Further, the network facsimile apparatus FX directly exchanges data between the network control unit 7 and the G3 FAX modem 8.

  Next, the operation of this embodiment will be described. The network facsimile apparatus FX of the present embodiment acquires transmission history information at the time of transmission, stores it in the parameter memory 3 and visualizes it as necessary. Of the transmission history information for each transmission stored in the parameter memory 3, Then, an erasure process is performed to erase the transmission destination information for specifying the transmission destination, such as a transmission destination name, for all transmissions or arbitrary transmissions.

  That is, when the network facsimile apparatus FX performs facsimile communication, it acquires communication history information and stores it in the parameter memory 3 for each communication. For example, every time a facsimile transmission is performed, a communication date, a communication time, a destination name (transmission destination information), a communication mode, a communication time, the number of transmissions, a transmission result indicating whether transmission has been properly completed or an error, user The transmission history information such as the name (operator name) and the document number is acquired and stored in a predetermined area of the parameter memory 3.

  Then, the network facsimile apparatus FX reads the transmission history information from the parameter memory 3 at a predetermined time, and records and outputs it on a recording sheet with a plotter 6 as shown as a communication management report 20 in FIG. By displaying on the display of the operation display unit 13, it is converted into a specific format, attached to an e-mail, and sent to another network facsimile apparatus FX connected to the network NW via the LAN transmission control unit 9. To visualize.

  However, since the transmission history information includes confidential information such as a transmission destination as described above, there are cases where it is desired to delete the transmission history information.

  Therefore, in the network facsimile apparatus FX of the present embodiment, the transmission history information deletion operation is performed on the operation display unit 13 using the transmission history information deletion mode, thereby deleting the transmission history information intended by the user from the parameter memory 3. be able to.

  In other words, the network facsimile apparatus FX is set to the transmission history information erasing mode by the operation display unit 13 and when the transmission history information erasing operation is performed, the system control unit 1 performs all the transmissions stored in the parameter memory 3 for each transmission. Delete processing for deleting only the transmission destination information from the transmission history information.

  In this case, the system control unit 1 erases the transmission destination information by overwriting the transmission destination information storage area of each transmission history information in the parameter memory 3 with predetermined specific information, for example, “*” information. May be.

  Then, the system control unit 1 reads out the transmission history information from which the transmission destination information has been deleted from the parameter memory 3 at a predetermined time, and records and outputs it on the recording paper by the plotter 6 as shown as the communication management report 21 in FIG. In addition, by displaying on the display of the operation display unit 13, another network connected to the network NW via the LAN transmission control unit 9 after being converted into a specific format and attached to an e-mail It is visualized by sending it to the facsimile machine FX. FIG. 4 shows the communication management report 21 when the transmission destination information of the transmission history information is overwritten and deleted with the “*” information.

  In this case, instead of deleting the transmission destination information of all transmission history information stored in the parameter memory 3, the deletion processing for deleting the transmission destination information only for the transmission history information for an arbitrary transmission. May be performed.

  As described above, the network facsimile apparatus FX according to the present embodiment transmits at least predetermined information such as an image to a designated transmission destination, and when transmission processing is performed, the transmission date and time of the transmission processing, transmission destination information, and the like. Transmission history information is stored in the parameter memory 3 for each transmission, and when the transmission history information in the parameter memory 3 is output in a visible state at a predetermined time, the transmission history information for each transmission stored in the parameter memory 3 Of these, at least transmission destination information is erased for all transmissions or transmission history information for an arbitrary transmission.

  Therefore, it is possible to delete at least the transmission destination according to the operator's intention while leaving the fact that the transmission history information stored once has been transmitted, and to other users (operators) including the device administrator. It is possible to improve the security by preventing transmission history information such as transmission destination information from being seen.

  Further, the network facsimile apparatus FX of the present embodiment does not store in the operation display unit 13 all the transmission history information of the transmission or at least storage of the destination information of the transmission history information in the parameter memory 3 at the time of transmission. History information that includes a storage information selection key (storage information selection means) for performing selection, and controls the storage processing of the transmission history information of the transmission to the parameter memory 3 in accordance with the selection content of the storage information selection key at the time of transmission A storage control process is executed.

  That is, the network facsimile apparatus FX has a storage information selection mode, and when the storage information selection mode is selected by a key operation of the operation display unit 13, a storage history information storage selection screen 30 as shown in FIG. The stored information is displayed on the display of the unit 13, and the user is prompted by the key operation of the operation display unit 13 to select a storage information selection operation for selecting transmission history information to be stored in the parameter memory 3 from the transmission history information.

  For example, in FIG. 5, “store all” for selecting storage of all transmission history information in the parameter memory 3, “not store all” for selecting non-storage of all transmission history information in the parameter memory 3, and transmission A selection icon “Do not store destination” is selected on the storage selection screen 30 of the operation display unit 13 to select whether to store only the destination information in the parameter memory 3 from the history information, and hatched “ This indicates a state in which “store all” is selected. For example, the arrow key of the operation display unit 13 is used to select any of “store all”, “do not store all”, and “do not store destination” A selection operation is performed by selecting an icon and pressing the OK key.

  That is, in the case of FIG. 5, as the history information storage control process, not only the case where only the destination information is not stored among the transmission history information but also the case where all the transmission history information is not stored is shown. Yes.

  When the network facsimile apparatus FX performs a storage information selection operation for selecting whether or not to store the transmission history information in the parameter memory 3 by performing a key operation on the operation display unit 13 during transmission, Depending on the selection result of the stored information selection operation, all transmission history information is stored in the parameter memory 3, all transmission history information is not stored, or only the destination information is not stored in the transmission history information. . That is, when “store all” is selected on the storage selection screen 30 of the operation display unit 13, all transmission history information is stored in the parameter memory 3, and “do not store all” is selected. If all the transmission history information is not stored in the parameter memory 3 and "Do not store destination" is selected, only the transmission destination information of the transmission history information is stored in the parameter memory 3. Do not memorize.

  Then, the system control unit 1 reads the transmission history information in the parameter memory 3 at a predetermined time, and records and outputs it on a recording sheet with the plotter 6 as shown in FIG. Displayed on the display of the unit 13, converted into a specific format, attached to an e-mail, and sent to another network facsimile apparatus FX connected to the network NW via the LAN transmission control unit 9 And visualize. In the communication management report 22 of FIG. 6, for the transmission history information at 17:12 on December 16, “Do not store partner” is selected on the storage selection screen 30 of the operation display unit 13 at the time of transmission. The destination name as transmission destination information is not stored in the parameter memory 3, and the transmission history information at 20:31 on December 16 is temporarily set as described above. This shows a case where the destination name is overwritten by the “*” information and is erased in the erasure process, although stored in the memory 3.

  As described above, the parameters of the transmission history information are selected according to the selection contents on the operation display unit 13 that performs selection to store at least the transmission destination information among all the transmission history information of the transmission or transmission history information at the time of transmission. When the transmission history information storage control process for controlling the storage process in the memory 3 is executed, all of the transmission history information or all of the transmission history information is determined according to the operator's intention while leaving the transmitted fact without performing any setting in advance. Storage of at least transmission destination information in the parameter memory 3 of the transmission history information can be prohibited, and it is more reliably prevented from being seen by other users (operators) including the device administrator. Security can be further improved.

  Further, the network facsimile apparatus FX according to the present embodiment designates a transmission destination in advance on the operation display unit 13, and at least the destination of all transmission history information of transmission to the transmission destination or the transmission history information. History information that includes a storage information setting key for setting information not to be stored, and that controls the storage processing of the transmission history information of the transmission in the parameter memory 3 according to the setting content of the storage information setting key at the time of transmission A storage control process is executed.

  That is, the network facsimile apparatus FX has a storage information selection mode. When the storage information selection mode is selected by a key operation of the operation display unit 13, a storage selection screen for transmission history information for each transmission destination is displayed. A storage information selection operation for selecting transmission history information to be stored in the parameter memory 3 from among the transmission history information is displayed for each transmission destination by a key operation on the operation display unit 13 displayed on the display of the operation display unit 13. It is possible.

  The network facsimile apparatus FX stores the result of the storage information selection operation in this storage information selection mode as non-stored only in the transmission destination information in the parameter memory 3 for each transmission destination as shown in FIG. Stored information selection result information indicating whether or not to store all transmission history information is stored.

  Then, when performing the transmission process, the network facsimile apparatus FX controls the storage of the transmission history information in the parameter memory 3 based on the storage information selection result information in the parameter memory 3. For example, as shown in FIG. 7, with respect to transmission to the “HR department”, storage of only the transmission destination information in the transmission history information in the parameter memory 3 is not stored, and transmission to “HONGKONG BR.” Is performed. On the other hand, the storage information selection result information for not storing all the transmission history information in the parameter memory 3 is stored in the parameter memory 3.

  When the network facsimile apparatus FX performs a transmission operation in a state where the stored information selection result information for each transmission destination is set and registered in the parameter memory 3, the network facsimile apparatus FX responds to the stored information selection result information in the parameter memory 3. Then, all the transmission history information is stored in the parameter memory 3, all the transmission history information is not stored, or only the destination information of the transmission history information is not stored. That is, when “store all” is set and registered as the storage information selection result information of the transmission destination in the parameter memory 3, all the transmission history information is stored in the parameter memory 3, and “all is not stored”. ”Is set and registered, all transmission history information is not stored in the parameter memory 3, and when“ Do not store destination ”is set and registered, the transmission destination in the transmission history information Information is not stored in the parameter memory 3 only.
