[Operation of image forming apparatus equipped with data communication apparatus]
FIG. 3 is an operation flowchart related to destination determination or transmission processing of the image forming apparatus equipped with the data communication apparatus according to the present invention, and FIG. 4 shows an example of a display screen for prompting an operation input related to required destination information. FIG. 5 is an explanatory diagram illustrating an example of a warning display screen displayed when all pieces of destination information based on a plurality of viewpoints do not match destination information related to a required destination, and FIG. 6 illustrates a plurality of viewpoints. FIG. 7 is an explanatory diagram showing an example of a screen displayed when destination information is acquired based on an IP address among destination information based on FIG. 7, and FIG. 7 illustrates destination information based on a host name among destination information based on a plurality of viewpoints. It is explanatory drawing which shows the example of a screen displayed when information is acquired.

  As shown in FIG. 3, when the user inputs an operation key unit 55 to select an image data transmission job conforming to the direct SMTP method related to a desired destination (step S11), the destination determination or transmission processing is performed below. Such programs are sequentially executed.

  In step S12, the main control unit 11 displays on the display screen of the touch panel unit 53 a display screen that prompts an operation input related to required destination information (for example, IP address, domain name, or host name) (see FIG. 4). Is displayed. On this display screen, the main control unit 11 waits for an operation input by the user for the IP address, domain name or host name related to the required destination. At this time, after the user inputs the destination information related to the IP address and the domain name or the combination of the IP address and the host name among the IP address or the domain name or the host name related to the required destination, It is assumed that the “OK” button is pressed (step S13).

  In response, the multi-input determination unit 75 performs multi-input determination regarding whether or not the destination information based on a plurality of viewpoints has been input based on the destination information input in operation in step S13 (step S14). Specifically, for example, in the destination information input operation prompting screen shown in FIG. 4, an operation input of destination information related to any combination pattern of IP address and domain name or IP address and host name is made. In such a case, the multiple input determination unit 75 determines that destination information based on multiple viewpoints has been input. Instead of this example, when an operation input of destination information related to a combination pattern of an IP address, a domain name, and a host name is made, the multi-input determination unit 75 receives destination information based on a plurality of viewpoints. You may comprise so that the determination to this effect may be made.

  As a result of the multiple input determination in step S14, it is determined that destination information based on multiple viewpoints is not input, that is, it is determined that only one of the IP address, domain name, or host name has been input. The main control unit 11 displays an error message indicating that “destination information based on a plurality of viewpoints has not been input” on the display screen of the touch panel unit 53 (step S15). The flow is returned to the destination information input operation prompt screen display in step S12, and the following processing is repeatedly executed.

  On the other hand, as a result of the multiple input determination in step S14, the fact that destination information based on multiple viewpoints has been input, that is, IP address and domain name, or IP address and host name, or IP address, domain name, and host. When it is determined that an operation input of destination information related to any one of the patterns is made, the consistency determination unit 77 determines the plurality of viewpoints based on the storage contents of the destination information storage unit 74. The consistency determination is performed as to whether or not all the destination information based on the information matches the destination information related to the required destination (step S16). In step S16, the consistency determination unit 77 determines whether or not the destination information based on the plurality of viewpoints input in operation in step S13 means that one destination is used together. It plays a role.

  As a result of the consistency determination in step S16, when it is determined that all the destination information based on the plurality of viewpoints matches the destination information related to the required destination, the destination confirmation control unit 79 Control is performed to permit destination determination with destination information relating to the required destination (step S17). Here, “permit destination determination” means that the destination information input in step S13 is correct and correct, and the actual destination determination is performed after the start key 57 is input. The concept includes both the concept and the concept of determining the actual destination without waiting for the operation input of the start key 57.

  Next, the SMTP communication unit 81 transmits image data according to the direct SMTP method to the destination determined in step S17 with the external device 69 via the network 67 (step S18). After performing the above, a series of processing flow is terminated.

  In the above-described series of processing flows, as a result of the consistency determination in step S16, it is determined that any of the destination information based on the plurality of viewpoints is not consistent with the destination information related to the required destination. If the message is issued, the image data cannot be transmitted. Therefore, there is a problem as to what measures should be taken in order to avoid the worst situation as much as possible, to give the user a sense of security and not to impair the convenience of the user.

  From such a viewpoint, as a result of the consistency determination in step S16, when it is determined that any of the destination information based on the plurality of viewpoints does not match the destination information related to the required destination, the display control unit No. 83 notifies the user of the inconsistency by performing control to display that the destination information is inconsistent on the display screen of the touch panel unit 53 (step S15, see FIG. 5). .

  That is, for example, on the operation input prompt screen shown in FIG. 4, after the user inputs an IP address (192.168.1.200) and a host name (KM5D4F4B) as destination information based on a plurality of viewpoints, the “OK” button is pressed. Suppose that it is pressed. At this time, for example, as shown in FIG. 5, a warning message indicating that the IP address (192.168.1.200) and the host name (KM5D4F4B) are inconsistent is displayed on the display screen of the touch panel unit 53. We decided to inform the user of the inconsistency.

  As a result, the user can explicitly know the reason why the image data cannot be transmitted, as a result, as compared with the case where the user is forced to feel uneasy without clearly knowing the cause. Except for mental stress, the user can be given a sense of security.

  Further, in view of improving the convenience of the user, the display control unit 83 determines that any of the destination information based on the plurality of viewpoints is set as the required destination as a result of the consistency determination in the consistency determination unit 77. When it is determined that the information does not match the destination information, the connection button 91 (see FIG. 4) operated when acquiring the information of each destination related to the destination information based on the plurality of viewpoints via the LAN 67 is displayed. Then, control to display on the display screen of the touch panel unit 53 is performed.

  Furthermore, when the connection button 91 corresponding to any one of the destinations related to the destination information based on the plurality of viewpoints is operated, the display control unit 83 displays the corresponding destination information on the display screen of the touch panel unit 53. It was decided to control the display.

  That is, for example, it is assumed that the user presses the connection button 91 corresponding to the IP address (192.168.1.200) on the operation input prompt screen shown in FIG. At this time, for example, as shown in FIG. 6, as the information of the destination having the corresponding IP address (192.168.1.200), the IP address (192.168.1.200), the host name (KM6882C0), and the MAC address (00: C0: EE : 68: 82: C0) is displayed on the display screen of the touch panel unit 53 to inform the user of information related to the destination candidate (IP address (192.168.1.200)) that is the cause of the transmission failure. did.

  On the other hand, for example, assume that the user presses the connection button 91 corresponding to the host name (KM5D4F4B) on the operation input prompt screen shown in FIG. At this time, for example, as shown in FIG. 7, as the information of the destination having the corresponding host name (KM5D4F4B), the IP address (192.168.1.150), the host name (KM5D4F4B), and the MAC address (00: C0: EE: 69 : 81: C0) is displayed on the display screen of the touch panel unit 53, thereby informing the user of information related to the destination candidate (host name (KM5D4F4B)) that is the cause of the transmission failure.

  As a result, the user can clearly know which destination candidate is the required destination by referring to the information related to the destination candidate. Data transmission processing can be performed toward a required destination, which can contribute to improvement of user convenience.
