Description

  The present invention relates to an image forming apparatus such as a copying machine and a multifunction machine.

  In an image forming apparatus such as a multifunction peripheral, an image forming process by a print engine, an image reading process by a scan engine, a screen display process by an operation display unit, a facsimile transmission / reception process, an Internet facsimile machine are performed by a controller having a CPU (Central Processing Unit). All processes such as transmission / reception processing, e-mail transmission processing, FTP (File Transfer Protocol) transmission processing, and SMB (Server Message Block) transmission processing are controlled in an integrated manner. The operation display unit is configured by a touch panel or the like, and includes a unique CPU separately from the controller. The CPU of the operation display unit controls processing such as screen display processing and operation instruction input processing in the operation display unit based on communication with the CPU of the controller.

  In the operation display unit, in the transmission functions such as facsimile transmission, Internet facsimile transmission, e-mail transmission, FTP (File Transfer Protocol) transmission, and SMB (Server Message Block) transmission, the same destination is sent one character at a time for each transmission. A one-touch destination setting button is provided to save input. This one-touch destination setting button is an operation button displayed on the touch panel. When pressed, this button can set a destination such as a facsimile number or an e-mail address registered for each button as a destination. is there. The user can easily set the transmission destination by pressing this one-touch transmission destination setting button.

  By the way, in the above prior art, when the one-touch transmission destination setting button on the operation display unit is pressed, the CPU of the operation display unit sends the detailed destination information registered in the pressed one-touch transmission destination setting button to the controller. Until the request is received and all of the detailed address information is received from the controller and the screen update based on the detailed address information is completed, pressing of the operation keys (hard keys) and the operation buttons displayed on the touch panel is not accepted. . However, in the above prior art, the operation display unit takes about 1 second or more until it receives all of the detailed destination information from the controller, that is, it does not accept pressing of the operation key and operation button for more than about 1 second. For this reason, the user feels uncomfortable with the operability of the operation display unit.

  For example, when setting a plurality of destinations as destinations, even if the user continuously presses the one-touch destination setting button, after pressing the one-touch destination setting button to set the first destination, Even if the next one-touch destination setting button is pressed immediately (within about 1 second) to set the second destination, the operation display unit does not accept the pressing of the next one-touch destination setting button. Do not set the destination. The reason why it takes about 1 second for the operation display unit to receive all the destination detailed information is that the controller stores the attribute information for each destination as the destination detailed information together with the destination such as the facsimile number and the e-mail address. This is because it takes some time to search and send the detailed destination information.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to provide an image forming apparatus capable of reducing discomfort felt in the operability of setting a transmission destination in a transmission function.

  In order to achieve the above object, according to the present invention, as a first solving means related to an image forming apparatus, an operation unit having a transmission function and receiving an operation instruction, a display unit displaying a predetermined screen, and the operation And an operation display control unit configured to control the display unit, and a controller that outputs a control signal to the operation display control unit, and is registered in advance as a transmission destination in a transmission function. When the operation unit accepts a one-touch transmission destination setting instruction for storing the detailed destination information, which is detailed information on the destination, the controller stores and sets a destination registered in advance by a one-touch operation as a transmission destination of the transmission function, the operation display The control unit sets a destination registered in advance as a transmission destination based on the one-touch transmission destination setting instruction, and causes the display unit to display the destination In the image forming apparatus, when the operation unit receives a one-touch transmission destination setting instruction, the operation display control unit invalidates operation instructions other than the one-touch transmission destination setting instruction received by the operation unit, and detailed destination information When the acquisition request is transmitted to the controller, and the controller receives the destination detailed information acquisition request, if the corresponding destination detailed information exists, the controller first includes the destination information included in the corresponding destination detailed information. A detailed information presence notification is transmitted to the operation display control unit, and then destination detailed information is transmitted. When the operation display control unit receives the destination detailed information presence notification, the destination included in the destination detailed information presence notification When the destination detailed information is received from the controller after the information is displayed on the display unit, the destination detailed information is stored, and the one-way information is stored. When a predetermined time elapses after receiving the transmission destination setting instruction, the screen is updated on the display unit based on the stored destination detailed information and operation instructions other than the one-touch transmission destination setting instruction are validated. Adopt the means.

  In the present invention, as the second solving means relating to the image forming apparatus, a means is used in which the destination information is a destination name and a destination in the first solving means.

  According to the present invention, in the image forming apparatus, when the operation unit receives a one-touch transmission destination setting instruction, the operation display control unit invalidates operation instructions other than the one-touch transmission destination setting instruction received by the operation unit thereafter, When the controller receives the destination detailed information acquisition request and the destination detailed information exists, the controller first sends the destination detailed information including the destination information included in the destination detailed information. The presence notification is transmitted to the operation display control unit, and then the destination detailed information is transmitted. Upon receiving the destination detailed information presence notification, the operation display control unit displays the destination information included in the destination detailed information presence notification on the display unit. After that, when receiving the destination detailed information from the controller, the destination detailed information is stored, and after receiving the one-touch transmission destination setting instruction The constant time elapses, to enable operation instruction other than the one-touch destination setting instruction causes updated on the display unit a screen based on the destination detailed information stored.

  In the conventional apparatus, the next one-touch transmission destination setting instruction is not validated until the destination detailed information is received and the screen update is completed. However, in the image forming apparatus according to the present invention, the one-touch transmission destination setting instruction is not performed. Even if it is accepted, by immediately accepting the next one-touch destination setting instruction, the user can immediately set the next destination as the destination, thus reducing the discomfort felt by the operability of the destination setting. I can do it.

Next, the operation of the MFP A according to the present embodiment having the above configuration will be described in detail with reference to FIGS. 3 and 4 are sequence diagrams showing operations of the CPU 1a and the operation display control processing unit 7c-1 of the multi-function peripheral A according to the present embodiment.
First, a user who intends to execute facsimile transmission, which is one of the transmission functions, by the multifunction peripheral A operates the operation buttons displayed on the hard key group 7b of the operation display unit 7 or the touch panel 7a, thereby setting the transmission destination setting basics. A screen is displayed on the touch panel 7a. Then, the user presses the one-touch transmission destination setting button on the transmission destination setting basic screen displayed on the touch panel 7a in order to set the transmission destination.

  FIG. 5 is a diagram showing a transmission destination setting basic screen of the multifunction peripheral A according to the present embodiment. As shown in FIG. 5, the transmission destination setting basic screen is provided with a one-touch transmission destination setting button and a transmission destination display area. The one-touch destination setting button is a button for setting a destination registered in advance as a destination by a one-touch operation, and a destination name (company name, personal name, etc.) and a destination code are displayed on the button. The transmission destination setting basic screen is provided with a one-touch button switching button for switching to a one-touch transmission destination setting button that cannot display the display on the touch panel 7a.

  In the transmission destination display area, a destination set as a transmission destination by pressing the one-touch transmission destination setting button and a destination name are displayed. Furthermore, an operation button for performing various operations on the destination set as the operation destination, and a message display area for displaying the number of transmission destinations and various messages are provided. The icon on the one-touch destination setting button that displays the destination code “001” indicates that the FTP transmission destination is registered, and the icon on the one-touch destination setting button that displays the destination code “002” is Indicates that the destination of facsimile transmission is registered. An icon on the one-touch destination setting button displaying the destination code “003” indicates that the destination of the e-mail transmission is registered.

  When the operation display control processing unit 7c-1 receives the coordinate detection signal by pressing the one-touch transmission destination setting button of the destination code “002” displayed on the touch panel 7a, the operation display control processing unit 7c-1 receives the one-touch transmission destination setting instruction of the destination code “002”. Judgment is made (step S1). Then, after step S1, the operation display control processing unit 7c-1 disables the hard key group 7b and the operation buttons other than the one-touch transmission destination setting button and the one-touch button switching button (step S2), and based on the destination simplified information. In response to the pressed one-touch transmission destination setting button, a detailed destination information acquisition request for the destination code “002” is transmitted to the CPU 1a (step S3).

  When the CPU 1a receives the destination detailed information acquisition request for the destination code “002” from the operation display control processing unit 7c-1, the CPU 1a searches for the destination detailed information for the destination code “002” in the destination detailed information storage unit 1d. If the destination detailed information of the destination code exists, a destination detailed information presence notification including the destination name and destination included in the destination detailed information of the destination code “002” as information is transmitted to the operation display control processing unit 7c-1 (step S1). S4).

  When the operation display control processing unit 7c-1 receives the destination detailed information presence notification with the destination code “002” from the CPU 1a, the destination name and destination of the destination code “002” included in the destination detailed information presence notification are transmitted to the touch panel 7a. It is displayed in the previous display area (step S5). Note that it takes about 0.003 seconds from when the operation display control processing unit 7c-1 transmits the destination detailed information acquisition request to the reception of the destination detailed information presence notification.

  When the operation display control processing unit 7c-1 receives the coordinate detection signal by pressing the one-touch transmission destination setting button for the destination code “004” displayed on the touch panel 7a, the operation display control processing unit 7c-1 issues a one-touch transmission destination setting instruction for the destination code “004”. It is determined that it has been accepted (step S6). Then, after step S6, the operation display control processing unit 7c-1 disables the operation of the hard key group 7b and the operation buttons other than the one-touch transmission destination setting button and the one-touch button switching button (step S7). In response to the one-touch destination setting button pressed based on this, a destination detailed information acquisition request with the destination code “004” is transmitted to the CPU 1a (step S8).

  When the CPU 1a receives the destination detailed information acquisition request with the destination code “004” from the operation display control processing unit 7c-1, the CPU 1a searches whether the destination detailed information with the destination code “004” exists in the destination detailed information storage unit 1d. If the destination detailed information of the destination code exists, a destination detailed information presence notification including the destination name and destination included in the destination detailed information of the destination code “004” as information is transmitted to the operation display control processing unit 7c-1. S9).

  When the operation display control processing unit 7c-1 receives the destination detailed information presence notification with the destination code “004” from the CPU 1a, it transmits the destination name and destination of the destination code “004” included in the destination detailed information presence notification to the touch panel 7a. It is displayed in the previous display area (step S10).

Then, the CPU 1a sequentially transmits destination detailed information including the destination name and destination of the destination code “002” to the operation display control processing unit 7c-1 (Step S11), and all the destination detailed information of the destination code “002” is transmitted. Upon transmission, a destination detailed information transmission completion notification of the destination code “002” is transmitted to the operation display control processing unit 7c-1 (step S12).
When the operation display control processing unit 7c-1 receives the destination detailed information including the destination name and destination of the destination code “002” from the CPU 1a in step S11, the destination detailed information of the destination code “002” is stored in the operation display ROM 7d. Store (step S13).

Further, after step S12, the CPU 1a sequentially transmits destination detailed information including the destination name of the destination code “004” and the destination to the operation display control processing unit 7c-1 (step S14), and the destination of the destination code “004”. When all the detailed information is transmitted, a destination detailed information transmission completion notification of the destination code “004” is transmitted to the operation display control processing unit 7c-1 (step S15).
When the operation display control processing unit 7c-1 receives the destination detailed information including the destination name and destination of the destination code “004” from the CPU 1a in step S14, the destination display detailed information of the destination code “004” is stored in the operation display ROM 7d. Store (step S16).

  Then, the operation display control processing unit 7c-1 receives a coordinate detection signal by pressing the one-touch transmission destination setting button for the destination code “004”. That is, after receiving a one-touch transmission destination setting instruction for the destination code “004”, the operation display control processing unit 7c-1 When the time (0.4 seconds) elapses, the destination setting basic screen is updated based on the destination detailed information of the destination code “002” and the destination code “004”, and the hard key group 7b and all the operation buttons are pressed. Enables all the operation instructions received by the operation display unit 7 (step S17).

  Specifically, in step S17, the operation display control processing unit 7c-1 updates the number of transmission destinations together with the message in the message display area, and the destinations included in the destination detailed information of the destination codes “002” and “004”. The transmission destination display area is updated based on the name and the destination, and the operation button that cannot be executed is grayed out based on the prohibition information included in the attribute information of the destination detailed information of the destination code “004”. For example, when the one-touch transmission destination setting button for email transmission is pressed, the “Tel Now” button of the operation button is grayed out based on the prohibition information of the detailed destination information. The “Tel Now” button is a button that is pressed to activate a function for confirming establishment of a telephone network line in facsimile transmission.

  The reason why the operation display control processing unit 7c-1 updates the transmission destination setting basic screen based on the prohibition information included in the attribute information of the detailed destination information of the destination code “004” in step S17 is the destination code Because the one-touch destination setting button “004” is pressed, the destination name and destination of the destination code “004” displayed in the destination display area are in focus, and the destination details of the destination in focus This is because the prohibition information included in the attribute information of the information is reflected on the transmission destination setting basic screen.

  Further, the operation display control processing unit 7c-1 updates the screen and performs an operation when a predetermined time (0.4 seconds) elapses after the one-touch transmission destination setting button is pressed for the second time in step S17. When enabled, but the one-touch destination setting button is pressed three times, the screen is updated when a predetermined time (0.4 seconds) elapses after the one-touch destination setting button is pressed for the third time. And make the operation valid. That is, when the one-touch transmission destination setting button is continuously pressed, the operation display control processing unit 7c-1 has passed a predetermined time (0.4 seconds) since the last time the one-touch transmission destination setting button was pressed. Then, the screen is updated and the operation is enabled.

  Specifically, every time the one-touch transmission destination setting button is pressed, the operation display control processing unit 7c-1 starts an elapsed time counting timer for each one-touch transmission destination setting button. The operation display control processing unit 7c-1 measures a predetermined time (0.4 seconds) with this elapsed time timer, and when the elapsed time timer expires, the operation display control processor 7c-1 determines a predetermined time ( 0.4 seconds) has passed. Then, the operation display control processing unit 7c-1 finally presses the one-touch transmission destination setting button when the one-touch transmission destination setting button is continuously pressed within a predetermined time (0.4 seconds). When the elapsed time timer that has been started is timed out, step S17 is executed.

As described above, in the MFP A according to the present embodiment, when the operation display control processing unit 7c-1 determines that the one-touch transmission destination setting instruction is received, the hard keys other than the one-touch transmission destination setting button and the one-touch button switching button are used. The group 7b and the operation buttons are disabled, and a destination detailed information acquisition request is transmitted to the CPU 1. When the operation display control processing unit 7c-1 receives the destination detailed information presence notification from the CPU 1a, the operation display control processing unit 7c-1 displays the destination name and the destination included in the destination detailed information presence notification on the touch panel 7a, and then receives the destination received from the CPU 1. The destination name and the remaining information other than the destination included in the detailed information are stored in the operation display ROM 7d, and when a predetermined time (0.4 seconds) elapses after the one-touch transmission destination setting instruction is received, the operation display ROM 7d is stored. The transmission destination setting basic screen is updated based on the detailed destination information, and all operation instructions received by the operation display unit 7 are validated by pressing the hard key group 7b and all operation buttons.
In the conventional device, the press of the next one-touch transmission destination setting button is not validated until the destination detailed information completion notification is received and the screen update is completed. However, in the MFP A according to the present embodiment, the one-touch transmission is performed. Even if the destination setting button is pressed, by allowing the user to immediately press the next one-touch destination setting button, the user can immediately set the next destination as the destination. Discomfort felt by sex can be reduced.
