description will be omitted here.

[0091] The display control unit 126a controls the display of information on the display operation unit 25a.

[0092] Specifically, it is assumed that the QR code (registered trademark) acquired by the code processing unit 129a is an administration QR code. Then, the display control unit 126a controls the display operation unit 25a to display an administration menu screen. Thereafter, it is assumed that the operation accepting unit 127a accepts an operation to press a holder registration button on the administration menu screen. Then, the display control unit 126a controls the display operation unit 25a to display a holder number input screen 210.

[0093] Also, if the QR code acquired by the code processing unit 129a is a collection QR code, the display control unit 126a performs control so that a collection operation screen 220 is displayed on the display operation unit 25a. Thereafter, it is assumed that the RFID information acquired by the RFID information acquisition unit 120a is a target for management by the first key management device 10a. Then, the display control unit 126a controls the display operation unit 25a to display a collection mark 221 on the collection operation screen 220. In this case, the display operation unit 25a is an example of an output unit that outputs item information related to the holding unit that is the storage target of the storage unit. The collection mark 221 is an example of information indicating that the identification information has been read. The display control unit 126a is an example of a function of the control unit that controls the output unit to output information indicating that the identification information has been read, in association with the item information related to the holding unit to which the identification information read by the reading unit is attached. Alternatively, suppose that the RFID information acquired by the RFID information acquisition unit 120a is outside the scope of management by the first key management device 10a. In this case, the display control unit 126a controls the display of information indicating that the holder 31 read by the RFID reader 26a is outside the scope of management. In other words, the display control unit 126a controls the display operation unit 25a to display such information.

[0094] The operation accepting unit 127a accepts operations performed by the administrator or the user on the display operation unit 25a. Specifically, the operation accepting unit 127a accepts an operation in which the administrator presses a holder registration button on the management menu screen. The operation accepting unit 127a also accepts an operation in which the administrator inputs a holder number on the holder number input screen 210.

[0095] The storage control unit 128a controls writing of data to the storage unit 14a and reading of data from the storage unit 14a.

[0096] Specifically, the storage control unit 128a writes the management information 140a and the processing history of each process into the storage unit 14a. Assume that the QR code acquired by the code processing unit 129a is a management QR code. Assume that the RFID information acquisition unit 120a acquires RFID information. Assume also that the operation acceptance unit 127a accepts an operation to input a holder number on the holder number input screen 210. Then, the storage control unit 128a registers the correspondence between the RFID information and the holder number in the management information 140a stored in the storage unit 14a. As a result, the storage control unit 128a makes the RFID information a management target of the first key management device 10a. In this case, the storage control unit 128a is an example of a function of the control unit that manages the identification information read by the reading unit as identification information of the holding unit of the storage target by the storage unit. The storage control unit 128a is an example of a function of the control unit that manages the identification information read by the reading unit as identification information of the holding unit of the storage target by the storage unit by registering information that associates the identification information read by the reading unit with item information related to the holding unit to which the identification information is attached. Assume that the QR code acquired by the code processing unit 129a is a collection QR code. Assume that the RFID information acquired by the RFID information acquisition unit 120a is a target for management by the first key management device 10a. Then, the storage control unit 128a deletes the association between the RFID information and the holder number from the management information 140a stored in the storage unit 14a. As a result, the storage control unit 128a excludes the RFID information from the target for management by the first key management device 10a. In this case, the storage control unit 128a is an example of a function of the control unit that manages the identification information read by the reading unit as the identification information of a holding unit that is not a target for storage by the storage unit. The storage control unit 128a is an example of a function of the control unit that manages the identification information read by the reading unit as the identification information of a holding unit that is not a target for storage by the storage unit by deleting information that associates the identification information read by the reading unit with item information related to the holding unit to which the identification information is attached.

[0097] Furthermore, the storage control unit 128a reads out the management information 140a from the storage unit 14a, and then determines whether or not the RFID information acquired by the RFID information acquisition unit 120a is included in the management information 140a. Assume that it is determined that the RFID information acquired by the RFID information acquisition unit 120a is included in the management information 140a. Then, the storage control unit 128a determines that the RFID information acquired by the RFID information acquisition unit 120a is subject to management by the first key management device 10a. Assume that it is determined that the RFID information acquired by the RFID information acquisition unit 120a is not included in the management information 140a. In this case, the storage control unit 128a determines that the RFID information acquired by the RFID information acquisition unit 120a is not subject to management by the first key management device 10a.

[0098] The code processing unit 129a acquires the QR code read by the code reader 27a. Then, the code processing unit 129a determines whether the acquired code is a management QR code or a collection QR code. The code processing unit 129a may store, for example, a management QR code and a collection QR code. Then, the code processing unit 129a may make the determination by comparing the acquired code with these stored codes.

[0099] As described above, the control unit 12a is an example of a control unit that performs control for managing the holding units of the storage target by the storage unit based on the identification information read by the reading unit.

[0100] (Operation of the first key management device) 11A and 11B are flowcharts showing an example of the operation of the first key management device 10a in the second embodiment. Here, the example of the operation of the first key management device 10a will be explained as an example of the operation of the control unit 12a of the first key management device 10a. This operation starts when the administrator holds a QR code (registered trademark) over the code reader 27a.

[0101] 11A, in the control unit 12a, first, the code processing unit 129a acquires a QR code (step 341). Specifically, the code reader 27a reads the QR code held up by the administrator. Then, the code processing unit 129a acquires this QR code from the code reader 27a.

[0102] Next, the code processing unit 129a determines whether the QR code acquired in step 341 is a management QR code (step 342). Specifically, the code processing unit 129a may store a management QR code in advance. Then, the code processing unit 129a may determine whether the acquired QR code matches this stored management QR code.

[0103] Assume that it is determined in step 342 that the QR code is an administration QR code. Then, the display control unit 126a controls the display operation unit 25a to display an administration menu screen (step 343). This allows the administrator to press the holder registration button on the administration menu screen. Then, the operation accepting unit 127a determines whether the holder registration button has been pressed on the administration menu screen (step 344). If it is determined that the holder registration button has not been pressed in step 344, the operation receiving unit 127a then repeats the process of step 344. Assume that it is determined in step 344 that the holder registration button has been pressed. As a result, the administrator holds the IC tag 34 of the holder 31 to be registered over the RFID reader 26a. Then, the RFID information acquisition unit 120a acquires the RFID information (step 345). Specifically, the RFID reader 26a reads the RFID information from the IC tag 34 of the holder 31 held by the administrator. Then, the RFID information acquisition unit 120a acquires this RFID information from the RFID reader 26a.

[0104] Next, the display control unit 126a controls the display operation unit 25a to display the folder number input screen 210 (step 346). This allows the administrator to input a folder number on the folder number input screen 210 and press the end button 215. Then, the operation accepting unit 127a accepts the folder number input on the folder number input screen 210 (step 347). Then, the storage control unit 128a associates the RFID information with the holder number and registers them (step 348). Specifically, the storage control unit 128a identifies the RFID information acquired in step 345. The storage control unit 128a also identifies the holder number accepted in step 347. The storage control unit 128a then includes the association between the RFID information and the holder number in the management information 140a stored in the storage unit 14a.

[0105] Thereafter, the control unit 12a determines whether or not there are any more folders 31 to be registered (step 349). If it is determined in step 349 that there are still more folders 31 to be registered, the control unit 12a returns the process to step 345. On the other hand, if it is determined in step 349 that there is no folder 31 to be registered, the control unit 12a ends the process.

[0106] On the other hand, suppose that it is determined in step 342 that the QR code is not a management QR code. Then, as shown in FIG. 11B, the code processing unit 129a determines whether or not the QR code acquired in step 341 is a collection QR code (step 351). Specifically, it is preferable that the code processing unit 129a stores a collection QR code in advance. Then, it is preferable that the code processing unit 129a determines whether or not the acquired QR code matches this stored collection QR code.

[0107] Assume that it is determined in step 351 that the QR code is not a collection QR code. In this case, the code processing unit 129a returns the process to step 341 in Fig. 11A.

[0108] Assume that it is determined that the QR code is a collection QR code in step 351. Then, the display control unit 126a controls the display operation unit 25a to display the collection operation screen 220 (step 352). As a result, the administrator holds the IC tag 34 of the holder 31 to be registered over the RFID reader 26a. Then, the RFID information acquisition unit 120a acquires the RFID information (step 353). Specifically, the RFID reader 26a reads the RFID information from the IC tag 34 of the holder 31 held by the administrator. Then, the RFID information acquisition unit 120a acquires this RFID information from the RFID reader 26a.

[0109] Next, the storage control unit 128a determines whether the RFID information acquired in step 353 is a management target (step 354). Specifically, the storage control unit 128a may make this determination by referring to the management information 140a stored in the storage unit 14a. For example, if the RFID information is included in the management information 140a, the storage control unit 128a may determine that the RFID information is a management target. If the RFID information is not included in the management information 140a, the storage control unit 128a may determine that the RFID information is not a management target.

[0110] Assume that it is determined in step 354 that the RFID information is a management target. Then, the display control unit 126a controls the display operation unit 25a to display a collection mark 221 (step 355). Specifically, the storage control unit 128a identifies the holder number corresponding to the RFID information acquired in step 353. The storage control unit 128a may perform this identification by referring to the management information 140a stored in the storage unit 14a. Then, the display control unit 126a controls the display of the collection mark 221 for this holder number on the collection operation screen 220.

[0111] On the other hand, suppose that it is not determined in step 354 that the RFID information is a management target. Then, the display control unit 126a performs control to display a message that the holder 31 held by the user is not a management target (step 356). Specifically, the display control unit 126a performs control to display a message to that effect on the display operation unit 25a.

[0112] Thereafter, the control unit 12a determines whether or not there are any more holders 31 to be collected (step 357). If it is determined in step 357 that there are still more holders 31 to be collected, the control unit 12a returns the process to step 353. On the other hand, suppose that it is determined in step 357 that there are no more folders 31 to be collected. Then, the administrator presses the end button 225 on the collection operation screen 220. This causes the storage control unit 128a to delete the information of the folder 31 on which the collection mark 221 is displayed (step 358). Specifically, the storage control unit 128a deletes the correspondence between the RFID information and the folder number related to that folder 31 from the management information 140a. Then, the control unit 128a ends the process.

[0113] (effect) In the second embodiment, when registering a folder 31, it is not necessary to create a CSV file for registration. Furthermore, in the second embodiment, when registering the folder 31, it is not necessary to prepare a USB memory in which a file for registration is stored. Furthermore, in the second embodiment, the possibility of making a registration error when registering the holder 31 is reduced.

[0114] In the second embodiment, when collecting the holder 31, there is no need to input information for identifying the holder 31 to be collected, which reduces the number of operational operations. Furthermore, in the second embodiment, when collecting the holders 31, it is not necessary to perform an operation of selecting the holders 31 to be collected, thereby reducing the number of operations required when collecting the holders 31. Furthermore, in the second embodiment, when collecting the holders 31, the possibility of erroneously selecting the holders 31 to be collected decreases.

[0115] (Variation) The second embodiment may be applied to an item management device that manages items in multiple boxes. That is, an IC tag may be attached to an item managed by the item management device, and an RFID reader may be installed in the item management device. This makes it possible to manage the removal and return of items.

[0116] The administrator may unlock the outer door 21a by reading the IC tag 34 with the RFID reader 26a. Then, the administrator may return the key 33 to the return box 29a. This makes all of the individual storage sections 24a of the inner door 22a available for loan. Therefore, the first key management device 10a can loan many keys at the same time. This embodiment may be applied to the first key management device 10a and the second key management device 10b that directly store the keys 33 without using the holder 31. In this case, the keys 33 are directly stored in the key storage unit 23a of the first key management device 10a and the key storage unit 23b of the second key management device 10b. Also, the IC tag 34 may be attached to or embedded in the key 33 itself, and when the first key management device 10a acquires identification information, the key 33 itself is held over the RFID reader 26a. In this case, the key 33 is an example of an article.

[0117] The first key management device 10a may use an IC tag 34 that uses FeliCa (registered trademark) technology instead of an IC tag 34 equipped with RFID. The first key management device 10a may also use a QR code (registered trademark) instead of an IC tag 34. That is, the first key management device 10a may use any information that can identify the holder 31. This is because it is important to be able to identify the holder 31 operated by the first key management device 10a. When using a QR code, it is advisable to affix, for example, a QR code sticker or the like that includes RFID information to the holder 31.

[0118] [Third embodiment] (overview) The third embodiment is an invention relating to a procedure for loading a key removed from the second key management device 10b into the first key management device 10a. Specifically, when reservation information for key 33 is entered into management client 40, second key management device 10b unlocks key 33. Next, when key 33 is removed by second key management device 10b, reservation information is sent to first key management device 10a. After that, when key 33 is held up and loaded by first key management device 10a, the loading process is completed and a QR code (registered trademark) is sent to the user. This procedure eliminates manual input by the administrator, reducing the workload and reducing the likelihood of loading errors.

[0119] FIG. 12 is a schematic diagram specifically showing such a procedure. As shown in the figure, first, an administrator enters reservation information for the key 33 into the management client 40 in the office (S41). Here, the reservation information for the key 33 includes information about the user who reserved the key 33, the type of construction equipment for which the key 33 will be used, the rental period for the key 33, etc. The reservation information for the key 33 is then sent to the management server 50.

[0120] As a result, the management server 50 transmits a request to unlock the key 33 to the second key management device 10b in the office (S42). Specifically, the management server 50 transmits a request to unlock the key 33 to be used for the type of construction machine included in the reservation information. In response, the second key management device 10b unlocks the key 33. Also, in the second key management device 10b, for example, the light-emitting unit 242b of the individual storage unit 24b in which the key 33 is loaded lights up. This allows the manager to recognize the individual storage unit 24b that stores the key 33 to be used for the type of construction machine included in the reservation information.

[0121] Next, the administrator removes the holder 31 holding the key 33 from the second key management device 10b. The second key management device 10b then transmits the RFID information of the removed holder 31 to the management server 50 (S43). As a result, the management server 50 transmits the reservation information and RFID information to the first key management device 10a located outdoors (S44). Then, the first key management device 10a receives the reservation information and RFID information from the management server 50.

[0122] Next, the administrator carries the holder 31 removed from the second key management device 10b to the first key management device 10a. The administrator then holds the holder 31 over the RFID reader 26a of the first key management device 10a (S45). The first key management device 10a then reads the RFID information of the holder 31 using the RFID reader 26a. The first key management device 10a then compares the received RFID information with the read RFID information. If the RFID information matches, the first key management device 10a unlocks the outer door 21a. The administrator then loads the holder 31 into the individual storage unit 24a of the first key management device 10a (S46).

[0123] Thereafter, the first key management device 10a transmits a reservation completion notice for the key 33 to the management server 50 (S47). Here, the reservation completion notice for the key 33 may include, for example, the number of the individual storage unit 24a in which the holder 31 holding the key 33 is loaded.

[0124] As a result, the management server 50 transmits a QR code (registered trademark) to the user (S48). Specifically, the management server 50 may transmit a QR code including, for example, the number of the individual storage unit 24a to the user. The management server 50 may also transmit the QR code by email to, for example, a mobile terminal of the user identified based on the reservation information. The user then has the code reader 27a of the first key management device 10a read the QR code and retrieve the reserved key 33.

[0125] (Functional configuration of the first key management device) 13 is a block diagram showing an example of the functional configuration of a first key management device 10a according to the third embodiment. As shown in the figure, the first key management device 10a includes a control unit 13a, a storage unit 14a, a communication unit 15a, and an outer door locking mechanism 16a. The first key management device 10a further includes a locking mechanism 241a, a light-emitting unit 242a, and an RFID reader 243a. The first key management device 10a further includes a display operation unit 25a, an RFID reader 26a, and a code reader 27a.

[0126] The control unit 13a includes an arithmetic circuit such as a CPU, etc. The control unit 13a controls each unit of the first key management device 10a in accordance with an operation program stored in the storage unit 14a. The storage unit 14a includes a ROM, a RAM, etc. The storage unit 14a stores an operation program for the control unit 13a. The storage unit 14a is also used as a work area when the control unit 13a performs control processing. The operation program includes a program for the control unit 13a to execute processing described below. The communication unit 15a communicates information with the management server 50 via a communication line. The outer door locking mechanism 16a is a mechanism that locks the outer door 21a. The locking mechanism 241a, the light emitting unit 242a, the RFID reader 243a, the display operation unit 25a, the RFID reader 26a, and the code reader 27a have already been described with reference to FIG. 2, and therefore will not be described here.

[0127] Here, the information stored in the storage unit 14a is the same as that described in the first embodiment, and therefore a description thereof will be omitted.

[0128] Next, the configuration of the control unit 13a will be described in detail. The control unit 13a includes an RFID information acquisition unit 130a, a locking mechanism control unit 131a, and a locking / unlocking control unit 132a. The control unit 13a further includes a light emission control unit 133a, a storage detection unit 134a, and a communication control unit 135a. The control unit 13a further includes a display control unit 136a, an operation reception unit 137a, a memory control unit 138a, and a determination unit 139a.

[0129] The RFID information acquisition unit 130a and the lock mechanism control unit 131a are similar to the RFID information acquisition unit 110a and the lock mechanism control unit 111a in the first embodiment, and therefore a description thereof will be omitted here.

[0130] The locking / unlocking control unit 132a controls the outer door locking mechanism 16a to lock or unlock the outer door 21a.

[0131] Specifically, suppose that the RFID information acquired by the RFID information acquisition unit 130a has been reserved by the first key management device 10a. Then, the locking / unlocking control unit 132a controls the outer door 21a to be unlocked. In this case, the locking / unlocking control unit 132a is an example of a function of the control unit that controls the door to be unlocked when the identification information read by the reading unit is the identification information of the holding unit that is reserved for storage by the storage unit.

[0132] Also, if the RFID information acquired by the RFID information acquisition unit 130a is not reserved by the first key management device 10a, the locking / unlocking control unit 132a controls the outer door 21a not to be unlocked.

[0133] The light emission control unit 133a and the storage detection unit 134a are the same as the light emission control unit 113a and the storage detection unit 114a in the first embodiment, and therefore a description thereof will be omitted here.

[0134] The communication control unit 135a receives information from the management server 50 and transmits information to the management server 50 via the communication unit 15a.

[0135] Specifically, the communication control unit 135a receives reservation information and RFID information from the management server 50. Here, the reservation information is information input by the administrator to the management client 40. The RFID information is information transmitted by the second key management device 10b to the management server 50 when the reserved key 33 is extracted. In this case, the second key management device 10b is an example of a second storage unit. The communication control unit 135a is an example of a function of the control unit that identifies the identification information output by the second storage unit as the identification information of the holding unit that is reserved for storage by the storage unit.

[0136] Furthermore, the communication control unit 135a transmits a reservation completion to the management server 50. Here, the reservation completion is information indicating that the reserved key 33 has been loaded into the individual storage unit 24a.

[0137] The display control unit 136a controls the display of information on the display operation unit 25a. The operation receiving unit 137a receives operations performed by the administrator or the user on the display operation unit 25a. The storage control unit 138a controls writing of data to the storage unit 14a and reading of data from the storage unit 14a.

[0138] The determination unit 139a identifies the RFID information acquired by the RFID information acquisition unit 130a. The determination unit 139a also identifies the RFID information received by the communication control unit 135a. The determination unit 139a then determines whether or not these pieces of RFID information match. If it is determined that these pieces of RFID information match, the determining unit 139a then determines that the RFID information acquired by the RFID information acquiring unit 130a has been reserved in the first key management device 10a. If it is determined that these pieces of RFID information do not match, the determining unit 139a then determines that the RFID information acquired by the RFID information acquiring unit 130a has not been reserved in the first key management device 10a.

[0139] As described above, the control unit 13a is an example of a control unit that performs control for managing the holding unit of the storage target by the storage unit based on the identification information read by the reading unit.

[0140] (Functional configuration of the second key management device) 14 is a block diagram showing an example of the functional configuration of a second key management device 10b according to the third embodiment. As shown in the figure, the second key management device 10b includes a control unit 13b, a storage unit 14b, and a communication unit 15b. The second key management device 10b further includes a locking mechanism 241b, a light-emitting unit 242b, and an RFID reader 243b. The second key management device 10b further includes a display operation unit 25b. The second key management device 10b is an example of a second storage unit that stores a holding unit.

[0141] The control unit 13b includes an arithmetic circuit such as a CPU, etc. The control unit 13b controls each unit of the second key management device 10b in accordance with an operation program stored in the storage unit 14b. The storage unit 14b includes a ROM, a RAM, etc. The storage unit 14b stores an operation program for the control unit 13b. The storage unit 14b is also used as a work area when the control unit 13b performs control processing. The operation program includes a program for the control unit 13b to execute processing described below. The communication unit 15b communicates information with the management server 50 via a communication line. The lock mechanism 241b, the light emitting unit 242b, the RFID reader 243b, and the display operation unit 25b have already been described with reference to FIG. 3, and therefore, description thereof will be omitted here.

[0142] Next, the configuration of the control unit 13b will be specifically described. The control unit 13b includes a lock mechanism control unit 131b. The control unit 13b further includes a light emission control unit 133b, a storage detection unit 134b, and a communication control unit 135b. The control unit 13b further includes a display control unit 136b, an operation reception unit 137b, and a storage control unit 138b.

[0143] The lock mechanism control unit 131b controls the lock mechanism 241b so as to prohibit or permit removal of the holder 31 from the individual storage unit 24b.

[0144] Specifically, suppose the communication control unit 135b receives a request to unlock the holder 31 from the management server 50. The locking mechanism control unit 131b then controls the locking mechanism 241b to permit removal of the holder 31 from the individual storage unit 24b. The request to unlock the holder 31 includes the number of the individual storage unit 24b to be unlocked. The locking mechanism control unit 131b then permits removal of the holder 31 from the individual storage unit 24b with that number. The request to unlock the holder 31 also includes the type of construction machine for which the key 33 held by the holder 31 is used. The locking mechanism control unit 131b then identifies the individual storage unit 24b that is pre-associated with that type of construction machine. The locking mechanism control unit 131b then permits removal of the holder 31 from the identified individual storage unit 24b.

[0145] Also, suppose that the communication control unit 135b does not receive a request to unlock the holder 31 from the management server 50. In this case, the lock mechanism control unit 131b controls the lock mechanism 241b to prohibit removal of the holder 31 from the individual storage unit 24b.

[0146] The light emission control unit 133b controls the light emitting unit 242b to turn on or off. Specifically, suppose the lock mechanism control unit 131b permits removal of the holder 31 from the individual storage unit 24b. Then, the light-emission control unit 133b controls the light-emitting unit 242b provided in that individual storage unit 24b to light up. At this time, the holder 31 permitted for removal is the holder 31 that holds the key 33 used for a specified type of construction machine. Here, the type of construction machine is included in the reservation information input by the management client 40. In this case, the management client 40 is an example of a reception unit that accepts the type of holder. The light-emission control unit 133b is an example of a function of the second storage unit that notifies the user of the location where the holder of the type accepted by the reception unit should be stored. Furthermore, suppose that the storage detection unit 134b detects that the holder 31 has been removed from the individual storage unit 24b, in which case the light emission control unit 133b controls the light emitting unit 242b provided in that individual storage unit 24b to turn off.

[0147] The storage detection section 134b detects removal of the holder 31 from the individual storage section 24b or loading of the holder 31 into the individual storage section 24b. Furthermore, the storage detection unit 134b acquires RFID information that the RFID reader 243b reads from the IC tag 34 of the holder 31. Specifically, the storage detection unit 134b acquires this RFID information when the holder 31 is loaded into the individual storage unit 24b.

[0148] The communication control unit 135b receives information from the management server 50 and transmits information to the management server 50 via the communication unit 15b.

[0149] Specifically, the communication control unit 135b receives a request to unlock the holder 31 from the management server 50. At this time, the request to unlock the holder 31 may include the number of the individual storage unit 24b to be unlocked. Alternatively, the request to unlock the holder 31 may include the type of construction machine for which the key 33 held by the holder 31 is used.

[0150] Furthermore, the communication control unit 135b transmits RFID information of the holder 31 removed from the individual storage unit 24b to the management server 50. In this case, the communication control unit 135b is an example of a function of the second storage unit that outputs identification information of the holder in response to the removal of the holder. Furthermore, the management server 50 is an example of a transfer unit. The communication control unit 135b is an example of a function of the second storage unit that transmits identification information of the holder to the transfer unit.

[0151] The display control unit 136b controls the display of information on the display operation unit 25b. The operation receiving unit 137b receives operations performed by the administrator or the user on the display operation unit 25b. The storage control unit 138b controls writing of data to the storage unit 14b and reading of data from the storage unit 14b.

[0152] (Management Server Functional Configuration) 15 is a block diagram showing an example of the functional configuration of management server 50 in the third embodiment. As shown in the figure, management server 50 includes a control unit 51, a storage unit 52, a communication unit 53, a display unit 54, and an operation unit 55. Management server 50 is an example of a transfer unit connected to the reception unit and the second storage unit via communication lines, and is also an example of a transfer unit connected to the second storage unit and control unit via communication lines.

[0153] The control unit 51 includes a calculation circuit such as a CPU, etc. The control unit 51 controls each unit of the management server 50 in accordance with an operation program stored in the storage unit 52. The storage unit 52 includes a ROM, a RAM, etc. The storage unit 52 stores an operation program for the control unit 51. The storage unit 52 is also used as a work area when the control unit 51 performs control processing. The operation program includes a program for the control unit 51 to execute processing described below. The communication unit 53 communicates information with other devices via a communication line. Here, the other devices are the management client 40, the first key management device 10a, and the second key management device 10b. The display unit 54 is, for example, a display, and displays various information. The operation unit 55 is, for example, a keyboard or a mouse, and is used by the user to input operation information.

[0154] Next, a specific description will be given of the configuration of the control unit 51. The control unit 51 includes a communication control unit 511 and a code generation unit 512.

[0155] The communication control unit 511 receives information from and transmits information to other devices via the communication unit 53. Here, the other devices are the management client 40, the first key management device 10a, and the second key management device 10b.

[0156] Specifically, the communication control unit 511 receives reservation information for the key 33 accepted by the management client 40 from the management client 40. Here, the reservation information for the key 33 includes information about the user who reserved the key 33, the type of construction equipment for which the key 33 will be used, the rental period for the key 33, etc. In this case, the management client 40 is an example of a reception unit that transmits the type of holding unit to the transfer unit. The communication control unit 511 is an example of a function of the transfer unit that receives the type of holding unit from the reception unit. The communication control unit 511 receives, from the second key management device 10b, the RFID information of the holder 31 extracted by the second key management device 10b. In this case, the communication control unit 511 is an example of a function of the transfer unit that receives the identification information of the holder from the second storage unit. The communication control unit 511 receives from the first key management device 10a a notification that the reservation has been completed when the holder 31 is loaded into the first key management device 10a.

[0157] The communication control unit 511 also transmits a request to unlock the holder 31 to the second key management device 10b. At this time, the request to unlock the holder 31 may include the number of the individual storage unit 24b of the second key management device 10b. The request to unlock the holder 31 may also include the type of construction machine for which the key 33 is used. In this case, the communication control unit 511 is an example of a function of the transfer unit that transmits information for identifying the location where the type holder is stored to the second storage unit. The communication control unit 511 transmits reservation information for the key 33 and RFID information for the holder 31 to the first key management device 10a. Here, the reservation information for the key 33 is received from the management client 40. The RFID information for the holder 31 is received from the second key management device 10b. In this case, the communication control unit 511 is an example of a function of the transfer unit that transmits identification information of the holding unit to the control unit. The communication control unit 511 transmits the QR code (registered trademark) generated by the code generation unit 512 to the mobile terminal of the user.

[0158] The code generation unit 512 generates a QR code for the user to instruct lending of the key 33. The code generation unit 512 may include in the QR code the number of the individual storage unit 24a included in the reservation completion received by the communication control unit 511.

[0159] (Key management system operation) 16 is a sequence diagram showing an example of the operation of the key management system 1 in the third embodiment. Here, the example of the operation of the key management system 1 will be described as an example of the operation of the control unit of the device that constitutes the key management system 1. This operation starts when the management client 40 transmits reservation information input by the administrator to the management server 50.

[0160] As shown in the figure, in the management server 50, first, the communication control unit 511 receives reservation information for the key 33 from the management client 40 (step 501). Specifically, the communication control unit 511 controls the communication unit 53 to receive the reservation information for the key 33 from the management client 40. Here, the reservation information for the key 33 includes information about the user who reserved the key 33, the type of construction machine for which the key 33 will be used, the rental period for the key 33, etc. Next, the communication control unit 511 transmits a request to unlock the key 33 to the second key management device 10b (step 502). Specifically, the communication control unit 511 controls the communication unit 53 to transmit the request to unlock the key 33 to the second key management device 10b.

[0161] As a result, in the second key management device 10b, the communication control unit 135b receives a request to unlock the key 33 from the management server 50 (step 371). Specifically, the communication control unit 135b controls the communication unit 53 to receive a request to unlock the key 33 from the management server 50. Then, the locking mechanism control unit 131b unlocks the holder 31 that holds the key 33 (step 372). Specifically, the locking mechanism control unit 131b controls the locking mechanism 241b to unlock the individual storage unit 24b in which the holder 31 is stored.

[0162] For example, consider a case where the management server 50 holds correspondence information between a construction machine and the individual storage unit 24b in which the key 33 for that construction machine is stored. In this case, the management server 50 uses the correspondence information to identify the individual storage unit 24b in which the key 33 for the construction machine included in the reservation information is stored. The management server 50 then transmits a request to the second key management device 10b to unlock the key 33 stored in this identified individual storage unit 24b. As a result, the second key management device 10b identifies the individual storage unit 24b in which the key 33 for the construction machine included in the reservation information is stored.

[0163] Also, consider a case where the second key management device 10b holds correspondence information between a construction machine and an individual storage unit 24b in which the key 33 for that construction machine is stored. In this case, the management server 50 transmits the type of construction machine included in the reservation information to the second key management device 10b. As a result, the second key management device 10b identifies, using the correspondence information, the individual storage unit 24b in which the key 33 for the construction machine included in the reservation information is stored.

[0164] Next, in the second key management device 10b, the storage detection unit 134b determines whether the holder 31 has been removed (step 373). If it is not determined in step 373 that the holder 31 has been removed, the storage detection unit 134b then repeats the process of step 373. On the other hand, suppose that it is determined in step 373 that holder 31 has been removed. Then, communication control unit 135b transmits the RFID information of holder 31 to management server 50 (step 374). Specifically, storage detection unit 134b identifies the RFID information of holder 31 when holder 31 is removed. Then, communication control unit 135b controls communication unit 15b to transmit the RFID information of holder 31 to management server 50.

[0165] As a result, in the management server 50, the communication control unit 511 receives the RFID information from the second key management device 10b (step 503). Specifically, the communication control unit 511 controls the communication unit 53 to receive the RFID information from the second key management device 10b. Then, the communication control unit 511 transmits the reservation information and the RFID information to the first key management device 10a (step 504). Specifically, the communication control unit 511 controls the communication unit 53 to transmit the reservation information and the RFID information to the first key management device 10a. Here, the reservation information is the information received from the management client 40 in step 501. Furthermore, the RFID information is the information received in step 503.

[0166] As a result, in the first key management device 10a, the communication control unit 135a receives the reservation information and the RFID information from the management server 50 (step 361). Specifically, the communication control unit 135a controls the communication unit 15a to receive the reservation information and the RFID information from the management server 50. Thereafter, the administrator holds the holder 31 removed in step 373 over the RFID reader 26a. The RFID reader 26a then reads the RFID information from the IC tag 34 of the holder 31. The RFID information acquisition unit 130a then acquires the RFID information read by the RFID reader 26a (step 362).

[0167] Next, the determination unit 139a determines whether or not the two pieces of RFID information match (step 363). Here, the two pieces of RFID information are the RFID information received in step 361 and the RFID information acquired in step 362. Assume that it is not determined that the two pieces of RFID information match in step 363. In this case, the control unit 13a ends the process.

[0168] On the other hand, if it is determined that the two pieces of RFID information match in step 363, the locking / unlocking control unit 132a then controls the outer door locking mechanism 16a to unlock the outer door 21a (step 364). Then, the storage detection unit 134a determines whether or not the holder 31 is loaded in any of the plurality of individual storage units 24a (step 365). If it is not determined in step 365 that the holder 31 is loaded in any of the individual storage sections 24a, the storage detection section 134a then repeats the process of step 365. Assume that it is determined in step 365 that the holder 31 has been loaded into one of the multiple individual storage sections 24a. Then, the communication control section 135a transmits a reservation completion to the management server 50 (step 366). Specifically, the communication control section 135a controls the communication section 15a to transmit the reservation completion to the management server 50. Here, the reservation completion may include, for example, the number of the individual storage section 24a in which the holder 31 has been loaded.

[0169] As a result, in the management server 50, the communication control unit 511 receives the reservation completion from the first key management device 10a (step 505). Specifically, the communication control unit 511 controls the communication unit 53 to receive the reservation completion from the first key management device 10a. Next, the code generating unit 512 generates a QR code (registered trademark) (step 506). Here, the QR code may include the number of the individual storage unit 24a included in the reservation completion. Then, communication control unit 511 transmits this QR code to the user (step 507). Specifically, communication control unit 511 controls communication unit 53 to transmit the QR code to the user's mobile terminal, for example, by email.

[0170] (effect) In the third embodiment, the holder 31 holding the key 33 can be loaded into the first key management device 10a if only the holder 31 is present. Furthermore, in the third embodiment, there is no need to manage pairs of holders 31 and QR codes (registered trademark) in order to have an administrator load holders 31. Furthermore, in the third embodiment, the administrator can easily load keys 33 to be lent to multiple users. In other words, the administrator can perform such an operation in the same way as loading keys 33 to be lent to a single user.

[0171] (Variation) Suppose the administrator accidentally removes the key 33 to be lent from the second key management device 10b. In this case, the removal of the key 33 may be canceled by returning the key to the second key management device 10b before loading it into the first key management device 10a. In other words, a special cancellation operation may not be required.

[0172] Assume that the administrator loads the returned key 33 into the second key management device 10b. Here, the returned key 33 may be the key 33 that the user returned to the return box 29a of the first key management device 10a. Alternatively, the returned key 33 may be the key 33 that the user returned directly to an office employee. In this case, the second key management device 10b may send loading information indicating that the holder 31 has been loaded to the management server 50. In response to this, the management server 50 may notify the first key management device 10a that collection has been completed. Then, upon receiving the notification that collection has been completed, the first key management device 10a may delete the reservation information.

[0173] The office employee can complete the collection by simply loading the key 33 into the second key management device 10b. In this case, there is no need to delete the reservation information from the management server 50 or the first key management device 10a.

[0174] This embodiment may be applied to the first key management device 10a and the second key management device 10b that directly store the keys 33 without using the holder 31. In this case, the keys 33 are directly stored in the key storage unit 23a of the first key management device 10a and the key storage unit 23b of the second key management device 10b. Also, the IC tag 34 may be attached to or embedded in the key 33 itself, and when the first key management device 10a acquires identification information, the key 33 itself is held over the RFID reader 26a. In this case, the key 33 is an example of an article.

[0175] The first key management device 10a may use an IC tag 34 that uses FeliCa (registered trademark) technology instead of an IC tag 34 equipped with RFID. The first key management device 10a may also use a QR code (registered trademark) instead of an IC tag 34. That is, the first key management device 10a may use any information that can identify the holder 31. This is because it is important to be able to identify the holder 31 operated by the first key management device 10a. When using a QR code, it is advisable to affix, for example, a QR code sticker or the like that includes RFID information to the holder 31. [Explanation of symbols]
