[0001]
BACKGROUND OF THE INVENTION
  The present invention provides a facsimile machine and the like.Communication deviceRegarding ITU-T TT. The present invention relates to a device that can perform confidential communication by specifying a box with an F code specified by a command according to the 30 recommendation.
[0002]
[Prior art]
  Current,Communication deviceITU-T TT. So that it can communicate normally between devices of different manufacturers and models. In general, a facsimile communication procedure based on the 30 recommendation is executed. In the 30 recommendation, a sub-address signal (SUB) used for confidential communication, a selective polling signal (SEP) used for selective polling, a password signal (PWD) used for both, a transmission side identification signal (SID (Sending ID: when using SUB) The bit on DIS / DTC / DCS during communication is the same bit number “50” as PWD)).
[0003]
  This kindCommunication deviceIn particular, for facsimile machines, the ITU-T TT. The image data received at the called side is stored in a box designated by the SUB from the calling side (for example, an image memory area managed in units of boxes) by using the extension field of the 30 recommendation. Only when the set password is entered, the confidential communication function that prints out the image data from the box, or the image data is stored in advance in a plurality of boxes on the called side. Provided with a selective polling communication function in which a called party searches for a box that matches the SEP by notifying the SEP of a box that stores desired image data, and transmits the image data of the corresponding box to the calling party There is.
[0004]
  In the communication machinery industry association, by considering applications related to confidential transmission using SUB and (selection) polling reception using SEP, it is possible to communicate normally between devices of different manufacturers and models. ITU-T TT. An F code that designates the box by a command according to the 30 recommendation is adopted, and a confidential box, a bulletin board, and a relay box, in which the concept of the box (hereinafter also referred to as a box) is expanded, are presented. Facsimile machines equipped with this F-code functionCommunication deviceAre classified into an F-code compatible center machine having a box and an F-code compatible machine having a function of transmitting to the box (F-code transmission) and a function of extracting box information (F-code extraction).
[0005]
This F code is an ITU-T TT. It shows the function to realize data communication through the box by the extended part (extended field) of 30 Recommendations, SUB, SEP, etc. can be set using this extended part, and it is a manufacturer matter for PWD and SID The operation of the box (system memory management area) is left to the receiving side.
[0006]
For example, by registering a delivery destination in a SUB receiving box, a relay broadcast transmission function in which a receiver transmits to the delivery destination after reception can be realized. In this case, the transmission side designates a desired reception box by SUB, and further designates a personal identification number by SID as necessary. On the other hand, the receiving (relay) side holds the image data (document) in the image memory and transfers it to the delivery destination in the relay box. Further, when a receiving side (confidential box) is designated by the SUB, the receiving side can print out the document by receiving document printing after reception. The transmitter may perform the same procedure as that for SUB confidential even when the relay function is realized. It is assumed that a plurality of boxes can be opened on the receiving side. For example, a bulletin board can designate a desired bulletin board only by SEP regardless of use / non-use of PWD (personal identification number).
[0007]
In addition, what is related as this type of apparatus is described in Japanese Patent Laid-Open Nos. 06-334883 and 06-350830.
[0008]

DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, the present invention will be described with reference to the drawings. 1 to 6 relate to the present invention.Communication deviceIt is a figure which shows an example of the facsimile apparatus to which 1st Embodiment of this is applied.
[0026]
In FIG. 1, a facsimile apparatus 10 stores parameters necessary for control, registration data by user input, and the like in a system control unit 11 and irradiates a document at a reading position with a system memory 12 used as a work area. A scanner 13 that reads image information to be transmitted or copied by reflected light from the image surface at a predetermined resolution, and received or read image information and various reports (for example, a communication management report and various registration lists) are recorded on a recording sheet. A plotter 14 that records and outputs at a predetermined resolution; a network control device 15 that has an automatic outgoing / incoming function for connecting or disconnecting a line by executing a predetermined line control when making or receiving a call by being connected to a public telephone line; G3 FAX modem 16 that modulates and demodulates image information to be transmitted and various procedure signals, read image information to be transmitted and received reception The image memory 17 temporarily stores the image information in a compressed state, and the read image information is compressed and output by a known encoding method, while the read image information and the received image information in the compressed state are decoded and the original image information is compressed. An encoding / decoding unit 18 that reproduces (expands) and outputs the image information; an operation display unit 19 that includes a display LCD, an LED, and operation keys; Are connected via a bus 20, and the system control unit 11 performs overall control according to a control program stored in advance, thereby operating as a facsimile machine having an F-code function to be described later while executing the present invention. To do.
[0027]
Here, the facsimile machine 10 stores a box for storing communication information such as a confidential box, a bulletin board, a relay box, etc. presented by the communication machine industry association (for example, a memory area for storing and managing image information in units of boxes). ITU-T TT. By searching and specifying with the F code specified by a command such as SUB using an extension field according to the 30 recommendation, the type (54) of the box stored in the box is known, confidential transmission, selective polling reception, and relay broadcast transmission Are provided with an F-code function that can be normally performed between devices of different manufacturers and models, and has a function of transmitting to this box (F-code transmission) and a function of extracting information on the box (F-code extracting) (F It can also operate as a code-compatible machine) and is configured as an F-code compatible center machine that opens these boxes themselves.
[0028]
The facsimile apparatus 10 is configured such that the system control unit 11 can open a plurality of types of boxes such as a confidential box, a bulletin board, and a relay box. Each box information is shown in FIG. As described above, it is stored in the system memory 12 and managed. For example, the box attribute (50) stores and manages whether the box is used. The F code (51) is used when accessing by specifying a box. For example, when a SUB is received, a box having an F code that matches the SUB is searched or a SUB confidential received document is printed. Similarly, it is generally used when searching for a box having an F code input by a user. The password (52) is used as a secret key for each box. The box name (53) is a name given to each box, and can be used by, for example, putting a personal name when using a confidential box for personal purposes. The box type (54) indicates the above-mentioned confidential box or bulletin board box, and is usually determined when a box is opened. As shown in FIG. 3, the box-specific information (58) includes a self-transfer destination (581) for a confidential box, a holding condition (582) for a bulletin board box, and distribution destinations 1 to N (583-1 to 583) for a relay box. n), which is unique information for each box type. It is assumed that each box is identified by an identifier (this is referred to as a box ID) indicating what number is physically located.
[0029]
Then, the system control unit 11 opens, changes, or deletes the box according to the input instruction from the operation display unit 19 or the instruction such as reception of the communication information via the communication line, and stores the communication information stored in the box. An input screen for setting / designating the F code is displayed on the operation display unit 19 by a specific operation instructing use of the F code function. As the F code, a maximum of 20 digits can be input and set among “number”, “*”, “#”, and “space”.
[0030]
For example, in the case of opening a confidential box, as shown in FIG. 4, an operation for instructing the setting of the F code function first determines whether the setting is a confidential box, a bulletin board, or a relay box of the F code function. The menu screen to be selected is displayed (FIG. 4A). When a confidential box is selected by inputting “1”, the menu screen of the confidential box is displayed (FIG. 4B), and “1” is input. When opening / changing / deleting a box is selected, an F-code input screen for designating a box is displayed (FIG. 4C), and an F-code for specifying a confidential box to be opened is input. When the “SET” key is input, an input screen for inputting the name of the box is displayed (FIG. 4D). For example, “Takoyaki Box” is input as the name of the confidential box to be opened, and the “SET” key is pressed. input Displays an input screen for selecting and entering a password to be added to the box together with the box name (FIG. 4 (e)). When the “password” selection key is entered, a password for permitting use of the box is displayed. The input screen is displayed (FIG. 4 (f)). Subsequently, input related to the box to be opened is continued, and after inputting the minimum necessary items, the “Register” key is selected on the input screen of FIG. 4 (e). Thus, a box in which the box information shown in FIG. 2 is stored and managed in the system memory 12 is opened. It should be noted that the box may not be changed, and it is needless to say that there is no problem even if the opening and closing of the box are different menus. Although not shown, it is assumed that the destination to which the received document is transferred can be input by selecting the transfer destination in FIG.
[0031]
Also, when printing a document (image information) in a confidential box, as shown in FIG. 5, an operation for instructing the setting of the F code function is performed, and first, the confidential box, bulletin board, and relay box of the F code function are displayed. A menu screen for selecting which setting is displayed (FIG. 5A). When a confidential box is selected by inputting “1”, the confidential box menu screen is displayed (FIG. 5B). ) When document printing is selected by inputting “3”, an F-code input screen for designating a box is displayed (FIG. 5C), and an F-code for specifying a confidential box for document printing is displayed. When a “set” key is input and a box that matches the specified F-code is searched and specified, and the corresponding box stores image information (communication information), a password can be used if necessary. After input Displays the number of documents to be stored with the box name (FIG. 5 (d)), the input of the "start" key, to start recording the output by the plotter 14 to print a document to be stored. At this time, if the corresponding box is not searched, for example, “There is no corresponding box” is displayed, and if there is no document even if there is a corresponding box, “0 document” is displayed. Show it.
[0032]
At this time, when searching for a box that matches the designated F code, the system control unit 11 starts the search after the F code is input and set as shown in the flowchart of FIG. First, it is confirmed that the box indicated by the pointer P is valid (step P21), and the box of the type of the F code function instructed to be input is set. When the type of the box matches (step P31), the F code of the box is compared with the input F code (step P41). If the box is invalid or the box type does not match, The pointer P is used as the ID of the next box as it is (step P51), and if there is a box with that ID (step P). 1), the process returns to step P21, and continues the similar search process. Therefore, comparison of F codes of different types of boxes can be skipped, and it is not necessary to compare F codes for all boxes, reducing the search burden of boxes specified by a maximum of 20 digits of F codes. Can do.
[0033]
Then, when the box is valid and the type matches, if the F code of the compared box does not match the input designated F code (step P41), the pointer P is similarly set as the ID of the next box (step P51). ) If there is a box with that ID (step P61), the process returns to step P21 and the same search process is continued. If there is no box to be searched, a box with the same F code is not confirmed. (Step P61) The input F code sets a history of rejected input, and displays a screen for rejecting input on the operation display unit 19 because there is no corresponding box (Step P71). When an F code box that matches the code is confirmed (step P41), an input permission history is set. Both allows you to continue the operation to display the following screen on the operation display unit 19 (step P81). For example, if there is a document in a box with the same F code, a start key (not shown) is pressed and printed.
[0034]
As described above, in the present embodiment, even when a plurality of various types of boxes such as confidentials and bulletin boards are opened, only the F code of the box with the same type of the designated confidential is designated as the input designated F code. It is possible to compare, and it is possible to avoid wastefully comparing the F codes of boxes of different types. Accordingly, the search time for the designated box can be greatly shortened, the box designated by the F code can be quickly searched and specified, the communication information to be stored is taken out, for example, the confidential document printing process can be performed at high speed ( Comfortable).
[0035]
  Next, FIGS. 7 to 9 relate to the present invention.Communication deviceIt is a figure which shows an example of the facsimile apparatus to which 2nd Embodiment of this is applied. Since the present embodiment is configured in the same manner as the above-described embodiment, the same reference numerals are given to the same configuration by using the drawings (the same applies to the other embodiments described below). ).
[0036]
In FIG. 1, the facsimile apparatus 10 stores, as box information, box attributes (50), F codes (51), and passwords (52) in the system memory 12 used by the system control unit 11, as shown in FIG. , Box name (53), box type (54), next box ID (57), and box-specific information (58) are stored and managed. In this embodiment, as shown in FIG. 57) stores the ID of the box of the same type in the next box ID so that a confirmation can be made sequentially from the top for each box of the same type by establishing a link between the boxes of the same type. It is like that.
[0037]
Specifically, when opening the box, the system control unit 11 acquires the ID of the empty box (step P111) and confirms the empty capacity of the image memory area as shown in the flowchart of FIG. In step P121), if there is no space to open the box, the box cannot be opened, and a message such as “no empty box” is displayed on the operation display unit 19 or an alarm is sounded to notify that there is no space. Error processing is performed (step P131), and this processing is terminated. If there is a vacancy, box information such as an F code is stored in the system memory 12 (step P141), and a box of the same type such as confidential is matched. Is read as a pointer P (step P151), and the box ID is “EOF (not applicable = end). (Step P161), for example, as shown in FIG. 7, the pointer P is sequentially advanced from “n” at the top (1st) of the confidential box to “m” and “e” of the next box ID. In (Step P171), when it is confirmed that there is no next box linked with the box ID “EOF” (Step P161), the “EOF” is rewritten with the ID of the empty box acquired in Step P111. At the same time, “EOF” is written in the next box ID of the box to update the link attached to the same type (step P181).
[0038]
When the system control unit 11 searches for a box that matches the designated F code, as shown in the flowchart of FIG. 9, when the F code is input and set to start the search, the system control unit 11 searches for the box. As the first box ID whose type coincides with the F code function instructed to be input (step P12), unless the next box ID is “EOF” and has not been opened (step P22), the box information indicated by the pointer P is When reading (step P32) and the F code of the box does not match the input F code (step P41), the pointer P is directly used as the ID of the next linked box (step P51), and the step P22 is performed. Returning to step 2, the same processing is repeated, and the next box ID is “EOF” and the same type of box is not opened. (Step P22), a screen for rejecting input is displayed on the operation display unit 19 because there is no corresponding box (Step P71), while an F code box that matches the F code specified for input is confirmed. (Step P41), the next screen is displayed on the operation display unit 19 to permit the input to be continued (Step P81). Therefore, after confirming the type of the first box, it is possible to skip the comparison of F codes of different types of boxes by simply reading the next box ID linked without checking the box type. It is possible to reduce a burden caused by searching for a box designated by an F code having a maximum of 20 digits.
[0039]
As described above, in the present embodiment, in addition to the operational effects of the above-described embodiment, input setting (designation) is performed simply by sequentially reading the F code of the box whose type matches the F code function according to the link by the next box ID. The search time for the designated box can be greatly reduced by omitting the confirmation of the box type. Therefore, desired communication information can be taken out of the box more quickly, and processing by the F code function can be performed at high speed (comfortable).
[0040]
  Next, FIGS. 10 and 11 relate to the present invention.Communication deviceIt is a figure which shows an example of the facsimile apparatus to which 3rd Embodiment of this is applied.
[0041]
As shown in FIG. 2, the facsimile apparatus 10 includes a box attribute (50), an F code (51), and a password (52) as box information in the system memory 12 used by the system control unit 11. The box name (53), the box type (54), the next box ID (57), and the box-specific information (58) are stored and managed, and the next box ID (57) is shown in FIG. As shown in the figure, the next box ID stores the ID of the same type of box so that confirmation can be performed sequentially from the top for each box of the same type by establishing a link between the same type of boxes. It has become.
[0042]
Specifically, when the system control unit 11 opens a box, as shown in the flowchart of FIG. 10, after acquiring an empty box ID and confirming the empty box (steps P111, P121, and P131), the system control unit 11 sets the box information. While storing in the system memory 12 (step P141), the top ID of a box with a matching type such as confidential is read out as a pointer P (step P151), and the ID of the next box becomes “EOF” (step P161). ) Check whether the F code set to be input is smaller than the F code in the box indicated by the pointer P (step P162). If the F code set to input is not small, the pointer P is rewritten and held as the pointer Q. And the pointer P is linked as a box of the same type (Step P171), the process returns to Step P161 and the same processing is continued, and when the F code set to be input is small, that is, when the F code box larger than the input set F code is confirmed, Rewrite the next box ID of the box indicated by the pointer Q to the acquired newID, and write the ID of the box indicated by the pointer P to the next box ID of the box of the newID, and link the same type so that the box IDs are in ascending order. On the other hand, when the box ID is “EOF” and it is confirmed that the input F code is larger than the F codes of all the boxes linked as the same type (step P161). ), The empty box acquired in step P111 for that “EOF”. Rewrites to the scan of ID, the next box ID of the box to update the link box ID is written "EOF" is stretched to the same species to be in ascending order (step P181).
[0043]
When the system control unit 11 searches for a box that matches the designated F code, as shown in the flowchart of FIG. 11, when the search is started according to the F code input setting, the F code instructed to be input is entered. The first box ID whose type matches the function is set as a pointer P (step P12), and the box information indicated by the pointer P is read (step P32) unless the next box ID is “EOF” (step P22). Until the F code matches the input F code (step P41), the pointer P is advanced to the next linked box ID (step P51), and the same processing is repeated to match the input specified F code. When the F code box to be checked is confirmed (step P41), the next screen is displayed on the operation display unit 19. Although the input is permitted (step P81), when the next box ID is “EOF” and the same type of box is not established (step P22), the next box ID is not “EOF”, but the input When the designated F code is smaller than the F code of the box indicated by the pointer P, that is, smaller than the F code of the box linked in the ascending order of the F code of the same type (step P33), it is input that there is no corresponding box. Is displayed on the operation display unit 19 (step P71). Therefore, after confirming the F code larger than the input F code, the F code of the next box linked in ascending order of the F code is large. Skipping (cancellation of search) can be performed, and the burden caused by searching for a box specified by a maximum 20-digit F code can be reduced.
[0044]
As described above, in the present embodiment, in addition to the operational effects of the above-described embodiment, the F code that is designated to be input is sequentially only when it is not smaller than the F code of the box indicated by the pointer P whose type matches the F code function. When the F code in the box indicated by the pointer P exceeds the input designated F code (out of the range), the subsequent search can be canceled and the F code is compared unnecessarily. By avoiding this, the search time for the specified box can be greatly shortened. Therefore, desired communication information can be taken out of the box more quickly, and processing by the F code function can be performed at high speed (comfortable).
[0045]
  Next, FIGS. 12 and 13 relate to the present invention.Communication deviceIt is a figure which shows an example of the facsimile apparatus to which 4th Embodiment of this is applied.
[0046]
As shown in FIG. 12, the facsimile apparatus 10 includes a box attribute (50), an F code (51), and a password (52) as box information in the system memory 12 used by the system control unit 11. In addition to storing and managing the box name (53), box type (54), next box ID (57), and box-specific information (58), the number of digits of the input F code is calculated. As shown in FIG. 7, the next box ID (57) has a link between boxes of the same type as shown in FIG. The next box ID stores the ID of the same type of box so that the confirmation process or the like can be performed sequentially from the top for each same type of box.
[0047]
Then, when searching for a box that matches the designated F code, the system control unit 11 calculates and temporarily stores the number of digits of the designated F code as shown in the flowchart of FIG. When the search is started by the F code input setting, the first box ID whose type matches the F code function instructed to be input is set as a pointer P (step P12), and the next box ID is “EOF” and the same type of box. Is not established (step P22), a screen for rejecting input is displayed on the operation display unit 19 because there is no corresponding box (step P71), but unless the next box ID is “EOF” (step P22), The box information indicated by the pointer P is read (step P32), and the F code digit number of the box indicated by the pointer P is input and set. The pointer P is advanced to the linked next box ID (step P51) until the number of digits of the F code matches (step P34), the same processing is repeated by returning to step P22, and the number of digits of the F code is repeated. When the F codes do not match, it is checked whether the F code in the box indicated by the pointer P matches the input F code (step P41). If the F codes do not match, the next box to which the pointer P is similarly linked is checked. The process proceeds to ID (step P51), returns to step P22, and repeats the same processing. When an F code box that matches the input F code is confirmed (step P41), the next screen displays the operation display section. 19 is permitted to continue the input (step P81). Therefore, only when the number of digits is the same as the type of the F code function and the same number of digits as the input designated F code, the type or number of digits is checked by checking whether or not the F code itself matches. On the other hand, it is possible to skip the comparison of F codes in different boxes, eliminating the need to compare F codes for all boxes, and reducing the burden of searching for a box specified by a maximum 20-digit F code can do.

When the search is started by the F code input setting, the first box ID whose type matches the F code function instructed to be input is set as a pointer P (step P12), and the next box ID is “EOF” and the same type of box. Is not established (step P22), a screen for rejecting input is displayed on the operation display unit 19 because there is no corresponding box (step P71), but unless the next box ID is “EOF” (step P22), The box information indicated by the pointer P is read (step P32), and the F code SUM value of the box indicated by the pointer P is The pointer P is advanced to the next linked box ID (step P51) until it matches the SUM value of the F code that has been set (step P51), and the same processing is repeated by returning to step P22. Only when the SUM values match, it is checked whether the F code in the box indicated by the pointer P matches the input F code (step P41). If the F code does not match, the pointer P is linked similarly. The process proceeds to the next box ID (step P51), returns to step P22, and repeats the same processing. When an F code box that matches the input F code is confirmed (step P41), the next screen is operated. Displaying on the display unit 19 is permitted to continue the input (step P81). Therefore, only when the SUM value is the same as the type of the F code function and the same SUM value as the input designated F code, the type or SUM value is checked by checking whether or not the F code itself matches. On the other hand, it is possible to skip the comparison of F codes in different boxes, eliminating the need to compare F codes for all boxes, and reducing the burden of searching for a box specified by a maximum 20-digit F code can do.
