(First embodiment)
FIG. 1 is a block diagram showing a configuration example of a document circulation system including a portable image display device 1 according to the first embodiment of the present invention. This document circulation system includes a portable image display device 1, an MFP 11 (multifunction device) 11, a network 19, and personal computers (hereinafter referred to as PCs) 20 to 21 of users.

  In this embodiment, a digital paper (electronic paper) 1 that is a portable image display device 1 holds a plurality of various document data in a plurality of document holding units 5 inside, and displays them on a screen display unit 6. As an image.

  The control unit 2 controls the portable image display device as a whole. As an internal parameter, the DP / ID for identifying the portable image display device itself and connection with the portable image display device are permitted. Have a connectable MFP ID. The instruction unit / additional data input unit 4 is a user input interface for the user to press a key or input additional data, as will be described later.

  The IC card reader / writer 8 is for reading and writing data in the IC card 9 which is a removable storage medium. The IC card 9 holds personalized data 10 for the owner of the IC card 9 who is the current operator of the portable image display device.

  The rechargeable battery 7 is a power supply unit of the portable image display device 1 and is charged via the power supply line 23 when the portable image display device 1 is mounted on the MFP 11.

  The MFP-I / F 3 is an interface (I / F) with the MFP 11, and when the portable image display device 1 is attached to the MFP 11, the MFP-I / F 3 is connected between the portable image display device 1 and the MFP 11. In order to transmit / receive various document data, destination information, and the like via the signal line 22. In the present embodiment, the signal line 22 is realized by wire by USB, but may be realized by radio such as infrared communication.

  Usually, the digital paper 1 is carried offline and used for circulation without being attached to the MFP 11. At the time of browsing, each reader inserts his / her own IC card 9 into the IC card reader / writer unit 8 for use.

  The MFP 11 is a multifunction device having a copy function, a scan function, and a print function. In the present embodiment, the MFP 11 further has a function as a parent device of the portable image display device 1. First, the MFP 11 has a function of supplying charging power to the portable image display device 1 via the power line 23 by the power supply unit 17. As a result, the portable image display device 1 is advantageous in that it is not necessary to have an AC power supply unit, and is lighter and less expensive.

  Next, the MFP 11 has a function of writing a document to the portable image display device 1. First, document data to be written to the portable image display device 1 is sent to the MFP 11 from various PCs or the like on the network, and held in an area corresponding to each portable image display device to be written in the DP spool area 16.

  This sending may be performed at any timing, and the portable image display device 1 does not need to be attached to the MFP 11. An image obtained by reading an unillustrated document by the image reading unit 14 of the MFP 11 is also held in an area corresponding to each portable image display device to be written in the DP spool area 16 in accordance with an instruction from the operator. .

  Then, when the portable image display device 1 is attached to the MFP 11 at an arbitrary timing, the MFP 11 receives which DP · ID of the attached portable image display device 1 to thereby determine which portable image display device 1. Recognize whether is installed. Then, the document data in the region corresponding to the mounted portable image display device in the DP spool region 16 is transmitted to the portable image display device 1 via the DP-I / F 12.

  Next, the MFP 11 has a function of receiving document data or the like from the portable image display device 1 and printing the data or transferring it to each PC on the network. First, print document data to be printed by the MFP 11 is received from the portable image display device 1 via the DP-I / F 12 and printed.

  Further, transfer document data and destination information to be transmitted from the portable image display device 1 to the PCs 20 to 21 on the network are transmitted from the portable image display device 1 via the DP-I / F 12. Receive and send the mail to the designated destination via the N / W-I / F 13. The portable image display device 1 may be detached from the MFP 11 at the time when these prints and mail transmission are actually performed.

  As described above, the portable image display apparatus 1 according to the present embodiment does not have an N / W-I / F, and uses the N / W-I / F 13 of the shared MFP 11, thereby allowing the portable image display apparatus 1. There is an advantage that the cost can be reduced and a troublesome N / W setting is unnecessary. Further, since the necessary document data can be printed simply by mounting the portable image display device 1 on the MFP 11, there is an advantage that troublesome printer settings are not required. Further, since the necessary document data can be transmitted simply by mounting the portable image display device 1 to the MFP 11, there is an advantage that troublesome transmission settings are unnecessary.

  Further, the MFP 11 has a copy function. The image reading unit 14 reads a paper document (not shown), and the read image data is sent to the image forming unit 15 to form a copy image.

  Further, the MFP 11 has a network scanner function. The image reading unit 14 reads a paper document (not shown), and the read image data is sent to the PCs 20 to 21 of each user via the control unit 18, the network I / F 13, and the network 19.

  Further, the MFP 11 has a network print function. Document data and image data received from each user's PCs 20 to 21 via the network 19, the network I / F 13 and the control unit 18 are expanded as necessary and sent to the image forming unit 15 as image data. Printed.

  The control unit 18 of the MFP 11 controls the entire MFP 11 and represents, as internal parameters, an MFP ID for identifying the MFP 11 itself and a portable image display device that is permitted to connect to the MFP 11. Have a connectable DP / ID.

  FIG. 2 is an external view of the MFP 11 when the portable image display device 1 is mounted. Normally, the portable image display device 1 is carried and used at an arbitrary place. However, when receiving, transmitting, printing, and charging a document, as shown in FIG. Is attached to the DP-I / F section 12. In FIG. 2, reference numeral 24 denotes an original platen unit of the original reading unit 14, and reference numeral 25 denotes an operation unit of the MFP 11. As described above, the display image of the portable image display device 1 can be confirmed by mounting in the mounting slot at the top of the MFP 11 even when the MFP 11 is mounted.

  FIG. 3 shows the structure of an electrophoretic display device used in the screen display unit 6 of the portable image display device 1 of the present embodiment. For example, as described in detail in Japanese Patent Application Laid-Open No. 2002-72258 and the like, the electrophoretic display device includes a dispersion system 33 composed of charged particles 32 and an insulating liquid 31 as shown in FIG. A pair of electrodes 38 and 39 is disposed between the substrates 36 and 37 with a partition wall 42 interposed therebetween.

  In this configuration, when a voltage is applied between the electrodes 38 and 39, the charged particles 32 can be attracted to the side of the electrode having the opposite polarity to the charge of the particles themselves. Here, by coloring the insulating liquid 31 and the charged particles 32 in different colors, display can be performed according to the direction of the electric field applied to the electrodes 38 and 39.

  That is, when the charged particle moves to the side of the electrode 37 located on the side opposite to the observer when the substrate 36 side is the observer side, the charged particle 32 is given to the observer as shown on the right side of FIG. Is not recognized, and the color of the insulating liquid 31 is observed.

  On the other hand, when the charged particles 32 are moved to the electrode 38 side by reversing the electric field applied between the electrodes 38 and 39, the observer is charged with the charge adhering to the electrode 38 as shown on the left side of FIG. The color of the particles 32 is observed, and two-color display can be performed by the colors of the charged particles 32 and the insulating liquid 31.

  Further, when the charged particles 32 are moved to the electrode 38 (/ 39) side, the voltage applied to the electrode 38 (/ 39) is turned off by configuring the fixing layer 40 (/ 41) to be charged. Even when the charge particles 32 are reduced, the charged particles 32 can remain attached to the fixing layer 40 (/ 41), and the power consumption in a state where the display does not change can be reduced.

  The electrophoretic display device as shown in FIG. 3 is a reflective display device that displays light by reflecting light from the outside with charged particles or an insulating liquid. There is a feature that the upper character is less visible than the liquid crystal display device, and the visibility is good.

  In addition, no backlight is required, and since charged particles are attracted to each electrode in the fixing layer, only a small amount of power is required to maintain the display of a still image, resulting in low power consumption. There is. In addition, since a glass frame or the like is unnecessary as compared with a liquid crystal display device, it is light. In addition, there is a feature that the cost does not increase even with a large screen. Therefore, it is suitable for a display device such as a portable large-screen circulation, which does not rewrite the display much, but has a desire to always maintain the image display.

  FIG. 4 is another configuration diagram of the screen display unit in the portable image display device. The configuration of the electrophoretic display device used in the screen display unit 6 of the present embodiment is not limited to the configuration shown in FIG.

For example, as shown in FIG. 4A, a configuration in which the electrodes 38 and 39 for applying a voltage to the dispersion system are arranged in a direction perpendicular to each other may be employed. In the figure, reference numeral 34 denotes a light shielding layer.
Further, the configuration of the electrophoretic display device may be a configuration in which microcapsules are filled with a dispersion system as shown in FIG. In this configuration, the coating film 35 of the microcapsule can be used as a fixing layer in this configuration by performing a charging process. At this time, the fixing surface of the charged particles 32 is the inner wall of the microcapsule coating 35.

  Furthermore, as shown in FIG. 4C, the configuration of the electrophoretic display device is such that the electrodes 38 and 39 are arranged on the same substrate via the insulating layer 43, and the charged particles 32 move in parallel to the substrate surface. It may be configured. In this case, the fixing layer 40 is formed on the surface of the insulating layer 43.

FIG. 5 is a diagram illustrating an example of an operation screen displayed on the screen display unit 6 of the portable image display device 1.
The screen display unit 6 is configured by the electrophoretic display device described with reference to FIGS. 3 and 4, and a touch panel is mounted on the surface thereof, so that an input to a key at an arbitrary position or a pen at an arbitrary position The additional character input can be detected by the instruction unit / additional data input unit 4.

  In FIG. 5, first, in the area 51, the User ID in the currently installed IC card 9 is displayed, and the document ID of the currently displayed document is also displayed. Further, in the area 52, the contents of the document are displayed.

  Here, the characters in the area 58 are not included in the original document, and the additional writing data added by the operator with the pen is displayed. The key 53 instructs the display of the previous document, while the key 56 instructs the display of the next document.

  The key 54 is used to instruct the original data of the displayed document to be transmitted to the mail address of the operator, and the key 55 is used to instruct to print the displayed document.

  When these transmission instructions and print instructions are performed, a print instruction flag and a transmission instruction flag (not shown) of each document are set to 1, and when the document is displayed, depending on whether each flag is 1, An area 57 displays whether or not a print instruction or transmission instruction has been completed.

  In this embodiment, when the key 54 or 55 is further pressed in the instructed state, a toggle operation for canceling the instruction is performed, but an instruction canceling key may be explicitly provided.

  Since the portable image display apparatus 1 is normally carried offline and used, even if a print instruction or a transmission instruction is given in FIG. 5, the portable image display apparatus 1 is not immediately executed. This is executed when the MFP 11 is attached.

  As described above, there is an advantage that paper consumption can be reduced by circulating on the shared portable image display device 1 and printing only what is really necessary on the paper so that it is owned by the individual. .

  In addition, by browsing with the shared portable image display device 1 and transmitting only the electronic data of what is really necessary to the personal computer to own it, the paper consumption can be further reduced. There is an advantage.

  FIG. 6 is a diagram for explaining element information of each document held in the multiple document holding unit 5. First, L101 to L111 are element information of the first document, L112 to L122 are element information of the second document, and element information of the third and subsequent documents continues in the same manner after L123. Regarding the first document, the document number in DP of L101 is a management number indicating the serial number of each document held in the multiple document holding unit 5 of the portable image display device 1.

  Next, the document ID of L102 is an identification number of each document uniquely assigned to each document in the entire document circulation system. Next, the display document data of L103 is data used when this document is displayed on the screen display unit 6 as shown in FIG. L103 describes the file name of the document data for display, and the file entity is held in another area of the plural document holding unit 5.

  In the case of the present embodiment, the display document data is held in a low-resolution JPEG format that is a common format for all documents. As a result, in order to display each document, only a viewer that displays JPEG is required, and various applications are not necessary. In addition, the display processing when displaying low-resolution JPEG format data is light, so that the time required for display is short, and an expensive CPU and memory are not required, and it can be displayed by an apparatus having an inexpensive configuration. There are advantages.

  This display document data is created by an external PC or MFP 11 based on original document data or print original document data, which will be described later, and is sent to the portable image display device 1 as one element of the document.

  Next, the original document data of L104 is the original data of this document, is held in a format specific to each application that created this document, and is in a format that can be edited by each application. In order to display these original document data, those applications need to be included in the portable image display device 1. In the portable image display device 1 according to the present embodiment, these original document data are stored. Since only the transfer is performed without displaying, there is an advantage that these applications do not need to be included, and conversely, there is an advantage that document data created by an arbitrary application can be handled.

  Next, the original document URL of L105 is location information on the network where the latest original document data exists. The original document data of L104 is document data of the original application at the time of creating this document, and there is a possibility that it has been updated thereafter. Therefore, in the present embodiment, the latest original document data is placed on a file server (not shown) on the network, the data is updated, and the URL is distributed as an element of each document.

  As a result, the latest original document data can be accessed by accessing this URL. However, since the portable image display device 1 of the present embodiment is normally used offline that is not connected to the network and cannot access the file server, the original document data of L104 is normally used.

  Next, the original document data for printing in L106 is data in an optimum format when this document is printed, and in the case of L106, it is data in PostScript format. By having such PDL data in PostScript format as original document data for printing as an element of each document, if it is sent to each printer such as the MFP 11, the PDL data is processed by each printer and high-quality images are obtained. An output image can be obtained.

  On the other hand, for example, if the display document data is printed, the display document data has a low resolution JPEG format, which causes a problem that the quality of the print image is deteriorated. In the case of printing, there is a problem that each application that created the original document data is necessary to print it.

  Next, the additional write data in L107 is additional write data written by the operator as described in FIG. 5, and is held independently of other document elements such as display document data. Next, the attribute information of L108 is a keyword representing the type of the document, and is sent to the portable image display device 1 as one element of the document. In the case of L108, this document indicates that the document has a relationship between Trip and A-Town.

  Next, the display permission information of L109 describes the User ID of a user who can view this document. In the case of L109, when the User ID is included in 012345-002350, 012385, 005000, it indicates that browsing of this document is permitted. Next, the print permission information of L110 describes the User ID of a user who can print this document.

  Next, the transfer permission information of L111 describes a mail address of a destination to which this document can be transferred. In the case of L111, the mail address indicates that this document can be sent to a destination of *** @ A-town, kawasaki-city.com (*** is optional). In this way, by writing permission information for various operations for each document and restricting various operations accordingly, it is possible to construct a document circulation system with high security strength.

  In the present embodiment, display document data always exists for each document, but original document data, original document URL, original document data for printing, and additional data may not necessarily exist. The transfer permission information of the first document is an instruction to permit / deny the destination mail address as in L111, but is not limited to this, and the transfer of the second document in L122 is not limited to this. Like permission information, permission / non-permission may be instructed regarding the User ID for transmission.

  FIG. 7 is a diagram for explaining the personalized data 10 held in the IC card 9. Although the portable image display device 1 is a shared device for circulation, in the present embodiment, the portable image display device 1 is personalized with personalized data held in the IC card 9 to improve usability. I am doing so.

  In FIG. 7, L201 is the User ID of the owner of the IC card 9, that is, the operator who is currently using the portable image display device 1. Next, L202 is the e-mail address of this operator. Generally, when e-mail is transmitted to this e-mail address, the e-mail reaches the PC owned by this operator on the network.

  Next, L203 is the preference information of this operator, and in the case of this operator, it means that Trip, Garden, and Photo type documents are preferred in this order. In the case of a paper circulation, the circulation contents are common to all the readers. However, in the portable image display device 1 according to the present embodiment, the circulation contents are sorted according to the preference information for each operator. Thus, the operator is displayed in order from the matter of interest, and the time for checking the circulation can be shortened.

  Next, L204 is filter information for non-display processing of this operator, and this operator means that display of a document of Woman or Diet type is unnecessary. In the case of a paper circulation, the circulation contents are common to all the readers. However, in the portable image display device 1 of the present embodiment, the circulation contents are filtered according to the filter information for each operator. Thus, matters that the operator is not interested in are not displayed, and there is an effect that the operability can be improved by eliminating the time for checking unnecessary circulations.

  Next, L205 to L207 are DP • IDs of portable image display devices that can be used by the operator. This is to prevent unauthorized persons from using the portable image display device 1. L208 to L209 are MFP IDs of the MFP 11 that can be used by the operator. This is for preventing unauthorized persons from connecting the portable image display device 1 to the MFP 11. In this embodiment, the DP • ID and the MFP • ID are realized by IPv6 format IP addresses assigned to the respective apparatuses, as shown in FIG. The IPv6 (Internet protocol version 6) is a new rule for a data transfer system (IP) used on the Internet.

  FIG. 8 is a diagram for explaining the display order information 59 that has been sorted by the preference information in the personalized data of FIG. 7 and further filtered by the non-display processing filter information. For example, when each document described with reference to FIG. 6 is held in the plural document holding unit 5 of the portable image display device 1 and an IC card 9 of a certain user is attached, these documents are stored in the IC card 9. Are sorted by preference information in the personalized data, and further filtered by non-display processing filter information.

  In FIG. 8, first, L301 is a display pointer indicating the number of the currently displayed document. In the case of L301, it indicates that the fourth document is currently being displayed. Next, L302 is the number of displayed documents excluding documents that are determined not to be displayed by the non-display processing filter information. In the case of L302, 20 documents are indicated. Next, the display order of the documents displayed after L304 is represented, and the number corresponds to the document number in DP described with reference to FIG.

  As described in the preference information in the personalized data in FIG. 7, the operator likes the Trip, Garden, and Photo type documents in this order, and is held in the multiple document holding unit 5. First, a plurality of documents having the attribute “Trip” are searched for and placed at the top as in L304 to L307.

  Next, the one having Garden as an attribute is searched and placed next as L308 to L310. Next, the one having Photo as an attribute is searched and arranged next as L311 to L313. Next, of the remaining documents, those having attributes of Woman and Diet are excluded and placed next as L314 to L316.

  In this embodiment, each document has attributes such as Trip, Garden, and Photo, assuming circulation in the local community. For example, in the case of circulation within a company, the project name or organization It may have attributes such as name.

FIG. 9 is a flowchart illustrating a processing procedure performed on the MFP 11 side.
First, when activated, it is checked in step S101 whether the digital paper 1 that is the portable image display device 1 is newly attached to the MFP 11 as shown in FIG. As a result of the determination, if the digital paper 1 is not loaded, the process proceeds to step S102, and other processes such as a copy process, a scan process, and a print process are executed, and then the process returns to step S101.

  On the other hand, if the result of determination in step S102 is that the digital paper 1 is newly attached to the MFP 11, the process proceeds to step S103 to start charging the digital paper 1, and the digital paper 1 is connected via the DP-I / F 12. Receives the DP ID from. Conversely, the MFP / ID of the own apparatus is transmitted to the digital paper 1.

  In step S104, the received DP / ID is compared with the connectable DP / ID held in the control unit 18 to determine whether the combination is connectable. If the result of this determination is that the combination is not connectable, no connection is made and processing returns to step S101.

  On the other hand, if the result of determination in step S104 is that the combinations are connectable, the process proceeds to step S105, where each of the DP spool areas 16 to be transmitted to the digital paper 1 from the area corresponding to the received DP / ID. Document data is read and transmitted to the digital paper 1 via the DP-I / F 12.

This document data includes each element such as the document ID, the display document data, the original document data, the original document URL, the attribute, and various permission information described with reference to FIG.
In step S106, print document data to be printed is received from the digital paper 1 via the DP-I / F 12, and printing of the received print data is started.

  At this time, when document data and additional data are received as document data for printing, they are combined in the MFP 11 to form a combined image similar to the state displayed in the image display area 52 of FIG. Print.

  In step S107, the transfer document data to be transferred and the destination information are received from the digital paper 1 via the DP-I / F 12, and the transfer document data is sent to the mail address specified by the destination information. Send mail.

  In step S108, the transfer status and print status are displayed on the operation unit 25 of the MFP 11. The transfer status is, for example, a display indicating that the transfer has been normally completed, an error that the transfer could not be performed, a display indicating from which digital paper the transfer request was made, and the like. For example, printing progress display of each document.

  In the present embodiment, when a transfer request or print request is received from the digital paper 1, it is processed as it is. However, the operator individually confirms various requests using the operation unit 25 of the MFP 11. Later, printing or transfer may be executed. The former has an advantage that the operator's processing is less, and the latter has an advantage that printing and transfer due to an erroneous operation can be prevented.

  Furthermore, in this embodiment, when a transfer request or print request is received from a digital paper, it is processed as it is. However, the requested print setting and transfer setting are processed by the operation of the MFP 11. You may enable it to be added or changed with the operation unit of the unit 25.

  The former has the advantage that the method of use can be limited because it is not changed arbitrarily, but the latter has the advantage that the degree of freedom of convenience is increased, and the printing style unique to the MFP 11 such as a finishing instruction can be designated by the operation unit 25 of the MFP 11. is there.

FIG. 10 is a flowchart of main processing on the digital paper 1 side in the portable image display device 1 and corresponds to FIG. 9 which is a flowchart on the MFP 11 side.
First, when activated, in step S201, it is checked whether the digital paper 1 is newly attached to the MFP 11 as shown in FIG.

  If the result of this check is that a new digital paper 1 has not been loaded, then in step S202, display processing, etc., which will be described later with reference to FIG.

  On the other hand, as a result of the determination in step S201, if the digital paper 1 is newly attached to the MFP 11, the process proceeds to step S203, and charging of the digital paper 1 is started. Also, the DP • ID of the own apparatus is transmitted to the MFP 11 via the DP-I / F 12, and conversely, the MFP • ID of the MFP 11 is received from the MFP 11.

  Next, in step S204, the received MFP • ID is collated with the connectable MFP • ID held in the control unit 2, and if the combination is not connectable, the connection is not performed and the process returns to step S201. .

  Further, in step S204, the received MFP • ID is checked against connectable MFP • ID (L208 to L209 in FIG. 7) in the personalized data in the IC card 9, and if the MFP 11 is not connectable, the connection is established. Without returning to step S201.

  On the other hand, in the case of a connectable combination, first, in step S205, each document data in the area corresponding to the DP / ID of the own apparatus in the DP spool area 16 in the MFP 11 is converted into the DP-I / F 12. Via the MFP 11. This document data includes each element such as document ID, display document data, original document data, printing original document data, original document URL, attributes, and various permission information described with reference to FIG.

  In step S206, as will be described in detail later with reference to FIG. 11, the document data for printing to be printed is transmitted to the MFP 11 via the DP-I / F 12, and printing is requested.

In step S207, as will be described in detail later with reference to FIG. 12, the document data for transfer and destination information to be transferred are transmitted to the MFP 11 via the DP-I / F 12, and the transfer is performed. Ask.
In step S208, the transfer status and print status are displayed on the screen display unit 6 of the digital paper 1. Thereby, the transfer status and the print status can be confirmed on the screen of the digital paper 1 as well.

FIG. 11 is a flowchart for explaining the details of the print data sending process of the portable image display device in step S206 of FIG.
First, in step S301, it is checked whether or not the original document data for printing is included in the corresponding document for which a print instruction has been issued. If the original document data for printing is included as a result of this check, the process proceeds to step S302, where the original document data for printing and additional data are transmitted to the MFP 11 to request printing.

  On the other hand, if the result of the check in step S301 is that the original document data for printing is not included, in step S303, the original document data for display and additional data are transmitted to the MFP 11 to request printing.

  Next, in step S304, it is checked whether or not the processing has been completed for all the documents. If the processing has not been completed, the processing returns to step S301 for the document for which the next print instruction has been issued. On the other hand, if the processing has been completed for all documents, the flow returns to the flow of FIG.

  In the present embodiment, the original document data for printing is sent at the time of printing, but the original document data may be sent. The former is advantageous in that PDL data, which is data in an optimal format for printing, can be sent to the MFP 11 and processing on the MFP 11 side is easy, but the latter is advantageous in that the original document data for printing and the original There is an advantage that the document data can be unified.

  FIG. 12 is a detailed flowchart of the transfer data sending process of the portable image display device in step S207 of FIG. First, in step S401, it is checked whether or not the original document data is included in the corresponding document for which the transfer instruction has been issued. If the original document data is included as a result of this check, the process advances to step S402 to transmit the original document data, additional data, and destination information to the MFP 11, and send the original document data to the designated destination. Request transfer of postscript data.

  On the other hand, if the original document data is not included as a result of the check in step S501, in step S403, the display document data, the additional data, and the destination information are transmitted to the MFP 11 for display at the designated destination. Request transfer of document data and additional data. In this embodiment, as the destination information, the operator's own mail address (L202 in FIG. 7) in the personalized data 10 acquired from the IC card 9 is automatically used as the destination information in step S502 in FIG. Is done.

  Next, in step S404, it is checked whether processing has been completed for all documents. If the result of this check is that processing has not been completed, the process returns to step S401 for processing for the next transfer-instructed document. On the other hand, if the processing has been completed for all documents, the flow returns to the flow of FIG.

  In the present embodiment, when the original document data is not included in the corresponding document, the display document data is sent instead. However, even if the original document data is included in the corresponding document, it will be described later. As in the second embodiment, when transfer of original document data is not permitted, display document data may be sent instead.

FIG. 13 is a flowchart for explaining detailed contents such as display processing of the portable image display device 1 in step S202 of FIG.
First, in step S501, it is checked whether or not the IC card 9 is newly attached to the portable image display device 1. As a result of this check, if the IC card 9 is newly installed, the personalized data 10 is obtained from the newly installed IC card 9 in step S502, and then the process proceeds to step S503, where the obtained personalized data is obtained. According to the preference information in the data, as described with reference to FIG. 8, the documents in the portable image display device 1 are sorted to determine the display order.

  Next, in step S504, first, the display permission information of each document described in FIG. 6 is compared with the User ID in the IC card 9, and display to the User ID in the IC card 9 is permitted. If there is no document, it is deleted from the displayed document list. Next, according to the non-display processing filter information in the obtained personalized data, as described with reference to FIG. 8, among the documents in the portable image display device, the document to be hidden is displayed from the display document list. delete.

  Further, the available DP / ID (L205 to L207 in FIG. 7) in the obtained personalized data is checked, and if the DP / ID of the own device is not included, this user basically uses this DP. Documents that are determined to be unusable and are subject to some kind of access control are deleted from the display document list.

  In this embodiment, as described above, even for a user who is not permitted to use, a document for which no access control is designated can be browsed. On the other hand, no operation may be performed.

  On the other hand, if the IC card 9 is not newly installed as a result of the check in step S501, the process proceeds to step S505, the display order determined in step S503 or step S504, and the display pointer representing the current display document. Based on the value of the display document, the display document is determined, and as shown in FIG. 5, the display document data of the display document is displayed on the screen display unit 6, and if there is additional data to the document, It is also synthesized and displayed.

  Next, in step S506, the operator waits for key input or writing input, and when the transfer instruction key in FIG. 5 is pressed, the process proceeds to step S507, and the transfer permission information for the corresponding document described in FIG. And the User ID and the destination mail address in the IC card 9 are collated. If the transfer is permitted as a result of the collation, a transfer flag (not shown) in the document data being displayed is set to “1” in step S508, and then the flow returns to the flow of FIG.

  If the print instruction key in FIG. 5 is pressed in step S506, the print permission information of the corresponding document explained in FIG. 6 and the User ID in the IC card 9 are collated in step S509. If printing with the User ID in the IC card 9 is permitted, in step S510, a print flag (not shown) of the document data being displayed is set to 1, and the flow returns to the flow of FIG.

  If the previous instruction key or the next instruction key in FIG. 5 is pressed in step S506, the display pointer is increased or decreased according to the instruction in step S511, and the flow returns to the flow in FIG. In step S506, when writing is performed as in the area 58 in FIG. 5, in step S512, the written additional data is associated with the document data being displayed as described in FIG. And return to the flow of FIG.

  In the present embodiment, for simplification of explanation, the flowchart of the process when the IC card 9 is removed is not described. However, when the IC card 9 is removed, or after the power is turned on, the IC card 9 is When not attached, the processing of step S503 and step S504 is executed based on unillustrated default personalized data stored in the control unit 2, and the display document and its display order are determined.

  At this time, for example, only document data permitted for all persons can be displayed or printed, so that some documents can be accessed even for persons who do not have the IC card 9. be able to.

  On the other hand, with the configuration of the present embodiment, when displaying, printing, and transferring a document with some access restrictions, an IC card 9 of a user permitted to access for each of those operations is required. A highly secure document circulation system can be constructed.

  In the present embodiment, when the IC card 9 is removed, the additional data entered by the operator is cleared. However, this may not be cleared. The former has the advantage that there is less risk of other readers misunderstanding by the written data by others, and the latter has the advantage that it can be used as a message version between the readers.

(Second Embodiment)
The second embodiment of the present invention is different from the first embodiment in the mounting destination of the portable image display device 1, the acquisition means of personalized data, the acquisition means of destination information, and the acquisition of various permission information. Only the means, the permission unit of various permission information, the representation method of original document data, and the like are different. For this reason, only a difference part is demonstrated.

  FIG. 14 is a block diagram of a document circulation system including the portable image display device 1 according to the second embodiment. This document circulation system includes a portable image display device 1, a dedicated cradle 64, a network 19, PCs 20 to 21 for each user, a DP server 69, an access right server 71, and an MFP 11.

  First, the first embodiment is different from the first embodiment in the first embodiment. The portable image display device 1 is mounted on a shared MFP 11 to charge, receive a document, transfer a document, and print. In contrast to the transmission of a document, in the present embodiment, it is mounted on a dedicated cradle 64 to charge, receive a document, and transmit a transfer document or a printed document.

  The configuration of the first embodiment has an advantage that document data read by the installed MFP 11 can be sent to the portable image display device 1, and document data sent from the portable image display device 1 can be printed as it is by the MFP 11. However, the configuration of the present embodiment has an advantage that the cradle can be placed on the desktop or can be held in each home because the cradle is small and cheap.

  The cradle 64 of the present embodiment includes a DP-I / F 65 that is an I / F with the cradle-I / F 61 provided in the portable image display device 1 and an N / F that is an I / F with the network 19. This is a simple configuration having only the W-I / F 66, the control unit 67, the power supply unit 68, and the like.

  In the first embodiment, the document data to be held in the portable image display device 1 is once held in the DP spool area 16 in the specific MFP 11 and transmitted to the portable image display device 1. In the case of the present embodiment, it is configured to be held in the DP spool area 70 in the shared DP server 69 on the network 19.

  In the configuration of the first embodiment, since there is no need to access an external server, there is an advantage that it can be used even in an environment where the server cannot be accessed, and the processing is fast. The acquisition method has an advantage that each document can be acquired via an arbitrary cradle on the network 19.

  Next, the first difference from the first embodiment is that the contact IC card 9 and the contact IC card reader / writer 8 are used in the first embodiment. In this embodiment, personalized data is obtained using a non-contact wireless IC card 63 and a wireless IC card reader / writer 62.

  The second difference from the first embodiment is that the contact type as in the first embodiment has an advantage that the cost is low and there is no interference that can be in the radio system. In such a wireless system, the IC card 9 can be moved closer to the vicinity of the IC card reader 62 instead of being attached to the IC card reader 8, and the non-contact type IC card 63 is used. There is an advantage that it is difficult to break, and an advantage that the problem of forgetting the IC card 63 attached to the portable image display device 1 is eliminated.

  In the present embodiment, the radio wave type IC card 63 is used, but any device capable of exchanging personalized data without contact may be used. For example, a mobile phone, PHS, PDA, etc. may be used. Infrared communication method may be used.

  Next, the third difference from the first embodiment is that, in the first embodiment, only the mail address described in the personalized data in the IC card 9 is automatically used as the transfer destination. On the other hand, the present embodiment is configured such that, on a screen (not shown), the instruction unit / additional data input unit / destination input unit 4 allows the operator to input the transfer destination.

  In the configuration of the first embodiment, since the e-mail is sent only to the e-mail address described in the personalized data, there is an advantage that the degree of security is high. In the configuration of the present embodiment, for example, information is sent to an acquaintance. There is an advantage that freedom of use increases.

  Next, the fourth difference from the first embodiment is that, in the first embodiment, the access permission information of each document is held in advance in the multiple document holding unit 5 in the portable image display device 1. On the other hand, in the present embodiment, the access permission information 72 of each document is acquired from the access right server 71 on the network 19 and used.

  Since the method as in the first embodiment does not need to access an external server, it can be used even in an environment where the external server cannot be accessed, and there is an advantage that the processing is fast. On the other hand, the method of accessing the access right server 71 as in the present embodiment has an advantage that the access right to each document can be centrally managed.

  For example, when it is desired to change the access right of a certain document, it can be changed immediately by only changing the access right on the access right server 71. Incidentally, in the present embodiment, since the access permission information of each document is once copied to the plural document holding unit 5, it can be used even in an environment where the server cannot be accessed.

  Next, the fifth embodiment differs from the first embodiment in that in the first embodiment, the access permission information of each document indicates permission or non-permission for each document. On the other hand, in this embodiment, permission or non-permission is instructed for each element of each document.

  Here, each element of each document refers to display document data, original document data, location data (such as URL) of the original document, additional data, and the like that constitute each document. The configuration of the first embodiment has the advantage that the access permission information can be simplified, but the configuration of the present embodiment has the advantage that the access permission can be specified precisely.

  Next, the sixth difference from the first embodiment is that in this embodiment, in addition to the access permission information of each document, the expiration date information of each document is also included. As a result, there is an advantage that old information that has passed the deadline need not be circulated and is not confused.

Next, the seventh difference from the first embodiment is that in the first embodiment, the original document data is transmitted when the transfer is instructed in the first embodiment. The URL of the original document is sent. In the configuration of the first embodiment, since the original document data is sent as it is, there is an advantage that it can be used as it is on the receiving side, but in the configuration of the present embodiment,
(1) The transfer size can be reduced by sending the URL of the original document instead of the original document data.
(2) When a person who receives the URL of the original document accesses the URL, by performing user authentication, finer access control than sending the original document as it is can be performed.
(3) Even when the original document is updated, if the document placed at the location specified by the URL is updated, the person who received the URL of the original document can access the latest document. is there.

  Next, the eighth difference from the first embodiment is that printing is performed by the MFP 11 to which the portable image display device 1 is attached in the first embodiment. In this case, printing is performed by the external MFP 11 via the cradle 64 and the network 19. In this case, the printing document data is transmitted to the MFP 11 in the same manner as the transfer document data is transmitted to each PC.

FIG. 15 is a diagram for explaining element information of each document held in the multiple document holding unit 5 in the second embodiment, and corresponds to FIG. 6 in the first embodiment.
The difference from the first embodiment is that the display document data of L403 and the additional data of L406 are both held in the PDF format. Keeping both in a common format makes it easier to synthesize them.

  Next, in the first embodiment, transfer permission information is held for each document. However, in this embodiment, transfer permission information is stored for each element constituting a document as in L409 to L412. keeping. First, L409 is transfer permission information for display document data. In the case of L409, it indicates that everyone is permitted.

  Next, L410 is the transfer permission information of the original document data, and in the case of L410, it indicates that it is not permitted to everyone. L411 is transfer permission information of the original document URL. L412 is the additional permission data transfer permission information, and in the case of L412, it indicates that transmission to only the mail address of the operator is permitted.

  Next, in the present embodiment, as in L413, it also has expiration date information of each document. Next, in the present embodiment, as in L414, the DP / ID of the portable image display apparatus that is permitted to perform various operations on each document is also provided.

  This information is checked at the time of the processing of step S504 in FIG. 13 together with the display permission information, and the corresponding document is displayed only on the permitted portable image display device. As a result, when the document is sent to the wrong portable image display device, it is not displayed, and neither the print instruction nor the transfer instruction can be performed, and there is an advantage that the security strength can be increased.

  In the present embodiment, for each document, various operations are collectively permitted / disallowed for each DP, but may be permitted / not permitted for each operation type. In addition, for each document, various operations may be permitted / not permitted for each type for each cradle. Thereby, for example, specific document data can be acquired via an arbitrary cradle, but transmission of specific original document data and printing of document data can be performed only via a specific cradle.

FIG. 16 is a diagram for explaining composition of display document data, additional write data, and an original document URL.
In the first embodiment, the display document data and the postscript data are separately sent to the MFP 11 and each user's PC, and both are combined and printed by the MFP 11, or both are combined by each user's PC. In the case of the present embodiment, the display document data, the additional recording data, and the original document URL are combined into one image and sent to each user's PC or MFP 11.

  In the configuration of the first embodiment, there is an advantage that the composition processing in the portable image display device 1 is not necessary. However, in the configuration of the present embodiment, since there is one transfer image, handling is easy. In addition, there is an advantage that the composition processing on the PC side or MFP 11 side of each user is unnecessary.

  In the present embodiment, as shown in FIG. 16, display image data 81 is used as a base image, and additionally recorded data 82 and original document location data (URL) 83 are combined thereon to form a single image. Will be sent.

  As shown in FIG. 16, the display document data, the additional data, and the original document URL, which are each element constituting one document, are held independently, and are combined at the time of display or transfer, so that There is an advantage that each of these elements can be updated independently, compared to the method of combining and holding the above. For example, when the location of the original document URL changes, it is only necessary to change the original document URL data.

  FIG. 17 is a flowchart of the transfer data sending process of the portable image display device according to the second embodiment, and corresponds to the flowchart of FIG. 12 according to the first embodiment. In FIG. 12, the original document data and the additional record data, or the display document data and the additional record data are sent separately, but in FIG. 17, the various document elements are combined and sent.

  First, in step S601, the display document data is set as transfer document data. Next, in step S602, it is checked with the additional data transfer permission information described with reference to FIG. 15 whether or not the transfer of additional data is permitted. If the transfer of additional data is permitted, the transfer document is transferred. The additional data is combined with the data.

  Next, in step S603, it is checked whether or not the original document URL exists in the corresponding document, and whether or not the transfer of the original document URL is permitted is checked by the original document URL transfer permission information described with reference to FIG. . Further, it is also checked whether each document described in FIG. 15 is within the expiration date. If all documents are OK, the original document URL is combined with the transfer document data in step S604.

  As a result, as the transfer document data, a composite image is generated by combining the display document data, the additional recording data, and the original document URL as described with reference to FIG. On the other hand, if any of the checks is NG in step S603, it is checked in step S605 with the display document data transfer permission information described with reference to FIG. 15 whether transfer of display document data is permitted. Further, it is also checked whether each document explained in FIG. 15 is within the expiration date. If all documents are OK, the process proceeds to step S606. In this case, as the transfer document data, a composite image is generated by combining the display document data and the additional recording data as described with reference to FIG.

  On the other hand, if any of the checks in step S605 is NG, the process proceeds to step S607 and no transfer process is performed.

  In step S606, the transfer document data and the destination information are transmitted to the cradle, and a request is made to send the transfer document data to the e-mail address specified by the destination information. In the case of the present embodiment, as destination information, a destination mail address arbitrarily input by an operator on a screen (not shown) is used.

  Therefore, in the case of the present embodiment, the transfer permission check in step S602, step S603, or step S605 is performed on the destination email address input by the operator.

  In this way, only authorized users can inspect and transfer each document, and only authorized users can receive the transferred document. Thereby, not only the access right check for each transfer sender but also the access right check for each transfer receiver can be performed.

  Next, in step S607, it is checked whether or not the processing has been completed for all the documents. If the processing has not been completed, the processing returns to step S601 for the document for which the next transfer instruction has been issued.

  In FIG. 17, when sending the original document URL, the display document data and the original document URL are combined and sent, but only the original document URL may be sent.

(Third embodiment)
The third embodiment of the present invention differs from the first embodiment in the mounting destination of the portable image display device 1, the personalized data acquisition method, the transmission element selection method, the access log function, Only the location information recognition function is different. For this reason, only a difference part is demonstrated.

  FIG. 18 is a block diagram of a document circulation system including the portable image display device 1 according to the third embodiment. This document circulation system includes a portable image display device 1, a network 19, PCs 20 to 21 of each user, a DP server 69, a personalization server 95, an access log server 97, an MFP 11, and other portable images. It comprises a display device 99 and a wireless location notification device 92.

  In the present embodiment, the first difference from the first embodiment is that in the first embodiment, each document data is transferred to the PCs 20 to 21 of each user via the MFP 11. In contrast, in the present embodiment, the portable image display device 1 itself has a wireless LAN-I / F 94 and is configured to directly transfer each document data to each user's PC. It is.

  In the configuration of the first embodiment, the portable image display device 1 does not wait for the LAN-I / F, so that the cost is low and light, and the original document data is transmitted only through a specific MFP 11 or cradle. There is an advantage that the security level is high because cannot be performed. In contrast, the configuration of the present embodiment has an advantage that convenience is improved because the original document data can be sent without the MFP 11 and the cradle 64.

  Next, the second difference from the first embodiment is that personalized data for each operator is obtained from the IC card 9 in the first embodiment, whereas in this embodiment, the personalized data for each operator is obtained. The personalized data 96 for each operator is obtained from the personalized server 95 on the network 19.

  Specifically, when the operator inputs a user ID on the screen (not shown) of the portable image display apparatus 1, the portable image display apparatus 1 sends the user ID to the personalization server 95. The personalization data 96 corresponding to the sent User ID is obtained from the personalization server 95.

  The method of obtaining personalized data for each operator from the IC card 9 as in the first embodiment has the advantage that a personalization server is not required and that it can be used without being connected to the personalization server.

  On the other hand, the method of obtaining personalized data for each operator from the personalized server 95 as in the present embodiment has the advantage that the size of the personalized data is not limited by the storage size of the IC card 9 and each operator. There are advantages that different personalized data can be centrally managed by the personalization server 95 and that the IC card 9 is not required to be carried. In the case of the present embodiment, since the portable image display device 1 has the wireless LAN-I / F 94, the personalization server 95 can be always accessed.

  Other portable image display devices 99 exist on the network 19, and these devices also use the personalization server 95 in the same manner as the portable image display device 1 to use personalized data used in these devices. To get.

  Next, the third difference from the first embodiment is that, in the first embodiment, when transmitting a document, it is possible to specify which element is to be transmitted among a plurality of elements constituting the document. Instead, the elements to be transmitted were automatically determined. On the other hand, in the present embodiment, the operator can specify which element is to be transmitted using a screen (not shown) and the instruction unit 4. In the configuration of the first embodiment, there is an advantage that it is possible to save time and effort to specify an element to be transmitted, but in the configuration of the present embodiment, there is an advantage that it is possible to precisely specify which element is transmitted.

  Next, the fourth difference from the first embodiment is that, in this embodiment, an access log is displayed when a document is displayed, transferred, or printed using the portable image display device 1. This is the point that the access log server 97 records.

  In this way, it is possible to determine who has viewed the circulation, and it is possible to easily check whether the circulation is delayed. In addition, there is an advantage that the degree of security is increased because records such as who viewed what documents, who printed them, and who sent the original document data remain.

  Next, the fourth difference from the first embodiment is that the portable image display device 1 has a location information recognition function in the present embodiment. First, in each place where the portable image display device 1 may be used, a wireless location notification device 92 is arranged.

  The wireless location notification device 92 has unique location ID information 93 therein, and sends the location ID information 93 wirelessly so as to reach the area in charge. The portable image display device 1 has a wireless location recognition unit 91, and by recognizing the location ID sent from the location notification device 92, the portable image display device 1 is currently in which location. You can recognize whether it is used in a place.

  This location ID is collated with an accessible location ID (not shown) described in the access permission information in the portable image display device, and is used to disable various operations outside the accessible location.

  Thereby, for example, even if the portable image display device 1 is stolen and the contents of the portable image display device 1 are not seen at a place other than a predetermined place, there is an advantage that the degree of security is increased. The acquired location ID is also used to record location information when the operator performs each operation in the above-described access log. Accordingly, there are advantages that the current position of the portable image display device can be grasped, the staying status of the circulation processing can be grasped, and the security level is increased.

    Next, the fifth difference from the first embodiment is that printing is performed by the MFP 11 to which the portable image display device 1 is attached in the first embodiment. In this case, the print document data is directly sent to the external MFP 11 via the network 19 for printing.

  FIG. 19 is a flowchart of the transfer data sending process of the portable image display device 1 in the third embodiment, and corresponds to the flowchart of FIG. 12 in the first embodiment. In FIG. 12, when transmitting a document, it is not possible to specify which element is to be transmitted among a plurality of elements constituting the document, and the element to be transmitted is automatically determined. On the other hand, in FIG. 19, the operator can specify which element is to be transmitted using a screen (not shown) and the instruction unit 4, and the transfer document is determined accordingly. Different.

  As shown in FIG. 19, first, in step S701, transfer of display document data is instructed, and transfer of display document data is permitted in the display document data transfer permission information described in FIG. If so, display document data is set as transfer document data. Otherwise, blank paper data is set as transfer document data.

  Next, in step S702, when transfer of additional data is instructed and transfer of additional data is permitted in the additional data transfer permission information described with reference to FIG. 15, the additional data is synthesized with the transfer document data. To do.

  Next, in step S703, when the transfer of the original document URL is instructed and the transfer of the original document URL is permitted in the original document URL transfer permission information described with reference to FIG. Synthesize the document URL. As a result, as the transfer document data, a composite image obtained by combining the display document data, the postscript data, and the original document URL, or a subset thereof, as described in FIG. 16 is created.

  Next, in step S704, it is checked whether or not the transfer document data is blank data. Further, the expiration date of the corresponding document is also checked. If it is NG, transfer is not performed, and the process proceeds to step S707. On the other hand, if the result of the check in step S704 is OK, the transfer document is directly sent by e-mail to the designated destination in step S705.

  Next, in step S706, the access log server 97 is provided with transmission destination information, transmission document ID, transmitted document element type information, transmission date and time, transmitted DP / ID of the portable image display device, location ID information at the time of transmission, The User ID of the user who has operated the portable image display device at the time of transmission is transmitted.

  Next, in step S707, it is checked whether or not the processing has been completed for all the documents. If the processing has not been completed, the processing returns to step S701 for the document for which the next transfer instruction has been issued.

  Although the transfer process has been described with reference to FIG. 19, various types of data are sent to the access log server 97 in the same manner as in step S <b> 706 also when the print process or the browse process is performed.

  In this embodiment, the transfer is performed and then recorded in the access log server 97. However, the transfer may be performed after the transfer is sent to the access log server 97. The former has the advantage that the transfer can be started earlier, while the latter has the advantage that the security strength is increased.

  Furthermore, it is possible to confirm whether or not the log has normally arrived at the access log server, and when the log has not arrived normally, the configuration is such that the transfer is not performed, thereby further increasing the security strength. is there.

  In this embodiment, the operator is allowed to input the User ID. However, the identification information of the operator may be obtained by bio-authentication means such as fingerprint authentication. In this embodiment, both transmission and reception of document data are performed via the wireless LAN. However, either of these may be performed via the MFP 11 or the cradle 64.

  For example, by sending document data via the MFP 11 or cradle 64, the sending operation of the original document data can be performed only at a specific location, and the security strength is improved. On the other hand, there is an advantage that the original document data, the original document URL, and various permission information can be updated in real time by transmitting the document data via the wireless LAN.

(Fourth embodiment)
The fourth embodiment of the present invention differs from the first embodiment only in the interface method between the portable image display device 1 and the MFP 11. For this reason, only a difference part is demonstrated.
First, in the first embodiment, the interface between the portable image display apparatus 1 and the MFP 11 is taken by electronic communication means such as the signal line 22, whereas in the present embodiment, optical means is used. The difference is that it takes an interface.

  FIG. 20 summarizes the transfer document reception process in step S107 for explaining the process performed on the MFP 11 side in FIG. 9 in the first embodiment and the transfer document transmission process on the portable image display apparatus 1 side in FIG. FIG.

  First, in step S801, the operator instructs the portable image display device 1 to transfer to the MFP 11, and the portable image display device 1 displays the document data for display, additional data, and the original document URL of the designated document. The destination and the document ID are combined and displayed on the screen display unit 6.

  This display image is, for example, an image in which the destination mail address and the document ID are added to the lower part of the image in FIG. The operator places the portable image display device 1 on which these images are displayed on the document table of the MFP 11 in the same manner as normal paper.

  Next, in step S802, the MFP 11 is instructed to perform a “transfer from portable image display device” operation, and the MFP 11 displays the display document data and additional data displayed on the portable image display device placed on the document table. The original document URL, the destination, and the document ID are optically scanned and captured.

  In step S803, the MFP 11 analyzes the scanned image and extracts destination information and a document ID. In step S <b> 804, the MFP 11 acquires transfer permission information from the access right server 71 for the extracted document ID.

  Next, in step S805, it is checked whether transfer to the extracted destination is permitted based on the acquired transfer permission information. If NG, the transfer is not performed. On the other hand, in the case of OK, in step S806, the scanned and captured image is mailed to the extracted destination.

Further, as in the present embodiment, checking the transfer permission information on the MFP 11 side has an advantage that it is not necessary to perform the check on each portable image display device.

  In the present embodiment, the original document URL, the destination, and the document ID are visually combined with the display document data and displayed. This is displayed by human eyes using a watermark image embedding technique. May be embedded in the display image in a state where it cannot be identified. The former has the advantage that the processing is simple, and the latter has the advantage that the receiver cannot see unnecessary information.

  In the present embodiment, the optically scanned display image is sent by e-mail. If the MFP 11 can acquire the original document data based on the received original document URL, the scanned image is scanned. The original document data may be transmitted instead of the displayed image.

  In each of the above embodiments, the portable image display device uses the electrophoretic display means, but may use a liquid crystal display means. The liquid crystal display means consumes less power than the electrophoretic display means, and is disadvantageous in terms of weight and price. However, the liquid crystal display means may be used to constitute the embodiment of the present invention. There is no problem.

  In each of the above-described embodiments, only one type of original document data or original document URL is transferred for each document. You may make it send one.

  For example, for a single document, it has multiple original document data and original document URLs such as Japanese and English, color and black and white, large character and small character, each application format and PDF. The original document data to be sent and the original document URL are switched according to the orientation information in the personalized data.

  In each of the above-described embodiments, the paper shared circulation has been electronically described.
