Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic library system used for storing various materials produced in a research and development process or a designing and manufacturing process in, for example, a laboratory or a factory. The present invention relates to a security check method for ensuring the safety of loading / unloading.

[0002]

2. Description of the Related Art Generally, in a research institute or factory of a company, various materials such as plans, specifications, and design drawings are prepared in the research and development process and the design and manufacturing process. These materials are
Since many of them usually correspond to trade secrets, it is necessary to prevent them from being taken out easily. On the other hand, it is also important that related technicians in the company can easily browse the above-mentioned materials as needed so that they can be effectively used for improvement and development of new products.

Therefore, recently, for example, when a new material is created, a person in charge of management issues a number to enter predetermined management information such as a material name in a management ledger, and then uses the material on an optical disk or the like. If you want to store it in the electronic file device that you used to store it, and when you leave this stored material,
A system in which the requester creates a slip that describes all management information such as the material number, material name, and storage address, submits it to the management staff, and the management staff issues the relevant materials based on this slip. Is being considered.

[0004]

However, in such a conventionally conceived system, the management person artificially carries out the work of storing the material and the subsequent work of leaving the material. For this reason, it is difficult to efficiently store and manage a huge amount of materials, and in particular, it takes a lot of time and labor to put and take out the materials. In addition, as for checking for storage requests, it is not always possible to perform reliable checks because it relies on the administrator's memory and verification by hand, which makes it difficult to secure a high degree of safety. It was

The present invention has been made in view of the above circumstances, and the purpose thereof is to make it possible to always perform a reliable check for a request for entry and exit, thereby ensuring a high degree of safety of stored materials. It is to provide a security check method of an electronic library system that can perform.

Another object of the present invention is to provide a security check method for an electronic library system which enables not only the requester but also the approver to check it, thereby further enhancing the reliability of the security check. Is to provide.

Still another object of the present invention is to provide a security check method for an electronic drawing system in which the approval of an approver is unnecessary depending on the form of entry and exit, and desired materials can be entered and exited easily and quickly. Is to provide.

[0008]

In order to achieve the above object, the present invention provides identification information input means to a terminal device selected from a plurality of terminal devices, and by this means, a person involved in entering / leaving a request form. The identification information of is written and the request is transferred to the library management device. Further, the library management device is provided with personnel information storage means for storing the identification information of the parties concerned, and the identification information written in the request form transferred from the terminal device is used as the identification information stored in the personnel information storage means. Collate,
The collation result is written in the request form and returned to the requesting terminal device, and the requesting terminal device determines approval or disapproval based on the collation result written in the returned request form, and if approved. Only the above-mentioned request form is transferred to the library device to request the material loading / unloading process.

Further, in order to achieve the above-mentioned other object, the present invention writes the identification information of the requester himself and the identification information of the approver such as the superior as the identification information of the parties concerned. In the library management device, the identification information of the requester and the approver entered in the request form is collated with personnel information, and the information indicating the result is written in the request form and returned to the requesting terminal device, The requesting terminal device is also characterized in that only when both the requester and the approver are approved from the above collation result, the request form is transferred to the library device to request the material loading / unloading process. To do.

In order to achieve the above-mentioned another object, the present invention determines whether or not a predetermined receipt / delivery form is designated in a request form sent from a terminal device in a library management device, When it is determined that the loading / unloading form is designated, only the identification information of the requester written in the request form is collated with the identification information stored in the personnel information storage means, and the information indicating the collation result is obtained. It is also characterized in that the request form is written and returned to the requesting terminal device.

[0011]

As a result, according to the present invention, the identification information of the persons concerned is entered in the entry / exit request form, and when entering / exiting the material,
The entry / exit request form is first sent from the terminal device to the library management device, where the identification information of the concerned person entered in the request form is collated with personnel information and then returned to the terminal device. It is determined from the above collation result whether the person concerned is approved, and only when the person concerned is approved, the library device can be accessed by the request form. For this reason, a predetermined request form must be used to access the library, and the request must be filled in with the identification information of the person concerned and checked by the library management system. It will be. Therefore, for example, it becomes impossible even if a third party other than the concerned person tries to store and retrieve the material, and thus the safety in storage of the material is secured. Further, since the identification information is always checked by the library management device, a quick and reliable check can be performed as compared with the case of relying on the memory of the person in charge of management or the collation by hand.
Furthermore, since the library device can be accessed only after the library management device has checked the request document, the library device is never accessed by an incomplete request document. It is possible to improve the operational efficiency of the system by eliminating unnecessary access to the device.

Further, according to the present invention, the security check is carried out not only for the client himself but also for the approver such as the superior, so that even an employee can enter the data without the approval of the superior. You will not be able to issue the goods. Therefore, the reliability of the security check can be further enhanced.

Further, according to the present invention, depending on the form of loading and unloading, the material can be loaded and unloaded without approval by the approver. Therefore, for example, the creator himself / herself does not intend to modify the stored material. If there is no problem in the security check, such as in the case of diverting the data, it is possible to easily and quickly issue the materials without the need for approval.

Created. Then, these created files and materials are respectively attached with file names and material numbers, and then accumulated in a buffer in the corresponding CAD tool. Note that the above-mentioned created materials and files are printed out and stored in the CMT 82 by the function of the CAD tool. (2) Preparation for enrollment of materials (collection of materials)

When the preparation of the materials to be enrolled is completed, preparation for enrollment of the materials is subsequently performed. That is, the creator first operates the keyboard to select the material to be registered, as shown in 9B of FIG. This selection is made by inputting the creation tool name, the document number, and the file name to be assembled. When the material is selected in this way, the processing of collecting the material is performed next. In this gathering process, each of the selected files is read from the CAD tool and gathered and stored in the material storage unit 325 under the subdirectory having the material number as its name. In addition, at this time, the enrollment material preparation unit 32 converts the form of the file created by the CAD tool from vector data to raster data suitable for printout, and the raster data and the original vector data are paired. It is stored in the material storage unit 325. Then, the collected materials are read from the material storage unit 325 by the material output unit 327 as shown in 9C of FIG. 9, printed out by the printer 81, and stored in the CMT 82. (3) Preparation of receipt request form

The warehousing request form is created by the first terminal devices 4a to 4m equipped with the warehousing request creating part 43. Figure 10
10A is a flowchart showing the procedure. That is, the client first uses the first terminal device (LT for client) that can be used by himself / herself to display the format of the receipt request form on the display. This format is stored in advance in the ROM in the client LT, and is read out from the ROM and displayed by selecting the menu. The client then operates the keyboard to enter the necessary information. The necessary items include, for example, the material name, the creator (requester) section name, and the requester name. The created receipt request form is stored in a floppy disk (FD) 7, which is a portable external storage medium. (4) Approval of request form and clear copy

The requester submits the FD 7 in which the created receipt request form is stored to the superior for approval of entry. On the other hand, the superior uses the first terminal device (LT for superior) having the entry / exit request approval unit 44 to perform the approval and the clean copy operation. 10B and 10C of FIG. 10 are flowcharts showing the procedure. In the figure, when the FD 7 is set in the superior terminal device, the warehousing request form stored in the FD 7 is read by the warehousing / leaving request approval unit 44 and displayed on the display. In this state, if the superior inputs his employee code, for example, this employee code is written in the approval column in the request form. And
When the superior performs a clean book activation operation, the transmitter / receiver 45 transmits the approved request to the library management device 2 via the loop transmission network 6.

In the library management device 2, when a request form arrives from the terminal device, a ledger search process is executed as shown in 10D of FIG. That is, first, in the security check unit 233, the requester name of the request form and the employee code of the approver are inquired into the personal information ledger 22, respectively, and it is determined whether the corresponding employee or approver is qualified. Then, if the person is qualified, the warehousing request in which the fact is entered is returned to the requesting superior LT. At this time, the name of the approver is newly written in the approval column of the return request form. On the other hand, if the qualification is not recognized by either the employee or the approver, the information to that effect is notified to the requesting superior's LT.

In the terminal device, when the request form is returned from the library management device 2, the content is displayed on the display and written in the FD 7. The superior returns the FD 7 storing the approved request form to the requester. (5) Enrollment Processing Enrollment processing is performed as follows using the client's terminal device (EWS). FIG. 11 schematically shows the procedure. (a) Input of receipt request form

When the client sets the FD7 returned from the superior in the terminal device (EWS), the approved storage request file stored in this FD7 is processed in the processing block 11.
In A, it is read into the entry / exit request entry input unit 3331 and held in the entry / exit request entry holding unit 334. The read-in receipt request form is displayed on the display, and the requester can change the contents as necessary in this state. At this time, the employee code of the approver is not displayed in the approval column of the displayed request form, but the approver name is displayed. Therefore, there is no fear that the employee code of the approver is known to the requester. (b) Input of material data for enrollment

Next, the enrollment material holding unit 331 of the terminal device performs the enrollment material data reading process as shown in processing block 11B. That is, the registration material preparation section 3
When the material data held in No. 2 is to be enrolled, the corresponding material data is read from the material storage unit 325 of the enrollment material preparation unit 32 and input to the enrollment material work 3331. Also, when enrolling handwritten materials etc.,
This handwritten material is read and scanned by the image reader (scanner) 9 and input to the enrollment material work 3331 as image data. (c) Clear copy processing for ledger search

When the entry material data has been input in this way, the terminal device next performs a clearing process on the previously read approved receipt request form in processing block 11C. That is, the terminal device is the ledger inquiry processing unit 3 of the warehousing processing unit 335.
First, the library management device 2 is accessed by 351 to read the approved request form from the entry / exit request document holding unit 334 and transmit it to the library management device 2. Then, in the library management device 2, first, in the processing block 11D, a security check is performed on the requester and the approver of the storage request form. This security check is performed by referring to the personal information ledger for the employee code of the requester and the approver entered in the receipt request form.
When the qualifications of the requester and the approver are confirmed by this check, the material management ledger storage unit 21 is accessed and the number of material data to be entered into the material management ledger is registered. Then, the receipt request form in which the library device number of the entry destination designated by the ledger search processing unit 234 and the result of the security check are entered is edited and returned to the terminal device.

FIG. 12 is a flow chart showing a communication procedure between the terminal device (EWS) and the library management device 2 when performing the above-mentioned fair copy processing. The terminal device first converts the format of the request form into an electronic slip file for transmission and then transmits it to the library management device 2, and subsequently transmits a processing request message. On the other hand, the library management device 2 accumulates the electronic slip file, and when receiving the processing request message, issues a reception number and notifies the terminal device. Then, according to the contents of the electronic slip file, the above-described ledger search processing, that is, the security check, the material ledger search, and the search result editing processing are executed. Upon receiving the receipt number, the terminal device periodically and repeatedly transmits a processing status search message. The drawing management device 2 checks the processing status and notifies the terminal device every time the processing status search message is received. When the terminal device confirms that the processing is completed based on the notification contents of the processing status, the terminal device transmits a processing result confirmation message to the library management device 2. On the other hand, the library management device 2
Receives the processing result confirmation message, notifies the terminal device of the processing result, and then transmits the electronic slip file of the edited request form to the terminal device. Upon receiving the electronic slip file, the terminal device temporarily stores the file, converts the file into the format of the request form, stores it in the entry / exit request document holding unit 334, and ends the series of communication procedures associated with the clean copy. (d) Enrollment

When the clearing process of the receipt request form is completed in this way, the receipt processing unit 335 of the terminal device executes the entry process shown in the processing block 11E of FIG. The shelf management process shown in 11F is executed. That is, this shelf management process
Resource management processing, shelf status management processing, receipt request file transfer processing, material data file transfer processing for registration, shelf processing start request processing, shelf management for registration, shelf processing completion monitoring processing, request file transfer processing and request The write file deletion process is executed in the order. FIG. 13 shows the processing sequence.

First, in the resource management process, the terminal device accesses the bookkeeping device of the enrollment destination based on the content of the above-mentioned entry request form, and transfers the file name and size of the enrollment material to this booklet device. Then, in the library device, the remaining amount of the magnetic disk and the duplication of the file name are checked, and an area corresponding to the size of the enrollment material file is secured.

In the shelf status management processing, the status check in the library computer is performed in the library device in response to the activation of the shelf status management from the terminal device. The check contents include a registration system shelf management process activated state, a registration system process prohibited state, a terminal request process acceptance prohibited state, an optical disk shelf maintenance, a magnetic disk shelf maintenance, and a hardware status. These check results are notified from the library device to the terminal device.

Next, in the receipt request file transfer process,
The file transfer preparation function of the library device is activated by the terminal device, and the transfer command is issued by the terminal device in this state, and the receipt request form is transferred from the terminal device to the library device together with this transfer command. The transferred receipt request form is accumulated in the request form buffer 142. After the transfer is completed, the file transfer end function notifies the terminal device that the file transfer is completed. When the transfer command is issued, the file name on the shelf side is set to “request form file name” + “terminal host ID”.

In the transfer target material data file transfer process, the file transfer preparation function of the library is activated by the terminal device, and the transfer command is issued by the terminal device. At that time, the directory name on the shelf side is "material number" +
It is set to "terminal host ID". The enrollment material data file is read from the enrollment material work 331 in the terminal device, and together with the transfer command, the enrollment execution unit 335.
3 is transferred to the library device. The transferred material data file is stored in the material buffer 144. After the transfer is completed, the file transfer end function notifies the terminal device that the file transfer is completed.

Subsequently, in the shelf processing start request function processing, a processing request for executing the entry shelf processing of the previously transferred material data file is transferred from the terminal device to the library device. The processing request is made, for example, by registering the request file name in the enrollment processing waiting queue, which is one of the processing operation states of the library device. When the registration waiting queue registration by the processing request is completed, the library device notifies the terminal device of the registration completion status.

Now, the entry shelf management process is carried out as follows. FIG. 14 is a flowchart showing the procedure. That is, if the enrollment processing unit 145 of the library device determines that enrollment processing is possible in step 14a, step 14
In b, the request file name is fetched from the enrollment processing waiting queue, and in step 14c, one request data is fetched from this request file. Then, when it is determined in step 14d that the enrollment process is possible, the shelf status file is set in the enrollment process in step 14e, and then step 1
Write the material data to the optical disk shelf 12 by 4f,
Further, in step 14g, the same material data is written on the magnetic disk shelf 11. Then, in step 14h, the shelf status file is returned to unregistered. That is, the enrollment material data is stored not only on the optical disk shelf 12 but also on the magnetic disk shelf 11 at the same time.

When the writing of the material data is completed in this way, the library device then executes the request file accumulation process in step 14i. In this storage processing, the storage request form file in which the materials have been registered is stored in, for example, the management area in the magnetic disk shelf 11. At that time, the processing result (status) in the shelf access processing such as the processing date is added to the request file in step 14j. Further, the request form file is stored, for example, on a monthly basis. Further, data indicating the storage position of the enrollment material is registered in the shelf management table 13. The data representing the storage position includes material table of contents data and material table of contents list data.

When all the storage processing of this request file is completed, the library device finally registers the end status in the enrollment completion queue in step 14k, and then returns to step 14a and shifts to the processing for the next request file. To do.

In the shelf processing completion monitoring function processing, the state of the enrollment completion queue is monitored in the library device, and when the processing completion status is registered in the enrollment completion queue, this processing completion status is notified to the terminal device.

The request file transfer process is performed by the terminal device issuing a transfer command and sending this transfer command to the library device. That is, when the transfer command is sent, the library device reads out the request file with the processing result (status) from the request buffer 142 and transfers it to the terminal device. The terminal device stores the request document file transferred from the library device into the storage request document storage unit 3
34. The file name on the shelf side when issuing the above transfer command is "request form file name" +
"Terminal host ID" is designated.

Finally, the request form file deleting process is a process for deleting unnecessary material data groups and request form files remaining in the transmission / reception work area of the library device after the enrollment process is completed according to the instruction of the terminal device. That is, when it is confirmed that the request form file has been transferred from the library device, it is activated in the terminal device. That is, when the terminal device confirms the transfer of the request file from the library device, it issues a file deletion command and sends it to the library device. Then, the library device erases the corresponding unnecessary file remaining on the transmission / reception work area, and when the erasing ends, notifies the terminal device of the erasing end status. Upon confirming the notification of the status, the terminal device ends the series of enrollment processing. (e) Clean copy processing for updating the ledger

When the enrollment process of the material data file is completed, the terminal device next executes a clear copy process in processing block 11G. That is, the terminal device first accesses the library management device 2 by the ledger update processing unit 3352 of the inventory processing unit 335 and reads the request form transferred from the library device after the enrollment process from the entry / exit request document holding unit 334. And sends it to the library management device 2. In the library management device 2, processing block 1
In 1H, first, a security check is performed on the requester and approver of the request form. If this check is passed, the material management ledger storage unit 21 is accessed and the corresponding management information item in the material management ledger is updated based on the content of the request form. The management items to be updated include, for example, the registration date and the size of the material. When this update processing is completed, the processing result and the result of the security check are edited and returned to the terminal device. Upon receiving the edited result by the ledger update processing unit 3352, the terminal device stores the edited result in the entry / exit request holding unit 334. (f) Output of receipt request form

The terminal device is provided with the storage / receipt request document holding unit 33.
The corresponding receipt request file is read from No. 4, and this receipt request file is stored in the storage medium of the input source. For example, when the storage medium of the input source is the floppy disk 7, the mount of the FD 7 is confirmed, and a predetermined code conversion and file format conversion are performed to perform F conversion.
After converting to a signal form suitable for D7, it is written in FD7. When the storage medium of the input source is the hard disk 7 built in the terminal device, the above-mentioned storage request form file is directly written to this hard disk. (6) Shelf management after joining

The storage capacity of the magnetic disk shelf 11 is smaller than that of the optical disk shelf 12 and is fixed. Therefore, when the storage amount of the enrollment material data reaches the maximum storage capacity of the magnetic disk shelf 11, it becomes impossible to store the material data in the magnetic disk shelf 11 thereafter. Therefore, in the library apparatus of the present embodiment, when the amount of enrollment material data accumulated reaches the maximum storage capacity of the magnetic disk shelf 11, thereafter, each time new enrollment material is transferred from the terminal device, the magnetic disk shelf 11 is transferred. The oldest material data among the material data stored in 11 is deleted, and the new enrollment material data is stored instead. In this case, even if the old material data is erased from the magnetic disk shelf 11, since the material data is still stored in the optical disk shelf 12, there is no concern that the material data will be completely deleted from the library device. That is, all the registered material data are stored in the optical disk shelf, and only a predetermined amount of material data having a new registration timing is stored in the magnetic disk shelf 11.

The reason why the relatively new material data registered is stored in the magnetic disk shelf 11 together with the optical disk shelf 12 is as follows. That is,
Regarding the number of material data to be paid out in an operation such as “drawing”, which will be described later, the new material is usually overwhelmingly larger than the old material. Further, generally, the access required time for paying out the stored material data is shorter for the magnetic disk than for the optical disk.
Therefore, by storing the material data for which the registration is relatively new in the magnetic disk shelf 11 as described above, the relatively new material data with a high payout frequency can be paid out in a shorter time than the magnetic disk shelf 11. Can realize a system with high access speed. B. "Outgoing drawing" (1) Creation of shipping request form "Outgoing drawing" is an operation to take out the materials already registered in the drawing storage devices 1a to 1d, so there is no need to create the materials and Start with creating.

The delivery request form is created using the first terminal devices (LT) 4a to 4m provided with the delivery request form creating unit 43, similarly to the above-mentioned delivery request form. FIG. 15 is a flowchart showing the schematic procedure.

In the figure, first, in processing block 15A, the material management ledger of the library management apparatus 2 is searched to obtain the management information of the material data to be output. That is, the basic format of the search request form is read from the search request form holding unit 42 and the material ledger search unit 41 is read.
To be displayed on the display. In this state, when the client inputs his / her employee code and department / section code and then the number of the material data to be printed, the transmitter / receiver 45 accesses the library management device 2 and the above search request form. Is transmitted to the library management device 2.

Then, in the library management apparatus 2, the processing of searching the material management ledger is performed in the processing block 15B according to the contents of the search request form. That is, first, in the security check unit 233, the employee code and department code of the client are inquired into the personal information ledger 22, and it is checked whether or not the person is qualified to search.
If it is determined that there is a search qualification, the ledger search processing unit 234
Then, the material management ledger 21 is accessed, and the management information corresponding to the material data number described in the search request form is retrieved. The retrieved management information includes the type and size of the material, the file name, and the like, as well as the identification information of the library device in which the material data is stored. Then, these management information is written in the search request together with the result of the security check, and then returned to the requesting terminal device.

When the retrieval request form is returned from the library management device 2, the terminal device next creates a delivery request form by the processing block 15C. That is, in the entry / exit request document creating unit 43, first, the management information of the search request document sent from the library management device 2 is transferred to the basic format of the exit request document. In this state, the client key-inputs other information as needed. The information input at this time includes, for example, information designating whether or not it is an emergency drawing. Then, when the preparation of the delivery request form is completed, this delivery request form is written in the FD 7. (2) Approval of request form and clear copy

The requester submits the FD 7 in which the created delivery request form is stored to the superior in order to receive approval for drawing out. On the other hand, the superior uses the first terminal device (LT for superior) having the entry / exit request approval unit 44 to perform the approval and the clean copy operation. Processing blocks 15D and 15 of FIG.
E indicates the processing contents in the entry / exit request approval unit 44 of the senior manager LT. That is, first, in the processing block 15D, the delivery request form stored in the FD 7 is read by the entry / exit request delivery approval unit 44 and displayed on the display. In this state, if the superior inputs his employee code, for example, this employee code is written in the approval column in the request form. Then, when the superior performs a clean copy start operation, the approved request form is transmitted from the transmission / reception unit 45 to the loop transmission network 6 by the processing block 15E.
It is transmitted to the library management device 2 via.

In the library management apparatus 2, when a delivery request form arrives from the superior manager LT, the ledger retrieval process is performed by the processing block 15F. That is, first, in the security check unit 233, the employee code and department code of the requester and the employee code of the approver described in the above-mentioned delivery request form are respectively inquired into the personal information ledger 22, and the corresponding employee and It is judged whether the approver is qualified. Then, if the person is qualified, a request form informing that fact is returned to the requesting terminal device. At this time, the name of the approver is newly written in the approval column of the return request form. On the other hand, if the qualification is not recognized by either the employee or the approver, the information to that effect is notified to the requesting superior's LT.

In the superior manager LT, when the goods issue request form is returned from the library management device 2, the contents are displayed on the display and written in the FD 7. The superior returns the FD 7 storing the approved delivery request form to the requester. (3) Drawing process The drawing process is performed as follows using the terminal device (EWS) of the client. FIG. 16 schematically shows the procedure. (a) Entering the goods issue request form

When the client sets the FD7 returned from the superior in the terminal device (EWS), the approved delivery request file stored in this FD7 is processed in the processing block 16
In A, it is read into the entry / exit request entry input unit 3331 and held in the entry / exit request entry holding unit 334. The read-out delivery request form is displayed on the display, and the requester can change the contents in this state as necessary.
At this time, the employee code of the approver is not displayed in the approval column of the displayed request form, but the approver name is displayed. Therefore, there is no fear that the employee code of the approver is known to the requester. (b) Clear copy processing for ledger search

Next, in a processing block 11C, a clearing process of the approved delivery request form is performed. That is,
The terminal device (EWS) first accesses the library management device 2 by the ledger inquiry processing unit 3351 of the warehousing processing unit 335, and stores the above-mentioned approved warehousing request form into the warehousing and issuing request holding unit 33.
It is read out from the No. 4 and transmitted to the library management device 2.

Then, in the library management apparatus 2, the security check is first performed on the requester and the approver of the delivery request form in the processing block 16C. This security check is performed by referring to the personal information ledger 22 for the employee code of the requester and the approver entered in the delivery request form. When the qualifications of the requester and the approver are confirmed by this check, the material management ledger 21 is accessed by the ledger search processing unit 234, and the contents of the delivery request form are checked based on the management information registered in this ledger. Judgment of correctness and supplementation of contents are performed. When the completed delivery request form is obtained, the delivery request form is added with the result of the security check and is then returned to the requesting terminal device (EWS).
It should be noted that the terminal device (EWS) for performing the above-mentioned fair copy processing
The communication procedure between the and the library management device 2 is substantially the same as the procedure described with reference to FIG. 12 in the enrollment process. (c) Disbursement processing

When the clearing process of the delivery request form is completed in this way, the delivery processing unit 336 of the terminal device (EWS) displays in FIG.
The payout process shown in the process block 16D is executed, and in response to the payout process, the shelf management process shown in the process block 16E is executed in the library apparatus. That is, this shelf management processing includes resource management processing, shelf status management processing, delivery request file transfer processing, shelf processing start request processing, shelf management for delivery, shelf processing completion monitoring processing, material file transfer processing, material files. The deletion process, the request form file transfer process, and the request form file deletion process are executed in this order. FIG. 17 shows the processing sequence.

First, in the resource management processing, the terminal device accesses the drawing device based on the contents of the above-mentioned delivery request form, and transfers the file name and size of the payout material to this drawing device. Then, in the library, the remaining amount of the work area of the magnetic disk 11 and the duplication check of the file name are checked, and an area corresponding to the size of the enrollment material file is secured.

In the shelf status management process, the status check in the library computer is performed in the library device in response to the activation of the shelf status management from the terminal device (EWS). The check contents include a payout system shelf management process activation state, a payout system process prohibition state, a terminal request process acceptance prohibition state, an optical disk shelf maintenance, a magnetic disk shelf maintenance, and a hardware state. These check results are notified from the library device to the terminal device.

Next, in the delivery request file transfer process,
The file transfer preparation function of the library device is activated by the terminal device, and in this state, a transfer command is issued by the terminal device, and the delivery request form is transferred from the terminal device to the library device together with this transfer command. The transferred delivery request form is accumulated in the request form buffer 152. After the transfer is completed, the file transfer end function notifies the terminal device that the file transfer is completed. When the transfer command is issued, the file name on the shelf side is set to “request form file name” + “terminal host ID”.

Subsequently, in the shelf processing start request function processing, a processing request for executing the payout system shelf processing is transferred from the terminal device to the library device in accordance with the shipping request file previously transferred. The processing request is made, for example, by registering the request file name in the payout processing waiting queue, which is one of the processing operation states of the library apparatus. When the payout waiting queue registration by the above processing request is completed, the library device notifies the terminal device of the registration completion status.

Now, the payout shelf management process is carried out as follows. FIG. 18 is a flowchart showing the procedure. That is, when the payout processing unit 153 of the library device determines in step 18a that the payout processing is possible, the payout processing unit 153 proceeds to step 1
At 8b, the request file name is fetched from the payout process waiting queue, and at step 18c, one request data is fetched from this request file. And step 18d
If it is determined that the payout process is possible in step 18e, the shelf status file is set to the payout process in step 18e, and then the storage location of the corresponding material data file is searched based on the shelf management information in the shelf management table 13 in step 18f.
In this search of the storage location, it is determined from which material index file the material data file is stored, and from the material index data which address area in the disk is stored.

If it is determined by this determination that the relevant material data file is currently stored in the magnetic disk, the magnetic disk shelf 11 is accessed in step 18g, and the material data file is read from the corresponding address area. . On the other hand, when the material data file is stored in the optical disk shelf 12, the corresponding disk is selected by the autochanger in step 18h, and the material data file is read from the corresponding address area. The material data file read from the magnetic disk shelf 11 or the optical disk shelf 12 is temporarily stored in the material buffer 155. When the reading of the material data file is completed, the shelf status file is returned to the unprocessed state in step 18i.

When the reading of the material data is completed in this way, the library device then executes the request file accumulation process in step 18j. In this accumulation processing, the delivery request file for which the materials have been paid out is, for example, the magnetic disk 1
It is stored in the management area within 1. At that time, the processing result (status) of the shelf access processing such as the processing date is added to the request file at step 18k. Further, the request form file is stored, for example, on a monthly basis.

The stored data of the request form file is read out semi-annually or annually, for example, by the access of the terminal device, stored in the terminal device and printed out. Therefore, the person in charge of managing the system can efficiently plan an expansion plan of the library device by analyzing the accumulated data of the printed out request file.

When all the request file files have been stored, the library device finally registers the end status in the payout completion queue in step 18l, and then returns to step 18a to move to the next request file processing. To do.

In the shelf process completion monitoring function process, the state of the payout completion queue is monitored in the library device, and when the process completion status is registered in the payout completion queue, this process completion status is notified to the requesting terminal device. It

In the material file transfer process, the terminal device (E
In WS), a payout transfer command is issued, and in response to this command, the material data file is read from the material buffer 155 of the library and is transferred to the terminal device.
This transferred material data file is the payout execution unit 33.
The received material buffer 3321 received by 63.
Accumulated in. In addition, "material number" + "terminal host ID" is designated as the shelf-side directory name when the above-mentioned payout transfer command is issued.

The material file deletion process is a process for deleting the transferred material data group remaining in the transmission / reception work area of the library device after the payout process is completed, according to the instruction of the terminal device. It is started by the terminal device when the end of the transfer of the file is confirmed. That is, when the terminal device confirms the transfer of the material data file from the library device, it issues a file deletion command and sends it to the library device. Then, the library device erases the corresponding unnecessary file remaining in the transmission / reception work area, and when the erasing ends, returns the erasing end status to the terminal device.

The request file transfer process is performed by the terminal device issuing a transfer command and sending this transfer command to the library device. That is, when the transfer command is sent, the library device reads the request file with the processing result (status) from the request buffer 152 and transfers it to the terminal device. The terminal device stores the request document file transferred from the library device into the storage request document storage unit 3
34. When issuing the transfer command, “request form file name” + “terminal host ID” is designated as the file name on the shelf side.

Finally, the request file deletion process is a process for deleting an unnecessary material data group and request file remaining in the transmission / reception work area of the library device after the completion of the payout process in accordance with an instruction from the terminal device. That is, when it is confirmed that the request form file has been transferred from the library device, it is activated in the terminal device. That is, when the terminal device confirms the transfer of the request file from the library device, it issues a file deletion command and sends it to the library device. Then, the library device erases the corresponding unnecessary file remaining on the transmission / reception work area, and when the erasing ends, notifies the terminal device of the erasing end status. Upon confirming the notification of this status, the terminal device ends the series of payout processing. (d) Output processing of payout materials

When the payment of the material is completed in this manner, the terminal device subsequently causes the paid-out material output unit 3322 to execute the output processing of the paid-out material. That is, the paid-out material data is composed of a pair of vector information and raster information by the conversion process from vector information to raster information by the CAD tool described above. That is, the material data has already been converted into raster information when it was created.
Therefore, the paid-out material output unit 3322 selects raster information suitable for printout from the vector information and raster information, and outputs this raster information to the print server 8 as it is. Therefore, the paid-out material is printed out as image data by the printer 9. Therefore, the printed out material data can be printed out in a shorter time than the case where the vector information is converted into raster information and printed out at the time of output. The paid-out material data is output and stored in the CMT 5 with the material number added. (e) Output of goods issue request form

The terminal device has the above-mentioned storage / delivery request holding unit 33.
The corresponding request file is read out from No. 4, and this request file is stored in the storage medium of the input source. For example, when the storage medium of the input source is the floppy disk 7,
The mount of the FD7 is confirmed, and a predetermined code conversion and a file format conversion are performed to convert it into a signal form suitable for the FD7, and then the FD7 is written. If the storage medium of the input source is the hard disk 7 built in the terminal device, the request file is directly written to this hard disk. C. "Reuse"

The "reuse" is an operation for taking out the material data from the library device for the purpose of diverting the material data for the purpose other than the modification by the creator himself as described above. The case is the same as the case except for the following two points.

One of the differences is that in "drawing", the presence / absence and qualification of the approver are checked in the security check of the drawing management device 2, whereas in "reuse", only the requester is checked. Therefore, the check of the approver is omitted. Another difference is that, in "drawing", the material data delivered from the library to the terminal is automatically printed out by the printer 81 or written in the CMT 82, whereas "reuse" In the above, the paid-out material data is once stored in the paid-out material buffer 334, and is printed out or written in the CMT 82 only when the requester inputs an output instruction by a key in this state.

That is, when the material is paid out by "reuse", the client enters the employee code and subordinate code together with management information necessary for paying out such as the material number in the delivery request form, and Enter "use". Then, the exit request form is read as it is into the terminal device (EWS) without passing through the approver.

Then, the terminal device activates the clean copy for searching the ledger, and the bookkeeping management device 2 carries out the clear copy process accordingly. That is, when the delivery request form is transferred from the terminal device, in the library management device 2, first, the security check unit 233 determines whether or not the delivery request form requests “reuse”. And
In the case of “reuse”, the employee code and subordinate code of the requester entered in the delivery request form are inquired into the personal information ledger 22 and it is determined whether or not the person is qualified. If the request is for a request for an action other than "reuse", it will be based on the employee code and subordinate code of the requester and the employee code of the approver as in the case of "drawing". Security check is performed.

Then, as a result of the above security check, when it is determined that the requester is eligible to pay out the material for reuse, the material management ledger is searched in the ledger search processing unit 234, and this ledger is searched. Whether the contents of the delivery request form are correct or not is determined and the contents are replenished based on the registered management information. When the completed delivery request form is edited, the delivery request form is returned to the requesting terminal device (EWS) after the result of the security check is added.

When the delivery request form is returned, the terminal device (EWS) starts a process for paying out the material to the drawing device based on the contents of the delivery request form.
Thus, in the case of "reuse", it is possible to shift to the process of paying out the material without the approval of the approver, only by the security check of the client himself. Therefore, compared with the case where the superior's approval is unconditionally required, the troublesome approval work is unnecessary and the material can be immediately and easily withdrawn when necessary.

On the other hand, the paid-out material data transferred from the library device to the terminal device (EWS) is retained in the paid-out material buffer 3321 as it is even after the series of paying-out process with the library device is completed. It In this state, when the client operates the keyboard to input a printout instruction, for example, the paid-out material output unit 3322 is activated,
The material data held in the paid-out material buffer 3321 is read. Then, this material data is supplied to the printer 81 via the printer server 8 and printed out. In addition, the paid-out material data is CMT8.
In the case of storing the data in No. 2, it is similarly performed according to the input instruction of the client. D. "Borrow"

“Borrowing” is an operation for extracting the material for the purpose of modifying, that is, correcting or adding the material as described above, and the material in the borrowed state is returned until it is returned. Drawing, reuse and borrowing are prohibited. Therefore, in this "borrowing" processing sequence, after receiving the payment of the material, it is necessary to perform the ledger update processing for prohibiting the payment of the material from the terminal device to the library management device.

FIG. 19 is a flow chart showing a schematic procedure for carrying out this "borrowing". In the figure, from a processing block 19A for inputting a request form, a processing block 19 for outputting material data which has been paid out.
The processing contents up to F are the same as the processing contents of the corresponding processing blocks 16A to 16F in the case of "drawing" shown in FIG. 16, and a clear copy processing for updating the ledger after the output of the paid-out material data is completed. Is different.

That is, when the output processing of the paid-out material data by the processing block 19F is completed, the ledger update processing unit 3362 of the delivery processing unit 336 of the terminal device activates the clean copy shown in the processing block 19G. In addition, in the library management device 2, the clear copy process shown in the processing block 19H is performed in response to the clean copy activation of the terminal device. That is, in the terminal device, the ledger update processing unit 3362 of the delivery processing unit 336 first accesses the library management device 2, and the delivery request form transferred from the library device after the material is delivered is transferred from the entry / exit request document holding unit 334. It is read and transmitted to the library management device 2. In the library management apparatus 2, first, the security check of the requester and the approver of the above-mentioned delivery request form is performed. Then, when it is determined by this check that the requester and the approver are qualified persons, the ledger search processing unit 234 accesses the material management ledger storage unit 21 to store the corresponding management information in the material management ledger. Items are updated based on the contents of the delivery request form. The most important management item to be updated is the registration setting to prohibit the payment of the material. When this setting is made, even if a request for drawing, reuse and borrowing of the material is made thereafter, the operation is prohibited. When this update processing is completed, the processing result and the result of the security check are edited and notified to the requesting terminal device. In the terminal device, when the ledger update processing unit 3362 receives the edited result, the result is stored in the entry / exit request holding unit 334.

When the above series of processes relating to the clean copy is completed, the terminal block reads out the corresponding request file from the storage request document holding unit 334 in the processing block 19I, and this request file is the input source storage medium. Memorized in. For example, the storage medium of the input source is the floppy disk 7
If it is, it is written in this FD7.

By the key operation of the requester, the paid-out material data accumulated in the paid-out material buffer 3321 is transferred to a desired CAD tool of the enrollment material creation unit 31,
With this CAD tool, it is also possible to carry out an improved design or the like based on the paid-out material data. In this case, the paid-out material data is composed of the vector information and the raster information as described above, and the CAD tool selects the vector information and provides it for the improved design. Therefore, for example, as compared with the case where the material data is registered only in the state of raster information, the conversion processing from raster information to vector information becomes unnecessary, and the circuit configuration and the processing program can be simplified accordingly.

(5) "Return" means releasing the borrowed state of the borrowed material data in the library as described above, and making it possible to issue the drawing, reuse the borrowed material, and make a borrowing request. It is an operation to do. FIG. 20 is a flowchart showing the outline of the procedure.

When returning the borrowed material, the requester creates a request form for the return, and after receiving the approval of the approver, causes the terminal device (EWS) to read the approved request form. In the terminal device, when the approved request form is read in the processing block 20A, the ledger update processing unit 3362 of the goods issue processing unit 336 activates a clean copy for ledger update. Further, in response to this, the bookkeeping management device 2 carries out a clean copy process.

That is, in the terminal device, the ledger update processing unit 3362 first accesses the library management device 2, and the approved return request form is read from the entry / exit request document holding unit 334 to the library management device 2. Sent. In the library management device 2, first, the security check of the requester and the approver of the return request form is performed. Then, when it is determined by this check that the requester and the approver are qualified persons, the ledger search processing unit 234 accesses the material management ledger storage unit 21 to store the corresponding management information in the material management ledger. Items are updated based on the contents of the delivery request form. That is, the setting of the prohibition registration of paying out the material is canceled. Once this is released, the material can be subsequently released, reused and borrowed. Then, when this update processing is completed, the processing result and the result of the security check are edited and notified to the requesting terminal device. In the terminal device, when the ledger update processing unit 3362 receives the edited result, the result is stored in the entry / exit request holding unit 334.

Next, in the terminal device, the payout execution unit 3363 of the delivery processing unit 336 executes the return notification processing shown in the processing block 20D. Further, in response to this processing, the shelf management processing shown in processing block 20F is executed in the library apparatus. That is, in the terminal device, the payout executing unit 3363 accesses the corresponding library device based on the content of the above-mentioned return request document, and the above-mentioned return request document is transferred to this library operation. On the other hand, in the library device, when the above-mentioned return request form is sent, this request form is issued to the payout processing unit 1
It is stored in the resource management area of the magnetic disk 11 by 53. Then, after this accumulation, the return request form to which the information indicating the result is added is edited and returned to the requesting terminal device. When the return request form is returned from the library device, the terminal device stores the return request form in the storage and receipt request form holding unit 334.
And the return process ends.

As described above, according to the security check method of this embodiment, the following various effects can be obtained. That is, the identification information of the requester himself and the identification information of the superior who is the superior are entered in the entry / exit request form, and when entering / exiting the material, the entry / exit request form is first displayed in the terminal device (EW).
S) 3a to 3n are transferred to the library management device 2, and the identification information of the requester and the approver entered in the request form by the security check units 233 and 243 is stored in the personal information ledger storage unit 22 as personnel information. After that, it is returned to the terminal devices (EWS) 3a to 3n. Then, the terminal device determines whether or not the requester and the approver are approved based on the collation result, and only when approved, the library devices 1a to 1d are accessed by the request form. Therefore, in order to access the library devices 1a to 1d, a predetermined request form must be used, and the identification information of the requester and the approver must be entered in the request form before the library management device 2 operates. You will have to undergo the check. Therefore, for example, it becomes impossible for a third party other than the related person to store and retrieve the material, which makes it possible to maintain high safety in storage of the material.

Further, since the identification information is always checked by the library management device, a quick and reliable security check can be performed as compared with the case of relying on the memory of the person in charge of management or the collation by hand. Further, since only the request form that has undergone the security check in the library management device 2 is transferred to the library device 1a to 1d, it is possible that the library device 1a to 1d is accessed by the request document with the incomplete security check. As a result, the library device 1a
It is possible to improve the operational efficiency of the system by eliminating the unnecessary access of 1d.

In the case of "reuse", the security check of the approver is omitted so that the material can be put in and out, so that the stored material is not used by the creator himself but is diverted to another. When there is no problem in the security check as in the case of doing, it is possible to easily and quickly issue the material without the need for approval and the like.

The present invention is not limited to the above embodiment. For example, in the electronic library system of the above-described embodiment, a terminal device different from the terminal devices (EWS) 3a to 3n having a material creating function and a material entering / outgoing processing function in the function of creating a request for entering and exiting and its approval function. (LT) 4
Although all the functions are provided to a to 4 m, all the functions may be provided to the terminal devices (EWS) 3 a to 3 n. Further, only the request form approval function is provided in the other terminal devices (LT) 4a to 4m, and all other functions are provided in the terminal devices (EWS) 3a to 3n.
It may be provided in the. In this way, the load on the terminal devices (EWS) 3a to 3n increases, but for the client, the terminal devices (EWS) 3a to 3n owned by the client are used to digitize the data from the creation / modification process. This makes it even more convenient because you can consistently perform access processing for creating a delivery request form and entering and exiting. At that time, only the approval function of the request form, for example, the terminal device for the superior (L
If it is provided in T), a system more preferable in terms of security can be configured.

Further, in the above embodiment, the terminal device (LT)
Although 4a to 4m are provided with the function of creating the entry / exit request and the function of approving the entry / exit request, respectively, these functions may be provided separately to different terminal devices. That is, a terminal device (EWS) having a material creation function and a material loading / unloading processing function, a terminal device (LT) having a loading / unloading request creation function, and a terminal device (LT) having an approval function are provided. Good. By doing this, each technician owns the terminal device (EWS), and the terminal device (LT) having the function of creating the request document for loading and unloading is shared by, for example, a plurality of technicians in the same department, and the approval function is added. Only the superior can own the terminal device (LT) having the. Also, at this time, the terminal device for superiors is configured by EWS,
This terminal device (EWS) may be provided with a material creation / modification function and an entry / exit request approval processing function.

In the case of the library management device 2 of the above-mentioned embodiment, when the existence of the requester or the approver is not confirmed as a result of collating the identification codes of the requester and the approver described in the entry / exit request form. Also, request form the terminal device (EWS) 3a
3 to 3n, the terminal device (EWS) 3a to 3n may be notified of only the information indicating that the existence of the requester or the approver has not been confirmed, and the request may not be returned. . By doing so, the amount of data returned from the library management device 2 to the terminal devices (EWS) 3a to 3n can be reduced, and as a result, the terminal device (EWS) 3a.
It is possible to shorten the communication time between 3n and the library management device 2.

Further, in the above embodiment, the employee code of the approver is input and checked by the personal information ledger of the library management device 2, but the recitation code is input separately from the worker code. Then, each of these codes may be checked. Further, in this case, the approver may read a storage medium such as an IC card storing the employee code of the employee into the terminal device (LT) and then input the recitation code. This can be similarly applied to the client.

Further, in the above embodiment, the computerized storage / receipt request form is stored in the floppy disk (FD) 7 and submitted to the approver, but another storage medium such as an IC card is used instead of the FD. You may. Also, without using a storage medium, the computerized entry / exit request form is transmitted online from the client terminal device of the requester to the terminal device of the approver (supervisor) via the communication line, and the approved request form is sent to the approver of the approver. Alternatively, the terminal device may be configured to return online to the client terminal device.

Further, in the above-mentioned embodiment, at the time of approval processing of the entry / exit request form in the terminal devices (LT) 4a to 4m for superiors, the approved request form is transferred to the library management unit 2 to make a clean copy. However, this clean copy procedure may be omitted.

Further, in the library devices 1a to 1d of the above-described embodiment, each of the library devices 1a to 1d is configured to independently perform the loading and unloading processing operation. However, the rack portion 11 of each library device 1a to 1d is used. , 12 and the shelf management table 13 are integrated into one, and the integrated shelves 11 and 12 are integrated into the respective library devices 1a to 1d.
You may comprise so that it may respectively access from the storage part 14 and the output part 15 of this. In this way, for example, even if one of the library devices 1a to 1d falls into an inoperable state, another library device can be accessed instead. Further, each of the library devices 1a to 1d is independently configured as in the above-described embodiment, and is configured to be mutually accessible via a communication line between the library devices 1a to 1d as necessary. Good.

Further, the communication network may use another network such as a circuit switching network other than the loop transmission network. In addition, the gist of the present invention also relates to the configuration of the entire system and the procedure of loading and unloading, the number of library devices and their configuration and control procedure, the configuration and control procedure of terminal devices, the configuration and control procedure of library management device, etc. Various modifications can be implemented without departing from the scope.
