The present invention relates to an image processing system connected to a network.

In a network facsimile apparatus in which a plurality of workstation apparatuses, mail server apparatuses, and network facsimile apparatuses are connected via a LAN, and the network facsimile apparatus is connected to a telephone network, distribution of image information from the network facsimile apparatus to the user is performed using HTTP. There is a control method in which the server function is applied and electronic mail is not used at the time of image information distribution, and the burden on the mail server device is greatly reduced (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 10-341304

  In the network system described in Patent Document 1, electronic mail from the network facsimile apparatus to the user of the workstation apparatus is temporarily stored in the mail server apparatus, and the workstation apparatus and the network facsimile apparatus are sent to the mail server apparatus at an appropriate cycle. Inquiries about reception of e-mail addressed to the user of the user terminal, and when the e-mail addressed to the user is stored in the mail server device, the e-mail is received from the mail server device and To be notified.

  By the way, for example, the files received by each terminal via the telephone line network or the Internet are collectively managed by one (or a plurality of) servers rather than managed by each terminal, and the user of each terminal Although it is convenient to access the server so that it is possible to confirm what kind of file has arrived at each terminal, in the network system described in Patent Document 1, the network facsimile apparatus is connected to a telephone line network. However, each workstation device is merely connected to the LAN, and is not configured to be able to confirm what kind of file has arrived at each terminal.

  The present invention has been made paying attention to such problems, and a file server capable of efficiently managing the files transferred by each terminal, via such a file server and a network. It is an object of the present invention to provide a connectable image processing apparatus and an image processing system in which such a file server and an image processing apparatus are connected to a network.

In order to achieve the above object, a file server according to claim 1 of the present invention is capable of connecting an image file together with attribute information from an image processing apparatus via a network when the file server can be connected to a plurality of image processing apparatuses via a network. Receiving means for receiving, image storing means for storing image files received by the receiving means in association with attribute information, file list creating means for creating a file list relating to attribute information of image files in the image storing means, and file list When receiving a list request including an extraction condition (list target information) from the image processing apparatus and a file list storage means for storing the file list created by the creation means, the list data corresponding to the extraction condition is extracted based on the attribute information To create a file list for transmission and send it to the requesting image processing device List for storing and transmitting means for transmitting the file list, the list transmission permission setting information for specifying an image processing apparatus capable of extracting the list data when creating a transmission file list for the image processing apparatus of the list requestor A transmission permission setting information storage unit, wherein the transmission unit specifies an image processing device capable of list transmission based on the list transmission permission setting information for the image processing device to be listed in the list request, and transmits the list. The present invention is characterized in that list data corresponding to only image processing apparatuses determined to be possible is extracted to create a transmission file list.

In this file server, for the image processing devices to be listed in the list request, the image processing device that can send the list is specified based on the list sending permission setting information, and only the image processing device that is determined to be able to send the list is supported. List data to be extracted to create a file list for transmission.

  Here, the image file and the file list are different files. The attribute information is header information, and the attribute information (header information) is a separate file from the image file (main body).

  In this file server, the attribute information includes identification information of the image processing apparatus (information that can identify the multifunction peripheral), the list request includes list target identification information of the image processing apparatus to be listed as an extraction condition, and the transmission unit includes: It is preferable to extract the list data corresponding to the list target identification information from the file list stored in the file list storage means to create a transmission file list (with the configuration of claim 2).

  In this case, only the list data corresponding to the image file received from the specific image processing device is extracted from the file list for all the image files received from the plurality of image processing devices to create the transmission file list. The specific image processing device to be extracted is one or more image processing devices designated by the requesting image processing device.

  Here, as the extraction condition, in addition to the identification information of the image processing apparatus, an acquisition method (extract all scanned items or all received FAX items) can be used as the extraction condition. In this case, it is also possible that the acquisition method is FAX reception, and the acquisition method is received from a specific transmission source. In addition, date information can be used as an extraction condition. In this case, for example, it can be scanned and / or received from ** year ** month ** day to □ year ** month ** day.

In addition , list transmission permission information can be set for each image processing apparatus in the file server. When receiving the list request, the file server excludes, from among the image processing apparatuses that are the list target, apparatuses corresponding to the list transmission non-permission from the list target. That is, only devices corresponding to the list transmission permission are included in the list. List transmission permission setting information includes, for example, “Allow when requesting from own device but not when requesting from other device”, “Allow both when requesting from own device and requesting from other device. And “permit only when requested by a specific device”.

Further, the list request includes sort designation information in addition to the extraction condition, and the transmission means sorts the extracted list data based on the sort designation information and creates a sorted transmission file list. (Constitution of claim 3 ) It is preferable.

  Here, when the sort designation information indicates that there is a sort, the sort process is executed on the extracted list data, and the list data after the sort process is used as a transmission file list. Of course, when the sort designation information indicates no sorting, the sorting process is not executed.

  Further, not only the presence / absence of sorting but also the sort type can be designated by the sort designation information. As an example of the sort type, in addition to the case of sorting for each image processing apparatus, when the attribute information includes date and time information, it can be sorted according to the date and time (sorted in order of date and time). When the attribute information includes file size information, the attribute information can be sorted (sorted in size order) according to the file size. Alternatively, when the attribute information includes image file acquisition method information (for example, scan or FAX reception), the attribute information can be sorted (sorted for each acquisition method) according to the acquisition method.

On the other hand, in the image processing system according to claim 4, in which the file server and the plurality of image processing apparatuses are connected via a network, the file server includes means for receiving and storing the image file together with the attribute information from the image processing apparatus. A means for creating a file list relating to attribute information of the received image file; a list request including an extraction condition from the image processing apparatus; a file list for transmission corresponding to the received extraction condition; and a request for list request list for specifying means for transmitting the transmission file list to the image processing apparatus is based, an image processing apparatus capable of extracting the list data when creating a transmission file list for the image processing apparatus of the list requestor List transmission permission setting information storage means for storing transmission permission setting information, and the image processing apparatus Means for acquiring a file; means for transmitting the acquired image file together with attribute information to the file server; means for transmitting a list request including an extraction condition to the file server; and a file list as a response to the list request. The image processing apparatus includes: a receiving unit configured to receive a list of image processing devices that can transmit a list based on list transmission permission setting information for an image processing device that is a list target in a list request from the image processing device; The apparatus is specified, and list data corresponding to only the image processing apparatus determined to be capable of list transmission is extracted to create a transmission file list.

  In this image processing system, the file server and the image processing apparatus are connected via a network. The attribute information here includes at least identification information of the image processing apparatus (information for specifying the multifunction peripheral).

According to the first and fourth aspects of the present invention, the list transmission permission information for specifying an image processing apparatus from which list data can be extracted when creating a transmission file list for each image processing apparatus in consideration of security. By setting, it is possible to take out a necessary image file from a necessary image processing apparatus while maintaining a predetermined security (preventing unintentional secret leakage).

According to the second and fifth aspects of the invention, the user of the image processing apparatus can request a file list by designating a necessary image processing apparatus. For example, if there are A to C image processing devices, only the image files for the A and B image processing devices (image processing devices other than C) are specified by specifying the A and B image processing devices as a list target. You can receive the listed file list from the file server.

According to the third and sixth aspects of the invention, when the user of the image processing apparatus acquires a file list according to a predetermined extraction condition from the file server, the user can specify sort processing as necessary. It is easy to check the contents of the file list. In addition, when a file server is requested to transmit an image file body for a necessary file from the acquired file list, the necessary file can be easily selected.

  Hereinafter, the present invention will be described in more detail with reference to embodiments.

  FIG. 1 shows a block diagram of an image processing system in which an image processing apparatus (multifunction peripheral) and a file server (storage device) according to the embodiment are connected via a network. The multifunction devices 1 to 4 have both a facsimile function and a copy function, for example, and are connected to the Internet via a telephone line network or a LAN 6. These multifunction devices 1 to 4 and the file server 5 are connected via a LAN 6.

  FIG. 2 is a block diagram according to an example of the configuration of each of the multifunction machines 1 to 4. Each of the MFPs 1 to 4 includes a main control unit (CPU) 11, an NCU 12, a MODEM 13, a ROM 14, a RAM 15, an image memory 16, a display unit 17, an operation unit 18, an image reading unit 19, An image recording unit 20, a CODEC 21, and a LAN I / F 22 are provided, and these units are connected by a bus 25.

  The CPU 11 comprehensively controls each part constituting the multi-function peripheral in accordance with a program stored in the ROM 14. The NCU 12 is controlled by the CPU 11 to control connection to the public telephone line network (PSTN) 26 that is a communication line, and to send a dial pulse corresponding to the telephone number (including FAX number) of the communication partner. And a function of detecting an incoming call.

  MODEM 13 is an ITU (International Telecommunication Union) -T recommendation T.30. 30, T.M. 4 according to the facsimile transmission control procedure (facsimile communication procedure) according to FIG. 17, V. 27ter, V.I. The transmission data is modulated and the received data is demodulated in accordance with 29. Further, the MODEM 13 has a function of modulating transmission data, which is a digital signal, into an analog voice signal for transmission to the public telephone line network 26 via the NCU 12, and an analog received from the public telephone line network 26 via the NCU 12. The audio signal is demodulated into a digital signal.

  The ROM 14 stores a program and the like for controlling the operation of the entire multifunction machine. The RAM 15 stores data necessary for control by the CPU 11 and data that needs to be temporarily stored during the control operation. The image memory 16 temporarily stores received image data and image data read by the image reading unit 19.

  The display unit 17 displays various information such as the operation state of the multifunction machine, information input by the operation unit 18, a file list received from the file server 5, and the like. For example, a liquid crystal display (LCD) is used as the display unit 17. The operation unit 18 includes a numeric keypad, a mode switching key, a one-touch key, an abbreviated key, a registration key, a start key, a stop key, and the like.

  The image reading unit 19 reads image data on a document and outputs image data. The image recording unit 20 includes an electrophotographic printer, and records received image data, image data of a document read by the image reading unit 19 in a copying operation, and a file list received from the file server 5 on a recording sheet. The CODEC 21 encodes image data to be transmitted and decodes received image data. The LAN I / F 22 transmits / receives various data to / from other multifunction devices and the file server 5 via the LAN 27 (LAN 6 in FIG. 1).

  For example, the MFP acquires an image file body from another MFP via the LAN 27, and transmits the acquired image file body together with attribute information to the file server 5, or sends a list request including an extraction condition to the file server. 5 is received, a file list is received from the file server 5 as a response to the list request, and the received file list is output by the display unit 17 and / or the image recording unit 20. In this embodiment, since the image file and the attribute information are handled as separate files, the image file main body is the one excluding the attribute information.

  On the other hand, a block diagram according to an example of the configuration of the file server 5 is shown in FIG. The file server 5 includes a CPU 31, a ROM 32, a RAM 33, a hard disk 34, a CD drive 35, a display unit 36, an operation unit 37, and a LAN I / F 38, which are connected by a bus 39. Yes. The description of the same components as those of each of the MFPs 1 to 4 is omitted.

  The file server 5 receives the image file main body together with the attribute information from the multifunction peripherals 1 to 4 via the LAN 27, stores the received image file main body in association with the attribute information in the hard disk 34, and the image stored in the hard disk 34. When a file list related to attribute information of the file body is created or updated, the created or updated file list is stored in the RAM 33, or a list request including extraction conditions (list target identification information) is received from the multifunction devices 1 to 4. Based on the attribute information, list data corresponding to the extraction condition is extracted to create a transmission file list, or the transmission file list is transmitted to the multifunction peripherals 1 to 4 that are the list request sources.

  In the file server 5, the created or updated file list is always stored in the hard disk 34, and temporarily stored in the RAM 33 when there is a list request from the multifunction devices 1 to 4. For the file list stored in the RAM 33, the list data corresponding to the extraction condition is extracted based on the attribute information to create a transmission file list, which is stored in another area of the RAM 33. Is sent to the MFP that requested the request. Of course, the image file body is also stored in the hard disk 34.

  When the file server 5 receives the image file body from the multifunction peripherals 1 to 5, the file list created or updated based on the attribute information received together with the image file body is as shown in FIG. 4, for example. In the file list of FIG. 4, a serial number, file name / subject name, type (acquisition method), destination, date / time, size, and terminal name are stored. Here, the serial number, file name / subject name, type (acquisition method), destination, date / time, size, and terminal name mean the following.

  Serial number: Assigned to each image file body.

  File name / subject: Received from the MFP as attribute information or given on the file server side.

  Type: Image file body acquisition method (e-mail transmission / reception, FAX transmission / reception, scanning, etc.) in the multifunction device.

  Destination: The transmission source when the MFP receives the image file itself, or the transmission destination when it transmits.

  Date and time: Date, hour, minute and second when the type occurred.

  Size: Size (capacity) of the image file itself.

  Terminal name: Name of the MFP that is the sender of the image file itself to the file server (identification information of the MFP).

  For example, in the case of serial number 1, the terminal name A is at the destination user @ ***. co. jp indicates that the mail has been transmitted, and the size of the mail is 1057k. The file name / subject at this time is given “[Request] please process”, which is the contents of the mail. The serial number 2 indicates that the terminal name B received a fax from the partner 075672 *** on January 3, 2004 at 12:53:12 pm, and the size of the received fax is 24k. In this case, “075-672-****”, which is the FAX number of the other party (sender), is assigned to the file name / subject name. When the type is mail transmission / reception, the file name / subject is the mail subject. In this case, the mail subject is transmitted or received as attribute information. Here, the file name / subject name is assigned on the file server 5 side, but the multifunction device 1-4 side assigns the file name / subject name in advance based on a predetermined rule and includes it in the attribute information. Also good. Of course, the file name / subject assignment rule is not limited to that shown in FIG.

  As described above, when the file server 5 receives the image file main body from the multifunction peripherals 1 to 5, the file server 5 creates or updates the file list as shown in FIG. 4 based on the attribute information received together with the image file main body.

  Further, when the list request includes list target identification information of a multifunction peripheral to be listed as an extraction condition, the file server 5 extracts a list data corresponding to the list target identification information from the file list and creates a transmission file list To do. Further, the file server 5 stores list transmission permission setting information regarding the multifunction peripherals 1 to 4, and when receiving a list request including an extraction condition from the multifunction peripherals 1 to 4, the file server 5 is a list target in the list request. For the multi-function peripheral, a multi-function peripheral capable of list transmission is specified based on the list transmission permission setting information, and list data corresponding to only the multi-function peripheral determined to be capable of list transmission is extracted to create a transmission file list.

  Specifically, the file list as shown in FIG. 4 can be requested by each multifunction device, but not all multifunction devices can request all lists, but the target multifunction device that can request a list for each multifunction device. The machine is set. That is, in the file list of FIG. 4, when the list target identification information is a terminal name, [1] a list of file lists received by the own device on the multifunction device side, [2] received by a multifunction device other than the own device Either a list of file lists or [3] a list of file lists received by all multifunction devices can be designated, and the designated file list can be received from the file server 5. For example, if the terminal name of the own machine is A, [1] permits a request for a list of only terminal name A (serial numbers 1, 3, 4), and [2] allows terminal names B and C (serial numbers 2, 5). The list request of terminal names A, B, and C (serial numbers 1 to 5) is permitted in [3]. Thereby, use according to the characteristic of the apparatus of each terminal name A, B, and C and a condition can be performed.

  However, for example, even if the multifunction device requests the above [3], the list request from the multifunction device that is determined to be unsuccessful in list transmission based on the list transmission permission setting information on the file server 5 side is excluded. The file list transmitted to the MFP (acquired by the multifunction device) is limited to a list request only for the multifunction device determined to be able to send the list. Further, here, the identification information (terminal name) of each MFP is taken up as the extraction condition, but the type (acquisition method) and date / time may be used. The acquisition method may be, for example, extracting all transmitted emails, extracting all received faxes, or receiving from a specific source out of the acquisition methods of FAX reception. For example, the date and time may be transmitted and / or received from what day, month, day to year, month, day.

  Next, data transmission / reception when the image file body is transmitted from the multifunction peripherals 1 to 4 to the file server 5 will be described with reference to FIG. Data transmission / reception as shown in FIG. 5 and FIG. 6 is performed using a known protocol such as FTP. First, when the multifunction device (client) issues a request to open a session to the file server (server), the file server issues an ACK (normal reception) to the multifunction device. Thereby, a session is established between the multifunction peripheral and the file server. Next, the multifunction device transmits TxHeader (text header) as header information (attribute information) to the file server, and the file server sends ACK to the multifunction device.

  TxHeader is a data source (corresponding to the type (acquisition method) in FIG. 4), creation date / time (scan date / time, send / receive date / time, etc.), document name (subject / subject, etc. if specified), file format (tif / pdf) Etc.), file size (number of bytes of file), number of pages (number of pages of file), terminal name (identification name of MFP that created / received file), and the like. This TxHeader is a separate file from the image file body as described above.

  After transmitting the header information, the multifunction device transmits TxData1, TxData2, and TxData3 that are image file bodies to the file server in order, and the file server transmits ACK to the multifunction device after receiving each TxData1, TxData2, and TxData3. After the image file main body is transmitted, the session is disconnected when the MFP issues a request to the file server to close the session.

  Processing when each of the multifunction devices 1 to 4 issues a file list request to the file server 5 will be described with reference to FIG. First, when the multifunction device issues a request to open a session to the file server, the file server issues an ACK to the multifunction device, thereby establishing a session between the multifunction device and the file server. Next, the multifunction device sends TxRequest (text request) as an extraction condition included in the list request to the file server, and the file server sends ACK to the multifunction device in response to this.

  TxRequest is a terminal name, the number of list objects, a list object name, sort designation information, and the like.

  Terminal name: Name of the device (multifunction device) (identification information of the multifunction device). This is a mandatory / fixed length.

  Number of list objects: The number of MFPs to be listed (for example, the total number of MFPs in the case of 0), which is necessary for identifying the data length of the next list object name. This is a mandatory / fixed length.

  List target name: List of MFPs to be listed (the above terminal name). This is optional and variable length.

  Sort specification information: In addition to specifying whether or not to sort, a sort type can also be specified. This is optional and fixed length.

  When the sort type is also specified in the sort designation information, it is possible to sort according to the attribute information in addition to sorting for each multifunction device (terminal name). For example, when the attribute information includes date and time information, it can be sorted according to the date and time. Specifically, if the entire list is rearranged in order of date and time in the example of FIG. 4, it is as illustrated (in the order of serial numbers 1 to 5). In addition, when the attribute information includes file size information, it can be sorted according to the file size. If the entire list is rearranged in order of size in the example of FIG. 4, the rearrangement is such that serial number 1 is first, next serial number 4, ..., and finally serial number 2. In addition, when the attribute information includes image file acquisition method information (for example, mail transmission / reception or FAX transmission / reception), it can be rearranged for each acquisition method.

  The file server returns ACK / NACK indicating whether or not the TxRequest has been normally received, and then “request multifunction device permission setting confirmation”, “list target multifunction device list”, “list target data extraction”, “sort” Preparation of transmission data (creation of a file list for transmission) is performed by performing "shaping according to a request".

  When the file server sends an ACK that has successfully received TxRequest to the multifunction device, the file server subsequently checks whether there is data to be transmitted and whether the multifunction device that issued the list request is permitted to list requests. If the confirmation is OK, TxStart is transmitted to the multi-function peripheral as a start notification of image file main body transmission. On the other hand, if there is data to be transmitted, if the confirmation is NG, and if the confirmation is OK, if there is no data to be transmitted, Complete is transmitted to the multifunction device. Here, the case where there is no data to be transmitted is one case where the extraction condition included in the list request does not exist in the file list. Specifically, in FIG. 4, if the extraction condition is a terminal name, for example, the terminal name D is a list target. Secondly, even if the extraction condition is in the file list, list transmission non-permission is set as list transmission permission information for the multifunction peripherals to be listed on the file server side, and data that can be transmitted (transmission is permitted). This is when there is no data.

  When the file server transmits TxStart to the multifunction device, the created transmission file list TxData2 and TxData3 are sequentially transmitted to the multifunction device, and the multifunction device transmits ACK to the file server after receiving each TxData2 and TxData3. After transmitting the transmission file list, when the file server transmits Complete to the multifunction device as a transmission file list transmission completion notification, the multifunction device issues a request to close the session to the file server.

  Next, for example, processing in the multifunction device 1 when requesting a file list from the multifunction device 1 (client) to the file server 5 will be described with reference to the flowchart of FIG. First, in step ST1, it is determined whether there is a list request for retrieving a file list stored in the file server 5 in the operation. When there is a list request by an input from the operation unit 18, in step ST2, "Please enter the name of the terminal to be listed" is displayed on the display unit (LCD) 17 of the own device. Next, in step ST3, the user waits for “determination” input from the operation unit 18, and in step ST4, it is determined whether a list is input.

  When the list is input, in step ST5, data such as the number of objects to be listed and extraction of the names of terminals to be listed are set for transmission to the file server 5 as described above. On the other hand, when the list is not input, in step ST6, the list-up target is set for all the multifunction peripherals, and the data is similarly set to be transmitted to the file server 5. Thereafter, in step ST7, request data is created. In step ST8, a session is started with respect to the file server 5, and a list request is transmitted.

  In the next step ST9, data from the file server 5 is received. In step ST10, it is determined whether it is “Complete”. If NO, that is, if “TxStart” is received, step Returning to ST9, data reception from the file server 5 is continued. In step ST10, if “Complete” is received immediately after the session is started or “Complete” is received during data reception, the determination becomes YES, and in step ST11, the session is closed and the processing ends.

  Processing in the file server 5 when requesting a file list from the multifunction device 1 (client) to the file server 5 will be described with reference to the flowchart of FIG. In step ST21, it is determined whether there is a list request from the multi-function device 1. If there is, a list request data is received in step ST22. Next, in step ST23, permission settings for the list requesting terminal name are extracted, and in step ST24, it is determined whether there is a multi-function machine that permits list-up. The permission / non-permission of this listing is as described above.

  If there is a multifunction device that permits the listing, in step ST25, data relating to the permitted multifunction device is extracted. As described above, the data relating to the multifunction peripheral is as shown in FIG. 4, for example. Then, in step ST26, it is determined whether or not the data rearrangement (sorting) is specified. If the data is specified, the sorting process is performed in step ST27. If the data is not specified, step ST27 is skipped.

  Thereafter, in step ST28, the sorted data or the data that has not been sorted is sent to the multi-function peripheral 1 that requested the list. In step ST29, it is determined whether all data has been transmitted. If not, the process returns to step ST28 and continues to transmit data. When the transmission of all data is completed, the determination in step ST29 is YES, and in step ST30, a data end notification is transmitted to the MFP 1 that has requested the list, and the process ends.

  The processing of each multifunction device 2-4 and the file server 5 when requesting a file list from the other multifunction devices 2-4 to the file server 5 performs the same processing as shown in FIGS.

  In the above embodiment, the MFPs 1 to 4 individually transmit the image file body and attribute information (header information) to the file server 5, and the file server 5 stores them as separate files. The main body and the attribute information may be processed as the same file. That is, the MFPs 1 to 4 may transmit the image file body and the attribute information to the file server 5 as the same file, and the file server 5 may store them as the same file.
