Description

  The present invention relates to an automatic library system having an unknown book search function.

In the library, but the books are all load presence management in the bibliography database included in the library system have been made, it may return forgotten or lost, stolen, the books for a variety of reasons, such as Shelf mistakes become missing, share This has led to a decrease in property. Also in the library, automatic archive system that automates and return and taken out of the books in conjunction with the library system have been introduced many. In this automatic archive system, staff and Library of the user of the library, along with operating the terminal of the system can perform the removal and return of the books in, but there is an unknown books is caused by operation inconsistent, unknown books Often it is not noticed that has occurred.
This is because, in the automatic archive system, performs a system own load presence management, removal of all of the books, because the store is not performed only at a particular location (teller station), from the books that have been shelved in addition to the automatic archive Unknown books are unlikely to occur. However, since it is expected that an unknown book will be generated due to a mistake in taking out or storing, an unknown book prevention method has been proposed. For example, in Patent Document 1, in order to prevent forgetting to read a barcode when performing book return processing, whether or not the barcode is read is checked when the book is put into a container at the return port, and the barcode is read. Warning information is output when there is no.

In Patent Document 1, when returning a book, whether or not a barcode is read and whether or not the book is stored in a container are confirmed, and a work error is warned. However, unknown books are generated not only by book storage work but also by taking out books or placing work. Thus cause of unknown books are rather than one, even if unknown books has occurred, since the generation factor there are multiple, it requires an enormous amount of time and effort to search for a specific and unknown books cause As a result, maintenance takes time and effort.
The present invention aims to shorten the search time by detecting early that there is a possibility that unknown books are occurring, and to provide an automatic library system that can appropriately maintain and manage books at low cost. For that purpose.

The invention described in claim 1 is a library unit capable of storing a plurality of containers capable of storing a plurality of books, and a depositing / dispensing station for performing a book extraction operation and a storage operation for the containers conveyed from the library unit. In the automatic library system in which the container is stored and unloaded, the library master information including the book master information which is the initial state of the book in advance and the storage date and time and the storage date and time, and the library collection A control unit capable of two-way communication with a library system that performs management, a comparison unit that compares a book state stored in the storage unit with a book state stored in the library system, and a book state by the comparison unit comparison result does the book state stored in the storage unit is "non-load presence", is a library state stored in the library system consistent with "load presence" field And an output means for outputting the unknown library is generated, the comparison of books state by said comparing means is performed by the number of days which is a predetermined interval, extracting date of the unknown book based on the container master information The containers entered and exited during the days output by the output means are listed up .

According to a second aspect of the present invention, in the automatic library system according to the first aspect, the book state stored in the library system is updated in accordance with the retrieval or storage of the book.

According to a third aspect of the present invention, in the automatic library system according to the first aspect, the book state stored in the storage unit is a registration date and time (D1) when the initial state is registered, and this book is obtained from the depositing station. It is updated according to the newly stored new storage date and time (D2).

According to a fourth aspect of the present invention, in the automatic library system according to the first aspect, the book state stored in the storage unit is the book take-out date / time (T1) at which the book was taken out at the deposit / departure station and The book is updated according to the book storage date and time (T2) when the book is stored.
The invention according to claim 5 is the automatic archive system according to any one of claims 1 to 4, further comprising setting means for arbitrarily setting the predetermined interval.

According to the present invention, an unknown book is generated when the comparison result of the comparison means for comparing the book state stored in the library system and the book state stored in the storage unit of the automatic library system does not match. Since the output means outputs this information, the occurrence of an unknown book can be detected early, so that the search can be performed in a short time, the number of unknown books can be reduced, and the book can be maintained and managed appropriately.
According to the present invention, the book data transmitted from the library system to the control unit of the automatic library system, the registration date and time (D1) when the book data is registered, and the book corresponding to the book data are newly stored from the cashier station. When the new storage date / time (D2) is compared with the new storage date / time (D2) and the new storage date / time (D2) is not updated within the predetermined period (D3) from the registration date / time (D1), the book data not updated within the predetermined period (D3) Is output as an unknown book by the output means, so that it is possible to detect the occurrence of unknown books earlier on the basis of the predetermined period (D3), so that the search can be made in a short time, reducing the unknown books, Book maintenance can be done properly.
According to the present invention, the book storage date / time (T2) when the book was taken out at the cashier station and the book storage date / time (T2) at which the book was stored at the cashier station were compared. If the book data not updated within the predetermined time (T3) is not updated within the predetermined time (T3) from the extraction date and time (T1), the output means outputs the book data as an unknown book, so the predetermined time (Т3) As a reference, the occurrence of unknown books can be detected earlier, the search can be performed in a short time, unknown books can be reduced, and book maintenance can be performed appropriately.

(Description of control system)
As shown in FIG. 5, the automatic archive system 1 has a system manager 60 as a control unit having a server function, a station terminal 61 provided in the depositing / dispensing station 10 and functions as a control unit and output means, and functions as a control unit. And a central control panel 62. The system manager 60, the station terminal 61, and the central control panel 62 are composed of computers, and are connected to each other by communication lines. The system manager 60, the station terminal 61, and the central control panel 62 are connected to each other. Each communication of information is possible.

  The system management device 60 is connected to a library system 63 that performs overall library management of the library through a communication line so as to be capable of bidirectional communication, and various information can be transmitted and received between the two. In this embodiment, the library data managed by the library system 63 is transmitted from the library system 63 to the system manager 60. The system manager 60 includes a storage unit 70. The storage unit 70 can update data, and is stored as book master information based on the book data transmitted from the library system 63, and also stores container master information and shelf number master information. That is, the system manager 60 has a database function and a function of sending operation commands of the conveyors constituting the stacker cranes 6A and 6B and the conveying means 50 to the central control panel 62.

  The book master information includes data such as the registration date of the book 16, book ID, title, author name, billing symbol, size, new storage date, book state, container ID, extraction date / time, storage date / time, and the number of extractions. Yes.

The container master information includes data such as a container ID, a container state, a shelf number (unit / column / continuous / stage / front and rear), an empty space, a storage date / time, a storage date / time, and the number of stored books.
The shelf number master information includes data such as a shelf number (unit / column / continuous / stage / front and back), a shelf state, a storage date / time, a shipping date / time, and the like.

Each time the book 16 is taken out or stored at the depositing / dispensing station 10, the system manager 60 sends container master information and a book master from a book take-out notice or store notice from the station terminal 61 and a status notification of each device from the central control panel 62. The information and the shelf number master information are updated, and it is configured to manage the stock status of the books 16 and the containers 15. Then, the system manager 60 transmits the book state data among the updated contents to the library system 63 as event data. That is, each time a book is taken in or out of the automatic library system 1, the book take-out or storage information (notification) is transmitted to the library system 63, and the book state data on the library system 63 side is updated accordingly. The inventory status of the management machine 60 and the library system 63 is configured to match.

  FIG. 6 shows an example of the book retrieval or storage information (notification) sent and received between the system manager 60 and the library system 63, and the book status data associated therewith. Since the library system 63 is outside the range of the automatic library system 1, the book state and event data shown in FIG. 6 are examples, and the details differ depending on the library system 63. Absent.

  The system manager 60 has a function and a container that can search the position of the container 15 in which the books 16 are stored and the empty positions of the racks 2A and 2B by referring to various information stored in the storage unit 70. A function for retrieving the number of empty spaces in 15 and the number of containers 15 having a desired empty space, designation of empty space input from the depositing / dispensing station 10, information on the number of empty containers 15, and a container for storing the book 16 at the depositing / receiving station 10 It has a function of allocating a corresponding container 15 by inputting designated information, and a function of searching for and listing a book that may be an unknown book (unknown candidate book) and saving it as a file. The system manager 60 sends an operation command (transport instruction) to the central control panel 62 so as to transport the designated book 16, the reserved container 15 and the container 15 with the searched unknown candidate book to the depositing / dispensing station 10. It has a function to do. Upon receiving this command, the central control panel 62 controls the operations of the stacker cranes 6A and 6B and the conveying means 50.

  The system manager 60 includes comparison means 71 that compares the book status data stored in the storage unit 70 with the book status data transmitted from the library system 63. The automatic library system 1 generates an unknown book when the comparison result of the book status data transmitted from the library system 63, that is, the book status data of the library system 63 and the book status data stored in the storage unit 70 does not match. Output means for outputting the information. In the present embodiment, this output means corresponds to the system manager 60. The system manager 60 has a function of searching for unknown candidate books and displaying the listed files on a monitor (not shown).

  The central control panel 62 is connected to the crane control panels 6a and 6b mounted on the stacker cranes 6A and 6B and the cart control panels 9a and 9b mounted on the transport carts 9A and 9B so as to be able to communicate wirelessly. The stacker cranes 6A and 6B and the transport carts 9A and 9B are controlled via the control panels 6a and 6b and the cart control panels 9a and 9b. The central control panel 62 controls the container conveyance of the conveyors 7 and 8, the horizontal conveyor 38, the vertical conveyor 39, and the station conveyor 40.

  The station terminal 61 has a function of instructing work in the work of taking out and storing the books 16 at the depositing / dispensing station 10. The station terminal 61 uses the mouse 22 and the keyboard 25 to designate the container 15 for storing the book 16 at the depositing / dispensing station 10, so that the container 15 can be designated as an empty space, the number of empty containers 15, a container ID, etc. A function for inputting search conditions and transmitting the information to the system manager 60 and a function for displaying the search results transmitted from the system manager 60 are provided.

Although the library system 63 is a system unique to the library different from the automatic archive system 1, transmission and reception of various data is sequentially performed with the system manager 60. For example, a library 16 Shelf location is automated library system 1, you must be registered as a library master information books data to the automatic library system 1 side first. Therefore, the book data is transmitted from the library system 63 side to the system management device 60 via the communication line, and is registered in the storage unit 70 as book master information on the automatic library system 1 side. From the system manager 60, each time the book 16 is taken in or out on the automatic library system 1, the book retrieval or storage information (notification) is transmitted to the library system 63, and the library system 63 side receives the book status data accordingly. Is updated. For this reason, if the consistency of the book status data of the book 16 in the system manager 60 and the library system 63 is not taken, that is, they do not match, it is considered that an unknown book may have occurred.

  Therefore, in the automatic library system 1, the unknown book extraction process shown in the flowchart of FIG. In FIG. 7, in step ST1, the comparison means 71 compares the library state data of the library system 63 and the system manager 60 to extract inconsistent book state data. In step ST2, when there is the extracted inconsistent book status data, the system manager 60 creates (lists up) a list of unknown candidate books based on the inconsistent book status data.

  Here, as one method, a list file of unknown candidate books may be transmitted to the station terminal 61, and the station terminal 61 may display a list of unknown candidate books on the monitor 20. In this way, the library state data of the library system 63 and the automatic library system 1 are collated to extract inconsistent data, and a list (list-up) of unknown candidate books is created based on the extracted inconsistent book state data. Thus, it is possible to notify the worker M or the related person (library staff) at the cashier station 10 that there is a possibility that an unknown book has occurred.

  However, the location of the listed books is not clear simply by creating a list of unknown candidate books based on inconsistent book status data. In this form, the location of the listed books is confirmed after step ST3. An example is shown.

  As an example of the inconsistency of the book status data, when the library system 63 side is “in stock” and the system management device 60 side is “not in stock”, that is, on the data, the corresponding book 16 is not in stock in the automatic library system 1. In this case, the containers 15 that have been loaded and unloaded between the date and time of taking out the book 16 that became inconsistent in step ST3 and the date listed are listed from the data in the storage unit 70. This searches for a container 15 in which an unknown book may be stored.

  For example, if there is one unmatched in-stock data, but 20 containers 15 have been received and delivered within a predetermined period, the search range of unknown candidate books is narrowed to 20 containers. Thus, the range of unknown candidate books can be narrowed down by limiting the generation period of inconsistent inventory data within a predetermined period. The shorter the period of the listing date from the extraction date and time, the smaller the number of containers 15 that are likely to contain unknown books.

  In step ST4, the exit processing of the containers 15 narrowed down in step ST3 is performed. Here, the system manager 60 transmits an operation command (conveyance instruction) to the central control panel 62, and the central control panel 62 that has received this command controls the operations of the stacker cranes 6A and 6B and the conveying means 50 to determine a predetermined value. The container 15 that is loaded and unloaded within the period is transported to the depositing / dispensing station 10.

In step ST <b> 5, the worker M visually confirms whether there is an unknown candidate book in the container transported to the depositing / dispensing station 10. If there is a corresponding book 16, the process proceeds to step ST 6, and storage processing for the book 16 is performed. In the storing process, the IC tag of the corresponding book 16 is read by the book information reading means 21. When this reading is performed, a book storage notification is sent to the system manager 60 via the station terminal 61, and the corresponding book status data is rewritten, and the library system 63 also stores the books via the system manager 60. A notification is transmitted, and the library status data on the library system 63 side is updated.

  In step ST5, if there is no corresponding book, that is, an unknown candidate book, the process proceeds to step ST7, where it is determined whether there is another container, and if there is a corresponding container 15, the process returns to step ST4. The delivery process of the container 15 is executed. In this embodiment, since there are 20 containers 15 listed as candidates, whether or not there is an unknown candidate book in the container 15 different from the first container 15 is returned once from step ST7 to step ST4. The operator M confirms visually. If there is a corresponding book 16, storage processing is performed.

On the other hand, if there is no corresponding container 15 in step ST7, or if there is no corresponding container 15, the process proceeds to step ST8, where there is an unknown candidate book other than the automatic library system 1, that is, it is placed on the monitor 20 as that. The content of the effect is displayed and this control is finished.

  On the other hand, for example, if the inconsistency in the library status data is “not in stock” on the library system 63 side and “in stock” on the system management device 60 side, that is, on the data, the corresponding book 16 is an automatic library. If the system 1 is in stock, in step ST4, the actual book 16 is instructed to be delivered to the depositing / dispensing station, and in step ST5, it is confirmed whether or not the corresponding book 16 is stored in the container that has arrived.

  If there is a corresponding book 16 in the container, the book state data on the library system 63 side is corrected. If there is no corresponding book 16 in the container, correct the book status data on the system management machine 60 side, search for a container that may contain the corresponding book in the same way as ST3 and later, and check the corresponding book. Then, the book state data on the system manager 63 side is corrected.

Thus, the narrowed container 15 to confirm the operator M is visually if there is no unknown candidate library is unknown books generated becomes clear that not in automatic archive system 1 side, unknown books It is possible to isolate the location of occurrence and narrow the search range. In addition, the narrowed down if there is a unknown candidate books in the container 15, unknown books in the presence of unknown books that become apparent it can be seen that does not occur. Furthermore, when comparing the book status data library system 63 and the system management unit 60 as described above, since the mutual book status data during automatic archive system operation frequently transitions, operating overtime automated library system 1 It is better to perform the comparison process. It is desirable that the comparison be performed every day in order to narrow the search range. Thus, early detection and search of unknown library generation can also be in a short time, properly perform the maintenance of FIG incorporated to reduce unknown books.

Next, another embodiment of the control system will be described with reference to FIGS.
In the control system according to this embodiment, registration of the book master information stored in the system management machine 60A is not a search for an unknown book due to a mismatch between the book status data owned by the system management machine 60A and the library system 63, respectively. Search for unknown books by comparing date and time of new storage. The function of each unit shown in FIG. 8 is substantially the same as the function of each unit shown in FIG. 5, but the determination condition of the unknown book extraction process performed by the system manager 60A is not the book status data but the registration date and time of the book master information. And the new storage date and time.

  Specifically, the configuration shown in FIG. 5 is substantially the same as the configuration shown in FIG. 5 except that the storage unit 70A and the comparison unit 71A provided in the system manager 60A shown in FIG. 8 are different from the storage unit 70 and the comparison unit 71 shown in FIG. Therefore, the description of the same configuration is omitted, and the control content will be described.

  In the control system shown in FIG. 8, in the storage unit 70A, book data and book data transmitted from the library system 63 to the system management machine 60A are registered as book master information, and the book master information corresponds to the book master information. The new storage date and time D2 in which the book 16 is newly stored from the cashier station 10 is stored in the storage unit 70A. The comparison unit 71A compares the registration date and time D1 stored in the storage unit 70A with the new storage date and time D2, and if the new storage date and time D2 has not been updated within the predetermined period D3 from the registration date and time D1, within the predetermined period D3. The book 16 corresponding to the book master information that has not been updated is extracted as an unknown candidate book and listed as a list, and the container 15 in which the corresponding book may be stored is also searched for as a list. Has a function to list. The predetermined period D3 may be set in advance in the storage unit 70A, or may be changed as appropriate using the keyboard 25 or the like as setting means.

  In the automatic library system 1, the unknown candidate book extraction process shown in the flowchart of FIG. 9 is executed by the system manager 60A.

  In FIG. 9, in step ST11, the registration date D1 and the new storage date D2 stored in the storage unit 70A are read. In step ST12, it is determined whether or not the new storage date D2 has been updated within the predetermined period D3 from the registration date D1. Here, when the new storage date and time D2 is updated within the predetermined period D3, it is assumed that proper book management is performed, and this control is finished. If it is not updated within D3 within the predetermined period, it is determined that the book 16 is not updated properly. In step ST13, a list of unknown candidate books is created (listed up) using the book master information that has not been updated in the predetermined period D3, and a file is output.

  In step ST14, the list file of unknown candidate books is transmitted to the station terminal 61, and the station terminal 61 displays a list of unknown candidate books on the monitor 20. As described above, the new storage date / time D2 and the registration date / time D1 of the book master information of the automatic archive system 1 are collated with reference to the predetermined period D3 to extract the nonconforming data, and based on the extracted inconsistent book master information. Since a list file (list-up) of unknown candidate books is created, it is possible to notify the worker M or the like at the cashier station 10 that an unknown book has occurred.

Because it extracts the unknown candidate books by comparison with the registration date and time D1 and the new storage date and time D2, still or even before the new store in the middle of a book transfer work to the automatic archive system 1, initially in the automatic archive system 1 shelved whether or not but a had been planned, it is conceivable if the Shelf location may become to the change in non-automatic archive system 1, step ST15 or later is actually a load presence in unknown candidate books automatic archive system 1 How to check

  In step ST15, the list of unknown candidate books displayed on the monitor 20, that is, the unknown candidate books from the container 15 in which the unknown candidate books extracted based on the search result may be stored, that is, the registration date D1. The unloading process of the container 15 having the loading / unloading history is performed until the extraction processing date. Here, the system controller 60A transmits an operation command (conveyance instruction) to the central control panel 62, and the central control panel 62 that has received this instruction controls the operations of the stacker cranes 6A and 6B and the conveying means 50 to register them. The container 15 received / extracted from the date / time D1 to the unknown candidate book extraction processing date is transported to the depositing / dispensing station 10.

In step ST <b> 16, the worker M visually confirms whether or not there is an unknown candidate book in the container transported to the depositing / dispensing station 10. If there is a corresponding book 16, the process proceeds to step ST <b> 17, and storage processing for the book 16 is performed. In storage processing, reads the IC tag of the corresponding book 16 in library information reading means 21. When this reading is performed, the read book data of the book 16 is sent to the system manager 60A via the station terminal 61, and the corresponding new storage date and time D2 stored in the storage unit 70A is updated.

  In step ST16, if there is no corresponding book, that is, an unknown candidate book, the process proceeds to step ST18, where it is determined whether there is another container to be investigated, and if there is a corresponding container 15, Returning to ST15, the delivery process of the container 15 is executed.

On the other hand, if there is no corresponding container 15 in step ST18, or if all the corresponding containers have been investigated, the process proceeds to step ST19, where unknown candidate books are located in places other than the automatic library system 1, that is, they are distributed. As a result, the monitor 20 displays the content to that effect and ends this control.

Shelved Thus, unknown candidate library extraction operator M a narrowed container 15 by treatment confirmed visually, unknown books that occurred in the absence unknown candidate library is in a location other than the automatic archive system 1 it is it becomes clear that, can be narrowed more the range in which to line example probe isolate the unknown books occurrence location.

Next, another embodiment of the control system will be described with reference to FIGS.
In the control system according to the present embodiment, the book retrieval date and time T1 when the book 16 was taken out at the depositing / dispensing station 10 instead of searching for an unknown book due to a mismatch between the book status data owned by the system manager 60B and the library system 63, respectively. Is compared with the book storage date / time T2 at which the book 16 is stored in the depositing / dispensing station 10, and the book extraction date / time T1 is newer than the book storage date / time T2, and the book storage date / time T2 is within the predetermined time T3 from the book extraction date / time T1. The book 16 corresponding to the book master information that has not been updated is set as an unknown book.

  The function of each part shown in FIG. 10 is substantially the same as the function of each part shown in FIG. 5, but the determination condition of the unknown book extraction process performed by the system manager 60B is not the book state data but the book extraction date and time T1 and the book. The difference is that the storage date is T2.

  More specifically, the configuration shown in FIG. 5 is substantially the same as the configuration shown in FIG. 5 except that the storage unit 70B and the comparison unit 71B provided in the system manager 60B shown in FIG. 10 are different from the storage unit 70 and the comparison unit 71 shown in FIG. Therefore, the description of the same configuration is omitted, and the control content will be described.

  In the control system shown in FIG. 10, in the storage unit 70B, every time the book 16 is taken out at the depositing / dispensing station 10, the book take-out date / time T1 is updated and the book take-out date / time T1 is stored. Similarly, each time the book 16 is stored in the depositing / dispensing station 10, the book storage date / time T2 is updated and the book storage time T2 is stored.

  The comparison unit 71B compares the book take-out date / time T1 stored in the storage unit 70B with the book storage time T2. As a result of the comparison by the comparison means 71B, the system manager 60B determines that the book extraction date / time T1 is newer than the book storage date / time T2 and the book storage date / time T2 has not been updated within the predetermined time Т3 from the book extraction date / time T1. A book 16 corresponding to the information is extracted as an unknown candidate book and listed as a list, and the container 15 that may store the corresponding book 16 is also searched and listed as a list. ing. The predetermined time T3 may be set in the storage unit 70B in advance, or may be changed as appropriate using the keyboard 25 or the like as setting means.

  In the automatic library system 1, the unknown book extraction process shown in the flowchart of FIG. 11 is executed by the system manager 60B.

  In FIG. 11, in step ST21, the book extraction date / time T1 and the book storage date / time T2 of the book master information stored in the storage unit 70B are read. In step ST22, it is determined whether or not the book retrieval date and time T1 is newer than the book storage date and time T2, and whether or not the book storage date and time T2 is updated within a predetermined time T3 from the book retrieval date and time T1. . If it is updated within T3 within a predetermined time, this control is terminated assuming that proper book management is performed. If the book take-out date / time T1 has not been updated within the predetermined time T3, it is determined that the book 16 has not been updated properly. In step ST23, the book 16 corresponding to the book master information of the book extraction date and time T1 that has not been updated at the predetermined time T3 is extracted as an unknown candidate book and listed as a list.

  In step ST24, the list file of unknown candidate books is transmitted to the station terminal 61, and the station terminal 61 displays a list of unknown candidate books on the monitor 20. As described above, the book storage date and time T2 and the book retrieval date and time T1 of the book master information of the automatic library system 1 are collated with reference to the predetermined time T3 to extract nonconforming data, and based on the extracted nonconforming book master information. By creating a list file (list-up) of unknown candidate books, it is possible to notify the worker M and the like at the cashier station 10 that an unknown book has occurred.

  In step ST25, a list of unknown candidate books displayed on the monitor 20, that is, a delivery process of the container 15 in which the unknown candidate books extracted based on the search result may be stored is performed. Here, the system management machine 60B transmits an operation command (conveyance instruction) to the central control panel 62, and the central control panel 62 that has received this command controls the operations of the stacker cranes 6A and 6B and the conveying means 50, and performs a predetermined operation. The container 15 that is loaded and unloaded within the period is transported to the depositing / dispensing station 10.

In step ST <b> 26, the worker M checks whether there is an unknown candidate book in the container transported to the depositing / dispensing station 10. If there is a corresponding book 16, the process proceeds to step ST <b> 27, and storage processing for the book 16 is performed. In storage processing, reads the IC tag of the corresponding book 16 in library information reading means 21. When this reading is performed, the read book data of the book 16 is sent to the system manager 60B via the station terminal 61, and the corresponding book storage date and time T2 stored in the storage unit 70B is updated.

  In step ST26, if there is no corresponding book, that is, an unknown candidate book, the process proceeds to step ST28 to determine whether there is another container to be investigated. Returning to ST25, the delivery process of the container 15 is executed.

On the other hand, when there is no container 15 corresponding in step ST28, or when the run out proceeds to step ST29, it is unknown candidate library in a location other than the automatic library system 1, i.e. as being shelved, monitor 20 The contents of that fact are displayed on the screen and this control is finished.

  Thus, when the operator M confirms the narrowed container 15 and there is no unknown candidate book, it becomes clear that the generated unknown book is not on the automatic library system 1 side, and the occurrence of the unknown book occurs. The location can be divided and the search range can be narrowed. Further, when there is an unknown candidate book in the narrowed container 15, it is clear that the unknown book has not been generated because the existence of the unknown book has been clarified. Therefore, early detection and retrieval of unknown books can be made in a short time, the number of unknown books can be reduced, and book maintenance can be appropriately performed.

  The operation of the automatic archive system 1 is automatically performed at a preset time for power-on / off processing of each control unit. For this reason, when the operation of the automatic archive system 1 is finished, the control processing content by the control unit is set to be automatically executed, and when each processing unit is shut down when the processing is finished, the next day will be in charge. It is possible for a person to immediately investigate the listed containers. In this case, the control process to be executed in each form is performed up to the delivery process of the corresponding container 15 based on the detection result. That is, the control process shown in FIG. 7 is executed until step ST3, the control process shown in FIG. 9 is executed until step ST14, the control process shown in FIG. One day is set as the predetermined number of days. 7, 9, and 11, these processes are the same as the delivery process of the container 15, but the process from step ST <b> 1 to step ST <b> 3 in FIG. 7, the process from step ST <b> 11 to step ST <b> 14 in FIG. 9. The processing from step ST21 to step ST24 in FIG. 11 may be performed as an individual processing flow. This predetermined interval can be arbitrarily set by setting means such as the keyboard 25.

  In each of the above forms, not only a list of unknown candidate books as extraction results is displayed on the monitor 20, but also mail may be automatically delivered to the person in charge. In this case, it is also possible to notify only when an item matching the condition is extracted. In addition, it is preferable to set the execution frequency of the process in the shortest possible time so that the later search does not take time. Therefore, it is desirable to execute the unknown candidate book extraction process by each control unit, for example, every day.

  In each of the above forms, a list of unknown candidate books (list-up) is created in advance, and the container entry / exit history is searched later on the basis of this list. You may do it.

  In the actual operation, when the sensor 27 for forgetting to read the book ID shown in FIG. 4 is connected to the station terminal 61 at the opening of the depositing / dispensing station 10 as shown in JP-A-2002-338011, The sensor 27 may be activated and an error may be displayed on the station terminal 61. In this case, the station terminal 61 can be used to assist the extraction of the container 15 that has a high possibility of storing unknown books by providing a function of storing all of these error logs.

  The possibility that an unknown book is stored in a container 15 in which an error has occurred is higher than that in a container 15 in which no other error has occurred, so that the priority when actually searching for an unknown book is increased. To. For example, when searching for the container 15 based on the list of unknown candidate books (list-up) in step ST3 of FIG. 7, whether or not there is an error is added to the determination condition, and further from the searched container 15 By making the container 15 with the error occurrence history to be delivered with the highest priority, it becomes possible to retrieve an unknown book earlier.
